What to expect

The Microsoft 365 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
  • Learning hub
  • Trials
  • Partner catalog

Microsoft 365 Defender emphasizes unity, clarity, and common goals.


The Microsoft 365 Defender portal is accessible without any need for customers to take migration steps or purchase a new license. For example, this new portal is accessible to administrators with an E3 subscription, just as it is to those with Microsoft Defender for Office 365 Plan 1 and Plan 2; however, Exchange Online Protection, or Defender for Office 365 Plan 1 customers see only the security features their subscription license supports. The goal of the portal is to centralize security.

Incident and alert investigations

Centralizing security information creates a single place for investigating security incidents across Microsoft 365. A primary example is Incidents under Incidents & alerts.

The Incidents page in the Microsoft 365 Defender portal.

Selecting an incident name displays a page that demonstrates the value of centralizing security information as you'll have 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 Microsoft 365 Defender.


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 365 Defender.

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, unified settings.
