+# Automate NSG auditing with Azure Network Watcher security group view
 
-Customers are often faced with the challenge of verifying the security posture of their infrastructure. This challenge is no different for their VMs in Azure. It is important to have a similar security profile based on the Network Security Group (NSG) rules applied. Using the Security Group View, you can now get the list of rules applied to a VM within an NSG. You can define a golden NSG security profile and initiate Security Group View on a weekly cadence and compare the output to the golden profile and create a report. This way you can identify with ease all the VMs that do not conform to the prescribed security profile.
+> [!NOTE]
+> The security group view API is no longer being maintained and will be deprecated soon. Please use the [Effective security rules feature](./network-watcher-security-group-view-overview.md) which provides the same functionality.
