Want to experience Microsoft 365 Defender? You can evaluate it in a lab environment or run your pilot project in production.

Microsoft 365 Defender is a unified pre- and post-breach enterprise defense suite that natively coordinates detection, prevention, investigation, and response across endpoints, identities, email, and applications to provide integrated protection against sophisticated attacks.

With the integrated Microsoft 365 Defender solution, security professionals can stitch together the threat signals that each of these products receive and determine the full scope and impact of the threat; how it entered the environment, what it’s affected, and how it’s currently impacting the organization. Microsoft 365 Defender takes automatic action to prevent or stop the attack and self-heal affected mailboxes, endpoints, and user identities.

Microsoft 365 Defender protection

Microsoft 365 Defender services protect:

  • Endpoints with Defender for Endpoint – Defender for Endpoint is a unified endpoint platform for preventative protection, post-breach detection, automated investigation, and response.
  • Email and collaboration with Defender for Office 365 – Defender for Office 365 safeguards your organization against malicious threats posed by email messages, links (URLs) and collaboration tools.
  • Identities with Defender for Identity and Azure Active Directory (Azure AD) Identity Protection – Defender for Identity uses your on-premises Active Directory Domain Services (AD DS) signals to identify, detect, and investigate advanced threats, compromised identities, and malicious insider actions directed at your organization. Azure AD Identity Protection automates the detection and remediation of identity-based risks in your cloud-based Azure AD.
  • Applications with Microsoft Defender for Cloud Apps – Microsoft Defender for Cloud Apps is a comprehensive cross-SaaS solution bringing deep visibility, strong data controls, and enhanced threat protection to your cloud apps.

Microsoft 365 Defender’s unique cross-product layer augments the individual service components to:

  • Help protect against attacks and coordinate defensive responses across the services through signal sharing and automated actions.
  • Narrate the full story of the attack across product alerts, behaviors, and context for security teams by joining data on alerts, suspicious events and impacted assets to ‘incidents’.
  • Automate response to compromise by triggering self-healing for impacted assets through automated remediation.
  • Enable security teams to perform detailed and effective threat hunting across endpoint and Office data.

Here’s an example of how the Microsoft 365 Defender portal correlates all related alerts across products into a single incident.

Here’s an example of query-based hunting on top of email and endpoint raw data.

Example of advanced hunting and a query

Microsoft 365 Defender cross-product features include:

  • Cross-product single pane of glass in the Microsoft 365 Defender portal – A central view for all information on detections, impacted assets, automated actions taken, and related evidence in a single queue and a single pane in Microsoft 365 Defender portal.
  • Combined incidents queue – To help security professionals focus on what is critical by ensuring the full attack scope, impacted assets and automated remediation actions are grouped together and surfaced in a timely manner.
  • Automatic response to threats – Critical threat information is shared in real time between the Microsoft 365 Defender products to help stop the progression of an attack.

    For example, if a malicious file is detected on an endpoint protected by Defender for Endpoint, it will instruct Defender for Office 365 to scan and remove the file from all e-mail messages. The file will be blocked on sight by the entire Microsoft 365 security suite.

  • Self-healing for compromised devices, user identities, and mailboxes – Microsoft 365 Defender uses AI-powered automatic actions and playbooks to remediate impacted assets back to a secure state. Microsoft 365 Defender leverages automatic remediation capabilities of the suite products to ensure all impacted assets related to an incident are automatically remediated where possible.
  • Cross-product threat hunting – Security teams can leverage their unique organizational knowledge to hunt for signs of compromise by creating their own custom queries over the raw data collected by the various protection products. Microsoft 365 Defender provides query-based access to 30 days of historic raw signals and alert data across endpoint and Defender for Office 365 data.

Get started

Microsoft 365 Defender licensing requirements must be met before you can enable the service in the Microsoft 365 Defender portal at https://security.microsoft.com For more information, see:

The Microsoft 365 Defender portal

The Microsoft 365 Defender portal combines protection, detection, investigation, and response to emailcollaborationidentitydevice, and app threats, in a central place.

This single pane of glass brings together functionality from existing Microsoft security portals, like the Microsoft 365 Defender portal and the Office 365 Security & Compliance center. The Microsoft 365 Defender portal emphasizes quick access to information, simpler layouts, and bringing related information together for easier use. It includes:

  • Microsoft Defender for Office 365 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 365 Defender is part of Microsoft’s Extended Detection and Response (XDR) solution that leverages the Microsoft 365 security portfolio to automatically analyze threat data across domains, and build a picture of an attack on a single dashboard.
  • 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.

If you need information about what’s changed from the Office 365 Security & Compliance center or the Microsoft 365 Defender portal, see:


The Microsoft 365 Defender portal uses and enforces existing roles-based access, and will move each security model into the unified portal. Each converged workload has its own roles-based access. The roles already in the products will be converged into the Microsoft 365 Defender portal automatically. However, Microsoft Defender for Cloud Apps will still handle its own roles and permissions.

What to expect

All the security content that you use in the Office 365 Security & Compliance Center and the Microsoft 365 security center can now be found in the Microsoft 365 Defender portal.

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
  • Action center
  • Threat analytics

Microsoft 365 Defender emphasizes unity, clarity, and common goals as it merges Microsoft Defender for Office 365 and Microsoft Defender for Endpoint. The merge was based on the priorities listed below, and made without sacrificing the capabilities that each security suite brought to the combination of:

  • Common building blocks
  • Common terminology
  • Common entities
  • Feature parity with other workloads


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.

Unified investigations

Centralizing security information creates a single place for investigating security incidents across Microsoft 365. A primary example is Incidents under Incidents & alerts on the quick launch of Microsoft 365 Defender.

The Incidents page in Microsoft 365 Defender

Selecting an incident name displays a page that demonstrates the value of centralizing security information.

Example of the Summary page for an incident in Microsoft 365 Defender

Along the top of an incident page, you’ll see the SummaryAlertsDevicesUsersMailboxesInvestigationsEvidence and response, and Graph tabs. Select these tabs for more detailed information. For example, the Users tab displays information for users from converged workloads (Microsoft Defender for Endpoint, Microsoft Defender for Identity, and Microsoft Defender for Cloud Apps) and a range of sources such as on-premises Active Directory Domain Services (AD DS), Azure AD, and third-party identity providers. For more information, see investigate users.

Take the time to review the incidents in your environment, drill down into these tabs, and practice building an understanding of how to access the information provided for incidents for different kinds of threats.

For more information, see incidents 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.
