Twitter has acquired mobile security company Whisper Systems for an undisclosed amount, both companies have confirmed.
Whisper Systems' portfolio includes services such as Flashback, which offers encrypted backups for Android devices, and RedPhone, which provides end-to-end encryption for calls made on Android devices.
"We're looking forward to bringing our technology and our expertise into Twitter's products and services," says Whisper Systems' dev team in a blog post, adding that some services will be interrupted as the company transitions into a part of Twitter.
Whisper Systems is a small company, consisting only of two employees: security experts Moxie Marlinspike and Stuart Anderson. Marlinspike is the author of several well-known cyber security tools, including SSLstrip and wpacracker.
It's unclear what, exactly, Twitter plans to do with Whisper Systems, but it's not too far-fetched to imagine Twitter offering a service with an added layer of security to enterprise users.
