Falcon SIEM + XDR Deployment

Automated Agent Enforcement and Unified Threat Visibility

Challenge

The company acquired Falcon Next-Gen SIEM with XDR and SOAR capabilities, but deployment and integration were incomplete. My task was to enforce agent installation across all endpoints, connect all logging sources, and use Falcon’s capabilities to harden internal infrastructure.

Tools & Technologies

Implementation

  1. Deployed Falcon agent across all endpoints using GPO with auto-reinstall logic
  2. Created PowerShell script to validate agent presence and enforce compliance
  3. Connected all major data sources to Falcon console: AD, DCs, Entra, M365, Azure, network logs
  4. Enabled Falcon’s XDR and SOAR capabilities for automated threat detection and response
  5. Enforced MFA for internal access to domain controllers using Falcon-integrated identity signals
  6. Validated logging, alerting, and remediation workflows across the SIEM stack
