Policy as Code

ELI5 — The Vibe Check

Policy as Code means writing your rules and compliance requirements as actual code that gets enforced automatically. Instead of a wiki page saying 'all S3 buckets must be encrypted,' you write a policy that blocks unencrypted buckets from being created. The rules enforce themselves. No more 'oops, forgot to check' moments.

Real Talk

Policy as Code (PaC) is the practice of defining organizational policies — security, compliance, operational standards — as version-controlled, testable code. Tools include Open Policy Agent (OPA), HashiCorp Sentinel, AWS Config Rules, and Checkov. Policies are evaluated during CI/CD, infrastructure provisioning, or at runtime to enforce guardrails automatically.
