AI agents now execute real-time code, creating a critical security paradox. How do we enable autonomy without risking breakouts? This session explores "Hardened Runtimes" using Docker Sandboxes, gVisor, and Kata Containers on K8s. We’ll analyze the "Agent-in-the-Box" pattern to decouple reasoning from execution. Learn to orchestrate secure agents in AKS via RuntimeClasses and see a live demo of a sandbox blocking malicious AI-generated code. Security for the age of autonomous minds.
