Definition
AICPA · SOC for Service Organizations: Trust Services CriteriaAn attestation report, issued by a licensed CPA firm under AICPA standards, on a service organisation's controls relevant to security and, optionally, availability, processing integrity, confidentiality and privacy. It is not a certificate: the auditor gives an opinion on your system description and controls against the Trust Services Criteria, and you share the report with customers under NDA. Indian SaaS and IT services companies selling to US buyers meet it as a procurement requirement.
