CrowdStrike launches AI agent kill switch, plans to acquire Fiddler

CrowdStrike launched an AI Kill Switch within Falcon Guardian that can terminate unauthorized AI agents in real time through its gateway and block them from re-running across the organization. The company also said its AI Gateway is now generally available, centralizing inspection of prompts and responses, usage monitoring, and security policy enforcement. CrowdStrike plans to acquire Fiddler AI to strengthen agent observability, using its technology to evaluate agents before deployment and explain their actions. The kill switch will later extend to terminating agents on endpoint devices. The moves matter because they give enterprises runtime control and auditability over autonomous AI agents, a fast-growing attack surface. Next, watch whether the Fiddler deal closes and how quickly endpoint-level termination ships.
