$495 Million AI Security
CrowdStrike agreed to acquire Fiddler AI for approximately $400 million and Dreadnode for about $95 million, for a combined $495 million, as the company expanded its Falcon platform to cover AI agent observability and automated security testing. CrowdStrike planned to integrate Fiddler AI into Falcon Observe, where the platform would trace AI agents’ decisions, monitor execution behavior, and log activities for compliance. CrowdStrike planned to integrate Dreadnode into Falcon Guardian so the testing results would feed into policy recommendations for weaknesses discovered before deployment.
CrowdStrike expected both acquisitions to close in its fiscal fourth quarter of 2027, subject to customary closing conditions, and expected the related capabilities to be generally available in that same quarter. George Kurtz described Fiddler as “the flight recorder for every agent,” framing the observability and explainability effort as a way to answer what an agent did when a regulator or board asks.
Testing, Frameworks, and Kill Switch
Dreadnode’s automated security testing platform ran more than 100 known attack strategies, including jailbreak attempts and prompt injection, to identify vulnerabilities in models, applications, agent reasoning loops, and Model Context Protocol (MCP) servers. CrowdStrike said Dreadnode would map findings to security frameworks including the OWASP Top 10 for LLMs, OWASP Agentic Security (ASI01-ASI10), MITRE ATLAS, and the NIST AI Risk Management Framework. CrowdStrike also introduced an AI Kill Switch within Falcon Guardian, giving authorized security administrators the ability to intervene when autonomous agents deviate from their intended behavior.
CrowdStrike described the Kill Switch as a control that enables defenders to terminate an agent, block its relaunch on specified systems, and remove its access to the corporate network. George Kurtz wrote on X that the switch “lives outside the model, at runtime, where an agent can’t argue with it, rewrite it, or wait it out.”
Falcon Rollout and Investor Watch
CrowdStrike said it would integrate Fiddler’s observability and explainability capabilities into Falcon Observe, and it would connect Dreadnode’s pre-deployment testing results with Falcon Guardian so identified weaknesses could inform security policies in real time. CrowdStrike said the platform would assess agent accuracy and policy compliance before deployment, track decisions and tool calls during operation, and identify behavioral deviations, hallucinations, and undesired actions. CrowdStrike expected automated AI security testing to become generally available in the fourth quarter of fiscal 2027, and it expected the acquisitions to close during that same quarter, subject to customary closing conditions.
CrowdStrike said the Kill Switch was already available, while the acquired technologies had not yet been fully integrated. Investors were directed to watch the integration progress and whether Falcon Observe and Dreadnode’s testing capabilities translate into new client onboarding and future revenue growth, as TradingKey tied the announcements to CrowdStrike’s AI security expansion and the AI Kill Switch rollout.
