Zero-trust security architecture integrating Microsoft Entra ID, Intune, and Defender across corporate, mobile, and IoT devices. Users authenticate via Entra ID with conditional access policies, while corporate, mobile, and IoT endpoints enroll in Intune for compliance and app protection enforcement. Microsoft Defender for Endpoint monitors device threats, feeding telemetry to Microsoft Sentinel and Log Analytics for unified threat detection and compliance reporting. This architecture demonstrates Microsoft's defense-in-depth approach, combining identity governance, device management, and threat intelligence to reduce attack surface and enforce least-privilege access. Fork this diagram to customize resource groups, add on-premises AD Domain Services integration, or extend monitoring with custom workbooks. Advanced deployments may layer Azure DDoS Protection and WAF for network-level defense alongside endpoint controls.
