+### When to use augmented security rules
+
+A single network security group rule can contain multiple values in the Source, Destination, and Service fields. This approach, called augmented security rules, reduces the total number of rules needed and simplifies NSG management. 
+
+**Things to know about augments security rules**
+
+- **Multiple IP addresses**: Combine multiple IP addresses into one rule.
+  
+- **Multiple port ranges**: Specify multiple ports and ranges in the Service field.
+  
+- **Service tags and ASGs**: Mix service tags, application security groups, and IP addresses within the same rule.
+  
+- **Reduced rule count**: Instead of creating separate rules for each IP range or port, combine them into fewer, more manageable rules.
+  
+In enterprise environments with many IP ranges or services, augmented rules prevent NSG rule sprawl. For example, instead of creating four separate rules for ports 80, 443, 8080, and 8090, create one rule with all the ports.
