Cato Networks

Cato Networks builds the Cato SASE Platform, described as the world's first Secure Access Service Edge platform: a cloud-native architecture that converges networking and security into a single service. The platform delivers threat prevention, data protection, and incident detection and response through a globally distributed cloud network, replacing stacks of point products and physical appliances while optimising connectivity for users, sites, and applications. Its technical span is broad - SD-WAN, firewall, VPN, web security, cloud-native networking and threat prevention sit within one system rather than a vendor consortium.

Founded in 2015 by cybersecurity veterans Shlomo Kramer and Gur Shatz, whose prior work includes Check Point Software Technologies and Imperva, the company set out from a specific observation: that fragmented point solutions in traditional network-security architectures fail enterprises. The approach proved consequential enough that Gartner coined the term 'SASE' to describe the category the product created. The firm claims category leadership as the first SASE platform, in a market projected to reach $28.5 billion by 2028.

Engineering work here touches the hard problems at the intersection of enterprise IT, cybersecurity, cloud adoption and remote work - global traffic engineering, policy enforcement at cloud scale, and detection and response embedded in the network itself. The footprint is inherently global, matched to the architecture. For practitioners who wish to build at the layer where networking and security are one problem rather than two, this is an unusually coherent place to do it.
