Despite shuttering its encrypted email service this year because it could not guarantee that it wouldn't be forced to turn over customer data when prompted by government requests, Silent Circle has pledged to continue to create ways to keep communications on mobile devices and video teleconferencing systems away from prying eyes. The Mountain View Calif.-based company has been aggressively addressing any fallout from the National Security Agency surveillance program revelations. It announced the formation of the Dark Mail Alliance in October, pledging to collaborate with other firms in developing end-to-end encryption technology to protect sensitive email messages. The goal is to create a new architecture and protocols that can defeat surveillance activities. Silent Circle was one of 10 security firms that debuted at RSA Conference 2013. With its iOS and Android apps, Silent Phone provides peer-to-peer encryption for VoIP calls and Silent Text encrypts text messages between users.
