For the safe download of files from a server we can use SFTP. To make this simple we use FileZilla, which can be downloaded for Mac from here.
In order to connect to the servers we use Termius to connect via SSH. Termius can be downloaded for Mac here.
You can find the connection details for the servers in 1password. If you need access to a server that you can't find in 1password then please speak to a 1password Admin as you may have not access to the relevant vault.
Use these details to create a new SFTP connection. In Filezilla open the site manager. You can either do this with the icon in the top left or by clicking on File > Site Manager.
