The amended Part 500 finished phasing in on November 1, 2025 with MFA for every user of every information system and a full asset inventory that records owner, location, classification, support end date and recovery time. What licensees must now have, the reporting clocks, and how each requirement maps to AWS services.

23 NYCRR Part 500 applies to anyone licensed under New York's Banking, Insurance or Financial Services Law, which includes carriers, agencies and many MGAs and producers doing business in the state. The second amendment, adopted in November 2023, phased in over two years. The last requirements took effect on November 1, 2025.

What the final phase added

  • MFA for any individual accessing any of the covered entity's information systems, regardless of location, user type or data. The exception is compensating controls approved in writing by the CISO and reviewed at least annually, or a limited exemption.

  • An asset inventory that tracks, for each information system, its owner, location, classification or sensitivity, support expiration date and recovery time objective.
