CloudFlare's mission is to make HTTPS accessible for all our customers. It provides security for their websites, improved ranking on search engines, better performance with HTTP/2, and access to browser features such as geolocation that are being deprecated for plaintext HTTP. With Universal SSL or similar features, a simple
CloudFlare aims to put an end to the unencrypted Internet. But the web has a chicken and egg problem moving to HTTPS. Long ago it was difficult, expensive, and slow to set up an HTTPS capable web site. Then along came services like CloudFlare’s Universal SSL that made switching
