Note

Microsoft Defender for Cloud Apps is now part of Microsoft 365 Defender, which correlates signals from across the Microsoft Defender suite and provides incident-level detection, investigation, and powerful response capabilities. For more information, see Microsoft Defender for Cloud Apps in Microsoft 365 Defender.

This article provides a list of ports and IP addresses you need to allow and allowlist to work with Microsoft Defender for Cloud Apps.

View your data center

Some of the requirements below depend on which data center you're connected to.

To see which data center you're connecting to, do the following steps:

  1. In the Microsoft 365 Defender portal, select Settings. Then choose Cloud Apps. Under System, select About.

  2. In the About screen, you can see the region and the data center.

    View your data center.

Portal access

To use Defender for Cloud Apps in the Microsoft 365 Defender portal, add outbound port 443 for the following IP addresses and DNS names to your firewall's allowlist:

adaproddiscovery.azureedge.net
*.s-microsoft.com
*.msecnd.net
dev.virtualearth.net
flow.microsoft.com
static2.sharepointonline.com
*.blob.core.windows.net

Additionally, the following items should be allowed, depending on which data center you use:

Data center IP addresses DNS name

Note

For portal access, instead of a wildcard (*), you can choose to open only your specific tenant URL. For example, based on the screenshot above you can open: contoso.us.portal.cloudappsecurity.com. To determine your tenant URL, see the earlier section View your data center, and look for API URL.

Access and session controls

Access and session control regions help provide a faster user experience and increase uptime.

Users are likely to be served from the closest region. For example, a user with a UK IP address is probably to be served by the UK West region.

When there is a high load or outage, the user may be served from a different region.

It is recommended to allow all region addresses in your firewall since there is no guarantee as to which addresses will be used.

Configure your firewall for reverse proxy using the settings relevant to your environment.

Commercial customers

For commercial customers, to enable Defender for Cloud Apps reverse proxy, add outbound port 443 for the following IP addresses and DNS names to your firewall's allowlist:

*.cas.ms
*.mcas.ms
*.admin-mcas.ms

Additionally, the following IP addresses, used by our reverse proxy regions, should be allowed for both inbound and outbound connections:

Note

  • Inbound IP addresses are used to receive incoming connections from end users by the proxy.

  • Outbound IP addresses are used to establish connections from the proxy to the applications.

Note

  • If you didn't specify a proxy when you set up the Defender for Cloud Apps SIEM agent, you need to allow http connections on port 80 for the URLs listed on the Azure TLS certificate changes page. This is used for checking certificate revocation status when you connect to the Defender for Cloud Apps portal.
  • A genuine Microsoft Defender for Cloud Apps certificate usage is required for the SIEM agent connection.

App connector

For some third-party apps to be accessed by Defender for Cloud Apps, these IP addresses may be used. The IP addresses enable Defender for Cloud Apps to collect logs and provide access for the Defender for Cloud Apps console.

Note

You may see these IP addresses in activity logs from the vendor because Defender for Cloud Apps performs governance actions and scans from these IP addresses.

To connect to third-party apps, enable Defender for Cloud Apps to connect from these IP addresses:

Log collector

To enable Cloud Discovery features using a log collector and detect Shadow IT in your organization, open the following items:

  • Allow the log collector to receive inbound FTP and Syslog traffic as configured for the data sources.

  • Allow the log collector to initiate outbound traffic to the Defender for Cloud Apps APIs (for example <mytenant>.us2.cloudappsecurity.com) on port 443 and access to port 53 (DNS services). To find your tenant URL, see View your data center.

  • Allow the log collector to initiate outbound traffic to the Azure blob storage on port 443:

Note

  • If your firewall requires a static IP address access list and does not support allowing based on URL, allow the log collector to initiate outbound traffic to the Microsoft Azure datacenter IP ranges on port 443.
  • If you didn't specify a proxy when you set up the log collector, you need to allow http connections on port 80 for the URLs listed on the Azure TLS certificate changes page. This is used for checking certificate revocation status when you connect to the Defender for Cloud Apps APIs.
