Todayโ€™s Challenges

The open web is an open door.

Web-borne threats
Policy circumvention
Inconsistent enforcement
No web visibility

Web-borne threats

Phishing, malware delivery, and compromised sites expose users to attacks the moment a page loads.

Policy circumvention

Users preview images and video through search engines, bypassing organizational content and compliance policies.

Inconsistent enforcement

Web policy applied unevenly across users, locations, and devices leaves gaps โ€” and compliance risk.

No web visibility

Without normalized event data, security teams canโ€™t see who accessed what โ€” or prioritize their response.

Web threats

Policy bypass

Uneven policy

No visibility

Our approach

Filter the web.
Enforce it everywhere.

Web access is everywhere, and so is web-borne risk. Cato SWG inspects and controls all internet traffic from the cloud โ€” including encrypted sessions โ€” enforcing one access and threat policy for every user and location without backhauling to an appliance.

Microsoft Defender does some web filtering, but itโ€™s limited and not as configurable or easy to use as what we can do in Cato with all the different types of filtering groups and SWG features. Thereโ€™s a lot more flexibility weโ€™ll have in Cato.

FAQS

Answers to common questions

What web risks does Cato SWG protect against?1 question

What is Cato SWG and what does it protect against?

Cato SWG is a cloud-native Secure Web Gateway that inspects and controls internet traffic to enforce corporate web access policies. It helps protect users from a broad range of web-borne threats by identifying and blocking risky or malicious destinations before they load.

How does cloud-native SWG fit into a broader SASE architecture?3 questions

How does a cloud-native secure web gateway differ from traditional appliance-based approaches?

Traditional appliance-based SWGs add a separate security appliance to the local stack and require ongoing sizing, patching, and upgrades. Cato SWG delivers SWG capabilities from the Cato SASE Cloud, eliminating the need for a separate SWG appliance while applying consistent protection across users and locations.

How does Cato SWG fit into a broader security architecture?

Cato SWG is part of the converged Cato SASE Cloud platform. This means it operates alongside other networking and security capabilities within a single platform rather than functioning as an isolated point solution, providing consistent protection across the enterprise without managing separate tools.

How is Cato SWG recognized in the industry?

Cato Networks has been recognized as a Leader in the 2025 Gartner Magic Quadrant for SASE Platforms, a Leader and Outperformer in the GigaOm 2025 SASE Radar, and a Growth and Innovation Leader in SASE by Frost and Sullivan.

How does Cato SWG enforce web access policy across the enterprise?4 questions

How does Cato SWG handle policy enforcement across a distributed enterprise?

Cato SWG provides flexible, centrally managed policy controls that can be tailored to enterprise requirements and applied consistently across users and locations. Administrators can refine enforcement by user identity, location, and device posture, with options to allow, block, or prompt for each policy rule.

What web content categories and controls does the platform support?

Cato SWG classifies websites across 80+ or more categories. Administrators can block specific categories, customize notification pages, and set granular controls per user, location, or device. Safe Search can be enforced on popular search engines and content restrictions applied to YouTube in just a few clicks.

How does Cato SWG prevent users from bypassing content policies through search engines?

Cato SWG prevents users from bypassing content policies by enforcing Safe Search on popular search engines and applying YouTube content restrictions across all users and locations. These controls address image and video previews in search results that could otherwise circumvent organizational content and compliance policies.

What visibility and reporting capabilities are available?

Every web access event is logged and retained, giving administrators the data they need for visibility, compliance reporting, and security awareness training. Access attempts to blocked domains are also logged to support analysis and user education.
