Microsoft Defender portal

The Microsoft Defender portal at combines protection, detection, investigation, and response to threats across your entire organization and all its components, in a central place. The Defender portal emphasizes quick access to information, simpler layouts, and bringing related information together for easier use. It includes:

  • Microsoft Defender for Office 365 helps organizations secure their enterprise with a set of prevention, detection, investigation and hunting features to protect email, and Office 365 resources.
  • Microsoft Defender for Endpoint delivers preventative protection, post-breach detection, automated investigation, and response for devices in your organization.
  • Microsoft Defender for Identity is a cloud-based security solution that uses your on-premises Active Directory signals to identify, detect, and investigate advanced threats, compromised identities, and malicious insider actions directed at your organization.
  • Microsoft Defender for Cloud Apps is a comprehensive cross-SaaS and PaaS solution bringing deep visibility, strong data controls, and enhanced threat protection to your cloud apps.
  • Microsoft Sentinel is a cloud-native security information and event management (SIEM) solution that provides proactive threat detection, investigation, and response.


Microsoft Sentinel is now generally available within the Microsoft unified security operations platform in the Microsoft Defender portal. For more information, see Microsoft Sentinel in the Microsoft Defender portal.

Watch this short video to learn about the Defender portal.

What to expect

The Microsoft Defender portal helps security teams investigate and respond to attacks by bringing in signals from different workloads into a set of unified experiences for:

  • Incidents & alerts
  • Hunting
  • Actions & submissions
  • Threat analytics
  • Secure score
  • Trials
  • Partner catalog

The Microsoft Defender portal emphasizes unity, clarity, and common goals.


In the Microsoft Defender portal, customers see only the security features their subscription includes. For example, if you have Defender for Office 365 but not Defender for Endpoint, you see features and capabilities for Defender for Office 365, but not for device protection.

Incident and alert investigations

Centralizing security information creates a single place to investigate security incidents across your entire organization and all its components including:

  • Hybrid identities
  • Endpoints
  • Cloud apps
  • Business apps
  • Email and docs
  • IoT
  • Network
  • Business applications
  • Operational technology (OT)
  • Infrastructure and cloud workloads

A primary example is Incidents under Incidents & alerts.

The Incidents page in the Microsoft Defender portal.

Selecting an incident name displays a page that demonstrates the value of centralizing security information as you get better insights into the full extend of a threat, from email, to identity, to endpoints.

Take the time to review the incidents in your environment, drill down into each alert, and practice building an understanding of how to access the information and determine next steps in your analysis.

For more information, see Incidents in the Microsoft Defender portal.


You can build custom detection rules and hunt for specific threats in your environment. Hunting uses a query-based threat hunting tool that lets you proactively inspect events in your organization to locate threat indicators and entities. These rules run automatically to check for, and then respond to, suspected breach activity, misconfigured machines, and other findings.

For more information, see Proactively hunt for threats with advanced hunting in Microsoft Defender XDR.

Improved processes

Common controls and content either appear in the same place, or are condensed into one feed of data making it easier to find. For example, find unified settings under Settings and permissions under Permissions.

Access to Microsoft Defender XDR is configured with Microsoft Entra global roles or by using custom roles.

For Microsoft Sentinel, after you connect Microsoft Sentinel to the Defender portal, your existing Azure role-based access control (RBAC) permissions allow you to work with the Microsoft Sentinel features that you have access to. Continue to manage roles and permissions for your Microsoft Sentinel users from the Azure portal. Any Azure RBAC changes are reflected in the Defender portal. For more information about Microsoft Sentinel permissions, see:

Integrated reports

Reports are also unified in Microsoft Defender XDR. Admins can start with a general security report, and branch into specific reports about endpoints, email & collaboration. The links here are dynamically generated based upon workload configuration.

Quickly view your Microsoft 365 environment

The Home page shows many of the common cards that security teams need. The composition of cards and data is dependent on the user role. Because the Defender portal uses role-based access control, different roles see cards that are more meaningful to their day to day jobs.

This at-a-glance information helps you keep up with the latest activities in your organization. Microsoft Defender XDR brings together signals from different sources to present a holistic view of your Microsoft 365 environment.

You can add and remove different cards depending on your needs.

Search results are categorized by sections related to your search terms. You can search across the following entities in the Microsoft Defender portal:

  • Devices - supported for Defender for Endpoint, Defender for Identity, Defender for Cloud, and Microsoft Sentinel (Preview).

  • Users - supported for Defender for Endpoint, Defender for Identity, Defender for Cloud Apps, and Microsoft Sentinel (Preview).

  • Files, IPs, and URLs - same capabilities as in Defender for Endpoint.


    IP and URL searches are exact match and don't appear in the search results page – they lead directly to the entity page.

  • MDVM - same capabilities as in Defender for Endpoint (vulnerabilities, software, and recommendations).

Search also provides results from relevant links in the Microsoft Tech Community portal, relevant documentation in Microsoft Learn, navigation items within the portal, and a link where you can provide feedback. Search history is stored in your browser and is accessible for the next 30 days.


Notifications are messages that inform you about important events or updates in the Defender portal. They help you stay on top of your security tasks and alerts.

Screenshot of the notifications icon in the Microsoft Defender portal.

Notifications are in the top bar of the portal's user interface. You can access them by clicking on the notification icon, which looks like a bell. A number on the icon indicates that you have that number of unread notifications.

Notifications can tell you about various types of events or updates:

  • Success: when an action or task has been completed successfully like scanning a device or applying a policy.
  • Ongoing: when an action is in progress.
  • Information: when there is some information that you might find useful.
  • Warning: when there is a potential issue or risk that you should be aware of like a device that is out of compliance or a policy that needs to be updated.
  • Error: when there is an error or failure that requires your attention like an incident is deleted or merged, a scan that failed, or a policy that could not be applied.

Each notification has a title and content that provides relevant information about the event or update. Each notification also has a timestamp that shows when the notification was generated.

You can hide notifications from your view. You can dismiss a single notification by clicking on the x icon on the right side of the notification. You can also dismiss all notifications in the list with a single click by using dismiss all at the top of the notification panel.

Dismissing a notification does not delete it from the portal. You can always view your dismissed notifications by selecting show dismissed at the bottom of the notification panel.

Notifications are sorted by their generated time in the notification panel, with the most recent ones displayed first. You can scroll through the list of notifications to see older ones.
