Understand this story
On November 3, 2026, CrowdStrike announced at Fal.Con EU 2026 its intent to acquire AI security startups Fiddler and Dreadnode. According to SiliconANGLE, The Wall Street Journal reported the deal value at approximately $495 million, with Fiddler accounting for about four-fifths of that. Fiddler provides a risk-testing platform for agents before deployment and uses its custom model Centor to block malicious prompts and harmful outputs in production environments; its technology will be integrated into Falcon Observe to evaluate and explain AI agent behavior. Dreadnode, meanwhile, adds automated AI security testing to the Falcon platform, covering more than 50 attack techniques including jailbreaks, prompt injection, and multi-turn attacks. CrowdStrike plans to make Falcon Observe and Dreadnode generally available in the fourth quarter of fiscal year 2027. The transactions are currently still proposed acquisitions.

CrowdStrike Launches AI Kill Switch on Falcon Guardian Platform
CrowdStrike announced the launch of an AI kill switch in the Falcon Guardian platform, which allows security personnel to terminate the operation of enterprise AI agents in real time, prevent them from restarting, and cut off their access to the corporate network when they deviate from expectations, behave maliciously, or go out of control. The feature is similar to a circuit breaker; after agent activity is detected, a human still decides whether to cut off and restore access. CrowdStrike also announced plans to acquire AI observability startup Fiddler AI and AI security testing company Dreadnode.

CrowdStrike launches AI kill switch on the Falcon Guardian platform
CrowdStrike has launched an AI kill switch in the Falcon Guardian platform, which allows security personnel to terminate the operation of enterprise AI agents in real time, prevent them from restarting, and cut off their access to the corporate network when they deviate from expectations, exhibit malicious behavior, or act out of control. The process can detect internal agent activity, but a human decision is required on whether to cut off and restore access permissions; CrowdStrike Chief Business Officer Daniel Bernard likened it to a circuit breaker. CrowdStrike also announced plans to acquire AI observability startup Fiddler AI and AI security testing company Dreadnode.

CrowdStrike plans to acquire Fiddler AI and Dreadnode for about $495 million
CrowdStrike announced plans to acquire two startups focused on AI agent security, Fiddler AI and Dreadnode; The Wall Street Journal reported the deal value at $495 million, with Fiddler accounting for about four-fifths. Fiddler provides a pre-launch risk testing platform for agents and uses a custom model called Centor to block malicious prompts and harmful outputs in production environments, reportedly adding less than 80 milliseconds of latency; Dreadnode discovers vulnerabilities by simulating cyberattacks, covering more than 100 intrusion techniques, and checks the risks of the MCP servers used by agents. CrowdStrike is also adding an AI Kill Switch feature to Falcon Guardian, which can manually shut down misbehaving agents, cut off their network access, and prevent them from restarting.

CrowdStrike Plans to Acquire Fiddler and Dreadnode, Expanding Its AI Security Product Line
On November 3, 2026, CrowdStrike announced plans to acquire Fiddler and Dreadnode, with both deals unveiled at Fal.Con EU 2026. Fiddler's technology will become Falcon Observe, used to evaluate and explain the behavior of AI agents; Dreadnode, meanwhile, will add automated AI security testing to the Falcon platform, covering more than 50 attack techniques including jailbreaks, prompt injection, and multi-turn attacks, and aligning with the OWASP Top 10 for LLMs, MITRE ATLAS, and the NIST AI Risk Management Framework. CrowdStrike plans to make Falcon Observe and Dreadnode generally available in the fourth quarter of fiscal year 2027, and Dreadnode's test results will also feed into Falcon Guardian as policy recommendations.
