CloudFlare Overview


Global Network

CloudFlare protects and accelerates any website online. Once a website is a part of the CloudFlare community (spanning 23 datacentres around the world) its web traffic is routed through CloudFlare’s intelligent global network.



CloudFlare has over one million customers (including the likes of the Financial Times and StumbleUpon) and is adding 3,500 new customers per day. It carries more traffic than Amazon, Wikipedia, Twitter, Instagram and Apple combined and serves over 65 billion pages per month enabling it to carry the load of even the largest websites.

Top Performance

Top Performance

CloudFlare’s proprietary software allows it to process millions of requests per second efficiently, whilst its operation of its own network allows it to choose the exact location of its edge nodes: the most strategic points on the Internet. This is essential to ensure your visitors get the fastest page load times and best performance.




The delivery of your web pages is automatically optimised for best performance. CloudFlare also blocks threats and limits abusive bots and crawlers from wasting your server resources and consuming bandwidth. The result: CloudFlare-powered websites see a significant improvement in performance and a decrease in spam and other attacks.

By optimising the delivery of your web pages, your visitors benefit from great performance and fast page load times. A CloudFlare implementation not only improves your page load times, but blocks threats and limits abusive bots and crawlers which may be wasting your server resources and consuming your bandwidth.

CloudFlare Features

A next-generation solution that is reliable, simple to deploy and extremely effective. 

The CDN reduces hops and lowers latency; on average, a request is fewer than 10 hops and takes less than 30ms, meaning your website gains a global presence usually upheld by only the largest enterprises.

By automatically caching your static files at CloudFlare’s edge nodes, CloudFlare ensures your files are stored closer to your visitors and your dynamic content is delivered directly from your web server; by utilising a technology named Anycase, your visitors are then routed to the nearest datacentre. 

The result is that websites, on average, load twice as fast for visitors regardless of where they are located. These findings can be quantified by CloudFlare's analytics reports. 

Typically, a website on CloudFlare:

  • loads twice as fast for its visitors,
  • sees 65% fewer requests,
  • saves 60% of bandwidth.

CloudFlare’s charging model is independent of bandwidth consumption and therefore ensures that surges in website popularity or online attacks do not increase monthly costs.

CloudFlare CDN Features


Zero Configuration

CloudFlare technology saves you valuable time by building the cache based on your traffic and the objects on your site considered safe to serve from the edge, so you do not have to designate which files to cache.

Static and Dynamic Content

By caching static resources including JavaScript, CSS and images, and serving your dynamic content directly from your web server automatically. Subdomains can be selected individually so you can control which subdomains are part of CloudFlare’s CDN.

Page Rules

CloudFlare allows you to fine-grain control each page of your website through page rules functionality; by enabling full HTML caching, you can customise CloudFlare’s features individually on a page by page basis or enable edge network forwarding to advance page delivery.

Always Online

Building an Always Online™ version of your wesbite, cloudflare serves a limited copy of your cached website to visitors, should your server ever go offline, ensuring your most popular pages are always available.

Protection against traffic surges

Traffic surges can heavily imapct the performance of your website, in the case of a traffic surge, CloudFlare’s CDN absorbs the effect to ensure your servers stay online. On average, you’ll see 65% fewer requests to your servers and save 60% of your bandwidth.

Automatic IPv6

With the click of a button your site can be available on IPv6 networks which means you do not need to rush to upgrade your infrastructure. Your IPv4 infrastructure can remain in place until you’re ready; CloudFlare will make it seem to the world you’re running a modern dual-stack.

Rock Solid Reliability

CloudFlare ensure your visitors are unaffected by issues caused in any of their datacentres. Not only does their distributed network mean issues do not affect visitors to other datacentres, but if issues persist, vistors can be rerouted to the nearest datacentre for a seamless experienece.

Works with other CDN's

If you already use a CDN, CloudFlare works as a complement, providing you with two options: routing CDN traffic through CloudFlare first (saving money and bandwidth) or bypassing CloudFlare for your CDN traffic.

CloudFlare Security Features


Browser Integrity

Automatic browser integrity checks for all requests to your website, scan HTTP headers for threat signatures, should one be found the request is denied.

Save Resources

Serve your legitimate traffic with optimal performance from your threat-free server, as bandwidth and resources are saved.

Block and Trust List

Admins can add IP addresses, IP ranges or entire countries to Trust and Block lists, providing a nice addition to the automatic detection already in place.

Visitor Reputation

Every visitor establishes their reputation through various sources and through the threat data CloudFlare collects, you can defend your website. By controlling the type of visitors entering your site through the security settings, CloudFlare’s network automatically stops unwanted threats/visitors from entering your website.

Protect SSH/TELNET/FTP Ports

Add a layer of protection to ports like by disabling ports such as SSH, FTP and Telnet from your root domain. That way, you can add a layer of protection but continue to access the ports from a subdomain of your choice.

Collaborative Security

CloudFlare’s smart community works collectively, sharing information on new attacks to create a collective intelligence network, gathering information from every site to make the system smarter and protect the community.

Breaking the Cycle of Malware

CloudFlare websites inform visitors with compromised computers about malware attacks so that they can clean their malware infection.

CloudFlare Web Content Optimisation


The CloudFlare Optimiser helps to ensure every page renders quickly and efficiently, its features include

Easy on and off

Through an easy on and off button, it only takes one click to try each of the CloudFlare Optimizer services and one click to switch them off.


Real-time removal of nonessential characters from HTML, CSS, and JavaScript saves 20% of a files size. Autominify works without caching, supporting even fully dynamic pages.

Nothing to Install

Analytics unparalleled by other providers. 


CloudFlare provides indepth visitor analytics on your website traffic, allowing you to monitor threats and search engine crawlers which can make upto 20-50% of your traffic, meaning you get a true reflection of your traffic. Common analytics programs do not pick up unwanted visitors, Cloudflares threat control panel displays your threat visitors by severity, IP address, country of origin and type, allowing you to add or remove IP’s, IP ranges and countries in your Trust or Block list.

Cantarus were contracted to provide a SonicWall security and remote access solution to replace our legacy system. This was done in a very professional and timely manner, achieving all deliverables specified on the work order. Since then Cantarus have helped with other solutions in our company, building a global WAN with SonicWall appliances, and ongoing support and help. A business partner, not a reseller is how I would describe them. Looking fwd to working together with them in the future.

Lee’s recommendation of using cloud computing for our entire business IT strategy was a bold initiative that has stood the test of time and permits staff to connect to our business systems 24/7 from any location around the world with broadband connectivity. As a result our productivity has increased, with business continuity and disaster recovery assured. Lee’s detailed technical knowledge of all aspects of cloud architecture and connectivity methodology has been essential in the business achieving and maintaining an almost fault-free environment over the many years of operations.

Although we had virtualisation previously, at-least weekly we would lose connectivity, resulting in performance issues across the whole school. The solution Cantarus implemented has not only increased productivity in the school but it has resulted in less downtime and no need for maintenance.

R. Stent
Managing Director

Raffenday Limited

We have just completed a reconfiguration of several VPN links between our UK and Eastern European sites, as well as several UK home office workers to improve bandwidth and efficiency. Lee was my sole contact with this project and completed it in an efficient and friendly professional manner. I had some doubts at the start of the project that this type of configuration could be completed completely remotely. I felt that it would be necessary to be locally familiar with the client’s hardware setup and also their working practices. But Lee seemed to very easily establish a feel for the requirements and understand our needs and objectives. Based on his very professional and friendly service I have appointed Cantarus as our contracted support for all our Sonic Wall products.

I hired Lee and Cantarus to design a new website for our School. I cannot recommend Cantarus enough, they produced a professional looking website, which met our requirements exactly.

We have used Cantarus for Sonicwall support for nearly 12 months. During this time we have moved premises which obviously had implications for our Firewall configuration. Lee was available on a Saturday to reconfigure our devices and during this time each query we had was dealt with in so much detail that Lee not only resolved our issues to complete satisfaction, but also upskilled my colleague at the same time! Cantarus truly understand not only how to configure a firewall, but more importantly the implications to technology on our business. Invaluable.

We have been using a DotNetNuke website for several years and needed to upgrade the outdated site. I am very pleased to have chosen Cantarus to carry out the upgrade and transfer hosting to their servers. They have been easy to communicate with and have given good support throughout the process. I am now confident that ST*R Learning's website is in capable hands.

C. Thompson

Design Motive

Cantarus have hosted some of our DotNetNuke websites for a few years now. They helped us get up to speed with DotNetNuke itself in the early days, especially in regard to live deployment. Their Virtual Dedicated Server hosting is great value and has been fully reliable, and their multi-level backup system recently saved our bacon! We have always found their support to be fast, responsive and helpful. One particular day was so good I felt compelled to tweet about it.

S. Holmes

Absolutely delighted with our new website which Cantarus has delivered on DotNetNuke.

Our old intranet was clunky and under used so we wanted to develop a new intranet to improve information sharing and joint working across our charity. Following a tendering process Cantarus won the contract to build a new DotNetNuke based intranet for us. They have been great to work with, producing clear documentation and liaising effectively with our internal project team to ensure that everyone was on board and up to speed as the project progressed.

Working with Cantarus was smooth and efficient, we conducted a weekend migration to prevent disruption to the business and the planning phase was covered so well that the implementation was straight forward. Cantarus provided us with a centrally-managed network with increased availability and flexibility through a virtually constructed environment which was exactly the technology we had been waiting for.
