Manufacturing IT Support in Detroit, MI
Metro Detroit manufacturers stamp, mold, machine and assemble for Ford, GM and Stellantis, and for the Army ground-vehicle programs managed from Warren. NetSys looks after the IT behind that work, remotely from Brooklyn: ERP servers and their backups, plant networks walled off from the office, ThreatDown on every computer, and the security paperwork OEM and defense buyers expect.
The short answer
NetSys provides IT support and cybersecurity for manufacturers across metro Detroit, from Tier 1 and Tier 2 auto suppliers in Auburn Hills, Troy and Sterling Heights to tool shops and defense subcontractors near the Detroit Arsenal. We manage office and plant-floor computers, the network and its segmentation, Microsoft 365, ThreatDown detection and response, backups that include ERP databases and CNC programs, and documentation for NIST SP 800-171 and customer audits. We work remotely and do not send engineers to plants; equipment arrives configured for your maintenance staff to install. Alerts are watched 24/7, engineers answer the help desk between 4 a.m. and 11 p.m. Eastern, and the per-user monthly price comes out of an assessment.

What changes for a manufacturer in Detroit
Manufacturing employed about 235,100 people in the Detroit-Warren-Dearborn metro in September 2026, according to preliminary Bureau of Labor Statistics figures, and much of that work traces back to three automakers. Ford is headquartered in Dearborn, GM in downtown Detroit and Stellantis runs its North American operations from Auburn Hills, while the 2025 Fortune 500 list adds suppliers Lear in Southfield and BorgWarner and Autoliv in Auburn Hills. Below them sits a long tail of stampers, molders, machine shops and tool-and-die makers across Wayne, Oakland and Macomb counties. Defense adds a second customer base: TACOM, headquartered at the Detroit Arsenal in Warren, manages the supply chain for about 60% of the Army's equipment, and Michigan counts about 4,000 defense suppliers. Those customers set the IT agenda. OEM purchase orders arrive with security questionnaires and EDI requirements, German automakers can ask for a TISAX label, and defense contracts carry DFARS 252.204-7012. The cost of getting it wrong is visible here too: one supplier's ransomware attack disrupted Stellantis assembly plants in November 2023.
How remote IT support works for a Detroit plant
Plant IT can be run from a distance when the preparation happens before the hardware ships. Line terminals, quality-lab PCs and engineering workstations are registered in Intune and Windows Autopilot with their station names and software, and switches, access points and firewalls are built from a saved configuration. NetSys does not send engineers to Detroit-area plants, so your maintenance technician or controls contractor mounts and cables the equipment while our engineer brings it online over the network and checks each port. Updates respect the production calendar: front-office computers patch weekly, and PCs attached to presses, robots or measuring machines wait for a changeover or a maintenance window you sign off on. Night shifts fall under round-the-clock monitoring, and engineers are at the help desk from 4 a.m. Eastern, which is also Detroit time.
The ERP, EDI releases and the network between office and floor
A Detroit supplier's day runs on data from its customers. OEM releases and advance ship notices travel by EDI, production schedules come out of the ERP, part programs reach CNC machines from a DNC share, and inspection results flow back into quality records a customer can audit. Downtime usually starts where two of those systems meet. We map the flows first, then segment the network so office users, engineering seats, machine-side PCs, cameras and vendor support connections each sit in their own zone, with the firewall allowing only the traffic the map shows. When a robot integrator or press builder needs remote access, we open a session for that job, require multifactor sign-in, record it and close it afterward. The ERP vendor or reseller stays responsible for the software itself, while we look after the server or cloud instance it runs on, its database backups, the client installs and the shipping-label printers that hold up trucks when they fail.
Ransomware, ice and keeping parts shipping
Two kinds of disruption matter most to a Detroit plant. The first is a cyberattack: the November 2023 attack on Yanfeng, an interiors supplier with its North American base in Novi, interrupted production at several Stellantis plants in North America, with full output restored by November 16, and Qilin, the group that claimed it, published what it said were quotation files and technical data sheets. The second is weather. The February 22, 2023 ice storm cut power to more than 600,000 DTE customers, and the storms of September 3, 2026, which included the first confirmed tornado inside Detroit since 1997, left about 242,000 customers still dark the following morning. A continuity plan for a plant covers both: immutable backups of the ERP database, CAD files and CNC programs kept outside the region, a written shutdown and restart order, UPS units sized to close the ERP cleanly, and cellular failover so EDI and shipping keep moving.
Customer drawings, prototypes and who can open them
Detroit manufacturers hold data that belongs to their customers: OEM part models, prototype details, tooling designs and, for defense work, controlled unclassified information. Each customer expects that data to stay with the people working on its program. We organize engineering files in SharePoint or a managed file server by customer and program, grant access by group rather than by individual, and require multifactor sign-in from managed devices through Conditional Access. Keeper holds the shared machine and vendor passwords that otherwise end up on sticky notes. USB storage is controlled through Intune, and Microsoft 365 data loss prevention policies can warn or block when a file labeled confidential is sent outside the company. For defense programs, the same structure becomes the system boundary that your NIST SP 800-171 security plan describes.

Rules that shape IT for Detroit manufacturers
Defense work: DFARS 7012, NIST SP 800-171 and CMMC's suspended Phase 2
Defense work in metro Detroit, much of it flowing from Army programs managed by TACOM in Warren, often involves controlled unclassified information. Where a contract includes DFARS 252.204-7012, the supplier must implement the controls in NIST SP 800-171 Revision 2, send cyber incident reports to the Department of War and maintain a current SPRS score with its affirmation. The certification side of CMMC is paused: on July 13, 2026 the department suspended Phase 2, which would have tied awards to third-party Level 2 certificates from November 10, 2026, and froze Phases 3 and 4 pending a reform task force review. Self-assessments at Levels 1 and 2 continue.
OEM security terms and TISAX
Automaker and Tier 1 customers set their own information security terms, and supplier security questionnaires arrive with sourcing packages. Suppliers to German automakers can be asked for a TISAX label. TISAX rests on the Information Security Assessment catalog that the VDA publishes and the ENX Association maintains; an accredited audit provider carries out the assessment, and results go only to partners the supplier chooses through the ENX portal. NetSys prepares the IT controls and evidence, and the assessment itself comes from the audit provider.
Michigan's Identity Theft Protection Act
Payroll and HR files give every plant a store of employee Social Security numbers, bank account details and driver's license numbers. Under MCL 445.72, a breach of that data requires notice to affected Michigan residents without unreasonable delay unless the business determines it is not likely to cause substantial loss, injury or identity theft, and notifying more than 1,000 residents also means telling the nationwide consumer reporting agencies. A knowing failure to notify can draw a civil fine of $250 for each failure, with $750,000 as the ceiling for a single breach. This is general information, not legal advice.
Windows and Windows Server end-of-support dates
Two dates drive plant computer decisions. Windows 10 support ended October 14, 2025, and Windows Server 2016's extended support runs out January 12, 2027. Any controller PC or plant server on either one needs a decision: replacement, Microsoft's paid extended security updates where they are offered, or isolation in a locked-down network segment when the machine builder will not certify a newer operating system. A customer auditor or cyber insurer may ask to see that inventory, so we keep it current and dated.

Manufacturers in Detroit: FAQs
Who provides IT support for manufacturers in Detroit?
Detroit manufacturers can choose among local integrators, regional managed service providers and remote firms. NetSys is in the last group: a managed IT and cybersecurity company founded in 1998, with one office in Brooklyn and no Michigan branch. Its engineers hold degrees in computer science and electrical or electronics engineering plus Cisco and Microsoft certifications, and a single month-to-month agreement covers office IT, plant-floor computers, security and vendor coordination, with an account manager you can reach on a real cell phone. If you want a technician physically walking your plant each week, a Michigan firm suits you better, and we would rather say so now.
What does IT support cost for a manufacturer in Detroit?
Managed IT for a manufacturer is priced per user per month after an assessment, with shared plant-floor terminals usually counted as devices rather than users, and no rate is published. What changes the number is how many plants and circuits you run, how many servers still run in your buildings, how much segmentation the plant network needs, and the compliance documentation your customers expect, such as NIST SP 800-171 or preparation for a TISAX assessment. Hardware, licenses and projects like an ERP server migration carry separate quotes, and the agreement renews monthly.
How do you help Detroit suppliers meet NIST SP 800-171 and CMMC requirements?
The first step is scoping: deciding which systems store or process controlled unclassified information. Those systems are then measured against the 110 requirements in NIST SP 800-171 Revision 2. The result is a system security plan, a plan of action for open items and an SPRS score you can stand behind. Then we close the gaps: Conditional Access and multifactor sign-in, ThreatDown on every endpoint, encrypted and access-controlled file storage, logging, Keeper for shared credentials and Rapid7 scanning. With CMMC Phase 2 suspended since July 13, 2026, the practical goal is an honest self-assessment now and a program ready for certification if it resumes.
Do you support our ERP and plant-floor software?
We support the infrastructure every manufacturing ERP depends on, whichever product you run: the server or cloud tenant, the SQL database and its backups, client installs, printers, scanners and the network out to the floor. The ERP vendor or reseller stays responsible for the application, and we handle the back-and-forth with them on your behalf. The same applies to MES, quality, CAD and PLM systems and the DNC software that sends programs to machines. Before any upgrade or server move, we confirm the vendor's requirements in writing and schedule the cutover around production.
Can you secure the network between our office and the plant floor?
Yes. We inventory everything on the plant network, including PCs attached to machines, PLC programming laptops, cameras, badge readers and vendor modems, then place them in segments separated from office users by a Fortinet or Meraki firewall. Only the traffic the plant needs crosses that boundary, such as the ERP sending work orders or a historian passing data upstream. Machine builders get recorded, time-limited remote sessions instead of always-on modems, and controller PCs still on Windows 10 are isolated rather than left beside email users. The design is documented so a customer auditor can follow it.
Can you support a plant in Windsor alongside our Detroit operations?
Yes. Remote support reaches a plant in Windsor the same way it reaches one in Sterling Heights, and Ontario keeps Eastern time, so the help desk hours line up exactly. The same engineers, firewall standards and device policies cover every site under one agreement, joined by encrypted tunnels between the firewalls. What changes at the border is practical: carriers and hardware suppliers differ, shipments can wait at customs, and records about Canadian staff raise Canadian privacy questions, so we document where each system and record lives for your counsel. The Gordie Howe International Bridge, open since July 27, 2026, has added a second major crossing for parts and people.
