Microsoft Defender for Business vs Defender for Endpoint

Some users may also hear of Microsoft Defender for Business. Learn the key differences between Microsoft Defender for Business and Defender for Endpoint below:

Note: There is also a Defender for Endpoint Plan 1, which provides basic protection (AV and Attack Surface Reduction) but lacks the advanced EDR and automation found in both MDB and MDE Plan 2.

💡Summary:

• Defender for Business: Best for teams without a dedicated security operations center—offers guided setup, default policies, and simplified administration.
• Defender for Endpoint: Designed for enterprise teams—provides deep visibility, advanced threat hunting, custom alerts, and granular integrations.

How to Set Up Microsoft Defender for Endpoint Step by Step

Setting up Microsoft Defender for Endpoint correctly ensures your organization gets full protection from ransomware, zero-day exploits, and advanced threats. Below is a clear deployment guide:

Step 1 - Prepare for deployment

Before starting, ensure your environment meets the necessary prerequisites.

• Licensing: Verify you have a valid license, such as Microsoft 365 E3/E5, Windows 10/11 Enterprise E3/E5, or a standalone Defender for Endpoint P1/P2.
• System Requirements: Ensure devices are running supported operating systems (Windows 10/11, macOS, Linux, Android, or iOS).
• Permissions: You must have Global Administrator or Security Administrator roles to configure the tenant.

Step 2 - Connect Defender to Microsoft Intune

If you use Microsoft Intune for device management, you must enable the service-to-service connection.

In the Microsoft Defender Portal:

1. Navigate to Settings > Endpoints > Advanced features.

2. Locate Microsoft Intune connection and toggle it to On.

3. Click Save preferences.

In the Microsoft Intune Admin Center:

1. Go to Endpoint security > Microsoft Defender for Endpoint.

2. Set Allow Microsoft Defender for Endpoint to enforce Endpoint Security Configurations to On.

3. Click Save at the top of the page.

Step 3 - Onboard Devices

Onboarding activates the Defender sensor on your endpoints so they can report data to the portal.

Using Intune (Recommended for Scale):

1. Go to Endpoint security > Endpoint detection and response.

2. Select Create Policy, choose your platform (e.g., Windows 10 and later), and select the Endpoint detection and response profile.

3. Set the configuration package type to Auto from connector and assign the policy to your device groups.

Using Local Script (For Testing/Small Scale):

1. In theDefender Portal, go to Settings > Endpoints > Device management > Onboarding.

2. Select the OS and choose Local script as the deployment method.

3. Download the onboarding package, extract it, and run the script on the target device as an administrator.

Step 4 - Configure Security Capabilities

Once devices are onboarded, enable core protection features to secure them.

1. Next-Generation Protection (Antivirus):

Create an Antivirus policy in Intune (Endpoint security > Antivirus) to enable Real-time protection and Cloud-delivered protection.

2. Attack Surface Reduction (ASR):

Set up ASR rules in Intune to block common malware entry points, such as malicious office macros or credential stealing.

3. Tamper Protection:

In the Defender Portal (Settings > Endpoints > Advanced features), ensure Tamper Protection is turned On to prevent users or malware from disabling security settings.

Step 5 – Verification

1. Check Device Inventory:

Within 15–30 minutes of onboarding, devices should appear in the Microsoft Defender Portal under Assets > Devices.

2. Run a Detection Test:

On a Windows device, run a specialized command-line script provided by Microsoft to trigger a safe test alert and confirm the sensor is communicating correctly.
