I'm not satisfied with the backup. The website files, ownership, and permissions on Plesk aren't clear at all. We need monitoring for the websites. For some sites that aren't up-to-date, any attackers could upload malicious codes to the website. There isn't any kind of monitoring for malicious codes. I would also like some kind of protection for the applications we put on the server. These wouldn't be normal firewalls, but firewalls that check the logs of the websites and issue an email with an alert when something wrong is happening to the website. There should be some sort of firewall that is specified for app protection. I have also faced some difficulty in moving the websites away from Plesk. Plesk doesn't work in synchronization mode. There's no ability to transfer configurations from old servers to new servers.
