Palo Alto Networks in talks to buy AI agent security startup Clutch for $500M

Palo Alto Networks negotiates acquisition of AI security startup Clutch for $500M.

“Clutch, backed by Lightspeed and SignalFire, was last valued at $85 million, according to a source.”
— TechCrunch

Why it matters

Palo Alto is betting that agent behavior itself becomes a security surface—a new attack vector as autonomous systems gain permissions. This acquisition signals that enterprise security now requires monitoring and controlling AI agent actions, not just infrastructure access.
