The cybersecurity giant is buying two AI security startups to help enterprises watch, explain and stress-test their AI agents
CrowdStrike has agreed to buy two AI security startups, Fiddler AI and Dreadnode, for a reported combined $495 million.
The deals were reported on November 3, 2026. They mark CrowdStrike’s latest push into a corner of cybersecurity that barely existed a few years ago: securing the AI systems themselves, not just using AI to catch hackers.
What CrowdStrike is buying
Fiddler AI is based in Palo Alto and was founded in 2018. It focuses on observability and explainability for AI systems.
CrowdStrike CEO George Kurtz described Fiddler with a fitting aviation metaphor.
“Flight recorder for every agent.”
Fiddler’s technology is set to become a product called Falcon Observe. It is expected to be generally available in CrowdStrike’s Q4 FY27.
Dreadnode is the younger of the pair, founded in 2023. Its specialty is pre-deployment security testing. CrowdStrike says the startup will strengthen automated testing mapped to the OWASP, MITRE ATLAS and NIST frameworks.
The numbers behind the deal
CrowdStrike did not disclose a price when it announced the Fiddler acquisition. It separately confirmed the Dreadnode deal.
The combined figure is approximately $495 million, according to reporting on the transactions.
Fiddler is valued at roughly $400 million. That works out to about 4x the $100 million in total funding the company had raised.
Dreadnode is valued at about $95 million. That is roughly 6.8x its $14 million Series A.
Both deals are expected to close in CrowdStrike’s Q4 FY27. Payment will be predominantly in cash, with some stock components that vest over time.
Why AI agents are a security problem
These acquisitions also fit a broader pattern at CrowdStrike. The company recently introduced an “AI Kill Switch” feature aimed at strengthening AI safety protocols.
Taken together, the pieces sketch a full lifecycle. Dreadnode tests an agent before launch, Fiddler monitors it in production, and the kill switch shuts it down if things go sideways.
