Manufacturing IT Support on Long Island
Long Island still makes things: defense electronics in Greenlawn, aerostructures in Edgewood, and precision machining, electronics assembly and fabrication across the Hauppauge Industrial Park and the Route 110 corridor. Many of those shops sit two or three tiers down a defense supply chain. NetSys supports the ERP, the shop-floor network and the security requirements that come with that work.
The short answer
NetSys provides manufacturing IT support on Long Island: help desk and device management for office and plant staff, an ERP environment that stays patched and backed up, shop-floor machines on their own network segments, ThreatDown detection and response, and the NIST SP 800-171 controls defense subcontractors need for DFARS work and CMMC. Plants in Nassau and western Suffolk, Hauppauge included, are inside our on-site area, with engineers driving out from Brooklyn; Patchogue and Port Jefferson are 50 to 60 miles away, so we confirm drive time first, and East End sites are supported remotely. Pricing is per user per month on month-to-month terms.

What changes for a Long Island manufacturer
The Island's industrial base is smaller than it was in the Grumman years, but it is dense and still tied to defense. In June 2023 a congressional office announced Navy and Coast Guard contract work for BAE Systems in Greenlawn and for Advanced Acoustic Concepts in Hauppauge, and Empire State Development has backed CPI Aerostructures' expansion in Suffolk, where it builds structural parts for fixed-wing aircraft and helicopters. Below those names sit machine shops, electronics assemblers, sheet metal fabricators and finishing houses, many of them in the Hauppauge Industrial Park. Those smaller firms receive drawings marked CUI, purchase orders carrying DFARS clauses, and supplier questionnaires asking for an SPRS score. Their IT has usually grown in layers: an ERP server installed a decade ago, CNC controllers, inspection PCs and the front office on one flat network, a Windows 10 machine kept alive for one piece of equipment, and a single cable circuit into the building. The work is untangling that without stopping production or losing the program files that run the machines.
On-site and remote support for plants and offices
Office users, estimators and planners get the same help desk as anyone: password resets, Microsoft 365, printers, a laptop that will not reach the ERP from home. The plant is different. A CNC programming station, a coordinate measuring machine PC or a barcode terminal at shipping may need someone standing next to it, so engineers drive out from Park Slope, roughly an hour to Farmingdale or Bethpage and 70 to 90 minutes to Hauppauge, to run cable to new equipment, replace a switch in a dusty closet, rebuild an inspection PC or install access points over the floor. We schedule plant work around shifts and changeovers. Severe problems, such as a stopped ERP, ransomware or no internet, go straight to your dedicated engineer, and the written commitment for critical issues is a ten-minute phone response and a thirty-minute remote response.
The ERP, the shop floor and the network between them
We separate the plant from the office before anything else. Machines, controllers, inspection stations and the PCs that feed them program files move onto their own network segments behind a Fortinet or Meraki firewall, with rules that let the ERP and file transfers through and nothing else. Older PCs that cannot be upgraded lose internet access and get application allowlisting. Then the dates: Windows 10 support ended October 14, 2025, and Windows Server 2016 extended support ends January 12, 2027, which catches many on-premises ERP and file servers. We plan those upgrades with your ERP vendor and test the database restore before cutover. New office laptops ship through Intune and Windows Autopilot, so a replacement arrives ready to work. Program libraries, quality records and drawings are backed up separately, because losing the files that run the machines stops a line as surely as losing the ERP.
Keeping lines running through storms and attacks
The August 18 and 19, 2024 storm that the governor called a 1-in-1,000-year rain event flooded parts of Commack and Brookhaven and closed Route 25A; four years earlier Isaias cut power to hundreds of thousands of Long Island customers. Plants need battery backup sized for the network core and the ERP server, cellular failover for the circuit, and a plan that says which machines can keep running without the network. Ransomware is the bigger risk for manufacturers, who are targeted because downtime is expensive. Suffolk County learned in 2022 what end-of-life firewalls and months of unnoticed access lead to. We patch on a schedule, watch endpoints 24/7 with ThreatDown, keep immutable Datto or Veeam copies and restore the ERP database as a test. NetSys has handled more than 30 ransomware incidents in three years, and every one was fully recovered.

Compliance rules for Long Island manufacturers
DFARS 252.204-7012 and NIST SP 800-171 Revision 2
A defense subcontract that involves controlled unclassified information carries DFARS 252.204-7012, which requires the 110 security requirements of NIST SP 800-171 Revision 2, a report to DoD within 72 hours whenever a cyber incident is discovered, and flow-down to your own suppliers who handle CUI. Under the related DFARS assessment clauses, a current self-assessment score must be posted in SPRS. We write the System Security Plan and plan of action, then keep the score honest.
CMMC: what still applies after July 13, 2026
CMMC Phase 2 was suspended by the Department of War on July 13, 2026, so third-party Level 2 certification will not be required for contract awards from November 10, 2026 as planned, and Phases 3 and 4 are on hold. A CMMC Reform Task Force is reviewing the program; its report had not been made public as of late October 2026. Level 1 and Level 2 self-assessments and SPRS affirmations remain in force, so primes will keep asking for them.
SHIELD Act duties for plant and payroll data
Manufacturers hold private information too: payroll files, employee Social Security numbers and customer card data. Section 899-bb requires reasonable administrative, technical and physical safeguards for it, scaled for smaller businesses, and 899-aa requires notice to affected New Yorkers within 30 days of discovering a breach, plus notice to the Attorney General, the Department of State and the State Police.

Manufacturers in Long Island: FAQs
Who provides IT support for manufacturers on Long Island?
NetSys does. Plants and offices in Nassau and western Suffolk get engineers on site from our Brooklyn office, and East End operations are supported remotely. We handle the office and the plant: help desk, Microsoft 365, ERP servers and backups, shop-floor networks, security and the documentation defense customers ask for. Your ERP and machine vendors keep application support, and we coordinate with them. We have run IT for businesses since 1998, and our agreements are month to month.
What does IT support cost for a manufacturer on Long Island?
It is priced per user per month after an assessment. For a manufacturer the inputs include shared plant devices as well as named users, the number of buildings and network segments, whether the ERP runs on premises or in the cloud, backup volume, and whether a NIST SP 800-171 program is in scope. Separating the shop floor, replacing a 2016 server or building a CUI enclave is quoted as a project after scoping.
How do you help Long Island manufacturers meet NIST SP 800-171 and CMMC?
We find where CUI enters and lives, then decide whether to protect the whole company or a smaller enclave, which is often cheaper for a job shop. We write the System Security Plan, score it with the DoD Assessment Methodology, prepare the SPRS submission and work the plan of action: MFA, encryption, logging, ThreatDown, access reviews and training. With Phase 2 suspended, the aim is a defensible self-assessment now and readiness if certification returns.
Do you support our ERP and shop-floor systems?
Yes, at the infrastructure level. We run and patch the servers or cloud hosting behind the ERP, back up and test-restore its database, manage user access, and keep the network between the ERP, the shop-floor terminals and the machines reliable. Configuration, reports and bugs inside the ERP or a machine's control software stay with those vendors; we open the tickets, provide supervised remote access and make sure their changes do not undo your security controls.
What should we do with machines that still run Windows 10 or older?
First, list them and what each one controls. Windows 10 stopped receiving security updates on October 14, 2025, but a PC that drives a machine tool often cannot be upgraded without the machine builder's support. Those PCs get isolated on their own segment with no internet, controlled USB ports, application allowlisting and a disk image backup, so a failure means a reload rather than a crisis. Office PCs that can move to Windows 11 should move.
Can you separate the shop floor from the office network without downtime?
Yes, in stages. We map every device and conversation first, so we know which machines talk to the ERP, the file server or a vendor's remote support tool. Then we build the new segments and firewall rules alongside the old network and move devices over in planned windows, a cell or a line at a time, usually at shift change or on a weekend. The rollback for each move is written down before we start it.
