SECURE CI/CD WITHOUT DRAG

SCAN IN PARALLEL
SAST, container scans, and secret detection should run concurrently, not in sequence. Cache dependency layers between builds. Most pipeline slowdowns come from poor caching, not from the scanners themselves.
Set time budgets per stage. If Trivy exceeds three minutes, fix the image size before disabling the scan.
SEVERITY GATES
Block merges on critical findings only. Warnings become tickets with SLA tags. Developers ignore pipelines that fail on informational noise. Tune rules to your stack so findings are actionable.
Semgrep custom rules beat generic OWASP packs for teams with known frameworks. Write rules when you fix a bug so it does not return.
FEEDBACK IN THE PR
Post scan results as PR comments with file and line references. A developer should fix the issue without opening a separate dashboard. Gitleaks findings include the commit that introduced the secret.
Security tooling that lives outside the developer workflow gets disabled. Meet people where they already work.
SUPPLY CHAIN AS DEFAULT
Pin base images and verify signatures where possible. Scan lockfiles, not just Dockerfiles. A vulnerable dependency in production is a pipeline miss, not a runtime surprise.
DevSecOps is not a phase. It is the pipeline your team runs every day.
