Network security policies are constantly evolving to keep pace with the demands of workloads. With the acceleration of workloads to the cloud, network security policies—Azure Firewall policies in particular—are frequently changing and often updated multiple times in a week (in many cases several times in a day). Over time, the Azure Firewall network and application rules grow and can become suboptimal, impacting the firewall performance and security. For example, high volume and frequently hit rules can be unintentionally prioritized lower. In some cases, applications are hosted in a network that has been migrated to a different network.
