Most Kubernetes clusters are one “kubectl apply” away from disaster. This talk shows how to harden your platform so the “wrong” thing is impossible — even for vibe-coded apps. We’ll cover Pod Security Admission, Kyverno/OPA policies, seccomp/AppArmor, default deny egress, and namespace isolation. You’ll leave with a GitOps-ready baseline that protects multi-tenant teams without killing velocity.

Learning outcomes:
- Apply baseline Kubernetes hardening that blocks common misconfigs by default.
- Use policy-as-code to enforce security without manual reviews.
- Roll out guardrails safely in live clusters.
