CrowdStrike acquires Fiddler AI and Dreadnode and launches an emergency stop for SI agents
Prepared by Sintelligent with the help of SI. Published in SI: . Updated: .
Companies are gaining tools not only to observe and test agents in advance, but also to disable them immediately when their behaviour becomes dangerous.
Both deals were announced at the Fal.Con Europe conference and are expected to close in CrowdStrike's fiscal Q4 2027, subject to customary conditions. Fiddler tracks agents' actions and the reasons for their decisions; its technology will become part of Falcon Observe. Dreadnode tests models, applications, agents and MCP servers using more than 100 attack methods, including prompt injection; its team will join the Cyber Superintelligence Lab. CrowdStrike has also released AI Kill Switch in Falcon Guardian: an authorised administrator can stop an agent, prevent it from restarting and disconnect it from the corporate network, with every action logged. The feature is available now, while integration between Falcon Guardian and Claude Cowork virtual machines is in beta on macOS.
