Fiddler's agent observability tools are planned for Falcon Observe, adding pre-deployment evaluation, tracing of reasoning and tool calls, production monitoring for behavioral drift and hallucinations, audit logs, and token-spend tracking. Dreadnode's platform uses plain-language test descriptions to run over 100 AI attack strategies against models, agent loops, applications, and MCP servers; it ranks findings, maps them to security frameworks, and sends policy recommendations to Falcon Guardian. The deals are expected to close in fiscal Q4 2027, and Dreadnode testing is expected to become generally available then. Separately, Falcon Guardian's AI Kill Switch lets authorized administrators halt an agent, prevent restart, and cut its network access. ### Source excerpt The acquisitions will add AI agent observability and automated AI security testing capabilities to the CrowdStrike Falcon platform.
