In a nutshell this is what Incapsula does:

Incapsula offers state-of-the-art security and performance to websites of all sizes. Through a simple DNS change, your website’s traffic is seamlessly routed through Incapsula’s globally-distributed network of high-powered servers. Incoming traffic is intelligently profiled in real-time, blocking even the latest web threats: from sophisticated SQL injection attacks to scrapers, malicious bots, intruding comment spammers and thwarting multi-Gigabit DDoS attacks. Meanwhile, outgoing traffic is accelerated and optimized with Incapsula’s global CDN, for faster load times, keeping welcome visitors speeding through.

I’ve always been interested in how to make my website faster but with the news about brute force attacks on WordPress, I wanted a more secure website as well. Researching WordPress security, I was surprised to find the following image from Incapsula on what sort of traffic you actually get.

So I decided to try Incapsula to see what it could do for my website and try and show you through this Incapsula review, just what this product can do.

But what can Incapsula do against all of this? A much easier way of answering this would be to watch their promo video

By using this plugin you will have no change to your originating IPs when using Incapsula. Incapsula acts as a reverse proxy and all incoming connections to your website first pass through one of Incapsula’s servers. This plugin will ensure that you continue to see the real originating IP of your website visitors.

Once this is all setup, it’s just a waiting game for Incapsula to start collecting the data.

Inside Incapsula

Once the DNS changes have been made and Incapsula has had time to do its job, you’ll see an image like above when you log in. This is a 7 day run down of what has been going on with your website. As you can see my bot visits out-number the human visits by quite some way.

Not all bots are bad however, I need Google-bot in order for my website to be found as well you a large number of other good bots but Incapsula reports that in the last 7 days there’s been 158 bad bots on my website!

Incapsula security

To test the security of Incapsula, I deleted my Askimet plugin as Incapsula can handle comment bots and protect me from spam. I also let it run for 7 days to see what it would report. Here’s my 7 day run down of what happened on my website.

Going further into the Incapsula dashboard you get a run down of the top attacking countries with USA being my top one with 30% next is China with 20%.

Incapsula also gives you a run down of the types of threats to your website.

So it’s clear that bots are my biggest problem and Incapsula also shows what type of bot is causing the most problems, in my case it’s the comment spammer with 94%. I did want to test just how good Incapsula was so I deleted my Askimet plugin. Considering the amount of comment spammer bots visting my websites, Incapsula does a very good job of protecting my website. Although I still get a couple of spam comments a day without Askimet, I’m still impressed with Incapsula.

Incapsula will also email you when there’s a threat. This is an email I got yesterday when someone tried to login to my website. Incapsula blocked the request.

This image is also provided by incapsula showing the top client applications. It surprising just how many bots are out there on the Internet!

To get a better idea of bot vs humans, Incapsula provides you with the following image. This is a nice example of just how much of your bandwidth is being wasted with unwanted bots on your website.

Incapsula speed

Not only does Incapsula do a pretty god job of protecting your website but it also increases the speed of it. By blocking unwanted bots and saving your bandwidth, it not only saves you resources and money but you also get to use their CDN for a faster website.

So I wanted to test the speed of Incapsula, I switched to advanced performance and tested the before and after. The results are below.

Before advanced

After advanced

According to Pingdom switching to advanced performance on Incapsula increased the speed of my website by just over 50%!

You can also see the response time of the CDN location centers.

With the advanced setting of Incapsula it also caches dynamic cotent which you can read about here. There’s also a good article on how a CDN can help your SEO by Incapsula.

I’ve been impressed with Incapsula, it not only protects me from spammers and bad bots but it has also increased the speed of my website by over 50%. I found Incapsula very easy to use and once the setup is done everything is done automatically for you leaving you with a peace of mind of a faster website with better security.

To ensure the success of our online trading operations, we place a major emphasis on state-of-the-art security, high availability (99.9% uptime) and user convenience.

Daily high-volume network DDoS attacks against our website were wreaking havoc with business operations, resulting in downtime for our online trading platform. The anti-DDoS solutions we had in place was not equipped to mitigate these attacks, which came precisely at the time when we were experiencing record trading volumes.

Since our company deals with a highly competitive and time-sensitive trading market, high availability and stability are paramount to building our users' confidence in our platform. It was obvious to us that in order to maintain and grow our business, we needed the best DDoS protection solution.

We required a high-capacity solution capable of mitigating the largest Layer 3 DDoS attacks, which can often reach several tens of Gbps. Blackholing was not a desirable option, since this aggressive method for diverting traffic actually serves the attackers' goal of denying and disrupting service by not allowing any visitors to reach the site.

To ensure an optimal user experience, we sought a DDoS mitigation solution that would be transparent to users. In this context, we preferred a solution that does not use delay pages, which cause problems for the application's APIs and prevent users from connecting to the server.

In terms of architecture, we preferred a cloud-based solution for reasons of cost-effectiveness and compatibility with our existing cloud computing infrastructure.

Aware of the threat to our core business, we immediately began to look for a new anti-DDoS solution with the network capacity and security proficiency to meet our requirements. After an in-depth evaluation of leading DDoS Protection services in several industry comparisons and reviews, we chose Incapsula's cloud-based DDoS Protection service based on its ability to mitigate any type of DDoS attack with virtually zero business disruption.

We conducted an initial trial with Incapsula while still experiencing DDoS attacks of up to 100 Gbps. Incapsula mitigated these attacks, keeping the online trading platforms up at all times.

Our experience so far shows that Incapsula is a marked improvement over other DDoS protection companies we have worked with in the past. Despite the fact that attacks on our high-profile website are still a daily occurrence, traders coming to the site are able to buy and sell without any noticeable degradation in terms of performance and availability.

Through its non-intrusive traffic filtering and an enterprise-grade Web Application Firewall, Incapsula has been stable in protecting our online applications. The service secures websites and applications against all types of DDoS attacks, as well as sophisticated application attacks such as XSS and SQL injections.

Incapsula is now a key component of our security infrastructure. When under DDoS, traffic is routed through Incapsula for screening, where malicious traffic and DDOS attacks are blocked automatically.

By using Incapsula's DDoS Protection, we have achieved concrete benefits:

• Cloud-based mitigation of network DDoS attacks - Incapsula mitigates high-volume network attacks through a global network of multi-gigabyte scrubbing centers
• Intelligent mitigation of sophisticated application layer attacks - Incapsula uses advanced traffic analysis algorithms, granular mitigation rules and an enterprise-grade WAF to differentiate legitimate website visitors (humans, search engines, etc.) from automated or malicious clients.
• "Always on" DDoS protection - Automatic "always on" DDoS mitigation and 24x7 monitoring are effective in stopping "hit & run" DDoS attacks can wreak havoc with solutions that need to be manually turned on and off on every burst.
• Dedicated SoC team – An experienced team of Security Operations Center (SOC) engineers performs 24x7 security monitoring and assists with DDoS mitigation as needed.

Incapsula helped us stay up during some of the biggest DDoS attacks on record. This happened at a critical business juncture, when our increasing trading volumes were turning us into the number one bitcoin trading site in the world. We hope to continue working with Incapsula as we gain more exposure and popularity.

Improvements to My Organization:

We use Incapsula for some of our sites and the experience has been excellent. You would not even know it was there – unlike those caching plugins (admittedly they are for speed not for security) – which remind you constantly that they are there so much so that you have to turn them off. Whoops.
