IT-side vulnerability visibility for OT-adjacent and supply-chain-exposed environments.
What you are measured against
Manufacturers increasingly fall under NIS2 as important or essential entities, and many align their OT security programme to IEC 62443. The IT side of the plant, the engineering workstations, historians, and management servers that sit next to the control network, is where most vulnerability management actually happens. Customers and insurers also push supply-chain security requirements down the chain, so demonstrable control over IT exposure has become a commercial as well as a regulatory expectation.
Where the exposure sits
The dangerous zone in manufacturing is OT-adjacent IT: Windows machines that talk to control systems but run standard software with known CVEs. These are often poorly patched because they sit close to production and downtime is expensive. Supply-chain components and remote-access tooling for vendors widen exposure. A vulnerability on an engineering workstation can become a bridge from IT into the OT environment, which is why IT-side hygiene is a safety issue, not just a compliance one.
Turning regulatory pressure into evidence
Secuno covers the IT side of the plant: engineering workstations, historians, and management servers. Its agent inventories installed software and correlates it against known CVEs continuously, so an unpatched OT-adjacent machine is visible rather than forgotten. Configuration rules detect disabled firewalls, missing EDR, and unexpected listening ports, the conditions that let IT become a bridge into OT. Software inventory across every device gives the supply-chain visibility that customers and insurers ask for. Controls are scored against NIS2 and ISO 27001:2022, the same IT-side evidence supports your IEC 62443 programme, and patch verification re-checks after every inventory so a risk reopens automatically if a vulnerability returns.
