Arbit's Data Diode holds Common Criteria EAL7 certification, and its gateways are accredited for NATO COSMIC TOP SECRET and EU TOP SECRET. Its Danish Defence work includes a long-term framework agreement with the Danish Ministry of Defence Acquisition and Logistics Organisation (DALO) for cross domain solutions, and a ruggedized gateway developed with DALO.
