Scalable and stable firewall for web applications with a good interface, but path and traffic visibility need improvement
Pros and Cons
- "Very scalable and very stable firewall for web applications, with a good interface in its cloud version. Mitigation is its most valuable feature. The technical support for this product is also good."
- "Imperva Web Application Firewall is a good system, but we found that the visibility of the diverse-path server, e.g. where the traffic is coming from, the different IPs, etc., needs improvement."
What is most valuable?
What needs improvement?
Every product has a room for improvement, and in Imperva Web Application Firewall, we found a limitation when we need to check which email IP traffic is coming from, e.g. we cannot find it.
Imperva Web Application Firewall is a good system, but we found that the visibility of the diverse-path server, e.g. where the traffic is coming from, the different IPs, etc., needs improvement. If we can populate those information, we can block them in our firewalls, and that would make this solution better.
Though the cloud interface of Imperva Web Application Firewall is good, the interface of the on-premises version is not as appealing, and it's what I'd like to see improved in the next release of this solution.
What do I think about the stability of the solution?
Imperva Web Application Firewall is a very stable solution.
What do I think about the scalability of the solution?
The cloud version of Imperva Web Application Firewall is very scalable.

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.

Director at IT Big Bang
Easy to use and enables us to put everything in code
Pros and Cons
- "Simplifies putting everything in code."
- "A limited tool if you're looking to customize."
What is our primary use case?
The company uses this solution to protect us from any potential attacks. We are customers of Imperva and I'm the company director.
What is most valuable?
Imperva makes it easier for us to put everything in code; we use Terraform to deploy our infrastructure.
What needs improvement?
This is a very limited tool if you're looking to customize. It would be helpful if Imperva would provide additional resources for Terraform that can easily be deployed. There are some cases where we're currently unable to use Terraform.
For how long have I used the solution?
I've been using this solution for six months.
What do I think about the stability of the solution?
The solution is stable although sometimes content delivery seems to be affected because it's in the cloud.
What do I think about the scalability of the solution?
Scalability is fine and we haven't had any issues with resource consumption.
How are customer service and technical support?
Technical support is quite proactive in sharing information.
How was the initial setup?
The initial setup is relatively straightforward.
What other advice do I have?
I rate this solution eight out of 10.
Which deployment model are you using for this solution?
Public Cloud

Simple to maintain, easy to configure, and easy to scale
Pros and Cons
- "It has fewer false positives"
- "The support for the on-premises version needs improvement."
What is our primary use case?
I am a distributor for Imperva. We provide solutions for our customers.
This solution is mainly used to protect websites. When it is deployed on the cloud it is used for traffic redirection and URL redirection functionality.
It is also used for dual location blocking and security for the policies that are being applied.
What is most valuable?
Imperva is a good solution.
It has fewer false positives. It is very simple to maintain the device. It is also simple to configure. You don't need to have any HTTP knowledge or understand the HTTP programming languages when it comes to configuring the device.
What needs improvement?
The visibility of the actual traffic needs to be improved.
We are only monitoring the traffic if there are any issues and the alerts are being triggered.
We don't log the real-time traffic. We only log the real-time attacks and not the normal traffic that is passing through the device.
The main concern for our customers is to improve the visibility of the actual traffic. Customers feel that is the one feature that will greatly improve Imperva.
They would like to have the complete network traffic passing through the device. Currently, we are only being alerted for the attack that has passed through the device instead of the genuine traffic.
We would like to see logs of the genuine traffic that passes through the device. It can be optional to enable it for certain customers and certain applications but should be included.
The support for the on-premises version needs improvement.
For how long have I used the solution?
We have been distributing Imperva for the last 10 years.
We are currently dealing with the latest version.
We provide both on-premises and cloud deployment, it depends on the customer's requirement.
What do I think about the stability of the solution?
Once it is configured it is stable. There are no issues with the stability of the Imperva Web Application Firewall.
What do I think about the scalability of the solution?
It is easy to scale. The scalability is fine. You can add gateways and scale, which is a good feature in Imperva.
This device is suitable for everyone.
How are customer service and technical support?
There are two different support teams. The cloud support is very good, but the on-premises support is lacking. The response time could be much better.
How was the initial setup?
The initial setup is easy if you know how to deploy Imperva. Once we do the base installation, the deployment is simple.
Once in six months, there are some patch upgrades required. If there are specific requirements we need to upgrade.
What about the implementation team?
We were able to complete the installation and deployment ourselves.
What's my experience with pricing, setup cost, and licensing?
When it comes to the cost, there are different sets of customers. Some are SMB and veteran customers who go with the cloud version of Imperva, which is a managed service. The next-level customers and enterprise will select the on-premises version along with the cloud. They prefer the hybrid environment.
There are a couple of different licensing models. One is with respect to the Cloud and is based on the number of applications you have to protect. The on-premises model is based on the throughput that is required to be inspected.
Which other solutions did I evaluate?
I know that FortiGate is a niche product and wanted to evaluate Impera and FortiGate for the differences.
What other advice do I have?
You should understand the customer's website, what their website is. They need to configure the ciphers properly. Many engineers are not able to complete the project because they don't understand the customer's environment.
Before doing an implementation, understand the customer's environment. The ciphers need to be configured properly. Some Imperva engineers are not able to complete the projects because they understand the customer's environment.
Know the ciphers being used and match the ciphers. You must ensure the same ciphers are being matched in the backend load balances. If the backend load or cipher is changed the same should be replicated in Imperva as well. Once this is complete it should be good.
I would rate this solution an eight out of ten.

Easy to deploy with good cost savings and great scaling potential
Pros and Cons
- "The solution is stable."
- "I loved the approach of the cloud. The cloud has a lot of new features, like advanced web protection and DDoS protection. If those could also be on-boarded onto the on-prem versions, that would be ideal. They need to pay attention to both deployment options and not just favor one."
What is most valuable?
The product is very good.
It's so easy to do the deployment. The installation is very straightforward. You can't even compare it to others on the market. It's that easy.
The features on offer are very nice.
The solution is stable.
The licensing setup makes the product easy to scale.
The pricing is very good.
What needs improvement?
I loved the approach of the cloud. The cloud has a lot of new features, like advanced web protection and DDoS protection. If those could also be on-boarded onto the on-prem versions, that would be ideal. They need to pay attention to both deployment options and not just favor one.
For how long have I used the solution?
I've been using the solution for the last five years. I've used it for quite a while now.
What do I think about the stability of the solution?
The stability of the product is good. There are no bugs or glitches. It doesn't crash or freeze. It's reliable.
What do I think about the scalability of the solution?
We typically deal with medium-sized organizations.
The licensing model makes the solution very simple to scale. If a company wants to expand, it's not a problem.
How are customer service and technical support?
We need an improvement in the support. We need a lot of turnarounds. Whenever is a ticket open, it's something that has become a concern.
Which solution did I use previously and why did I switch?
I'm not currently working with any other solution. I just use this product.
Previously, I did work with F5 and Fortinet. However, Imperva is superior to both of these products.
How was the initial setup?
The initial setup is easy and the solution is very simple to deploy.
What's my experience with pricing, setup cost, and licensing?
The solution is very affordable and the cloud is making it even easier in terms of cost savings.
What other advice do I have?
We are resellers and we are based in Kenya. We're actually doing the whole suite. I'm working with Database Security and I'm also doing the Web Application Firewall, both of which are on-prem and on the cloud. I'm also doing the DRA.
It's the best in breed in terms of a solution you can put in place.
I'd rate the solution at an nine out of ten. We're quite happy with its overall capabilities.
Which deployment model are you using for this solution?

Straightforward to set up with good technical support and stability
Pros and Cons
- "The solution can scale."
- "In the past, I have bugs on the WAF. I've contacted Imperva about them. Future releases should be less buggy."
What is our primary use case?
My experience is to integrate this application. It's a firewall. You must connect it with the traffic the infrastructure must be routed through this firewall in order to block and search for any problems with the applications.
What is most valuable?
As a system, it's very effective at blocking potentially malicious items. The security is very good.
The solution can scale.
The stability has been pretty good.
Technical support is helpful.
The initial setup is rather straightforward.
What needs improvement?
In the past, I have bugs on the WAF. I've contacted Imperva about them. Future releases should be less buggy.
For how long have I used the solution?
I've been working with the solution for about three years or so.
What do I think about the stability of the solution?
I have previously found bugs within the solution and in the past, I have contacted Imperva in order to deal with them to get them resolved.
That said, for the most part, I have found the solution to be quite stable. It doesn't crash or freeze. It works well.
What do I think about the scalability of the solution?
The solution can scale.
We typically deal with medium-sized enterprises as clients. Typically, these companies have around 500,000 or so employees. They aren't massive, however, they are quite sizeable.
How are customer service and technical support?
I've dealt with technical support on multiple occasions and I find them to be very helpful and responsive. They are knowledgeable. We're very happy with the level of service we get.
How was the initial setup?
The initial setup is straightforward, although it does take time to integrate the solution into your existing infrastructure.
What about the implementation team?
As an integrator, I can help clients set up the solution at their companies.
What's my experience with pricing, setup cost, and licensing?
I'm not sure what the exact licensing costs are for the solution. I can't speak to the pricing. It's not part of my responsibilities to cover sales or billing.
What other advice do I have?
Imperva has different three parts - the Web Application Firewall (WAF), Incapsula for cloud, and DAM for database firewalls. This is in one central monitor.
We aren't using the latest version of the solution.
We use the solution as a customer as well as an integrator.
I'd rate the solution at a ten out of ten. It's very good. We've been quite happy with its overall capabilities.

Stable, protects well against a variety of attacks, especially DDoS
Pros and Cons
- "The solution has been quite stable. I have not seen any bugs at all."
- "Sometimes our web application firewall will slow down."
What is our primary use case?
We primarily use the solution for database security.
Basically, the solution is a web application firewall that is used to protect against multiple types of attacks online. It is used for web attacks - mostly DDoS attacks, cross-site scripting attacks, or SQL injection attacks.
There is also multiple HTTP protocol compliance. If there is any violation it will be detected by this application. It is used for detecting an illegal file type, illegal URL, or bots.
The solution can prevent a geolocation attack also. If any application is not allowed from certain countries, it will not allow access. We can detect everything via the web application firewall.
What is most valuable?
The solution offers good security against a variety of web attacks.
The protection from DDoS attacks is very useful. The DDoS attack is a very powerful attack that can harm a company's services. If an application is deployed to any web server or database our service will slow and will go down. A user would not be able to access our service until we can fix the issue. It's a deal if a company can avoid getting hit with DDoS attacks and having something that can effectively protect a company is extremely useful.
The solution has been quite stable. I have not seen any bugs at all.
What needs improvement?
Until now, it is good. There are no issues. As an analyst, I simply monitor. I don't really get too far into the technical aspects of the solution.
Occasionally, I've noticed that the web application firewall was down. If we are not using proper storage, proper memory, proper CPU, and if multiple attacks happen at one time, they will be detected by our web application firewall. Sometimes our web application firewall will slow down. In that sense, it needs some improvement. We do have a precaution for if the solution goes down. We basically, need to increase the memory and the storage and the CPU utilization, so that we can prevent our company from malicious activity.
I cannot say which type of memory or storage should be improved. The requirements depend on the organization. What organizations need and which type of configurations would work best as per their requirements depend completely on that.
For how long have I used the solution?
I've been working with the solution for about three years or so. It's been a while. I've been mostly working with it over the last 12 months or so.
What do I think about the stability of the solution?
The solution is quite stable. There are no bugs or glitches - or at least, I haven't seen any problems on that front. It doesn't crash or freeze. It's reliable.
What do I think about the scalability of the solution?
Right now, it depends on the company and its needs. I can't speak to if there are plans to increase usage.
How are customer service and technical support?
I've never been in touch with technical support. I can't speak to how knowledgeable and responsive they are, having never communicated with them directly. As an analyst, it's not my responsibility to deal with technical issues directly.
Which solution did I use previously and why did I switch?
It's my understanding that this company has only used this solution. However, if I move somewhere else, it's possible that something else may be used.
How was the initial setup?
I wasn't part of the initial setup. I can't speak to how easy or difficult the process was.
What's my experience with pricing, setup cost, and licensing?
I am not sure of the exact licensing costs of the solution. The licensing is a management decision. The costs and payments are handled by them.
What other advice do I have?
We use the solution's latest version.
We have a partnership with Imperva within our company.
I'd rate the solution at a nine out of ten. We've been mostly quite happy with its capabilities.
