IP Protection helps SMBs defend against DDoS attacks with enterprise-grade DDoS protection at an affordable price point. With IP Protection, you have the flexibility to enable DDoS protection on an individual public IP resource.
IP Protection provides the same capabilities as the Network Protection SKU though Network Protection offers additional features such as DDoS Rapid Response support, cost protection, integration with Azure Firewall Manager, and discounts on Azure Web Application Firewall.
