Whisper Systems produces security and privacy software applications for mobile communications devices running the Android operating system. The company was co-founded by Moxie Marlinspike and Stuart Anderson.
Products
Whisper Systems has produced RedPhone and TextSecure, which both allow for VOIP phone and text communications that are not detectable. RedPhone and products played a role in protester communications during the Arab Spring uprisings. Using RedPhone, Egyptians used the encryption software to call and make posts onto Twitter. It has also developed a firewall and tools for encrypting other forms of data.
Acquisition by Twitter
On 28 November 2011, Twitter announced that has acquired Whisper Systems for an undisclosed amount. Immediately following the acquisition, Whisper System's RedPhone service was made unavailable, and has not yet been re-released. However, some have criticized this removal, arguing that it was "specifically targeted people under repressive regimes" and that it left people like the Egyptians in "a dangerous position." Whisper System's TextSecure software, however was still made available as Twitter made the encryption program open source by releasing its source code.
