DDoS Protection

DDoS Protection with 2 Tbps

DDoS (Distributed Denial of Service) attacks have been on the increase recently. These involve remote-controlled networks of compromised computers ("botnets") overloading services on a server by sending a huge number of requests. We offer an anti-DDoS filter with a bandwidth of 2 Tbps for all our root server, managed server and dedicated server solutions. This filter is activated automatically as soon as your server experiences an unusually large number of incoming packets or an equivalently high bandwidth of traffic from the Internet. Thanks to our comprehensive protection against DDoS attacks, the Anexia DDoS Guard, we protect your infrastructure against attacks up to layer 4.


The following diagram illustrates how our DDoS filter works to block attacks.

If no attack is taking place, traffic from the Internet is routed directly to the servers via the routers. Traffic is analyzed on the routers to identify potential attacks.

If an attack is detected, the routers then redirect Internet traffic to pass through the DDoS filter. This filter blocks packets marked as "bad". "Good" packets are routed to your servers after passing through the DDoS filter. This ensures the availability of your servers.

Once the attack dies down, traffic is once again routed directly to your server by the routers. With our comprehensive DDoS protection, we make sure, that the availability of your server, web application or infrastructure is guaranteed.
