Security & WAF
2,173 of the 1,000,000 top sites in our Tranco top-1M census run Citrix NetScaler (0.2%). An application delivery controller providing load balancing, traffic management, and security for web applications. Detection is homepage-level HTML/header fingerprinting, so a site can run Citrix NetScaler on other pages without it showing here.
