Virtual networks should be protected by Azure Firewall

HIGH

Ensures Azure virtual networks are protected by Azure Firewall for centralized network security and traffic filtering.

What does this mean?

This recommendation ensures that Azure virtual networks route traffic through Azure Firewall, providing centralized network security, threat intelligence-based filtering, and logging of all network flows.

Benefits of implementation

  • Centralized network security and traffic inspection
  • Threat intelligence-based filtering blocks known malicious traffic
  • Full logging and visibility of network flows

Drawbacks and considerations

  • Azure Firewall has significant monthly costs
  • Adds latency to network traffic
  • Requires network architecture changes (hub-spoke or secured virtual hub)

Implementation
