The Browsing Experience Security Check page has a <meta data-react-helmet="true" name="robots" content="noindex, nofollow"> tag, which excludes it from search engines results.
The page also seems to be delisted from Cloudflare’s in-site search.
This makes it hard to find the page, you’ll have to go through some third-party websites to find it usually.
It would be neat if search engines were allowed to crawl the page.
