Add a Subdomain

In Tenable Attack Surface Management, you can add a subdomain to an existing domain in your inventory.

To add a subdomain to a domain in your inventory:

1. On the Explore page, in the All Sources pane, next to the source, click the button.

   A menu appears.

   

2. In the drop-down list, click Add subdomain.

   The Add missing subdomain window appears.

3. In the text box, type a subdomain or comma-separated list of subdomains.

4. Click Add subdomains.

   The subdomains are added to your inventory and Tenable Attack Surface Management automatically begins identifying assets in the subdomain.
