Israeli AI Security Startup Pluto Security Raises $42 Million

Pluto Security, an Israeli cybersecurity startup, has announced a total funding round of $42 million. The latest round, amounting to approximately $34 million, was led by Jump Capital, with participation from Shlomo Kramer's Skinos Ventures and AlphaDrive Ventures. The seed round was previously led by TLV Partners, with investment from Ansa Capital. Notable individual investors include Ariel Maislos, Yevgeny Dibrov, and Nadir Izrael, co-founders of Armis, as well as other prominent figures in the tech industry.

In just six months of commercial operation, Pluto Security has achieved millions in annual recurring revenue (ARR), securing over a million endpoints globally and serving more than 40 enterprise clients, including Oscar Health, Workato, Sixt, and AlphaSense, as well as Fortune 500 companies. The company's platform is designed to secure AI tools within organizations and the applications built by employees using these tools. It provides security teams with visibility into the organization's AI environment, from the AI tools employees use and their connected components to applications, agents, and automations they build.

The platform analyzes actions within this environment and their associated risks, 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 technological leadership roles in cyber R&D and security engineering in Unit 8200. The company currently employs over 40 people in Israel and the US.

The newly raised funds will be allocated to further product development, research, and expansion of operations in the United States. The company highlights the rapid adoption of AI tools by employees, who are increasingly building their own software and applications, creating new challenges for traditional security systems. Pluto's platform integrates endpoint data with real-time analysis of AI tools and actions, distinguishing legitimate use from risky behavior. This approach allows security teams to enforce policies without hindering innovation, as demonstrated by scenarios where malicious plugins are blocked while AI tool usage continues.

Pluto Security also invests in security research and community tools, such as Plutonium, which helps assess risks in AI tool components. This tool, based on Pluto's RisksDB risk database, is used by thousands of security professionals. The company emphasizes that the synergy between its product, research, and community engagement has led to inbound customer interest and accelerated product adoption. Investors noted Pluto's unique growth engine, driven by its community-focused approach and the proactive customer acquisition it generates.
