hi @MP18

 

You'll want to use both

Zone protection protects an entire zone while DoS protection protects a resource (a single server or a farm).

Configure DDos protection profile as to secure perticular server or subnet. while zone protection provides protection based on the interface /zone and will be application for whole zone.

@MP18

Be careful with the protection of UDP services, as these could be spoofed easily which could result in bringing your services partially "offline" when source IPs of big DNS players (like google, cloudflare, ...) are blocked by your zone/DoS protection.
