Israeli AI Security Firm Pluto Security Raises $42 Million

Pluto Security, an Israeli cybersecurity firm specializing in AI security, has announced a total funding round of $42 million. The latest investment round, amounting to approximately $34 million, was led by Jump Capital, with participation from Skinos Ventures, founded by Shlomo Kramer, and AlphaDrive Ventures. An earlier seed round was led by TLV Partners, with investment from Ansa Capital.

The company's platform is designed to secure AI tools within organizations and the applications employees build using them. It analyzes actions and associated risks in these environments, enabling real-time blocking of dangerous activities without disrupting workflow. Pluto Security was founded in 2025 by CEO Shahar Behat, CPO Tal Ofer Regev, and CTO Gil Maman. Behat previously held senior cybersecurity roles at Microsoft and Palo Alto Networks, Regev was VP of R&D at Palo Alto Networks, and Maman served in cyber R&D and security engineering within Unit 8200.

Pluto Security has achieved significant traction, reporting millions in annual recurring revenue (ARR) within six months of commercial activity and securing over a million endpoints globally. The company serves more than 40 enterprise clients, including Oscar Health, Workato, Sixt, and AlphaSense, as well as Fortune 500 companies. The newly raised funds will be allocated to further product development, research, and expansion into the U.S. market.

CEO Shahar Behat highlighted the evolving work landscape, noting that employees now use an average of 15 AI tools, alongside other applications and custom-built tools, creating a complex security challenge. She emphasized that Pluto's platform addresses this by securing three distinct layers of activity, a comprehensive approach she claims competitors do not match. "We are less than a year old with millions in revenue and 40 paying customers. This is a complete, single solution in the industry," Behat stated, adding that the company aims to increase sales five to sixfold. Pluto currently employs 50 people in Israel and the U.S., with plans for Behat to relocate to the U.S. soon.

Rona Segev, Founding Managing Partner at TLV Partners, commented on the company's innovative approach, stating, "From the beginning, it was clear that Pluto looks at a problem differently, one that is rapidly becoming a significant challenge for organizations." She added that as AI transforms how people work, security teams need precise tools to identify and intervene in risks without hindering innovation, a philosophy she sees deeply embedded in Pluto's DNA and reflected in its rapid growth.
