How to use it professionally

Before testing

Confirm authorization, scope, exclusions, test windows, data handling, emergency contacts, and stop conditions.

During testing

Record the asset, request, expected control, observed result, evidence, and any cleanup action. Avoid destructive proof when a safer validation demonstrates the same issue.

After testing

Deduplicate related symptoms, identify the root cause, assign risk in business context, provide actionable remediation, and retest the final implementation.
