Learn how Cloudflare enhances a customer’s security and performance and the steps to get started with Cloudflare.
Cloudflare is designed for easy setup. Anyone with a website and their own domain can use Cloudflare regardless of their platform choice. Cloudflare doesn’t require additional hardware, software, or changes to your code.
Cloudflare stops malicious traffic before it reaches your origin web server. Cloudflare analyzes potential threats in visitor requests based on a number of characteristics:
- visitor's IP address,
- resources requested,
- request payload and frequency, and
- customer-defined firewall rules.
A DNS lookup or ping of a proxied Cloudflare subdomain returns Cloudflare IP addresses. Cloudflare masks your origin IP address for proxied (orange-clouded) DNS records so attackers cannot bypass Cloudflare and directly attack your origin web server.

Cloudflare optimizes the delivery of website resources for your visitors. Cloudflare’s data centers serve your website’s static resources and ask your origin web server for dynamic content. Cloudflare’s global network provides a faster route from your site visitors to our data centers than would be available to a visitor directly requesting your site. Even with Cloudflare between your website and your visitors, resource requests arrive to your visitor sooner.
Cloudflare’s globally distributed anycast network routes visitor requests to the nearest Cloudflare data center. Cloudflare distributed DNS responds to website visitors with Cloudflare IP addresses for traffic you proxy to Cloudflare. This also provides security by hiding the specific IP address of your origin web server.
Also, our flat-rate pricing structure provides predictability and reliability in your CDN and DDoS bandwidth expenses. Cloudflare does not have bandwidth limits for domains on the Free, Pro and Business plans as long as those domains comply with our Terms of Service. However, your hosting provider may still impose limits on bandwidth usage and/or charge for bandwidth.
Note that additional terms may apply to:
- Self-serve domains with add-on features (contact firstname.lastname@example.org for additional details), and
- Domains in the Enterprise plan (contact your Cloudflare Account Team for further information).
