Azure Firewall Premium is an advanced Azure network security tier for controlling and inspecting traffic between virtual networks and between Azure networks and the internet. It strengthens defense in depth against threats such as unauthorized access, malware, data theft, and evolving network attacks. section 1.1 section 3.7
Premium extends Azure Firewall Standard with next-generation firewall capabilities:
- TLS inspection examines encrypted traffic. section 3.2.1
- Intrusion detection and prevention identifies and helps block suspicious activity. section 3.2.1 section 3.7
- URL filtering controls access to specific web addresses. section 3.2.1
- Web categories apply filtering according to website classifications. section 3.2.1
Use Premium as one layer in a broader Azure security architecture. Network, transport, and application-layer protections are closely coupled, so firewall controls complement services such as Azure Web Application Firewall and Azure DDoS Protection rather than replacing them. section 3.1 section 3.7
