Arbit Data Diode 10 GbE
Arbit Data Diode 10 GbE
Hardware data diode that moves data from an open network into a closed one over a single fibre-optic link that can only send light in one direction, with two dedicated servers acting as sender and receiver. It supports mail, file shares, FTP, REST and video or radio streaming, and is certified to Common Criteria EAL7+.
Arbit Trust Gateway 10 GbE
Arbit Trust Gateway 10 GbE
Gateway for exporting data from high to low security networks, built to replace manual transfers by USB stick. Two data diodes in series create an isolated zone that holds configuration and program code as read-only, and the gateway checks content, authenticates the source and can require approval from a releasing officer.
C4ISTAR Gateway
C4ISTAR Gateway
Cross-domain gateway for importing and exporting data between security domains, sold in a server room version and a ruggedised version with NATO standard connectors for vehicle mounting. It supports NATO releasing and clearing officer functions, signature checks, SitaWare integration and national security profiles that customers can build themselves through an open API.

About

Arbit Cyber Defence Systems develops and manufactures cross-domain security hardware based on data diode technology, which lets organisations move data between networks of different classification with no path back. The company is based in Hvidovre, Denmark. It grew out of an idea founder Rasmus Borch had in 2006 to use standard high-speed fibre-optic network technology as a physical one-way diode, and the first Arbit Data Diode was built and tested in 2008.
