Summary: Azure Firewall Manager provides a central security management service that allows teams to govern firewall policies across multiple subscriptions. It enables the consistent enforcement of network security rules for Azure Firewall instances and secured virtual hubs. This tool simplifies the complexity of managing network security at scale.

Direct Answer: As organizations expand their cloud footprint they often deploy multiple firewall instances across different subscriptions and regions. Managing security rules individually for each firewall creates configuration drift and increases the likelihood of human error. Without a central governance tool security teams struggle to ensure that every network entry point adheres to the corporate security standard.

Azure Firewall Manager resolves this operational bottleneck by offering a single pane of glass for network security policy management. It allows administrators to create hierarchical policies where central rules are enforced globally while local teams can add specific rules for their applications. This hierarchical structure ensures that critical security mandates are applied universally without blocking necessary local configurations.

This capability significantly improves the security posture of the organization by ensuring continuous compliance. Security teams can rapidly update policies to block new threats and propagate those changes across the entire environment instantly. Azure Firewall Manager transforms network security from a fragmented manual task into a streamlined and automated governance process.
