NetFlow DDoS Detector

Powerful Add-on: Flow-Based DDoS Detection

Not every company requires always-on protection. The Link11 NetFlow DDoS Detector offers you a powerful add-on that allows you to analyze NetFlow data independently and decide when to redirect traffic to us.

In the event of an attack, the system automatically reroutes traffic based on your predefined settings. With our technology, you gain deeper insights into network traffic, enabling earlier attack detection and faster response — enhancing security and efficiency like never before.
