Service Organization Control (SOC) reports allow outsourcing companies to communicate their compliance with security standards and industry best practices to clients. SOC reports provide assurance about the controls in place to protect clients' non-financial data and demonstrate that controls are working effectively. There are two types of SOC II reports - Type I assesses the appropriateness of controls, while Type II verifies the effectiveness of controls over time. SOC II reports benefit users by allowing them to thoroughly evaluate a service provider's security, but may require additional reports from subcontractors or not disclose full details.
