CrowdStrike Boosts AI Security with Fiddler, Dreadnode Acquisitions
CrowdStrike announced its acquisition of Fiddler AI and Dreadnode, two AI security startups, at its Fal.Con Europe conference. These deals aim to integrate AI agent observability and proactive AI security testing into CrowdStrike's Falcon platform, with products expected in Q4 FY2027. Concurrently, CrowdStrike launched its AI Kill Switch for immediate deployment against rogue AI agents, available today.
BARCELONA – Cybersecurity giant CrowdStrike announced on Tuesday its agreement to acquire two pivotal AI security startups, Fiddler AI and Dreadnode, significantly expanding its capabilities in AI governance and defense. The news, unveiled at the company's Fal.Con Europe conference, comes alongside the immediate launch of CrowdStrike's AI Kill Switch, a critical new feature designed to neutralize rogue AI agents.
These strategic moves underscore CrowdStrike's aggressive push to secure the burgeoning landscape of artificial intelligence, providing enterprises with essential tools for observability, proactive testing, and rapid response. While financial terms of the acquisitions were not disclosed, CrowdStrike indicated that payments would be primarily in cash, supplemented by stock with vesting conditions. Both deals are anticipated to finalize in the fourth quarter of CrowdStrike’s fiscal year 2027, pending customary closing conditions.
Bolstering AI Observability and Trust
The acquisition of Fiddler AI will integrate its advanced capabilities into CrowdStrike’s Falcon platform as Falcon Observe, slated for release in Q4 FY2027. Fiddler specializes in tracking the actions and underlying reasoning of AI agents, offering unparalleled visibility into their operations. This functionality is crucial for organizations needing to understand and justify their AI systems' behavior, particularly in regulated environments.
CrowdStrike founder and CEO George Kurtz emphasized the necessity of Fiddler's technology, stating, “When a regulator or your board asks what an agent did, saying ‘the model did it’ is not an answer.” He likened Fiddler to a “flight recorder for every agent,” providing the observability to precisely explain an agent’s actions and ensure adherence to its designated tasks. Fiddler’s models are also noted for their efficiency, capable of reducing evaluation costs by up to 98 percent. Krishna Gade, Fiddler’s chief executive, highlighted the core mission: “can I trust what my AI agents are doing?”
Proactive Defense Against AI Threats
Dreadnode’s acquisition positions CrowdStrike at the forefront of proactive AI security testing. Dreadnode develops sophisticated methods to identify vulnerabilities in AI models, applications, and agents before they are deployed. Its platform executes over 100 known AI attack strategies, including advanced jailbreaks and prompt injection techniques, to rigorously test systems.
The findings from Dreadnode’s assessments are meticulously mapped to industry-standard frameworks such as the OWASP Top 10 for large language models, MITRE ATLAS, and NIST’s AI Risk Management Framework. Dreadnode’s team will join CrowdStrike’s elite Cyber Superintelligence Lab, integrating their expertise to further enhance the Falcon platform’s defensive capabilities. Brad Palm, Dreadnode’s chief executive, noted that “AI fails in ways traditional testing was never designed to catch,” underscoring the need for attacker-minded testing to uncover these unique vulnerabilities.
Immediate Control: The AI Kill Switch
Beyond the acquisitions, CrowdStrike also launched its AI Kill Switch, a significant addition to its Falcon Guardian AI security product, available immediately. This feature empowers defenders to instantly stop a rogue AI agent, block its re-launch, and sever its access to the company network. Activated by an authorized administrator, every action taken by the kill switch is logged for auditing purposes.
Initially, the sensor will halt agents at the gateway, with endpoint capabilities expected in the near future. Rick Orloff, CISO at Everpure, a CrowdStrike customer, praised the new feature, remarking, “If one goes off course, the AI Kill Switch gives our security team the final say.”
Expanding the AI Security Ecosystem
The announcements from Barcelona also included further integrations and partnerships. CrowdStrike is bringing Falcon Guardian inside Anthropic’s Claude Cowork, with the Falcon sensor operating within the virtual machine where Cowork’s agents execute code. This integration is currently in beta for macOS users, with Windows support anticipated by the end of November.
CrowdStrike's Fal.Con Europe conference has been a hub of activity, with earlier announcements including security collaborations with Dell for its AI Factory with Nvidia, as well as with Dynatrace and CoreWeave. Additionally, 15 partners, including major European telecommunication providers like BT and Deutsche Telekom Security, have joined Project QuiltWorks, a program leveraging frontier AI models to identify and remediate security risks. These developments follow recent moves like integrating OpenAI into its product and launching multi-agent investigations in September, and linking South Korean bank breaches to AI tools in October, signaling CrowdStrike’s comprehensive strategy to lead in AI security.
