Platform Security Policy Framework
A policy-as-code framework that standardizes guardrails across Kubernetes and GCP while making exceptions auditable and time-bound.
Problem
Cloud and Kubernetes platforms need consistent security guardrails, but ad hoc enforcement creates exceptions, bypasses, and unclear ownership.
What I built
I built a platform policy framework for Kubernetes and GCP resources using OPA Gatekeeper and Terraform Sentinel. The framework standardizes controls while creating a trackable exception process for legitimate deviations.
Key design choices
- Codify policies as source-controlled changes.
- Use PR workflows for review and rollout.
- Make exceptions explicit, time-bound, and auditable.
- Expose failures and trends through observability so teams can act without waiting on manual analysis.
Impact
Shifted security enforcement left without blocking engineering velocity. Teams gained clear, self-service guardrails with auditable exception paths, reducing repetitive policy-related support conversations. The framework standardized controls across Kubernetes and GCP resources, making compliance posture visible and measurable rather than ad hoc.
