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?

Opnsense firewall at perimeter...and that's about it. Chances of anything getting in with no exposed ports is pretty slim so I don't really bother with anything more.

For SSH exposed servers/VPS I do change the port though. Cut down log noise & maybe dodge the odd portscanner or two
