Not quite sure what types of phones the CIA or Secret Service Agents use, I would imagine it would be something like this, or better still, should be this. With privacy being its focus and main selling attraction, the Blackphone 2 is the smartphone of choice for encrypted communications. This mysteriously covert device features a 64-bit octa-core processor, 3GB of RAM, a 5-inch 1080p display, Gorillla Glass 3, and a MicroSD slot.
And now the good stuff. This particular handset features custom software named PrivatOS, which is where the device truly makes its mark. Users can configure multiple spaces either for work, personal, or top secret type use. Encrypted conversations can easily be had using Silent Text, Silent Contacts, and Silent Phone apps.
