Imperva (Thales Group)

Imperva Cloud WAF (Web Application Firewall) is a cloud-based application security service that protects websites and applications from web attacks, DDoS assaults, and malicious bots. It operates as a reverse proxy, inspecting all incoming traffic and blocking threats before they reach the origin server, while also providing CDN acceleration and load balancing. 

The platform uses a combination of signature-based detection, behavioral analysis, and reputation intelligence to identify threats. Imperva Cloud WAF logs provide detailed records of all HTTP/HTTPS requests including security alerts, blocked attacks, bot classifications, and client reputation scores, enabling security teams to analyze attack patterns and investigate web security incidents.
