The Best Free SFTP Servers for SSH File Transfers

Best SFTP Servers

Marc Wilson 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.

Here is our list of the best SFTP Servers:

1. Files.com Cloud – FREE TRIAL

File devices

Files.com gives you an awesome cloud tool that allows your company to have a Branded/Company portal for sending and receiving files over a Secure connection (SFTP, etc). The Single interface for file transfers gives you the security, flexibility, and ease-of-use of an enterprise-grade solution at an affordable rate.

When we tested Files.com we found the following key features.

Key Features:

  • Multiple File Transfer Protocols: Files.com supports various file transfer protocols, including FTP, SFTP, and AS2, providing flexibility for different use cases.
  • Mobile Apps: Access your files and collaborate on the go with mobile apps for iOS and Android.

  • Unique Links for File Upload/Download: Users can generate unique links for file upload/download, facilitating easy sharing with clients and customers.
  • Data Retention Rules and Permissions: Data retention rules can be set for users, groups, or folders.

A distinctive feature of Files.com is its ability to offer a secure file-sharing experience. This includes features like secure link sharing, file expiration and automatic detection, and anonymous file drops.

Why do we recommend it?

Files.com is mainly recommended for its user-friendly interface. Anyone, without technical skills can learn how to use Files.com without much training. In addition, Files.com is also ideal for secure file sharing and for its range of flexible features such as legacy and modern file transfer methods like SFTP and FTPS.

On top of these advanced Security features, Provisioning new users can be completed via Enterprise Identity (SSO). SSO gives you the ability to further authenticate and authorize users via LDP, Active Directory, Azure, ADFS, OneLogin, Auth0 and Okta along with many other identity providers.

Who is it recommended for?

Files.com is recommended for freelancers and small-to-medium businesses. It is specially recommended for those working remotely or with distributed teams, and for any company that needs secure file management.

During our testing, we identified the following pros and cons related to Files.com.


  • Easy File Sharing: Files.com simplifies file sharing with secure links. You can share files with anyone, even if they don't have a Files.com account.

Then you can let their system cope with the traffic volume of distributing many copies over the internet. This cuts down the amount of traffic that your network has to cope with, particularly for promotional material that you need to send out to many recipients. Add in the free trial and you get the best free SFTP server available on the market.

2. ExaVault – FREE TRIAL

In the course of our testing we found a unique feature with ExaVault.

One distinctive feature of ExaVault is its reliable and straightforward API. ExaVault’s API is valuable for integrating its services with users' own applications and workflows.

Why do we recommend it?

ExaVault is recommended for its ease of use and reliability. Its interface is easy to navigate and use, making it accessible even for those who are not technical. Plus, it is also worth mentioning that ExaVault provides a combination of SFTP and cloud file storage.

This is a good system for transferring large files. There is no limit to the size of files that can be uploaded to the ExaVault platform. From there, you mail out a link rather than sending a copy of the file. This link invites the recipient to access the file on the ExaVault server.

As all file access is carried out on the ExaVault server, the actions performed on them can all be logged. This is a great feature for businesses that need to comply with data protection standards.

The file transfer system and the cloud storage space are protected with encryption.

The system administrator needs to create user accounts that grant access to the file space. This allows each account involved in an access attempt to be written into the activity logs.

Who is it recommended for?

ExaVault is especially popular among businesses that require secure file transfers and collaboration with clients and partners. Additionally, ExaVault offers competitive pricing (for its MFT), making it an attractive choice for small to mid-sized businesses.

During our testing, we identified the following pros and cons related to ExaVault.


  • Free Trial: ExaVault offers a free trial period, allowing users to explore and experience the platform's features before committing to a subscription.

JSCAPE MFT provides SSH-based SFTP and SCP for file transfers and has the ability to run many other protocols. The list includes FTPS, HTTP, HTTPS, WebDAV, and TFTP. Not all of the file transfer options are secure and those protocols that don’t include encryption and authentication procedures should only be used on the network.

When we tested JSCAPE we found the following key features.

Key Features:

  • Self-Hosted System: JSCAPE MFT is a self-hosted system, allowing organizations to have control over their file transfer infrastructure.
  • Secure File Transfer Protocols: The platform supports secure file transfer protocols, including SFTP (SSH File Transfer Protocol), SCP (Secure Copy Protocol), and FTPS (FTP Secure).
  • EDI Protocols: JSCAPE MFT supports Electronic Data Interchange (EDI) protocols, facilitating standardized and secure electronic data exchange between trading partners.

Why do we recommend it?

JSCAPE MFT provides a Web-based client, which is hosted on the same computer sas the central server for the package. This means that all users can be provided with a client without needing to install one on each computer in the business. One central system is easier to configure and control.

JSCAPE has its own speedy file transfer system, called the accelerated file transfer protocol (AFTP). This isn’t a secure system but it can be useful for moving large files across the network to a location where they can be served securely. The package also provides two options for EDI message transfers. There are AS2 and OFTP2.

JSCAPE has a no-code scripting system that enables transfers to be embedded in task automation processes. This enables pre-processing of files for validation and post-processing stages, such as technician notifications or data import procedures. 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.

During our testing, we identified the following pros and cons related to JSCAPE.


  • Web-Based Client: The platform offers a web-based client that can be embedded in web pages, providing a seamless and integrated file transfer experience for users.
  • Outlook Plugin: JSCAPE MFT provides a plugin for Outlook, allowing users to efficiently manage email attachments through the platform.
  • Compliance with Security Standards: The platform is compatible with various compliance standards, including HIPAA, PCI DSS, SOX, and GDPR, ensuring that file transfers meet regulatory requirements.


  • No Price List: One limitation is the absence of a publicly available price list, making it challenging for potential users to assess the cost of adopting the solution and compare it with alternative options.

JSCAPE MFT will run on Windows, macOS, Linux, Solaris, AIX, and z/OS. Access a demo of JSCAPE MFT to qualify for a 7-day free trial.
