Physical Network Packet Data Diode

In critical sectors like energy supply, transportation, defense, and industrial manufacturing, protecting IT/OT networks from cyberattacks is essential, especially in applications demanding Safety Integrity Levels (SIL) 3 and 4. Implementing an air gap between OT and IT environments strengthens security by physically separating operational technology systems from external IT networks, significantly reducing the risk of cyber threats.

To enable operators to transmit data, such as sensor information, from OT networks to IT networks while maintaining the required air gap, a robust solution is necessary to securely bridge both environments.

The NEOXPacketRoo is a specialized solution bundle featuring a physical data diode that enforces full galvanic isolation between networks while allowing unidirectional signal transmission, preserving the critical air gap. To eliminate any attack surface on the physical layer, operators can either use their own data transfer methods leveraging the PacketRoo’ s diode functionality or utilize the NEOXSecureFile- Transmitter software, which provides secure, granular, and one-way file transfer from OT to IT.

The PacketRoo, combined with the NEOXSecureFileTransmitter, offers a scalable and high-performance solution for both Windows and Linux hosts, enabling seamless unidirectional data transmission. Each component of the bundle is also available separately, and if an existing data diode is already in place to bridge the air gap between networks, the NEOXSecureFileTransmitter remains fully vendor-agnostic. This flexibility also applies to the PacketRoo itself.

To reduce the risk of configuration errors, the PacketRoo is available only in fixed configurations, with no option to modify port settings after deployment. As a fully sealed system, it is designed for both civilian and military use cases, ensuring robust and secure operation.
