+  **Timestamp** - Data-collection timestamp 
+  **Number of CloudFormation Stacks deployed in the account** 
+  **Number of Firewalls managed** 
+  **Number of Firewall Policies managed** 
+  **Number of stateful rule groups deployed** 
+  **Number of stateless rule groups deployed** 
+  **Number of Suricata rules deployed** 
+  **Network Firewall Destination Type** 
+  **Network Firewall Log Type**
