Azure DDoS Protection pricing

Protect your Azure resources from distributed denial-of-service (DDoS) attacks

Azure DDoS Protection enables you to protect your Azure resources from distributed denial of service (DDoS) attacks with always-on monitoring and automatic network attack mitigation. There is no upfront commitment, and your total cost scales with your cloud deployment.

Azure DDoS Protection offers two tiers – IP Protection and Network Protection – to meet your security and cost needs.

Prices are estimates only and are not intended as actual price quotes.

Network Protection will have a fixed monthly charge, which includes protection for 100 public IP resources. Protection for additional public IP resources will be charged on a monthly per-resource basis. A single Azure DDoS Protection plan in a tenant can be used across multiple subscriptions.

Price
Monthly charge (includes protection for 100 public IP resources) $2944/month
Overage charges (more than 100 public IP resources) $29.5 per resource per month

Network Protection is enabled at the virtual network (VNet) level. All protected resource types within the virtual network will be automatically protected when Network Protection is enabled on the virtual network. When Azure Application Gateway with WAF is deployed in a protected virtual network, there are no additional charges for WAF - you pay for the Application Gateway at the lower non-WAF rate.

If the resource is protected with Network Protection, any scale out costs during a DDoS attack are covered and customer will get the cost credit back for those scaled out resources.

Examples of resources:

  • Data process (ingress/egress) for Azure Firewall, Application Gateway with WAF
  • Scale out of Virtual Machines and Azure Kuberentes Service
  • Data egress for network bandwidth-happens during an amplification attack when DDoS impacted app makes outbound connections.
  • Scale out of backend PaaS resources like SQL, CosmosDB, Storage, App Services etc.

Pricing Examples

Example 1 Network Protection plan in a single subscription and multiple VNets

Let's assume you have only 1 subscription in your tenant. You create a Network Protection plan in that subscription. That subscription will be billed $2944/month. Now the same Network Protection plan can be linked to any number of VNets in that subscription to the same plan.

Total monthly bill for the Network Protection plan will be $2944/month = $2944/month.

Example 2 Network Protection plan across the tenant (multiple subscriptions) and multiple VNets

Let's assume you have 10 subscriptions in your tenant. You create a Network Protection plan in subscription # 1. The subscription # 1 will be billed $2944/month. The same plan can now be linked to any VNet across all your 10 subscriptions and across different regions.

Total monthly bill for a Network Protection plan will be $2944/month = $2944/month.

Example 3 Network Protection plan across the tenant (multiple subscriptions) and multiple VNets with more than 100 Public IPs

Let's assume you have 10 subscriptions in your tenant. You create a Networking Protection plan in subscription # 1. The subscription # 1 will be billed $2944/month. The same plan can now be linked to any VNet across all your 10 subscriptions and across different regions. Let's assume that there are total 110 public IPs that are protected by Network Protection. For each public IP above 100, there's a $29.5 per resource per month charge.

Total monthly bill for Network Protection plan will be $2944/month + $295 ($29.5 per additional resource per month (10 public IPs above 100)) = $3238/month.

Example 4 Network Protection plan with Azure Web Application Firewall (WAF) with Azure Application Gateway

Let's assume you deploy an Azure Application Gateway with Azure Web Application Firewall (WAF) in a VNet protected by Network Protection. In this scenario, you will be charged the base pricing for your Application Gateway, instead of the higher tier of Application Gateway with WAF pricing. This means that there is no extra charge for the WAF usage. This discount applies to both Application Gateway WAF and WAF_v2 SKUs.

For example, if you are not using Network Protection and deploy an Application Gateway WAF_v2, you are charged $0.558 per gateway-hour. If you deploy the same resource type (Application Gateway WAF_v2) and you are using Network Protection to protect that VNet, you will be charged the standard Application Gateway price of $0.31 per gateway-hour.

IP Protection is used to protect an individual public IP resource and will have a fixed monthly charge per public IP resource protected.

Price 1
Monthly charge per public IP resource protected $199/month
1 Billing for IP Protection will be effective starting March 1, 2023. Price is based on 730 hours per month.

  • If you need to protect less than 15 public IP resources, the IP Protection tier is the more cost-effective option. If you have more than 15 public IP resources to protect, then the Network Protection tier is more cost-effective. Network Protection also offers additional features, including DDoS Protection Rapid Response (DRR), cost protection guarantees, and Web Application Firewall (WAF) discounts.
  • Resources are counted at the enrollment level. Monthly price for Azure DDoS Protection will be billed against the subscription that is associated with the protection plan.
  • A resource is a Public IP attached to an IaaS VM, Load Balancer (Classic & Standard Load Balancers), Application Gateway (including WAF) cluster, Service Fabric or an IaaS based Network Virtual Appliance (NVA). Protection also covers public IP ranges brought to Azure via custom IP prefixes (BYOIPs). Additional protected resources may be added in the future.
  • If your Azure DDoS Protection plan is active for the entire month, you will be charged the monthly fee regardless of usage. However, if your service was active only for a portion of the month, you would only receive a prorated bill for the hours used.
