SOC 1

SOC 1 is a report framework for service organizations addressing controls relevant to user entities' financial reporting. It is issued under standards maintained by the American Institute of Certified Public Accountants and mapped to international assurance standards, providing attestation on control design and operating effectiveness for auditors and stakeholders in regulated industries.

Overview

SOC 1 reports arise from standards promulgated by the American Institute of Certified Public Accountants under SSAE 18, and are often associated with international guidance such as ISAE 3402 issued by the International Auditing and Assurance Standards Board. They are delivered by licensed practitioners from firms like Deloitte, PricewaterhouseCoopers, Ernst & Young, KPMG, BDO International, Grant Thornton, RSM International, Crowe Global, Mazars, and PKF International. Organizations in sectors including JPMorgan Chase, Bank of America, Citigroup, Wells Fargo', Goldman Sachs, Morgan Stanley, HSBC Holdings, Barclays, Deutsche Bank, UBS Group, Credit Suisse, BNP Paribas, Santander, ING Group, UBS, and Societe Generale commonly seek these reports to support audits led by firms such as Big Four accounting firms and regional auditors like BDO USA.

Purpose and Scope

The primary purpose is to provide assurance to user entity auditors—often associated with Ernst & Young Global Limited engagements, Deloitte Touche Tohmatsu Limited reviews, or PwC attestations—on controls at a service organization that are likely to be relevant to the financial reporting of user entities such as Microsoft Corporation, Oracle Corporation, SAP SE, ADP, Fiserv, Intuit Inc., Salesforce, Amazon Web Services, Google Cloud Platform, IBM, Accenture, Capgemini, Infosys, Tata Consultancy Services, and Cognizant. The scope is typically restricted to controls over processing transactions, authorization, recording, and reconciliation activities that affect entities like Visa Inc., Mastercard Incorporated, PayPal Holdings, Square, Inc., Stripe, Inc., Fidelity Investments, Vanguard Group, BlackRock, Inc., State Street Corporation, and Charles Schwab Corporation.

Types and Reports (Type I and Type II)

There are two primary report types used by practitioners such as Arthur Andersen alumni or partners at KPMG International: a Type I report describes control design as of a specific date for entities including American Express, Capital One Financial Corporation, Discover Financial Services, and Ally Financial, while a Type II report adds an audit of operating effectiveness over a period, used by firms like SunTrust Banks and BB&T Corporation (now Truist Financial). Type II reports are often requested by auditors from Grant Thornton LLP, BDO USA LLP, Mazars USA LLP, and Crowe LLP when auditing client accounts at Goldman Sachs Group, Inc., J.P. Morgan Chase & Co., Morgan Stanley, or Citigroup Inc..

Control Objectives and Common Controls

Control objectives in these reports frequently target areas relevant to institutions such as HSBC, Lloyds Banking Group, Royal Bank of Scotland Group, Banco Santander, and Mitsubishi UFJ Financial Group. Common controls include logical access controls similar to practices at Cisco Systems, Juniper Networks, Fortinet, physical security controls used by Equinix, Digital Realty, Iron Mountain, change management processes like those at Atlassian Corporation, GitHub, GitLab B.V., backup and recovery strategies mirroring ServiceNow or Zendesk, and incident response frameworks akin to FireEye, CrowdStrike Holdings, or Palo Alto Networks. Control objectives also address segregation of duties practiced at American Airlines Group, Delta Air Lines, United Airlines Holdings, Maersk, FedEx Corporation, and UPS.

Examination Process and Standards

Exams are performed by certified public accountants affiliated with AICPA member firms, following attest engagement guidelines from SSAE 18 and referencing ISAE 3402 for cross-border consistency. The process includes scoping, risk assessment, walkthroughs, control testing, sampling, evidence collection, and reporting—activities familiar to audit teams at PwC, Deloitte, EY, KPMG, Grant Thornton, BDO, Mazars, Crowe, RSM, and PKF. Examinations often interact with regulatory exams by authorities such as the Securities and Exchange Commission, Federal Reserve Board, Office of the Comptroller of the Currency, Prudential Regulation Authority, European Banking Authority, Financial Conduct Authority, and Monetary Authority of Singapore.

Use Cases and Stakeholders

Stakeholders include user entity auditors at firms like KPMG LLP, Ernst & Young LLP, Deloitte LLP, PricewaterhouseCoopers LLP, internal audit functions at Apple Inc., Alphabet Inc., Meta Platforms, Inc., Tesla, Inc., Netflix, Inc., procurement teams at Procter & Gamble, Unilever, Nestlé, Johnson & Johnson, Pfizer, GlaxoSmithKline, Novartis, Roche, and compliance officers at Pfizer, AstraZeneca, Bayer, and Merck & Co.. User entities in finance, payroll, data center, and cloud services—such as ADP, Paychex, Equinix, AWS, Microsoft Azure, Google Cloud—use reports to support financial statement audits, vendor risk management, and regulatory filings with entities like SEC and PCAOB.

Criticisms and Limitations

Critiques come from practitioners, regulators, and client firms including Public Company Accounting Oversight Board, European Securities and Markets Authority, Financial Stability Board, and academics at Harvard University, Stanford University, University of Oxford, London School of Economics, Massachusetts Institute of Technology, and University of Chicago, who note limitations: reports focus narrowly on financial-reporting-relevant controls rather than comprehensive cybersecurity posture as emphasized by NIST, ISO/IEC 27001, CIS Controls, GDPR, HIPAA, and SOC 2 frameworks; timing and scope constraints for entities like Uber Technologies, Lyft, Inc., Airbnb, Inc.; variance in practitioner procedures across firms such as PwC, Deloitte, EY, and KPMG; and potential mismatch for stakeholders like Vanguard, BlackRock, State Street needing continuous assurance. Users sometimes request complementary attestations—parallel to SOC 2 or ISO 27001 certifications—issued by bodies such as British Standards Institution, American National Standards Institute, International Organization for Standardization, or national auditors.
