Through DNS Application Groups, you can create groups based on DNS tunneling traffic as well as other web applications. By allowing or blocking traffic at the DNS level, you gain greater granular control and can create new firewall policies applied specifically to these groups. To learn more about tunneling detection, see About DNS Tunnel Detection.
