How do we avoid “stop all deploys” during a security incident?

Pre-define containment moves that are **scoped and reversible**: quarantine a namespace/service, revoke a single token, disable auto-sync for one `ArgoCD` app, or block egress for a suspect workload. Pair that with an evidence proof pack so leadership feels safe resuming normal deploy lanes sooner.

What do auditors actually want to see after an incident?

They want a defensible timeline and proof of control operation: who accessed what, what changed, what was contained, and how you prevented recurrence. An automated proof pack (audit logs + IAM state + deployment diffs + artifact hashes) answers most of that without weeks of manual effort.

We handle regulated data. Can we still move fast?

Yes—segment the regulated **data plane** from the fast-moving **control plane**, enforce private connectivity and least privilege, and put guardrails in CI/CD. The goal is to keep most changes out of the regulated blast radius while still maintaining strong auditability when you do touch it.

Where does policy-as-code fit in incident response?

Policy-as-code prevents repeat incidents and makes response actions safer. Use `OPA`/`Conftest` for Terraform/Kubernetes checks (e.g., no public buckets, no wildcard IAM), and treat the policies like production code: reviews, tests, versioning, and metrics.
