Bittium Oyj announced that it will launch a new Confidential classification level version of the Bittium Tough Mobile with its back-end system at Critical Communications Europe exhibition in Copenhagen, Denmark, February 8 - 9, 2017. Bittium Tough Mobiles unique dual-boot functionality for the Confidential classification level makes it possible to operate the device with two completely separate operating systems: Public and Confidential. The operating system classified as Public is meant for personal communications with access to e.g. social media applications. The operating system classified as Confidential is completely isolated and hardened for secure authority and information security use. The entity enables the user to have only one device for calls and messaging for both personal and for demanding information security needs, thus eliminating the need to carry two separate devices.
