CrowdStrike announced on 3 November 2026 that it will acquire AI agent observability firm Fiddler AI and AI security testing company Dreadnode, to extend the Falcon platform to monitoring, testing and controlling AI agents. The announcements were made at the Fal.Con Europe conference in Barcelona (cyberscoop.com). CrowdStrike has not disclosed financial terms, but the Wall Street Journal reportedly put the deals at about $400 million for Fiddler and about $95 million for Dreadnode, roughly $495 million combined (securityweek.com, cyberscoop.com, techcrunch.com). Payment is reportedly mostly cash, with a stock component that vests over time (securityweek.com, cyberscoop.com). Fiddler's technology will become Falcon Observe, and Dreadnode's testing results will feed Falcon Guardian (securityweek.com, techcrunch.com). CrowdStrike also introduced an AI Kill Switch in Falcon Guardian to halt misbehaving agents. This is vendor business and product news, not a vulnerability or an active threat. CrowdStrike's own pages list related same-day announcements, including protection for AI agents inside Claude Cowork (crowdstrike.com).
Detalhes técnicos
- Fiddler AI (founded 2018, Palo Alto, about $99 million raised) provides pre- and post-deployment observability for AI agents (securityweek.com, techcrunch.com). It traces reasoning and tool calls, and detects behavioral drift, hallucinations and fabricated work. It also offers compliance audit logging and token usage/spend tracking (securityweek.com, cyberscoop.com). Supported frameworks include LangGraph, Amazon Bedrock and Google ADK (cyberscoop.com). As Falcon Observe, it will feed telemetry into the broader Falcon detection platform (techcrunch.com).
- Dreadnode (founded 2023, about $14 million raised) runs more than 100 known AI attack techniques against models, agent reasoning loops, applications and MCP servers (securityweek.com, techcrunch.com). These include jailbreaks, prompt injection, and multi-turn and agent-specific attacks. Findings are mapped to the OWASP Top 10 for LLMs, MITRE ATLAS and the NIST AI Risk Management Framework (securityweek.com, cyberscoop.com). Results surface in Falcon Guardian as security policy recommendations (techcrunch.com). The team, led by CEO Brad Palm, will join CrowdStrike's Cyber Superintelligence Lab (securityweek.com).
- AI Kill Switch and new Falcon Guardian runtime protections: CEO George Kurtz described the Kill Switch as a control that sits outside the model at runtime and lets humans halt any agent, even one that resists (cyberscoop.com). The rationale is that agents can hold valid credentials and approved tools yet still make poor decisions, hallucinate completed work or ignore instructions, which code-focused testing does not catch (cyberscoop.com).
- Timing: closing is expected in Q4 of CrowdStrike's fiscal 2027, which ends 31 January 2027, subject to standard regulatory approvals (securityweek.com, cyberscoop.com). Dreadnode's testing capabilities are expected to be generally available in the same quarter (securityweek.com), and cyberscoop.com says the same for both products.
- Context: the deals follow other CrowdStrike acquisitions: SGNL ($740 million) and Seraphic ($420 million) in January, and Pangea in September 2025 (securityweek.com).
Relatos divergentes
- Price: the figures are not official. CrowdStrike gave no terms (crowdstrike.com, cyberscoop.com, securityweek.com); the $400M, $95M and $495M figures are attributed to the Wall Street Journal (securityweek.com, cyberscoop.com, techcrunch.com). Its headline rounds the total to about $500M (techcrunch.com).
- Naming: CrowdStrike's own pages refer to the target as "Fiddler" (crowdstrike.com), while the press uses "Fiddler AI". This appears to be the same company.

CrowdStrike Acquires Fiddler AI and Dreadnode for ~$500M to Bolster AI Agent Security
ler a análise desta fonte ocultar
CrowdStrike is acquiring two AI security startups, Fiddler AI and Dreadnode, for a combined ~$495 million, aiming to expand its Falcon platform's ability to monitor, test, and secure AI models and agents. The deal reportedly values Fiddler AI at about $400 million and Dreadnode at roughly $95 million, according to The Wall Street Journal. This move comes as enterprises rapidly adopt AI agents and tools faster than their security policies can adapt, creating new monitoring and governance challenges for security teams. Fiddler AI, founded in 2018 with about $99 million raised, provides observability software for AI agents and will become Falcon Observe, feeding telemetry into the Falcon platform. Dreadnode, founded in 2023 with $14 million raised, automates security testing to find flaws in AI models and agents before deployment, and will be folded into CrowdStrike's existing Falcon Guardian product, feeding its testing results as security policy recommendations.
Technical Details
Falcon Observe (from Fiddler AI) will help evaluate agents before deployment, track their actions, and monitor behavior, integrating as telemetry into CrowdStrike's broader detection platform. Falcon Guardian, CrowdStrike's existing detection and response control for AI agents, will absorb Dreadnode's automated security testing capabilities to surface security policy recommendations.

CrowdStrike Acquires Fiddler AI and Dreadnode to Build Out AI Agent Security Platform
ler a análise desta fonte ocultar
CrowdStrike announced agreements to acquire Fiddler AI and Dreadnode, two AI security companies, in deals revealed at its Fal.Con Europe conference in Barcelona. Terms were not disclosed by CrowdStrike, though the Wall Street Journal reported pricing of roughly $400 million for Fiddler and $95 million for Dreadnode. The acquisitions target an emerging gap in AI agent security: agents can hold valid credentials and approved tools yet still make poor decisions, hallucinate completed work, or ignore instructions, a problem traditional code-focused security testing does not address. Fiddler, which will become Falcon Observe, provides post- and pre-deployment observability, tracing agent decisions, flagging drifting or fabricated behavior, and generating audit records, with support for frameworks like LangGraph, Amazon Bedrock, and Google ADK. Dreadnode provides pre-deployment adversarial testing, running over 100 known attack techniques including jailbreaks and prompt injection against models and agents, mapped to standards such as the OWASP Top 10 for LLMs and the NIST AI Risk Management Framework.
Technical Details
Alongside the acquisitions, CrowdStrike introduced new Falcon Guardian runtime protections for AI agents and an AI Kill Switch feature, described by CEO George Kurtz as a control existing outside the model at runtime that allows humans to halt any AI agent regardless of the agent's own behavior or attempts to resist. Kurtz framed this as a shift from traditional security (keeping adversaries out) to a broader AI safety mission (allowing agents to operate at speed under human control).
Remediation
Both Fiddler and Dreadnode products are expected to become generally available within CrowdStrike's fourth fiscal quarter of 2027, with the acquisitions expected to close in the same period pending standard regulatory approvals. Payment will be made mostly in cash, with a stock component vesting over time based on performance conditions.

CrowdStrike has not disclosed official financial terms but is reportedly paying roughly $400 million for Fiddler and about $95 million for Dreadnode, paid mostly in cash with a stock component subject to vesting. The deals are expected to close in Q4 of CrowdStrike's fiscal year 2027 (ending January 31, 2027). Fiddler's technology will be sold as Falcon Observe, monitoring AI agents, tracing reasoning and tool calls, and detecting behavioral drift and hallucinations, while Dreadnode's offensive AI testing platform will feed findings into Falcon Guardian. CrowdStrike also introduced an AI Kill Switch within Falcon Guardian to halt misbehaving AI agents.
Technical Details
Fiddler, founded in 2018 and based in Palo Alto, adds pre-deployment evaluation of AI agents, compliance audit logging, and token usage/spend tracking. Dreadnode, founded in 2023, runs over 100 known AI attack strategies—including jailbreaks, prompt injection, and multi-turn/agent-specific attacks—against AI models, agent reasoning loops, applications, and MCP servers, mapping findings to OWASP Top 10 for LLMs, MITRE ATLAS, and NIST AI RMF frameworks. The Dreadnode team, led by CEO Brad Palm, will join CrowdStrike's Cyber Superintelligence Lab, with testing capabilities expected generally available in Q4 fiscal 2027. This follows a string of recent CrowdStrike acquisitions, including identity security firm SGNL ($740 million) and browser security company Seraphic ($420 million) in January, and AI security firm Pangea in September 2025.
