Microsoft’s Defender External Attack Surface Management (DefenderEASM) now integrates with Exposure Management, providing deeper insights into external threats. This integration allows security teams to assess exposure types, track security metrics, and visualize attack surfaces for better risk mitigation.
🔍 Key Features:
- Security Metrics Dashboard – Review exposure types (e.g., open ports, vulnerable services) from EASM assessments.
- Attack Surface Mapping – Search and analyze exposed assets (IPs, domains, hosts).
- DefenderEASM Integration – Automatically pull threat intelligence into Exposure Management.

You Should Know: Practical DefenderEASM & Exposure Management Commands
1. Check Exposed Assets via PowerShell
Fetch exposed assets from DefenderEASM Get-EasmAsset -Type "Domain" -Status "Exposed" | Format-Table -AutoSize List vulnerable services Get-EasmFinding -Severity "High" | Select-Object Asset, Vulnerability, RiskScore
2. Linux-Based Attack Surface Scanning
Use Nmap to verify exposed ports (simulating EASM scans) nmap -sV --script vuln <TARGET_IP> -oN scan_results.txt Check DNS exposures with Dig dig +short A example.com
3. Windows Defender for Exposure Analysis
Export Defender EASM findings to CSV Export-EasmDiscovery -Path "C:\Reports\ExposedAssets.csv" Monitor new exposures in real-time Start-EasmMonitoring -AlertType "NewExposure" -Action "Notify"
4. Automating Exposure Reports
Cron job to scan and log exposures daily 0 2 /usr/bin/nmap -sV --top-ports 1000 <TARGET_NETWORK> >> /var/log/easm_scan.log
What Undercode Say
Microsoft’s DefenderEASM integration with Exposure Management is a game-changer for proactive threat hunting. By leveraging automated scans, PowerShell cmdlets, and Linux-based tools like Nmap, security teams can:
– Detect misconfigurations before attackers exploit them.
– Map attack surfaces dynamically.
– Prioritize remediation based on real-time risk scores.

Expected Output:
Exposed Assets Report: - IP: 192.168.1.1 | Service: HTTP (Port 80) | Risk: Medium - Domain: example.com | Expiry: 2025-12-01 | Risk: High
Prediction
As cloud and hybrid infrastructures grow, expect tighter integration between EASM and SIEM tools, enabling AI-driven exposure predictions and automated patching.
