Manufacturing IT Support in Westchester County, NY
Westchester has fewer manufacturers than law firms, but they depend on IT just as much: rail car assembly in Yonkers, production and suppliers inside the county's biosciences cluster, and headquarters that run plants in other places. NetSys supports their offices, ERP systems and shop-floor networks from Brooklyn, and our engineers drive up when a plant needs hands-on work.
The short answer
NetSys provides manufacturing IT support in Westchester County: managed IT for the office and the ERP, segmented networks that keep shop-floor PCs and machines apart from email and the internet, ThreatDown endpoint protection, Datto and Veeam backups of production data, Windows 10 and Windows Server 2016 replacement projects, and NIST SP 800-171 documentation for defense suppliers. Plants and offices across the county are within our on-site radius, so engineers handle network, hardware and cutover work in person once remote diagnosis is done, all on month-to-month terms.

Manufacturing in a county known for offices
Westchester built a manufacturing base in the nineteenth century along the Hudson and the Nepperhan in Yonkers, and part of it survives. Kawasaki Rail Car's 150,000-square-foot plant on Wells Avenue in Yonkers, open since 1986, assembles and tests new rail cars and overhauls old ones. The county's biosciences cluster, the largest in New York State with about 8,000 jobs by the county's 2021 count, includes manufacturers and supply-chain companies alongside the research labs. Beyond those, the base is smaller and more varied, and company headquarters such as PepsiCo's in Purchase manage production sites in other places from offices here. That mix shapes the IT work. A plant in the county is often an older building with thick masonry walls, a single carrier and machines tied to Windows versions nobody can upgrade, while the office next to it runs Microsoft 365 and a current ERP. The job is to connect the two without letting a problem on one side stop the other, and to keep production records recoverable when the building is not.
Support on the plant floor and from Brooklyn
Every plant in the county is within our on-site radius. Yonkers plants are about 45 minutes from Park Slope without traffic and sites further up the Saw Mill and Hudson corridors take longer, so visits are planned with your production calendar, not against it. Remote work comes first: NinjaOne monitors servers, switches and PCs, patches office machines on a schedule and alerts an engineer when a production PC's disk fills or a backup fails. Help desk staff start at 4 a.m. Eastern and stay until 11 p.m., every day, which covers an early first shift, and emergency service runs 24/7 for a down server or a ransomware alert. Engineers come on site to install switches and firewalls, run new network drops to machines, replace aging shop-floor PCs and cut over to new servers during a planned shutdown.
The ERP, the shop floor and the network between them
Most manufacturers run an ERP for orders, inventory and costing, often with its database on a local server, plus quality, labeling and shipping systems, and shop-floor PCs attached to machines, scales or test rigs. Those PCs are the weak point. Many still run Windows 10, unsupported since October 14, 2025, or an even older version tied to the machine's software, and the servers beside them may be on Windows Server 2016, whose extended support runs out on January 12, 2027. Where a PC cannot be upgraded we isolate it: its own network segment on the Fortinet or Meraki firewall, no email or web browsing, remote access only through a controlled path, and application allow-listing so only the machine's software runs. The ERP server is backed up with Datto or Veeam and test-restored, and the ERP vendor keeps application support while we handle the server, the network and the users.
Storms, power and keeping production records
Weather has stopped more Westchester operations than attackers have. The remnants of Ida flooded low-lying parts of the county in September 2021 and led to a federal disaster declaration, while Isaias in August 2020 left some areas waiting a week or more for power to be fully restored. A plant cannot ride that out on a UPS, so we plan what keeps running: ERP and order data replicated to the cloud so the office can ship and invoice from elsewhere, production records and drawings in SharePoint, and network gear on battery long enough to shut down cleanly. Ransomware is the other stoppage risk, and a plant's cost of downtime makes it an attractive target, so endpoint detection, offline backups and segmentation between office and floor are standard. The published importer case study shows the same planning after a storm cut a company off for days.

Rules for Westchester manufacturers
NIST SP 800-171 and CMMC for defense suppliers
Suppliers handling controlled unclassified information for the Department of War must meet DFARS 252.204-7012 and the 110 requirements of NIST SP 800-171 Revision 2, and keep a current SPRS score with an affirmation. On July 13, 2026 the Department suspended CMMC Phase 2, the third-party Level 2 certification due to begin November 10, 2026, while a reform task force reviews the program. Level 1 and Level 2 self-assessments remain in force, so the documentation work continues.
Windows lifecycle dates
Microsoft's lifecycle pages put the end of Windows 10 support at October 14, 2025 and the end of Windows Server 2016 extended support at January 12, 2027. Running unsupported systems is not illegal, but insurers ask about them, NIST SP 800-171 expects system flaws to be identified and corrected in a timely manner, and a machine that cannot be patched needs written compensating controls such as isolation and allow-listing.
SHIELD Act and payroll records
Employee Social Security and driver's license numbers, payroll bank account details and any username paired with a password are private information under New York law. The Act expects reasonable safeguards, including a risk assessment, staff training, vendor oversight and secure disposal of old drives, and when a breach exposes that data, the affected New Yorkers are owed notice within 30 days of the company discovering it.

Manufacturers in Westchester County: FAQs
Who provides IT support for manufacturers in Westchester County?
NetSys, a Brooklyn IT company that sends engineers to plants and offices throughout Westchester. For manufacturers we manage the office environment and Microsoft 365, the servers behind the ERP and quality systems, the network and firewalls that separate the shop floor from the office, endpoint security, and backups with timed restores. The team holds Cisco and Microsoft certifications, the agreement can be ended month to month, and one account manager stays responsible for your company.
Do you provide on-site IT support for manufacturers in Westchester?
Yes. Our engineers work on site at plants and offices throughout Westchester: switch and firewall installs, new network drops to machines, shop-floor PC replacements, server cutovers during a planned shutdown and wireless surveys of the production area. Remote monitoring and the help desk solve most problems first, which keeps production moving. If ransomware hits or the ERP server goes down, your dedicated engineer takes the call personally and judges whether a trip to the plant is the quickest fix.
What does IT support cost for a manufacturer in Westchester County?
The fee is per user per month, set after an assessment that, for a manufacturer, also counts shop-floor PCs and network devices that have no named user. The price moves with office headcount, the number of servers and production machines on the network, how many buildings you run, whether you need NIST SP 800-171 documentation, and how often the plant needs a visit. Network segmentation, server replacements and ERP migrations are quoted as projects after scoping.
How do you help Westchester manufacturers meet NIST SP 800-171?
We start by finding where controlled unclassified information actually enters and lives, then shrink that footprint into an enclave of managed devices, accounts and storage. Next comes the system security plan, which describes how each of the 110 requirements is met, a plan of action for the gaps, and the evidence behind your SPRS score. CMMC Phase 2 third-party certification is suspended as of July 2026, but DFARS 252.204-7012 and self-assessments still apply, so primes keep asking for the score.
Do you support ERP systems for manufacturers?
We support the infrastructure an ERP runs on: the Windows or SQL server, its backups and restore tests, user access and multifactor sign-in, remote access for staff and reps, label and document printers, and the network between the office and the floor. Application questions, customizations and version upgrades of the ERP itself stay with its vendor or reseller, and we coordinate with them, prepare the servers and schedule the cutover. If the ERP still sits on Windows Server 2016, we plan its move before support ends.
Can you secure shop-floor PCs that cannot be upgraded?
Yes, with compensating controls instead of patches. The PC goes on its own network segment that can reach only the machine and the server it reports to, with no email, web browsing or direct internet access. USB storage is blocked or limited, application allow-listing stops unknown programs, and remote access for the machine vendor runs through a controlled, logged path that is off by default. We monitor the segment for unusual traffic and document the exception, so an insurer or a prime contractor can see why the system is acceptable.
