How secure is the Blackphone?
Despite the extremely high levels of mobile security the Blackphone offers, Weir-Jones does admit that it is not invincible.
"Anybody who claims that anything is hackproof is clearly selling snake oil," he said. "What we do know is that the encryption on our tools is very, very good, but I'm certainly not going to guarantee that the thing is 100 percent perfect. That would be dramatically foolish."
The Blackphone CEO added that the company is on top of any known vulnerability and has response resources in place to act upon any issues, but a phone where all data is encrypted should have less hack issues that arise than others.
