Geographical availability and data residency in Microsoft Sentinel
Article
After your data is collected, stored, and processed, compliance can become an important design requirement, with a significant impact on your Microsoft Sentinel architecture. Having the ability to validate and prove who has access to what data under all conditions is a critical data sovereignty requirement in many countries and regions, and assessing risks and getting insights in Microsoft Sentinel workflows is a priority for many customers.
This article can help you meet compliance requirements by describing where Microsoft Sentinel data is stored.
Collected data
Microsoft Sentinel collects the following types of data:
Raw data, such as event data collected from connected Microsoft services and partner systems. Data from multiple clouds and sources are streamed to the customer’s Azure Log Analytics workspace associated with Microsoft Sentinel, under the customer’s tenant’s subscription. This approach gives the customer the ability to choose region and retention and deletion policies.
Processed data, such as incidents, alerts, and so on.
Configuration data, such as connector settings, rules, and so on.
Data storage location
Data used by the service, including customer data, might be stored and processed in the following locations:
Data type
Location
Raw data
Stored in the same region as the Azure Log Analytics workspace associated with Microsoft Sentinel. For more information, see Supported regions.
Raw data is processed in one of the following locations: - For Log Analytics workspaces located in Europe, customer data is processed in Europe. - For Log Analytics workspaces located in Israel, customer data is processed in Israel. - For Log Analytics workspaces located in any of the China 21Vianet regions, customer data is processed in China 21Vianet. - For workspaces located in any other location, customer data is processed in a US region.
Processed data and configuration data
- For workspaces onboarded to Microsoft's unified security operation's platform, processed data and configuration data might be stored and processed in Microsoft Defender XDR regions. For more information, see Data security and retention in Microsoft Defender XDR.
- For workspaces not onboarded to Microsoft's unified security operations platform, processed data and configuration data is stored and processed using the same methodology as raw data.
