Cato Networks Acquires Aim Security, Surpassed $300M ARR, and Expanded Financing Round to $409 Million

Cato Networks, the SASE leader, announced today that it acquired Aim Security, a visionary leader of AI security. This is Cato’s first-ever acquisition and will further expand the Cato SASE Cloud Platform, enabling secure enterprise adoption of AI agents and public and private AI applications. 

In addition, Cato announced it has surpassed $300 million in annual recurring revenue (ARR). Cato also extended its Series G financing round announced in June with an additional $50 million investment from Acrew Capital, bringing the total round to $409 million. The financing took place on the same terms and valuation. 

AI Transformation is the Next Frontier for SASE

AI is transforming businesses everywhere. At the same time, security, compliance, and privacy risks are introduced through new interaction models with enterprise data by people, AI agents, and AI models. With SASE becoming the de facto standard for a secure fabric connecting all enterprise resources, including employees, partners, locations, clouds, devices, and applications, SASE is uniquely positioned as a primary control point for all AI interactions.  

“AI transformation will eclipse digital transformation as the main force that will shape enterprises over the next decade,” said Shlomo Kramer, CEO and co-founder of Cato Networks. “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 Delivers a Complete AI Security Solution

Founded in 2022 and backed by YL Ventures and Canaan Partners, Aim has been at the forefront of the enterprise AI security category and shapes how some of the world’s most advanced organizations, including those in the Fortune 500 and Forbes Global 2000, harness AI with trust, control, and confidence. 

Aim’s leading AI security solution spans three AI security use cases, supported by a unified and advanced core engine:

• Securing Employee Use of Public AI Applications: Aim discovers shadow AI usage, monitors and protects all end-user AI interactions, unlocks visibility and risk mitigation for existing AI usage, and enables net-new AI use cases. With Aim, employees can securely use public and enterprise AI agents such as Microsoft Copilot, develop with new AI coding agents such as Cursor, and leverage local agents with Model Context Protocol (MCP) servers. 

• Securing Private AI Applications and AI Agents: The Aim AI Firewall secures internal AI applications and agents against runtime AI attacks. It enforces corporate security and governance policies on all interactions between users, AI agents, and internal AI applications and models, whether on premises or in a cloud data center. 

• Securing the Agentic AI Development Lifecycle with AI Security Posture Management (AI-SPM): Aim secures the entire AI development lifecycle, from training ML models to building custom AI agents. Aim continuously discovers, detects, and remediates AI security and compliance risks before they reach production, and scans internal AI models for misconfigurations and vulnerabilities to enable customers to maintain optimal AI model security posture at all times. 

Aim’s research team underpins the company’s AI security solution and recently uncovered the first reported CVE of a zero-click AI vulnerability in Microsoft 365 Copilot, dubbed “EchoLeak” (CVE-2025-32711). 

“One of the world’s largest financial services companies deployed Aim to secure its AI adoption,” said Matan Getz, co-founder and CEO of Aim Security. “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.” 

Converging AI Security into Cato’s Industry-Leading SASE Platform

Cato has pioneered the SASE market by building the first cloud-native SASE platform architected from the ground up to secure all enterprise network flows from any source to any destination. Unlike proxy-based and appliance-based architectures, Cato has complete, 360-degree visibility into AI interactions—from users accessing AI applications to AI agents, models, MCP servers, and other API-driven services supporting AI-enabled workflows. 

Aim extends the Cato SASE Cloud Platform by unlocking a powerful set of AI security capabilities. These capabilities address the complexity and unstructured nature of AI interactions—as well as the evolving AI attack surface—to detect and stop threats, attacks, risky or anomalous access, and data breaches.

By converging Cato’s global visibility and policy enforcement capabilities, on-premises and in the cloud, with Aim AI security capabilities and expertise, Cato is now ready to secure customers’ AI transformation.

Your SASE Journey: Modular and Gradual Use Case Adoption

Cato supports a modular and gradual adoption of platform capabilities, with a simple license, across Network Modernization (SD-WAN), Security Consolidation (SSE), Hybrid Work (ZTNA), and now AI Security (AISEC).

Cato customers with current AI security requirements can deploy Aim today. 

As part of Cato’s commitment to delivering all capabilities through a single converged platform, Cato will offer Aim capabilities as part of the Cato SASE Cloud Platform in early 2026 and will offer a seamless migration path to all customers who deployed the standalone Aim solution.
