Deploy Imperva WAF on-premises, in AWS and Azure, or as a cloud service itself. Easily meet the specific security and service level requirements of individual applications.

Imperva WAF protects against the most critical web application security risks: SQL injection, cross-site scripting, illegal resource access, remote file inclusion, and other OWASP Top 10 and Automated Top 20 threats. Imperva security researchers continually monitor the threat landscape and update Imperva WAF with the latest threat data.

Useful out-of-the-box threat protection, not too complex, and has good technical support

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.

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 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.

Dual perspective of positive and negative security makes for optimal protection

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.

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 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…

It is easy to deploy, manage, and expand

Pros and Cons

  • "Its inline transferring mode is the most valuable because it is 100% transparent. When you change the IP, there is no change on the network side. If you can't and want to try to reach an IP, you can reach the server IP. There are many other advanced security features in it. The smallest appliances of Imperva can handle the highest traffic at a customer site. For example, a smaller appliance from Imperva can provide you the same security as an F5 product."
  • "They can provide an option to create reports, automatically import the entire report, and create rules again. In a real-life crisis, it would be helpful to be able to import a report and generate security rules from that report. I should be able to create a simple query and import the reports automatically. It can maybe also tell us the format of the report."

What other advice do I have?

In Turkey, we mostly have on-premises deployments. There are some Azure Amazon projects, but it is mostly deployed on-premises. It is not so easy to send Incapsula solutions to Turkey. I would recommend this solution. It is easy to manage and expand. I would rate Imperva SecureSphere Web Application Firewall a ten out of ten.

Provides good network transparency and integrates well with other products

What is our primary use case?

We are a solution provider and Imperva is one of the products that we implement for our clients. They use it as an application firewall.

Pros and Cons

  • "If you are using the appliance as opposed to the virtual deployment, it can stand as the network layer-two and provide real transparency."
  • "The user interface could be better."

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.

User-friendly with good performance and helps to secure digital assets

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.

Pros and Cons

  • "It mitigates all of the availabilities of risks around web applications."
  • "Their portal is very limited and needs improvement."

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.

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 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.

Valuable compliance features and has good stability

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.

The setup initially was simple,…

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 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.
