How Imperva WAF Protects Your Applications

Attack detection

Imperva WAF uses patented dynamic application profiling and correlated attack validation to accurately detect attacks and minimize false positives. Dynamic application profiling learns all aspects of web applications, including the directories, URLs, parameters, and acceptable user inputs. Correlated attack validation aggregates and analyzes individual violations across the stack. Combined, they detect attacks with exceptional accuracy and block only bad traffic.

Extensive reporting

Imperva WAF offers rich graphical reporting capabilities to easily understand security status and meet regulatory compliance. Generate pre-defined and customizable reports. Quickly assess security status and streamline demonstration of compliance with PCI, SOX, HIPAA and FISMA and other compliance standards. Benefit from our best-in-class integrative attack analytics and intuitive single pane of glass dashboards.

SIEM integration

Imperva WAF integrates with most of the leading Security Information and Event Management (SIEM) systems such as Splunk, ArcSight and others. It exports events as syslog messages, Common Event Format (CEF) and JSON format. Events generated by Imperva WAF are intuitively indexed and easily searchable for quick incident response.
