Secure Copy (SCP) are a safe and efficient way to transfer files over a network. Although it was initially developed in a Unix environment, SCP would eventually find its way into many other operating systems.
Today we will be looking at the Microsoft Windows variants of SCP. If you are wondering what you would need an SCP application for, or what they do, then this article will outline all of the most important aspects of SCP.
Why Use SCP?
SCP’s main feature is its security – It allows for encrypted file transfers through the Secure Shell protocol (SSH) using any of these SSH Clients.
Other protocols that don’t create an encrypted link between hosts before beginning a file transfer are more vulnerable to interception and interference by Packet sniffers and scanners that might be on your network or over the internet.
Another great benefit of using SCP as opposed to any other regular transfer method is the speed benefit depending on certain network conditions. If setup correctly, you can expect better transfer times which means less time waiting for files to finish copying.
But if you have servers and systems that require you to use other protocols like FTP and TFTP then you can find this functionality in some SCP applications too.
If you need to copy things over networks that are not secure, such as the internet, then SFTP or SCP are ideal.
Not having control over who can access your connection is an inherent risk of using the internet. The protocols that you use should have a secure layer integrated into them when you copy data between remote nodes. This applies to both the internet and networks.
Generally speaking, SCP is used to transfer files via a medium that isn’t secure. For example, if you’re looking to transfer files across the internet, SCP would be a good choice.
The reason is that the internet can be accessed by anyone so it’s a good idea to pick a protocol with inbuilt security. In this scenario, less secure protocols like TFTP would be unsuitable because they could be accessed by unauthorized users.
SCP is also used across a wide variety of devices as a means of delivering updates such as firmware and configs such as network switches, wireless access points and even IoT devices. With some scripting you can deploy these updates across your network without taking up too much time manually putting in the work per device.
Here’s the Best SCP Servers of [date]:
SolarWinds make a variety of monitoring tools for maintaining network stability, network administration and communications. They have also made a free SFTP and SCP app for easy file transfers.
There is a file size limit on transfers up to 4GB for simultaneous transactions. This is generally enough for standard file transfers when copying over files to devices on a production network.
This application lets you upload configurations to devices as well as copying files.
It has a simple interface that is easy to use, which means that almost anyone can use it to transfer files without needing to have too much technical knowledge. There are plenty of options for you to enable for the most optimal copying conditions across the network.
You can also specify IP addresses on specific subnets so you can use the app to transfer files across your environment.
If you would like to try out SolarWinds SFTP/SCP Server for yourself then you can grab it from the link below. There is a free registration that you will need to complete before you can download it.
This version is Free.
2. BITVISE SSH SERVER
BitVise is a good looking program that operates elegantly and effectively for completing SCP and SFTP tasks. BitVise also has its own simple user management system built into it, so you can grant and revoke access to specific files and folders without needing to create new users in your operating system, which is quite useful.
File sizing varies between 4GB and 6GB when copying data with BitVise, which may or may not suit your specific requirements depending on how much remote copying you intend on doing. It isn’t a bad idea to have additional overhead when specifying your SCP tools in case the need arises later own for larger file support.
BitVise is security focused, which is good news for people that need to use the software in a secure corporate environment. If you have a computer or server that does not need to send files, but only receive them, then you can set that up. This helps to combat exfiltration and data loss. You can specify that the application can accept remote connections or not as well, which adds to the security of the device.
BitVise is more than a single function application though, as it has a whole host of extra features built into the platform. It is very secure with the way it is able to specify which commands can be run remotely, and its user management interface is also very easy to use. This is a great choice for a secure network that needs to transfer large file sizes and volumes.

Not all applications need to be system resource hungry, and FreeSSHd takes this principle and runs with it. FreeSSHd is supremely light weight and works on the Microsoft Windows Operating System. This makes it an ideal candidate for deployment in most businesses because of the prevalence of Windows.
Another benefit of the application’s light weight operation is that you can use it on much older hardware, so that upgrading equipment is not necessary. Network performance is also very lightly affected during small to medium file transfers.
For the most part FreeSSHd will do exactly what you need it to thanks to its simple design, however most power users and advanced users might find its very basic interface a little lackluster and somewhat frustrating. But for the most part the clean design and easy use will mean that it is a good choice for most users.
The product itself hasn’t been updated in a very long time, so if you are concerned about any new vulnerabilities or exploits on the internet then you might want to try another application.
If you would like to try out this application then you can find the download page here.
The installation file is very small by today’s standards which fits in with the minimal system resource requirements of the application.
The application is free to use, but not open source. If you wish to purchase the license to use the source you can purchase it from this link here. Pricing starts at $229 without the source code, and $389 with the source code respectively.
OpenSSH operates as an SSH server and as an SCP server too. By using OpenSSH together with SCP you have a secure copying platform to transfer files safely and effectively. This allows you to copy files between computers, servers, remote computers and any other device that supports these protocols. The application is another piece of software that doesn’t require too many system resources.
OpenSSH operates entirely from the terminal interface, meaning that the program doesn’t have any graphical user interface. This means that users need to familiarize themselves with the text commands of OpenSSH and SCP. Luckily the command list is not very complicated to understand, so once you have mastered the basics then you will be able to use the program with very few issues. A benefit of using applications such as this in text mode is that you can script and code automated processes to complete repetitive tasks such as backups.
But if the application has no intuitive user interface then how is it so popular? The answer is in the application’s security stack. OpenSSH uses a multitude of different encryption standards such as AES and RSA, giving you peace of mind when you are connecting over the internet. Even the authentication process is encrypted, meaning that no sniffers or scanners will be able to intercept your login requests.
If you think that OpenSSH and SCP is the right kind of solution for you then you can learn more about the applications from here.
