Terafence Email-Relay – TFG121

Where Every IoT Counts

Email is still considered as valid, useful communication method especially when the receiver is a human. Sending messages, errors, warning and as such is an operational requirement in OT environments, yet the traditional all safe keeping Air-Gap must be converged in order to deliver electronic messages from OT to external world.

Terafence secure email relay Solution keeps a Military grade network separation at the physical network layer and denies any attempt to reach the secured side. Unlike other data-diodes relying on optic fibers, Terafence have designed hardware chip to attain military grade protection.

Terafence Email-Relay Solution enables safely sending emails without any risk or exposure to outside Cyber threats, within an All-In-One compact desktop unit connected to both networks. The unit maintains the galvanic Air-Gap while forwarding data at 1Gbps from the secure side to the less secured side. No human intervention, no surprises.
