Palo Alto Networks to acquire Koi Security for $400M, targeting the emerging Agentic Endpoint attack surface.

Koi (Assaraf, Dardikman, Kruk) developed LLM-powered analysis to detect:
• Malicious extensions/plugins
• Package ecosystem abuse (NPM, Homebrew)
• AI agent exploit chaining
• Model artifact manipulation
• Credential hijacking within agent frameworks

Planned integration into Prisma AIRS™ and Cortex XDR® aims to improve AI runtime visibility and enforcement.

Question for defenders:
Are your telemetry pipelines mapping AI agent behavior - or just traditional executables?
