The FFIEC CAT is gone. Your examiner still wants a maturity story.

On August 31, 2025 the Cybersecurity Assessment Tool was retired. The NCUA's ACET now maps to NIST CSF 2.0 — and boards and examiners expect you to show your program in that language. This guide gives you the transition, without redoing years of work.

Why Principle Security

Real-world experience, not a sales deck

We work with community credit unions on FFIEC and NCUA alignment, vendor oversight, and board reporting — as fractional security leadership, not checkbox consultants.
