Virtru Dev here:
Virtru does host the keys, but not your data. We will fight any government request for keys described here: http://blog.virtru.com/faq-on-government-surveillance/
For the more technically savvy users, we are making the key manager open source and available for private use. By hosting your own keys and those you communicate with will have to contact your key server to decrypt your message.
Additionally, we are working on Public Key wrapping for keys that come into our system. Then keys hosted at Virtru have the same guarantees as PGP, but is much more user friendly to use.
Biting the hand that feeds IT
