CrowdStrike unveils Falcon Guardian to secure AI agents at runtime

AI agents are no longer a science experiment. They write code, query databases, execute commands, and interact with cloud services on behalf of users, often without a human in the loop. CrowdStrike’s answer, announced September 1 at its annual Fal.Con conference in Las Vegas, is Falcon Guardian, a dedicated runtime security layer built specifically to protect AI agents at the endpoint level. What Falcon Guardian actually does At a technical level, the product extends CrowdStrike’s existing kernel-level Falcon sensor to create a control point specifically for AI agent activity on endpoints. It provides real-time inventory of AI agents running across an environment, behavioral monitoring to flag unusual actions, and a risk assessment layer that can identify threats such as prompt injection, jailbreaks, and unauthorized data access before they escalate. Prompt injection is roughly the AI equivalent of a SQL injection attack. A malicious instruction is embedded into content that an AI agent is processing, causing the agent to execute unintended commands. As agents gain more privileges within enterprise systems, these attacks become significantly more consequential than a chatbot return...
