Game Security Solution
Best Practice
KAD defends against DDoS attacks and scrubs attack traffic. This helps you defend against various types of DDoS attacks and CC attacks at the application layer. KAD also hides the IP address of a real origin server to ensure proper business operation of the origin server.
