SCP, by default, operates via port 22 much like SFTP and similar transfer protocols. Also much like SFTP, SCP runs on SSH and provides a simple and straightforward way, while still keeping security needs in mind, for transferring files from a host to a client. As the name implies, Secure Copy Protocol, SCP is straightforward in its purpose and design.
Here is our list of the best free SCP servers for Windows:
- SolarWinds Free SFTP/SCP Server This lightweight utility provides a graphical user interface that stores connection data for frequent connections. The service also includes TFTP and SFTP options and it is useful for managing the distribution of device configuration images. Runs on Windows.
- BitVise This SSH server isn’t completely free to use – just a 30-day free trial – but the corresponding SSH Client is free forever and both provide SCP and SFTP among other file management options.
- FreeSSHd This SSH server is a little dated and it actually offers SFTP rather than SCP. However, it is free to use and it provides a secure file management server. Runs on Windows.
- OpenSSH This long-running free SSH server is still being frequently updated and it provides a free SFTP and SCP service. Written for Unix, but it also runs on Linux and macOS. A Cygwin version will run on Windows.
Users often claim that it is faster than SFTP/FTP, transfers files from point A to point B, and does so securely. In fact, in a broad sense, SCP and SFTP/FTP are by and large the same thing and even operate similarly over SSH, but each still has its own particular nuances. Almost any server that offers SCP functionality will often offer SFTP/FTP as well, and even then it will often offer them in parity, providing the best of both worlds!
Most notably SCP is just plain faster than setting up an FTP server or indeed an SFTP server. On the flip side, SCP lacks some of the more robust features that SFTP/FTP supports for transferring files. This can ultimately result in a bit more legwork required in regards to directory management or worse, resuming broken transfers since SCP will leave you wanting in that regard.
In most other ways the protocols are all pretty much even with regard to functionality. For tons of files or complex directory configurations, SCP can really falter. Nonetheless, SCP perfectly fills a specific niche for quick and easy file transfers when there's still just a bit of need for security and something like TFTP just doesn't quite cut it!
The Best SCP Servers for Secure Copy Protocol Transfer of 2024:
Below you'll find a list of SCP server software that will help you set up a secure copy server on Windows 7, 8.1, 2008 Server, 2012 Server, and more!
Some of these are paid versions and others are free.
What should you look for in a free SCP server for Windows?
We reviewed the market for SCP servers for Windows and analyzed options based on the following criteria:
- Transmission security provided by Secure Shell (SSH)
- GUI interface and a command line option
- Additional SFTP file transfer option
- Session settings storage with a password locker
- Remote directory listing
- Free forever and not just a temporary free trial
- Useful secure file transfer service that can be used on demand or called as part of a task automation script
With these selection criteria in mind, we identified a shortlist of useful, secure file transfer utilities for Windows that provide a number of protocol options including SCP.
1. SolarWinds Free SCP Server
