Cato Networks, a leader in secure access service edge (SASE), has completed its first acquisition by purchasing Aim Security, a fast-growing AI security firm backed by YL Ventures and Canaan Partners.
The deal is aimed at strengthening Cato’s SASE Cloud Platform by integrating advanced AI security capabilities that protect enterprises adopting both public and private AI applications.
The acquisition marks a significant step in Cato’s expansion strategy. While the value of the transaction has not been disclosed, it comes as the company reported surpassing $300m in annual recurring revenue. At the same time, Cato confirmed an extension of its Series G funding round with an additional $50m from Acrew Capital, bringing the total raised in the round to $409m.
Cato has pioneered the SASE market with its cloud-native platform that connects and secures enterprise resources, from employees and devices to clouds and applications. The company is now positioning itself as a critical control point for AI interactions across business environments, with visibility into AI agents, models, servers and applications.
Aim Security, founded in 2022, has quickly established itself as a trusted AI security provider for major global organisations, including Fortune 500 firms. Its platform covers three key areas: securing employee use of public AI tools such as Microsoft Copilot and coding agents, protecting internal AI applications and agents with an AI Firewall, and safeguarding the AI development lifecycle through AI Security Posture Management (AI-SPM). Aim’s research team also uncovered “EchoLeak”, the first reported zero-click AI vulnerability in Microsoft 365 Copilot.
Cato said Aim’s technology will be integrated into its own SASE Cloud Platform by early 2026, enabling clients to deploy AI security capabilities through a single converged system. Current Aim customers will have a migration path from standalone services to Cato’s integrated platform.
Cato Networks CEO and co-founder Shlomo Kramer said, “AI transformation will eclipse digital transformation as the main force that will shape enterprises over the next decade. With the acquisition of Aim Security, we’re turbo-charging our SASE platform with advanced AI security capabilities to secure our customers’ journey into the new and exciting AI era.”
Aim Security co-founder and CEO Matan Getz said, “One of the world’s largest financial services companies deployed Aim to secure its AI adoption. Aim had purpose-built a broad AI security platform, grounded in cutting-edge research and patented technology, designed to seamlessly integrate into complex enterprise environments. Aim’s solutions enable businesses to securely reap the benefits of their AI investments.”
