Security & WAF
5,545 of the 1,000,000 top sites in our Tranco top-1M census run Imperva (0.6%). A web-application firewall and bot-mitigation service used to filter malicious traffic and block attacks. Detection is homepage-level HTML/header fingerprinting, so a site can run Imperva on other pages without it showing here.
