The five IT support challenges every UK manufacturer is wrestling with

In a professional services firm, an hour of email being slow is annoying. In a manufacturing plant, an hour of the line being down is a number. There is a quantity that didn't get made, a shift that didn't earn, and a customer order that just moved a day to the right. The whole conversation about IT support sits on top of that fact.

It changes what 'priority one' actually means. A ticket that says 'EPOS slow at till 3' or 'ERP can't post a goods receipt' is not the same as 'Outlook search isn't working'. The support team needs to understand which systems are line-touching and which aren't, and the SLAs need to reflect that. A flat four-hour response on everything is not a manufacturing SLA.

It also changes the economics of preventative work. Spending a day a quarter on patch hygiene, identity reviews and backup restores looks expensive on paper. Set it against a single avoided day of stopped production and it pays back many times over. The manufacturers who run this well treat it as insurance, not as IT housekeeping.

The estate on the floor doesn't behave like the estate in the office. PLCs, SCADA servers, HMIs and bespoke machine controllers were commissioned by the original equipment manufacturer, often years ago, and they were not designed to be patched the way laptops are. Many of them run operating systems that are out of mainstream support. Some of them cannot be rebooted without a planned production stop.

What that means in practice is that 'just put the agent on it' is not an answer. These systems need to be segmented from the corporate network, monitored passively rather than actively poked, and protected by what's around them rather than what's on them. The support partner has to be comfortable with that asymmetry and not panic into trying to standardise everything.

It also means the partner needs to be able to talk to the OEM. When a machine misbehaves and the OEM's remote support needs to come in, the IT team is the gatekeeper, not the obstacle. A jump host, a time-bound access window and a clean audit trail is the right answer; a permanent VPN tunnel from the OEM straight into the production network is not.

Almost every mid-market manufacturer has an ERP or MRP system that is a generation behind. Sometimes two. It schedules the work, holds the bill of materials, prices the quotes and runs the finance. Migrating it is a multi-year, multi-hundred-thousand-pound conversation. Leaving it where it is feels safer until something breaks.

The risk isn't the ERP itself, which usually plods along. It's the integrations. The overnight CSV that pushes orders into the dispatch system. The Excel macro on someone's desktop that reconciles stock counts. The print spooler that nobody has touched since 2018. When these break, the line doesn't stop instantly, but the data feeding the line goes wrong, and the line stops a day later.

Good IT support for a manufacturer takes these integrations seriously. They get documented, monitored where possible, and given an owner. A modernisation programme can then take its time without the business holding its breath every Sunday night.

Ransomware groups have done the maths on manufacturing. A factory standing idle for a week costs more than almost any ransom they would dare ask for, and most plants do not have the recovery muscle to refuse. The sector keeps showing up at the top of incident reports year after year, and insurers have noticed: premiums are up, exclusions are sharper, and the renewal questionnaire is now twenty pages long.

Almost no ransomware attack on a manufacturer starts on the shop floor. It starts in a mailbox. Someone in finance, operations or quality clicks a link, an attacker gets a foothold on a Windows laptop, and from there they move laterally. On a flat network there is nothing structural to stop them reaching file shares, the ERP server and, in the worst cases, control systems.

The defences that actually move the needle are unglamorous: multi-factor authentication everywhere, conditional access in Entra ID, immutable backups of Microsoft 365 and the file shares the planners use, network segmentation between office and floor, and a tested recovery plan. None of that is exotic. It is, however, often missing.

There are not many people who genuinely understand both Microsoft 365 and shop-floor systems. The Venn diagram of 'Intune-fluent' and 'has spent a day in a portacabin next to a CNC machine' is small. Outside the major cities it is smaller still. Recruiting an internal IT lead with that profile is hard and getting harder.

That is the strongest argument for an external partner who already has both. The economics of a small in-house team trying to cover Microsoft, networking, OT and cyber rarely work, and the burnout is real. A partner with a roster of similar manufacturers brings the pattern recognition with them.

When picking that partner, the question to ask is whether they show up speaking both languages on day one, or whether they need a translator. The good ones can walk the floor with the production manager in the morning and run a Microsoft 365 governance session with finance in the afternoon. The generic ones can only do the afternoon, and that is the half of the estate that wasn't going to break the business anyway.

If you recognise four out of the five, you are in the majority, not the minority. Manufacturers do not generally fix this with a single big project. They fix it by changing the support arrangement so the right things get attention every month: backups tested, identity reviewed, segmentation tightened a notch, integrations documented, recovery plan rehearsed.
