Open rules have enabled me to secure web apps against obfuscated SQL injection and XSS attacks
The best feature Atomic ModSecurity Rules offers is the open source aspect. I believe that because it's open source, all of the developers, programmers, and security experts are able to update this WAF and provide more rules, creating a more secure WAF for all of the clients and customers around the world. By accessing Atomic ModSecurity Rules, it has helped me significantly. Because of this open source feature, I am able to generate new rules and update the WAF and use this WAF in my research and also give it to other clients and customers to use the updated WAF. All of this is done just because of the open-source feature, because it can be updated.

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.

Pros

"The best feature Atomic ModSecurity Rules offers is the open source aspect, because all of the developers, programmers, and security experts are able to update this WAF and provide more rules, creating a more secure WAF for all of the clients and customers around the world."
"Customer Service: Excellent, they answered all our questions."
"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."
"For me, it is the best solution available."
"Scalability is pretty easy on the base platform. You just add another, and you're ready to go."
"This implementation helped our organization a lot in handling web attacks by hackers and other malicious intruders."
"The most valuable features of the Imperva Web Application Firewall are performance and flexibility, and we can extend or customize the box itself."
"Imperva Application Security Platform has positively impacted my organization by providing strong protection for web applications, as many big companies in the UK use Imperva WAF as an essential protection layer, illustrating its effectiveness."
"It is easy to use and has good security."
 

Cons

"Additionally, I know that ModSecurity can block only SQL injection and XSS attacks, no more types of attacks."
"The reporting is missing some features, such as: only two export formats, and the time period does not include the last day, week, year."
"Imperva should have more points of presence in Africa."
"The main reason it is not a perfect ten is regarding support. At times, having to reach the support team takes eight hours to ten hours maximum."
"Our support is currently coming from the US, and it is not very good."
"The tool needs to include artificial intelligence and machine learning. It also needs to improve profiling."
"Incapsula has a built-in monitoring module, but it is a paid feature; I would expect that for the price we pay for the basic service, we would be able to integrate a monitoring solution, even a simple one."
"There's always room for improvement. Occasionally, there might be false-positive alerts."
"I would like to have support for SSL management and secure DNS."
