Whisper Systems Has Been Acquired By Twitter

Whisper Systems software as our users know it will live on
Posted November 28th, 2011.

We're moving:

We started Whisper Systems with the goal of improving security and privacy for mobile devices. We were attracted to this not only because we saw it as an opportunity to reinvent the security solutions that never really worked in the PC environment to begin with, but also because the stakes are much higher — due to the nature of mobile devices themselves — and we didn't like the way that things were looking.

We ended up tackling the full stack — all the way from application-level solutions at the top of the stack, down through a hardended version of Android, to kernel modifications at the bottom of the stack. Along the way we learned a lot, and developed products that we're proud of.

Now that we have been acquired by Twitter, we're looking forward to integrating our technology and our expertise into Twitter's products and services.

The Transition:

The Whisper Systems software as our users know it will live on (and we have some surprises in store that we're excited about), but there is unfortunately a transition period where we will have to temporarily take our products and services offline. RedPhone service will be interrupted immediately, but FlashBack users have a month to pull off any backup data they would like before that service also goes offline.

Enormous Thanks:

Thanks to everyone who beta tested our software, sent us encouraging emails, filed thoughtful bug reports, and in general kept us going with your enthusiasm and support. We couldn't have done it without you, and we hope that we can continue to meet your expectations for software that helps provide security and privacy.
