CloudFlare is a Next Generation CDN
Faster
CloudFlare automatically caches static content:
- CSS
- JavaScript
- Images
- Requires zero configuration
- Provides high gzip compression
- Is compatible with other CDN solutions
Result: The average website on CloudFlare loads:
- Twice as fast
- Sees 65% fewer requests
- Saves 60% in bandwidth
What is a CDN?
CDN = Content Delivery Network
How it works:
CDNs serve content stored at servers closest to the visitor.
The result -> pages load faster
- CDN technology has been around a long time. The web’s largest sites use CDNs for performance.
- Until now, CDNs have been expensive and hard to configure.
Easy Web Content Optimization
CloudFlare makes web content load efficiently by:
- Consolidating multiple network requests into one request
- Loading JavaScript asynchronously
The result -> pages load snappier

Web Content Optimization
The webpage has evolved.
Today websites are made up of:
- Widgets
- Plugins
- Ad servers
- Twitter Share / Facebook Like button
- All of these plug-ins and widgets are JavaScriptbased
- Web content optimization makes sure the web page renders as quickly as possible

- Comment spam
- Content theft
- Email harvesting
- SQL injection
- Cross-site scripting attacks (XSS)

Web Threats Are a Pain
- Many bots doing malicious activities online
- Comment spam
- Content theft
- Email harvesting
- SQL injection
- Cross-site scripting attacks (XSS)
- DDoS attacks
- Until recently, each category required a separate and timeconsuming solution
- Most solutions are expensive and difficult to implement
CloudFlare’s Security System Learns
CloudFlare’s system automatically starts to block attack BEFORE it hits the origin server

CloudFlare’s Default Security is “Medium"
[image]
- Users can select the desired level of protection directly from their control panel
- Partners integrated via cPanel also have access to the “I’m Under Attack” mode
Stop Heavy Attacks From the Control Panel
[image]
- Sites under attack can choose "I’m Under Attack Mode” directly from their control panel
- Works by adding an additional set of protections to stop malicious HTTP traffic from being passed to the origin server
- Reduces bandwidth to the origin server
Free IPv4 / IPv6 Gateway
Smarter
Our customers can continue to host on IPv4 and be available on IPv6!

Why is IPv6 Compatibility Important?
- IPv4 addresses are running out around the world. As a result, there is a transition to IPv6 IP addresses
- IPv4 and IPv6 are not compatible with one another
- Today, 1% of web surfers are on IPv6 and can’t reach websites on IPv4. Their number is growing fast in Asia & Europe.
- To make website servers IPv6-compatible requires an expensive hardware investment
Always Online (Forget 503 Errors)
CloudFlare Always Online service keeps a cached copy of your customer’s website so it is always available, even if the server goes offline
