CrowdStrike Acquires AI Security Firms Fiddler and Dreadnode to Bolster Platform
CrowdStrike announced its intent to acquire AI security specialists Fiddler AI and Dreadnode, aiming to integrate advanced AI observability and automated testing into its Falcon platform.
CrowdStrike has announced its intention to acquire two artificial intelligence security companies, Fiddler AI and Dreadnode, bolstering its existing Falcon platform with enhanced AI observability and automated security testing capabilities. The acquisitions, revealed at the company's Fal.Con Europe conference, aim to address the growing security challenges associated with the rapid adoption of AI agents.
Fiddler AI specializes in providing AI agent observability and explainability, functioning as a critical "flight recorder" for AI decision-making processes. Its technology will be integrated into CrowdStrike's Falcon platform as Falcon Observe. This capability is crucial for understanding how AI agents arrive at their conclusions, especially when they deviate from expected behavior, ignore instructions, or generate inaccurate information. Fiddler's system traces decisions across agent frameworks like LangGraph, Amazon Bedrock, and Google ADK, providing auditable records and flagging drifting behavior.
Dreadnode, on the other hand, focuses on the proactive security testing of AI systems. Its platform automates the identification of vulnerabilities in AI models and agents before they are deployed into production. Dreadnode employs over 100 known attack methods, including jailbreaks and prompt injection techniques, to uncover weaknesses. It then ranks these issues by severity and maps them to industry standards such as the OWASP Top 10 for LLMs and the NIST AI Risk Management Framework.
These acquisitions come at a time when traditional security testing methods are proving insufficient for the unique complexities of AI. AI agents, while potentially holding valid credentials and approved tools, can exhibit unpredictable behavior that falls outside the scope of conventional code-based security analysis. The ability to observe and test AI at the model and reasoning layers is becoming paramount for safe and controlled AI deployment.
In conjunction with these acquisitions, CrowdStrike also introduced new capabilities for its Falcon Guardian product, designed to protect AI agents during runtime. Notably, CEO George Kurtz unveiled the "AI Kill Switch," a control mechanism designed to allow human operators to halt any AI agent immediately. Kurtz emphasized that this control, operating outside the AI model itself, provides a crucial safety net, enabling organizations to deploy AI more confidently and at greater speed.
CrowdStrike frames these advancements as a shift from traditional "security" to broader "safety." While security has historically focused on preventing external threats, the company argues that AI safety involves ensuring AI can operate effectively and reliably within business operations, with human oversight. The AI Kill Switch is presented as a key enabler of this transition, allowing for faster AI deployment by mitigating the risks associated with potential AI misbehavior.
Both Fiddler AI and Dreadnode are expected to become generally available within CrowdStrike's fourth quarter of fiscal year 2027. The financial terms of the deals were not disclosed, though a report from The Wall Street Journal indicated Fiddler was valued at $400 million and Dreadnode at $95 million. The transactions are expected to close in the same quarter, subject to regulatory approvals, and will be paid primarily in cash with a portion in CrowdStrike stock.
