Azure Firewall Architecture Diagram

This diagram illustrates a typical deployment of Azure Firewall, showcasing its integration within a Virtual Network (VNet) and its role in protecting your Azure and on-premises resources.

Key components often include:

• Hub VNet: Centralized network for management and security appliances like Azure Firewall.
• Spoke VNets: Workload VNets that peer with the hub VNet and route traffic through the firewall.
• On-premises Network: Connected via VPN Gateway or ExpressRoute, traffic can be inspected by the firewall.
• Azure Firewall: The managed, cloud-native network security service that protects your Azure VNet resources.
• Network Security Groups (NSGs): Applied at the subnet level for additional filtering.
• Route Tables: Used to force network traffic through the Azure Firewall.
• Azure Monitor: For logging and monitoring firewall activity.

This architecture provides a centralized point of control for security policies, threat intelligence, and network traffic inspection.
