June 2025

Learn what your peers think about Imperva Web Application Firewall. Get advice and tips from experienced pros sharing their opinions. Updated: June 2025.
856,873 professionals have used our research since 2012.
What do I think about the stability of the solution?
Imperva solutions are the best in terms of stability.
What do I think about the scalability of the solution?
I have not faced any trouble with scalability because you can easily upgrade the appliance.
How are customer service and support?
I am regularly in contact with Imperva support and I am satisfied with them.
How was the initial setup?
The initial setup is very basic and really easy to do. I wouldn't say that everybody, such as non-technical, people can do the setup and configuration. However, people with a mid-level of experience in application firewalls can do it easily.
What's my experience with pricing, setup cost, and licensing?
The price of this solution is a little bit high compared to competitors.
What other advice do I have?
My advice to anybody who is considering this solution is that if they want a stable product with good scalability then they can choose Imperva. The price is a little bit higher than that of the competitors, which largely impacts whether customers choose Imperva. In fact, if you don't care about budget then Imperva is the only solution for an application firewall.
My only complaint is that the user interface could be better.
I would rate this solution a nine out of ten.
Which deployment model are you using for this solution?
On-premises

CTO at CyberApp
Dual perspective of positive and negative security makes for optimal protection
Pros and Cons
- "Compared to other web application firewalls in the market, Imperva does things in the most accurate way."
- "I think that better bot protection is needed in this solution."
What is our primary use case?
For some time now, I have been the CTO of a consulting company and our main issue is web application security. We also handle database security.
This is one of the solutions that we implement for our clients.
The primary use of this solution is the protection of applications.
What is most valuable?
This product has a logical perspective of negative and positive security. Negative meaning all of the blacklisted websites, and the positive is the profiling of the website itself. Impera can see and activate the policy, based on what it has learned. Imperva learns things like how dynamic content is dealt with, and what the permitted values are. When you combine these two perspectives, the negative and the positive, you get the optimal protection of the application.
What needs improvement?
When you want to move to a higher version of the platform, it is not in the GUI and not very easy to do. I expect that this will be available in the next version.
I think that better bot protection is needed in this solution. Bot protection is one of the features in Imperva that lets you recognize if their request is coming from a human or coming from a bot. In this context, a bot is a mechanism being used by the attacker. Good bot protection will reduce a lot of the attacks coming into the applications.
For how long have I used the solution?
I have been using this solution for about eight years.
What do I think about the stability of the solution?
This solution is pretty stable.
What do I think about the scalability of the solution?
If you build this solution properly then you have scalability.
How are customer service and technical support?
We do not use technical support very often. It is only in cases where we get something that looks like a bug. Their team is good.
How was the initial setup?
The initial setup of this solution is user-friendly and pretty straightforward.
However, the setup, in order to bring the application into inspection, is kind of complex. You need to know what you're doing. It takes approximately four hours to install, setup, and configure this platform.
What about the implementation team?
My team and I handle the integration of this solution for our clients.
The number of people required depends on the environment. Sometimes it is one person, whereas other times there are two.
We have three people who take care of maintaining this solution for our customers.
What's my experience with pricing, setup cost, and licensing?
The cost of this solution depends on the platform. For example, you may be buying virtual or you may be buying appliances. It also depends on the number of environments and the bandwidth that is required.
Which other solutions did I evaluate?
Compared to other web application firewalls in the market, Imperva does things in the most accurate way.
What other advice do I have?
Overall, Imperva is a pretty good product.
I am working with the development team for Imperva in Israel, and I have submitted some feature requests for things that I think should be changed. Everything that should be fixed, we have a discussion on it and it is probable that these things will be fixed.
My advice to anybody who is implementing this solution is to first go and learn the attack surfaces because you need to protect the assets from attack. In order to do this, you need to understand the attacks. Let's say that a good defense is a good offense.
The biggest lesson that I have learned from working with this solution is to back up the system all of the time. Do it step by step, and be very precise. Have plans for each and every move, all of the time.
I would rate this solution a nine out of ten.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.

Head of IT at a computer software company with 11-50 employees
A solution with great dynamic profiling, good technical support, and a straightforward setup
Pros and Cons
- "The dynamic profiling of websites is the solution's most valuable feature. The security is also good."
- "It would be useful if the solution used more intelligence in attack protection. For example, firewalls are to be dependent on the configuration, but if they could have some data science around it the solution would be even better. The profiling of the traffic, and making decisions surrounding that should be intelligence-based, instead of being based on the configuration of the firewall itself."
What is most valuable?
The dynamic profiling of websites is the solution's most valuable feature. The security is also good.
What needs improvement?
It would be useful if the solution used more intelligence in attack protection. For example, firewalls are to be dependent on the configuration, but if they could have some data science around it the solution would be even better. The profiling of the traffic, and making decisions surrounding that should be intelligence-based, instead of being based on the configuration of the firewall itself.
For how long have I used the solution?
I've been using the solution for two to three years.
What do I think about the scalability of the solution?
The solution is scalable, however, in terms of scalability, you're required to change the appliance, as it's not like a cloud, which is easier to scale. I would not rate it very well when it comes to scalability, because a model of license-based upgrades would be better. They could give you a bigger box to make it easier to grow if you needed to.
How are customer service and technical support?
The solution's technical support is good.
How was the initial setup?
The initial setup is straightforward. However, when you move to more advanced configurations, you require more expertise.
What other advice do I have?
We are an integration company, so we are providing this as a solution to other customers. They're mostly enterprise-level clients.
I would recommend the solution. I'd rate it eight out of ten.

Chief Information Security Consultant at V-Tech
Has good monitoring and you get what you expect from this solution
Pros and Cons
- "Data masking is the most valuable feature of this solution."
- "Some of the features should be included in the next release is a file integrating monitoring tool. This feature should be improved."
What is most valuable?
Data masking is the most valuable feature of this solution.
What needs improvement?
Most of the clients are new to this solution and don't have an in-depth knowledge of the solution. It's not so well-known in Ethiopia. Imperva has only been around for a year.
Licensing should be improved. Most of the clients aren't happy. It's expensive.
Some of the features should be included in the next release is a file integrating monitoring tool. This feature should be improved. Also, it should have a privileged account option. In the solution, if you put it there, that would be a very nice feature so that the clients could get all those solutions in one box. It will be easier for support and for clients.
For how long have I used the solution?
I have been using Imperva for the last two to three years.
What do I think about the stability of the solution?
It's a relatively new product but from the information I got from the Bank of Ethiopia, the stability is okay. They are getting what they are expecting from the product.
What do I think about the scalability of the solution?
Scalability is good especially compared to IBM. It's not so easy to integrate with another solution from another vendor.
How was the initial setup?
The initial setup was complex.
What other advice do I have?
The company has to deeply work on it. Also, with regard to support for the distributor, distributors have a big problem. We got the wrong consigning. It was kept for more than three months in a customs warehouse because of the issue of the problems on the distributor side. That is a big problem.
I would rate it an eight out of ten. Imperva is good because it doesn't also only monitor but it also does acquisition.

Cloud Solutions Architect at Snapnet Limited
A highly scalable solution with good stability and great data marking capabilities
Pros and Cons
- "The solution is very scalable. It is one of the most important features. You can also expand resources and features as well."
- "The initial setup could be simplified. Every time you have to install the solution you have to get in touch with support or somebody that can to do that for you."
What is most valuable?
Data marking is the solution's most valuable feature.
What needs improvement?
The firewall aspect of the solution needs improvement.
The GUI is not as intuitive enough. It should be more user-friendly, especially for end-users.
The initial setup could be simplified. Every time you have to install the solution you have to get in touch with support or somebody that can to do that for you.
For how long have I used the solution?
I've been using the solution for a year or two.
What do I think about the stability of the solution?
The core functionality of the solution has been met. We find it stable enough.
What do I think about the scalability of the solution?
The solution is very scalable. It is one of the most important features. You can also expand resources and features as well.
How are customer service and technical support?
Customers actually require a lot of support. They want an easier channel that can provide support. The solution should offer a monthly check-in with clients. Other solutions offer this, and it's helpful for the clients, just to make sure everything is running okay.
In general, however, technical support has been good.
How was the initial setup?
The initial setup required a lot of help. It took a month or two to deploy so it wasn't exactly straightforward. However, it was not as difficult as other solutions either.
What other advice do I have?
I handle the on-premises deployment model. We have the latest version of the solution. We also sell the product.
I would rate the solution nine out of ten.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.
Solutions Architect at a tech services company with 51-200 employees
Useful out-of-the-box threat protection, not too complex, and has good technical support
Pros and Cons
- "There are some features that are configured by default, so even without doing much, it can still provide a level of protection."
- "It would be helpful to have a "recommended deployment", or even a list of basic features that should either be used or turned on by default."
What is our primary use case?
This is one of the solutions that we provide to our customers.
We use this solution for application-level security, above layer four protection where the firewall cannot reach.
I have worked with both on-premises and cloud deployments.
What is most valuable?
The most valuable feature is the out-of-the-box detection engine. It has the ability to detect some of these things without being configured. There are some features that are configured by default, so even without doing much, it can still provide a level of protection.
What needs improvement?
The visibility provided by this solution can be improved. I often tell my customers that "You can't fight what you can't see". I can recall a time when I did a presentation after a deployment, and it prompted them to put the solution into enforcement mode immediately. Normally, we wait one week with the solution in monitoring mode. However, once they saw the types of vulnerabilities they had, they wanted to take action right away. It gave them a great deal of knowledge, and knowing that they are protected from these types of attacks has boosted their confidence.
This solution has a lot of features, and some of the students were confused when I was discussing them. It would be helpful to have a "recommended deployment", or even a list of basic features that should either be used or turned on by default. If somebody has installed the product several times but is doing the same thing incorrectly, then they get experienced in doing the wrong thing. You should be able to specify which assets you need to be protected, and the solution will tell you the minimum in terms of features that need to be turned on. If you need more advanced protection then the others will become relevant.
Imperva partner training is something that I would be interested in if it ever came my way. There should be partner-specific webinars, meetings, and other training provided to us,
For how long have I used the solution?
I have been using this solution for about two years.
What do I think about the stability of the solution?
So far, I don't think that we've had any issues with this solution in terms of stability. People discussing this solution have given the same remark.
This solution is used on almost a daily basis.
What do I think about the scalability of the solution?
Scalability of this solution is based on the design. If you get your design right, then you shouldn't have a problem with the scalability.
How are customer service and technical support?
While we were installing this solution, we had contact with technical support and they were good. I have referenced information that is on their site and it is helpful, as well.
During the initial installation, there was a warning that was not part of the known CVEs. When I checked with support, they told me that this type of problem is blocked out-of-the-box. However, if I wanted to be really sure, they showed me how to create a custom policy, or custom rule, to specifically deal with it.
Which solution did I use previously and why did I switch?
I have used other solutions, but I usually follow the Gartner reports and their suggestions. My previous solution had not been doing too well.
Also, as I became more familiar with this solution, it became easier for me to identify issues. I had also read research on Imperva blocking denial-of-service attacks, and I like practical evidence of issues such as this. By reading these articles, and about other people's experiences, it is like seeing it for myself. With other solutions, you are not privy to such visibility.
Complexity and cost are two important factors when it came to choosing this solution.
Unless the client has as serious issues and does not want Imperva, this is my first choice.
How was the initial setup?
The initial setup of this solution was not too straightforward. We did have to contact Imperva during the deployment. The length of time for deployment depends on the experience of the people performing the installation, as well as the environment.
What about the implementation team?
My team and I performed the implementation of this solution. To make sure that we were on track, we contacted Imperva support for some clarification. Most of the things that we do, we follow best practices.
What's my experience with pricing, setup cost, and licensing?
Everybody complains about the price of this solution.
What other advice do I have?
This is a security device, and it is used almost every day. It is not just used when there is an issue. Based on what the dashboard or the reports say, you can change policies to meet your security requirements or business needs.
Based on my experience, and what I know this product can do, I would never recommend another solution. I advise most of my customers to go for this.
I would rate this solution a nine out of ten.

Manager, IS Security & Infrastructure at Fintech Kenya Limited
User-friendly with good performance and helps to secure digital assets
Pros and Cons
- "It mitigates all of the availabilities of risks around web applications."
- "Their portal is very limited and needs improvement."
What is our primary use case?
We are a reseller and integration partner, and we have customers who are using this solution in on-premises deployments.
How has it helped my organization?
This solution has helped in securing our clients' assets, which is key. It mitigates all of the availabilities of risks around web applications.
What is most valuable?
The most valuable feature of this solution is web application security.
This is a user-friendly solution.
This solution has good performance ratings.
What needs improvement?
I would like to see more support available for this product online. Some customers find this to be a real limitation.
The virtual processing could be improved.
Their portal is very limited and needs improvement.
For how long have I used the solution?
We have been using this solution for close to five years.
What do I think about the stability of the solution?
This is a very stable solution.
What do I think about the scalability of the solution?
The solution is very scalable, but of course, the scalability comes with a cost.
How are customer service and technical support?
I think that technical support needs to be improved by making it more localized, or regionalized. Our support is currently coming from the US, and it is not very good. They need to take care of their global customers.
Which solution did I use previously and why did I switch?
We previously used Fortinet, but this solution has better performance ratings.
How was the initial setup?
I don't want to say that the initial setup is straightforward, but it is manageable. It requires a bit of technical knowledge.
What other advice do I have?
This is a solution that I highly recommend.
The biggest lesson that I have learned from this solution is that Imperva is not a one-house solution. They create a specialized solution, and that comes with a lot of value.
I would rate this solution a nine out of ten.

Specialist Engineer at Entel Networks S.A
Valuable compliance features and has good stability
Pros and Cons
- "The compliance is the most valuable aspect."
- "It's a complicated tool to keep."
What is our primary use case?
The primary use was to cover the database. Imperva we recognized on the market as the best solution for techs on databases. The banks here in Chile always ask for these types of solutions.
What is most valuable?
The compliance is the most valuable aspect.
What needs improvement?
I just need it to be a stable and normal version. I'd want to hear about the new features to see which I would need.
For how long have I used the solution?
I've been using the solution for 2 years.
What do I think about the stability of the solution?
I find this solution stable. We have 2,000 users in financial services.
What do I think about the scalability of the solution?
The solution is scalable.
How was the initial setup?
The setup initially was simple, but when we tried to run it we had problems with the log parameters and it was complicated to use. The operation was complicated to use, but that is just the experience of my team. It took two months to deploy. The setup and installation of the technologies took one week, and after that, one month to set up the parameters and after that, in order to set up the logs, it took about two weeks. So two months total. We have three engineers, including an architect and a security engineer. We also had a fourth engineer that knew the application.
What's my experience with pricing, setup cost, and licensing?
We have a yearly license, but I'm unsure of the pricing.
Which other solutions did I evaluate?
We didn't evaluate other options, just Imperva.
What other advice do I have?
I would rate the solution as an 8 out of 10, simply because of the difficulty of operation management. It's a complicated tool to keep.
