Wealth Management IT Support in Nassau County, NY
The advisers who serve Nassau County families work from offices along Jericho Turnpike, Stewart Avenue in Garden City and Northern Boulevard in Great Neck and Manhasset, often in teams small enough that one person handles compliance and IT. NetSys gives RIAs, family offices and broker-dealer branches the controls the amended Regulation S-P expects, manages the devices and vendors behind them, with engineers who drive out from Brooklyn for hands-on work.
The short answer
NetSys provides IT support and managed IT for wealth management firms, registered investment advisers and family offices in Nassau County. We run Microsoft 365 with Entra ID Conditional Access, ThreatDown detection and response, Barracuda email filtering, Keeper, Intune-managed laptops and phones and backups we restore on a schedule, and we document the incident response program and service-provider oversight that amended Regulation S-P requires. Nassau falls within our on-site coverage, so most support is remote and engineers visit for network, hardware and office moves. Terms are month to month.

Advising Nassau families: where the work happens
Nassau is a wealthy county. The Census Bureau's 2020 to 2024 estimate puts its median household income at $146,202, and the North Shore's old Gold Coast villages include some of its most affluent communities. Advisory offices sit in the Jericho Quadrangle and along Jericho Turnpike, along Garden City's Stewart Avenue and Franklin Avenue, at RXR Plaza in Uniondale, along Marcus Avenue in Lake Success and above the shops of Great Neck and Manhasset. Nassau also accounted for nine of the ten largest Long Island office leases signed in the third quarter of 2026, by Cushman & Wakefield's count. Teams are often small and layered: an RIA with a dually registered adviser who answers to a broker-dealer, a partner who holds an insurance license, a family office handling bill pay and tax documents for one household. The systems repeat from firm to firm: custodian platforms, a CRM, portfolio management and reporting, financial planning software, e-signature and secure file exchange, plus Microsoft 365. Each one is a door into client money, so identity and vendor oversight come before everything else.
Support for a Nassau advisory office, at the desk and on site
Advisers notice IT when it fails at 9:25 a.m., so we patch and restart outside market hours and fix most problems remotely. Remotely, we can clear a locked Microsoft 365 account, repair a broken Outlook profile or re-enroll a phone in Intune while the adviser stays at the desk, and the help desk answers calls daily between 4 a.m. and 11 p.m. Eastern, so evening client reviews and weekend planning sessions are covered. Monitoring and emergency service run without a break, and ransomware, a dead circuit or a compromised mailbox reaches your dedicated engineer directly. From Park Slope, Lake Success is about 35 to 40 minutes by car and Jericho about 50, so on-site visits are booked for work that needs hands: a conference room for client meetings, monitors and docks, a firewall or switch, cabling or an office move.
Custodians, CRM and the records an examiner asks for
Examiners and broker-dealer compliance teams want to see the same few things, and most of them are IT records. We keep a written inventory of every system and vendor that holds client data, with who has access, how they sign in and when access was last reviewed. Where custodian platforms, the CRM and reporting tools support single sign-on through Entra ID, staff sign in once with multifactor authentication and lose access everywhere when they leave. Email is archived under a retention policy your compliance officer sets, and business texting runs through an approved, archived channel rather than personal phones. The vendor list feeds the service-provider oversight that Regulation S-P now requires, including the contract terms on breach notice. When an examiner or a client's attorney asks how data is protected, the answer comes from documents rather than memory.
Impersonation, transfer requests and continuity
The most common attack on an advisory firm is not technical. A message arrives from a client's real but compromised email asking to move money to a new account, or a spoofed custodian alert pushes an adviser to a fake login page. We answer with procedure and controls: verbal confirmation through a number already on file for every new payee or change, a second approver, Barracuda's impersonation filters, a DMARC policy on your domain and KnowBe4 exercises built around transfer requests. Continuity is the other half. The remnants of Ida brought a federal disaster declaration that included Nassau in September 2021, and South Shore offices remember Sandy's flooding in 2012. We keep files and mail in Microsoft 365, the firewall on battery with a cellular backup and a tested plan for working from home, and broker-dealer branches add their member firm's own continuity plan under FINRA Rule 4370.

Rules that shape IT for Nassau wealth managers
SEC Regulation S-P, as amended in 2024
The amended rule requires each covered adviser or broker-dealer to run a written incident response program able to detect, contain and recover from unauthorized access to customer information. Clients whose sensitive information was, or is reasonably likely to have been, accessed must hear from the firm within 30 days of it becoming aware, and service providers must be required to report breaches within 72 hours. Compliance was due December 3, 2025 for larger entities and June 3, 2026 for smaller ones.
New York adviser registration
Advisers not registered with the SEC register with the New York Attorney General's office once they have six or more New York clients, and a firm based in New York generally moves to SEC registration at $25 million in assets under management. State-registered advisers pay a $200 annual fee through IARD, file an annual updating amendment and send the office a balance sheet and income statement within 90 days of fiscal year end.
NYDFS Part 500 for insurance-licensed advisers
An adviser who also holds a New York insurance producer license operates under the Insurance Law and can be a covered entity under 23 NYCRR Part 500. Since November 1, 2025, Part 500 has required multifactor authentication for anyone accessing a covered entity's information systems and a documented asset inventory, while small licensees can claim a partial exemption if, with affiliates, they have fewer than 20 people on staff counting contractors, revenue below $7.5 million in each of the last three years, or year-end assets below $15 million. Annual compliance filings are due April 15.
New York SHIELD Act and FINRA continuity
Account numbers paired with access codes, and Social Security numbers, fall within section 899-aa's definition of private information. Section 899-bb treats an adviser that follows the Gramm-Leach-Bliley safeguards, Regulation S-P among them, or Part 500 as already meeting the state's safeguards duty, though the 30-day notice to affected residents still applies. Broker-dealer branches also follow their member firm's continuity plan under FINRA Rule 4370. This is general information, not legal advice.

Wealth Management Firms in Nassau County: FAQs
Who provides IT support for wealth management firms in Nassau County?
NetSys is the outside IT department for RIAs, family offices, financial planners and broker-dealer branches in Nassau County, working from our office in Brooklyn. We run devices, Microsoft 365, identity, email security, backups and the network, keep the vendor inventory and incident response documentation that examiners ask for, and deal with custodian, CRM and portfolio vendors on platform issues. Founded in 1998, NetSys retains 98% of its clients, none of them on long contracts.
Do you provide on-site IT support for financial advisors in Nassau County?
Yes. Our engineers work in person at advisory offices anywhere in Nassau, including Jericho, Garden City, Manhasset, Great Neck, Lake Success and Uniondale. Visits cover conference-room and client-meeting technology, workstations and monitors, firewalls and switches, cabling and office moves, and we schedule them outside market hours where we can. Everyday problems are handled remotely first, which is usually quicker than waiting for a car on the Long Island Expressway.
What does IT support cost for a wealth management firm in Nassau County?
The monthly per-user fee is set after an assessment, and scope, not a published rate, decides it. Headcount and devices, the number of offices, whether you need archived business texting, broker-dealer or DFS requirements, the depth of Regulation S-P documentation and how many outside platforms you sign in to all move it. One-time projects, such as moving to a new office or replacing a file server with SharePoint, are quoted separately. Nothing is signed for longer than a month.
How do you help Nassau RIAs meet the amended Regulation S-P?
We start with an inventory of every system and service provider that holds customer information, then build the incident response program around it: how an incident is detected, who decides, how systems are contained and restored, and how the 30-day client notice is prepared. Vendor contracts are checked for the 72-hour breach notice the rule expects. ThreatDown, Microsoft 365 audit logs and firewall logs provide the detection, and we run a tabletop exercise each year so the plan is tested.
Do you support our CRM, custodian and portfolio platforms?
We support how your people reach them: managed devices, browsers and plug-ins, single sign-on where the platform supports it, multifactor authentication, the network and the data exports you keep. Problems inside a platform go to its vendor, and we open and follow the case. We do not claim to be a platform's support team. When an adviser leaves, we remove access across every platform the same day and record it, which is the evidence examiners look for.
Does NYDFS Part 500 apply to our advisory firm?
It can. Part 500 follows the license, not the office, so a firm or adviser holding a New York insurance producer license to sell annuities or life coverage may be a covered entity, often with a limited exemption for small firms. Where it applies, multifactor authentication for every user, a documented asset inventory and the annual April 15 filing come with it. We help gather the technical evidence; your compliance counsel confirms which sections apply.
