Requirements:
Encrypted during transport
Encrypted at rest on the cloud
It does not need to be encrypted while sitting on my local system. The operating system handles that.
Browsable, like Dropbox. It doesn't have to sync on my file system like Dropbox does. I'm not looking for end-to-end encrypted Dropbox (which is what Dropbox should be). I'm OK with uploading.
Mobile app updated within the last 6 months?
Hosted. I don't mind installing and maintaining software, but would rather not maintain something with a security focus.
Is pricing transparent? If I have to talk to a salesperson, it's too expensive.
