Pluto Security

Pluto Security is a company that secures how employees use AI at work. It came out of stealth on 13 October 2026 with $42 million in funding, according to a post by its founder Shahar Bahat. The post says the company was only an idea a year earlier, and that it now protects more than 1.5 million endpoints for enterprise customers.

What it does

The company's focus is the growing set of AI agents, coding tools, MCP servers, browser extensions and custom workflows that staff adopt, often before security teams have reviewed them. Its site describes protection across tools, the AI supply chain, generated artifacts and runtime behaviour, with a stress on enforcement at the endpoint.

The platform is described in several parts. Explorer discovers the AI tools in use. Risk Radar triages what is found against the company's own risk research. Space Shield applies intent-based policies in real time, for example blocking an unauthorised action, requiring approval for access to a payment API, or allowing trusted MCP servers while quarantining others. Marketspace offers a curated collection of vetted AI add-ons. Plutonium is a free catalogue where anyone can look up connectors, plugins and skills and see their risk. Pluto also publishes vulnerability research.

Who it serves

The buyers are security leaders, particularly chief information security officers, in large organisations. Pluto says its customers include several Fortune 500 companies and some leading AI companies. Its site lists Guesty, SIXT, AlphaSense, Pennylane, Agoda, Redis, Riskified, Workato and Playtika among others it works with.
