While SOC and ISAE share the same foundation in assurance principles, SOC reports are primarily used for U.S.-based or globally oriented clients and align closely with the Trust Services Criteria for security, availability, processing integrity, confidentiality, and privacy.
SOC 1:
- Focused on internal controls over financial reporting (similar in scope to ISAE 3402);
- Typical audience: External auditors and financial statement users.
SOC 2:
- Focused on non-financial controls related to security, availability, processing integrity, confidentiality, and privacy;
- Typical audience: Clients, regulators, and internal stakeholders.
SOC 3:
- A general-use, public summary of a SOC 2 engagement;
- Typical audience: Marketing and public disclosure.
Together, they form a family of standards that communicate the reliability of your control environment to stakeholders across jurisdictions.
