Azure Virtual Network Manager rule impact analyzer is now generally available, empowering you to simulate the impact of your security admin rules on your virtual networks before deploying your rules.
With this capability, you can simulate the effects of your security admin rules on your virtual networks’ existing traffic flows and modify rules as needed to ensure your desired traffic flows are maintained and reduce the risk of unexpected connectivity issues.
This feature is available in the Azure portal and is powered by Azure Network Watcher traffic analytics and virtual network flow logs, providing data-driven insights into how security admin rule deployments could affect your existing virtual network traffic.
