Network & DDoS Threat Protection Appliance
 SmartWall® Network Threat Defense 

Real-time protection against DDoS Attacks - SmartWall NTD120

Disruptions to Internet-facing services due to Distributed Denial of Service (DDoS) attacks can cripple operations, impact customers and result in major economic losses. The SmartWall Network Threat Defense 120 appliance (NTD120) is an intelligent, always on appliance that inspects traffic, detects threats and blocks DDoS attacks targeting protected network resources. It allows service providers, hosting providers, and online enterprises to deploy centralized or distributed DDoS attack protection solutions via purpose-built network security appliances that provide real-time Layer 3-7 mitigation against volumetric attacks for both IPv4 and IPv6 traffic.

The SmartWall NTD 120 is a next-generation slim line DDoS protection appliance delivers 10Gbps full duplex or 20Gbps unidirectional performance in a ¼ wide, 1 RU form factor. It is a member of the Corero SmartWall Threat Defense System (TDS), an innovative family of security platforms that will change the rules for inspection performance, security intelligence and network forensics, while providing an unprecedented level of scalability for protection against DDoS attacks. 

With varied deployment topologies, (In-line or  scrubbing) the SmartWall NTD family of solutions utilizes modern DDoS mitigation architecture to automatically, and surgically remove DDoS attack traffic. 

This groundbreaking new appliance provides configurable policies to selectively enable a broad range of specific protection mechanisms to defend critical network assets against suspicious or malicious traffic types while allowing uninterrupted service access to legitimate users and applications. The SmartWall TDS also utilizes the concepts of Flex-Rule and Smart-Rule technology to apply granular detecting and blocking filters to a very specific DDoS attack with ease. These rules, leverage heuristic and closed loop policy, allow for rapid creation and deployment, thereby providing customers with the ability to respond rapidly to the evolving nature of sophisticated DDoS attacks.
