Microsoft Defender for Cloud provides advanced threat detection capabilities across your cloud workloads. This includes comprehensive coverage plans for compute, PaaS and data resources in your environment. Before enabling Defender for Cloud across subscriptions, customers are often interested in having a cost estimation to make sure the cost aligns with the team’s budget. We previously released the Microsoft Defender for Storage Price Estimation Workbook, which was widely and positively received by customers. Based on customer feedback, we have extended this offering by creating one comprehensive workbook that covers most Microsoft Defender for Cloud plans. This includes Defender for Key Vault, Containers, App Service, Servers, Storage and Databases.
This price estimation workbook is out-of-the box and can be found in the Defender for Cloud portal.
After reading this blog and using the workbook, be sure to leave your feedback to be considered for future enhancements. Please remember these numbers are only estimated based on retail prices and do not provide actual billing data. For reference on how these prices are calculated, visit the Pricing—Microsoft Defender | Microsoft Azure.
When first opening the workbook, an overview page is shown that displays your overall Microsoft Defender for Cloud coverage across all selected subscriptions. The coverage is represented through the green and gray “on/off” tabs. If the plan is enabled on that subscription, the tab shows green. If the plan is not enabled, the tab shows gray. When clicking on “on/off” in this table, you will be redirected to a subscription’s Defender for Cloud plans page from where you can directly enable additional plans.
Defender for App Service
This table considers all App Services with and without Microsoft Defender for App Services enabled across your selected subscription. It is based on the retail price of $15 USD per App Service worker node per month.
Defender for Containers
The Defender for Containers blade shows price estimations for two different environments: Azure Kubernetes Services (AKS) clusters, and Azure Arc-enabled Kubernetes clusters. For AKS, price estimation is calculated based on the average number of worker nodes in this cluster during the past 30 days. Defender for Containers pricing is based on the average number of vCores used in a cluster so based on the average number of nodes and the VM size, we can calculate a valid price estimation. In case the workbook cannot access telemetry for average node numbers, the table will show a price estimation based on the current number of vCores used in the AKS cluster.
For Azure Arc-enabled Kubernetes clusters, price estimation is based on the number of vCores that are configured in this cluster. Both tables will also show the number of container images that can be scanned at no additional cost based on the number of vCores used in both, AKS and Azure Arc-enabled Kubernetes clusters.
Defender for Databases
The Defender for Databases dashboard covers three key environments: Defender for SQL on Azure SQL Databases, Defender for SQL servers on machines and Open-source relational databases.
All estimations are based on the retail price of $15 USD per resource per month. “Defender for SQL on Azure SQL databases” includes Azure SQL Database's Single databases and Elastic pools, Azure SQL Managed Instances and Azure Synapse (formerly SQL DW). “Defender for SQL servers on machines” includes all SQL servers on Azure Virtual Machines. Lastly, “Open-source relational databases” looks at Azure Database for PostgreSQL, Azure Database for MySQL single server and Azure Database for MariaDB single server. The logic and calculation for all three environments are the same. On the backend, the workbook runs a query to find all SQL or database resources in the selected environment and multiplies each one by 15 to get the estimated monthly cost.
Defender for Key Vault
The Defender for Key Vault dashboard considers all Key Vaults with or without Defender for Key Vault enabled on the selected subscriptions. The calculations are based on the retail price of $0.02 USD per 10k transactions. The “Estimated Cost (7 days)” column takes the total Key Vault transactions of the last 7 days, divides them by 10K and multiples them by 0.02. In “Estimated Monthly Price”, the results of “Estimated Cost (7 days)” are multiplied by 4.35 to get the monthly estimate.
Defender for Servers
The Defender for Servers dashboard considers all servers on your subscriptions with or without Defender for Servers enabled. This dashboard includes estimations for Azure and hybrid servers connected through Azure Arc. The estimation is based on the retail price of $0.02 USD per server per hour. This dashboard includes the option to select a Log Analytics Workspaces. By selecting a workspace, the workbook can retrieve historical data for how many hours the machine has been running in the past seven days. If there is no historical data for the machine, the workbook assumes the machine has been running for 24hrs in the past 7 days. The column “Weekly Runtime” presents the total number of running hours from the past 7 days using the aforementioned strategies. The column “Estimated Cost (7 days)" takes the weekly hours and multiplies them by .02. Finally, in “Estimated Monthly Cost”, the result from “Estimated Cost (7 days)” is multiplied by * 4.35 to give the estimated monthly cost.
Defender for Storage
The Defender for Storage workbook looks at historical file and blob transaction data on supported storage types such as Blob Storage, Azure Files and Azure Data Lake Storage Gen 2. To learn more about the storage workbook, visit Microsoft Defender for Storage – Price Estimation Dashboard - Microsoft Tech Community.
Azure Monitor Metrics data backends have limits and the number of requests to fetch data might time out. To solve this, narrow your scope by reducing the selected subscriptions or resource types.
