Which of the following would BEST enable an enterprise to ensure selected cloud vendors meet stringent regulatory requirements?

Stage gate reviews are internal project management checkpoints and are not specifically designed to assess a vendor's ongoing regulatory compliance.

While a risk assessment is crucial for understanding potential vendor risks, it is an internal process and may not provide the independent, comprehensive evidence of regulatory compliance that a third-party audit report offers.

An internal audit report of the enterprise itself would assess the enterprise's controls over vendor management, but it would not provide direct evidence of the *vendor's* adherence to regulatory requirements.

Third-party audit reports (such as SOC 2, ISO 27001, or FedRAMP assessments) provide independent verification and assurance that a cloud vendor's security, compliance, and operational controls meet stringent regulatory and industry standards. These reports offer an objective and comprehensive view of the vendor's adherence to required controls, making them the best tool for ensuring compliance.
