About Cato Networks

Cato Networks sells the Cato SASE Cloud, a SASE platform built as a global cloud with a single-pass engine, a single data lake and single policy enforcement. Cato Networks describes its SASE platform as converging networking, security and access into a single, global, AI-powered cloud service. Cato Networks states that the platform delivers secure, optimized access from distributed points of presence close to users and business resources.[15]

Cato Networks states that day-to-day planning, scaling and maintenance depend on specialized, hard-to-find expertise. In the company's account, controls differ across users, sites, datacenters and cloud, leaving gaps as applications migrate. Cato Networks positions its platform as a replacement for point products, with a single policy and console running on an SLA-backed global backbone.[6][7]

The core of the platform is the Single Pass Cloud Engine, called SPACE. SPACE converges NGFW, threat prevention, and CASB, DLP and ZTNA into one cloud-native stack. Thousands of SPACEs run on bare-metal compute across worldwide PoPs, interconnected by tier-1 carriers. Every inspected flow feeds network, device, user, app and data context into one open data lake that is accessible through the Cato API. Cato Networks says NGFW, CASB, DLP, ZTNA, threat prevention and AI controls all run on a single policy engine.[6]

On the networking side, Cato Networks carries SD-WAN traffic over a private global backbone. Cato Networks connects sites to the Cato Cloud, where they are managed centrally. For access, Cato Networks offers adaptive, risk-based, zero-trust access to private applications located on-premises or in the cloud. The access methods include ZTNA Client, Enterprise Browser, Browser Extension and Clientless Portal. Cato Networks says these access methods can coexist with current access solutions and be selectively deployed to secure some or all application access.

Cato Networks discovers local, custom and managed agents across the enterprise, including their tools, MCP servers, data access and execution paths. Cato Networks controls prompts, responses, tool calls and tool actions before agents create business impact. Cato Networks says AI security can be deployed independently to protect AI usage and AI agents across the organization. Organizations can run AI Security for Applications on-prem or in their own cloud with AI Security Outposts.[9][10]

Other modules run on the same platform. Cato DLP offers a catalog of 350+ pre-defined data types covering common use cases for sensitive data, PII, and compliance. The Cato DLP engine inspects all traffic to private applications and SaaS apps. Cato EPP is fully managed through the Cato Management Application. Cato DNS Security inspects all DNS traffic in real time to prevent malicious activity hiding within the protocol, and it blocks DNS requests to malicious destinations before a connection is ever made. The Cato Management Application unifies configuration, monitoring and analytics in a single pane of glass.[12][13][14]

Cato Networks offers MDR, which delivers zero-footprint detection of persistent threats with no agents or appliances. Cato Networks monitors last-mile ISPs 24×7 at every site. On an outage or performance degradation, Cato Networks works with the ISP to resolve it. For management, customers can choose Cato or a qualified partner to help manage the networking and security environment. For site deployment, the zero-touch Cato Socket deploys quickly at customer premises, by the customer or with Cato and partner remote or on-site support. Customers can self-manage, co-manage with a partner and Cato, or hand over complete hands-free operations.[15]

On deployment, Cato Networks says zero-touch provisioning and self-service client rollout enable selective deployment by use case, geography, or org unit. Cato Networks says its modular platform coexists with existing infrastructure, allowing gradual adoption. Cato Networks says organizations can start with a specific capability such as SD-WAN, SSE, or ZTNA and expand over time without rearchitecting the environment.[6][12][13][14][15]
