Your company runs its identities in on-premises Active Directory but now uses more than a dozen SaaS applications spread across multiple public clouds. Users complain about juggling separate credentials for each service, and the CISO wants to streamline access while keeping authentication centralized under corporate control. Which strategy BEST meets this goal and provides seamless access across all cloud applications?
Implement a SAML-based single sign-on solution that federates Active Directory identities with each cloud service
Deploy individual VPN gateways for each SaaS application and require users to connect before logging in
Create local accounts in every SaaS application and synchronize user passwords on a weekly schedule
Require every SaaS vendor to issue its own mutual-TLS client certificates to users for application access
Using a SAML-based single sign-on platform federates on-premises identities with each SaaS provider. Users authenticate once to the identity provider, which issues SAML assertions trusted by the cloud services, eliminating multiple passwords and accounts while preserving centralized policy enforcement. Maintaining local accounts or password-sync jobs still creates multiple credentials to manage, separate VPN gateways do not solve authentication sprawl, and per-vendor client certificates fragment identity management rather than unify it.
