A separate announcement detailed plans to acquire Dreadnode and add automated AI security testing to the Falcon platform before systems reach production. Both announcements came at Fal.Con EU 2026 and describe proposed acquisitions.

CrowdStrike targets general availability for Falcon Observe and Dreadnode in the fourth quarter of its 2027 fiscal year. The planned products address distinct controls: probing AI for weaknesses before release, evaluating whether agents perform their intended tasks, and monitoring their decisions after deployment. Before deployment, teams can use Fiddler to compare prompts, models and configurations when evaluating whether agents perform assigned tasks safely and accurately.

It reconstructs the decision process so teams can locate the step that caused a failure. That visibility addresses a gap in conventional security controls.
