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

"Incapsula has provided heightened visibility and awareness at management level on the actual threat landscape; it paves the way for easier approval for security-related implementations and projects."
"The solution can scale."
"The most valuable features of the Imperva Web Application Firewall are DDoS, malware, and the other malicious threat prevention it provides. Additionally, third-party integration is available. You can forward the log for further analysis."
"Imperva Web Application Firewall is used for customers who are looking to secure their multiple applications and want to block threats such as DDoS and ransomware attacks, delivering data security, data availability, and access control."
"For me, it is the best solution available."
"The solution has been quite stable. I have not seen any bugs at all."
"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 solution is very affordable; it's based on the average traffic utilization, not the DDoS traffic, so if you're being DDoSed, you don't pay extra for the absorption of the DDoS traffic."
"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

"I think that better bot protection is needed in this solution."
"Everybody complains about the price of this solution."
"I loved the approach of the cloud. The cloud has a lot of new features, like advanced web protection and DDoS protection. If those could also be on-boarded onto the on-prem versions, that would be ideal. They need to pay attention to both deployment options and not just favor one."
"On the negative side, API security mainly supports cloud-based solutions, while most of my customers prefer on-prem setups, so achieving high performance with on-prem solutions would be beneficial."
"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."
"As such, I have not seen a return on investment."
"The log analytics interface within Incapsula isn't really good. For example, if you have to get all logs from there, it's a very cumbersome process."
"We've had some issues with them in terms of response times, but overall they are okay."
"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

"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."
"We are satisfied with the pricing."
"There is a license for this solution and we purchase the license annually with no additional fees."
"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."
"The tool's pricing is good."
"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."
"Pricing could be more competitive."
"The pricing is somewhat expensive. It is actually a huge investment when compared to other countries."
