Attacks on critical infrastructure are daily operations, often state-sponsored. Operational technology – power grids, railways, water treatment – needs protection that software alone cannot provide.

The application

Data diodes let process data flow out of the control network while making inbound attacks physically impossible. Fiber optical trip links and IEEE C37.94/G.703 converters provide galvanically isolated teleprotection between substations, and rugged variants withstand harsh field environments.

Typical deployments: substation teleprotection, one-way export from SCADA/ICS, isolated links across industrial sites. Trusted by operators such as Svenska Kraftnät, ABB and Alstom.

How it is built

One-way release from OT, with a controlled return

Out is the default. Anything coming back is a separate link with its own approval.
