The most important requirement to include in an outsourcing contract to help ensure sensitive data stored with a service provider is secure is a third-party assessment report of control environment effectiveness. This will help to verify that the service provider has implemented adequate security controls and practices to protect the data, and that they comply with the enterprise's security policies and standards. A third-party assessment report also provides an independent and objective assurance of the service provider's security posture and performance. Incidents related to data loss, risk assessment results, and cyber insurance policy are also important requirements to include in an outsourcing contract, but they are not as important as a third- party assessment report.
