Started off by

Enabling unattended updates
Enable only ssh login with key
Create user with sudo privileges
Disable root login
Enable ufw with necessary ports
Disable ping
Change ssh default port 21 to something else.

Got the ideas from networkchuck

Did this on the proxmox host as well as all VMs.

Any suggestions?

Block outbound traffic too.

Open up just what you need.

Segment internally and restrict access. You don't need more than SSH to a Linux Server, or perhaps to it's web interface for an application running on it.
