The File Transfer Protocol (FTP) is one of the original internet
protocols used for the transfer of large files. The modern internet has a
number of tools to transfer files such as email attachments and various
transfer websites, but those methods have their limitations. FTP, with
added security such as that offered in SFTP and FTPS, is still one of
the best tools for transferring files. But, to use it, you’ll have to
set up an SFTP server. Here’s our top list of the 10 best SFTP servers
out there.
FTP File Transfer Protocol: The original protocol and its major limitation is that it sends logins and data unencrypted. Login information, as well as the file itself, are sent “in the clear” in plain text that an observer can see.
FTPS File Transfer Protocol Secure (also known as FTPES): This is secure FTP, where the S in this case represents Transport Layer Security (TLS) encryption. This is essentially a basic FTP server that knows how to negotiate an encrypted TLS tunnel to transfer data through.
SFTP Secure File Transfer Protocol: This is also secure FTP, but in this case the S represents Secure SHell (SSH). This isn’t really an FTP server at all. Rather, it is an SSH server that understands FTP commands. Login information and files are transferred encrypted via SSH. To make matters even more confusing, the original intention of the abbreviation SFTP was Simple File Transfer Protocol defined by RFC 913, but has been relegated to “Historic” status and no longer used.
SCP Secure Copy: This is not an FTP protocol, but it is widely used to securely transfer files, so it bears mentioning here. SCP is a very simple file copy from one machine to another using the SSH protocol. The FTP protocols have a wide range of file management abilities that SCP does not.

The SolarWinds SFTP server download is a zip file that extracts into an MSI installer. Once the install is complete, setting it up is as simple as launching the program and specifying a few options such as allowed protocols and allowed transfer options.
There’s also a built-in SCP server which makes sense since both SFTP and SCP use SSH to accomplish their tasks. You can configure the SolarWinds SFTP server to also allow SCP by selecting “Both” protocols.
On the users tab, you can create user accounts and specify details such as which network interface to use.
MORE INFORMATION ON THE OFFICIAL SOLARWINDS SITE:
www.solarwinds.com/free-tools/free-sftp-server/
During installation, you can chose to run FreeSFTP as-needed, or you can install it as a system service. The latter means it will run all the time and be available for your SFTP users.
Ensure that you download the latest version (greater than 1.0.11). A vulnerability was discovered in version 1.0.11 which has been patched in 1.0.12 and the current version is 1.0.13.
Syncplify is an extensible SFTP servers which can run custom scripts. If you find that you have to jump through hoops to fit your SFTP server into your unique workflow, Syncplify may be the tool you’re looking for.
The free/evaluation edition has all the features of the Ultimate edition, but it only accepts a single connection and is not licensed for use in Production.
The Rebex Tiny SFTP server is free for all uses, including commercial use. It runs on WIndows XP up to Windows 7, and also supports Windows Server 2002, 2008, and 2012 editions. It is limited to a single user, but comes packed with features. It requires no setup, and contains full logging capabilities as well as support for public/private key logins instead of passwords.
It’s also worth mentioning that Rebex provides full .NET libraries to allow developers to include SFTP code in their own apps. The libraries are not free, but worth a look if you’re a .NET developer with a project like that on hand.
zFTPServer is built for enterprise Windows environments. It has full Active Directory login integration and is Microsoft Server 2012 R2 certified. It supports IPv6, account expiration, and a host of other features that enterprise Windows administrators will appreciate.
The free version has no feature limitations so it can be used as-is for smaller implementations. There are some account related restrictions, however. The free edition has is a limit of five total accounts, and three active connections at any given time.
The ALTools website provides a suite of products for systems administrators and regular computer users. ALTFTP is an FTP server that support SFTP and runs on a wide variety of older and newer hardware, even as far back as the Pentium 150. It is a Windows only FTP server, supported from Windows 98 onwards to to Windows 7. Presumably, it will run on Windows 10 as well, but that is not specifically listed.
There is just a single download for ALTFTP that bundles the client and server application together, and it comes with a 60-day free trial.
CrushFTP is Windows-based FTP server that leverages compression, hence the name “Crush”. It compresses the files being transferred and streams the compressed data across the network, greatly reducing transfer time for many types of files.
CrushFTP also has some security measures built in. It can protect from brute-force login attacks by automatically banning attacking IPs, and the robust user management includes virtual file systems and permissions inheritance. The CrushFTP server has a 30-day trial and the client is always free.
Cornerstone MFT(Managed File Transfer) is an SFTP server that addresses enteprise requirements. MFT is an umbrella term that indicates a higher level of control and audit than normal ad-hoc FTP client/server relationships normally provide. The advent of MFT was to address the need for transparent logins, higher security during transfer, and more visibility into file transfer progress and success or failures.
Cornerstone offers PGP-encrypted file storage. Data can be encrypted on the fly so there is never a point where unencrypted data is waiting on the disk to be encrypted. In addition, Cornerstone provides perimeter protection mechanisms such as two-factor authentication.
You can give Cornerstong MFT a try with its 30-day trial version to see if it fits your needs.
Globalscape’s EFT server can be deployed in a high-availability (HA) configuration including load balance and cluster configurations. In addition, Globalscape offers both on-premise and cloud products, so you can select the best EFT solution for your situation.
There is a 30-day free trial for Enterprise and SMB. While there is a free trial for the Cloud version as well, it’s not clear how long the trial period is.
Titan FTP Server supports regular FTP, as well as FTPS and SFTP. It is HIPAA compliant, which makes it ideal for use in hospitals and government agencies across the globe. It runs on Windows Server 2008 and Windows Server 2012.
In addition to simply providing file transfer services, Titan FTP server bundles some security measures which can defend against brute-force attempts, and full auditing capabilities so system administrators know what is happening on their servers.
Account management can be tied into Windows NT/SAM authentication in the Enterprise Version, and fine-grained account management such as automatic account expiry is included.
Titan offers a 20-day trial of its FTP server.
In addition to the free/evaluation edition, Syncplify also offers a Micro SFTP server for Windows. It is a completely contained portable SFTP server that can be run from a USB stick. Unlike the free/evaluation edition of the full Syncplify SFTP server, the Micro server edition is completely free to use in any situation including production and commercial uses.
Assuming those restrictions are not in place, any SFTP client that can connect to port 22 on an SFTP server should work well.
16. MySecureShell
The
downside to the ease in which SFTP is so easily setup on most Linux
distributions is that also means SSH is just ready to go. That implies a
level of trust in your users which may not be commensurate with
reality. If you have untrusted or unknown SFTP users, you may want to
impose restrictions on what they can do on the system. There are many
ways to achieve this, such as only allowing the SFTP engine to run which
disallows regular SSH logins, or you can use an app such as
MySecureShell to do the heavy lifting.
MySecureShell supports access control lists, which are the heart of granular control over user access. It is included in many distribution repositories so you can just use your package manager to install it:
Many of the best-known Linux distributions run vsftp as their FTP server, which speaks volumes to its security and stability. Part of that pedigree may stem from the fact that the app’s maintainer, Chris Evans, has a history of discovering security vulnerabilities himself.
Vsftp is in most Linux distributions and can be installed via your package manager.
ProFTP is inspired somewhat after the Apache webserver. You can mostly see this in the format of the configuration files, and in the fact that it uses modules to load needed functionality. In this case, you’ll want to use ProFTP with the mod_sftp module loaded in order to attain SFTP functionality.
The ProFTP website provides a few example configurations to get you started on the right track.
FTP remains a very important part of the internet toolset despite the fact that it inherently lacks security. Much like the HTTP protocol has had TLS bolted onto it for security to form what we now call HTTPS, FTP has had both TLS and SSH merged into it in order to provide encryption and security. There are few other tools that so easily allow arbitrarily large file transfers. Many organizations will continue to use SFTP or FTPS for a long time to come.
There are no limitations with PureFTP; all features are available from the start. Among its more useful features is the ability to throttle connections in order to preserve bandwidth, run it in a virtual file system (“chroot” in *nix parlance), set upload/download limits and more.
VanDyke Software VSHell is an enterprise-level SFTP and SCP server for Windows and Unix. It supports SFTP, SCP, and FTPS, and includes very granular user access control.
The Windows version boasts an easy-to-use graphical installer and it can use various user authentication methods such as LDAP and public/private key pairs.
The Unix version supports virtual directories as well as fine-grained file permissions. File permissions can be set per user, or on the virtual directories themselves.
VShell comes with a 30-day trial.

Using OpenSSH
On a standard Linux system most valid users will be able to use any SFTP client to connect to the server and transfer files to and from their home directory. However, allowing remote user access is usually considered a security risk so many system administrators will disallow this access. The most most common ways to do this is to disallow users’ shell access, or block the SFTP port (22, same as SSH) to specified IP addresses.Assuming those restrictions are not in place, any SFTP client that can connect to port 22 on an SFTP server should work well.
$ sftp test-sftp@172.81.178.134
test-sftp@172.81.178.34's password:
Connected to 172.81.178.34.

ProFTP was built from the ground up out of a need to displace wu-ftp as a widely-used FTP server. Wu-ftp had become unwieldy due to years of modifications made necessary by insecurities in the app and eventually it became more productive to just build a new FTP client from scratch.ProFTP is inspired somewhat after the Apache webserver. You can mostly see this in the format of the configuration files, and in the fact that it uses modules to load needed functionality. In this case, you’ll want to use ProFTP with the mod_sftp module loaded in order to attain SFTP functionality.
