FTPS
FTPS is FTP over SSL. The FTP client first establishes an encrypted SSL link to the server and then runs FTP over the SSL channel. The login/password exchange and all data transfer is encrypted.

FTPS is supported by most dedicated FTP clients, it is not supported by Internet Explorer. Generally FTPS works first time, however some tweaking may be required to deal with restrictive corporate firewalls.

There are no settings for FTPS on the control panel as it is enabled by default for all users on an FTPS enabled account.

SFTP
SFTP is not strictly speaking part of the FTP protocol. SFTP is an FTP-like command set for transferring files over SSH (secure shell).

SFTP is supported by many FTP clients. It is also available from the UNIX command line (or other systems that provide an SSH client). SFTP is therefore often used in scripted file transfer applications. It may be easier to address firewall issues with SFTP as it only uses one port (port 22), whereas FTPS (like FTP) uses a standard port and a random port.

SFTP is not enabled for each user by default and at this time can not be enabled from the control panel. You need to mail support@maytech.net to get SFTP enabled for a login. We aim to get the controls onto the panel soon.

SCP
SCP is less widely supported by FTP client software, but maybe useful from the command line. In most other respects it is very similar to SFTP.
