🛡️ Microsoft Defender for Cloud

What it is: A cloud-native CSPM (Cloud Security Posture Management) and workload protection platform.
Why it’s critical: Defender for Cloud continuously assesses resource configurations, provides secure score recommendations, and integrates threat intelligence across IaaS, PaaS, and hybrid workloads.
Capabilities include:

• Security posture management (Secure Score)
• Threat protection for VMs, containers, databases, and APIs
• Regulatory compliance mappings (NIST, CIS, ISO)
• Integration with Microsoft Defender XDR

📜 Azure Policy

What it is: A governance and compliance engine for enforcing organisational security standards.
Why it matters: Prevents drift and misconfiguration by applying rules across resource groups, subscriptions, or tenants.
Use cases:

• Blocking public IPs or unencrypted storage
• Enforcing tagging and region restrictions
• Auditing VMs for endpoint protection

---

🔐 Microsoft Defender XDR

What it is: An extended detection and response solution that unifies signals from endpoints, identities, email, and cloud apps.
Why it’s powerful: Correlates threats across domains, enabling quicker detection and response.
Components include:

• Defender for Endpoint
• Defender for Identity
• Defender for Office 365
• Defender for Cloud Apps

🧬 Microsoft Entra ID Protection (formerly AAD Identity Protection)

What it is: A cloud-based identity risk management system.
Why it’s essential: Uses behavioural analytics and machine learning to detect and respond to suspicious sign-ins and user risk.
Core Benefits:

• Automates account protection with conditional access
• Detects risky users and sign-ins
• Integrates with SIEM and SOAR for incident triage

---

🗂️ Microsoft Purview (Data Protection & Insider Risk)

What it is: A unified data governance and compliance suite.
Why it’s used: Helps classify and protect sensitive data, manage regulatory risk, and monitor insider activity.
Security Capabilities:

• Sensitivity labels and auto-classification
• Insider risk scoring and investigation workflows
• Integration with Microsoft 365 apps and DLP

👥 Microsoft 365 Security & Compliance

What it includes: Security and data protection features embedded in Exchange, SharePoint, Teams, and OneDrive.
Why it matters: Provides granular control over collaboration security, eDiscovery, and compliance.
Tools of note:

• Microsoft 365 Defender integration
• Communication compliance
• Information barriers and audit logging

🔎 Azure Security Center (now part of Defender for Cloud)

What it was: The former centralised dashboard for Azure security.
Current role: Fully integrated into Defender for Cloud, providing visibility into misconfigurations, threats, and compliance status.
