CrowdStrike will acquire two AI security startups, Fiddler AI and Dreadnode, for a combined figure of nearly $500 million, according to TechCrunch, which reported the deals on Tuesday, November 3, 2026. TechCrunch says CrowdStrike announced both acquisitions in a blog post and attributes the prices to The Wall Street Journal.

The two companies

  • Fiddler AI: makes observability software for monitoring AI agents inside enterprises. The Wall Street Journal put the price at about $400 million. Fiddler was founded in 2018 and has raised about $99 million in total, per PitchBook as cited by TechCrunch. It will become part of CrowdStrike’s Falcon platform as “Falcon Observe.”
  • Dreadnode: helps companies automate security testing that looks for flaws in AI models, applications and agents before they go live. The Wall Street Journal put the price at about $95 million. Dreadnode was founded in 2023 and has raised $14 million to date. It will be integrated into CrowdStrike’s Falcon Guardian, with its testing results feeding security policy recommendations.

Figures and terms

TechCrunch’s headline refers to “nearly $500M” for the two companies; the two reported prices add up to about $495 million. TechCrunch’s article does not say whether the payment is in cash or stock or when the deals are expected to close, and it quotes no executives.

Market context in the report

TechCrunch says companies’ adoption of AI is outpacing their policies and processes, with employees using AI tools and vibe-coding apps and deploying AI agents, and it describes AI security as a “quickly burgeoning market.” It says Falcon Guardian provides detection and response controls for AI agents on devices, and that other startups and vendors in the field are raising funding in the tens of millions of dollars.
