In short
Pluto Security came out of stealth on 13 October 2026 with $42 million: an $8.5 million seed led by TLV Partners and a $34 million Series A led by Jump Capital. It monitors the AI tools and agents employees use and can intervene when an agent acts beyond what the user intended.
The funding
Pluto Security came out of stealth on 13 October 2026 with $42 million in total, TechCrunch reports: an $8.5 million seed round led by TLV Partners and a $34 million Series A led by Jump Capital.1 Skinos, the fund of Check Point co-founder Shlomo Kramer, Ansa Capital and Armis’ founders also took part.1 Shahar Bahat is chief executive and co-founder.1
What it does
Pluto watches the AI tools employees use at work and the parts they are built from: skills, extensions, MCP servers (connectors that let AI tools reach other apps), and the apps and agents staff build themselves.12 It flags risky components, spots potentially dangerous agent behaviour and enforces company rules without blocking people from using AI.1
It can also step in during a task, for example stopping an agent that asks for more permissions than the user intended, or making it ask for confirmation.1 Pluto’s site lists uses such as blocking risky skills, requiring approval before an agent can use a payment API, and allowing only trusted MCP servers.2
“We’re moving from user behavior to agent behavior,” Bahat told TechCrunch.1
A free tool too
Pluto runs Plutonium, a free catalogue where anyone can look up the risk of public AI connectors, plug-ins and skills.12
Customers and traction
Pluto says it began selling in April and now has more than $2 million in annual recurring revenue and over 30 enterprise customers, including Oscar Health, Workato, Sixt and AlphaSense.12 These are the company’s own figures.
Why it matters
As staff build their own AI tools and connect agents to company data, security teams need to see what those agents can reach. Pluto says about 60% of the risks it finds are in tools built by non-developers, with finance teams the largest source.1
