# Create an ExternalGroup
An ExternalGroup is a grouping of SaaS services (Azure Service/Region, GitHub),
countries, and Threat Feeds that can be used in a Distributed Cloud Firewall
(DCF) rule.
To create an ExternalGroup:
1. In Aviatrix PaaS, go to **Groups > ExternalGroups**. Ensure that you have the
ExternalGroups page selected.
2. Click **+ ExternalGroup**.
3. In the Create ExternalGroup dialog, provide the following information about
your ExternalGroup:
| Parameter | Description |
| - | - |
| Name | Name of the new ExternalGroup. |
| Resource Type | The resource(s) that comprise the ExternalGroup as specified by resource type and matching resource properties. You can add the following Resource Types: - Azure Service or Service Region
- GitHub
- Countries
- Threat Feed (Default ThreatGroup)
If you include more than one Resource Type, OR logic is applied between the Resource Types. AND logic is applied within the Resource Type. |
| Resource Type - Azure | Select one or more Azure cloud-based services or service regions. If you select this Resource Type but leave the value empty, results will be returned for all of your Azure cloud-based services or regions. |
| Resource Type - GitHub | Select one or more GitHub services. If you select this Resource Type but leave the value empty, results will be returned for all of your GitHub services. |
| Resource Type - Country | Select a country. You can only add one country to an ExternalGroup. |
| Resource Type - Threat Feed | Select a Threat Feed (currently only the Default ThreatGroup populated from the Proofpoint Global Threat Database). You can only add one Threat Feed to an ExternalGroup. |
| Preview Resources | After entering your Resource Type, you can use the Preview Resources toggle to see the selected resources that map to the ExternalGroup. |
1. Click **Save**. The new ExternalGroup is now in the ExternalGroups list.
