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

By Kehinde Ogunlowo ·

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

  1. Code: pre-commit hooks, secret scanning (TruffleHog, GitLeaks)

  2. Build: dependency scanning (Snyk, OWASP Dependency-Check)

  3. Test: SAST (SonarQube, Semgrep), unit tests

  4. Container: image scanning (Trivy, Grype), base image policies

  5. Deploy: IaC scanning (Checkov, tfsec), policy-as-code (OPA)

  6. Runtime: DAST (ZAP), runtime protection (Falco)

  7. 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.
