Zero-trust hub-and-spoke network architecture on Azure with integrated identity, security, and global connectivity for distributed enterprises. WPS Users access applications through Azure Front Door with WAF and DDoS protection, while Microsoft Entra ID enforces conditional access and privileged identity management across all zones. Hub VNet hosts Azure Firewall Premium, VPN Gateway, and Azure Bastion; spoke VNets isolate application and data tiers with NSGs and private endpoints connecting to Azure SQL Database, Cosmos DB, and storage services. Azure Virtual WAN and ExpressRoute enable secure hybrid connectivity from global offices in Cayman, Dublin, Hong Kong, Dubai, Bermuda, Singapore, and BVI to the central security hub. Microsoft Sentinel, Defender for Cloud, and Log Analytics provide unified SOC monitoring and threat detection across all workloads including App Service, AKS, Function Apps, and API Management. This architecture demonstrates defense-in-depth with network segmentation, identity governance, and comprehensive security management for regulated enterprises.
