Anti-DDoS

NSFOCUS provides comprehensive, end-to-end protection from the debilitating effects of DDoS attacks.  Our Anti-DDoS solution provides maximum flexibility and complete coverage through on-premises equipment, cloud-based detection and mitigation services, or a hybrid offering that combines the strengths of both approaches.

NSFOCUS Anti-DDoS System (ADS)
Distributed Denial of Service (DDoS) attacks can cause substantial disruptions to the availability of Internet-facing online services. They can bring all operations to a halt, impact the customer experience, and result in economic losses. NSFOCUS ADS is a custom-built appliance that inspects network traffic, detects DDoS attacks and mitigates them intelligently without affecting legitimate traffic. As a result, ADS automatically provides 24×7 business continuity and maintains quality of service.

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.

*Requires NSFOCUS NTA

These appliances are designed for high availability: a single device can clean up to 40Gbps of attack traffic at network speeds. ADS can be scaled up to 1Tbps or higher using cluster mode in combination with the NSFOCUS Network Traffic Analyzer (NTA).

NSFOCUS Anti-DDoS for Large Deployments
The NSFOCUS DDoS Protection Solution uses a scalable architecture that is performance optimized to meet the current and future needs of large enterprise and service provider environments. Designed for network environments that require more than 40 Gbps of DDoS mitigation capacity, it uses a distributed architecture that separates DDoS mitigation, threat detection and management to allow independent scaling in each of these areas.  It can also be clustered and deployed in an out-of-path mode to provide hundreds of Gbps – and beyond – of mitigation capacity.

Network Traffic Analyzer (NTA)
NSFOCUS NTA is a threat detection appliance that identifies malicious traffic.

Anti-DDoS System (ADS)
The NSFOCUS ADS appliance leverages a multi-stage inspection and analysis process that uses a comprehensive approach to achieve the lowest rates of both false positives and negatives in the industry. Not only is it highly accurate, it is also highly efficient in cleaning attack traffic.

Anti-DDoS System Manager (ADS-M)
The ADS-M is a multi-tenant management system designed for service providers or large enterprise data centers.  It provides centralized management of the ADS and NTA appliances, as well as support for multiple, separate configuration and reporting domains by end-customer.
