- DDoS protection
Sales Engineer/Major Accounts with 51-200 employees
With increasing traffic to our sites, it has protected them from DDoS attacks against which we did not previously have a solution.
What is most valuable?
How has it helped my organization?
Basically, before we found Incapsula, we were getting hit with 5-10 gigabit DDoS attacks, and we were trying to figure out how to fight the attacks. Therefore, we tried Incapsula out on one site, and through the trial we saw what the solution could do – the attacker gave up after a few tries. Once we signed up for an enterprise account with all ten sites we saw the attacks drop weekly.
What needs improvement?
It would be nice to get a feed from Incapsula to import into our system. We have to have multiple dashboards open at the same time, and it would be nice to have one single dashboard with all our information.
For how long have I used the solution?
I've used it for eight months.

851,823 professionals have used our research since 2012.
What was my experience with deployment of the solution?
No issues encountered.
What do I think about the stability of the solution?
No issues – it has been particularly stable.
What do I think about the scalability of the solution?
Scalability has been pretty good, our European traffic has doubled and our sales have gone up along with our stability.
How are customer service and support?
Customer Service:
10/10
Technical Support:10/10 – within 5 minutes we have had a response.
Which solution did I use previously and why did I switch?
We used a NetScaler mitigation appliance – nothing worked that well, we were getting attacks and they were taking down services.
How was the initial setup?
Setup was fairly straightforward. It took about 10 minutes as I had to fine tune it with our API to mitigate what traffic was being blocked. I was able to determine that pretty quickly and adjust accordingly.
What about the implementation team?
We did it in-house.
What was our ROI?
Probably about $150,00-$190,000 savings. It's hard to predict, but that would be my ROI estimate.
What's my experience with pricing, setup cost, and licensing?
It costs around $7/month, really cheap.
Which other solutions did I evaluate?
We looked at CloudFlare. We tried it but it didn’t work that well.
What other advice do I have?
Make sure you use a premium DNS provider. We had to move from a basic DNS provider to a more complex one to get it work with Incapsula 100%.

It provides intelligence on bad IPS and malicious software, and scales without issue.
What is most valuable?
- Human contact
- Fast SLA
- Trustworthy and excellent communication
Highly-functional back office with user friendly reports and intelligence on bad IPS and malicious software is at very high level and very quick. Part of the solutions function is that they have to stay on top of the data intelligence game. They have the first knowledge of break points.
How has it helped my organization?
The product makes information readily available and mitigates any problems quickly.
What needs improvement?
With the way that protection works, there is no such thing as pure protection, but as soon as Incapsula knows what a problem looks like, they fix it. They have to stay on top of the data intelligence game.
For how long have I used the solution?
I've used it for three years.
What was my experience with deployment of the solution?
It's usually fast but it can take two to three days on a big operation to get it live, especially if there is tracking.
What do I think about the scalability of the solution?
No problem with scalability.
How are customer service and technical support?
Customer Service:
Communication declined a bit as they got bigger – 7/10. Service is really good though.
Technical Support:8/10. Service is good.
Which solution did I use previously and why did I switch?
We went through at least a quarter million dollars in DDoS firewalls before we got to them. We tried solutions worldwide.
What's my experience with pricing, setup cost, and licensing?
For enterprise level stuff pricing is very competitive. Very good corporate deals.
What other advice do I have?
Go for it if you’re looking into it – they are a good solution and are trustworthy people. Just really works.

Online Marketing Manager with 1,001-5,000 employees
The user-generated spam stopped after we started using it to speed up and protect our website.
What is most valuable?
Their WAS - I had a problem and I turned to Incapsula. I needed someone to protect the website and they succeeded in this regard.
How has it helped my organization?
We’re not an e-commerce site, but a website for providing information, and we needed someone to protect the website. The user-generated spam stopped after we started using Incapsula, and so we feel more secure.
What needs improvement?
I needed some support and according to the SLA and I couldn’t get telephone support and it took a little while till they got back to me. We’re an enterprise company so I think I would be happier for a bit more support to pick the phone up and ask a question. There was not as much back office help as we would have liked.
For how long have I used the solution?
I’ve used it for four months.
What was my experience with deployment of the solution?
Yes, we had some down time but we solved it. It took us a few hours although we were promised no down time.
What do I think about the stability of the solution?
No issues with stability, but I still have to look into whether the site speed was faster than it was before as promised.
What do I think about the scalability of the solution?
No issues with scalability.
How are customer service and technical support?
Customer Service:
8/10 – very professional.
Technical Support:8/10 – very professional once they got back to me.
Which solution did I use previously and why did I switch?
I didn’t use any other solution.
What's my experience with pricing, setup cost, and licensing?
It’s not costly for my needs.
Which other solutions did I evaluate?
I knew the solutions available in the market because I was working in a cyber-security company. I suggested the product, because I knew the product and that they are better than other solutions for my needs.
What other advice do I have?
Do it on a Sunday in case there is down time. I would ask for support after implementation, and check that the site speed is as fast as it should be.

Stable and scalable with good account takeover protections
Pros and Cons
- "The solution has a very good interface."

What is our primary use case?
Primarily, clients are in need of some extra defense and a bit of protection, which is why they use this solution.
What is most valuable?
The most important aspect of the solution is the DDoS feature.
The solution has a very good interface.
Last year, the solution added a lot of additional improvements and functionalities, and for now, the features they have offered us have been great.
They recently added some account takeover protections that have been really useful.
What needs improvement?
The rules surrounding the making of web applications could be improved.
For how long have I used the solution?
I believe I've been using the solution for about four years.
What do I think about the stability of the solution?
There aren't issues with stability. As a cloud solution, it's hard to say if there will be stability issues. There might be issues with some customer setups, for example, but not with the product itself.
What do I think about the scalability of the solution?
The scalability of the solution is okay. Companies can expand it if they need to.
How are customer service and technical support?
We've been in touch with technical support in the past. Out of ten, I'd rate them at six or seven. We've had some issues with them in terms of response times, but overall they are okay.

We didn't previously work with a different solution. We've partnered with Imperva so we're dealing only with them.
How was the initial setup?
Typically, the initial setup is more or less straightforward. there isn't too much complexity.
What other advice do I have?
We're resellers of the solution.
Typically the solution is deployed with the help of DNS.
It's a good product. It's one of the best on the market. If a company can afford the solution, they should try it out.
I'd rate the solution eight out of ten.
Which deployment model are you using for this solution?
Public Cloud

What do I think about the scalability of the solution?
Nope; we have not encountered any scalability issues.
How are customer service and technical support?
Customer Service:
Some tickets seem to hang for some reason and some of the more-technical tickets seem to go through lot of different people before they get solved, but generally the customer service has been good.
Technical Support:General documentation is good enough that we haven't needed technical support that much, but the answers have been good once you go through the "Off-the-shelf" answers.
Which solution did I use previously and why did I switch?
We did try CloudFlare, but the pricing didn't suit our use case too well.
How was the initial setup?
The initial setup is fairly straightforward for a technical person.
What about the implementation team?
An in-house team implemented it all the way.
What was our ROI?
ROI is ~90%.
What's my experience with pricing, setup cost, and licensing?
Pricing is a good match for the features we use.
Which other solutions did I evaluate?
Before choosing this product, we also evaluated CloudFlare because it appeared first in Google.
What other advice do I have?
Basic setup is simple but, as with any caching/WAF setup, there are tricks you need to learn. But it works really nice out of the box!

Application Development Manager at a financial services firm with 501-1,000 employees
We're using it to replace Barracuda Web App Firewall which we retired several years ago.
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.

Support Manager at Sefisa
Reports are easy to configure with good graphics; tech support is knowledgeable
Pros and Cons
- "There are quite a few useful Imperva Incapsula features. For example, one of them is the reports. The graphics are very good and it's easy to configure. The whole process is very fast and reliable too. They have good tech support as well."
- "Users would benefit from better documentation. There is official documentation, but sometimes we need more detail. We have some use cases that are not so run of the mill. It would be great if there was a knowledge base that we could go to for more answers."
What is our primary use case?
Our customers have a number of use cases for Imperva Incapsula. Some use it to protect their APIs and others for its DDoS features.
What is most valuable?
There are quite a few useful Imperva Incapsula features. For example, one of them is the reports. The graphics are very good and it's easy to configure. The whole process is very fast and reliable too. They have good tech support as well.
What needs improvement?
Users would benefit from better documentation. There is official documentation, but sometimes we need more detail. We have some use cases that are not so run of the mill. It would be great if there was a knowledge base that we could go to for more answers.
The price could also be more reasonable. The price should at the very least be adjusted for different parts of the world. For example, here in Latin America, our budgets are very different than those for projects in the United States or Europe. It would be really positive if we could get the product at a more affordable price as we are customers with lower budgets without sacrificing features or capabilities of the solution.
For how long have I used the solution?
I have been using Imperva Incapsula for about three years. It's a solutions I recommend to my customers.
What do I think about the stability of the solution?
This is a very stable solution.
How are customer service and support?
I like their support. The times we have asked for their help, they have been very accurate at giving answers.
How was the initial setup?
The initial setup is easy. It can take maybe half an hour due to the propagation of the DNS name on the server. However, setting up one Imperva website is very easy. You just have to wait for the DNS to refresh on the other DNS server and that's it.
What other advice do I have?
I would encourage people to implement Imperva Incapsula. I think it is a very mature, easy to use, and reliable solution.
