Security Solutions for Manufacturing Companies
By CtrlOne Team ·
Manufacturing has quietly become one of the most attacked industries. The reason is simple: downtime is expensive, so manufacturers are under pressure to pay when production stops. At the same time, shop-floor computers are some of the hardest endpoints to secure - they run old software tied to specific machines, they are shared between shifts, and taking them offline for maintenance means stopping the line. Security for manufacturers has to protect these devices without getting in the way of production.
Why manufacturers are increasingly targeted
A stopped production line costs money every minute, which makes manufacturers more likely to pay a ransom to get running again. Many also hold valuable intellectual property - designs, formulas, and processes. And the mix of old and new equipment on a typical shop floor leaves plenty of gaps for an attacker to use.
What makes shop-floor endpoints hard to secure
The obstacles are practical, not theoretical:
- PCs tied to specific machines running old, unpatched software.
- Terminals shared across shifts and left logged in for continuity.
- USB drives used to move files to and from equipment - a major malware path.
- Downtime for updates is costly, so patching is delayed or skipped.
- Flat networks where one infected machine can reach the whole plant.
A security approach that fits the factory
Because you often cannot upgrade or reboot shop-floor systems freely, the most effective protection is to lock down what each machine is allowed to do:
- Application control so only the software needed to run the line executes.
- USB control that blocks unauthorized removable storage while allowing approved devices.
- Locking down Control Panel, Settings, and command-line tools on operator profiles.
- Restricting web access on machines that only need line-of-business apps.
- Enforcing the same baseline on every terminal and verifying it centrally.
Protecting production without stopping it
The key requirement in manufacturing is that security cannot cause downtime. Policy-based restrictions applied at the endpoint do not require rebooting equipment or changing the applications the line depends on - they simply limit what can run and what can be plugged in. Enforcement has to be tamper-resistant so operators cannot switch it off to get a task done, and it has to keep working even on machines that are isolated from the corporate network.
Manufacturing endpoint security with CtrlOne
CtrlOne applies application, USB, web, and system restrictions as managed policies across shop-floor and office PCs from one console. Enforcement does not depend on the network and cannot be casually disabled, so operator terminals stay locked to their job without downtime - and IT can manage the whole plant without walking the floor machine by machine.
Frequently asked questions
Why is manufacturing a growing target for cyberattacks?
Downtime is extremely expensive, which makes manufacturers more likely to pay to restore production, and shop floors mix old and new equipment that leaves security gaps. Many manufacturers also hold valuable intellectual property.
How do you secure shop-floor PCs that cannot be patched?
Lock down what each machine can do with policy-based restrictions - application control, USB control, and disabling system tools - so an unpatched terminal is still constrained to its job and cannot run untrusted code.
Can endpoint security be applied without production downtime?
Yes. Policy-based restrictions limit what can run and connect without rebooting equipment or changing line-of-business software, so they can be applied without stopping the line.
