The security offered by IDriveSync will appeal to users who have concerns about services like Dropbox, which has suffered from well-publicized security pitfalls. And IDriveSync's offering is more complete than what you get from Boxcryptor. That service lets you add an encrypted folder to a cloud storage service you already use, like Dropbox or Google Drive, but it's not a storage service on its own, and it doesn't offer the private key-level encryption that IDriveSync does. IDriveSync offers both storage and security in one, and it does so with an added level of security that its rivals don't offer.
