How to Build a DevSecOps Pipeline from Scratch [2026 Guide]

DevSecOps Pipeline: Build One from Scratch
A DevSecOps pipeline integrates security into every stage of CI/CD — not bolted on at the end. Here is the architecture I use in production.
The 7 Stages
-
Code — pre-commit hooks, secret scanning (TruffleHog, GitLeaks)
-
Build — dependency scanning (Snyk, OWASP Dependency-Check)
-
Test — SAST (SonarQube, Semgrep), unit tests
-
Container — image scanning (Trivy, Grype), base image policies
-
Deploy — IaC scanning (Checkov, tfsec), policy-as-code (OPA)
-
Runtime — DAST (ZAP), runtime protection (Falco)
-
Monitor — SIEM integration, alerting, incident response
Tool Stack
GitHub Actions + Trivy + SonarQube + OPA + Falco + Datadog. Total cost for small team: $0-$200/month using open-source tools.
FAQ
DevSecOps vs DevOps?
Same pipeline, security embedded at every stage instead of added at the end.
