We are in the healthcare industry and have deal with multiple vendors and clients. We have been using FTP to transfer files but we have been told that it is no longer secure enough. We need to install an FTP server in our network that has the following requirements:
1. Must be secure (FTP is not good enough)
2. We do not want to require everyone to get an FTP client. We want the end user experience to be as easy and elegant as possible. For example, one of our vendors has an ftp site that is accessed through https web page.
3. We do not want a web service (like box.net.)
