No i will be using it personally but i want to minimize damage in case of a breach. I have set up a cloud app on SFTP. Works perfectly. But am quite scared about breaches.
So far all i miss is the key auth. Rest is already done. No one can change files but also not read my VPN details (as it is paid) or my password for root access or the username of root. I think it is okay then. I would need tho advice on the firewall thing on the other thread from you
