CloudFlare’s global network has 14 points of presence around the world. Once a website is part of the CloudFlare community, its web traffic is routed through CloudFlare’s network. CloudFlare offers many performance and security services including CDN (content delivery network), web content optimization and a web security layer.
Security service: CloudFlare’s network blocks threats and limits abusive bots before they hit the server, which means less wasted bandwidth and server resources. CloudFlare’s network gets continually smarter with each new website.
