Hillstone WAF employs a dual-engine approach combining traditional rules-based detection with semantic analysis to enhance accuracy and reduce false positives. It leverages machine learning to optimize security policies and defend against unknown threats, offering protection against network layer attacks such as DDoS and application layer threats including OWASP Top 10 risks. The solution provides API protection, automated policy generation, and log aggregation for anomaly detection and policy refinement. Available in both virtual and hardware forms, Hillstone WAF supports multi-tenancy and scalable deployments across cloud and on-premises environments.
