Managed IT Services in New York City
NetSys runs IT for small and mid-sized businesses in New York City: help desk, security, backups, Microsoft 365 and the network, for a flat monthly fee per user. We have run IT out of New York since 1998, and our engineers hold degrees in electrical and computer engineering. Our office is at 1 Prospect Park SW in Brooklyn, so Park Slope to the Financial District is 25 minutes, Midtown 35 to 45, Long Island City 40 and Flushing about an hour, by subway or car; engineers come to you for the work that needs hands, and monitoring and help desk run remotely around the clock. Most clients run between 10 and 75 seats, and every agreement is month to month.
The short answer
NetSys provides managed IT to businesses in New York City: help desk with engineers on the line, 24/7 monitoring, patching, ThreatDown managed detection and response, Microsoft 365 and Intune administration, tested backups and vendor management, for a flat monthly fee per user. Engineers come to you for the work that needs hands; monitoring and help desk run remotely around the clock from our Brooklyn office. Most clients run between 10 and 75 seats, and every agreement is month to month.
How managed IT is delivered in New York City
Our office is at 1 Prospect Park SW in Brooklyn, so Park Slope to the Financial District is 25 minutes, Midtown 35 to 45, Long Island City 40 and Flushing about an hour, by subway or car; engineers come to you for the work that needs hands, and monitoring and help desk run remotely around the clock. The buildings decide a lot of the design. Older Class B and C buildings in Midtown and the Garment District often have one carrier in the riser and no redundancy, co-working floors mean you do not control the network your staff sit on, and landlord-managed risers slow every cabling job, so failover, endpoint policy and building access rules are planned before cutover day rather than discovered on it. The carriers we see most in New York City are Verizon Fios, Spectrum Business and Lightpath, and the failover design starts with which of them actually reach your building.
Who managed IT in New York City is built for
Most of our New York City work sits in Midtown, the Financial District, Long Island City, Downtown Brooklyn and Flushing: law firms on NetDocuments, accounting practices on CCH Axcess, medical and dental groups on eClinicalWorks, financial and advisory firms on Redtail CRM, importers and distributors on NetSuite, and nonprofits on Blackbaud Raiser's Edge. Each carries its own compliance load, which the section below covers, and each has a line-of-business vendor we coordinate with rather than work around. Companies with an internal IT person fit too; in that case we supply the monitoring, the security stack and the after-hours coverage behind them, and they keep their projects.
What tends to go wrong in New York City
Two things shape the continuity design here. First, the weather and the grid: a single building circuit and a flooded basement telecom room are the outages that actually happen here, so ISP failover and off-site backups matter more than storm planning. Second, the attacks that actually land locally are ordinary ones, and the public record shows how they go: the June 2021 intrusion into the New York City Law Department's systems, disclosed by the city, which traced back to a single account without multifactor authentication. The controls in the next section are the ones that would have changed those stories.

A 22-person accounting practice in Flushing
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.
A accounting practice in Flushing with 22 staff across the office and remote, CCH Axcess in the cloud, a file server nobody wants to touch and laptops bought one at a time from a retailer. A cyber insurance renewal arrived with a questionnaire nobody can answer. The antivirus came bundled with the hardware, the Wi-Fi password is shared with visitors, and the monthly IT spend is spread across three vendors none of whom is accountable for the whole.
- Intune enrollment for every laptop and phone, with Windows Autopilot registration for new hardware and a compliance policy that gates access to email and files
- Cisco Meraki firewall and switches configured with segmentation for servers, staff, printers and guests, and a cellular failover circuit
- Cutover in stages over three to four weeks, with the old provider's access removed at the end and no downtime during business hours
- NinjaOne RMM agents deployed to every workstation and server for 24/7 monitoring, patching and remote support
- Barracuda Email Protection placed in front of the mailboxes and SPF, DKIM and DMARC corrected so the company's own domain cannot be spoofed
- KnowBe4 onboarding for every user, with a baseline phishing test in week one and recurring training after that
The help desk answers, the monitoring is watched by a person, the backups restore on schedule and every new hire is set up the same way. The business gets one number to call and a written picture of what is covered. Month to month, like every NetSys agreement.
Complete managed IT, cybersecurity and help desk for a 20-seat organization
A 20-seat organization handed NetSys the whole of its IT. Devices, network, Microsoft 365 and vendors came under one agreement with 24/7 monitoring and a named account manager; endpoint protection, multifactor authentication, email protection and tested backups went onto all twenty seats; staff got a help desk with engineers on the other end; and every new hire now goes through a defined onboarding process with recurring phishing training. The write-up is limited to the scope delivered, with no outcome figures claimed.
Compliance in New York City: the SHIELD Act and what sits on top of it
If you hold personal information on a resident of New York, the New York SHIELD Act (General Business Law § 899-bb) requires any business holding private information on a New York resident, with no employee-count threshold, to keep reasonable administrative, technical and physical safeguards, and § 899-aa sets the breach-notification duty. Small businesses get a scaled standard, not an exemption. Licensed financial businesses add NYDFS Part 500 (amended in November 2023, with multifactor authentication, asset inventories and annual certification now expected of nearly every covered entity). Healthcare practices layer HIPAA on top, and advisory firms answer to the SEC and FINRA. The managed agreement produces the evidence those rules ask for as a by-product: access reviews, patch reports, backup test results and a written incident response plan. Most firms we take over have none of it documented, which is the part that matters if you ever have to demonstrate compliance, so the documentation is built during onboarding rather than sold as a separate project.
What managed IT costs in New York City
Managed IT is priced per user per month for a fully managed agreement, and the number moves with four things more than with headcount: how many servers you run, whether you need after-hours coverage beyond monitoring, how much compliance documentation you carry, and whether we are co-managing alongside an internal person or running everything. We quote from an assessment, not a phone call, and the agreement runs month to month. What belongs in the monthly fee versus what is billed separately is set out on our managed IT pricing page.
Who this fits, and who it does not
Best fit: 10 to 75 employees, one or two offices plus remote staff, already on Microsoft 365 or ready to move there, and either no internal IT or one person who is underwater.
Not a fit: businesses under five people, who are usually better served by the small-office baseline described in our five-person case study, or organizations over 250 seats, which need an internal team we can co-manage with rather than replace.

Managed IT Services in New York City: FAQs
How much do managed IT services cost in New York City?
The figure is quoted per user per month from an assessment of your environment, and it moves with server count, after-hours coverage, compliance requirements and whether you keep an internal IT person more than with headcount. Our managed IT pricing page explains what sits inside the monthly fee and what is billed separately, so quotes can be compared on the same basis.
What happens to our current provider?
We run the transition. That means collecting credentials and documentation, auditing what is actually deployed against what you are paying for, and cutting over in stages. Three to four weeks is typical for a 20-seat office, with no downtime during business hours, and the old provider's access is removed at the end.
What tools do you use to manage our systems?
NinjaOne for remote monitoring and management, IT Glue for documentation, ThreatDown for managed detection and response, Microsoft Defender for Business, Intune and Entra ID for devices and identity, Barracuda for email protection, Datto or Veeam for backups, KnowBe4 for training and Keeper for passwords. Licensing for those tools is included in the agreement rather than added on.
Do you have an office in New York City?
Our office is at 1 Prospect Park SW, Suite 6E, Brooklyn, NY 11215, and Park Slope to the Financial District is 25 minutes, Midtown 35 to 45, Long Island City 40 and Flushing about an hour, by subway or car. Engineers come to you for anything the help desk cannot fix remotely, and monitoring runs around the clock from Brooklyn. Every agreement is month to month.
Does the NY SHIELD Act apply to a small business?
Yes. It applies to any business holding private information on a New York resident, with no employee-count threshold. Small businesses get a scaled standard, meaning safeguards appropriate to their size, but not an exemption, and the breach-notification duty under § 899-aa applies to everyone.
