Imperva WAF

Imperva WAF (on-premises) is a web application firewall appliance that provides inline protection for web applications and databases against application-layer attacks. It offers protection against SQL injection, cross-site scripting, remote file inclusion, and other OWASP Top 10 vulnerabilities, along with virtual patching capabilities. 

Imperva WAF provides granular security policies, custom rules, and dynamic profiling that learns legitimate application behavior to reduce false positives. Its detailed security logs capture request-level information including attack payloads, violated policies, source details, and session context, providing forensic evidence for investigating application security incidents.
