With 80% of security breaches involving compromised identities, traditional endpoint (EDR) and network (NDR) security are no longer enough. Your hybrid identity infrastructure—especially Active Directory (AD) and Entra ID—must be protected with the same rigor as your devices and networks.

This essential white paper, “Bridging AD Security Gaps with ITDR,” explores how Identity Threat Detection and Response (ITDR) fills the critical security blind spots left by EDR, NDR, and XDR strategies. Learn how Quest Security Guardian enables continuous protection, deeper visibility, and faster response across your identity layer.

What You’ll Learn:

• Why EDR and NDR can’t protect Active Directory from identity-based attacks
• Where Microsoft Defender for Identity (MDI) falls short in Tier 0 protection, GPO awareness, and AD object security
• How ITDR strengthens hybrid AD security posture with real-time drift detection, misconfiguration alerts, and compliance auditing
• Ways to integrate Security Guardian with MDI, Microsoft Sentinel, and Microsoft Security Copilot for a unified, modern defense stack

If you rely on AD or Entra ID, identity isn’t just a risk—it’s a mission-critical priority. This guide gives you the framework and tools to reduce your attack surface and achieve true cyber resilience.
