Are you after a free global CDN, DNS, DDoS protection and web security provider that can speed up and protect any site online.

Enter CloudFlare.

CloudFlare operates a highly-available global content delivery network that has security measures built into every layer and regularly clocks in lightning-fast speeds.

According to CloudFlare, on average a website using CloudFlare loads twice as fast, uses 60% less bandwidth, has 65% fewer requests and is more secure.

CloudFlare’s cheapest CDN plan is  0.00 per month (i.e. free!). CloudFlare has so far made more than 2 million websites across the globe faster and safer. Join today.

About CloudFlare

cloudflare logo

CloudFlare was founded by Matthew Prince, Michelle Zatlyn and Lee Holloway in 2009. Although CloudFlare started as a project designed to stop spammers from harvesting email addresses on websites, in 2009, the company’s focus shifted towards providing web security solutions.

With time, CloudFlare founders realized that security software was one of the factors behind slow site performance. This prompted the development team to find ways of improving site performance while at the same time offering solid Internet protection.

This is how the Content Delivery Network, site caching, and web security service that we now know as CloudFlare was born.

Try CloudFlare. It’s risk-free.

What is Cloudflare Used For?

CloudFlare provides a suite of products for optimizing website speed and security. This review is focused on their CDN — or content delivery network (CDN) — designed to optimize site loading times by acting as an intermediary between site servers and visitors. The CDN also offers security benefits.

How a CDN Speeds Up Your Site Delivery

Copies of your site are cached in datacenters spanning the globe. Your site is served to visitors from the geographic location closest to them.  At the time of writing, the company reports of operating over 150 data centers around the world.

CloudFlare uses a proprietary technology known as Anycast to route your visitors to the nearest datacenter from their current location. This, in turn, causes your cached website to open twice as fast the average load time. As an added bonus, CloudFlare optimizes site speed for visitors on an IPv6 network even if your server environment is still on the old IPv4 infrastructure.

You’ll Get Some Added Security Benefits, Too

Besides providing CDN optimization and site caching services, CloudFlare also blocks threats that might compromise your website or waste bandwidth and other server resources.

The software offers a host of security features that protect websites against security threats such as SQL injections, spamming, and DDoS attacks.

Cloudflare’s network spans 152 cities, including 22 locations in mainland China.

Free vs Paid Plans

When it comes to pricing, users will be happy to know that CloudFlare offers both a free version and several paid plans. The free plan offers full access to the global CDN, a broad range of security features, SSL encryption and powerful statistic reports about site traffic. However, it has a few caveats such as weekly site crawls, as well as an activation period and analytics updates that take effect after 24-hours.

On the other hand, CloudFlare’s paid plans, namely Pro, Business, and Enterprise, feature better site protection, more frequent site crawling, mobile optimization, and DDoS protection.

So while the free plan offers basic protection, but CloudFlare recommends its entry-level paid plan for professional websites.

There are instances where you may need the paid plan, but below we list what the free plan comes with:

  • Unmetered Mitigation of DDoS
  • Global CDN
  • Shared SSL certificate
  • I’m Under Attack™ mode
  • Access to Cloudflare Apps
  • Access to account Audit Logs
  • Web application firewall (WAF) with CloudFlare rulesets
  • On the higher end plans, you can upload your own custom shared SSL
  • 24/7 support only available on the top tier plan

How Easy is it to Set Up and Use Cloudflare?

CloudFlare is very easy to set up as long as you have a self-hosted website. Enabling the service on your website simply involves making a few changes to your domain’s DNS settings, a process that takes less than 5 minutes.

You’ll Get a Wizard

CloudFlare’s Wizard set-up takes care of everything step-by-step. So, there’s no need to change your site’s existing code or make any hardware and software installations.

How do I Set Up Cloudflare?

Here’s how to set CloudFlare up for your website:

  1. Sign up on the CloudFlare website
  2. Type your email address and password to create your account
  3. Enter your website domain and click Add Site
  4. CloudFlare will scan your domain’s DNS records in about less than a minute
  5. Once the scan is complete, click Next
  6. Choose the right plan for your small business website
  7. A list of all the DNS records is displayed and you can select the domains where you want to enable CloudFlare
  8. You’ll receive the CloudFlare nameservers for your domain.
  9. Head over to your domain registrar and update the nameservers for your domain with the CloudFlare domain servers
  10. Log back into your CloudFlare account to verify that CloudFlare’s Universal SSL records have been provisioned for your domain
  11. Your account is all set and the nameserver update will take about 72 hours. Your site won’t experience any downtime during this period.

After setting up CloudFlare, you can start to monitor traffic statistics for your website. Analytics data is usually updated every 24 hours on the free plan and at 15-minute intervals if you choose to go with one of the paid versions. CloudFlare offers an intuitive interface that can also be customized if you’re on the premium plans.

CloudFlare Security

When it comes to protecting your website and visitors, CloudFlare offers quite a few security features. For starters, the Reputation Threat module blocks malicious threats by identifying IP addresses.

CloudFlare also offers the ability to block IP addresses by range or country. This helps to keep already known threats at bay.

You don’t have to worry about bots crawling your website and harvesting email addresses because CloudFlare provides protection against content scraping. Other standard security features include SSL encryption, HTTP/2 as well as protection against DDoS attacks, SQL injections, cross-site scripting, and comment spamming.

Higher Tier Plans Offer Advanced Security Features

Higher tier plans provide advanced security features. For instance, if you’re on Pro the plan and above, your site will benefit from a Web Application Firewall and OWASP ModSecurity Core rule set. In addition, Business and Enterprise plans receive advanced layer 3, 4 and 7 DDoS protection.

What is a DDoS Attack?

A DDos attack aims to make a website or online service unavailable by flooding it with traffic. Such attacks usually take place against a targetted website from a network of computers known as a botnet.

A business targetted by a DDoS attack stands to lose huge sums of revenue during the time their website is unavailable.

What is a BotNet?

A botnet is a network of computers used to carry out a DDoS (Distributed Denial of Service) attack. BotNet computers are often used without their owners’ knowledge or permission. They are often recruited following the installation of malware on the machine.

Heartbleed Vulnerability

The Heartbleed bug is a vulnerability first discovered in 2014. It affects the Open SSL cryptographic software library and allows for the theft of information protected, under normal conditions, by the SSL/TLS encryption used online.

Cloudflare Response to Heartbleed Bug

After finding out about the bug, which had been on the internet for two years, Cloudfare started an investigation to see whether their private keys and those of their customers were at risk. They also started the Heartbleed challenge – a crowdsourced test designed to see if the company’s private keys could be hacked.

They found that within two hours a dedicated attacker could retrieve a private key from a vulnerable server. As a result, they then reissued all Cloudfare SSL certificates in a bid to patch the problem.

What is HTTPS?

HTTPS is a secure and encrypted version of the regular HTTP protocol. Under a regular HTTP connection information is sent in the clear from your computer across the internet. However, this information is encrypted when HTTPS is used, meaning that it cannot be viewed by external parties. It is a combination of HTTP with SSL.

What is SSL?

SSL (Secure Sockets Layer) is secure a secure protocol that works on the top of HTTP to enable data security. In practice, SSL encrypted data is routed using protocols like HTTP for communication.

Two-Factor Authentication

Two-factor authentication is an extra layer of security which requires a user to have an extra piece of information along with their password. This often takes the form of a physical token or a message sent to a physical device such as a mobile phone.

It is particularly useful for small businesses that are worried about data security online. It means that even if your company’s password is hacked, crooks will be unable to access your data without additional authentication.

What Kind of Help and Support Does Cloudflare Offer?

If you ever need to contact customer service for technical assistance, CloudFlare offers both phone and email support. However, chances are that you won’t have to contact the support team thanks to CloudFlare’s comprehensive help center.

The help center comes replete with video tutorials, troubleshooting guides, and searchable knowledge base articles that provide answers to frequently asked questions.

If you want updated information about the product and company, you can also visit CloudFlare’s Community section to read blog posts and developer news.

What are the CloudFlare Pros and Cons?

CloudFlare has a great free offering, but there are a few drawbacks.


  1. In addition to optimizing site speed, CloudFlare also offers security features to protect your website from threats.
  2. The pre-loader can pre-cache your most popular pages to make load times much faster.
  3. CloudFlare notifies you if Google Analytics is not working properly.
  4. CloudFlare caches all static and dynamic content, including sub-domains, JavaScript, CSS, and images.
  5. The software tracks site traffic and generates analytics data to help you know how well your site and CloudFlare are doing.
  6. The setup process and user interface are both intuitive.
  7.  CloudFlare’s Always Online feature and CDN continues to serve a cached version of your website even if the main server goes down.
  8. There is a free version that lets you test CloudFlare’s basic features.


  1. Advanced security features are only available on the paid plans.
  2. The free version takes 24-hours to propagate and update analytics data. In addition, CloudFlare will only crawl your site update cached versions once a week if you are on the free plan.
  3. Stats and analytics are limited but still better than nothing. On the plus side, you can integrate Google analytics with CloudFlare to provide more detailed statistics reports.

The concept of combining web security and performance enhancing into a CDN is relatively new and there aren’t many products that offer both of these features. CloudFlare speeds up your website and protects it from security threats. While it may have a few cons as described above, this service is still a great option and even a cheaper than MaxCDN.

Overall, CloudFlare is worth trying if you need to optimize page load times on a content delivery network that does not comprise your website’s security or cost you a fortune.
