Serv-U is an FTP server program with an easy graphical interface that can be run on most versions of Windows. The advantages of this program are that it is very easy to create a FTP server with user groups, passwords, etc. for the novice user (and the advanced user as well) and, on the other hand, that it can be highly customized to use different ports, SSL, and many more options. Serv-U is considered a highly secure FTP server. Security related issues are normally resolved very quickly, often within 24 hours.
