Possible

Hardware Data Diode design enforces traffic to flow in one direction: from input port (1) to output port (2) only.

Impossible

Hardware Data Diode prevents traffic flow from output port (2) to input port (1).

• ✓Hardware Data Diode accepts an input from one (1) SPAN Mirror Port and sends the traffic to the out-of-band sensor
• ✓Hardware Data Diode ensures traffic cannot flow in the reverse direction from the sensor to the network through the SPAN port

• ✓Hardware Data Diode accepts an input from one (1) SPAN Mirror Port and creates two (2) output copies of the traffic from the SPAN port
• ✓Hardware Data Diode sends the two (2) copies of the packets to two (2) out-of-band sensors - each sensor receives an identical copy
• ✓Hardware Data Diode ensures traffic cannot flow in the reverse direction from the sensors to the network through the SPAN port

• ✓Hardware Data Diode aggregates copies of traffic from two (2) SPAN inputs sending to two (2) connected sensors
• ✓Each sensor receives identical aggregated copies
• ✓Hardware Data Diode ensures traffic cannot flow in the reverse direction from the sensors to the network through the SPAN ports

• ✓Hardware Data Diode aggregates copies of traffic from eight (8) SPAN inputs sending to two (2) connected sensors​
• ✓Each sensor receives identical aggregated copies​
• ✓Hardware Data Diode ensures traffic cannot flow in the reverse direction from the sensors to the network through the SPAN ports

Hardware Data Diode Benefits

• •Ensures any ethernet packet flows in one direction out the monitoring ports
• •Maintain network integrity for industrial network monitoring and security without exposing additional risk
• •Protect the source of data streams like switch SPAN ports between network segments that have different security requirements
• •No risk of software failure
• •Keep OT networks compliant with industry regulations
• •Small form factor for space constrained deployments
• •Affordable pricing (when compared to software-based data diodes)
• •Install quickly and easily because it is unmanaged hardware
