Do you use/know of a solution that enables encrypted (zero-knowledge) document collaboration?
Preferably real-time, such as Google Docs.
I'm working with a new client where I am the IT security sub-contractor.
We had our first meeting today and started working on a plan to do job itself.
The client requested that there would be a very high standard of security regarding many of the documents (mainly their threat response security protocols).
This got us thinking about how we can collaborate on documents securely, preferably in a real-time manner.
I took it on myself to find different solutions, and the best one I found is this:

This solution enables you to seamlessly collaborate on Google Drive, encrypted, with a minimal footprint. No special browser or software needed (only the gateway, hosted or on-premise).
Any thoughts?
What do you use?
