What is Secure File Transfer Protocol (SFTP)

SFTP (Secure File Transfer Protocol) is a way to safely send files over the internet. It adds a layer of security by encrypting the connection, so files like product images or spreadsheets can’t be seen or changed while they’re being transferred.

A brief history

SFTP first emerged as a more secure alternative to FTP in the early 2000s, as data privacy and network security became bigger concerns.

It gained early adoption in industries handling sensitive information like banking, healthcare, and government, where encrypted file transfer was essential. As ecommerce and digital systems expanded, SFTP became a standard way for businesses of all kinds to securely move product data, pricing files, and media assets between systems.

Today, it’s still widely used across retail, manufacturing, and supply chain environments for safe, automated file exchange.

Good to know

Using SFTP doesn’t automatically mean everything’s secure. You still need to manage access carefully, only give credentials to trusted users, and change passwords or keys regularly. It’s also smart to audit file activity from time to time so you know who uploaded what, and when.

Frequently Asked Questions

What’s the difference between SFTP and FTP?
FTP transfers files without encryption, which means your data and login info can be intercepted. SFTP, on the other hand, encrypts everything. It runs over SSH (Secure Shell), making it a safer choice for moving sensitive product or customer data.
Do I need special software to use SFTP?
Not necessarily. Many FTP clients like FileZilla, Cyberduck, or WinSCP also support SFTP. You just need to make sure you're connecting using the correct port and credentials. Some ecommerce or PIM platforms also allow direct SFTP connections for automated feeds.
How do I know if my server supports SFTP?
If your server runs SSH (which most modern servers do), it likely supports SFTP. You can check with your hosting provider or try connecting using an SFTP client. If the connection fails, double-check your settings or ask your platform admin.
