Whisper Systems was an American enterprise mobile security company that was co-founded by security researcher Moxie Marlinspike and roboticist Stuart Anderson in 2010.[1] The company was acquired by Twitter in November 2011.[2][3][4] Some of the company's software products were released under open-source licenses after the acquisition.[5] An independent group called Open Whisper Systems later picked up the development of this open-source software,[6] which led to the creation of the Signal Technology Foundation.[7][8]
