Pluto Security closes $42M to secure enterprise AI agents

Pluto Security has completed a $42 million funding round, bringing its total raised to the same figure as the startup disclosed when it emerged from stealth last October. The company secures AI agents built by enterprise employees, claiming over 1 million endpoints and dozens of enterprise customers.

The round was led by Jump Capital and TLV Partners, with participation from Ansa Capital and a group of angel investors. MSN first reported the investor list last year, and Pluto’s own announcement now confirms the total funding amount.

When we covered Pluto’s stealth exit on 13 October, the company had already raised the same $42 million, suggesting the new announcement formalizes the earlier round rather than marking a fresh infusion. The startup joins a growing cohort of well-funded players in the AI agent security space, including Island’s $400 million round at a $6.4 billion valuation, Reco’s $55 million raise, and Rig Security’s $12 million seed.

Pluto’s focus on employee-built AI agents distinguishes it from competitors targeting AI agents that operate inside enterprise browsers or networks. The distinction may matter less as the market matures; what remains open is whether enterprises will adopt multiple point solutions or consolidate around a single platform. The funding surge suggests investors are betting on the latter.
