SOC 2 is a cloud service security certification framework established by the American Institute of Certified Public Accountants (AICPA) that evaluates the level of control over overall service operations based on five trusted service criteria: security, availability, process integrity, confidentiality, and privacy. Among these, Type II is a certification that verifies through external audits that security controls have been effectively operated over a certain period, and it has established itself as the most stringent security standard required by global enterprise companies when selecting partners.
