884,873 professionals have used our research since 2012.
What do I think about the stability of the solution?
I have not encountered any stability issues.
What do I think about the scalability of the solution?
I have not encountered any scalability issues.
How are customer service and support?
Technical support is first class. These guys are sharp.
Which solution did I use previously and why did I switch?
We moved from CloudFlare because Incapsula’s minification was faultless, and their CNAME installation procedure avoided downtime for other services such as email.
How was the initial setup?
It was very easy to set up: 20 minutes and you're done.
What's my experience with pricing, setup cost, and licensing?
Go for the $59/month Pro plan. Free accounts can get terminated, and the higher plans are only if you like to have your own SSL certificate, or get regular DDoS attacks. The Pro plan has everything you need; it's just that you're using Imperva's SSL certificate, not yours.
Which other solutions did I evaluate?
Before choosing this product, we evaluate other options in great detail. We looked at CloudFlare, W3 Total Cache, WP Super Cache, Wordfence, BulletProof Security, Varnish, Mod_Security, ConfigServer, and a variety of other options. Incapsula isn't the cheapest, but is way in front of the competition. You'll easily spend double/triple the cost of your Incapsula subscription on maintaining any other solution, whereas Incapsula handles all that overhead for you, right out of the box.
What other advice do I have?
Don't wait till you've been hacked; get protected now. It'll cost you at least a year of Incapsula fees to recover from website hacking. And if your website is running slow, Google is probably already penalising your site, when the fix is so easy. Incapsula is by far the fastest fix for both website speed and security.

Added security is the biggest bonus, as our websites have highly sensitive data.
Pros and Cons
- "Keep your sites strongly secured but sleep easier knowing Imperva Incapsula continuously baffles our penetration testers."
- "The API is lackluster but especially for customers."
Valuable Features
The added security is the biggest bonus feature, as our websites are not usually under extreme load but do have highly sensitive data. A good WAF can be difficult enough to configure even without many of the advanced security features that Imperva Incapsula includes: SQL injection prevention, bot attack recognition and notification, and DDoS.
Improvements to My Organization
Our audit experience is made much more simple due to having this solution. It is an answer to many security issues. We have all of the same sites available and audited internally. This extra layer of security helps with the external 'monitoring and alerting' and keeps that heavy administration portion to those who can handle it at scale a lot easier.
Room for Improvement
The API is lackluster but especially for 'customers'. The only thing we wanted to use the API for was only available to resellers.
Use of Solution
I have been using it for 5+ years.
Stability Issues
I have not encountered any stability issues at all.
Scalability Issues
We have a multitude of DNS names for essentially the same site. Despite that, we have to pay for each of these separately as different sites. This model is unfortunate for us but we find the service to be worth it. I could see this being a potential issue, while it is not yet.
Customer Service and Technical Support
I have had to contact support only once for API support and it was a good experience.
Initial Setup
Initial setup was simple but admittedly handled by a different person. I have set up and decommissioned sites with ease.
Pricing, Setup Cost and Licensing
You get a better bang for your buck with converged DNS site names. If you use separate DNS for smaller portions of a site, it will increase your licensing cost.
Other Solutions Considered
Before choosing this product, I did not evaluate other options.
Other Advice
Keep your sites strongly secured but sleep easier knowing Imperva Incapsula continuously baffles our penetration testers.

Its DDoS Protection and Load Balancing helped maximize our security by adding an extra layer of protection.
Pros and Cons
- "Incapsula’s DDoS Protection and Load Balancing really helped maximize our security."
Valuable Features:
- DDoS Protection
- Load Balancing
Improvements to My Organization:
Incapsula’s DDoS Protection and Load Balancing really helped maximize our security. It added an extra layer of protection.
Threat monitoring allows us to save time when responding to an incident. Previously we would have had to analyze logs, generate reports which takes time that could be spend remediating issues. Incapsula gives an uncomplicated overview of what is happening among other things.
Incapsula's DDoS protection service delivers immediate and comprehensive protection for both network and application level (Layer 7). DDoS is a hugely beneficial feature.

It helped us investigate and narrow down possible attacks from suspicious IPs.
Pros and Cons
- "We're able to better manage network traffic with its analysis and security tools."
- "Its firewall should be made less penetrable so that if an IP is blocked once, it doesn't penetrate again."
Valuable Features:
- It provides real-time traffic analysis.
- It gives location/hit/page view details.
- It can easily and instantly block IPs.
- We can investigate questionable and suspicious IPs.
Improvements to My Organization:
We're able to better manage network traffic with its analysis and security tools.
It also helped us investigate and narrow down possible attacks from thousands of hits from suspicious IPs. In so doing, it also noted the presence of background scripts.
It's helped us find vulnerabilities in our organization.
Room for Improvement:
- Its firewall should be made less penetrable so that if an IP is blocked once, it doesn't penetrate again.
- The IP analytics should show trends and potential problem areas so that We can take action to minimize the occurrence of more hits from malicious IPs.
- The process of reporting, analysis, and clearance could be improved.

It's improved the speed of our website and setup is straightforward, although the file-purging function could be improved.
Pros and Cons
- "The website itself is our first priority and we have seen improvements in that area -- it's faster."
- "Although we're only using it for the accelerator part, the purging of files and the way this feature functions could use improvement."
What is most valuable?
- CDN
- Site performance
How has it helped my organization?
The website itself is our first priority and we have seen improvements in that area -- it's faster.
What needs improvement?
Although we're only using it for the accelerator part, the purging of files and the way this feature functions could use improvement. It requires the user to either purge everything or go through specific files, but if you do, the latter doesn’t always work. So with the single files sometimes there is more difficulty.
For how long have I used the solution?
I've used it for a few months now.
What was my experience with deployment of the solution?
No issues. It was very straightforward.
What do I think about the stability of the solution?
No issues.
What do I think about the scalability of the solution?
It meets our needs right now. In the following months we are well within our package, but in the long term, we have to see if the cost will go up too much for our project’s needs. We are well covered for now.
How are customer service and technical support?
Customer Service:
9.5 -- they're very good.
Technical Support:9.5 -- turnaround is very fast.
Which solution did I use previously and why did I switch?
No, as we are a fairly new project so we have no other experience with another solution. However, we did look at CloudFlare, Limelight, and CDN networks.
I had a gut feeling about the product right from the get-go.
How was the initial setup?
Very straightforward setup.
What about the implementation team?
It really depends what you're looking for. If you need to have a straightforward CDN, this CDN would probably be too expensive. If you want one solution with an all-in-one package for CDN and acceleration, I would definitely recommend Incapsula.

We were able to dial in the security and protection that it provided and understand the threat to our company website.
I was introduced to Incapsula after our company website had started to show signs of a persistent active DDoS attack.
I got on the phone with their representative, who later brought in an engineer and within that same day we were able to begin mitigating the problem, all under the free trial. We were able to easily dial in the security and protection that the service provided and began to understand the threat (which was not a DDoS attack) quickly.
We were so impressed with the effectiveness of the solution and the assistance that we received from support that we subscribed to their service in an ongoing basis, which has proven to be reliable and simple to use.
However, I'd like to be able to drill down more into the analytics that Incapsula collects. For example, I'd like to be able to click on the pieces of the pie charts to get more detailed info. also, we had a small issue with some vagueness in the installation instructions, but we sorted it out and everything was good from that point on.
They helped us to get the solution up and running, as well as assisted in setting up rules and other security settings that improved the overall effectiveness of the solution. I would recommend Incapsula's solution to anyone looking to add a robust security layer to their web sites and properties.

The Web Application Firewall is helpful in protecting SQL injections.
Pros and Cons
- "This implementation helped our organization a lot in handling web attacks by hackers and other malicious intruders."
Valuable Features:
The Web Application Firewall (WAF) is very helpful in protecting SQL injections by hackers.
Improvements to My Organization:
We implemented the WAF feature of Incapsula in our application which was exposed to the public.
This implementation helped our organization a lot in handling web attacks by hackers and other malicious intruders.
Room for Improvement:
There is nothing as of now that I could suggest.
Deployment Issues:
We faced a bit of difficulty during setup, but the issue was resolved easily.
Cost and Licensing Advice:
I don't know because licensing is handled by PIR infrastructure and software team.
We have just been provided a license to use the product.
Other Advice:
You can safely implement it irrespective of your application usage size.

We're using it to replace Barracuda Web App Firewall which we retired several years ago.
Pros and Cons
- "I would say compare it to other solutions in the marketplace feature by feature and see how Incapsula reporting and analytics dashboards compare and bot control compares – their solution for bot control is pretty good – and check those features with other enterprise level solutions, you get a lot for your money."
- "The interface seems a bit outdated and simplistic."
What is most valuable?
I'd say that the most valuable feature is the ease of use in configuration, the analytics, and the integration with Incapsula’s robot database.
How has it helped my organization?
The product should be able to protect us from illegitimate web traffic, and reduce our data center costs through lowering the load on our systems.
What needs improvement?
The interface seems a bit outdated and simplistic.
For how long have I used the solution?
I have been familiar with it for a few months now.
What was my experience with deployment of the solution?
No issues with deployment.
What do I think about the stability of the solution?
No issues with stability.
What do I think about the scalability of the solution?
No issues with scalability thus far; we haven’t tried yet.
How are customer service and technical support?
Customer Service:
Fairly low – I’m in between Incapsula sales people so it’s hard to answer, but I have had trouble getting answers to my questions.
I like the product so I am happy with that but getting to them was not simple.
Technical Support:They had one thing they had to do and they did that – was pretty straightforward.
Which solution did I use previously and why did I switch?
Yes, we were using Barracuda Web App Firewall which we retired several years ago.
How was the initial setup?
It was straightforward.
What about the implementation team?
I implemented on my own.
What's my experience with pricing, setup cost, and licensing?
Per month, the cost varies between $200 to $2,000, and there's no initial setup cost.
What other advice do I have?
I would say compare it to other solutions in the marketplace feature by feature and see how Incapsula reporting and analytics dashboards compare and bot control compares – their solution for bot control is pretty good – and check those features with other enterprise level solutions, you get a lot for your money.
