Bittium Tough Mobile™ 3 C
Absolute government-grade
mobile security with
military-grade resilience
Absolute security for trusted communications
Mobile devices are now mission‑critical — and mission‑vulnerable.
Organizations handling sensitive or classified information increasingly rely on mobile devices that are designed for consumer use, dependent on globalized and obscure supply chains, and optimized for speed to market and not long‑term trust. The result is a systemic risk for organizations’ critical operations.
Tough Mobile 3 C exists to remove uncertainty from mobile security by helping security and IT leaders to protect critical confidential communications, operational data, and personnel safety. All while ensuring usability, availability, and compliance.
It is a government-grade, security-first mobile device designed from the ground up for trusted communications in demanding environments. It combines tamper-proofed secure hardware, secure and hardened Android operating environment, and integrated security software ecosystem.
Designed for authority requirements from day one.
One device. Two worlds. Absolute security.
