Depends a lot on your budget and the nature of your hosting.

Assuming that you're some retard who doesnt want their pirated movie stache deleted, the most secure option is to buy your own small server box put a password on it and never tell anyone about it and be secure via absolutely irrelevance.

And at the high end, lets say you're Jefferey epstien 2 and dont want your global child sex trafficking ring discovered, well then your best bet is to buy a real server rack and set it up for intranet or direct access only.

If for some reason you're unwilling or unable to do that, or ultimately your site needs to be connected to by a bunch of people of varying levels of clearance. Your best bet is probably cloudflare. Cloudflare gets hacked pretty often but you're probably safe again via irrelevance.
