Microsoft Defender for Endpoint (MDE) is an enterprise endpoint security platform designed to help networks prevent, detect, investigate, and respond to advanced threats. It provides next-generation protection, endpoint detection and response (EDR), automated investigation, and threat & vulnerability management across Windows, macOS, Linux, Android, and iOS.
Discover, assess, and remediate endpoint vulnerabilities and misconfigurations in real time. Prioritize based on threat context and business criticality.
Reduce the attack surface with ASR rules, hardware-based isolation, application control, exploit protection, and network protection.
Cloud-delivered protection with Microsoft Defender Antivirus. behavioral monitoring, heuristics, and real-time threat intelligence powered by AI/ML.
Advanced hunting, incident visualization, alert correlation, and deep forensic analysis. Investigate and respond to threats across your endpoint fleet.
AIR examines alerts and takes immediate remediation actions to resolve breaches, reducing alert volume and allowing SOC teams to focus on advanced threats.
Discover unmanaged devices on your network and seamlessly onboard them. Support for GPO, Intune, SCCM, local scripts, and VDI environments.
Use Kusto Query Language (KQL) to proactively search for threats across endpoint telemetry, process events, network connections, and file activities.

Plan deployment rings, create onboarding packages via Group Policy and Intune, deploy to Windows Server 2022 machines, verify device health in the security portal, and troubleshoot common onboarding failures across an enterprise domain.
Audit your current attack surface, deploy ASR rules in audit mode via Intune, analyze the impact report for business-critical applications, transition to block mode, and configure targeted exclusions for line-of-business apps.
Trigger a safe ransomware simulation on a test endpoint, trace the full attack chain in the device timeline, analyze process trees and file modifications, collect an investigation package, perform live response remediation, and document the incident.
Configure next-generation protection policies with Intune, enable EDR in block mode, create custom indicators (file hash, IP, URL, certificate), set up device groups with RBAC, build automated investigation playbooks, and create a custom security reporting dashboard.
