CrowdStrike agrees to buy AI agent firms Fiddler and Dreadnode, reportedly for a combined $495 million
The deals add agent observability and automated AI security testing to the Falcon platform. The Wall Street Journal put the prices at about $400 million and $95 million.
CrowdStrike announced on Tuesday that it has agreed to acquire Fiddler AI, which monitors AI agents, and Dreadnode, which does AI security testing. CrowdStrike did not disclose the terms. The Wall Street Journal, which reported the deals before they were announced, said CrowdStrike is paying about $400 million for Fiddler and about $95 million for Dreadnode, roughly $495 million in total. CrowdStrike said both deals will be paid mostly in cash, with some stock subject to vesting conditions. They are expected to close in the fourth quarter of its fiscal year 2027, which ends January 31, 2027. Fiddler was founded in 2018 and is based in Palo Alto, California. In January it raised a $30 million Series C, bringing its total funding to $100 million. Its technology monitors AI agents and explains their decisions. CrowdStrike says Fiddler will add pre-deployment testing of agents, tracing of their reasoning and tool calls, detection of behavioral drift and hallucinations in production, and logging of agent activity for compliance. Dreadnode will add automated security testing of AI systems to the Falcon platform. The purchases reflect the security industry's push to treat autonomous agents inside companies as something to watch, test and control.
