    SOC 2 Details

    What It Is

    SOC 2 (System and Organization Controls 2) is a voluntary attestation framework developed by the AICPA to evaluate service organizations' controls over customer data. It uses Trust Services Criteria (TSC)—a risk-based, principles-focused approach emphasizing Security (mandatory) plus optional Availability, Processing Integrity, Confidentiality, and Privacy.

    Key Components

    • Five TSC pillars, with Common Criteria (CC1-CC9) under Security covering control environment, risk assessment, access, monitoring, and vendors.
    • ~50-100 controls mapped to TSC, requiring redundancy (2-3 per point).
    • Built on COSO principles; Type 1 (design) and Type 2 (operating effectiveness over 3-12 months) reports issued by CPA auditors.

    Why Organizations Use It

    • Accelerates enterprise sales, shortens due diligence by 80-90%.
    • Mitigates breach risks, builds stakeholder trust for SaaS/cloud providers.
    • Voluntary but market-driven; overlaps with ISO 27001, HIPAA, GDPR for efficiency.
    • Competitive moat unlocking higher ACV deals, investor confidence.

    Implementation Overview

    • Phased: scoping/gap analysis (4-8 weeks), deployment/monitoring (3-6 months), CPA audit.
    • Targets SaaS/fintech/HR tech; scalable via automation (Vanta, Drata).
    • Annual Type 2 recertification with bridge letters for continuity. (178 words)

    ISO 27701 Details

    What It Is

    ISO/IEC 27701:2025 is the international standard defining requirements for a Privacy Information Management System (PIMS). It guides organizations in managing privacy risks for processing personally identifiable information (PII) as controllers or processors. Employing a risk-based PDCA cycle, it aligns with ISO/IEC 27001 while enabling standalone implementation.

    Key Components

    • Clauses 4–10: Context, leadership, planning, support, operation, evaluation, improvement.
    • **Annex AControls for PII controllers (e.g., consent, DSARs, retention).
    • **Annex BControls for PII processors (e.g., contracts, sub-processors).
    • Mappings to GDPR (Annex D), ISO 27001/27002. Certification via accredited bodies' two-stage audits.

    Why Organizations Use It

    • Demonstrates accountability for GDPR/POPIA/LGPD compliance.
    • Integrates privacy into security governance.
    • Reduces breach risks, fines; boosts procurement trust.
    • Enhances reputation, competitive differentiation.

    Implementation Overview

    Phased: scope/gap analysis, risk assessment, controls rollout, internal audits. Applies to all PII-processing organizations globally. Optional certification with 3-year validity, annual surveillance.
