Best SCP Server Software for Secure Copy Protocol Transfer

SCP Servers help you transfer files to and from servers, computers and other networking devices using a secure-tunnel via SSH.

Secure Copy, or SC in short, is a network protocol that supports file transfers between hosts on the same network.

It is based on the BSD RCP protocol and uses a secure shell (SSH) to transfer data. It also uses the same process for authentication, and this makes the data transfer both secure and confidential.

SCP is mostly used by IT administrators to copy files between servers and networking devices. It is installed in places where users connect to download or upload files. Since it is a popular component, it is available for Linux, Windows and Mac OS.

Here’s the Best SCP Server Software

SCP is popular among IT administrators to transfer data between devices in a safe and secure manner. It is typically used to transfer data over a non-secure channel such as the Internet. Since the SCP server is widely used, there are many companies that offer it today. Let’s look at some of the best SCP server software.
