The CloudFlare service helps website owners secure and speed up their website for free, with additional features available for paying customers. They have perfected how to make a website secure by providing protection from a wide range of threats to keep your website safe.
What is CloudFlare?
The best part: As security threats change so does cloudflare, so you’re protected well into the future. CloudFlare handles all requests to a website to:
- Stop attacks directed at a website
- Dynamically modify content in order to improve performance
- Provide details about dangerous requests to your website
- Automatically determine what parts of your website can be cached, which makes everything load faster
- Provides a network gateway between protocols like IPv6 and IPv4 — This also means that your website will load faster
- Make installing SSL flexible and one-click easy — From a web developers perspective, this is awesome and saves a lot of time
The magic is performed at the DNS level, before the files on your web server are even loaded, so you’ll need to change your nameservers over to theirs in order for the service to work.
What security features are included?
Improving your website security can help you avoid troubles and headaches in the future. Whether it’s budget, time, or lack of understanding, many companies that rely on a public website don’t take the necessary precautions to secure their infrastructure. A security breach can not only compromise your data, or potentially your clients’, it can lead to a detrimentally negative stream of PR.
The following threats are checked to keep your website safe:
- Browser integrity
- Visitor reputation
- Block list / trust list
- Saved bandwidth and server resources
- Protect SSH / Telnet / FTP ports
- Collaborative security
- Breaking the cycle of malware
What Is an “Attack” on a Website?
Online threats range from nuisances like comment spam and excessive bot crawling, to malicious attacks like SQL injection and denial of service (DOS) attacks. The threats that exist are constantly changing — and growing. It’s a very difficult thing to keep up with, and as a web developer I know first hand how exhausting it can be.
How do I get started?
It’s ridiculously easy. Follow these simple steps:
- Create an account
- Transfer the DNS for the domain you want to protect
- Configure the options and save
That’s it, really. CloudFlare will help walk you through the steps.
How Does It Work?
CloudFlare acts as an internet-wide neighborhood watch program. It automatically detects new attacks that arise against any website on its network. Once CloudFlare identifies that there is a new type of attack out there, it starts to block the attack for the specific website and the entire community. This means the longer you are on CloudFlare, and the larger it gets, the better the protection becomes. It’s a truly ingenious way to combat website attacks. They definately know how to make a website secure.
Speed & Performance Benefits
Beyond security monitoring, CloudFlare also provides a number of speed optimization tools. On average, a website on CloudFlare:
- Loads twice as fast for its visitors
- Sees 65% fewer requests
- Saves 60% of bandwidth
This will most definitely vary from site to site, but overall those are pretty staggering statistics. You can calculate your specific speed benefits and savings using the CloudFlare analytics report within your account.
Built-in Content Delivery Network (CDN)
CloudFlare’s CDN reduces hops and lowers latency. On average, a request is fewer than 10 hops and takes less than 30ms. The result? Your website gains a global presence on an affordable budget.
Asynchronous Script Loading & Caching
The rocket loader service will automatically optimize your site to minimize the number of network connections to reduce the overhead of third party resources. This will speed up page rendering.
All web browsers work slightly different than one another, whether it is Internet Explorer, Firefox, Google Chrome, or Safari for iOS. Browser optimization automatically adjusts the way content is delivered based on the particular device accessing the site to maximize speed without affecting the site’s look or features.
GZIP is a compression process that reduces the size of a request by shrinking file sizes, similar to the way a ZIP archive does. Hardware optimized lossless compression reduces the size of all your resources and delivers them compressed, even through lazy firewalls that incorrectly claim browsers don’t support GZIP.
Local Storage Caching
Modern web browsers and mobile devices have the ability to intelligently cache the objects needed to render your site. CloudFlare automatically detects the users browser and enables these features to reduce website load time.
Cache Header Optimization
When you develop a website, there are certain instructions you can give to a web browser, telling it how long to store its temporary files. These settings are rarely used, but can have a large impact on the time it takes for a page to load.
This feature will automatically adjust the cache header instructions to allow browsers to correctly cache the resources of a site, and minimize the need for new requests.
Saved Bandwidth and Server Resources
Since CloudFlare acts at the domain level, before malicious requests hit the server, it effectively stops threats before they get to your website. This saves bandwidth and server resources. Your server is also freed up to serve your legitimate traffic optimally.
What is Cloudflare? Hopefully by now you that it’s a simple, effective way to protect your website or application from the countless attacks and threats that exist today. It will also ensure that your website is well protected in the future. Beyond security there are also significant performance and speed improvements. Hopefully you have a good understanding of how to make a website secure now.
