What is FTPS?
FTPS, also known as "FTP over SSL” or “FTP with Security”, is a secure file transfer protocol that was a result of a much needed layer of security to add to the anachronistic FTP (file transfer protocol), while keeping the original protocol relatively unchanged. As an analogy, FTPS is to FTP like HTTPS is to HTTP.
FTPS ports
FTPS offers two methods to apply encryption to the FTP session and they use different ports. The first method is called the implicit method in which the client connects to the server’s port 990, which offers only encrypted sessions, and after logging in, another channel for data is opened over other ports depending on the server’s mode.

The second type of connection is called the data connection. This is the connection through which an FTP server exchanges file listings and transfers files. When an FTP client uses the control connection to instruct an FTP Server to send a file listing or transfer a file, the actual data exchange takes place on the data connection. The data connection is usually where most of the confusion and problems arise for FTP server administrators.
What is the difference between FTP and FTPS?
The main difference between the FTP and FTPS ports’ usage is the expected security behavior of clients and servers communicating through them. A server that receives a request via Port 990 will immediately perform an SSL handshake, because connection via that port implies the desire for a secure connection ( Implicit security).
