That is an attack over 10 gigabit per second, and if an attack enters the telecommunication network, that will be a disaster for their customer, their services, and so on.
Team Lead Network Engineer at Artco Group d.o.o Sarajevo
We have many updates for the library of different attacks, and they have artificial intelligence that automatically learns the process during different attacks.
CTO at UkrNet
You can generate flow spec filters. These filters are transferred through BGP to border routers, which automatically build filters, mitigating the attack even at the network's boundary and preventing it from reaching the TMS.

Automated threat detection has reduced staffing needs but dashboard design still needs improvement
Link11 offers high-performing platform capabilities and automated responses. The system operates on its own cloud infrastructure without requiring my input. The automated responses have helped my team and my workflow by reacting to threats in real time and helping mitigate attacks within moments instead of relying on manual alerts and manual response processes. Link11 has positively impacted my organization by helping analyze all incoming traffic continuously, functioning like an employee operating in the background. This background analysis has affected my organization's security and efficiency in that I do not have to worry about it. It operates on the back end automatically, taking care of things that I do not have to worry about or think about, but I know it is working.

Automated threat intelligence and flow-based mitigation have improved our DDoS defense
A very useful feature in Arbor DDoS is its ability to send flow spec announcements to routers. For example, if it is clear that a Layer 3 or Layer 4 attack is occurring and the attack pattern is identified through source and destination IP addresses and ports, you can generate flow spec filters. These filters are transferred through BGP to border routers, which automatically build filters, mitigating the attack even at the network's boundary and preventing it from reaching the TMS. This allows the TMS to focus on other tasks. This is a highly effective feature that can mitigate huge volumetric attacks; for example, we experienced a 32-gigabit attack, and all those 32 gigabits were dropped by our border routers, not by Arbor DDoS itself. The flow spec announcement was generated by Arbor DDoS, and as far as I know, the same technology is used by Radware, but it comes under a different feature and a different license. At the time, we were told that flow spec mitigation was an additional very expensive license to purchase from Radware, while Radware included everything in one package.
