SOC 2 (Service Organization Control 2) is an auditing framework developed by the AICPA (American Institute of CPAs) that evaluates whether a service organisation's controls are suitably designed and, for Type II, operating effectively to meet the Trust Services Criteria (TSC) — Security, and optionally Availability, Processing Integrity, Confidentiality, and Privacy.
SOC 2 is for service organisations that store, process, or transmit customer data — including SaaS providers, cloud hosting providers, data centres, managed service providers (MSPs), BPOs, payroll processors, payment processors, and any vendor that handles sensitive data on behalf of clients. US enterprises and regulated industries (healthcare, financial services) often require SOC 2 reports from their vendors. Indian IT/ITES and BPO companies serving US clients are increasingly asked to obtain SOC 2 Type II to win and retain contracts.
