SFTP is a secure way to move files between computers or servers, and businesses use it because it protects data while it travels, verifies who is connecting, and gives teams a reliable way to upload, download, rename, or delete files on a remote system.
SFTP stands for SSH File Transfer Protocol, or Secure File Transfer Protocol. It runs over SSH, which means the connection is encrypted from start to finish. That matters when you are sending customer records, financial exports, website backups, product feeds, or any other file you would not want exposed in plain text. Standard FTP sends data and login details without that protection, which is why SFTP is the safer choice for modern business use.
| What SFTP does | Why businesses use it |
|---|---|
| Encrypts files and login sessions | Helps keep sensitive data private in transit |
| Uses SSH authentication | Lets you control access with passwords or SSH keys |
| Supports file management | You can upload, download, move, rename, and delete files remotely |
| Works well with automation | Teams can schedule recurring imports, exports, and backups |
| Fits many hosting setups | Common for websites, app servers, cloud storage, and vendor data exchanges |
In plain terms, SFTP is often used any time two systems need to exchange files on a steady basis. A law firm may upload documents to a secure server. A dental office may send data exports to a software vendor. An eCommerce store may push inventory feeds or download order files. A marketing team may use it to update website files, move media assets, or access backups on a hosting account. If your site runs on WordPress, solid WordPress hosting often includes SFTP access so updates and file recovery can happen without exposing your server through less secure methods.
Another reason SFTP stays popular is control. You can limit which folders a user can reach, revoke access when staff changes, and use SSH keys instead of shared passwords. That makes it a good fit for agencies, in-house teams, developers, and outside vendors who need file access without full server control.
SFTP is also different from HTTPS. HTTPS secures website traffic in a browser, while SFTP secures file transfers and remote file handling. If you are sorting out site security more broadly, our page on whether HTTPS affects SEO helps explain the browser side of that picture.
For most small and mid-size businesses, SFTP is used because it is private, dependable, and familiar to hosting companies, developers, and software platforms. If you need a website or server setup that includes safe file access, our web design services can help you build it the right way from the start.
