Question details

A 30-person organization needs to deploy Microsoft Defender for Endpoint Plan 2 on unmanaged devices without Intune or Entra ID Premium.

Product: Microsoft Defender for Endpoint
Device & OS: Windows and Mac
Scenario: Remote users working on unmanaged devices with Microsoft 365 A3 licenses, requiring a scalable security deployment method.
Observed behavior: Seeking a viable deployment strategy because manual local onboarding scripts are not recommended by Microsoft for environments with more than 10 devices.

Before you start

Before exploring deployment alternatives, verify that your Microsoft 365 A3 licenses are properly assigned to all users and that you have global administrative access to your Microsoft 365 tenant.

Solution 1Recommended

Consult the Microsoft Defender Community Hub

Since your environment lacks Intune or Entra ID Premium and exceeds the 10-device limit for manual local scripts, consulting Microsoft specialists is the most reliable way to find a tailored onboarding method.

Microsoft provides dedicated forums where deployment specialists and engineers assist with edge-case scenarios, such as managing security on mixed OS unmanaged devices.

Navigate to the Community Hub

Open your web browser and go to the official Microsoft Tech Community website.

Locate the specific forum

Search for and enter the 'Microsoft Defender for Endpoint' section within the community hubs.

Post your scenario

Create a new discussion thread detailing your specific situation: 30 unmanaged Windows and Mac devices, M365 A3 licenses, and the lack of Microsoft Intune or Entra ID Premium, asking for specialized onboarding guidance.

Alternative Management Tools: Community experts may suggest utilizing a third-party Mobile Device Management (MDM) solution if Intune is not an option for your organization.

Frequently Asked Questions

Can I use a local script to onboard Microsoft Defender for Endpoint on more than 10 devices?

Microsoft officially recommends using local onboarding scripts for up to 10 devices only. For larger deployments, management tools like Intune or Microsoft Endpoint Configuration Manager are advised. While you technically can run the script manually on more devices, it becomes difficult to manage and update.

Do I absolutely need Microsoft Intune to deploy Defender for Endpoint?

No. While Intune is Microsoft's recommended tool for managing and deploying Defender, you can also use third-party Mobile Device Management (MDM) solutions, Group Policy (for domain-joined devices), or Endpoint Configuration Manager.

Are unmanaged Mac devices supported by Microsoft Defender for Endpoint?

Yes, Microsoft Defender for Endpoint supports macOS. However, deploying it to unmanaged Macs requires users to manually install the package and grant the necessary system permissions, or it requires an MDM solution to automate the permissions and deployment.
