What is "blackphone"

The Blackphone is a smartphone built to ensure privacy that was developed by SGP Technologies, a wholly owned subsidiary of Silent Circle. Originally, SGP Technologies was a joint venture between the makers of GeeksPhone and Silent Circle. Marketing is focused upon business users, stressing that employees often conduct business using private devices and services that are not secure and that the Blackphone service readily provides users with options that ensure confidentiality when needed. Blackphone provides Internet access through VPN. The telephone runs a modified version of Android called SilentOS that comes with a bundle of security-minded tools. On 30 June 2014, the Blackphone began to ship advance orders.
