Application protection has improved and reporting and dashboards still need refinement
I believe Imperva Application Security Platform should have a more interactive wizard. While the dashboard is good, it could be more eye-catching. Based on my perspective, I recommend modifying the dashboards, especially the main dashboard where I can see the traffic hit count, alerts, and other latest information. In terms of reporting, I find it challenging to create reports; in my earlier days, it was difficult. Over time, I have learned how to create reports, but it should be easier to do so. I have used other tools such as firewalls or SolarWinds, where creating a report is straightforward and does not take much time, unlike in Imperva, where I have to add many elements. Modifications in the integration aspects would also be beneficial.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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!"
"Imperva is easy to use and deploy, and the UI is excellent."
"Provides Anti-DDoS protection, as well as other protections like SQL injection, Cross-Site Scripting, and antiscanner. These types of protection are valuable to the business due to the daily attacks on our portals, and that often cannot be seen without a tool like this."
"Thanks to Incapsula, we got easily manageable DDoS protection; HTTP2 and SSL certificates for all the services; CDN in good locations; and we're now sure that our web services can't be exploited remotely because of the WAF feature."
"It's worth it. It's a fine solution for medium/big companies worried about attacks that happen in the wild."
"If you are using the appliance as opposed to the virtual deployment, it can stand as the network layer-two and provide real transparency."
"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."
"Essentially, it has added an extra layer of protection to my clients through their DNS routing service."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"They could improve by minimizing false positive results."
"The product could use a broader scope in the area of policies."
"It is complicated to integrate the solution's on-cloud version with other platforms."
"The reporting is missing some features, such as: only two export formats, and the time period does not include the last day, week, year."
"We had an issue when securing the web applications for DDoS protection."
"There’s nothing that’s missing in terms of features."
"I would say that technical support is average."
"Incapsula services also provides load balancing services for their service IP address environment. So far, with monitoring their services, the IP address was only changed once."
"If Radware provides a separate web service like those offered by vendors such as F5 and Imperva, that would be better."
 

Pricing and Cost Advice

"There is a license for this solution and we purchase the license annually with no additional fees."
"There is a license or subscription renewal that our customers pay."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"Imperva Web Application Firewall's pricing is expensive."
"It is a very expensive solution. The price is very high. A lot of customers tell us that they would love to use Imperva more. I have some customers who have 50 websites, but they have only 10 websites on Imperva because of the price. They would love to have all their websites running through Imperva, but they can't. They have to choose the more critical websites to protect because the price is very high. It is a very good product, but it is too expensive. If you buy a plan for 20 megabytes and you don't consume all of your 20 megabytes, it is okay, but if you consume more, you are charged for the superior traffic."
"It is very costly, but the return on investment is very high. Its cost was around $70,000, and we got it back in just six months."
"The solution's price is high for small companies."
"There are some licenses that you have to buy to use some features. Its price could be better. Price is always important because, at the end of the day, customers have a budget. If you can meet the budget, you can sell, and if you don't, you cannot sell."
