Pluto Security comes out of stealth with $42m for AI agent security

13 October 2026: Pluto Security, which builds security software for the AI agents, coding tools and plug-ins employees now install on their own, has come out of stealth with 42 million dollars in funding. The company says it already secures more than 1.5 million endpoints at enterprise customers, including several Fortune 500 companies, a year after it started.

Not yet independently verified. Pluto Security states the 42 million dollar total but not the rounds, the investors or its headquarters; the split into a seed led by TLV Partners and a Series A led by Jump Capital, and the Tel Aviv base, come from one outlet. We will update this when it can be confirmed, and remove this note.

How the money was raised

Pluto's own announcement gives the total and nothing else. SiliconANGLE reports that about a fifth of it was a seed round led by TLV Partners and the rest a Series A led by Jump Capital, with Skinos also investing. The company says its team is spread across Israel and the US; the same outlet places its headquarters in Tel Aviv.

The announcement, written by founder Shahar Bahat, does not say what the money will be spent on beyond growing the team and the product.

What the product does

Pluto's starting point is that ordinary employees have become builders. Staff connect AI agents to company data, install coding assistants and browser extensions, and wire up MCP servers, the connectors that let a model call outside tools, often without the security team knowing. Pluto sits on the endpoint, finds those tools and controls what they can reach, so a company can allow them rather than ban them. Bahat describes the aim as ending security's role as "the department of NO".

The company also publishes research. In September its researchers reported finding 179 MCP server deployments exposed on the internet, 147 of which accepted requests with no authentication, and it runs an open-source toolkit called Plutonium.

Its own figures

Pluto says it reached multi-million-dollar annual recurring revenue within its first year and that some leading AI companies use it to secure their own environments. It does not name customers or give a revenue figure. An analyst report from Latio this year listed Pluto as an endpoint AI security vendor, according to the company.

Questions for a trial

Buyers comparing Pluto with endpoint and browser security tools that add similar controls should ask whether a product discovers tools on the device itself or only through network traffic, and whether it can block an MCP server or extension rather than just report it.
