FTP User Isolation is a great way to lock down your FTP site and prevent users from accessing resources they are not supposed to. Regardless if your server is providing shared hosting or dedicated hosting, FTP User Isolation can be leveraged for greater FTP security. It is particularly beneficial in hosting environments when you have a limited number of IP addresses to utilize but have several users requiring FTP access. In this case you’ll want to create 1 master FTP site and configure user virtual directories. Alternatively if your web server has several IP addresses available then one will typically deploy FTP Publishing on each site being hosted using a dedicated IP address. FTP user isolation in this case is not as critical but can still be implemented if you need multiple users accessing different folders on the same site.
