A SOC 3 Report is a public-facing assurance report that summarizes a service organizationís controls against the Trust Services Criteria without detailed testing results.
Organizations may publish SOC 3 to provide broad transparency about their security and privacy posture for customers and stakeholders. In clinical research vendor selection, SOC 3 can serve as an initial screening artifact before requesting a SOC 2 Type II report. It helps demonstrate baseline commitment to security governance and control design. SOC 3 is less detailed than SOC 2 but can still support procurement and trust-building in regulated environments.
