CellTrust SL27.59.2

CellTrust SL2(TM) is an enterprise-level application that works by assigning a Mobile Business Number (MBN) to keep personal and business communications separate on a single, Bring Your Own Device (BYOD) handset, enabling communications without using the employee’s personal telephone number. Built on CellTrust’s SecureSMS(R) and SecureVoice(TM) technologies, this seamless solution also enables a secure connection for internal communications between SL2 users. This application is vital for enterprise communications that need to meet eDiscovery and compliance requirements.
