Things to be done after installing CyberPanel on VPS

Hi awesome community. It is a general question but very important to the newbies. I have migrated all my sites to the VPS server ( Vultr ) where I have deployed CyberPanel already. All are working fine and I'm happy with the performance but I just thought about what are the security measurement I should take and moreover if there are some important steps should I follow after migrated to the VPS server. But there is no guide available on the web for newbies who really have no idea about CyberPanel and VPS. Please suggest the steps or important things to be considered or things to be done after migrated to VPS with CyberPanel or suggest the link if there is any guide already available online that can help manage the compelete environment right way.

Your time and help will be greatly appreciated.
