Cato Networks has raised $359 million in a Series G funding round, pushing its valuation past $4.8 billion and total funding over $1 billion. Led by Vitruvian Partners and ION Crossover Partners, with continued support from Lightspeed and others, the investment reinforces Cato’s position as a leader in Secure Access Service Edge (SASE)—a market it helped pioneer in 2015.
Cato’s fully converged, cloud-native platform unifies security and networking, serving over 3,500 enterprise customers. With 46% year-over-year growth in recurring revenue, it significantly outpaces the broader SASE market, projected to grow at 26% annually through 2028.
The company plans to expand its AI-driven capabilities, invest in R&D, and grow its global presence. Unlike legacy vendors offering bundles of point solutions, Cato delivers an integrated platform that simplifies infrastructure, automates routine tasks, and enables secure adoption of AI technologies across the enterprise.
This funding marks a strategic inflection point, as Cato aims to redefine enterprise security for the AI era with a scalable, efficient, and unified operating model.
