The Best Free SFTP Servers for SSH File Transfers
UPDATED: March 13, 2024
An SFTP server enables secure file transfer using the Secure File Transfer Protocol (SFTP). It allows users to securely connect to the server, authenticate themselves, and transfer files between their local system and the server over a network. In order to use SFTP, a Client application and a Server application are needed to create the connection and facilitate file transfers.
SFTP servers are widely used in various industries where legal compliance requires secure file transfer (e.g. healthcare) and scenarios where secure file transfer is essential such as web hosting, server management and secure backups.

The JSCAPE MFT service can be integrated into Web pages, providing visitors with an interface to upload files.
The Web client can also be set up in a self-service Web page to enable downloads. The JSCAPE package includes a plugin for Microsoft Outlook, which can restrict the pool of files that can be attached to emails to those that are held in a specific folder.
Who is it recommended for?
JSCAPE MFT is suitable for large businesses because although its task automation features save time, they need technical experts to set them up. The system interfaces with your access rights manager and it can work with Active Directory, LDAP, NTLM, PAM, SSO, and RADIUS. This makes secure access enforceable and cuts down the risk of hacker access.
