About This Architecture

Hybrid cloud security architecture integrating Azure-native services with third-party and on-premises security tools across identity, compute, and governance layers. Data flows from external/edge protection through identity and access controls into hybrid compute workloads, with centralized security operations monitoring via Microsoft Sentinel SIEM/SOAR. This blueprint demonstrates zero-trust principles using Azure Entra ID, Conditional Access, Azure Bastion, and Microsoft Defender for Cloud alongside like-for-like alternatives like SentinelOne EDR and Delinea PAM. Security architects can fork this diagram to customize provider selections, adjust hybrid/cloud ratios, or document their own multi-cloud defense posture. The architecture balances Azure-native cost efficiency with flexibility to retain existing security investments during cloud migration.

How do I design a hybrid cloud security architecture that integrates Azure-native services with on-premises and third-party security tools?

This diagram shows a four-layer hybrid security model: External/Edge (WAF, DDoS, Front Door), Identity and Access (Entra ID, Conditional Access, MFA, PAM), Compute and Workloads (on-premises VMs, Azure VMs, EDR), and Security Operations (Sentinel SIEM, Defender for Cloud, monitoring). It balances Azure-native replacements with like-for-like alternatives, enabling gradual migration while maintainin
