Switch to Tenant Restrictions V2 for Enhanced Security

 

Tenant Restrictions in Microsoft Entra

Tenant restrictions play a crucial role in safeguarding corporate networks from unauthorized access and potential data exfiltration by managing user and application access across external tenants. The evolution from Tenant Restrictions v1 to v2 introduces significant improvements, offering admins enhanced control, flexibility, and ease of policy management directly from the Microsoft Entra portal. By eliminating the constraints of proxy header updates and partner number limitations, Tenant Restrictions v2 allows for a more finetuned security posture.

Tenant restrictions are essential to prevent data theft via unauthorized access to external Microsoft Entra ID tenants and consumer Microsoft accounts. Tenant restrictions v1 allowed for an allow list of tenant IDs and Microsoft sign-in endpoints, ensuring access to external tenants authorized by your organization. Compared to tenant restrictions v1, tenant restrictions v2 offers finer control and easier policy management without extra licensing demands.

• Update the policy from the Microsoft Entra portal without needing to adjust each network proxy.
• Remove size limitations on your maximum proxy header length, allowing unlimited partners with tenant restrictions v2.
• Selectively manage which user groups can access specific apps in external tenants, offering more precise control than allowing entire tenant access for all identities.
