Why This Package Really Secures Your OT

1

Zero attack surface

The tunnel is outbound only: no ports are open to the Internet from your devices.

2

NIS2 / IEC 62443 Compliance

Segmentation, logging, and user-based access—the foundation expected by auditors.

3

Independent of the client network

4G isolates your access from the site's IT LAN: no need to coordinate with the client's IT department.

4

Siemens S7, Schneider M340/M221, Rockwell AB, Wago, Beckhoff — via serial or Ethernet.
