Best Practice

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.

Game Security Solution

KAD provides one-stop security protection and security O&M experience for all game types, including mobile games, client games, and browser games. It supports multiple protocols and allows you to use leased lines for back-to-origin.

Reliable Solution to Prevent CC Attacks in Games

KAD implements strict authentication based on data packets. Only the traffic of normal game clients is allowed. This defends against complex CC attacks that target games.
