An overview of how BunkerMail does secure document exchange.
BunkerMail Explaination
BunkerMail is a cloud-based secure document exchange platform that looks like web mail.
Users send and receive encrypted messages and documents using a web browser, an Outlook Plugin, or a desktop application to access their secure communications.
Here's an overview of what makes BunkerMail Secure:
Alternative: Secure FTP

Better Alternative: HTTPS with Database Encryption
One improvement on SecureFTP is to use HTTPS or SSL to upload files to a server and then encrypt them into a Database using AES. This covers encryption-in-motion and encryption-at-rest, but leaves open a hole where the server has a plaintext copy of the files at the point where the file arrives or departs the server. Also, there is one key to encrypt the database and therefore a single point of compromise for the entire system which is out of the user's control:
