IT Support for Financial Services Firms in New York City
A small New York City financial firm can answer to the Department of Financial Services, the SEC or the FTC, and sometimes to two of them at once. We run the firm's systems and keep one set of controls, with the evidence behind it, that meets whichever rules apply. From our Brooklyn office, engineers cover the five boroughs on-site.

Cybersecurity for financial services firms in NYC
Most engagements here start with one question: which rulebook covers the firm? A DFS-licensed insurance broker or lender files its compliance certification or acknowledgment with DFS by April 15 each year. An SEC-registered adviser needs a written incident response program and 30-day customer notice under Regulation S-P. A state-registered adviser falls under the FTC Safeguards Rule, and a New York mortgage broker, registered with DFS, is also a financial institution in the FTC's eyes. We build one control set to the strictest rule that applies and keep the evidence current. Our financial services page covers the practice in general, and hedge funds and family offices have their own page; this one covers New York City's regulators and our on-site coverage in the five boroughs.
Everything else about how we serve the area, including coverage, on-site cadence and the honest answer about where our office is, lives on our New York City location page.
Which rules apply to NYC financial firms
NYDFS 23 NYCRR 500
Covers any firm that holds, or needs, a license, registration or charter under New York's Banking, Insurance or Financial Services Law. Since November 1, 2025, multifactor authentication is required for anyone signing in to a covered firm's systems, and a documented asset inventory must be kept. Cybersecurity incidents go to DFS within 72 hours, and the annual compliance filing is due April 15.
SEC Regulation S-P (amended 2024)
Covers SEC-registered advisers, broker-dealers, investment companies, funding portals and transfer agents. The amended rule asks for an incident response program in writing, a 30-day deadline for telling customers their sensitive information was reached without authorization, and contracts that make service providers report a breach inside 72 hours. Larger firms have complied since December 3, 2025, smaller ones since June 3, 2026.
FTC Safeguards Rule (16 CFR Part 314)
Covers non-bank financial institutions such as mortgage brokers, finance companies, check cashers and advisers not required to register with the SEC. The rule requires a written information security program under a Qualified Individual, MFA, encryption and vendor oversight, and a report to the FTC within 30 days when unencrypted information on 500 or more consumers is acquired without authorization.
NY SHIELD Act (GBL §899-aa)
A breach of New York residents' private information must be disclosed to them within 30 days of discovery and reported to the Attorney General, the Department of State and the State Police, and to DFS when the firm is a Part 500 covered entity.

Financial Services Firms in New York City: FAQs
Who provides IT support for financial services firms in NYC?
NetSys provides it from our Brooklyn office, with engineers on-site across the five boroughs. We run the help desk, monitoring, Microsoft 365, identity and email security, endpoint detection and backups, and we keep the records an examiner or auditor asks for, current and dated. Client names never appear in our marketing.
What compliance rules apply to financial services firms in NYC?
It depends on the firm's licenses: NYDFS 23 NYCRR 500 for DFS licensees, SEC Regulation S-P for registered advisers and broker-dealers, and the FTC Safeguards Rule (16 CFR Part 314) for most other non-bank firms. New York's SHIELD Act covers breach notice for everyone. This is general information, not legal advice.
How fast is on-site response in NYC?
Remote work begins first, ordered by severity under the response-time table on our managed IT services page, and the on-site window for your office is agreed in writing. Engineers travel from Brooklyn to anywhere in the five boroughs, and planned work, such as a firewall change, is scheduled around your business hours.
What do managed IT services for financial services firms in NYC include?
Day to day: an engineer-led help desk, 24/7 monitoring, patching, Microsoft 365 administration and managed devices. Around that sit the controls the regulators name, including MFA, encryption, access reviews, an asset inventory and immutable backups with restores we run and date. Everything runs month to month, with evidence kept as the work happens.
Does a small DFS-licensed firm still need MFA and an asset inventory?
Yes. The §500.19(a) limited exemption, for firms with fewer than 20 employees and contractors, under $7.5 million in revenue or under $15 million in assets, removes some requirements. DFS still expects MFA for remote access, third-party applications holding nonpublic information and privileged accounts, plus an asset inventory, annual training and the April 15 filing.
