Copying files over the internet comes with some inherent risks, thanks to the open nature of the internet. In order to securely transfer files, you need to use encryption.
FTP (File Transfer Protocol) is the non-secure precursor to the SFTP protocol.
The sessions that FTP uses are unencrypted and things like credentials are sent in plain text. It allowed for remote copies for uses such as web and file servers, but the lack of security led to alternatives, with SFTP being the most well-known.
Here are the 11 best SFTP servers:

We will look at some of the best applications to help you get your SFTP operations conducted in a safe and effective way.
Many people will say that standard FTP transfers are ok, and in some instances they are correct. However, there are times when confidential data such as financial information or personal records need to be transferred across insecure networks such as the internet.
In these instances, you cannot rely on unencrypted copying methods to move data. STFP is the answer in these cases for many reasons.
SFTP (Secure File Transfer Protocol) fixes many of these issues and adds a layer of security. Secure Shell (SSH) is the backbone of this application that allows for secure sessions to be established between hosts using a SFTP or even a SSH Client, as many of them have SFTP support.
There are many other advantages to using the SFTP copying method, which is why there are so many different programs out there that use it.
We have taken a look at 15 of these applications and their features so that we can show you the best ones for your potential requirements. Let us take a look!
