Applies to: Microsoft Cloud App Security

Set up the portal
In the Cloud App Security portal, in the menu bar, click the settings cog and select Settings to configure your organization's details.
Under Organization details, it's important that you provide an Organization display name for your organization. It's displayed on emails and web pages sent from the system.
Provide an Environment name (tenant). This information is especially important if you manage more than one tenant.
It's also possible to provide a Logo that is displayed in email notifications and web pages sent from the system. The logo should be a png file with a maximum size of 150 x 50 pixels on a transparent background.
Make sure you add a list of your Managed domains to identify internal users. Adding managed domains is a crucial step. Cloud App Security uses the managed domains to determine which users are internal, external, and where files should and shouldn't be shared. This information is used for reports and alerts.
- Users in domains that aren't configured as internal are marked as external. External users aren't scanned for activities or files.
Under Auto sign out, specify the amount of time a session can remain inactive before the session is automatically signed out.
