-Universal tenant restrictions v2 as part of [Microsoft Entra Global Secure Access](https://learn.microsoft.com/azure/global-secure-access/overview-what-is-global-secure-access) is recommended because it provides authentication and data plane protection for all devices and platforms. This option provides more protection against sophisticated attempts to bypasses authentication. For example, attackers might try to allow anonymous access to a malicious tenant’s apps, such as anonymous meeting join in Teams. Or, attackers might attempt to import to your organizational device an access token lifted from a device in the malicious tenant. Universal tenant restrictions v2 prevents these attacks by sending tenant restrictions v2 signals on the authentication plane (Microsoft Entra and Microsoft Account) and data plane (Microsoft cloud applications).
