Manufacturing IT Support in Fairfield County, CT
Fairfield County still makes things: helicopters in Stratford, lithography systems in Wilton, surgical instruments in Bridgeport and specialty chemicals in Norwalk, with Hubbell's headquarters in Shelton and hundreds of smaller suppliers around them. NetSys runs the IT and security those plants and shops depend on, from Brooklyn, with engineers on site in the lower county.
The short answer
NetSys provides IT support for manufacturers in Fairfield County, CT: the ERP and the server or cloud it runs on, shop-floor PCs and the network that links them to the office, segmentation between production equipment and email, ThreatDown detection and response, tested backups, and NIST SP 800-171 evidence for defense suppliers. Engineers work on site in the lower county, from Stamford and Norwalk to Wilton, Ridgefield and Fairfield; plants in Bridgeport, Stratford, Trumbull and Danbury start with remote support and confirmed drive times, and Shelton and Newtown are supported remotely. Pricing is per user per month.

What changes for a Fairfield County manufacturer
Manufacturing here is mostly suppliers rather than giant plants. Sikorsky employs about 8,000 people in Connecticut from its Stratford headquarters, ASML's Wilton site employs about 1,600 in the county, and Hubbell, Paragon Medical, Bigelow Tea and Vanderbilt Chemicals run operations in Shelton, Bridgeport, Fairfield and Norwalk. Below them are machine shops, finishing firms, electronics assemblers and packaging suppliers, many family-owned, some in former mill and factory buildings near the Housatonic and the Pequonnock. Those buildings bring thick walls that block Wi-Fi, long cable runs and server closets close to the shop floor. Customers bring requirements of their own: defense primes flow down DFARS clauses, medical-device customers want traceability, and every large buyer now sends a security questionnaire. A supplier with 40 people and one office manager doing IT has to answer all of it, which is the gap we fill.
On-site help where the plants are, remote help everywhere else
Fairfield County manufacturing straddles our on-site boundary, so we are specific about it. Plants and offices in Norwalk, Wilton, Stamford, Ridgefield, Westport and Fairfield get on-site work: switch and access point installs on the floor, cabling coordination with your electrician, PC swaps at machine stations and server work. Bridgeport, Stratford and Trumbull are 50 to 60 miles from Park Slope, so we start remotely there and confirm drive time before scheduling a visit. Shelton, Newtown and the northern towns are remote: replacement PCs ship pre-configured through Windows Autopilot, firewalls arrive ready to plug in, and your maintenance staff or cabling contractor connects them while our engineer watches them come online. Day to day, NinjaOne patching and monitoring reach every site the same way.
The ERP, the shop floor and the network between them
Most supplier outages trace back to one of three places: the ERP server, the network between the office and the floor, or a Windows PC running a machine that was never patched because nobody dared reboot it. We document each of them, then fix the riskiest first. The ERP database gets nightly image backups to Datto SIRIS with an off-site copy, so a failed server becomes a restore, not a rebuild. The shop floor goes on its own VLAN behind a Meraki or Fortinet firewall, so a phishing email opened in the office cannot reach a CNC controller or a test station. Machine PCs that cannot be updated are isolated and watched rather than ignored, and Windows Server 2016 machines are scheduled for replacement before extended support ends on January 12, 2027.
Storms, ransomware and keeping orders moving
Two kinds of outage stop a Fairfield County plant. Weather is one: the remnants of Ida in September 2021 brought a federal disaster declaration that included the county, and coastal storms regularly take down lines along the Housatonic and the Sound. Ransomware is the other. In October 2019 Pitney Bowes, then headquartered in Stamford, disclosed a malware attack that encrypted information on some of its systems and disrupted customer access to its services. A smaller supplier hit the same way can lose shipping, invoicing and its ERP at once. We plan for both with battery backup and cellular failover for the network, ThreatDown managed detection and response on every endpoint including engineering workstations, offline backup copies that attackers cannot reach, and a recovery runbook tested before it is needed.

Compliance rules for Fairfield County manufacturers
NIST SP 800-171 and DFARS 252.204-7012
Suppliers handling controlled unclassified information for the Department of War must protect it under NIST SP 800-171 Revision 2, report cyber incidents to the department within 72 hours under DFARS 252.204-7012, and keep a current self-assessment score and affirmation in SPRS. Those duties apply regardless of where certification stands, and primes check them before awarding subcontracts.
CMMC status in late 2026
On July 13, 2026 the Department of War suspended CMMC Phase 2, which would have made third-party Level 2 certification a condition of award starting November 10, 2026, and put Phases 3 and 4 on hold while a reform task force reviews the program; its report has not been made public. Level 1 and Level 2 self-assessments remain in force where contracts call for them.
Connecticut breach and privacy law
Manufacturers hold more personal data than they think: employee records, payroll and benefits files, and customer contacts. Connecticut's § 36a-701b requires notice to affected residents within 60 days of discovering a breach, plus notice to the Attorney General, and since July 1, 2026 the Connecticut Data Privacy Act applies to companies processing data on 35,000 or more consumers or any sensitive data.
Customer and export requirements
Medical-device customers expect records that support FDA quality system requirements, and companies handling export-controlled technical data under ITAR or the EAR must keep it from unauthorized foreign persons, which affects where files are stored and who can reach them. We configure storage and access to match the rules your counsel or quality team identifies. This is general information, not legal advice.

Manufacturers in Fairfield County: FAQs
Who provides IT support for manufacturers in Fairfield County?
NetSys does, from its single office in Park Slope, Brooklyn, as a managed IT and cybersecurity provider founded in 1998. We support manufacturers and suppliers across the county: on site in the lower county, remotely first with confirmed drive times in Bridgeport, Stratford, Trumbull and Danbury, and remotely in Shelton and the northern towns. One agreement covers the ERP infrastructure, shop-floor network, security, backups, Microsoft 365 and the calls to your vendors.
What does IT support cost for a manufacturer in Fairfield County?
Per user per month, set after an assessment; we do not publish a rate. The things that move it are the number of office users and shared shop-floor PCs, how many servers and plants are involved, whether you handle controlled unclassified information, the ERP's hosting and backup needs, and the condition of the network. Projects such as an ERP server replacement, a new building or segmenting the floor are quoted separately.
How do you help defense suppliers with NIST SP 800-171 and CMMC?
We start by drawing the boundary: which people, devices and storage touch controlled unclassified information. Inside it we implement and document the 110 requirements, from multifactor authentication and audit logging to media protection, and we help you score the self-assessment you post in SPRS. With CMMC Phase 2 suspended since July 2026, certification timing is uncertain, but DFARS 252.204-7012 obligations and the self-assessment are current, so the work is not wasted.
Do you support our ERP and machine software?
We support the servers, databases, PCs, network and access around them, and we work with your ERP and equipment vendors on application issues, opening tickets and scheduling updates with them. Versions, licenses and vendor contacts are documented in IT Glue so the next outage starts with facts. We do not claim certification on any particular ERP or CAM package, and we say when a problem belongs with the vendor.
Can you segment the shop floor without stopping production?
Yes, in stages and usually on a weekend or between shifts. We first map every device on the floor and what it talks to, then move machines onto their own network segment one cell at a time, with firewall rules that allow only the traffic they need. Each change has a rollback, and for plants in the lower county an engineer is on site for the cutover. For Bridgeport and Stratford plants we confirm drive time first.
