Data Diode DD1G by Advenica provides one-way data flow for Ethernet Layer 2. It is a hardware-only cybersecurity solution that protects valuable digital information. Engineered for enforced unidirectional data flow, it serves as a barrier against cyber threats, ensuring secure data transfer between intended networks without the risk of external attacks or unauthorized access. The DD1G is an Ethernet-based data diode with Gigabit performance. It features a purpose-built optical fibre connection that secures the separation of two connected networks. The Advenica DD1G series are pure hardware data diodes with no configuration options, eliminating the risk of faulty configurations or outdated software. The DD1G series operates on Ethernet Layer 2, automatically transferring all network data from the upstream to the downstream network, regardless of the overlaying network protocol. The data diode requires unidirectional network protocols, such as UDP. If other protocol support is needed, interfacing systems must act as proxy services to convert these protocols into a unidirectional flow. For bidirectional communication, the DD1G series can be combined with the Advenica Data Diode Engine, a standalone proxy software solution for managing data transfer through Ethernet-based diodes. The Data Diode Engine is optimized for secure data transfer and supports application-specific software services for file transfer and sensor data export.
