SFTP Servers

SFTP is an acronym for SSH File Transfer Protocol. Transferring files through an SFTP server is one of the safest ways to transmit data online. With an SSH FTP server tool, you can transfer files securely over an encrypted SSH connection.

Encrypting files with an SFTP server can prevent unauthorized access (which can help with things like HIPAA compliance). Many SFTP servers come bundled with SCP, which also protects files via SSH.

FTPS Servers

FTPS is an acronym for File Transfer Protocol over SSL, another secure alternative that lets you encrypt FTP transfers with SSL.

Many products combine FTPS and SFTP servers into one software program so you can choose the type of protection you need when transferring files. In this guide, we’re going to look at the top SFTP and FTPS servers on the market.

JSCAPE MFT implements SFTP, SCP, and FTPS within its client and server pair. The client isn’t distributed, but it is held on the same computer as the server unit. The users access the client over the network, or even across the internet, through a Web browser. The client includes a document viewer, which removes the need to transfer a file.

When we tested JSCAPE MFT we found the following key features.

Key Features:

  • Web-based client: Access to the remote computer
  • Runs on z Series mainframes: One of very few MFTs for z/OS
  • Secure Transfers: SFTP and FTPS
  • Transfer Scripts: File processing before and after transfers
  • EDI Protocols: AS2 and OFTP2

Why do we recommend it?

JSCAPE MFT offers SFTP, FTPS, and SCP for secure transfers. It is also able to move files through HTTP, HTTPS, and WebDAV. The client for the file transfer utility is Web based and hosted together with the server. The client can be accessed by users who have been granted usage rights in the corporate access rights manager, which also provides file access authorization.

The secure file transfer system is able to perform internal transfers and invite uploads or downloads for external users. The MFT package can also manage corporate syncing policy and organize local non-secure transfers, such as TFTP for network device configuration image movements.

The JSCAPE package includes a plugin for Microsoft Outlook. This limits the files that can be accessed for attachments. For example, the tool can limit access to a specific folder. Another feature in the service is the ability to transfer EDI messages with AS2 and OFTP2.

JSCAPE has created a fast file transfer system, called Accelerated File Transfer Protocol (AFTP). This isn’t a secure protocol but it can be used to move large files within the organization to a DMZ for distribution to outsiders.


Who is it recommended for?

JSCAPE MFT is a comprehensive package that offers many different channels for file movements and includes task automation features. These attributes will be particularly useful for large organizations. suitable for use by large organizations. MFT logs all file movements and controls access through the corporate access rights manager. These features make the package suitable for businesses that follow HIPAA, PCI DSS, SOX, or GDPR requirements.

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


  • Standards Compliance: Good for GDPR, HIPAA, PCI DSS, and SOX
  • Multiple OS Support: Runs on Windows, macOS, Linux, z/OS, and Unix
  • Cross-Platform Operation: Run scripts on different OSs around a transfer


  • No Cloud Storage: Doesn’t include staging space

The software for JSCAPE MFT is available for Windows, macOS, Linux, Solaris, AIX, and z/OS. You can get a free demo of JSCAPE MFT and a 7-day free trial following the demo.


JSCAPE MFT is our top pick for an SFTP and FTPS server because it implements many other protocols as well as those two secure systems. Transfer files internally with TFTP and the Accelerated File Transfer Protocol, move files over the Web with WebDAV, HTTP, or HTTPS, or send EDIFACT messages with AS2 or OFTP2 with this package. The software for JSCAPE MFT is available for a wide range of operating systems; it is one of the few extensible file transfer systems that will run on z/OS. The tool lets you construct scripts for pre- and post-transfer file processing and that opens up the option to create your own task automation services. Vary the security of a file transfer system from tight access controls on admin tasks to open access for delivering files to the public in a DMZ. You can also set up upload pages for outsiders.

2. Files.com SFTP Service (FREE TRIAL)

Files - Users view

Files.com is a cloud-based file platform with a built-in FTP and SFTP server. Being based on a remote server, this service is able to offer many more features than a traditional SFTP server. The Files.com system consists of cloud storage that acts as a buffer for all file activities.

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

Key Features:

  • Cloud Platform: Provides storage space for files
  • User Accounts: Enables file ownership
  • Mediated Transfers: Upload and forward
  • Link Invites: Removes the need to send files
  • Transfer Security: SFTP

Why do we recommend it?

The Files.com service encourages you to upload files onto the provider’s cloud platform and email out links instead of sending out copies. The advantage of this strategy is that it allows your company and each individual user to maintain control over how those files can be accessed and revoking permissions means that the former recipient doesn’t get to keep a copy of the file. All transfers, storage, and viewing are protected by encryption.

Files.com can operate with FTP and SFTP in three different ways.

Files.com itself can operate as an inbound FTP and SFTP server, allowing you and your users to connect to your Files.com account via SFTP. This allows you to use SFTP to access any portion of your Files.com account, even folders that are syncing to other providers, such as Amazon S3, Google Cloud Storage, Azure Blob Storage, Box, Dropbox, Wasabi, etc.

You can Mount an external FTP or SFTP site directly into Files.com as a folder. Files.com acts as an FTP or SFTP Client in this context, making that SFTP site available via the Files.com web interface, API, SDKs, and even other inbound SFTP connections.

You can configure a scheduled Sync, where Files.com will synchronize its copy of a folder or folders on a one-way or two-way basis with the external FTP or SFTP server.

Businesses can use Files.com as a pass-through when sending files to outsiders, storing a backup on the server in case of loss. It can also be used as a collaboration file storage – enabling several users to access and edit a document. Given that files can be left on the Files.com server, it can also be used as a backup service for important system files.

Files.com supports Single Sign On (SSO), Two Factor Authentication (2FA), Data Locality, Data Retention Management, Management Delegation, Audit Trails, Non-Repudiation, HIPAA, GDPR, and everything else needed for a secure and compliant Cloud Managed File Transfer solution.

The security offered by Files.com enhances transfer protocols because it enforces two-factor authentication for file access and uses the typical SFTP -strength protection for files during transmission.

File devices

Who is it recommended for?

Although there is a requirement for a minimum number of user accounts, which is five, the per-user charging of Files.com is a very scaleable service that is accessible to businesses of all sizes. The integration of the Microsoft 365 productivity suite and collaboration features means that this is a good cloud drive option for distributed teams and virtual offices.

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


  • Reduces Traffic: Mail out access links instead of files
  • Team Collaboration: Create shared folders for shared files
  • Traceability: Control access to files and block copying
  • Good for Large Files: Avoid failed transfers of large files
  • Remote Access Security: Browser security for access


  • No Native Productivity Suite: Connect to Microsoft 365 or Google Workspace

Files.com is a subscription service with a charge levied, per user, per month. The service is offered in three plan levels: Starter, Power, and Premier. The Starter plan requires a minimum of 5 users and provides a throughput of 1 TB per month. The Power plan includes a data throughput limit of 5 TB per month and requires a minimum of 15 users.

  • Link Invites: Invite others to view a file in situ rather than sending it
  • Encryption Security: Protects file at rest and in motion


  • No Native Productivity Suite: Need to connect to third-party tools

When we tested Rebex Tiny SFTP Server we found the following key features.

Key Features

  • Secure Protocol: SFTP
  • No Cost: Free to use
  • For Windows: Not available for macOS or Linux

Why do we recommend it?

Rebex Tiny SFTP Server is a free tool. It is a lightweight and secure file transfer utility that is ideal for securing the movements of small files. As the name suggests, this is a secure replacement for the Tiny File Transfer Protocol (TFTP), which is usually used for transferring configuration files to network and IoT devices.

Rebex Tiny SFTP Server

The tool is ideal for enterprises that need a simple SFTP solution rather than a complete SFTP server. While Rebex Tiny SFTP Server is an excellent tool it is important to note that it stores passwords in cleartext.

That means you can see passwords on the main server form, making Rebex Tiny SFTP Server inappropriate for users looking for a secure solution. It’s free for personal and commercial use. You can download the software for free.

Who is it recommended for?

Network administrators are probably using TFTP to move configuration images at the moment and should replace that facility with Rebex Tiny SFTP Server. The time has gone when network administrators could rely on the security of a private network. You should ensure strong file encryption on all of your file movements even within the confines of your LAN.

During our testing, we identified the following pros and cons related to Rebex Tiny SFTP Server.


  • Uncomplicated: Only one user account, so not something you would give to end users
  • Activity Logging: Helps with compliance management
  • Small Footprint: Won’t use up CPU


  • Ugly: The interface could do with an update

Rebex Tiny SFTP Server is a great lightweight SFTP server. If you want to conduct quick transfers without worrying about completing any hefty installations or configurations then this is the tool to use.

However, if you want to transfer sensitive information then the plain text disclosure of passwords is likely to be a deal-breaker. Rebex Tiny SFTP Server is available for Windows.
