Security & WAF
2,235 of the 1,000,000 top sites in our Tranco top-1M census run Sucuri (0.2%). A website security service offering a web-application firewall, malware scanning, and DDoS protection. Detection is homepage-level HTML/header fingerprinting, so a site can run Sucuri on other pages without it showing here.
