CI/CD Security Pipeline Automation
Architecture
The pipeline was designed to be modular and non-intrusive for developers.
The Stack
- Container Scanning: Trivy for its speed and accuracy.
- SCA: OWASP Dependency-Check for deep analysis of libraries.
- Secrets Scanning: Gitleaks to prevent credential leaks.
Integration Logic
We used GitHub Actions reusable workflows to standardize the check across 50+ repositories.

Business Impact
By shifting security to the left, we reduced the cost of fixing vulnerabilities by an estimated 10x compared to finding them in production during quarterly pentests.
The Context
Engineering teams were shipping container images and third-party dependencies without any automated security gates, creating supply-chain risk.
The Approach
Designed a multi-stage security pipeline integrating Trivy for container image scanning, OWASP Dependency-Check for SCA, and Gitleaks for secrets detection. Built a centralized SARIF reporting layer feeding into GitHub Security tab.
The Impact
Achieved 100% coverage of container registries. Automated detection of 200+ vulnerable dependencies in Q1, with remediation SLAs enforced programmatically via PR labels and Jira integration.
