Palo Alto Networks to Acquire Koi to Police AI Agents on Endpoints

The company aims to bring Koi’s agent-focused controls into Prisma AIRS to boost Cortex XDR visibility on AI activity.

Overview

  • Palo Alto Networks announced a definitive agreement to buy Koi, positioning the combined technology to address risks from AI agents operating on enterprise endpoints.
  • Financial terms were not disclosed by the companies, though Israeli outlets reported an estimated price of about $400 million.
  • The plan calls for Koi’s capabilities to extend Palo Alto’s Prisma AIRS platform and to enhance Cortex XDR with greater insight into the AI attack surface and improved policy enforcement.
  • The companies frame the approach as Agentic Endpoint Security, asserting that AI agents, plugins and scripts act like privileged insiders beyond traditional file-centric defenses.
  • The transaction is subject to customary closing conditions and potential regulatory review, reflecting a broader consolidation trend in AI-focused cybersecurity.
