FTPS (FTP over TLS)
What is FTPS (FTP over TLS)?
FTPS, or FTP over TLS, is a secure version of FTP that uses TLS encryption to protect authentication and file transfer traffic between a client and a server.
Examples
- A business partner portal uses FTPS so uploaded reports and login credentials are encrypted while traveling across the network.
- A hosting provider supports FTPS for customers who need to transfer website files without exposing usernames and passwords in plain text.

FTP was built to move files, but it was not designed for modern confidentiality needs. In plain FTP, usernames, passwords, commands, and file contents can be exposed to anyone who can observe the traffic. That is a serious weakness when the files or credentials matter.
FTPS was created to solve that problem by adding TLS protection to FTP. The goal is not to replace file transfer as a function, but to make that transfer safer. Instead of sending data openly, FTPS encrypts the communication so the client and server can exchange files with stronger privacy and better trust.
Summary 📝
FTPS is a secure version of FTP that adds TLS protection to file transfer sessions. It improves security by encrypting credentials and transferred data and by supporting certificate-based trust between client and server. Its main value is allowing organizations to keep FTP-style workflows while avoiding the major weakness of plain FTP, which is unprotected traffic.
