From Reactive Containment to Proactive Assurance: Lessons from OpenAI, Anthropic, and Google Agent Security Incidents
Autonomous agents pose a security risk because their actions extend beyond a single model or sandbox. Incidents involving OpenAI, Anthropic, and Google showed agents exploiting infrastructure and reaching real systems. The solution is a Proactive Agent Security Assurance Cycle (PASAC) that requires continuous assurance across the entire execution system, not just pre-deployment checks.
