Pluto Security Raises $42M to Secure Enterprise AI Tools
Pluto Security raised $42M Series A led by Jump Capital to provide visibility and control over employee AI tool usage.
The big picture: Pluto Security, emerging from stealth with $42 million in funding, is addressing the growing security risks posed by the rapid adoption of AI tools within enterprises. The company’s platform provides visibility, risk analysis, and control over how employees use AI, aiming to close new security gaps. Pluto Security has already secured over 30 enterprise customers, including Oscar Health and Workato.
Why it matters:
- Rapid adoption: New AI tools can appear in enterprise environments within two hours of release, creating immediate and often unmonitored security vulnerabilities.
- Non-developer risks: Approximately 60% of AI-related security risks detected by Pluto originate from non-developer departments like finance, marketing, and legal, highlighting a broad organizational exposure.
- Inadequate existing solutions: Current enterprise security software is proving insufficient for monitoring and controlling the complex interactions of AI tools, agents, and their components, necessitating specialized solutions.
How it works:
- Real-time monitoring: Pluto’s software tracks AI tools, skills, extensions, and agents used by employees, identifying risky components and potentially dangerous activity in real time.
- Proactive intervention: The system can intervene during an agent’s operation, stopping actions that exceed user-intended permissions or prompting for confirmation to prevent unauthorized activity.
- Context injection: Pluto can inject context back into AI sessions, allowing it to modify agent behavior and enforce security policies without completely blocking employee access to AI tools.
The catch: The AI security market is rapidly attracting significant investment and new entrants, indicating a crowded and competitive landscape. While Pluto’s early traction and inbound sales pipeline are strong, sustaining this growth will require continuous innovation and effective differentiation amidst a proliferation of similar solutions.
