Data Diodes & Physical Layer OT Network Security
A data diode is hardware that lets data flow in one direction only. Operational data can leave a critical OT network for monitoring or IT systems, and nothing can be sent back in.
Xceltra supplies Blackbear's BIG9000 and DD9000 series, which enforce network separation at the physical layer and support industrial protocols such as Modbus and DNP3. They are used by utilities, oil and gas operators and other critical infrastructure.
