Reviewing the third-party's financial stability, security practices, and industry reputation provides an overview of the potential risks and benefits of doing business with them. It is important for the company to make a well-informed decision to mitigate any risks that could be associated with the third-party service provider. While meeting with the third-party's security personnel is important, it does not offer the comprehensive view that financial and industry considerations provide. Similarly, deploying a test environment could be a part of the assessment, but it is not comprehensive due diligence on its own. Lastly, conducting a background check on key personnel primarily covers the trustworthiness of the individuals rather than the provider's overall fit and capability.
