Microsoft Defender is a security portfolio, not a single switch. Use this hub to choose the right protection for cloud workloads, devices, identities, data, and security operations.
Understand the boundaries between Defender for Cloud, Defender XDR, Sentinel, and enforcement tools.
Cloud postureDiscover cloud risk, assess configuration, and prioritize remediation across Azure, AWS, and GCP.
Workload protectionSecure AKS, Arc-enabled Kubernetes, registries, and supported multicloud container estates.
Workload protectionPlan detection and response for Windows and Linux across Azure, hybrid, and multicloud environments.
Security operationsCorrelate endpoint, identity, email, cloud app, and cloud workload signals into unified incidents.
DeploymentUse a structured path for licensing, pilot scope, verification, response ownership, and rollout.
PlanningCompare Defender plans and tiers, check regional support, configure settings, and estimate cost.
| Environment | Recommended starting point |
|---|---|
| Azure | Use the Defender for Cloud navigation section for workload-specific plans. |
| AWS and Google Cloud | Multicloud and hybrid guidance |
| On-premises and other clouds | Azure Arc onboarding |
| Microsoft 365 and SaaS | Use the Microsoft Ecosystem navigation section. |
Before a pilot, use the configuration, plans, and pricing reference to configure Defender settings, compare tiers, verify regional eligibility, and open current pricing and cost-calculation tools.
Start with the overview to establish product boundaries, then select the guide that owns the asset or identity you need to protect. Each guide follows the same operating sequence: define scope and ownership, confirm support and licensing, enable a controlled pilot, verify telemetry and response, then expand with evidence-backed controls. Use the deployment checklist to record the decision, the operations guides to establish governance and automation, and the product guides to define service-specific prevention and response actions.
