IT security for production and suppliers

In the Trnava Region a network problem rarely affects just one workstation but a line. That is why separating the machine network from the office network comes first here.

In short

Who handles IT security for production companies in the Trnava Region?

NDVDL plans and maintains IT security for production companies, suppliers and family businesses in the Trnava Region: firewall concept and setup, separating machine and office networks, controlled remote maintenance access for equipment vendors, monitoring and ongoing upkeep of the rules. In a region with many manufacturing and supplier operations the decisive question is rarely the antivirus product but the network structure: controls, operator panels and test benches must not sit on the same network as workstations and accounting. On top of that come requirements passed down from customers. First conversation free: +43 800 007075 or office@ndvdl.io.

What matters in manufacturing and supply

Separate machine and office networks

Machine controls often run on systems that can no longer be updated because the manufacturer ties their approval to a specific state. That is precisely why they belong in their own network segment with clearly defined transitions — not on the same network as email and accounting.

Remote maintenance by equipment vendors

Almost every larger machine brings a remote maintenance access with it, usually set up by the supplier and rarely documented. Such access belongs in an inventory, routed through a controlled path and limited in time — instead of standing as a permanently open door into the production network.

Requirements from the supply chain

Anyone supplying larger customers gets their security requirements passed down — from access control through logging to evidence in an audit. Those points can be implemented technically; what matters is settling them before the audit rather than after.

NIS2 as a framework, not a panic topic

The NIS2 directive affects more businesses than before, directly or as suppliers. What it asks for at its core is sensible anyway: know your risks, limit access, notice incidents and be able to report them. We implement the technical side; whether and how a business is covered legally is a matter for legal advice.

Technical questions about this project

The office network carries workstations, email and administration; the OT network runs the controls, operator panels and sensors of production. The two have different priorities: in the office confidentiality counts, in production it counts that the line keeps running. Because systems there often cannot be updated, separation is the most effective protection.

Usually not. The separation happens in the network — through dedicated segments, defined transitions and firewall rules — not in the machine itself. What matters is surveying beforehand which systems genuinely have to talk to each other, so the rules do not block operations.

That depends on sector, size and role in the supply chain and is a legal classification — one for legal advice, not for us. Regardless of that, the technical requirements can be implemented: network separation, access control, logging and a way to notice incidents in the first place.

A firewall at the internet boundary protects against access from outside. It says nothing about what is allowed to happen inside the network: without segmentation, an infected office PC reaches the control in the hall just as easily as the file server. The question is therefore not whether a firewall exists but which rules apply between the areas.
