-## Recommendations
-
-To prevent bot IPs from attacking a website:
-
-- A new website owner might set a _Medium_ or _High_ **Security Level** and lower [**Challenge Passage**](/waf/tools/challenge-passage/) to a value below **30 minutes** to ensure that Cloudflare is constantly protecting the site.
-- An experienced website administrator confident in their security settings might set **Security Level** to _Essentially Off_ while setting a higher [**Challenge Passage**](/waf/tools/challenge-passage/) for a week, month, or even year to provide a less obtrusive visitor experience.
