About Pluto Security

Pluto Security sells security for what people build with AI. Pluto Security says it protects modern creation workflows, across AI builders, developer tools, and business workspaces, with visibility, risk understanding, and real-time guardrails.

Pluto Security describes the problem as one that security teams face when AI tools let everyone build fast. Its about page says security teams were forced to either block everything or accept the risk, and that Pluto offers a third way: let people build, while security stays in control. Its homepage says new tools, skills, plugins and extensions, combined with intent-based actions that execute in runtime, lead CISOs to either block or approve in bulk.[3]

The homepage names four problem areas.

Pluto Security says it protects every layer of the AI atmosphere: tools, supply chain, artifacts and runtime. Its homepage describes four connected capabilities: uncovering an organization's AI universe with wide context, triaging every discovery with Pluto's self-research risk database, enforcement through intent-based policies that adapt in real time, and a place for every safe, verified AI add-on that is curated by default.[1][3]

The homepage gives examples of use cases by team. Finance runs scripts with Cursor and approval is required for payment API access. For AI builders connecting MCP servers, trusted MCPs are allowed and the rest are quarantined. HR builds with Lovable while employee and company data is protected, and Sales uses AI agents for prospecting while unauthorized outbound actions are prevented.[3]

Pluto Security states that it offers visibility and risk understanding for AI-driven building activity, allowing security teams to monitor real-time guardrails across AI workflows and integrations.[4]

On company facts, Pluto says it is officially out of stealth, with $42 million in total funding. Pluto Security was founded by a team from Unit 8200, Microsoft, and Palo Alto Networks. Its about page says it is part of accelerators including AWS, CrowdStrike and NVIDIA.[1][3][5]
