Support & SLA

  • We provide technical support for all Azure services released to general availability, including VPN Gateway, through Azure Support, starting at $29/month. Billing and subscription management support is provided at no cost.
  • SLA—To learn more about our SLA, please visit the SLA page


  • Resources are counted at the enrollment level. Monthly price for DDoS Protection and overage charges will be billed against the subscription that is associated with the DDoS Protection Plan. Data processing charges will be billed against their corresponding subscriptions.
  • 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). Additional protected resources may be added in the future.
  • Data processing for the above protected resources is egress bandwidth from any VM on the DDoS protected Virtual Network (VNET). The total amount of egress bandwidth across those VMs is aggregated and use for billing purposes. Egress traffic to the Internet is calculated. Traffic within the VNETs, across VNETs or traffic to ExpressRoute or VPN Gateway is not counted. The data processing charge reflects compute and storage resources required to analyze and store application traffic patterns for historical analysis. Data processing charges allow for a pricing model that scales as your application scales or to have lower overall charges for development or test environments that they wish to protect. Data processing charges apply in conjunction with the VM network egress bandwidth charges. Egress charges are additional.
  • If your DDoS Protection service 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 and data transfer overage incurred.
