Bittium SafeMove Comms is a quantum-safe, end-to-end encrypted communications platform for government agencies, defence forces, and critical infrastructure organisations. It covers voice, video, and messaging on Android, iOS, and Windows, and is built on a zero-trust architecture that customers can run on-premises, in air-gapped networks, in the cloud, or in isolated tactical environments.
