Pluto Security raises $42M as AI gives enterprise security teams a new headache

The problem with giving everyone in a company access to AI tools is that people will use them in unexpected ways. And that fact is steadily seeding fears that companies now have new, gaping security holes in their systems or, at least, will soon.

Illustrating the pace of AI tool adoption within enterprises driving such fears, Shahar Bahat, CEO and co-founder of Pluto Security, says a newly announced AI tool can show up inside companies’ environment within a mere two hours of its release. And about 60% of the risks her company detects across its customer base are in tools vibe-coded by non-developers: Finance departments are the biggest source of such risks, she told TechCrunch, followed by marketing and legal teams. Developers rank fourth, she said.

Her startup’s tools apparently found a vibe-coded app made by a finance employee at a Fortune 500 company to manage customer information and churn, but the app was left exposed to the internet.

Pluto, fresh out of stealth with $42 million in funding, is the latest in a new crop of security startups that have quickly sprung up to help companies address those fears gaps, and all of them are raising big money from investors on the back of the conviction that only using existing security software to monitor and control AI tools, connectors and usage is a square-peg-round-hole approach.

Bahat tells TechCrunch her startup started selling only in April, and has already found some takers for its tech, which helps companies gain context, risk analysis, visibility and control over how their employees use AI tools. She said Pluto began selling in April and has already crossed $2 million in annual recurring revenue, with more than 30 enterprise customers who include Oscar Health, Workato, Sixt and AlphaSense.

That’s decent traction for a young startup, though not unique in this AI era. But it may be because the breadth of the risk isn’t isolated to large tech companies that lead the AI adoption charts.
