Data
Purview Information Protection, DLP, Insider Risk: classify, label, encrypt and monitor data.
Applications
Defender for Cloud Apps, App Proxy: SaaS discovery, session control, OAuth risk.
Infrastructure
Azure Policy, Defender for Cloud, Azure Arc: posture management across cloud & on-prem.
Network
Azure Firewall, NSGs, Private Link: segmentation, private connectivity, DDoS protection.
