Many organizations are faced with the increasingly complex task of managing mobile-device use among employees while still maintaining security.

Verizon Wireless and Cellcrypt have come together to create Voice Cypher, a powerful, cost-effective voice encryption solution that can be used on off the shelf commercial smartphones.
