The best feature I would say is the compliance. It satisfies enterprise audit criteria for web application profiling that is required by PCI DSS and HIPAA. Also, it aligns fully with my security compliance matrices, the OWASP Top 10 alignment, and standard core rules to defend against injection attacks, cross-site scripting, and path traversal. These are the major features. The managed rule set proves that modern security does not have to be slow or complicated. It turns threat intelligence into a utility function that I can enable with a few clicks. It has eliminated the heavy operational burden of threat research. Instead of my internal security engineers spending hours tracking new malicious IPs or writing custom regex signatures to deal with emerging exploits, Imperva automatically updates the rule set in the background.
