Pluto Security has raised $42 million in funding to tackle the emerging security risks posed by the rapid adoption of AI tools within enterprises. The startup, led by CEO Shahar Bahat, addresses the challenge that many non-developers—especially in finance, marketing, and legal departments—are creating AI-driven applications and workflows that often expose companies to new vulnerabilities. Pluto’s technology detects these risks by monitoring how employees use AI tools and the agents they build, aiming to give enterprises better context, risk analysis, and control without hindering productivity.

Since beginning sales in April 2026, Pluto has quickly gained traction, surpassing $2 million in annual recurring revenue and acquiring over 30 enterprise customers including Oscar Health, Workato, Sixt, and AlphaSense. The company's recent funding includes an $8.5 million seed round led by TLV Partners and a $34 million Series A round led by Jump Capital, with participation from notable cybersecurity figures and firms. Pluto's approach focuses on tracking AI agent behavior in real time and intervening when suspicious or unauthorized activities are detected, such as attempts to gain unapproved permissions during workflows.

Pluto’s system integrates with existing endpoint security and device management infrastructure, deploying sensors that collect various data points like commands, prompts, running processes, and user activity. This allows the platform to dynamically assess threats and, if necessary, block risky actions or prompt the AI agent to seek user confirmation before proceeding. The startup also launched Plutonium, a free platform that enables security professionals to assess publicly available AI components for risks, which has built a community that contributes to Pluto’s sales pipeline through inbound interest.

Looking ahead, Pluto plans to use the new capital to accelerate product development, enhance security research, and expand its market presence primarily in the U.S. With a team operating in both the U.S. and Israel, the company targets the growing need for specialized AI security tools as enterprises struggle to secure newly AI-enabled environments. Pluto Security exemplifies a wave of startups dedicated to bridging the gap between traditional cybersecurity measures and the complex risks introduced by AI adoption.
