Infosec startup Ionic Security raises $25.5M from Google, Kleiner

Congrats to Adam & Team!

I saw a very early demo when Adam was still building Social Fortress, and it was a plugin that encrypted all content being posted to the web (Facebook, Twitter etc) by default, and decrypted it only for those clients who had the plugin installed.

It's hard to tell how exactly Ionic works now. The website is somewhat light on details, perhaps intentionally. I'd really love to find out how Ionic's platform works.

Does anyone know of a consumer product for Dropbox that does something like this?
