Google Cloud Identity

Google Cloud Identity centrally manages users and groups as an Identity as a Service solution. It can federate identities between Google and providers such as Active Directory and Microsoft Entra ID, and provides single sign-on to thousands of SaaS applications, including Salesforce, SAP SuccessFactors, and Google Workspace. MFA choices include push notifications, Google Authenticator, Titan Security Keys, security keys, backup codes, SMS, voice calls, passkeys, and other TOTP code generators. Its console manages Android, iOS, and Windows devices, with tools to enforce policies, wipe company data, deploy apps, and view reports. Automated provisioning can create, update, or delete user profile information in third-party cloud applications. Directory Sync extends Active Directory users to the cloud, while Secure LDAP supports traditional applications and infrastructure. Free includes 50 user licenses by default; additional licenses can be requested at no cost. Premium costs $6 a month on an annual fixed-term plan, or $7.20 a month on a flexible plan billed monthly. Premium also lists a 99.9% SLA and 24x7 chat and email support.
