Manufacturing IT Support in Houston, TX
Houston manufacturers cut, weld and machine for the energy business, run chemical plants along the Ship Channel and build equipment shipped around the world. NetSys supports their IT remotely from Brooklyn: the ERP and the network it depends on, segmentation between the office and the plant floor, managed detection on every endpoint, and the controls defense and energy customers ask for.
The short answer
NetSys provides IT support and cybersecurity for manufacturers and industrial companies in Houston, from fabrication and machine shops to chemical and equipment plants along the Ship Channel. We manage office and shop-floor computers, the network and the segmentation between business IT and plant systems, Microsoft 365, ThreatDown managed detection and response, backups of the ERP and CNC programs, and NIST SP 800-171 documentation for defense work. Support is remote and cloud-based: hardware leaves Brooklyn configured, and NetSys does not send engineers on site. Monitoring runs 24/7, and the help desk is staffed 3 a.m. to 10 p.m. Central. Each user is billed monthly at a rate set after an assessment.

What changes for a manufacturer in Houston
Houston Facts 2025 counts 238,271 manufacturing employees in 7,209 establishments, about one in 14 workers in the region. Primary and fabricated metal products are the largest group at 56,544 workers, followed by chemicals, petroleum and coal at 51,003 and machinery at 39,861, a mix that mirrors the energy supply chain: pressure vessels, valves, pipe, compressors and oilfield tools. The region holds 694 chemical plants and 41 percent of U.S. base petrochemical capacity, plus refineries able to process 2.8 million barrels a day. Newer arrivals bring different demands, from Daikin's 500-acre Texas Technology Park in Waller to the 250,000-square-foot AI server plant Apple announced for Houston in 2025. Customers in energy, aerospace and defense attach security requirements to purchase orders, and a shop that machines parts for a defense prime may hold controlled unclassified information in its drawings. Weather sets the rest: Houston plants have worked through Harvey's flooding in 2017, the February 2021 freeze and Beryl's outages in 2024, which lasted more than a week for some customers.
How remote IT support works for a Houston plant
NetSys supports Houston manufacturers through remote and cloud tools only; we do not send engineers on site to plants or shops. Shop-floor PCs, engineering workstations and office laptops are built, enrolled in Intune and shipped labeled for their stations, and your maintenance electrician, controls integrator or cabling contractor handles mounting, cabling and anything inside a machine cabinet. Firewalls and industrial-grade switches arrive configured, and our engineer brings them up while your person on the floor plugs them in. NinjaOne patches office machines weekly and plant-floor PCs only in maintenance windows you approve, because a reboot in the middle of a CNC program or a batch costs real money. Monitoring and emergency service run 24/7 for second and third shifts, and the help desk is staffed 3 a.m. to 10 p.m. Central, seven days a week.
The ERP, the shop floor and the network between them
A Houston manufacturer's systems usually include an ERP with MRP, purchasing and quality modules, CAD and CAM software, a DNC system or file share that feeds programs to CNC machines, and sometimes an MES or historian on the plant side. Problems come from the connections. We divide the network into zones for business IT, engineering, plant-floor machines and controllers, and vendor access, with Fortinet or Meraki firewall rules allowing only the traffic each zone needs. Machine builders and integrators who need remote access get a monitored, time-limited connection with multifactor sign-in instead of a permanent remote-control tool on an HMI. Machine PCs still on Windows 10, which lost support on October 14, 2025, or on older versions are isolated rather than left on the office network. The ERP itself stays with its vendor or reseller; we keep the server, database backups, client installs and label printers working.
What the Colonial Pipeline attack and Gulf storms teach
Colonial Pipeline, whose system starts in Houston, shut down its fuel pipeline in May 2021 after ransomware hit its business IT network. The systems that move fuel were not directly compromised, but the company stopped them as a precaution, and its chief executive later told Congress the attackers entered through a legacy VPN account without multifactor authentication. For a manufacturer the lesson is direct: if office IT and the plant share a network or accounts, a breach in one stops the other. We require multifactor sign-in on every remote path, keep plant and office credentials separate, and run ThreatDown managed detection on every compatible endpoint. For weather, ERP data and CNC programs are backed up to immutable storage outside the Gulf Coast, servers run in Azure or a data center where practical, and the shutdown and restart order for plant systems is written down before hurricane season.

Rules that shape IT for Houston manufacturers
DFARS 252.204-7012, NIST SP 800-171 and the CMMC suspension
Defense suppliers handling controlled unclassified information must implement NIST SP 800-171 Revision 2, report cyber incidents to DoD within 72 hours under DFARS 252.204-7012, and keep a current SPRS score and affirmation. The Department of War suspended CMMC Phase 2 on July 13, 2026; that phase was to make third-party Level 2 certification a condition of award from November 10, 2026. Self-assessments at Level 1 and Level 2 continue while a reform task force reviews the program.
CFATS lapse and CISA's voluntary ChemLock program
Congress let the statutory authority for the Chemical Facility Anti-Terrorism Standards lapse on July 28, 2023, and CISA says it cannot enforce the CFATS regulations or require facilities to implement their site security plans, which included cyber measures. CISA encourages facilities holding chemicals of interest to keep their security measures in place and offers voluntary ChemLock resources.
Windows lifecycle dates
Windows 10 reached end of support on October 14, 2025, and Windows Server 2016 extended support ends January 12, 2027. Machine PCs and servers on either need replacement, a paid extended security update plan where one is available, or isolation on their own network segment, and the choice should be documented for auditors and insurers.
Texas breach law for employee and customer data
Business and Commerce Code 521.052 requires reasonable procedures to protect sensitive personal information, such as employee Social Security numbers and bank details, and 521.053 requires notice to affected individuals within 60 days and a report to the Attorney General within 30 days when 250 or more Texans are affected.

Manufacturers in Houston: FAQs
What does IT support cost for a manufacturer in Houston?
The fee is per user per month and comes from an assessment, never a published price list. For manufacturers it moves with the number of office and shop-floor computers, how many plants and circuits we support, whether the ERP runs on your servers or is hosted, how much network segmentation and vendor remote access we manage, whether NIST SP 800-171 documentation is in scope, and whether an internal IT or controls person keeps part of the work. ERP migrations and network redesigns are quoted separately. Agreements run month to month.
How does IT support work for Houston manufacturers?
Everything is remote. Supervisors and office staff reach engineers by phone, email or ticket from 3 a.m. to 10 p.m. Central, and monitoring and emergency service cover second and third shifts. Equipment ships configured and labeled, and your electrician, integrator or cabling contractor installs it while our engineer brings it online. We do not travel to Houston plants. A down ERP, a plant network outage or a suspected compromise goes straight to your dedicated engineer, and critical issues get a phone response within ten minutes and a remote response within thirty.
Where does CMMC stand for Houston defense suppliers in late 2026?
CMMC Phase 2, which would have required third-party Level 2 certification as a condition of award from November 10, 2026, was suspended on July 13, 2026, and a reform task force is reviewing the program; its report has not been made public as of late October 2026. What still applies: DFARS 252.204-7012, NIST SP 800-171 Revision 2, Level 1 and Level 2 self-assessments, and a current SPRS score and affirmation. We keep building to 800-171, because the controls and the contract clause have not changed.
Do you manage plant-floor and OT systems?
We manage the IT parts of the plant: Windows PCs on the floor, the network switches and firewalls, segmentation between zones, vendor remote access and backups of programs and configurations. PLCs, drives, safety systems and controller logic stay with your controls engineer or integrator, and we coordinate with them on network changes and maintenance windows. That boundary is written into the agreement, so nobody assumes the other side is patching a machine PC or watching the remote-access gateway.
Do you support our ERP?
We support everything the ERP depends on: the server or hosted connection, database backups and test restores, client installs on every workstation, printers and label printers, barcode scanners, and the network and identity behind them. Configuration, customization and problems inside the application belong to the ERP vendor or reseller; we open those tickets, supply logs and follow them through. When you are replacing an ERP, we plan the infrastructure side of the migration and the cutover with the new vendor.
How do you prepare a plant's IT for hurricane season?
Each spring we review the plan with you: confirm ERP and CNC program backups restore from outside the Gulf Coast, test the cellular failover on each firewall, check battery runtime for the network closet and servers, and update the written shutdown and restart order for plant systems with your controls engineer. When a storm is forecast, we verify the latest backups and shut down on-premises servers cleanly before landfall. Afterward, systems come back in the agreed order, and any damaged equipment is replaced with hardware we ship configured.
