CEO: Mike Janke
Based in Washington, D.C., Silent Circle develops software that encrypts communications on mobile phones and video teleconferencing services. The company 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.
The company also provides encrypted email service, encrypted voice and video calls from laptops and desktops, and supports encrypted calls between Silent Phone subscribers and nonsubscribers. This year, the company introduced a secure website for administrators to manage licenses for employees using the software.
Silent Circle was co-founded by Mike Janke, former Navy SEAL and best-selling author, and Phil Zimmermann, the creator of Pretty Good Privacy email encryption software.
