Our organization is moving toward a "Shift Left" security approach, but we are struggling to integrate security scanning without breaking the speed of our DevOps pipeline. We want to incorporate SAST and DAST tools directly into our GitLab CI, but the false positives are overwhelming our developers. How are you handling automated vulnerability management while maintaining a fast release cycle in 2025?

Implementing DevSecOps effectively requires a tiered scanning strategy. You shouldn't run a full DAST scan on every single commit; instead, trigger lightweight SAST during the "Pre-commit" or "Build" phase to catch low-hanging fruit. Save the heavy-duty security audits for the staging environment or weekly scheduled jobs. To handle false positives, use an orchestration layer like DefectDojo to aggregate findings and suppress known non-issues. This keeps the developer's feedback loop tight and prevents "security fatigue" which often leads to teams bypassing critical checks.
Are you currently using "Policy as Code" tools like OPA (Open Policy Agent) to enforce compliance at the infrastructure level before the code even reaches the security scanning phase?
The key is to focus on the "Top 10" vulnerabilities first. Don't try to fix everything at once. Start by blocking builds only on "Critical" and "High" alerts to build trust with the dev team.
Barbara's advice is spot on. We followed this incremental approach and it significantly reduced the friction between our security and engineering departments while improving our overall posture.
James, we haven't looked into OPA yet. Does it work well with Terraform, and can it actually block a deployment if a developer accidentally opens a public S3 bucket? We need something that acts as a hard gate for critical misconfigurations without requiring a manual review for every single infrastructure change.
