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.

Identifies a request that comes up multiple times, block holds that particular IP, and lets the genuine traffic pass through
Genuine traffic coming in is still getting better. While I understand that it's some sort of algorithm that is written in this scale, that algorithm can be a little bit better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked. While it is one of the greatest features it can still be improved. I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense.

Quotes from Members

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

Pros

"The tool's profiling feature maps all the web application directories and related components on the profile directory. It has improved the security of my client's website applications."
"I see valuable benefits from advanced detection and traffic profiling during DDoS attacks, and I track some metrics related to DDoS protection performance."
"It's worth it. It's a fine solution for medium/big companies worried about attacks that happen in the wild."
"The solution can scale."
"​Technical support provides good, quick responses."
"I am impressed with the product's automatic bot mechanism. It also gives us the control to create our own custom bot rules."
"Data masking is the most valuable feature of this solution."
"It is an effective threat mitigation tool."
"Scalability is awesome, and they have grown two folds or three folds since we started using them, with no concerns even as we protect close to 60,000 hosted sites for business and e-commerce customers."
"In the DDoS it's difficult to validate what is a genuine request from an end user. We've started being able to do that with the logistics that they have set up. With the protection that they have provided, they are able to identify what is valid and what is not valid. We see that a person who is getting DDoS Neustar service is able to block that particular user. However, while they are doing that it doesn't affect other customers on the server."
 

Cons

"I would like the solution to improve its support response time."
"Reporting and the main Sites dashboard could use refinement."
"Pricing is a challenge for most of our customers."
"The UI interface needs improvement."
"We've had some issues with them in terms of response times, but overall they are okay."
"If I had the opportunity to recommend an enhancement to Imperva it would be to have more POP (Point of Presence) in East and West Africa, and in Central Africa as well."
"It needs to be improved every time there are new attacks."
"It's quite expensive."
"Genuine traffic coming in is still getting better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked."
"I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense."
 

Pricing and Cost Advice

"Imperva’s pricing is a bit higher in the market since it offers a full-blown WAF."
"Imperva Web Application Firewall is expensive."
"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."
"The cost of this solution depends on the platform."
"The license is on a yearly basis."
"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."
"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
