Security & WAF
2,302 of the 1,000,000 top sites in our Tranco top-1M census run AWS WAF (0.2%). Amazon's web application firewall, filtering and blocking malicious HTTP traffic to protect hosted applications. Detection is homepage-level HTML/header fingerprinting, so a site can run AWS WAF on other pages without it showing here.
