Cato Networks, a leading secure access service edge provider, has raised fresh capital to advance its position in the cybersecurity market. The company, recognised for redefining enterprise security, continues to push boundaries in AI-powered networking.
The company has secured $359m in a Series G round led by Vitruvian Partners and ION Crossover Partners. Existing backers Lightspeed Venture Partners, Acrew Capital and Adams Street Partners also participated. The new round lifts Cato’s total funding to over $1bn and values the business at more than $4.8bn.
Cato Networks is known for pioneering SASE—a cloud-native platform that merges security and networking. Since introducing the concept in 2015, the company has been at the forefront of transforming how enterprises manage and protect their digital operations, especially in the age of AI.
The latest funds will help Cato Networks strengthen its AI security capabilities, ramp up research and development, and expand globally. Key areas of focus include enhancing tools for digital experience monitoring, LAN security, IoT/OT protection, SD-WAN, SSE, XDR, and zero trust network access—all built natively into its single platform.
Cato said it plans to grow its global partner ecosystem and customer teams to meet the rising demand for unified security and networking solutions. The company believes its platform, which replaces fragmented legacy infrastructure, gives organisations a more agile and resilient way to protect data and operations.
“With more than 3,500 enterprise customers, consistent hyper-growth, and repetitive and scalable wins against all leading competitors, Cato is a proven and mature business to invest in,” Cato Networks CEO Shlomo Kramer said. “Our true SASE platform and decade of AI innovation differentiates Cato from legacy vendors that favor a portfolio of point solutions. Customers and partners understand the difference and select Cato to benefit from proven security, operational efficiency, and business agility.”
Vitruvian Partners said, “Cato has spent the past decade building and optimizing the next generation of cybersecurity, and we are proud to partner with them as they continue to raise the bar for AI-driven security and networking. The company’s visionary leadership, best-in-class growth and retention rates, and relentless focus on innovation and customer experience are what led us to invest in Cato. We look forward to supporting Cato’s next phase of growth as they expand their market reach and transform how enterprises connect and secure their digital businesses and use of AI.”
Ravi Mhatre, partner and co-founder at Lightspeed Venture Partners, added, “As a longtime investor in Cato Networks, we’ve had a front-row seat to its incredible journey, from defining the SASE category to leading it. Cato is reshaping enterprise security with a unified, AI-powered SASE platform that’s secure, scalable, and built for the cloud-first world. They’re not just eliminating IT complexity. They’re unlocking real agility for the digital business. We’re proud to further support Cato as they continue setting the standard for SASE leadership.”
The fresh capital brings Cato’s total funds raised to more than $1bn since inception, underlining the company’s growth momentum and investor confidence as it continues to expand its footprint in the global cybersecurity and networking market.
