IT Support & Managed IT in Great Neck
Great Neck runs on professional practices — accounting and law offices, medical suites, property managers, family offices — the kind of firms where one person's inbox holds a client's entire financial life. NetSys serves Nassau County clients today and brings Great Neck the same standard: security built for confidentiality, IT that just works, and AI automation that gives small teams hours back.
The short answer
For Great Neck CPAs, law offices, medical suites and family offices, NetSys delivers IT support, security and Microsoft 365 management. Nassau County is an on-site coverage area where we already serve clients, and engineers make the short trip from Brooklyn for work that needs hands. Fees are per user per month, with compliance scope and devices setting the level.
- Nassau County: on-site coverage area with existing NetSys clients
- Confidentiality-first: our financial and fiduciary clients are never named
- HIPAA-aware IT for medical and dental practices
- Month to month — no long-term contracts
- Headquarters: Brooklyn, NY, ~16 miles away
IT for practices where discretion is the product
A Great Neck CPA firm in February, a law office mid-closing, a medical suite with a full waiting room — none of them can absorb downtime, and none of them can afford a data incident that reaches clients. We build for both at once: systems monitored around the clock so failures get caught before the morning rush, and a security stack — MFA, managed detection and response, email defense, immutable backup — that treats client confidentiality as the asset it is.
The peninsula's after-hours problem, solved two ways
Small professional teams miss calls at lunch and after six, and the callers are often new business. Our AI receptionist answers every time, books into your real calendar, and hands genuinely human conversations to a person with context attached. Behind it, the same AI practice automates intake, document filing, and follow-up — for one New York medical practice, about 40 combined staff-hours a week returned. It's the rare technology purchase a five-person office feels by Friday.
Who this fits in Great Neck
Accounting and tax practices, law offices, medical and dental suites, property and real-estate managers, family offices, and the small financial firms that dot Middle Neck Road. If your IT today is one overworked consultant or a relative who's good with computers, managed IT with month-to-month terms is the upgrade that doesn't require faith — we re-earn the agreement every cycle.

An 11-person CPA practice near Middle Neck Road
The specific engagements behind this profile are under NDA, so it is written as a generalization rather than a named client. Our published, client-approved outcomes are in case studies.
Tax season doubled email volume, and one partner just caught a convincing fake e-file confirmation an hour before someone clicked it. The server closet is warm, the backup is a USB drive that goes home on Fridays, and the firm's cyber-insurance renewal now asks questions nobody can answer. The front desk can't keep up with February phones.
- Security assessment with the insurance questionnaire on the table — every fix mapped to a question the carrier asks
- MFA and conditional access across the tenant; email defense tuned for IRS-season phishing and client impersonation
- Managed endpoint detection and response on every machine, monitored 24/7
- Immutable cloud backup replacing the Friday USB drive, with a restore performed and dated
- An AI receptionist answering overflow and after-hours calls, booking consults directly
- WISP and incident-response documentation the firm can hand to its carrier and its own clients
The intended result is a renewal questionnaire answered truthfully with evidence attached, February phone calls that no longer eat partner time, and email defenses built to catch the next convincing fake before a partner has to. Month to month, like every NetSys agreement.

Great Neck, NY FAQs
Do you support accounting and tax practices through busy season?
Yes — and busy season is exactly when the monitoring earns its keep. We schedule maintenance around your calendar, keep restores tested before February rather than during it, and tune email defense for the impersonation attacks that spike at deadlines. Our IRS-security and WISP guidance for accounting firms is published on this site; the same standards run in production for our fiduciary clients across Nassau County.
Is NetSys HIPAA-aware for medical offices in Great Neck?
Yes. We support medical and dental practices with encrypted systems, access controls, audit trails, and the business-associate posture HIPAA requires — and our healthcare pages document the standard. Automation is built the same way: AI intake and patient-communication workflows are designed with compliance in the room, not bolted on after.
What does the free external penetration test involve for a small firm?
The free assessment is a remote external penetration test, limited to the information available to NetSys and the external scope we agree with you. The findings describe what was assessed and its limitations. Onsite work, internal controls and broader assessments require a separate scope.
We're a 6-person office. Are we too small for managed IT?
No — you're the size that benefits most, because one sick computer or one compromised inbox is a sixth of the company. Pricing scales to headcount, agreements run month to month, and the AI automation practice is often where small offices see the fastest payback: phones answered, intake filed, follow-ups sent, without a new hire.
What security rules apply to a Great Neck tax practice?
The FTC Safeguards Rule (16 CFR Part 314) treats tax preparation firms as financial institutions, so a practice needs a written information security program, a Qualified Individual to run it, multi-factor authentication for anyone accessing customer information, and encryption. New York's SHIELD Act also applies. This is general information, not legal advice.
Do you cover the whole Great Neck peninsula, including Lake Success?
Yes. Kings Point, Great Neck Plaza, Great Neck Estates, Kensington, Russell Gardens, Saddle Rock, Thomaston and Lake Success, with its office parks, all fall inside our Nassau County on-site coverage area. Manhasset and Port Washington next door are covered the same way, so a practice that moves across Northern Boulevard keeps the same support.
How should a Great Neck CPA firm share files with clients securely?
Through a controlled channel rather than email attachments: a client portal or Microsoft 365 sharing set to expire links, require sign-in and log every download. We configure the Microsoft 365 or Google Workspace side, enforce MFA for staff, and coordinate with your portal vendor, so tax documents stop living in inboxes.
Can one provider support our Great Neck office and a Queens location?
Yes. Great Neck borders Little Neck and Douglaston in Queens, and both Nassau County and New York City are named on-site coverage areas, so one agreement can cover both offices: shared monitoring, one help desk, and a site-to-site link between networks where the work calls for it.
