Pluto Security emerges from stealth with $42 million in funding

Pluto Security has disclosed $42 million in funding as it emerges from stealth, targeting security risks associated with employees’ use of artificial intelligence tools. The company said the money will support product development, security research and expansion of its U.S. presence.

Its financing includes a seed investment of $8.5 million, with TLV Partners as lead investor and participation from Armis’ founders. Jump Capital led a recent $34 million Series A, joined by Ansa Capital, angel investors and Skinos, the venture firm of Check Point co-founder Shlomo Kramer.

CEO and co-founder Shahar Bahat said Pluto began sales in April and has surpassed $2 million in annual recurring revenue. Its more than 30 enterprise customers include Oscar Health, Workato, Sixt and AlphaSense. The company employs 40 people across the U.S. and Israel.

Bahat said about 60% of the risks Pluto identifies among customers involve AI-coded tools built by non-developers. Finance teams account for the largest share of those risks, followed by marketing and legal, she said. Pluto says its software tracks employees’ AI tools and the components, applications and agents associated with them, and can intervene to block risky actions or request confirmation.

Pluto also introduced Plutonium in April, a free service for checking publicly available AI components for security risks. Bahat said thousands of security professionals use the platform and that inbound interest accounts for 70% of Pluto’s sales pipeline, without specifying how much originates from Plutonium.
