You should know how your web hosting providers respond should your website crash or get some operational challenges like how quickly they attend to the bugs.
You should find out how often they would back up the site and how they would protect your data theft and malicious file execution on the website.

I secure my website with security certificates. I also use security plugins on my websites. I think wordfence is a great plugin for WordPress.
