About Azure DDoS Protection tier Comparison

  • Article

The sections in this article discuss the resources and settings of Azure DDoS Protection.

Tiers

Azure DDoS Protection supports two tier types, DDoS IP Protection and DDoS Network Protection. The tier is configured in the Azure portal during the workflow when you configure Azure DDoS Protection.

The following table shows features and corresponding tiers.

Feature DDoS IP Protection DDoS Network Protection
Active traffic monitoring & always on detection Yes Yes
L3/L4 Automatic attack mitigation Yes Yes
Automatic attack mitigation Yes Yes
Application based mitigation policies Yes Yes
Metrics & alerts Yes Yes
Mitigation reports Yes Yes
Mitigation flow logs Yes Yes
Mitigation policies tuned to customers application Yes Yes
Integration with Firewall Manager Yes Yes
Microsoft Sentinel data connector and workbook Yes Yes
Protection of resources across subscriptions in a tenant Yes Yes
Public IP Standard tier protection Yes Yes
Public IP Basic tier protection No Yes
DDoS rapid response support Not available Yes
Cost protection Not available Yes
WAF discount Not available Yes
Price Per protected IP Per 100 protected IP addresses

Note

At no additional cost, Azure DDoS infrastructure protection protects every Azure service that uses public IPv4 and IPv6 addresses. This DDoS protection service helps to protect all Azure services, including platform as a service (PaaS) services such as Azure DNS. For more information on supported PaaS services, see DDoS Protection reference architectures. Azure DDoS infrastructure protection requires no user configuration or application changes. Azure provides continuous protection against DDoS attacks. DDoS protection does not store customer data.

Limitations

DDoS Network Protection and DDoS IP Protection have the following limitations:

  • PaaS services (multi-tenant), which includes Azure App Service Environment for Power Apps, Azure API Management in deployment modes other than APIM with virtual network integration (For more information see https://techcommunity.microsoft.com/t5/azure-network-security-blog/azure-ddos-standard-protection-now-supports-apim-in-vnet/ba-p/3641671), and Azure Virtual WAN aren't currently supported.
  • Protecting a public IP resource attached to a NAT Gateway isn't supported.
  • Virtual machines in Classic/RDFE deployments aren't supported.
  • VPN gateway or Virtual network gateway is protected by a DDoS policy. Adaptive tuning isn't supported at this stage.
  • Partially supported: the Azure DDoS Protection service can protect a public load balancer with a public IP address prefix linked to its frontend. It effectively detects and mitigates DDoS attacks. However, telemetry and logging for the protected public IP addresses within the prefix range are currently unavailable.

DDoS IP Protection is similar to Network Protection, but has the following additional limitation:

  • Public IP Basic tier protection isn't supported.

Note

Scenarios in which a single VM is running behind a public IP is supported, but not recommended. For more information, see Fundamental best practices.
