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

"Imperva is a good solution; it has fewer false positives, is very simple to maintain, and is also simple to configure without needing any HTTP knowledge or understanding of HTTP programming languages."
"There are many features. There is ease of deployment. You can deploy the Imperva Web Application Firewall in two to three minutes. After that, you have to set the policies. For setting policies, you have toggle buttons. You can turn something on or off."
"The user-generated spam stopped after we started using Incapsula, and so we feel more secure."
"Imperva Web Application Firewall is stable."
"The most valuable feature of Imperva DDoS is to make our website available for our customers' requests 24 hours a day."
"The solution offers good security against a variety of web attacks, and the protection from DDoS attacks is very useful."
