One of the most useful features was the single sign-on. You can use it as an identity provider or service provider. And you can use their organization unit feature to enable or disable some of the features for a specific group of users.
Google Cloud Identity provides centralized user management for heterogeneous networks, offering features like secure LDAP, vaulted passwords, and application integration. Group access management and single sign-on simplify administrative tasks and enhance security for large organizations. However, integration with Mac's OS and third-party products needs improvement, pricing is higher than AWS, and technical support is slow. LDAP support is also poor.
