  • Cloud WAF: Imperva Cloud WAF protects against known and unknown threats, including all OWASP top 10 and zero-day threats.

    Imperva Cloud WAF is designed to work in blocking mode with little or no tuning and with near zero false positives. You can easily build custom WAF rules and secure your API interfaces. Automated virtual patching lets you protect all apps with a single change. More than a WAF, Imperva also adds bot control, account takeover protection, backdoor protection, two-factor authentication and SIEM integration.
  • WAF Gateway: Web attacks deny services and steal sensitive data. Imperva Web Application Firewall (WAF) Gateway analyzes and inspects incoming requests to your applications and APIs and stops these attacks.

    WAF Gateway inspects and analyzes all requests to your websites and APIs and protects them from attacks aimed at exploiting vulnerabilities and from automated attacks.Machine learning creates a positive security model of the application’s profile to avoid false-positives. WAF Gateway dynamically learns normal application behavior and distinguishes it from the abnormalities of an attack.

Stop OWASP Top 10 and Automated Top 20

Imperva WAF protects against the most critical web application security risks: SQL injection, cross-site scripting, illegal resource access, remote file inclusion, and other OWASP Top 10 and Automated Top 20 threats. Imperva security researchers continually monitor the threat landscape and update Imperva WAF with the latest threat data.

How Imperva WAF Protects Your Applications

  1. 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.
  2. 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.
  3. 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.
