There are many ways to secure your site and reduce your risk of being compromised. We used to alert only on the signs of compromise (like malware, SPAM, defacement, blacklisting, etc), but we started to give recommendations on Sitecheck that can help you harden your site.
We go through the basic best practices that every website should be doing and generate a warning if it is not completed.
Hopefully, it will help you on your journey to secure your sites.
Note that all our recommendations are done automatically on WAF, which can be easily leveraged by any web site.
