Workflow
From target input to a release-ready report
01
Configure the scope
Provide URLs or upload a ZIP archive, then choose the scanners needed for that release.
Boundary validation prevents invalid scan states before execution.
02
Run isolated scanners
Every scanner runs in rootless containers while progress streams live over SSE.
Container isolation keeps scanner behavior reproducible and debuggable.
03
Ship with one report
Review merged findings with severity, evidence, and WCAG mapping in a single view.
Unified output removes context switching across scanner tools.
