FTPS is an extension of File Transfer Protocol. It utilizes SSL encryption to increase the security of the file transfer.
If you want to transfer files using FTPS, three conditions must be met.
  1. The domain must be on a server with Plesk 11 or newer
  2. The domain must have a dedicated IP address (Please see How to Purchase an Additional IP Address for more details)
  3. The domain must have an SSL certificate applied to it
To Set Up FTPS
  • Log into Plesk
  • Click on Tools & Settings > Security Policy
  • Under Secure FTP select the policy that is needed (in most cases you will select either Allow Both or Per IP Address)
  • Skip to
  • Click on Tools & Settings > IP Addresses
  • Click on the IP address you want to enforce the policy on
  • Select the SSL certificate to use for encryption from the drop-down menu
  • Select the FTPS usage policy for the IP address
  • Click OK

Note: If you are able to download files from your site using FTPS, but can not upload to your site, there is a known TLS bug in Windows Server 2012 that requires a hotfix. You will need to check the box next to Windows 8 RTM to download the correct file. Please contact Support if you have any questions or concerns.
