Microsoft Secure Score
Want to experience Microsoft 365 Defender? Learn more about how you can evaluate and pilot Microsoft 365 Defender.
Microsoft Secure Score is a measurement of an organization's security posture, with a higher number indicating more recommended actions taken. It can be found at Microsoft Secure Score in the Microsoft 365 Defender portal.
Following the Secure Score recommendations can protect your organization from threats. From a centralized dashboard in the Microsoft 365 Defender portal, organizations can monitor and work on the security of their Microsoft 365 identities, apps, and devices.
Secure Score helps organizations:
- Report on the current state of the organization's security posture.
- Improve their security posture by providing discoverability, visibility, guidance, and control.
- Compare with benchmarks and establish key performance indicators (KPIs).
Watch this video for a quick overview of Secure score.
Organizations gain access to robust visualizations of metrics and trends, integration with other Microsoft products, score comparison with similar organizations, and much more. The score can also reflect when third-party solutions have addressed recommended actions.
Currently, the Azure Active Directory related Microsoft Secure Score recommendations are not available for customer tenants registered in the following Azure Active Directory regions: Japan, Australia, New Zealand, Fiji, Canada, United Kingdom, South Korea, France, United Arab Emirates, South America, Switzerland, Liechtenstein, Norway, Germany, Brazil, Sweden, and Qatar.
How it works
You're given points for the following actions:
- Configuring recommended security features
- Doing security-related tasks
- Addressing the recommended action with a third-party application or software, or an alternate mitigation
Some recommended actions only give points when fully completed. Some give partial points if they're completed for some devices or users. If you can't or don't want to enact one of the recommended actions, you can choose to accept the risk or remaining risk.
If you have a license for one of the supported Microsoft products, then you'll see recommendations for those products. We show you the full set of possible recommendations for a product, regardless of license edition, subscription, or plan. This way, you can understand security best practices and improve your score. Your absolute security posture, represented by Secure Score, stays the same no matter what licenses your organization owns for a specific product. Keep in mind that security should be balanced with usability, and not every recommendation can work for your environment.
Your score is updated in real time to reflect the information presented in the visualizations and recommended action pages. Secure Score also syncs daily to receive system data about your achieved points for each action.
For Microsoft Teams and AAD related recommendations, the recommendation state will get updated when changes occur in the configuration state. In addition, the recommendation state is refreshed once a month or once a week, respectively.

How recommended actions are scored
Each recommended action is worth 10 points or less, and most are scored in a binary fashion. If you implement the recommended action, like create a new policy or turn on a specific setting, you get 100% of the points. For other recommended actions, points are given as a percentage of the total configuration.
For example, a recommended action states you get 10 points by protecting all your users with multi-factor authentication. You only have 50 of 100 total users protected, so you'd get a partial score of 5 points (50 protected / 100 total * 10 max pts = 5 pts).
Products included in Secure Score
Currently there are recommendations for the following products:
- App governance
- Azure Active Directory
- Citrix ShareFile
- Microsoft Defender for Endpoint
- Microsoft Defender for Identity
- Microsoft Defender for Office
- Exchange Online
- Microsoft Defender for Cloud Apps
- Microsoft Information Protection
- Microsoft Teams
- SharePoint Online
Recommendations for other security products are coming soon. The recommendations won't cover all the attack surfaces associated with each product, but they're a good baseline. You can also mark the recommended actions as covered by a third party or alternate mitigation.
Microsoft Secure Score has updated recommended actions to support security defaults in Azure Active Directory, which make it easier to help protect your organization with pre-configured security settings for common attacks.
If you turn on security defaults, you'll be awarded full points for the following recommended actions:
- Ensure all users can complete multi-factor authentication for secure access (9 points)
- Require MFA for administrative roles (10 points)
- Enable policy to block legacy authentication (7 points)
Security defaults include security features that provide similar security to the "sign-in risk policy" and "user risk policy" recommended actions. Instead of setting up these policies on top of the security defaults, we recommend updating their statuses to "Resolved through alternative mitigation."
Secure Score permissions
Manage permissions with Microsoft 365 Defender Unified role-based access control(RBAC)
With Microsoft 365 Defender Unified role-based access control(RBAC), you can create custom roles with specific permissions for Secure Score. This allows you to control which users have access to Secure Score data, the products for which they will see Secure Score data (for example, Microsoft Defender for Endpoint) and their permission level to the data.
You can also manage user permissions to access Secure Score data from additional data sources, such as the other products supported by Secure Score, for more information, see Products included in Secure Score. You can view the Secure Score data from the additional data sources either alone or alongside the other data sources.
To start using Microsoft 365 Defender Unified RBAC to manage your Secure Score permissions, see Microsoft 365 Defender Unified role-based access control(RBAC).
Currently, the model is only supported in the Microsoft 365 Defender portal. If you want to use GraphAPI (for example, for internal dashboards or Defender for Identity Secure Score) you should continue to use Azure Active Directory roles. Support GraphAPI is planned at a later date.
Azure Active Directory global roles permissions
Azure Active Directory global roles (for example, Global Administrator) can still be used to access Secure Score. Users who have the supported Azure Active Directory global roles, but are not assigned to a custom role in Microsoft 365 Defender Unified RBAC, will continue to have access to view (and manage where permitted) Secure Score data as outlined below:
The following roles have read and write access and can make changes, directly interact with Secure Score, and can assign read-only access to other users:
- Global administrator
- Security administrator
- Exchange administrator
- SharePoint administrator
The following roles have read-only access and aren't able to edit status or notes for a recommended action, edit score zones, or edit custom comparisons:
- Helpdesk administrator
- User administrator
- Service support administrator
- Security reader
- Security operator
- Global reader
If you want to follow the principle of least privilege access (where you only give users and groups the permissions, they need to do their job), Microsoft recommends that you remove any existing elevated Azure Active Directory global roles for users and/or security groups assigned a custom role with Secure Score permissions. This will ensure that the custom Microsoft 365 Defender Unified RBAC roles will take effect.
Microsoft Secure Score is a numerical summary of your security posture based on system configurations, user behavior, and other security-related measurements. It isn't an absolute measurement of how likely your system or data will be breached. Rather, it represents the extent to which you have adopted security controls in your Microsoft environment that can help offset the risk of being breached. No online service is immune from security breaches, and secure score shouldn't be interpreted as a guarantee against security breach in any manner.
