Your equipment doesn’t know what year the OS shipped. Neither should your IT.
Downtime on a plant floor isn't a slow ticket queue — it's a stopped line, a missed shipment window, and a customer contract with a penalty clause. Most MSPs handle that risk by refusing to touch anything older than five years. We segment it, secure it, and keep it running.

In an office, an IT outage means someone can’t check email for an hour. On a production floor, the same outage stops a physical line — labor keeps running, materials keep aging, and a shipment window can close before anyone reopens a ticket. If that delay cascades into a customer contract with a penalty clause, the IT problem just became a line item on next quarter’s P&L. That asymmetry is why we treat production-floor changes differently than office changes: a patch that’s routine on a laptop can be a production incident on a controller.
The other cost is the one nobody puts in the incident report: the equipment itself. A CNC controller, a PLC, or a SCADA workstation is often a six- or seven-figure capital investment that still has a decade of useful life left — running on an operating system the vendor stopped patching years ago. The generic answer is “replace it.” The real answer is usually “isolate and secure it,” because replacing a working machine to satisfy an IT policy is rarely the economically sane move.
Why legacy Windows and SCADA end up running production
This isn’t neglect — it’s how industrial equipment gets bought. Vendor software gets certified against a specific OS version at purchase time and often never gets re-certified. Ten years later, the machine still works, the vendor either doesn’t exist anymore or wants a six-figure quote to requalify on new hardware, and the plant is left running Windows 98, XP, or 7 on a box that controls something expensive. We see this constantly, and it’s exactly the kind of infrastructure our automated configuration backup work is built to protect — production systems where “just reinstall it” isn’t an option if something breaks.
The compliance regime: segmentation, not replacement
OT/ICS security standards don’t require every legacy machine to disappear — they require the production network to be segmented from the office network, so a phishing click in accounting can’t reach the machine running your press. That segmentation, plus dedicated firewalls and monitoring scoped to the OT segment, is the baseline control most auditors and cyber-insurance underwriters actually check for. If your firm also touches customer financial or health data on the office side, FTC Safeguards or HIPAA can apply there too — we map the frameworks that actually govern your environment before naming one.
How we patch a fleet without stopping the line
Office IT gets patched whenever; production IT gets patched on a schedule the plant sets. We push fleet-wide updates the same way we handle it everywhere else — verified, staged, and scheduled after hours, the same discipline behind our mass BIOS and driver patching work and our patch-compliance reboot automation. When a maintenance window only exists at 2am on a Saturday, we use Wake-on-LAN scheduling to make sure machines are actually awake to receive it — instead of finding out Monday morning that half the fleet slept through patch night.
And when a machine on the floor locks someone out mid-shift, we don’t make you wait for a truck roll. Our emergency local admin process via RMM gets a technician back into a locked machine remotely, in minutes, without exposing standing admin credentials on the plant floor.
What Limehawk builds for a manufacturing environment
- Network segmentation — production and office traffic separated, so a compromise on one side can’t reach the other.
- Dedicated firewalls and OT monitoring — scoped to the segment that actually needs watching.
- Legacy system support — Windows 98 through 7, SCADA, and unsupported vendor software kept patched where possible and isolated where it can’t be.
- Production-aware change management — patches and maintenance scheduled around your shifts, not pushed blind.
- Migration planning — a real timeline for vendor-driven upgrades, on your capital schedule, not a forced rip-and-replace.
This runs on top of our standard managed IT and security baseline — $150 per user per month, 24/7 monitoring, endpoint detection and response, and patch management included, with a <15 minute response commitment on anything critical. Month-to-month, no multi-year contract, published pricing.

Manufacturing IT, plainly explained
Pricing included — because “call for pricing” is how IT companies hide the number.
See full pricing →What does downtime actually cost a manufacturer?
It's not just idle labor — it's a stopped line, missed shipment windows, and penalty clauses in customer contracts if the delay cascades. A generic MSP that pushes an update mid-shift, or that quarantines a machine because its OS is unsupported, can cost you a production run over an IT decision that had nothing to do with the equipment itself.
Can you actually support Windows 98, XP, or 7 machines controlling production equipment?
Yes. We don't tell you to replace a controller that runs fine because its OS is old. We isolate it on its own segmented network, put monitoring and a dedicated firewall around it, and document the compensating controls so it's defensible in an audit — while planning the eventual vendor-driven migration on your timeline, not ours.
Do you touch equipment during production runs?
No. Patching, updates, and maintenance windows get scheduled around your production schedule, not the other way around. We've worked plant floors and we plan changes the way our fleet-wide patching and reboot automation is built: after-hours, verified, and rolled back fast if anything looks wrong.
What compliance framework applies to manufacturing IT?
It depends on what you make and who you sell to, but OT/ICS security standards call for network segmentation between production and office systems as the baseline control — separating the systems that run machines from the systems that run email and finance. If you also handle customer financial or health data, FTC Safeguards or HIPAA can layer on top. We map your actual environment before naming a framework.
Our internal IT is stretched between the office and the plant floor. Can you help without replacing them?
Yes — this is a common setup for us. We co-manage: your internal team keeps ownership of what they know best, and we take the after-hours coverage, the OT segmentation work, and the specialized legacy-system knowledge that's hard to hire for in-house.
What does this cost?
Base managed IT and security is $150 per user per month, minimum 3 users, month-to-month with no contract — 24/7 monitoring, endpoint detection and response, and patch management included. Network segmentation, dedicated firewalls, and legacy-system support are scoped to your floor plan. Full pricing is published at /pricing.
