Imperva Web Application Firewall (formerly Incapsula) is positioned as a cloud WAF and DDoS protection online service, comparable to similar cloud WAF/CDN security products. Available material shows its security blog covering Web protection scenarios such as XSS abuse, traffic hijacking, and DDoS mitigation.

The available material does not specify a self-hosted form, hardware requirements, or bandwidth requirements; confirm localization/private deployment capabilities with the vendor before deployment. Users in China should also test compatibility for WeChat in-app access, ICP filing requirements, domestic cloud/CDN environments, payment, and support tickets.
