## History

Cato Networks was founded in 2015 in Tel Aviv, Israel, by Shlomo Kramer, co-founder of Checkpoint and Imperva, and Gur Shatz, a co-founder of networking company Incapsula.[2][4] Cato was initially funded with a $20 million Series A from U.S. Venture Partners and Aspect Ventures.[5] Kramer became CEO, and Shatz became president and COO.[1] It secured a Series B round of $50 million in September.[1] The company officially launched in February 2016.[6] Its first products were designed to protect customers' wide area network (WAN) connections and mobile devices with next-generation firewalling, URL filtering, application control, VPN access, and more services.[5]

In June 2018, the company added threat hunting capabilities to its networking service.[7] In 2019, the company secured a $55 million Series C funding round.[8] In April 2020, the company raised $77 million in a Series D.[1] In November, the company announced a $130 million Series E funding round, led by return investors Lightspeed Partners, with participation from Greylock Partners, U.S. Venture Partners, Aspect Capital, Singaporean fund Singtel's subsidiary Innov8, and hedge fund Coatue Management.[9] The investment reportedly valued the company at over $1 billion, making it a tech unicorn.[9]

In June 2021, the company launched a new version of its managed detection and response (MDR) platform, used to detect security threats on its network.[10] In October, the company announced it had raised $200 million at a $2.5 billion valuation.[8] The round was led by Lightspeed Venture Partners with the participation of existing investors Greylock, Acrew Capital, Coatue, Singtel Innov8, and CEO Kramer.[8] In February 2022, the company added cloud access security broker (CASB) capabilities to protect cloud applications.[11]

In September 2025, Cato Networks announced its first-ever M&A deal with the acquisition of Aim Security, an AI security startup based in Israel, in order to expand into the rapidly growing AI security segment.[12][13] Included in this announcement were two other recent developments: that it had crossed the $300 million Annual Recurring Revenue (ARR) threshold; and that it had raised another $50 million in its Series G round, bringing the total to $409 million at an estimated valuation of over $4.8 billion.[14]
