We’ve renamed Microsoft Cloud App Security. It’s now called Microsoft Defender for Cloud Apps. In the coming weeks, we’ll update the screenshots and instructions here and in related pages. For more information about the change, see this announcement. To learn more about the recent renaming of Microsoft security services, see the Microsoft Ignite Security blog.
The following procedure gives you instructions for customizing the Microsoft Defender for Cloud Apps portal.
Prerequisites
For portal access, it’s necessary to add the following IP addresses to your Firewall’s allow list to provide access for the Defender for Cloud Apps portal:
- 104.42.231.28
For US Government GCC High customers, it’s also necessary to add the following IP addresses to your Firewall’s allow list to provide access for the Defender for Cloud Apps GCC High portal:
- 52.227.143.223
- 13.72.19.4
Note
To get updates when URLs and IP addresses are changed, subscribe to the RSS as explained in: Office 365 URLs and IP address ranges.
Set up the portal
- In the Defender for Cloud Apps portal, in the menu bar, select 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. Defender for Cloud Apps 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.
- If you’re integrating with Microsoft Information Protection, see Microsoft Information Protection Integration for information.
- To work with Microsoft Information Protection integration, you must enable the App connector for Office 365.
- If you’re integrating with Microsoft Defender for Identity integration, see Microsoft Defender for Identity Integration for information.
- If at any point you want to back up your portal settings, this screen enables you to do that. Select Export portal settings to create a json file of all your portal settings, including policy rules, user groups, and IP address ranges.
Note
If you use ExpressRoute, Defender for Cloud Apps is deployed in Azure and fully integrated with ExpressRoute. All interactions with the Defender for Cloud Apps apps and traffic sent to Defender for Cloud Apps, including upload of discovery logs, is routed via ExpressRoute for improved latency, performance, and security. There are no configuration steps required from the customer side.
