Enable cross-tenant isolation

Cross-tenant isolation lets you restrict other tenants your makers can connect to. Applied at the connector level, cross-tenant isolation blocks inbound or outbound connections for canvas apps and flows.

Enabling cross-tenant isolation for Power Apps and Power Automate requires raising a support ticket in the Power Platform admin center.

  • Restricting outbound connections means a user in your tenant is blocked from connecting to a third-party tenant. Restricting outbound cross-tenant connections can be done using tenant restrictions that apply to all Azure Active Directory (Azure AD) software as a service (SaaS) cloud apps, or at the connector level, which would block outbound connections just for canvas apps and flows.

  • Restricting inbound connections means a user in a third-party tenant is blocked from creating a connection to your tenant. Restricting inbound cross-tenant connections requires a support ticket—this restriction then only applies to Power Apps and Power Automate.

Azure AD tenant restrictions

Tenant restrictions can also control access to all SaaS cloud applications, based on the Azure AD tenant the applications use for single sign-on. More information: Use tenant restrictions to manage access to SaaS cloud applications
