Once you have added and verified your asset it's time to start creating your scan profiles. A scan profile can be either a top level domain, subdomain, an IP address or a specific configuration of any of these, such as a top level domain in an authenticated state. 

You can create a scan profile by going to your Asset Inventory and clicking "Create scan profile" which appears next to the root asset on the right hand side:

You can also click on "Create Profile" in the top right hand corner of your Root Asset Overview

If you wish to rename your scan profile, you can do so by clicking into the specific scan profile on your dashboard, navigating to Profile Settings which appear under "Settings" in the left hand navigation menu. Under "Want to rename the profile to find it easier?" which appears at the top, click "edit" to change the name of your scan profile:
