CDN

CDN technologies deliver a website or its assets from servers close to the visitor. The category mixes full-site networks in front of the origin (Cloudflare, Amazon CloudFront, Fastly, Google Cloud CDN, Netlify) and public script libraries a page loads from a shared host (jsDelivr, cdnjs, Google Hosted Libraries, Unpkg). Only the first group says something about the owner: a site behind Cloudflare or CloudFront has someone who configured infrastructure. This list is a stack qualifier rather than a buyer profile: hosting and edge platforms can target migration, security, WAF and DDoS vendors can find sites not yet protected, and monitoring services can qualify prospects by their delivery setup.
