Whisper Systems was an enterprise mobile security company that was co-founded by security researcher Moxie Marlinspike and roboticist Stuart Anderson in 2010. The company was acquired by Twitter in November 2011. Some of the company's software products were released under free software licenses after the acquisition, which led to the creation of an independent organization called Open Whisper Systems.
