Speed up and protect your site with Cloudflare

Making the Internet Work the Way It Should for Anything Online

Cloudflare speeds up and protects millions of websites, APIs, SaaS services, and other properties connected to the Internet. Our Anycast technology enables our benefits to scale with every server we add to our growing footprint of data centers.

Proxy Servers and CDN

A reverse proxy is a server that sits in front of web servers and forwards client (e.g. web browser) requests to those web servers. Reverse proxies are typically implemented to help increase security, performance, and reliability. In order to better understand how a reverse proxy works and the benefits it can provide, let’s first define what a proxy server is.

A forward proxy, often called a proxy, proxy server, or web proxy, is a server that sits in front of a group of client machines. When those computers make requests to sites and services on the Internet, the proxy server intercepts those requests and then communicates with web servers on behalf of those clients, like a middleman.

A content delivery network (CDN) refers to a geographically distributed group of servers which work together to provide fast delivery of Internet content. A CDN allows for the quick transfer of assets needed for loading Internet content including HTML pages, javascript files, stylesheets, images, and videos. The popularity of CDN services continues to grow, and today the majority of web traffic is served through CDNs, including traffic from major sites like Facebook, Netflix, and Amazon.

A properly configured CDN may also help protect websites against some common malicious attacks, such as Distributed Denial of Service (DDOS) attacks.

Predictable Bandwidth Costs
We believe that you should never be surprised by your monthly bill. Our flat-rate pricing structure makes your CDN and DDoS bandwidth expenses predictable.

Cloudflare provides insight to your website traffic that you can’t get from other analytics programs

In addition to visitor analytics, you can monitor threats and search engine crawlers. For most websites, these threats and crawlers make up 20% to 50% of traffic. It’s traffic every website should understand, but most analytics services ignore.

Cloudflare works with popular analytics programs, including Google Analytics. Cloudflare augments all the information that you already love from your current analytics solution with new information that you can’t get anywhere else.

Over 10% of all Internet requests run through Cloudflare’s network, giving us unprecedented insight into our customers’ web traffic. Our edge sees all requests made to a website, regardless of whether it’s cached or uncached, the user has adblock, or they turned off JavaScript. This enables us to provide actionable insights to our customers.

Insights

Enterprise Logs
For enterprise customers, we can provide consolidated logs from around the world. These are very rich, containing detailed information about every request and response.

Threats
When we identify requests that are threats, we log them and block them. That means we not only protect your site, but also provide insight into the malicious activity we’re seeing.

Analytics
At-a-glance Cloudflare analytics provides visibility into: WAF events, rate limited requests, Argo Smart Routing performance, bandwidth savings, visitor geography, DNS queries, and more.

Audit Logs
For enterprise customers, Cloudflare offers the ability to view and download the most recent changes made to domains or account settings, making compliance reviews and monitoring configuration changes easy.
