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.

Helps us to monitor attacks to our sites and prevents a lot of them
Set up Wallarm as a reverse proxy. Do not replace your web server. Use Wallarm first in monitoring mode, then learn from Wallarm which type of request is false positive and which type of request is not. This process takes a couple of weeks for very highly-loaded web applications (few millions of unique visitors in one month). Then you can turn Wallarm into blocking mode and everything will be fine. Do not forget to build a monitoring system, the wave, and API for it. Before we started using Wallarm, I already knew Ivan (CEO) and Stepan (COO) from a couple of years before. Ivan had his own security company and Stepan was working on a Russian security magazine called Xakep. They told us that they wanted to create a new WAF and already had a working version of it. They asked me to test it. We did tests, and it was really good. After few month after testing, we signed an agreement. Our choice was made not because we knew these guys for a long time, but because the product was really cool and we were glad to start using it as one of the first on the market!

Quotes from Members

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

Pros

"The technical support is excellent."
"Its unique interface for managing security performance and ease of use are the most valuable features of this solution."
"Deployment is simple and very fast."
"Scalability has been pretty good, our European traffic has doubled and our sales have gone up along with our stability."
"Imperva anti-DDoS protection has the well-known value of having lots of distributed nodes around the world, making it the best value for DDoS protection."
"Imperva Cloud WAF would be the most powerful option."
"I find the configurability of the tools and the ease of operation to be the most valuable feature of Imperva."
"Well, just by using the security rules to block all secured areas by IP minimized the chance of sensitive data leaking outside."
"Helps us to monitor situation in regards to attacks to our sites and prevents a lot of them."
"The most powerful feature is the ability to first learn what type of query to make to your web application when it is attacked and what type of query creates a false positive to your app."
"Perimeter control and active vulnerability scanner are the most valuable features."
"Vulnerability scanner and WAF are valuable features."
"With active threat detection, we are no longer over-swamped with tons of useless events."
"They are the only solution that fits our success criteria and business objectives: WAF must have a low (<5%) false negative rate and be ready to protect from all well-known web attacks."
 

Cons

"We looked at CloudFlare. We tried it but it didn’t work that well."
"One potential improvement for Imperva is enhancing its alert system."
"Licensing should be improved. Most of the clients aren't happy. It's expensive."
"However, I'd like to be able to drill down more into the analytics that Incapsula collects."
"Sometimes, support tickets don't get addressed quickly."
"The price of this solution is a little bit high compared to competitors."
"Reporting and the main Sites dashboard could use refinement."
"The interface seems a bit outdated and simplistic."
"There were several stability issues during the first pilot."
"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."
"Technical support is 6 or 7 out of 10. Sometimes we have had trouble with communication and understanding."
"It needs more customization in PDF reports."
"Wallarm uses a learning mechanism to detect attacks and to avoid false positives. If Wallarm blocks some illegitimate request, then you can go to the management console and mark this request as false positive, but sometimes this does not work properly."
 

Pricing and Cost Advice

"It is a very affordable solution."
"The license is on a yearly basis."
"It's an excellent product, but it can be very costly."
"It is expensive."
"There are a couple of different licensing models."
"The solution's price is high for small companies."
"The price is high compared to other solutions like FortiWeb."
"The cost of this solution depends on the platform."
"​Pricing must be cheaper than the competition and the licensing must be good.​"
