Aim’s AI-security tools are intended to protect employee use of AI apps, enterprise agents, and private AI systems, while Cato plans to fold those capabilities into its SASE platform. Cato said platform integration was planned for early 2026; it did not disclose the purchase price.
Why did Cato Networks buy Aim Security?
The strategic rationale is to bring AI-specific controls into Cato’s existing network-and-security platform. Cato describes its SASE Cloud Platform as a control point for enterprise traffic; Aim adds protections for the interactions among employees, AI applications, agents, models, MCP servers, and APIs. The combination is intended to detect and stop threats, risky or anomalous access, and data breaches involving those interactions. This platform-convergence rationale follows the companies’ stated product descriptions; it is not a disclosed financial forecast.
Cato 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.” He characterized the acquisition as a way to “turbo-charge” Cato’s SASE platform with AI-security capabilities.
What does Aim Security do?
Founded in 2022 and backed by YL Ventures and Canaan Partners, Aim Security focuses on enterprise AI security. Its announced product scope spans employee use, runtime protection, and AI-system development:

- Employee use of AI: Security for public AI applications and enterprise agents such as Microsoft Copilot.
- Private AI apps and agents: An AI Firewall designed to detect runtime attacks and enforce governance policies.
- AI development lifecycle: AI Security Posture Management (AI-SPM) covering stages from model training through custom-agent creation.
Aim’s research team reported the first CVE for a zero-click Microsoft 365 Copilot vulnerability, EchoLeak (CVE-2025-32711). Cato presented this work as evidence of Aim’s AI-security expertise.
Is Aim Security part of Cato now?
Yes. Cato announced the acquisition on September 3, 2025, and called it the company’s first acquisition. For customers with immediate AI-security requirements, Cato said Aim could be deployed as a standalone product. The announcement described a planned path from that standalone deployment to Cato’s integrated platform.
When will Cato’s AI-security capabilities be available in its platform?
Cato planned to provide Aim capabilities within the Cato SASE Cloud Platform in early 2026, with a seamless migration path for customers already using Aim standalone. “Early 2026” was the timing stated in the September 2025 announcement, not confirmation that integration has since launched. Organizations evaluating availability should verify current product status and migration details directly with Cato.
How much did Cato pay for Aim Security?
Cato did not disclose the acquisition price in the company announcements cited here. The separate figures announced alongside the deal were Cato’s reported annual recurring revenue of more than $300 million and a $409 million Series G financing round. The Series G included a $50 million extension from Acrew Capital on the same terms and valuation as the earlier round; these financing and revenue figures are not the price paid for Aim.

What the deal means for enterprise AI-agent security
For enterprises, the acquisition signals an effort to bring AI security closer to the network and security controls already used to manage enterprise traffic. The product scope Cato described reaches beyond employee prompts to include private AI apps, agents, their connections to tools and APIs, and development-lifecycle posture. That breadth may make the combined offering relevant to organizations seeking a shared control plane, but the announcement alone does not establish comparative performance, deployment coverage, or effectiveness against specific threats.
Cato positioned Aim as serving advanced organizations, including Fortune 500 and Forbes Global 2000 companies. Buyers assessing the offering should map their own requirements across user-to-AI and agent-to-tool interactions, runtime defenses, development controls, standalone versus integrated deployment, and migration needs.
