SOC 2 Details
What It Is
SOC 2 (System and Organization Controls 2) is a voluntary AICPA framework assessing service organizations' commitments to Trust Services Criteria (TSC) for security, availability, processing integrity, confidentiality, and privacy. It uses a control-based, risk-assessed approach with Type 1 (point-in-time design) and Type 2 (operating effectiveness over 3-12 months) reports.
Key Components
- Five TSC: Security (mandatory, CC1-CC9), Availability (A1), Confidentiality (C1), Processing Integrity (PI1), Privacy (P1-P8)
- 50-100 controls per scope, with redundancy (2-3 per category)
- Built on COSO principles and the 2017 TSC (with subsequent AICPA updates)
- CPA-attested reports aiming for unqualified opinions
Why Organizations Use It
- Accelerates sales by satisfying enterprise due diligence (80-90% questionnaires)
- Voluntary yet market-mandated for SaaS/cloud/fintech
- Mitigates breach risks/liabilities (e.g., CCPA exposure)
- Builds competitive moats, investor confidence, partnerships
- Enhances trust with stakeholders via independent assurance
Implementation Overview
Phased: scoping/gap analysis (2-4 weeks), control deployment/automation (4-8 weeks), monitoring (3-12 months), CPA audit (1-2 months). Targets data-handling service orgs (startups to enterprises); tools like Vanta/Drata scale efforts. Annual recertification with bridge letters.
ISO 55001 Details

- Enhances governance, breaks silos, boosts reliability
- Provides competitive differentiation, certification credibility
Implementation Overview
- Phased: gap analysis, SAMP development, training, process controls, audits
- Targets asset-intensive industries (utilities, transport); scalable by size
- Voluntary certification; 12–24 months typical (182 words)
