Скачать или смотреть We Skipped Static Scanning — A Vulnerability Went Live

I’m Elif, a DevOps engineer at a large UK-based tech company, and this Fix The Buggy Habits story is a reminder of why security scanning must be built into every pipeline from day one. While setting up a new CI/CD pipeline, I skipped adding a Static Application Security Testing (SAST) stage, thinking I’d add it later. The builds passed, peer reviews looked good, and everything seemed fine — until it wasn’t.

A month later, our monitoring tools flagged suspicious activity in production. After a deeper security review, we discovered an input validation flaw in a third-party library that had slipped into production completely undetected. If SAST had been running in the pipeline, it would have flagged the vulnerability in seconds. Instead, we were left exposed until it was manually caught.

The lesson here is clear: don’t treat static scanning as optional. Tools like SonarQube, Checkmarx, or Snyk Code should be part of every CI/CD workflow, regardless of team size. Security is everyone’s responsibility, and baking in DevSecOps practices early is the only way to avoid blind spots that can lead to real-world vulnerabilities.
