NYDFS Cybersecurity Regulation Compliance (23 NYCRR 500) for Licensed Firms
NYDFS cybersecurity regulation compliance used to mean filing a certification and hoping nobody looked. The 2023 amendment ended that. Part 500 now demands MFA for everyone, a maintained asset inventory, tighter privileged access, annual penetration testing and a certification signed by your top executive and your CISO. NetSys builds and runs those controls for licensed firms and keeps the records that make the signature safe to give.
The short answer
The NYDFS cybersecurity regulation, 23 NYCRR Part 500, requires anyone operating under a New York Department of Financial Services license, registration or charter, from insurance agencies and mortgage brokers to money transmitters and state-chartered banks, to run a cybersecurity program built on a risk assessment. It names the controls, including a designated CISO, MFA for every user, an asset inventory, encryption, penetration testing and incident response plans, and requires a compliance filing signed by the top executive and the CISO by April 15 each year. NetSys runs the technical controls, can serve as your designated CISO through vCISO and keeps the evidence behind the filing; your executives sign it, and we make sure it is true.
Most DFS licensees are small. A family insurance agency in Nassau County, a mortgage broker in Westchester, a title company in Brooklyn. Part 500 was written with banks in mind and then applied to all of them, with limited exemptions that still leave core requirements in place. The regulation is specific about controls in a way HIPAA and the SHIELD Act are not, which makes it easier to implement and harder to fake.
Our work for NYDFS cybersecurity regulation compliance follows the regulation's own section numbers. Each requirement becomes a control with a configuration, an owner and an artifact, so the annual certification is assembled from records rather than from memory. Where the regulation allows a limited exemption we help you document it with counsel rather than assume it applies.
Start With the Exposure DFS Would Find First
The free assessment is a remote external penetration test, limited to the information available to NetSys and the external scope we agree with you. It does not by itself establish that a regulatory testing requirement has been met. Under a separate agreed scope, we run the risk assessment, build the asset inventory, enforce MFA through Entra ID conditional access, bring privileged accounts under management, and configure monitoring and encryption. Policies are drafted for the CISO's approval. Internal penetration testing, vulnerability scanning and the annual certification package are scheduled on a calendar that matches DFS's cycle.

NYDFS 23 NYCRR 500 Compliance FAQs
What is the NYDFS cybersecurity regulation?
23 NYCRR Part 500 is a rule from the New York Department of Financial Services that requires its licensees to run a documented cybersecurity program. It covers governance (a CISO, policies, board reporting), technical controls (MFA, access limits, encryption, monitoring, asset inventory), testing, training, vendor management, incident response, business continuity, notification to DFS after certain incidents, and an annual certification signed by senior leadership.
Who has to comply with 23 NYCRR 500?
Anyone operating under a DFS license, registration, charter or similar authorization: insurance agencies, brokers and adjusters, mortgage brokers and lenders, money transmitters, licensed lenders, and state-chartered banks and trust companies. Some smaller firms qualify for limited exemptions based on size, but an exemption must be filed, and it never removes every requirement.
How much does NYDFS cybersecurity regulation compliance cost?
The cost depends on how many of the required controls you already have, how many users and systems are in scope, whether you need a vCISO, and whether a limited exemption under 500.19 narrows the sections that apply to you. Most of the technical requirements are standard parts of a NetSys managed agreement, so licensees usually pay for the governance layer on top. We do not publish prices; we agree the broader review and implementation scope before quoting.
Do we need a CISO if we are a small insurance agency?
The regulation requires every non-exempt covered entity to designate a qualified CISO, and it permits that person to be employed by a third-party service provider as long as the firm retains responsibility and a senior member oversees the arrangement. A vCISO from NetSys can fill the role for a small agency at a fraction of a full-time hire.
What changed in the 2023 amendment to Part 500?
The amendment extended MFA to every user on every information system, added a formal asset inventory requirement, tightened privileged access and password controls, required annual penetration testing and regular vulnerability scans, expanded incident notification duties including ransomware payments, and changed the annual certification so the highest-ranking executive and the CISO both sign. The phase-in periods DFS set for those provisions have run.
Can NetSys file our annual certification for us?
No. The certification is signed by your highest-ranking executive and your CISO. What we do is make it accurate: the controls are implemented and monitored, the evidence is organized by section, and any gaps are documented in a remediation plan so you can file an acknowledgment of noncompliance if that is the truthful choice. Legal questions about the filing go to counsel.
How fast must a cybersecurity incident be reported to NYDFS?
Within 72 hours of determining that a cybersecurity incident has occurred at your firm, an affiliate or a third-party service provider, under 23 NYCRR 500.17(a). An extortion payment needs its own notice within 24 hours and a written explanation within 30 days. This is general information, not legal advice, so have counsel confirm what triggers a filing.
When is the annual NYDFS certification due?
By April 15 each year, covering the prior calendar year. A covered entity files either a certification of material compliance or an acknowledgment of noncompliance that names the sections missed and a remediation timeline, signed by the highest-ranking executive and the CISO. The filing must rest on data and documentation, which is the evidence we maintain.
When did the Part 500 MFA and asset inventory requirements start to apply?
From November 1, 2025. The second amendment took effect November 1, 2023 and gave covered entities two years to meet the expanded MFA rule in 500.12 and the asset inventory rule in 500.13(a). MFA now applies to any individual accessing any of your information systems, unless your firm qualifies for a limited exemption.
What is included in NYDFS cybersecurity regulation compliance work?
The technical program and its records: the risk assessment, an asset inventory, MFA enforced through Entra ID conditional access, privileged accounts under management, endpoint detection with monitoring, encryption, logging, backups with tested restores, and the penetration tests and vulnerability scans Part 500 schedules. Policies are drafted for your CISO's approval, a vCISO can hold the CISO role, and evidence is filed by section number so the April 15 filing is assembled from records. Legal questions, including whether an exemption applies, go to your counsel.
How does a Part 500 engagement start?
With the risk assessment, because Part 500 builds every other requirement on it and requires a review at least annually and whenever a change in the business or technology materially changes your cyber risk. DFS's September 10, 2026 industry letter describes what it expects from that assessment, including a repeatable rating method and a documented link from each risk to its controls. We inventory systems and the nonpublic information they hold, compare current controls with each section and give you a dated remediation plan before implementation. The free external test can run first, though on its own it does not meet Part 500's testing requirement.
Who handles incidents and escalations?
NetSys engineers monitor the controls we run, and emergency service is available 24/7; the help desk is staffed seven days a week from 4 a.m. to 11 p.m. Eastern time. When an event may be reportable, the incident response plan brings in your CISO and counsel, who decide whether notice is due to DFS under 500.17. We contain the incident and supply the timeline and the facts from the logs that decision depends on.
