What is FTP, SFTP, & TFTP? These are protocols that are used to transfer files over a network. FTP (File Transfer Protocol) is the language that computers use to transfer files over a TCP/IP network.

What Is FTP?
FTP is short for File Transfer Protocol. Using the client/server model, FTP supports the direct transfer of files between your chosen FTP client and your web server.

FTP uses two separate channels to transfer information: a command channel and a data channel. By default, both of these channels are unencrypted, which means malicious actors could potentially eavesdrop on the information that you’re transferring.

What Is SFTP?
SFTP is short for SSH File Transfer Protocol, though it’s also commonly called Secure File Transfer Protocol.

SFTP offers the same basic function as FTP, but it uses tunneling and performs file transfers over SSH, which is different from FTP’s client-server and direct transfer approach.

So, what is SSH?
SSH, short for Secure Shell, is a cryptographic protocol that offers secure access to a machine (your server, in this case) over unsecured networks.

SFTP only uses a single channel and lets you authenticate your client using either a username/password or SSH cryptographic keys.

What’s the Difference Between FTP vs SFTP, Then?
The key difference between FTP vs SFTP is that SFTP uses a secure channel to transfer files while FTP doesn’t.

With SFTP, your connection is always secured and the data that moves between your FTP client and your web server is encrypted. This means that malicious actors can’t sit in the middle and intercept your data – everything you transfer is always encrypted.

With FTP, you need to authenticate with a username and password when you initially connect. However, the data that passes between your web server and FTP client isn’t encrypted, which means that a malicious actor could theoretically eavesdrop on that information.
