CrowdStrike announces intent to acquire AI observability company Fiddler and AI security testing company Dreadnode
On 3 November 2026, cybersecurity company CrowdStrike announced its intent to acquire two AI companies: Fiddler, which it describes as a leader in AI observability, and Dreadnode, which tests AI models, applications and agents against known attack techniques before deployment. The announcements, made at CrowdStrike’s Fal.Con EU 2026 event, refer to closing conditions that must be satisfied but do not list them. CrowdStrike did not disclose terms.
What CrowdStrike announced about Fiddler and Dreadnode
CrowdStrike says Fiddler’s technology compares prompts, models and configurations to evaluate whether agents perform intended tasks safely and accurately before they reach production, and traces agent decisions and reasoning after deployment to detect behavioral drift and unintended actions. CrowdStrike plans to make it part of its Falcon platform as Falcon Observe, which it says “evaluates and explains whether agents behave as intended.”
CrowdStrike says Dreadnode runs more than 50 attack techniques, including jailbreaks, prompt injection, and multi-turn and agent-specific attacks, ranks findings by severity, and maps them to the OWASP Top 10 for LLMs, OWASP Agentic Security (ASI01 to ASI10), MITRE ATLAS and the NIST AI Risk Management Framework. CrowdStrike says Dreadnode’s results will feed into its Falcon Guardian product as policy recommendations for runtime protection.
CrowdStrike says it expects both capabilities to be generally available in the fourth quarter of its 2027 fiscal year. That is a product date, not a closing date; neither announcement gives an expected close. TechCrunch, citing The Wall Street Journal, reported prices of about USD 400 million for Fiddler and about USD 95 million for Dreadnode. CrowdStrike’s announcements do not state a price.
Why the CrowdStrike deals matter for AI assurance buyers
The AI assurance Learn page lists Fiddler as a representative observability and monitoring tool; Dreadnode’s work falls in evaluation and red-teaming. If completed, the deals would extend a pattern that page describes: AI security and testing tools being bought by major security vendors (Cisco with Robust Intelligence, Check Point with Lakera, Palo Alto Networks with Protect AI) and, in 2026, by model developers and AI application companies (OpenAI’s agreement to acquire Promptfoo; Harvey’s acquisition of Guardrails AI). The consolidation is tracked on the AI Risk Timeline.
If the deals complete, for organizations that use either tool, and for insurers and auditors that rely on its output as evidence, a change of owner can affect roadmaps, licensing, integrations with other vendors and the perceived independence of the testing or monitoring.
What CrowdStrike has not yet said
The announcements do not say when the acquisitions are expected to close, whether Fiddler and Dreadnode will remain available to customers that do not use the Falcon platform, or what will happen to existing customer contracts.
