SonicWall WAF features advanced web security tools and services to keep compliance data unexposed and web properties safe, undisrupted and in peak performance. It employs a combination of signature-based and application profiling deep-packet inspection, and high-performance, real-time intrusion scanning engine using event-driven architecture to dynamically defend against evolving threats as outlined by the Open Web Application Security Project (OWASP), as well as more advanced web application threats like denial-of-service (DoS) attacks and context-aware exploits. The SonicWall WAF behavior-based detection engine learns, interrogates and baselines regular web application usage behaviors and identifies anomalies that may be indicative of attempts to compromise the application, steal data and/or cause a denial-of-service.
