The build failed. The alert came seconds after the commit hit the pipeline. You check the logs and see it: the feedback loop was too slow to catch the defect earlier. That delay cost hours instead of minutes.
Feedback Loop IAST is the answer to that gap. Interactive Application Security Testing that runs inside the app itself shortens feedback cycles. It watches real execution, not just static files. It flags vulnerabilities the moment code paths open them. No waiting for the next scheduled scan. No blind spots between deploys.
A tight feedback loop turns security from a separate phase into a constant process. IAST makes this possible by integrating directly into live systems. Each request, each test run, feeds instant results back to developers. This eradicates the lag between writing risky code and knowing about it. Instead of hunting through static reports later, errors surface inside your workflow.
