CrowdStrike agrees to buy Fiddler and Dreadnode to watch and test AI agents, for about $495m combined, The Wall Street Journal reported

CrowdStrike said on 3 November that it has signed definitive agreements to acquire Fiddler, which monitors and explains what AI agents do, and Dreadnode, which tests AI models, applications and agents for security weaknesses before they are deployed.

Fiddler will be sold as Falcon Observe. Dreadnode's findings will feed CrowdStrike's Falcon Guardian runtime protection as policy recommendations. Both deals will be paid predominantly in cash, with some stock subject to vesting, and both are expected to close in CrowdStrike's fourth fiscal quarter of 2027. The releases, datelined Austin and Fal.Con Europe 2026 in Barcelona, give no prices.

The two deals come to about $495m, The Wall Street Journal reported, according to SiliconANGLE and IBTimes UK. IBTimes UK puts the split at about $400m for Fiddler and $95m for Dreadnode, citing the Journal.

George Kurtz, CrowdStrike's chief executive, said in the release: “Fiddler is the flight recorder for every agent: the observability to explain exactly what an agent did and why.”
