Purpose
CI Enforcement applies policy decisions inside the pull request path. Its job is to translate security thresholds into a pass-or-fail outcome that is visible inside GitHub and CI, so teams can block unsafe changes consistently rather than relying on manual review cycles.
Recommended Rollout
- Begin in report-only mode.
- Review finding volume, ownership, and false positives.
- Enable blocking for critical issues first.
- Expand to high-severity issues where confidence is strong.
- Standardize org-wide policies and exception handling.
Core Controls
- Repository and org-wide severity thresholds
- Required checks before merge
- Documented exemptions with expiration
- Recorded policy decisions with timestamps and actors
Operating Model
Source Control
Status checks surface directly in the developer workflow.
Policy Layer
Thresholds and exemptions determine when a finding becomes merge-blocking.
Evidence Layer
Every pass, fail, and override produces an auditable decision trail.
Implementation Guidance
- Do not start with maximum strictness. Blocking too early usually creates exemption sprawl and weakens long-term credibility.
- Make exceptions explicit. Exception paths should require owner, reason, and expiry so temporary risk does not become permanent policy bypass.
- Keep policy and remediation connected. Blocking is effective only when teams can understand what failed and how to resolve it.
- Use org-wide defaults sparingly. Mature programs often keep a common baseline and then tune for especially sensitive repositories.
Outputs
- Pass or fail status in CI and pull requests
- Policy rationale tied to the triggered finding
- Exception and override records
- Audit evidence for review and compliance activity
Best Fit
CI Enforcement is best suited for teams that need merge controls to be predictable, visible, and measurable across many repositories and many contributors.
