The unified Microsoft 365 security center overview
The improved Microsoft 365 security center is now available. This new experience brings Defender for Endpoint, Defender for Office 365, Microsoft 365 Defender, and more into the Microsoft 365 security center. Learn what's new.
The improved Microsoft 365 security center (https://security.microsoft.com) combines protection, detection, investigation, and response to email, collaboration, identity, and device threats, in a central portal.
Microsoft 365 security center brings together functionality from existing Microsoft security portals, like Microsoft Defender Security Center and the Office 365 Security & Compliance center. The security center emphasizes quick access to information, simpler layouts, and bringing related information together for easier use. This center 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.
If you need information about what's changed from the Office 365 Security & Compliance center or the Microsoft Defender Security Center, see:

What to expect
All the security content that you use in the Office 365 Security and Compliance Center (protection.office.com) and the Microsoft Defender security center (securitycenter.microsoft.com) can now be found in the Microsoft 365 security center.
Microsoft 365 security center helps security teams investigate and respond to attacks by bringing in signals from different workloads into a set of unified experiences for:
- Incidents & alerts
- Action Center
- Threat analytics
The Microsoft 365 security center 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
Converging security centers creates a single place for investigating security incidents across Microsoft 365. A primary example is Incidents under Incidents & alerts on the quick launch of the Microsoft 365 security center.
Selecting an incident name displays a page that demonstrates the value of converging security centers.
Along the top of an incident page, you'll see the Summary, Alerts, Devices, Users, Mailboxes, Investigations, and Evidence 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 Cloud App Security) and a range of sources such as on-premises Active Directory Domain Services (AD DS), Azure Active Directory (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 the Microsoft 365 security center.
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.
Permissions & roles
Access the Microsoft 365 security center is configured with Azure Active Directory global roles or by using custom roles. For Defender for Endpoint, see Assign user access to Microsoft Defender Security Center. For Defender for Office 365, see Permissions in the Microsoft 365 compliance center and Microsoft 365 security center.

Microsoft Defender for Endpoint in the Microsoft 365 security center supports granting access to managed security service providers (MSSPs) in the same that way access is granted in the Microsoft Defender security center.
Reports are also unified in the Microsoft 365 security center. 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 Microsoft 365 security center uses role-based access control, different roles will 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. The Microsoft 365 security center brings together signals from different sources to present a holistic view of your Microsoft 365 environment.
The cards fall into these categories:
- Identities- Monitor the identities in your organization and keep track of suspicious or risky behaviors. Learn more about identity protection.
- Data - Help track user activity that could lead to unauthorized data disclosure.
- Devices - Get up-to-date information on alerts, breach activity, and other threats on your devices.
- Apps - Gain insight into how cloud apps are being used in your organization. Learn more about Cloud App Security discovered apps.
Threat analytics with better data coverage
Track and respond to emerging threats with the following Microsoft 365 Defender threat analytics integrated experience:
- Better data coverage between Microsoft Defender for Endpoint and Microsoft Defender for Office 365, making combined incident management, automatic investigation, remediation, and proactive or reactive threat hunting across-domain possible.
- Email-related detections and mitigations from Microsoft Defender for Office 365, in addition to the endpoint data already available from Microsoft Defender for Endpoint.
- A view of threat-related incidents which aggregate alerts into end-to-end attack stories across Microsoft Defender for Endpoint and Microsoft Defender for Office 365 to reduce the work queue, as well as simplify and speed up your investigation.
- Attack attempts detected and blocked by Microsoft 365 Defender solutions. There's also data that you can use to drive preventive actions that mitigate the risk of further exposure and increase resilience.
- Enhanced design that puts actionable information in the spotlight to help you quickly identify data to urgently focus on, investigate, and leverage from the reports.
A centralized Learning Hub
The Microsoft 365 security center includes a learning hub that bubbles up official guidance from resources such as the Microsoft security blog, the Microsoft security community on YouTube, and the official documentation at docs.microsoft.com.
Inside the learning hub, Email & Collaboration (Microsoft Defender for Office 365 or MDO) guidance is side-by-side with Endpoint (Microsoft Defender for Endpoint or MDE), and Microsoft 365 Defender learning resources.
The learning hub opens with Learning paths organized around topics such as “How to Investigate Using Microsoft 365 Defender?” and “Microsoft Defender for Office 365 Best Practices”. This section is currently curated by the security Product Group inside Microsoft. Each Learning path reflects a projected time it takes to get through the concepts. For example 'Steps to take when a Microsoft Defender for Office 365 user account is compromised' is projected to take 8 minutes, and is valuable learning on the fly.
After clicking through to the content, it may be useful to bookmark this site and organize bookmarks into a 'Security' or 'Critical' folder. To see all Learning paths, click the Show all link in the main panel.
There are helpful filters along the top of the Microsoft 365 security center learning hub that will let you choose between products (currently Microsoft 365 Defender, Microsoft Defender for Endpoint, and Microsoft Defender for Office 365). Notice that the number of learning resources for each section is listed, which can help learners keep track of how many resources they have at hand for training and learning.
Along with the Product filter, current topics, types of resources (from videos to webinars), levels of familiarity or experience with security areas, security roles, and product features are listed.
