SOC 2
SOC 2 is an AICPA audit framework evaluating service organizations on five Trust Services Criteria covering security, availability, integrity, and privacy.
Definition
SOC 2 (System and Organization Controls 2) is an auditing framework developed by the American Institute of Certified Public Accountants (AICPA) that evaluates service organizations against five Trust Services Criteria: security, availability, processing integrity, confidentiality, and privacy.
Context
SOC 2 compliance is effectively mandatory for B2B SaaS companies selling to enterprises. A SOC 2 Type II report covers the operating effectiveness of controls over a 6-12 month period, while Type I covers control design at a point in time. SOC 2 reports are the most commonly requested document in security questionnaires, and many questionnaire questions map directly to SOC 2 controls. Automation platforms can leverage SOC 2 control descriptions to draft evidence-backed questionnaire responses.
Why it matters
SOC 2 is an audit framework developed by the AICPA based on five Trust Services Criteria: security, availability, processing integrity, confidentiality, and privacy. Most SaaS vendors pursue SOC 2 Type II reports, which evaluate whether controls operated effectively over a review period of typically six to twelve months. Buyers rely on these reports during vendor assessments to verify that a provider's control environment meets baseline expectations without conducting their own on-site audit.
A frequent mistake is treating SOC 2 preparation as a last-minute documentation exercise. Organizations that begin evidence collection only when the audit window opens often discover control gaps too late to remediate. Effective preparation means running internal readiness assessments at least three months before the observation period starts, ensuring that controls like access reviews, change management approvals, and incident response procedures are already operating consistently and generating the artifacts auditors expect to sample.
The SOC 2 ecosystem has evolved considerably with the rise of continuous compliance platforms that automate evidence collection from cloud infrastructure, version control systems, and HR tools. Auditor firms increasingly accept automated evidence alongside traditional screenshots and policy documents. Practitioners should note that while automation accelerates the process, auditors still evaluate the design of controls and management's risk assessment narrative. The scope decision — which Trust Services Criteria to include — remains a strategic choice that should reflect actual customer contractual requirements.
