I open 443 and 80 on my router and forward it to a reverse proxy.

I have a couple of service that are exposed but most of them make sense only when I’m home so I whitelist private IP address on my reverse proxy.

If you do.your basic security such as updating your servers and services and not having dumb password, you shouldn’t be afraid. Think about it, all of the services that you use is exposed on the internet. I did work for big company and they don’t do much more than what you would probably do, except maybe having some automated monitoring that flag weird stuff. But hey, aside from bots, I don’t think Russian hackers are interested in your stuff. Stay low profile with your exposed things and it’s gonna be alright. Make sure you backup.
