SOC 2 Details
What It Is
SOC 2 (System and Organization Controls 2) is a voluntary attestation framework developed by the AICPA for service organizations handling customer data. It evaluates controls based on Trust Services Criteria (TSC) using a risk-based, principles-focused approach emphasizing design and operating effectiveness.
Key Components
- Five TSC: Security (mandatory, CC1-CC9), Availability, Processing Integrity, Confidentiality, Privacy.
- 50-100 controls mapped to criteria, with redundancy (2-3 per category).
- Built on COSO principles; Type 1 (point-in-time design), Type 2 (operational over 3-12 months).
- Independent CPA audits yield attestation reports.
Why Organizations Use It
- Accelerates enterprise sales, unlocks markets (SaaS/cloud).
- Builds stakeholder trust, reduces VRM friction.
- Mitigates breach risks, enhances resilience.
- Overlaps 80% with ISO 27001, HIPAA, GDPR for efficiency.
- Signals maturity to investors/clients.
Implementation Overview
- Phased: scoping/gap analysis (4-8 weeks), remediation/evidence (8-24 weeks), 3-12 month monitoring, audit.
- Targets SaaS/fintech/HR tech; scalable via tools (Vanta).
- Annual Type 2 recertification with bridge letters.

- Certification via IATF-recognized bodies with staged audits.
Why Organizations Use It
- Meets OEM contractual demands and enables supply chain access.
- Reduces warranty costs, recalls, and COPQ through prevention.
