CrowdStrike Launches AI Agent 'Kill Switch,' Plans to Acquire Fiddler AI

In brief

• CrowdStrike has launched an AI Kill Switch that lets security administrators block unauthorized AI agents through a gateway, with direct endpoint termination planned for later.
• The cybersecurity company signed an agreement to acquire Fiddler AI, reportedly for about $400 million, to monitor agent behavior and explain automated decisions.
• The combined technology aims to give enterprises more control over AI agents that can access corporate systems and take actions without constant human supervision.

CrowdStrike has introduced an AI agent kill switch designed to stop unauthorized activity inside corporate networks, alongside plans to acquire AI observability startup Fiddler as businesses give increasingly autonomous software access to their systems.

The cybersecurity company announced the launch Tuesday at its Fal.Con Europe 2026 conference in Barcelona, expanding its Falcon Guardian security platform with controls that let administrators intervene when AI agents stray beyond their assigned tasks.

The move tackles a problem companies face as they deploy AI systems capable of executing code, accessing sensitive information, and interacting with business applications. Unlike conventional chatbots, these agents can perform sequences of actions with limited human oversight, potentially causing damage even when nobody has deliberately attacked them.
