No issues.
What do I think about the stability of the solution?
No issues.
What do I think about the scalability of the solution?
No issues.
How are customer service and support?
Customer Service:
Once going enterprise, support is excellent.
Technical Support:Once going enterprise, support is excellent.
Which solution did I use previously and why did I switch?
CloudFlare and I switched because we needed more locations.
How was the initial setup?
Took us 10 minutes and we just waited for the DNS update.
What about the implementation team?
In house.
What was our ROI?
No ROI since we use it for protection. Its an additional expense with no ROI expectations.
What's my experience with pricing, setup cost, and licensing?
Always check the enterprise option, it gave us great rates.
Which other solutions did I evaluate?
We used CloudFlare in the past and we thought about working with Reblaze.

It has SSL support and content caching. You can 'play' with the rules as much as you'd like.
What is most valuable?
We are using Incapsula as our web application firewall and for DDoS protection, and it performs really well at its job. Incapsula packs some great features, such as SSL support, content caching and the ability to 'play' with the rules as much as you'd like.
How has it helped my organization?
Since this is the very first WAF solution that we evaluated and tried to integrate into our AWS environment, I can't really say that it has improved anything, but the fact is, we never looked the other way.
What needs improvement?
Incapsula has a built-in monitoring module, but it is a paid feature; I would expect that for the price we pay for the basic service, we would be able to integrate a monitoring solution, even a simple one.
In addition to that, Incapsula doesn't feature the option to add/remove available SSL protocols and/or ciphers.
For how long have I used the solution?
We have been using Incapsula for a little more than six months.
What was my experience with deployment of the solution?
The only problem we encountered with Incapsula regarding deployment is with their Performance solution that allows caching the hosted sites. The dynamic caching sometimes causes issues and we need to manually purge all of the cache from their system after a new version has been deployed, in order for new content to load properly.
How are customer service and technical support?
Technical support is excellent. In the few times we tried to contact Imperva's support, we received quick and swift replies.
Which solution did I use previously and why did I switch?
I did not previously use a different solution.
How was the initial setup?
The initial deployment is very straightforward; you follow a very simple setup wizard that guides you which changes you need to perform and where.
What about the implementation team?
We received the recommendation regarding Incapsula from Emind, a third-party vendor that helped us deploy our environment over at Amazon. The rest was performed by our in-house IT/Devops teams.
What other advice do I have?
I highly recommend Incapsula for anyone that is looking to integrate a WAF and DDoS protection into their environment.

IT Director at a tech services company with 51-200 employees
It can hide the true origin and provide access control. Their customer service sometimes has different responses for similar requests.
What is most valuable?
- Hidden origin
- IP whitelist
- Country blocking
- Anti-DDoS
- Special page protection (two-factor authentication)
How has it helped my organization?
For example, we host a website for customer in China. Incapsula can help to hide the real origin and provide access control over different pages. And it can protect the website from being attacked.
Incapsula provides 7x24 service for protection, which saves us a lot of manpower.
What needs improvement?
- Customer service: Their customer service sometimes has different responses for similar requests. We sometimes need to explain the issue many times before they understand. Their CS staff is not well trained according to a consistent standard. For the same requests, some of them can perform well, but some of them might do it wrong.
- Network management: Their network department sometimes doesn’t take the responsibility to improve network latency until we raise the problem many times or to top management. Sometimes, we encounter latency issues. Only sometimes does their network staff update their routing to improve the performance. Other times, they will not do so and they push the responsibility to another carrier.
For how long have I used the solution?
I have used it for one year.
What do I think about the stability of the solution?
Sometimes their system has routed our Asia traffic to US/EU and we needed to ask them to change the route back to Asia.
What do I think about the scalability of the solution?
Their Asia bandwidth, i.e. to China, sometimes has a lot of lag. And they take a long time to improve it, until they add a new ISP to improve the bandwidth.
How are customer service and technical support?
Technical support is 7/10.
Which solution did I use previously and why did I switch?
We previously used Akamai. Incapsula is much cheaper and the administration is much easier.
How was the initial setup?
Initial setup is easy, as Incapsula allows us to create new sites through their GUI or using an API.
What's my experience with pricing, setup cost, and licensing?
Incapsula pricing is very affordable.
Which other solutions did I evaluate?
Before choosing this product, I did not evaluate other options.
What other advice do I have?
If you don’t have a strong IT team for security, Incapsula is a good starting point for outsourcing your internet-facing security issues.

Installation requires just a CNAME entry, avoiding the risk of email downtime.
What is most valuable?
- Faultless inlining & minification: Every competing product breaks the layout, but we are yet to see Incapsula break a site
- Installation requires just a CNAME entry, avoiding the risk of email downtime.
- Instant PCI compliance and protection from the OWASP Top 10 vulnerabilities.
- CDN & DDoS protection.
How has it helped my organization?
Incapsula delivers a massive improvement to website performance and security in less than 20 minutes, regardless of the CMS. We love it so much that we decided to create a new service around this product, which could result in our largest income stream yet.
What needs improvement?
They once terminated a free account without warning, resulting in a few days downtime. But you get what you pay for.
For how long have I used the solution?
I have been using it for two years.
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 technical 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.

See the "valuable features" section above.
Systems Administrator at a financial services firm with 501-1,000 employees
Added security is the biggest bonus, as our websites have highly sensitive data.
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.
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.
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.
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.
