In last month we developed our Arbor Network based DDoS mitigation. We worked hard to tuning and test new mitigation system against many type of attacks and the result was fantastic, it was able to handle our test attacks in size of 70Gbps and many other type of attacks like TCP-SYN and TCP-ACK for long time. The attack detection time was around 30-80 seconds which is good. You have control over your network traffic and you can adjust many config during mitigation process for better mitigation. At all it is better than all mitigation systems we tested so far, this is why the Arbor is one of best and leader in DDoS protection industry.
