Advenica Data Diode Engine is a stand-alone proxy software solution that enables efficient and secure data transfer through Ethernet-based data diodes. Combined with application-specific services, the product enables network segmentation solutions for a variety of installation environments. The latest version of the Data Diode Engine, v1.1, includes a new service with support for MQTT, the IoT messaging standard.

The Data Diode Engine MQTT service ensures a secure extension of the MQTT publish and subscribe architecture over a data diode. The service enables devices located on a critical network to publish telemetry data for client subscribers located on a different network without exposing the critical network environment.
