Published on 2026-02-205 min readFlorian

Before the audit: gather information

  • Application URL (production, staging, admin)
  • Technical stack
  • Recent changes
  • Test accounts (optional for external review)
  • Desired scope
  • During external review

    Nothing to do. No access needed, no coordination required.

    After the audit: action plan

  • Read the full report
  • Fix critical flaws first
  • Schedule a re-test
  • Keep the report (GDPR due diligence evidence)
  • Related articles

    Three adjacent analyses to keep exploring the same attack surface.
