"The features I have found most valuable with Imperva Web Application Firewall are account takeover protection, advanced bot protection, and API security."
"The most valuable feature of Imperva, in addition to its strong knowledge base, is its effective protection for web applications."
"Imperva WAF's strongest features are the detection of web application threats and vulnerabilities in the source code."
"Configuration for different application sources is most valuable. We can segregate the traffic that an application is carrying and identify the sizing in Imperva."

"One potential improvement for Imperva is enhancing its alert system."
"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 is complicated to integrate the solution's on-cloud version with other platforms."
"They recently separated the WAF and the DAM management gateways in order for each of these to be managed from different areas, so I believe it now requires additional investments for what was previously a single complete solution."
"The signature updates could be faster. Sometimes we have to upload signatures to the Imperva portal for checking and analysis before we can use them."
"The tool needs to improve CPU and storage memory."
"An improvement for Imperva WAF would be to reduce the number of false positives and create more strong use cases based on AI/ML or behavioral analytics."
"I don't really use it and therefore can't speak to areas of improvement."
"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
