IT Services for Manufacturers in San Antonio

Why manufacturing IT is different from office IT

A manufacturer in San Antonio runs two environments that have to work together. The office side handles purchasing, scheduling, quoting, inventory, shipping, accounting, and email. The production side runs CNC machines, presses, molding equipment, packaging lines, and the PLCs and HMIs that control them. When the network between those two sides is unplanned, one hour of downtime is not an inconvenience. Work orders stop, shipping paperwork stalls, scanners drop off the network, and a just-in-time delivery window is missed.

The problems we see most often are not exotic. Wireless coverage that dies behind metal racking. Barcode scanners and label printers that disconnect every afternoon. Shared shipping workstations set up three different ways. An ERP vendor asking for network details nobody has written down. Office computers and machine controllers sitting on the same flat network, where one bad click in the front office can reach the floor. A practical support plan fixes those root causes and keeps them fixed.

Segmenting the office network from the plant floor

This is the first thing we look at in any San Antonio plant. Office workstations that browse the web and open email should never share a network with production equipment. We design and manage the boundary between the two: a firewall between the office and production networks, separate VLANs for office, production, cameras, and guests, and switching that keeps office traffic off the machine network entirely. If a phishing email lands on a receptionist’s PC, it stays on the office side and the line keeps running.

Your controls integrator or machine vendor keeps ownership of the PLCs, HMIs, and SCADA software. We handle the network around them: isolation, monitoring, documented rules for what is allowed to cross the boundary, and controlled remote access when a vendor needs to reach a machine. The approach follows the zones and conduits model described in ISA/IEC 62443, applied at a scale that makes sense for a small or mid-sized plant rather than a refinery.

If your machines run completely offline today, that is fine. We document that, keep it that way on purpose, and plan the boundary for the day a vendor wants telemetry from a line.

Cabling and wireless that survive a plant floor

Most IT companies start at the switch. We start at the wall. ASAP is a structured cabling and fiber contractor as well as a managed IT provider, and our network designs are led by an RCDD. On a manufacturing floor that matters. Stamping presses, welders, variable-frequency drives, and large motors produce electrical interference that degrades ordinary data cable. Metal shelving, steel structures, and moving forklifts create wireless dead zones that no amount of access-point shuffling fixes.

We plan pathways away from interference sources, run shielded copper or fiber where the environment calls for it, and place wireless access points based on a site survey rather than a guess, so handheld scanners and rugged tablets stay connected from the dock to the back of the warehouse. When a layout changes, we handle the moves, adds, and changes. See our structured cabling and fiber optic installation pages for the infrastructure side of the work.

ERP, MRP, EDI, and the software your plant depends on

Manufacturers in San Antonio run on specialized platforms: ERP and MRP systems such as Epicor, Plex, Global Shop Solutions, SAP, NetSuite, Fishbowl, or IQMS, plus CAD/CAM seats like SolidWorks and AutoCAD with license servers of their own, EDI connections to customers, and shipping and labeling systems tied to the dock. We support the servers, workstations, and network these platforms run on, and we act as the technical point of contact when the vendor needs someone to work a database link, a license server, or a connectivity problem.

Two things protect that software from taking the plant down with it. First, connectivity redundancy: a second internet circuit with automatic failover, so EDI, shipping, and cloud ERP keep working when the primary line drops. Second, change control: operating system patches and application updates are scheduled around production, tested where a workflow is validated, and documented, so an update never surprises the floor on a Monday morning. Our network support and Microsoft 365 management services cover the rest of the office stack.

Compliance and audit support, where it applies

Most San Antonio manufacturers we talk to are not preparing for an audit. They want uptime, working backups, and a help desk that answers. But many of them sell to customers who do audit, and the IT environment is part of what gets checked. Where a framework applies to your plant, we provide the IT controls behind it and the documentation to prove they exist. ASAP is your IT provider, not a certification body or a compliance consultant, and we keep that line clear.

• FDA 21 CFR Part 11 for electronic records and signatures: named user accounts, multifactor authentication, tamper-resistant audit logging, controlled access to record systems, and retention of security logs. Validation of the application itself stays with your vendor and quality team.
• SQF, BRCGS, and other GFSI audits: auditors ask for a documented disaster recovery plan, evidence that backups run and restore, and access controls on batch and traceability records. We maintain that documentation as part of the plan.
• FSMA traceability: keeping the ERP or inventory system that holds your traceability data available, backed up, and exportable when a request comes in.
• ISO 13485 and FDA 21 CFR Part 820 for medical device makers: change control on validated systems, documented and tested updates, and access controls on design and quality records.
• Automotive supplier requirements such as TISAX: network boundaries around customer CAD and tooling data, controlled access, and the security documentation your customer’s assessment asks for. We support the controls; the assessment is yours.
• Cyber insurance questionnaires: MFA, endpoint protection, backups, logging, and segmentation are the questions every carrier asks. We make the honest answer yes.

For every client, our own practices are the same: each customer runs in an isolated environment on our equipment, technicians use named accounts with MFA, security logs are retained for 12 months, and incident notification is written into the agreement. Details are on our computer security page and in our FAQ.

Manufacturers we support in San Antonio

Machine shops and metal fabrication. CNC machines on their own network segment for program transfer, CAD/CAM license servers that stay up, shop terminals that survive coolant and dust, and ISO 9001 documentation support. When Burke and Company, a San Antonio sheet metal and powder coating manufacturer, moved into a new building, we built the network, servers, and Wi-Fi and had the plant at full operating capacity in three days. Read the Clutch-verified case study.

Food and beverage processing. Canneries, bakeries, meat and tortilla processors, breweries, and packaging makers: office-to-line segmentation, batch and traceability systems kept available, and the backup and recovery documentation SQF and BRCGS auditors want to see.

Automotive parts suppliers. Just-in-time shipping means EDI and dock systems cannot go down. We provide failover connectivity, protected engineering data, and the response times a supplier contract expects.

Plastics and injection molding. Networked molding machines isolated from the office, shared floor stations standardized, and the quality-system controls medical or automotive customers pass down.

Medical device manufacturers. Change control on validated systems, Part 11 audit trails, and a Business Associate Agreement when a device or its data touches patient information.

Cabinetry, millwork, signage, printing, and building materials. CNC routers, large-format printers, design workstations, big files, and multi-yard connectivity, with an office of five to fifty people that has never had real IT.

Scope: we support commercial manufacturers across San Antonio, Central Texas, South Texas, and the Hill Country. We do not take on defense or government contract work, so if your contracts require CMMC, we are not the right fit and will tell you so up front.

Common issues we fix for manufacturing teams

• Wireless that drops scanners and tablets behind racking or at the far end of the warehouse
• Office PCs and machine controllers on one flat network with nothing between them
• Label printers and shipping stations that fail at the busiest hour of the day
• ERP slowdowns or lost database connections nobody can pin on the vendor or the network
• A single internet circuit with no failover for EDI and cloud systems
• Shared floor logins and accounts still active after staffing changes
• Backups that run but have never been restored
• Vendor escalations that stall because no one owns the technical answer
• Remote access for supervisors and vendors that is either blocked or wide open

Most of these come down to fundamentals done consistently: stable switching, proper cabling, a surveyed wireless layout, a real boundary between office and floor, clean device setup, and a repeatable plan for updates and backups.

Plans sized for a 10-person shop or a 100-person plant

Our managed IT plans cover San Antonio manufacturers from about 10 users to around 100, on an annual agreement. Pricing is per user, with $85 per user per month as a typical figure: roughly $1,700 per month at 20 users and near $8,500 at 100, adjusted for what you already have in house and what you add. If you have an internal point person, our co-managed IT option lets them keep day-to-day tasks while we take the network, security, and planning. Full pricing detail is on our managed IT services cost page.

For plant expansions, new buildings, or a move, our turnkey office IT build-out and IT relocation services handle the cabling, network, and cutover.

How an engagement typically starts

1. Initial intake to confirm users, locations, production systems, and what interrupts operations most.
2. Health review covering the office and production networks, cabling and wireless, workstation patterns, access setup, and backup readiness.
3. Service plan with priorities, practical recommendations, and options for ongoing management or a one-time project.

If you already have someone handling small tasks, we work alongside them and take ownership of the higher-impact reliability and planning items. If you do not, we provide a support process so staff know who to call and leadership can see what is improving.

Proof from a San Antonio manufacturer

Burke and Company, a sheet metal and powder coating manufacturer in San Antonio, had been an ASAP client for six years when they moved into a new building. They needed the internal network, servers, Wi-Fi, and workstation software in place fast enough to reach full production within a month. We finished in three days. In the Clutch-verified review, their VP of Operations rated the work 5.0 on quality, schedule, cost, and willingness to refer, and summed it up as “They were responsive and organized.” Read the case study (PDF).
