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

"Configuration for different application sources is most valuable. We can segregate the traffic that an application is carrying and identify the sizing in Imperva."
"It's a good product."
"Imperva Application Security Platform has positively impacted my organization by making the website more secure."
"The solution is really stable; it's a product that I can stand by and recommend because I know it's going to work for the customer."
"Well, just by using the security rules to block all secured areas by IP minimized the chance of sensitive data leaking outside."
"It is the best product on the market, in my opinion."
"The most valuable feature of Imperva DDoS is to make our website available for our customers' requests 24 hours a day."
"Learning mode and custom policies are helpful features."
"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."
"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."
 

Cons

"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."
"I would like to improve the tool's turnaround time in terms of support."
"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."
"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."
"Certificate management could be improved."
"We rate technical support as really bad."
"I would like to have support for SSL management and secure DNS."
"The tool needs to include artificial intelligence and machine learning. It also needs to improve profiling."
"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."
"Genuine traffic coming in is still getting better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked."
 

Pricing and Cost Advice

"The tool's pricing is good."
"There is a license or subscription renewal that our customers pay."
"It is a very affordable solution."
"It is not expensive compared to the other similar solutions in this category."
"The pricing is somewhat expensive. It is actually a huge investment when compared to other countries."
"The price is high compared to other solutions like FortiWeb."
"The tool is expensive."
"Make sure you understand the way that Imperva charges. It's very affordable. However, I would like to see a package with the Virtual Patching included. You get to do patching separately."
