Cybersecurity & IT Services for UK Manufacturing

Manufacturers carry a risk profile no other sector quite matches: legacy machinery that cannot be patched on demand, production systems now wired to ERP and the internet, and customers who increasingly demand proof of security before they place an order. Our managed IT support for manufacturing is built around that reality — protection that respects the maintenance window.

What does managed IT support for manufacturing cover?

It covers the whole estate: office workstations and servers, cloud and ERP platforms, and the operational technology on the production floor. The goal is one accountable provider keeping IT secure, available and supported — without the changes that risk halting a line.

• OT/IT network segmentation — production systems on a separate, firewalled segment so an office infection cannot reach machine controllers.
• Production system backup and recovery — immutable, offsite backups of ERP, production configuration and business data, with tested restores.
• 24/7 threat monitoring — continuous watch over network and endpoint activity, tuned for manufacturing, via Microsoft Defender for Endpoint monitored by AMVIA's in-house SOC.
• Cyber Essentials for supply chain — certification support to meet customer and prime-contractor requirements.
• ERP and Microsoft 365 security — MFA, Conditional Access and data-loss prevention protecting commercially sensitive production data.
• Resilient connectivity — dedicated leased lines for factories that depend on reliable, high-throughput links to cloud and remote sites.

Why is manufacturing the most targeted UK sector for ransomware?

Attackers chase leverage, and few targets feel pressure faster than a manufacturer with a stopped line. Production downtime converts directly into lost revenue and broken delivery commitments, so the temptation to pay a ransom is acute. Manufacturing is now the most targeted UK sector for ransomware.

The picture is stark: every hour of stopped production carries a heavy cost, and 19,000 UK businesses were hit by ransomware in 2025 (Sophos). The wider picture is documented in the government's Cyber Security Breaches Survey, which tracks attack rates across UK businesses each year. Three factors make manufacturers stand out: legacy systems with limited patching, complex supply-chain connections that create entry points, and valuable intellectual property.

How does OT/IT convergence change manufacturing security?

OT/IT convergence is the merging of operational technology (PLCs, SCADA, industrial control systems) with corporate IT networks. Traditional factory security treated OT as isolated; that separation no longer holds when production systems connect to ERP platforms, supplier portals and remote monitoring. The result is an attack surface neither standard IT tools nor legacy OT tools fully cover.

The practical risk is lateral movement — ransomware landing on an office laptop, then reaching the controllers that run the line. The NCSC's guidance on operational technology makes network segmentation the primary control: keep OT and IT on separate segments, monitor and restrict the traffic between them, and treat any path into the production network as privileged. AMVIA assesses the full environment — from office workstations to floor controllers — prioritising availability alongside protection.

How do you secure production systems without disrupting operations?

Carefully, and passively. Securing OT means visibility and containment first: passive network monitoring rather than active scans of sensitive ICS devices, vulnerability assessment that does not probe fragile controllers, and change-controlled patching aligned to maintenance windows. AMVIA works around production schedules, not against them.

The sequence we follow is segmentation and monitoring before any change that could affect uptime. Remote access to production gear runs through MFA-protected, dedicated access — never a general-purpose VPN. This is where security and managed cybersecurity meet operations: the controls have to protect the plant without ever being the reason it stops.

In-house IT vs managed IT for manufacturers

A single in-house technician rarely covers OT security, 24/7 monitoring and ERP hardening at once. Managed IT spreads that load across a certified team with round-the-clock cover — the difference between best-effort and accountable.

Manufacturing cybersecurity checklist

These are the controls we check first on a manufacturing site, aligned to NCSC operational-technology guidance and common supply-chain requirements.

• OT and IT networks segmented — production systems on a separate, firewalled segment; OT/IT traffic monitored and controlled.
• Remote OT access secured — any remote access to production via MFA-protected, dedicated solutions, not a general VPN.
• Asset inventory complete — every IP-connected device, including OT/ICS equipment, in an asset register. Undiscovered devices are unprotected devices.
• ERP and business backups tested — regular restore testing for ERP, production databases and configuration; recovery time objectives validated.
• Supply-chain requirements met — Cyber Essentials or CE+ in place where customers, primes or frameworks require it.
• Patch management applied — office IT patched within 14 days; OT patching assessed for compatibility and scheduled to maintenance windows.

How much does managed IT support for manufacturing cost?

Cost depends on staff numbers, the size of the OT estate, and whether you need full management or co-management of an existing team. Most manufacturers price it per user per month, with OT monitoring and connectivity scoped separately after a site assessment.

A single day of unplanned outage after a cyber attack can exceed the annual cost of managed security, which is why manufacturers tend to weigh the spend against downtime risk rather than headcount alone. We scope pricing against your actual environment — no generic per-seat quote before we have seen the floor.
