SFTP - FTP OpenSSH Server on Ubuntu 20.04 LTS is the best solution to transfer files and data securely over encrypted network layers (using SSH2 protocol).

Data can be achieved by using the Secure Shell (SSH) Protocol, which enables a high level of encryption even in insecure networks. Unlike FTP, only one connection is used and the user authentication, commands, output as well as data files get encrypted and kept safe when they encounter various attacks while being transferred.

Also, this FTP solution comes with support for multiple virtual servers and powerful access control rules, that enable you to hide/show files or directories based on wildcards, username, IP address, and time range.

If you want to manage your own FTP server, SFTP - FTP OpenSSH Server on Ubuntu 20.04 LTS provides you with every tool you need to create your server, manage and protect it.
