Cato Networks Acquires Aim Security, Expands Financing, and Crosses $300M ARR

In the latest sign of consolidation in cybersecurity and networking, Cato Networks has acquired Aim Security, a fast-growing AI security firm, to strengthen its push into securing enterprise AI adoption. The deal brings new AI protection capabilities into the Cato SASE Cloud Platform, extending its role as a central control point for enterprise traffic, applications, and now, AI interactions.

At the same time, Cato announced it surpassed $300 million in annual recurring revenue and expanded its Series G financing round. An additional $50 million from Acrew Capital brings the total to $409 million, on the same terms and valuation as the round announced in June.

Why AI Security Fits Into SASE

With AI reshaping enterprise workflows, it is creating new security, privacy, and compliance risks. Because SASE already sits at the core of enterprise connectivity - linking people, devices, locations, clouds, and applications - it’s well-positioned to monitor and enforce policy on AI usage.

Cato Networks’ acquisition of Aim Security underscores how serious this shift is. Every IT wave has expanded the attack surface. AI is no different, but adoption is happening at breakneck speed. Employees are experimenting with public tools, business units are deploying copilots, and developers are building custom agents. Without guardrails, this activity introduces real data, compliance, and security exposures.

Aim Security exists to address this problem. Its platform protects AI that is consume, built, and the full AI lifecycle. That end-to-end coverage - proven at scale - seemed like the strongest path for Cato to help customers secure their AI transformation. By embedding Aim’s inspection capabilities into the Cato SASE Cloud Platform, the company extends its control point over enterprise traffic to include AI interactions. This isn’t just data loss prevention applied to AI, but purpose-built defense for a new attack surface.

For enterprises, the value is clear: unified protection across all AI use cases, consolidation instead of scattered point tools, and defenses informed by research to stay ahead of adversaries. In the near term, Aim will remain available as a standalone product. By 2026, it will fully converge into the Cato platform - giving customers the option to adopt AI security today and transition seamlessly when they’re ready.

Founded in 2022, Aim Security has built a platform that addresses three big use cases:

Aim’s research team has also uncovered vulnerabilities, including a recent zero-click flaw in Microsoft 365 Copilot dubbed EchoLeak (CVE-2025-32711).

Converging AI Security With Cato’s Platform

Cato built its SASE platform as a cloud-native fabric, designed to secure all enterprise traffic from any source to any destination. Adding Aim’s AI expertise extends that reach into a growing and unpredictable attack surface. With global visibility, unified policy enforcement, and AI-specific defenses, Cato is positioning itself to secure enterprise AI adoption at scale.

Customers can deploy Aim’s technology immediately. Longer term, Cato plans to fully integrate Aim into the Cato SASE Cloud Platform by early 2026, offering a seamless path for those who adopted Aim as a standalone solution.

Cato has steered enterprises through every major IT shift. AI is the next one, and the mission hasn’t changed: adopt what’s new without losing security or scale. With ARR over $300 million and fresh backing, Cato is making clear that securing AI now belongs alongside networks and applications.
