Conditional Access: Block access by location

  • How-to

With the location condition in Conditional Access, you can control access to your cloud apps based on the network location of a user. The location condition is commonly used to block access from countries/regions where your organization knows traffic shouldn't come from. For more information about IPv6 support, see the article IPv6 support in Microsoft Entra ID.

Note

Conditional Access policies are enforced after first-factor authentication is completed. Conditional Access isn't intended to be an organization's first line of defense for scenarios like denial-of-service (DoS) attacks, but it can use signals from these events to determine access.
