MetaDefender Optical Diode

MetaDefender Optical Diode serves as a deterministic isolation device which protects critical assets while allowing multiple data types to be transferred concurrently. The hardware-enforced, one-way optical link between the source and destination servers reliably transfers data over a non-routable protocol, ensuring complete security from network-borne threats. Optical Diode provides access to real-time OT data and enables secure IT/OT data and file transfers without the risk of introducing security threats to critical OT production networks and assets.

MetaDefender Optical Diode supports OPC UA and OPC Classic (DA, A&E) unidirectional data transfer.
