The single biggest mistake teams make with CI/CD-integrated security tooling is treating it as a one-time setup rather than an ongoing programme.
The scanner is not the security programme. The scanner is a signal generator. The security programme is the process by which signals become fixes, fixes become patterns, and patterns become rules that prevent the same issue from appearing again.
Configurable thresholds give you the controls to introduce that programme without breaking your team's deployment workflow. Use them gradually, communicate the reasoning at each phase, and invest as much in the suppression review process as you do in the initial setup.
A scanner your team trusts and engages with is worth ten scanners that get bypassed.

Next up: the one everyone's been asking about — false positives in SAST, how I built suppression into the scanner, and why managing false positives is as important as finding real vulnerabilities.
