Microsoft Defender for Endpoint

Enrich Harmony asset records with endpoint security posture, vulnerability findings, and threat alerts from Microsoft Defender

Microsoft Defender for Endpoint (MDE) is Microsoft's enterprise endpoint security platform providing threat protection, vulnerability management, and security analytics across Windows, macOS, Linux, iOS, and Android devices. Connecting MDE to Harmony enriches asset records with real-time security posture data - device health, vulnerabilities, and active threat alerts - directly within the Harmony platform.

What the Microsoft Defender for Endpoint Integration Enables

Capability	Description
Device Security Posture	View endpoint health and protection status alongside asset records in Harmony
Vulnerability Findings	Surface vulnerability data per device to prioritize remediation workflows
Threat Alert Enrichment	Pull active alerts into Harmony to drive automated or agent-led incident response
Multi-Tenant Support	Connect multiple MDE instances for multi-tenant environments
Agent Status Monitoring	Track agent states including inactive, outdated, active threats, and scan age
MITRE-Linked Threats	View MITRE ATT&CK-mapped threats surfaced directly from MDE alerts
EDR Provider Visibility	Devices are labeled "Microsoft Defender for Endpoint" as their EDR provider in Harmony

Prerequisites

• Microsoft 365 Defender Access: Account with Security Reader role or higher
• MDE Subscription: Active Microsoft Defender for Endpoint Plan 1 or Plan 2
• Harmony Account: Active Harmony workspace

Connect Microsoft Defender for Endpoint to Harmony

Step 1: Navigate to Integrations

1. Log in to your Harmony dashboard
2. Go to Settings > Integrations
3. Find Microsoft Defender for Endpoint under EDR and click Connect

Step 2: Sign in with Microsoft

1. You will be redirected to Microsoft to authorize the connection
2. Sign in with a Microsoft account that has Security Reader or higher permissions in Microsoft 365 Defender
3. Review the requested permissions and click Accept

Step 3: Authorize and Save

1. Harmony will connect to your Defender tenant
2. Click Save

For multi-tenant MDE environments, you can add multiple instances by repeating this process for each tenant.

What Harmony Syncs

From Microsoft Defender for Endpoint:

• Device inventory (name, OS, platform, onboarding status)
• Device health and sensor health state
• Risk level and exposure level per device
• Active alerts (severity, category, status, affected device)
• Vulnerability findings per device
• Last seen and first seen timestamps
• Agent status - inactive, outdated, active threats, and scan age
• MITRE ATT&CK-linked threat details surfaced from MDE alerts
• EDR provider label ("Microsoft Defender for Endpoint") displayed on each connected device

Use Cases

Security-Enriched Asset Records

View device vulnerability and alert data directly on asset records in Harmony - no need to switch to the Defender portal for context

Automated Threat Response

Trigger Harmony workflows when high-severity alerts are detected, routing incidents to the right team immediately

Vulnerability Prioritization

Use Defender vulnerability data to identify and prioritize devices needing patching or remediation

Compliance Reporting

Generate endpoint security posture reports across the fleet by combining Harmony asset data with MDE findings

Agent Health Monitoring

Track the status of every MDE-managed endpoint in Harmony - identify devices where the agent is inactive, running an outdated version, showing active threats, or has not completed a recent scan. Address coverage gaps before they become exposure risks.

MITRE ATT&CK Threat Visibility

Alerts pulled from MDE include MITRE ATT&CK technique mappings, giving your team immediate context on attacker behavior and helping prioritize investigation and response.
