NYDFS Part 500

A Part 500 cybersecurity audit from people who know mortgage banking.

New York requires larger licensees to get independent audits of their cybersecurity program, and most covered companies must file an annual certification of compliance or an acknowledgment of noncompliance. Garrett, McAuley & Co. leads the audit, works with an information security firm whose auditors hold the ISACA CISA certification, and writes a report your board can act on.

What the audit covers

  • Board oversight: the written program, board approval, and the CISO's authority and annual report
  • Risk assessment, and whether it actually drives the program
  • Vendor management for key vendors such as the loan origination system, subservicer, and cloud providers
  • Access controls, multi-factor authentication, and asset inventory
  • Monitoring, encryption, vulnerability management, and penetration test follow-up
  • Incident response, business continuity, and the DFS notice and certification deadlines
  • Related Fannie Mae, Freddie Mac, and FTC Safeguards Rule requirements

What the rules require

  • Class A companies must design and conduct independent audits of their cybersecurity program. How often depends on their risk assessment.

    23 NYCRR 500.2(c) (opens in a new tab)

  • Every covered company that is not fully exempt must file an annual certification of material compliance, or an acknowledgment of noncompliance, by April 15.

    23 NYCRR 500.17(b) (opens in a new tab)

  • Class A status depends on gross revenue and employee count over the last two fiscal years. Only affiliates that share information systems, cybersecurity resources, or part of the cybersecurity program count.

Common questions

Does Part 500 apply to mortgage bankers and servicers?
Yes, if you hold a New York mortgage banker license or mortgage loan servicer registration under the Banking Law. Smaller companies may qualify for limited exemptions under section 500.19.
Who needs an independent Part 500 audit?
Class A companies must have independent audits, on a schedule their risk assessment supports. A Class A company has at least $20 million in gross annual revenue in each of the last two fiscal years. That total counts all of its own business plus the New York business of its affiliates. It also has more than 2,000 employees, averaged over the last two fiscal years, or more than $1 billion in gross annual revenue in each of those years. Only affiliates that share information systems, cybersecurity resources, or part of the cybersecurity program count toward these totals.
We are not Class A. Is an audit still useful?
Yes. Most covered companies must file a certification of compliance, or an acknowledgment of noncompliance, each April 15. An independent audit gives the CEO and CISO a documented basis for that filing.
Does the audit include penetration testing?
The audit reviews your most recent penetration test and vulnerability scans, and whether your team fixed the findings on time. If you need a new test, we can recommend specialist firms.
How long does the audit take?
Most audits take several weeks from kickoff to final report, depending on your size and how current your documentation is.
Do you need access to our systems?
No. Your team shows us the evidence through reports, screenshots, and screen-share walkthroughs. We also check what anyone can see from the internet, such as your public websites and email security settings.
