Azure Firewall
Azure Firewall is a cloud-native, managed network security service that provides stateful firewall capabilities for Azure Virtual Network resources. It offers built-in high availability, unrestricted cloud scalability, and centralized management for filtering network traffic. It integrates with Azure Monitor for logging and analytics, and supports threat intelligence-based filtering to protect against malicious traffic.
Developers should use Azure Firewall when building secure cloud applications on Azure that require centralized network security management, such as in hub-and-spoke architectures or multi-tier applications. It is particularly valuable for scenarios needing application and network-level filtering, outbound SNAT support, or integration with Azure services like Virtual WAN and Azure Bastion for enhanced security posture.
