Where this comes from

Every module on this site is distilled from real engagements at named banks. No theory, no consultancy slides, no AI-generated filler. The author was the one in the room when the BaFin meeting happened, when the IRBA validation was signed off, when the AML rollout went live. References on request, with the appropriate confidentiality.

How to use it

  • Read it once end-to-end before your next BaFin/audit prep meeting.
  • Share specific sections with your IT, methodology, and compliance leads.
  • If something is unclear or contradicts your situation, ask the Andreas-Bot or write to [email protected].

Disclaimer: this module is professional content based on documented engagements. It is not legal, regulatory or audit advice for your specific institution. Use it as a thinking tool, not a substitute for your own qualified review.
