Entra Hybrid joined with Microsoft Defender for Endpoint

Entra Hybrid Join with Microsoft Defender for Endpoint

Section titled “Entra Hybrid Join with Microsoft Defender for Endpoint”

This guide outlines my approach to onboarding Active Directory (AD) devices to Microsoft Defender for Endpoint. As an integrator, my focus is on simplifying the process of integrating security solutions, ensuring organizations can efficiently secure their endpoints while minimizing complexity.

Endpoint security is a top concern for organizations today, especially as cyber threats continue to evolve. Microsoft Defender for Endpoint provides an advanced layer of protection, detecting, investigating, and responding to potential security risks. The integration of Microsoft Entra ID, Intune, and Defender for Endpoint allows organizations to manage their AD-joined devices seamlessly while enhancing security.


Before diving into the integration process, ensure that the following prerequisites are in place:

PrerequisiteRequirementBusiness Impact
Defender for Endpoint SubscriptionActive Microsoft Defender for Endpoint subscriptionEssential for endpoint protection
Entra Connect UnderstandingSolid understanding of Microsoft Entra ConnectRequired for device and user synchronization
Intune MDM SetupIntune configured as Mobile Device Management solutionCentralized device management
Administrative AccessAdmin access to configure necessary servicesAbility to implement required configurations

These prerequisites create a strong foundation for a smooth implementation.


To manage AD-joined devices efficiently, they need to be joined to Microsoft Entra ID and Intune as hybrid devices. This integration ensures that devices are registered in the cloud and ready for policy management.

If you don’t already have Microsoft Entra Connect installed and configured, you’ll need to set it up before proceeding with the device joining process. This step involves synchronizing your on-premises Active Directory with Microsoft Entra ID.

Note: I will cover the Entra Connect setup process in a separate blog post for further details.

Once Entra Connect is in place, the process becomes automated. Devices will automatically register with Microsoft Entra ID and Intune upon user login. By automating this step, organizations reduce the complexity of manual enrollment.

ProcessAutomationBenefit
Device RegistrationAutomatic upon user loginReduced manual intervention
Policy ApplicationSeamless through IntuneImmediate security enforcement

Once devices are enrolled in Microsoft Entra ID and Intune, the next step is to onboard them to Microsoft Defender for Endpoint. This allows the organization to start collecting security data and applying protection policies.

The onboarding process should be seamless. By connecting Intune to Defender for Endpoint, devices are automatically onboarded without manual intervention, ensuring that security is applied as soon as possible.


Before implementing a new EDR solution, it’s essential to remove any old ones to avoid conflicts. As part of the integration process, I always recommend removing previous solutions to ensure that Microsoft Defender for Endpoint operates without interference.

A centralized, automated removal process through Intune or a PowerShell script can simplify this task and save time.

Fine-Tuning Defender for Endpoint through Intune

Section titled “Fine-Tuning Defender for Endpoint through Intune”

Once the devices are onboarded, it’s essential to configure Microsoft Defender for Endpoint through Intune to ensure comprehensive security. This involves customizing security policies and enforcing settings tailored to your organization’s needs.

In addition to the basic configurations, Microsoft’s security baselines provide a comprehensive set of policies designed by Microsoft experts to secure endpoints. These baselines contain over 300 built-in rules that can be easily applied.

Key Insight: If these baselines are effective for Microsoft, they are certainly a solid choice for securing your devices as well.

Policy AreaConfigurationBusiness Value
BitLocker PoliciesEncrypt all device drives with secure key storageProtection of sensitive data
Windows Update PoliciesImplement strict update policies for latest patchesReduced vulnerability exposure
Secure Browser PoliciesEnforce secure browser configurationsMitigation of web-based threats
Compliance PoliciesDefine acceptable security posture for devicesEnsured device compliance standards

These policies encrypt all device drives to protect sensitive data. We also ensure that the encryption keys are securely stored in device input objects, ensuring data remains safe even if the device is lost or compromised.

Implementing strict update policies ensures devices are always up-to-date with the latest security patches. Keeping devices patched reduces vulnerabilities and strengthens defenses against known threats.

Secure browser configurations help mitigate web-based threats like phishing and malware. By enforcing these policies, organizations can minimize risks related to online activities.

Compliance policies define the acceptable security posture for devices. By evaluating devices against these policies, we ensure they meet the organization’s security standards. Devices that don’t comply with the set requirements can be blocked from accessing corporate resources until the issue is resolved.


The goal is to simplify the process of securing Active Directory devices while ensuring robust protection against threats. By integrating Microsoft Entra ID, Intune, and Microsoft Defender for Endpoint, organizations can streamline their security operations and ensure that all devices are managed centrally.

BenefitCapabilityImpact
Centralized ManagementSingle platform for device securitySimplified administration
Automated ProcessesReduced manual interventionIncreased efficiency
Enhanced SecurityComprehensive endpoint protectionImproved threat defense

The process is automated and efficient, minimizing the need for manual intervention while maximizing security.

Key Takeaway: By following these steps, organizations can stay ahead of emerging threats and maintain a strong security posture without overcomplicating their workflows.
