In a bold and timely move befitting a mature AI-security era, Israeli-founded Cato Networks—already a rising star in the Secure Access Service Edge (SASE) market—has made its first-ever acquisition, Scooping up fledgling AI-security startup Aim Security for an estimated $300–$350 million, paid in a mix of cash and shares. The deal vaults Cato’s capabilities into the AI security stratosphere by embedding Aim’s platform—which protects against shadow AI use, shields private AI agents, and secures the entire AI development lifecycle—directly into Cato’s global SASE fabric. Backed by firms like YL Ventures and Canaan Partners, Aim brings not just tooling but top-notch research—including identifying the “EchoLeak” zero-click threat—to the table. At the same time, Cato boosted its Series G round with an extra $50 million, bringing the total to $409 million, while its annual recurring revenue has surged past $300 million—a tidy sum that provides financial fuel for strategic growth as enterprises rush headlong into AI-powered futures.

In-Depth
It’s clear that the AI wave isn’t just cresting—it’s morphing into a tsunami, and for companies like Cato Networks, standing idle simply isn’t an option. With its roots firmly planted in the SASE space—fusing secure networking and cybersecurity into one cloud-delivered standard—Cato was already pushing envelope. But by acquiring Aim Security for around $350 million, Cato is telling the world: AI security isn’t a feature, it’s foundational.
Founded in 2015 by industry veterans, Cato has steadily built momentum. Now, with annual recurring revenues topping $300 million and a freshly extended $409 million funding round, the company isn’t just talking growth—it’s bankrolling it. Aim Security, in turn, brings laser-focused technology that spans core needs: securing user interactions with AI—including shadow use of tools like ChatGPT or Copilot—protecting internal AI agents and applications at runtime, and managing security across the AI development lifecycle. This isn’t mere patchwork; it’s comprehensive, threat-aware design, complete with research-driven insights like the “EchoLeak” vulnerability in Microsoft 365 Copilot.
For enterprises scrambling to deploy AI responsibly, Cato’s move offers something rare: a unified, cloud-native AI-security layer seamlessly embedded into a broader network security platform. CIOs and CISOs won’t have to stitch together point solutions; instead, Cato provides a one-stop architecture that scales globally, simplifies governance, and keeps pace with ever-shifting AI threat vectors. Compared to past tech transformations—think firewalls in the web era or CASB tools in the SaaS era—AI security demands a new stack. Cato’s acquisition of Aim isn’t just a smart acquisition; it’s a preemptive strike for the next chapter in enterprise IT security.
