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

Pluto Security has secured $42M in funding to address a growing problem: as enterprises roll out AI tools broadly, employees use them in ways IT and security teams did not anticipate, opening potential gaps in corporate defenses.

The core concern is that generative AI assistants, when given broad access, can be prompted to exfiltrate data, bypass internal controls, or interact with systems in unintended ways. Security teams are racing to understand the blast radius of these tools before incidents occur.

This funding round signals that AI-driven security risk is becoming a distinct market category. Vendors are positioning themselves at the intersection of AI governance and traditional cybersecurity, a space that is still largely uncharted.

For enterprises, the takeaway is that AI deployment without corresponding security guardrails may create liabilities that outpace the productivity gains. The market for solutions in this area is likely to grow as more organizations adopt AI tools at scale.
