Cybersecurity for Financial Services Firms Under NYDFS, SEC and FTC Rules
Cybersecurity for financial services firms is mostly the same work under different rulebooks. A New York insurance agency answers to DFS, an SEC-registered adviser to the SEC, and a tax practice to the FTC. Some firms answer to two: a New York mortgage broker is both a DFS licensee and a financial institution under the FTC Safeguards Rule. We build the controls once and tag each to every section that requires it.
The short answer
Cybersecurity for financial services firms starts with the rule that applies: NYDFS 23 NYCRR 500 for New York DFS licensees, SEC Regulation S-P for registered advisers and broker-dealers, and the FTC Safeguards Rule for most other non-bank firms under GLBA. NetSys builds one control set, tags it to each rule you face, and keeps the evidence your examiners ask for.

This page is for CPA and tax firms, hedge funds and other investment advisers, insurance agencies, and mortgage brokers and lenders. Firms like these often have a small team, no security staff and a compliance officer with other duties, yet a regulator expects them to protect customer data and prove it.
The rules differ more in structure than in substance. Part 500 is specific: a CISO, MFA for every user, an asset inventory, notice to DFS within 72 hours of determining an incident occurred, and a filing each April 15. Regulation S-P centers on an incident response program and notice to affected customers within 30 days. The Safeguards Rule requires a Qualified Individual, MFA, testing and notice to the FTC within 30 days for events involving 500 or more consumers. New York's SHIELD Act treats a firm that complies with GLBA rules or Part 500 as meeting its safeguard requirement.
Build once, tag to each rule
Most of what these rules require is the same control described in different words. MFA appears in Part 500 at section 500.12 and in the Safeguards Rule at 16 CFR 314.4(c)(5); incident response planning appears in Part 500, Regulation S-P and the Safeguards Rule. So we implement each control once, on your real systems, and record which sections it satisfies. When DFS, the SEC, the FTC or a cyber insurer asks a question, the answer is the same evidence, filed under their section number. Where the rules differ, we build to the stricter control and track each notice deadline separately.

- Service provider contracts checked for breach notice within 72 hours, as Regulation S-P expects

Which rule applies, and what NetSys covers
Find your firm type, then see what we provide and what stays with you.
| Rule | Who it covers | NetSys provides | Not included |
|---|---|---|---|
| NYDFS 23 NYCRR 500 | New York DFS licensees, such as insurance agencies, mortgage brokers, licensed lenders and money transmitters | Required controls, the asset inventory, the 72-hour incident process and evidence for the April 15 filing | Signing the filing, which your highest-ranking executive and CISO do |
| SEC Regulation S-P | SEC-registered investment advisers, broker-dealers, investment companies and transfer agents | Incident response program mechanics, service provider oversight and required records | Customer notification decisions, which stay with your CCO and counsel |
| FTC Safeguards Rule (16 CFR Part 314) | Non-bank firms under GLBA, such as tax preparers, finance companies, mortgage brokers and advisers not required to register with the SEC | Required controls, testing, Qualified Individual support and the facts for any FTC notice | A legal opinion on coverage or exemptions |
| NY SHIELD Act (GBL §899-aa and §899-bb) | Any business holding New York residents' private information | Safeguards documented through your GLBA or Part 500 program | Breach notification decisions |
Many firms fall under more than one rule. NetSys is not a certifying body or a law firm, and nothing here is a compliance certification. This is general information, not legal advice.
How onboarding runs
The rule set comes first, then the controls that close the widest gaps.
- Scoping call with your principal and compliance officer: licenses, registrations, headcount and systems
- Rules and exemptions confirmed in writing, with counsel where needed
- An inventory of customer information across systems, portals and service providers
- First controls: missing MFA, unmanaged admin accounts, unencrypted devices and untested backups
- Incident runbook and vendor oversight process drafted with your CCO
- Evidence library opened section by section, ready for the next filing or exam
How pricing works
The technical controls run inside the NetSys managed agreement, priced per user per month. We do not publish prices. What moves the price:
- Users, devices and offices
- How many rules apply, and whether a limited exemption narrows them
- Number of service providers to oversee
- vCISO time, if we hold a CISO or Qualified Individual role
- Separately scoped testing, such as penetration tests
Firms that keep their current IT provider can bring NetSys in for the security program alongside it.
Cybersecurity for Financial Services FAQs
Which cybersecurity regulations apply to financial firms in New York?
It depends on your license or registration. DFS licensees, such as insurance agencies and mortgage brokers, follow 23 NYCRR 500. SEC-registered advisers and broker-dealers follow Regulation S-P. Most other non-bank firms, including tax preparers, fall under the FTC Safeguards Rule. The SHIELD Act covers anyone holding New Yorkers' private information. This is general information, not legal advice.
What does NYDFS Part 500 require of small firms?
Small firms still need the core controls, since Part 500 grants only a limited exemption below 20 employees and contractors, $7.5 million in revenue in each of the last three years, or $15 million in assets. Those include a risk assessment, MFA for remote and privileged access, an asset inventory, training, 72-hour incident notice and the April 15 filing.
How do RIAs comply with Reg S-P?
An SEC-registered adviser needs a written incident response program for unauthorized access to customer information, notice to affected individuals within 30 days, oversight of service providers that must report breaches within 72 hours, and records of all of it. The compliance dates passed on December 3, 2025 for larger advisers and June 3, 2026 for smaller ones.
What does cyber security in financial services involve day to day?
Day to day, it is identity and email protection first: MFA, conditional access and alerts on mailbox rules, because reported business email compromise losses passed $3 billion in 2025, according to the FBI's IC3. Then come least-privilege access, encryption, monitored endpoints, logging, immutable backups and scheduled reviews of the vendors that hold your customers' data.
Can NetSys act as our CISO or Qualified Individual?
Yes, through our vCISO service, where the rule allows it. Part 500 lets the CISO be employed by a third-party service provider, and the Safeguards Rule allows the same for the Qualified Individual. In both cases your firm keeps responsibility for compliance and names a senior person to direct and oversee the arrangement.
Does the SHIELD Act add anything if we already follow Part 500 or GLBA?
Not for safeguards, if your program is compliant. GBL §899-bb treats a business that is subject to and compliant with GLBA regulations or Part 500 as a compliant regulated entity. The breach notification duty in GBL §899-aa still applies. We keep the mapping between your program and the SHIELD safeguard categories on file, so the overlap is documented.
Is this a compliance certification?
No. NetSys is not a certifying body. Under Part 500, your highest-ranking executive and CISO sign the April 15 certification, or an acknowledgment of noncompliance if that is the accurate filing. What we provide is the control evidence and a current gap list, so whoever signs knows exactly what the filing rests on.
