Network & DDoS Threat Protection Appliance
 SmartWall® Network Threat Defense 1100

Real-time protection against DDoS Attacks - SmartWall NTD1100

Disruptions to Internet service availability as a result of Distributed Denial of Service (DDoS) attacks can cripple operations, impact customers and result in major economic losses. 

The SmartWall Network Threat Defense 1100 (NTD1100) allows real-time, line-rate, DDoS detection and automatic mitigation, to 100 Gigabit Ethernet connections. Protection is delivered in a compact 1 RU form-factor – an industry first – scaling to 4Tbps of protection in a single rack.

The SmartWall NTD1100 is  dedicated technology for real-time mitigation of DDoS attacks in seconds vs minutes (in contrast to legacy solutions), allowing good user traffic to flow uninterrupted. With varied deployment topologies, (In-line or  scrubbing) the SmartWall NTD1100 utilizes modern DDoS mitigation architecture to automatically, and surgically remove DDoS attack traffic. 

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.

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 NTD1100 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.
