Capability differences between portals

Most Microsoft Sentinel capabilities are available in both the Azure and Defender portals. In the Defender portal, some Microsoft Sentinel experiences open out to the Azure portal for you to complete a task.

This section covers the Microsoft Sentinel capabilities or integrations in the unified security operations platform that are only available in either the Azure portal or Defender portal or other significant differences between the portals. It excludes the Microsoft Sentinel experiences that open the Azure portal from the Defender portal.

CapabilityAvailabilityDescription
Advanced hunting using bookmarksAzure portal onlyBookmarks aren't supported in the advanced hunting experience in the Microsoft Defender portal. In the Defender portal, they're supported in the Microsoft Sentinel > Threat management > Hunting.

For more information, see Keep track of data during hunting with Microsoft Sentinel.

Attack disruption for SAPDefender portal onlyThis functionality is unavailable in the Azure portal.

For more information, see Automatic attack disruption in the Microsoft Defender portal.

AutomationSome automation procedures are available only in the Azure portal.

Other automation procedures are the same in the Defender and Azure portals, but differ in the Azure portal between workspaces that are onboarded to the unified security operations platform and workspaces that aren't.

For more information, see Automation with the unified security operations platform.

Data connectors: visibility of connectors used by the unified security operations platformAzure portal onlyIn the Defender portal, after you onboard Microsoft Sentinel, the following data connectors that are part of the unified security operations platform aren't shown in the Data connectors page:
  • Microsoft Defender for Cloud Apps
  • Microsoft Defender for Endpoint
  • Microsoft Defender for Identity
  • Microsoft Defender for Office 365 (Preview)
  • Microsoft Defender XDR
  • Subscription-based Microsoft Defender for Cloud (Legacy)
  • Tenant-based Microsoft Defender for Cloud (Preview)

    In the Azure portal, these data connectors are still listed with the installed data connectors in Microsoft Sentinel.

  • Entities: Add entities to threat intelligence from incidentsAzure portal onlyThis functionality is unavailable in the unified security operations platform.

    For more information, see Add entity to threat indicators.

    Fusion: Advanced multistage attack detectionAzure portal onlyThe Fusion analytics rule, which creates incidents based on alert correlations made by the Fusion correlation engine, is disabled when you onboard Microsoft Sentinel to the unified security operations platform.

    The unified security operations platform uses Microsoft Defender XDR's incident-creation and correlation functionalities to replace those of the Fusion engine.

    For more information, see Advanced multistage attack detection in Microsoft Sentinel

    Incidents: Adding alerts to incidents /
    Removing alerts from incidents
    Defender portal onlyAfter onboarding Microsoft Sentinel to the unified security operations platform, you can no longer add alerts to, or remove alerts from, incidents in the Azure portal.

    You can remove an alert from an incident in the Defender portal, but only by linking the alert to another incident (existing or new).

    Incidents: editing commentsAzure portal onlyAfter onboarding Microsoft Sentinel to the unified security operations platform, you can add comments to incidents in either portal, but you can't edit existing comments.

    Edits made to comments in the Azure portal don't synchronize to the unified security operations platform.

    Incidents: Programmatic and manual creation of incidentsAzure portal onlyIncidents created in Microsoft Sentinel through the API, by a Logic App playbook, or manually from the Azure portal, aren't synchronized to the unified security operations platform. These incidents are still supported in the Azure portal and the API.See Create your own incidents manually in Microsoft Sentinel.
    Incidents: Reopening closed incidentsAzure portal onlyIn the unified security operations platform, you can't set alert grouping in Microsoft Sentinel analytics rules to reopen closed incidents if new alerts are added.
    Closed incidents aren't reopened in this case, and new alerts trigger new incidents.
    Incidents: TasksAzure portal onlyTasks are unavailable in the unified security operations platform.

    For more information, see Use tasks to manage incidents in Microsoft Sentinel.

    Multiple workspace management for Microsoft SentinelDefender portal: Limited to one Microsoft Sentinel workspace per tenant

    Azure portal: Centrally manage multiple Microsoft Sentinel workspaces for tenants

    Only one Microsoft Sentinel workspace per tenant is currently supported in the unified security operations platform. So, Microsoft Defender multitenant management supports one Microsoft Sentinel workspace per tenant.

    For more information, see the following articles:
    - Defender portal: Microsoft Defender multitenant management
    - Azure portal: Manage multiple Microsoft Sentinel workspaces with workspace manager
