Edit: thanks for all your help and replies, this is a such a great community!

I would like to host a public service for some family, probably Peertube so we can share some videos. Invite only.

There's no way I'm going to get everyone onto a VPN, it's a non-starter though I would prefer it.

I am thinking to use a VPS with anubis and either crowdsec or fail2ban (or both?!) in front of Peertube. Will apply as much hardening as I can muster behind that: things in containers, systemd hardening, SELinux/Apparmor enabled/tuned, separate users for services, the usual. All ports shut except 80/443, firewall up.

Despite all this I expect it will get scanned and attacked as it will have to expose ports 80/443 to the world so for family it will just work.

Is there anything else I should consider for security? Is Peertube the weakest link in the chain? (a little concerned their min password length is 6 it seems and no 2fa). So long as I keep whole thing up-to-date is it as secure as anybody can manage these days (without resorting to VPN)?

Is it all too much hassle and I should look for a company that offers hosted Peertube so they can worry about it?

Thanks for any and all advice.
