Managed IT & OT Security for Manufacturers

When a line goes down, the clock is money. LRG keeps your IT and your shop-floor systems running, segmented, and secure — protecting uptime as the first priority and watching the boundary between the office and the floor. One partner, one number, for both.

[ 01 — The pressure ]

Downtime isn't an inconvenience — it's revenue walking out the door.

You already know the math: when a line stops, you lose the repair time, every unit that line would have produced, the labor standing around waiting, and the order you now ship late. And the threats to uptime aren't just mechanical. A ransomware hit that locks up your office network can idle the floor as fast as a broken machine — especially when the systems that run your equipment share a network with email and accounting. Most IT providers treat a manufacturer like an office that happens to have a warehouse.

[ 02 — Where it breaks ]

Risks an office-only IT company misses.

A flat, exposed network

01

When control systems, office PCs, and guest WiFi all share one network, a phishing email on a laptop can reach the machines that run production — the exact path to a line-stopping ransomware event.

Downtime measured in production

02

Without proactive monitoring, patching, and tested backups, an hour of downtime is lost output, not just a help ticket — and recovery is slow when nobody planned for it.

Requirements you can't answer

03

Insurers and larger customers now demand MFA, EDR, tested backups, and access control before they'll write a policy or keep you in the supply chain — and you have to prove it.

[ 03 — How we help ]

Two different worlds, connected carefully.

A single flat network turns every threat into a plant-wide threat. We put the shop floor on its own protected zone, tightly control what passes between it and the IT side, and monitor the boundary — so systems can talk when they need to and stay walled off when they shouldn't. Uptime and security are the same conversation for a manufacturer, and we run both.

01
Uptime first
Proactive monitoring, patching, tested backups, and fast recovery — because an hour of downtime is measured in lost production, not just a help ticket.
02
IT/OT segmentation
We separate the network that runs your machines from the one that runs email and accounting, control what passes between them, and watch that boundary so a breach can't cascade.
03
Insurance & supply-chain ready
We deploy the controls your carrier and customers require — MFA, endpoint protection, backup, access control — and document them so you can answer the questionnaire honestly.
[ FAQ ]

Manufacturing IT questions, answered.

Why should manufacturers separate the shop floor from the office network?+

Because a single flat network turns every threat into a plant-wide threat. When control systems, office PCs, and guest WiFi share one network, a phishing email on an office laptop can reach the machines that run production. Segmentation puts the shop floor on its own protected zone, controls what passes between it and the IT side, and contains a breach instead of letting it spread.

Can a cyberattack actually stop my production line?+

Yes — and it's one of the most common ways manufacturers get hurt. Ransomware that encrypts your office systems can idle the floor if production depends on them, and on a flat network the malware can reach control systems directly. The defenses are the same fundamentals good IT security provides: tested backups, endpoint protection, MFA, and segmentation.

Does this help us meet cyber-insurance requirements?+

It directly supports them. Carriers now require MFA, endpoint detection, tested backups, and access control before they'll write or renew a policy — and your larger customers are starting to require the same in their supply chain. We put those controls in place and document them so you can answer the questionnaire honestly.

We supply parts to defense primes — do we need CMMC?+

If you handle Controlled Unclassified Information anywhere in your DoD supply chain, you're likely on a path to CMMC, and many manufacturers are. The cyber-insurance and segmentation work above overlaps heavily with what CMMC requires. We cover that path in depth on our defense contractors page.
