Features and Benefits


Comprehensive DDoS Attack Protection

NSFOCUS ADS not only defends against attacks on the transport layer, such as SYN Flood, SYN-ACK Flood, ACK Flood, FIN/RST Flood, UDP Flood, ICMP Flood and IP Fragment Flood attacks, but it also defends against attacks targeting the application layer, such as HTTP GET /POST Flood, slow-rate, DNS, game service and audio/video attacks.

Lowest False Positive and Negative Rates

Unlike other DDoS products that only focus on fingerprint matching or heuristics to mitigate DDoS attacks, NSFOCUS ADS uses a multi-stage inspection and analysis process that combines anti-spoofing, protocol behavior analysis, user behavior analysis, specific application protection, dynamic fingerprint identification, bandwidth control and more to mitigate attacks. This comprehensive approach leads to the lowest rates of both false positives and negatives as compared to any other technology. Not only is it highly accurate, it is also highly efficient in cleaning attack traffic.

Flexible and Scalable Deployments

Available in a range of performance-optimized appliances, the ADS Series has been designed to meet the needs of any size organization without modifying existing applications or purchasing additional hardware.
