IT Support and Managed IT Services in Westchester County
NetSys provides IT support and managed IT to Westchester businesses, with remote management and on-site engineering from its Brooklyn headquarters. For a single office or a team spread between the county and the city, the useful question is who owns each system, what needs a visit and how support escalates.
The short answer
NetSys provides IT support and managed IT services across Westchester County for professional firms, medical and dental practices, and multi-location operators from Yonkers to Mount Kisco. The county sits inside our on-site corridor, so visits are routine scheduling; the response-time table is on our managed IT services page. Pricing is per user per month, shaped by sites and visits.

The corridor we drive every week
Westchester isn't an outpost for us. It's the corridor between our Brooklyn headquarters and our Hudson Valley coverage area. That geography means on-site work in White Plains, New Rochelle, Yonkers, Larchmont, or anywhere else in the county is routine scheduling, not a special trip, while support and 24/7 monitoring run remotely like they do for every NetSys client.
Real Westchester work
One of our multi-location clients, UBX Fitness, whose locations include Larchmont, came to us with technology and security spread across vendors and nobody owning the whole picture. We reviewed their Microsoft 365 accounts, network security, endpoint protection, and backups, prioritized the risks most likely to interrupt operations, and documented their recovery process. Their COO's assessment of that work is below, in his own words.
Who this fits
Westchester professional firms, medical and dental practices, fitness and retail operators with more than one location, and any business that has outgrown reactive break-fix IT. If you already have an IT person, co-managed IT adds 24/7 coverage and security depth behind them.
Scarsdale, Rye, Harrison and Purchase
These towns hold many of the county's advisory practices, family offices, law firms and accountants, often teams of 3 to 25 people. Attackers go after their clients' money by impersonating principals and forging payment instructions, so we pair hardened identity and monitored endpoints with payment steps that need a call to a known number. Staff who split the week between the office, Manhattan and home get managed devices and Conditional Access that work wherever they sign in. Around the corporate headquarters campuses in Purchase, enterprise clients send smaller firms security questionnaires, and we build the evidence those ask for: documented controls, dated access reviews, tested restores and an incident plan with an owner.

“Before working with NetSys, our technology and cybersecurity systems were spread across different vendors, and nobody had full responsibility for the environment. NetSys reviewed our Microsoft 365 accounts, network security, endpoint protection and backup systems, then created a prioritized plan around the risks most likely to interrupt operations. They improved account security, documented our recovery process and gave leadership a clear picture of what was protected and what still needed attention.”

NetSys vs. XSolutions
XSolutions ranks on the first page for IT services in Westchester County. Their column below is drawn from their own published pages and links to each source. Ours states what we publish. Put the same questions to both.
| The NetSys Group | XSolutions | |
|---|---|---|
| Agreement | Month to month. Leave any time, no early-exit penalty. | Their New City page publishes a 60-day satisfaction guarantee and a one-month onboarding commitment. (xsolutions.com) |
| What the monthly fee covers | One agreement: AI services, cybersecurity, managed IT with help desk, PAM, PIM and disaster recovery planning. | Their New City service page itemizes the package across four groupings: cybersecurity (24/7 SOC monitoring, AI-powered endpoint protection, managed firewall, dark web and phishing scanning, awareness training), unlimited tech support (live answer, unlimited remote support, vendor liaison, discounted project pricing), IT compliance and continuity (24/7 network health monitoring, encrypted backups, security patch management, email and spam filtering), and IT strategy (quarterly IT health and compliance reviews, tech budgeting and asset reporting). (xsolutions.com) |
| Privileged access and credentials | PAM and PIM in the base agreement, each with a published service page describing the work. | We could not find privileged access, privileged identity management or managed credentials named on their site. |
| AI and automation | In-house practice led by Jamie Baum: readiness assessments, Copilot rollouts, custom agents and workflow automation. | Their home page lists 'AI Usage Guidance' among their services, described as helping employees use AI tools safely, and their New City page offers an AI-Powered Tech Efficiency Assessment. (xsolutions.com) |
| Disaster recovery | A written plan plus restores that are performed and timed. More than 30 ransomware incidents handled in three years, every one recovered. | Their Backup & Disaster Recovery page publishes five components, image-based backup, onsite failover, cloud redundancy in geographically dispersed data centers, bare metal restore, and daily backup verification, and lists untested backups among the recovery gaps it describes. (xsolutions.com) |
| Who answers | A NetSys engineer, plus a named account manager who gives you a real cell number. | Their New City page publishes a live-answer guarantee, unlimited remote support, a vendor liaison, an after-hours on-call coordinator, and 24/7 SOC and network monitoring. (xsolutions.com) |
| Response commitments | Written into the agreement rather than implied on the website. | Their New City service page states support tickets are answered in under 15 minutes and that a field technician is dispatched from the New City office typically within one business hour when remote remediation is not sufficient. (xsolutions.com) |
| Proof before you commit | The free assessment is a remote external penetration test, limited to the information available to NetSys and the external scope we agree with you. | Their New City page offers three free pre-engagement evaluations: a network security assessment, a cybersecurity insurance audit, and an AI-powered tech efficiency assessment. (xsolutions.com) |
| Where they are | One office, in Brooklyn. On-site across New York City, Long Island, Westchester, the Hudson Valley, North Jersey and Fairfield County, CT, with remote managed IT nationwide. | Their site publishes one street address, 20 Squadron Blvd., STE 320, New City, NY 10956, and names a service area covering Rockland, Westchester, Orange and Putnam counties in NY, Bergen, Essex, Passaic and Hudson counties in NJ, and CT.

Westchester County FAQs
What should a Westchester business confirm about on-site coverage?
Identify the work likely to require a visit, the locations involved and how urgent incidents are escalated. Ask which visits are included, how project work is scoped and who coordinates with the building or carrier. Confirm arrangements in the agreement rather than assuming a town name implies a fixed arrival time.
Can the scope cover our internal IT person and a New York City office?
Yes. A co-managed arrangement can divide user support, security, infrastructure and projects between your staff and NetSys. Name the owner for each shared system and agree how an issue moves between teams. Include both locations in the inventory and escalation plan.
Do you come on-site in Westchester County?
Yes. Westchester sits between our Brooklyn headquarters and our Hudson Valley coverage area, so on-site engineer visits are routine across the county. The free external penetration test that usually opens the relationship runs remotely.
Is NetSys an IT company that serves Westchester County businesses?
Yes. NetSys is an IT services company that supports Westchester County businesses from its one office, in Brooklyn: managed IT support, an engineer-led help desk, cybersecurity and IT consulting under one month-to-month agreement. Westchester is inside our on-site coverage, so engineers come to your office for work that needs hands. The help desk is staffed seven days a week from 4 a.m. to 11 p.m. Eastern, and monitoring and emergency service run 24/7.
Do you have Westchester clients today?
Yes. Our client base includes a multi-location fitness operator with a Larchmont location, and their COO's testimonial is on this page. Like all of our clients, they're on month-to-month terms.
Can you support a business with locations in Westchester and the city?
That's our home geography: Brooklyn HQ, the Westchester corridor and Hudson Valley coverage. Multi-site connectivity and consolidated security are core to our practice; our published medical case study runs seven connected locations.
Which Westchester towns do you cover?
All of them. New Rochelle, Larchmont, Mount Vernon, Mamaroneck, Scarsdale, Rye, Harrison and the rest of the county sit inside the corridor our engineers already drive between Brooklyn and the lower Hudson Valley. White Plains, the county's commercial center, and Yonkers have pages of their own, and this page covers Scarsdale, Rye, Harrison and Purchase in the section above.
Do you cover Edgemont and other Scarsdale addresses?
Yes. Edgemont is an unincorporated part of the Town of Greenburgh, not the Village of Scarsdale, though much of it shares Scarsdale's 10583 ZIP code. It sits inside our Westchester County on-site coverage along with Hartsdale, Eastchester and the village's own neighborhoods, such as Fox Meadow, Quaker Ridge and Greenacres. Offices at any of those addresses get the same scheduled visits and agreement terms.
Do you cover Rye Brook and Port Chester as well as the City of Rye?
Yes. The City of Rye is its own municipality, while Port Chester and Rye Brook are villages in the separate Town of Rye, along with the Rye Neck section of Mamaroneck. All of them sit inside our Westchester County on-site coverage, so offices on Purchase Street, along Westchester Avenue or near the Port Chester waterfront get the same scheduled visits.
Is Purchase part of Harrison?
Yes. Harrison is a town and a village with the same boundaries, and Purchase and West Harrison are hamlets inside it, so a Purchase or West Harrison address is still Harrison. We cover all of it, including the office buildings along Westchester Avenue, as part of our Westchester County on-site coverage.
What does business IT support in Westchester include?
The same coverage every NetSys client gets, aimed at the shapes Westchester businesses tend to take: a head office plus a warehouse or a second branch, staff who commute in and work from home part of the week, and a Microsoft 365 tenant nobody has reviewed since the day it was set up. So: helpdesk and patching, endpoint and email security, multifactor authentication and Conditional Access, site-to-site connectivity between your locations, and backups with recovery times we test rather than assume. On-site engineers cover the county, your account manager's cell number is a real one, and the agreement runs month to month.
Do you handle cybersecurity for Westchester businesses, not just IT support?
Security is the core of the practice, not an add-on, and the quote further down this page is a client describing that work rather than a line we wrote for him. Topaz R. is COO of a multi-location fitness operator with a Larchmont location, and what he credits us with is unglamorous and specific: tightening account security, telling leadership plainly what was covered and where the gaps still were, and putting a recovery process in writing where it could be checked. That is what the opening of a Westchester engagement looks like. Where an organization needs more, the same relationship extends into penetration testing, readiness work ahead of a cyber-insurance renewal, and vCISO leadership for a company that can't justify hiring a security executive outright.
Do you provide managed IT services in Yonkers?
Yes. Yonkers is inside the Westchester corridor our engineers already work, so on-site visits there are routine scheduling from our Brooklyn office. Yonkers businesses get the same managed service as the rest of the county: help desk, Microsoft 365, endpoint and email security, patching and backups with tested restores, all on month-to-month terms.
Is 24/7 IT support available for Westchester businesses?
Monitoring is 24/7 for every managed client, so a failed backup or a security alert is seen at night rather than the next morning. The help desk is staffed seven days a week from 4 a.m. to 11 p.m. Eastern time, and emergency service is available 24/7. Severe-incident escalation and any paid after-hours work are written into the agreement separately. We would rather put those terms in writing than let a slogan imply them.
How much do managed IT services cost in Westchester County?
Managed IT here is priced per user per month, with no published rate card because the scope decides it. The number of users and devices, servers, how many Westchester sites you run, compliance needs such as HIPAA, and expected on-site time all move the price. Projects like an office move are quoted separately.
What does the NY SHIELD Act require of Westchester businesses?
The SHIELD Act applies to any business holding private information about New York residents. GBL §899-bb requires reasonable administrative, technical and physical safeguards scaled to your size, and GBL §899-aa sets the breach-notification duties. We build and document the technical safeguards for you. This is general information, not legal advice.
How do we choose a managed IT provider in Westchester County?
Ask every provider the same questions and compare the written answers: what the monthly fee includes, which on-site visits are covered, how restores are tested, who holds your admin credentials and how you would leave. Check that engineers actually work the county. Month-to-month terms let you test the answers after you sign.
