    NYDFS Part 500 November 2025 Amendments: What Changed for Third-Party Device Access

    Ensure Team November 18, 2025 8 min read

    What Changed

    The amended 23 NYCRR 500 expanded MFA requirements to all individuals accessing information systems — including brokers on unmanaged devices.

    Key Sections Affected

    • §500.12 Multi-Factor Authentication: Now applies to all individuals, not just employees
    • §500.14 Monitoring: Enhanced requirements for access activity monitoring
    • §500.17 Incident Response: Tighter notification timelines

    What This Means for Carriers

    If your independent agents access any system containing nonpublic information, you now need documented evidence that:

    1. MFA is enforced at every login
    2. The device used meets your security baseline
    3. You can produce audit logs showing compliance

    The Attestation Challenge

    Your annual CISO attestation now requires you to certify compliance across all access points — including the thousands of unmanaged devices used by your independent distribution network.

    This is where most carriers struggle. You can't attest to controls you can't verify.
