In this tutorial we’re answering: What is SFTP? We’ll start with a quick review of FTP, then dive right into what is SFTP.

We’ll take the confusion out of SFTP as your file transfer solution.
What does SFTP stand for?
First, let’s review FTP or file transfer protocol.
FTP is a protocol for transferring data between a computer and remote computer or server over an Internet connection. Simply FTP facilitates data transfer through a client server relationship, allowing you to manage and transfer files from one system to another.
Now let’s take a look at SFTP and find out how it can help your business with critical file transfers.
SFTP stands for SSH file transfer protocol. While SFTP is a secure protocol for transferring files, the s stands for ssh or secure shell.
SFTP is a Separate Protocol
SFTP still uses a client and server connection to facilitate file transfer, but SFTP is a separate protocol. Unlike FTP, SFTP file transfers are done over the control channel. There is no need to open a separate data channel to complete you file transfer.
SFTP requires authentication by the server you’re connecting to and runs over an SSH session on TCP port 22. SSH or the secure shell acts as a privacy layer for your connection, establishing a secure channel between your local computer and a remote computer or server. This helps ensure that important information like usernames, passwords, and personal data aren’t sniffed by someone maliciously. Additionally, encryption helps ensure your data isn’t visible in plain text as it transfers over the Internet. With SFTP both commands and data are encrypted.
How do Businesses Use SFTP?
Why is SFTP a smart choice for business file transfer?
SFTP is pretty much the standard for the purpose of secure data transfer. Like FTP there are a lot of uses for SFTP, which makes sense since SFTP can be used by any industry for any file type.

Be it customer data, accounting and financial information, files that reveal internal operations, or agreements with contractors and government agencies. SFTP ensures secure and efficient file transmission, all without sacrificing security or compliance.
