NATO has approved the Dutch secure mobile phone Sectra Tiger/S 7401 for use at the NATO SECRET level. The solution has already been approved by the EU for use at the EU SECRET level.
Sectra Tiger/S 7401 was developed by Sectra under guidance from the Netherlands National Communications Security Agency (NL-NCSA).
Sectra Tiger/S 7401 also enables secure communications between different security domains. This means a user can securely communicate with colleagues in NATO, the EU and their respective national networks, with a single telephone, which is unique in the crypto industry.
