The tension between maintaining personal privacy while still letting employers secure phones has been in the spotlight recently with former U.S. Secretary of State Hillary Clinton's use of a single device and a home-based server for both her government work and private communications.
A poll by IBM showed that 63 percent of all officials need access to specific software such as for finances and controlling on their mobile devices. However, many government officials and executives have resisted the use of so-called crypto phones as they tend to limit what users can do with them.
For instance, making a secure call requires both sides to have the necessary technology installed, and many programs aren't allowed to run on them because they may pose a point of entry for viruses or snooping software. The devices also tend to be more expensive than off-the-shelf phones.
Secusmart tries to make its devices safe and useful at the same time by installing a small chipcard, which encrypts voice and data and cannot be corrupted by malware targeting the operating system. The company has shipped BlackBerry 10 devices modified in such a way to German Chancellor Angela Merkel and members of her government.
Samsung has begun emphasizing its enterprise products as it lost its lead in the smartphone market to Apple in the fourth quarter. Its Galaxy S6 phone will ship with the Knox software, which combines improved user authentication and encryption to protect the device from attacks.
"Together with IBM and Samsung, we're closing the remaining gap" in Germany's security network, Secusmart Chief Executive Officer Hans-Christoph Quelle said in a statement. "German federal authorities will have the most modern and most secure communications network in the world."
