CloudFlare customers

CloudFlare customers

Over 2,000,000 websites globally use CloudFlare as their 24/7 web operations solution providing CloudFlare with an unparalleled amount of web performance and security knowledge. CloudFlare uses this performance and security knowledge to optimize every visitor request in real time. From mobile performance to regional networking route optimizations, or intrusion detection without impacting legitimate visitors to DDoS protection CloudFlare uses the learnings of the entire CloudFlare community to offer the next generation in enterprise performance and security.

In addition to a global content delivery network (CDN), full web content optimization, reputation-based security, and a cloud web application firewall, the CloudFlare Enterprise services include the following additional performance and security features:

Advanced DDoS protection

Layer 3 and 4

DDoS (distributed denial of service) attacks are on the rise. CloudFlare’s Advanced DDoS protection protects your website from a variety of Layer 3 and 4 DDoS attacks. Unlike other common DDoS solutions such as firewalls, routers and load balancers CloudFlare’s Advanced DDoS protection absorbs and stops the attack at CloudFlare’s edge before it ever reaches your server. Your network and servers are automatically protected from a range of TCP floods including SYN, UDP and ICMP attacks. Never install another piece of hardware or software, and never worry again about bandwidth and overage fees.

Layer 7

Sudden surges in traffic are often difficult to manage. CloudFlare layer 7 DDoS protection offers your website automatic protection by constantly monitoring and reacting to changes in your site’s traffic patterns. Leveraging an unparalleled amount of data contributed by the CloudFlare community, our systems distinguish between surges in traffic that are beneficial for your website—such as your website’s appearance on a major television program—and malicious attack traffic. When an attack is detected CloudFlare’s system automatically blocks the attack at the edge before it ever reaches your server and, most importantly, ensures that legitimate visitors to your site are still allowed access. Layer 7 protection from CloudFlare requires no hardware or software, and we never charge bandwidth or overage fees. 24/7/365 layer 7 DDoS protection is included with every Enterprise plan.

Keyless SSL

While most customers are comfortable with CloudFlare managing their private keys, some have unique security requirements making this impossible. Keyless SSL allows users to retain control of keys while still routing encrypted traffic through CloudFlare's global network. This means that for the first time ever, an organization can use a solution such as CloudFlare to get all of the benefits of the cloud (DDoS attack mitigation, load balancing, WAN optimization), without having to give their SSL private keys to a 3rd party cloud provider.

Railgun™ web optimization

Railgun provides web optimization and delivers content faster to your visitors

Railgun ensures that the connection between your origin server and each CloudFlare data center is as fast as possible. It does this by using an array of techniques to accelerate the HTTP connections between CloudFlare and your servers.

HTTP is now 23 years old and, although it does allow for object caching a large proportion of the web cannot be cached. Dynamically generated, rapidly changing, and personalized pages are not stored in caches and must be delivered from the origin server. Once speed-of-light related latency is considered the time to deliver these non-cacheable pages becomes significant.

Railgun helps eliminate the speed-of-light latency and cache the uncacheable by using a combination of compression techniques to achieve, on average, 99.6% compression of previously non-cached web objects. This results in a 730% performance increase on average, for web traffic from a web server to CloudFlare's network. No matter where the origin server is, or where the web browser is located, Railgun ensures that pages are delivered at light speed. Truly get the most out of your network.

Enterprise features

SSL encryption

Enable SSL with either a SSL certificate issued by CloudFlare or by uploading your own dedicated certificate to the CloudFlare network. We allow for upload of any SSL certificate type including Extended Validation (EV) SSL.

Keyless SSL

Keyless SSL allows users to retain control of keys while still routing encrypted traffic through CloudFlare's global network. This allows companies to get all the benefits of the cloud (DDoS attack mitigation, load balancing, WAN optimization), without having to give their SSL private keys to a 3rd party cloud provider.


Enable Websocket to create a persistent full-duplex protocol providing low latency client-server communication without the overhead of HTTP. Websockets make dynamic data blazing fast.

Customized pages

Customize all system messages and error pages with full HTML and CSS to reflect your business’ brand.

Additional Page Rules

Page Rules provide you with fine-grained control of CloudFlare on each page of your site. You can enable full HTML caching, individually customize CloudFlare’s features on a page by page basis or enable edge network forwarding to improve page delivery even further.

Purge by Cache Tag

Cache Tags provide a powerful way to purge the cache granularly using tags you define in assets' response headers. Purging the cache by Cache Tag is quick; a purge takes just a few seconds to take effect globally.

Custom mod_security rules

Allow CloudFlare to manage your mod_security rules from our edge without the overhead of actually running mod_security, including OWASP compliance rules.

Service Level Agreement (SLA) - 100% uptime

Industry standard SLAs often feature 99.999% uptime, also known as the five 9s. At five 9’s your website could be offline for as long as 5 minutes and 26 seconds each year. All CloudFlare Enterprise plans offer guaranteed 100% uptime because we know that anything less than 100% is an impediment to your organization’s success.

Email support

Priority email support for any issues or questions that might arise.

Phone support

24x7x365 phone support for any issues or questions that might arise.

2500% guarantee

This extended Service Level Agreement guarantees 100% uptime, and adds a multiplier to owed service credits resulting from any lapse: 5 times any downtime minutes and 5 times customers affected = 2500% guarantee.

Dedicated account management

Dedicated account manager to personally address your web operations needs, and answer any questions that may arise.

Invoice-based billing

Pro and Business plans are billed using credit cards. Enterprise customers will receive a monthly invoice.
