Over the years web hosting security has become a serious challenge for developers and administrators alike. With the constant platform changes, SSL requirements and security considerations, we are all forced to change and upgrade to keep up. FTP is no different.
We recommend using CoreFTP as your FTP client when connecting to our hosting environment. You can download it from their official site; http://www.coreftp.com.
CoreFTP has kept up with the current demands of the hosting world and, for now, is known to work with all of the systems in our environment.
