Cloudflare
A global CDN and security platform that makes websites faster and protects them from attacks.
Cloudflare is a global network that sits between your website and its visitors: it speeds up page loads by serving content from servers close to each user, and blocks DDoS attacks and malicious traffic before they reach your site.
Cloudflare is a CDN (Content Delivery Network - a network that delivers content from servers distributed around the world) and web security platform founded in 2010 by Cloudflare, Inc. When a site is connected to Cloudflare, all traffic passes through Cloudflare's servers first: clean traffic is forwarded to the site, while malicious traffic is stopped along the way.
On the speed side, Cloudflare caches a site's static files - images, CSS and JavaScript - in data centers across more than 300 cities. A visitor receives those files from the geographically closest location rather than from the origin server, which makes pages load noticeably faster. Cloudflare also compresses files and serves them over modern protocols such as HTTP/2 and HTTP/3.
On the security side, the platform provides automatic protection against DDoS attacks (attempts to overwhelm a site with artificial traffic), a WAF (Web Application Firewall), bot filtering and free SSL certificates. The site's real server IP address stays hidden, so attackers cannot target the hosting directly.
Cloudflare is a commercial company, but it offers a genuinely capable free plan: CDN, DNS, SSL and baseline DDoS protection all work at no cost. That is why it is one of the most widely used infrastructure services on the web, powering everything from small blogs to large enterprise sites.
Frequently asked questions
Cloudflare is a global network that sits between your website and its visitors. It does two main jobs: it caches your site's files on servers around the world so pages load faster, and it blocks malicious traffic (DDoS attacks, bad bots) before it ever reaches your site. Founded in 2010, it now handles traffic for millions of websites.
