Introduced 'I'm Under Attack Mode,' a new security level that adds an additional set of protections against potentially malicious HTTP traffic. This mode presents an interstitial page to visitors for approximately 5 seconds while automated security checks are performed, requiring JavaScript and cookies. It is designed to not negatively impact SEO or known legitimate visitors, and data from failed checks is fed back into Cloudflare's system to enhance traditional protections.
