CrowdStrike has agreed to acquire two artificial intelligence security companies, Fiddler AI and Dreadnode, as it moves to control how autonomous AI agents are tested, watched and governed inside large organisations.
The cybersecurity group announced both deals on 3 November at its Fal.Con Europe conference in Barcelona. Fiddler AI makes observability software that records and explains what AI models and agents do once they are running inside a business. Dreadnode automates security testing, probing models, applications and agents for flaws before they are put into live use.
Together, the two purchases address opposite ends of the same problem. Companies are deploying agents that can take actions across their systems — moving data, triggering workflows and talking to other software — often faster than their security teams can keep track of them. Fiddler’s tools are meant to show what an agent did and why, while Dreadnode’s are meant to find weaknesses before deployment, rather than after a failure.
CrowdStrike plans to fold Fiddler into its Falcon platform as Falcon Observe, where it will help customers evaluate agents before launch, understand their actions in use and feed that activity back into the wider platform as telemetry. Dreadnode will be integrated into Falcon Guardian, with its testing results feeding in as security policy recommendations. CrowdStrike has also launched an AI Kill Switch, which lets security teams halt an agent that goes off course.
The price has not been confirmed by CrowdStrike. The Wall Street Journal reported that the company will pay about $400 million for Fiddler AI and about $95 million for Dreadnode, a combined $495 million, and that figure is the basis for the headline. Both deals are expected to close in CrowdStrike’s fourth quarter of fiscal 2027, subject to customary conditions, and are to be paid predominantly in cash, with a portion in stock subject to vesting.
The scale of the bet reflects how quickly agent security has become a contested market. Fiddler, founded in 2018 and based in Palo Alto, has raised about $99 million to date, according to PitchBook. Dreadnode, founded in 2023, has raised $14 million. Neither deal has closed yet, and the products are scheduled to become generally available in the same fiscal quarter as the expected closings.
