SAST hits hard when the scans are slow, the results are noisy, and your release pipeline grinds to a halt. Security teams and developers feel it every time a Static Application Security Testing tool bloats the backlog with false positives or takes hours to run. The promise of catching vulnerabilities early turns into a drag on velocity.
The core problem is latency and clarity. Many SAST solutions run as monoliths. They chew through an entire codebase before surfacing anything useful. That means you wait, often too long, before you know whether the code you just wrote has a critical flaw. Worse, triage becomes a second full-time job. Sorting real issues from the junk slows down delivery, and deadlines slip.
SAST becomes acute in CI/CD workflows. Every delay stacks. Every false positive erodes trust between engineering and security. Teams start bypassing scans or postponing them, which leaves gaps in coverage. Those gaps can be dangerous, allowing exploitable code into production. A modern approach must fix speed without compromising accuracy.
