Managed IT Services in Brooklyn, NY
Most Brooklyn companies are small: in 2019, 84.7 percent of the borough's businesses had fewer than ten employees, by the State Comptroller's count. Few of them can carry an IT department. NetSys runs the whole environment for them, from laptops and Microsoft 365 to the network, the backups and every technology vendor on the bill, out of our office on Prospect Park Southwest.
The short answer
NetSys provides managed IT services across Brooklyn, which is all of Kings County, for one fee per user per month. The plan covers NinjaOne monitoring and patching, an engineer-staffed help desk, ThreatDown endpoint protection, Microsoft 365 and Intune administration, tested backups and management of your carriers and software vendors. Our only office is in Park Slope, so engineers come to your Brooklyn office for hardware, network and moving work once remote troubleshooting has been tried. Monitoring and emergency service run 24/7; the help desk is staffed seven days a week from 4 a.m. to 11 p.m. Eastern time. Agreements are month to month.

How managed IT is delivered in Brooklyn
Our office sits at the southwest corner of Prospect Park, so Downtown Brooklyn is about ten minutes away by car, DUMBO and Sunset Park 15 to 20, and Williamsburg or Bay Ridge roughly half an hour. That short trip changes how a managed plan feels day to day. The NinjaOne agent on every machine lets the help desk fix most problems during the first call, and the engineers who answer are the same people who come out when something needs hands: a dead switch in a Gowanus loft, a new hire's desk in a Fort Greene practice, a Bay Ridge office whose closet has to be rebuilt. Each site gets a named engineer and an account manager with a real cell number, and everything we touch is written into IT Glue, so the next person starts from the record rather than from memory. Monitoring runs 24/7 from Brooklyn, and so does emergency service. Our staffed help-desk hours are 4 a.m. to 11 p.m. Eastern time, seven days a week. The proposal states severe-incident escalation, authorized remediation and any other after-hours work.
One owner for the environment and its vendors
A typical Brooklyn office pays six or seven technology vendors and manages none of them. The internet circuit comes from Verizon Fios, Spectrum Business or Optimum Business, the router was left behind by the landlord, the copier is on a lease, the phones run through a hosted VoIP company, and the core business application has a support line that wants a ticket number before it will talk to anyone. Under a managed plan, those relationships move to us. We keep the account details in IT Glue, open and chase carrier tickets during an outage, sit on the call when the software vendor pushes an update, and check renewal dates before a contract rolls over. Once a quarter your account manager walks through a short roadmap: what was fixed, what is aging out, and what next year's hardware and licensing will cost.
What Brooklyn's biggest sectors need from a managed plan
Education and health services is the borough's largest employment sector, with 289,260 jobs in 2019 according to the State Comptroller, and much of it is outpatient care: physician groups, dental offices, clinics and home-care agencies that need the practice's EHR and billing system up from the first appointment, with HIPAA access controls around it. Nonprofits and social-service agencies need grant-funded laptops tracked and case or donor data kept away from volunteers. Creative studios and young tech firms in the Brooklyn Tech Triangle, which takes in Downtown Brooklyn, DUMBO and the Navy Yard, live in shared drives and very large files. Contractors need tablets and plan sets that work on the job site. Distributors and light manufacturers in Sunset Park and East New York run an ERP or an accounting and inventory platform, often on a server near the loading dock, and property managers depend on a cloud property-management platform and its payment portal.
Your first 30 days on a NetSys plan
Week one is discovery in person. An engineer walks the office, labels the closet, interviews whoever has been looking after IT, and moves every shared password into Keeper, while NinjaOne goes onto each device. Week two switches on the protections: ThreatDown on the endpoints, Barracuda on email, Entra ID Conditional Access so sign-ins from unmanaged devices are challenged, and a first backup proven by restoring a real file. In weeks three and four, laptops are enrolled in Intune, the outgoing provider's remote tools come off, and staff learn the one phone number, email address and Teams channel that reach the help desk. On day 30 you receive a written baseline with a dated replacement list: any PC still on Windows 10, which lost Microsoft support on October 14, 2025, and any server on Windows Server 2016, whose extended support ends January 12, 2027.
What moves the monthly fee for a Brooklyn business
The fee is per user and set after we have seen the environment, so two Brooklyn firms with the same headcount can land in different places. Servers kept on site take more looking after than files in SharePoint. A second location, say a shop in Williamsburg and an office in Downtown Brooklyn, adds a network and a closet to manage. Compliance adds documentation time, whether that is a HIPAA risk analysis for a practice or evidence for an insurance broker regulated under 23 NYCRR Part 500. Freelancers and seasonal staff who need accounts and devices raise the count. Keeping an internal IT person and splitting the work with us lowers the scope. Hardware, licenses and one-off projects such as an office move are quoted separately, in writing, before any of that work starts.

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.

What managed IT costs in Brooklyn
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: Brooklyn practices, nonprofits, studios, contractors and distributors with 10 to 75 employees, often in a loft or mixed-use building, on Microsoft 365 or ready to move there, with no internal IT or one person covering it on the side.

Managed IT services in Brooklyn: FAQs
Do you provide on-site managed IT in Brooklyn?
Yes. NetSys is based at 1 Prospect Park SW, Suite 6E, Brooklyn, NY 11215, and on-site work anywhere in the borough is part of a managed agreement. Most tickets are closed remotely first, often during the first call, because that is quickest for you. Engineers come to the office for jobs that need hands: replacing a firewall or access point, cabling and closet cleanup, setting up new hires, swapping failed hardware and moving offices. Severe problems such as ransomware, a down server or a dead internet circuit go straight to your dedicated engineer.
What is included in a managed IT plan for a business in Kings County?
The same plan applies anywhere in Kings County, from Greenpoint to Sheepshead Bay. It includes 24/7 NinjaOne monitoring with scheduled patching, the engineer-staffed help desk, ThreatDown managed detection and response, Barracuda email protection, KnowBe4 security training, Keeper password management, Microsoft 365 and Intune administration, Datto or Veeam backups with restore tests, IT Glue documentation, vendor and carrier management, and a quarterly roadmap meeting with your account manager. Hardware, licensing and projects are quoted separately.
How do we switch from our current IT provider without losing access?
We plan the handover before anyone is asked to stop. The checklist covers global admin rights in Microsoft 365, the domain registrar and DNS, firewall and Wi-Fi credentials, backup consoles, software licenses and any vendor portals the old provider controls. Both sets of tools run side by side for a short overlap while we confirm every credential works, and then the outgoing provider's agents and accounts are removed. Most staff notice only the new help desk number. For an office of about 20 people the cutover typically takes three to four weeks.
Can NetSys work alongside our in-house IT person?
Yes. In a co-managed arrangement your person keeps the relationships, the knowledge of your business applications and the day-to-day requests, and NetSys takes the monitoring, patching, security stack, backups and the calls that arrive at 5 a.m. or on a Sunday. The split is written into a responsibility matrix, so a ticket never sits between two owners. The same arrangement covers a vacation, a parental leave or the gap after an IT manager resigns, without a rushed hire.
Which New York rules does a managed IT plan help us meet?
Every business holding New Yorkers' private information falls under the SHIELD Act. General Business Law 899-bb asks for reasonable administrative, technical and physical safeguards, and 899-aa now requires notice to affected residents within 30 days of discovering a breach, with notice to the Attorney General, the Department of State and the State Police. Medical and dental practices add the HIPAA Security Rule. A managed plan produces the evidence those rules expect: access records, patch history, backup tests and training completion. This is general information, not legal advice.
