What is SOC 2 Review?

Definition

SOC 2 Review is a structured assessment of an organization's controls against the Trust Services Criteria established by the AICPA: security, availability, processing integrity, confidentiality, and privacy. The review evaluates whether documented policies, technical safeguards, operational procedures, and evidence demonstrate that controls are appropriately designed and, where applicable, operating consistently.

Organizations commonly use SOC 2 reviews to prepare for a SOC 2 examination, maintain customer assurance, strengthen internal governance, and identify gaps in control documentation. The scope is generally tailored to the services, systems, applications, infrastructure, and data covered by the organization's SOC 2 program.

How a SOC 2 Review Works

A SOC 2 review typically begins by defining the system description, applicable Trust Services Criteria, organizational boundaries, and review period. Reviewers then map controls to relevant risks and determine what evidence demonstrates that each control operates as intended.

  • Define the systems, services, data, and organizational scope.
  • Map business and technology risks to applicable controls.
  • Evaluate policies, procedures, access controls, and monitoring activities.
  • Collect evidence such as logs, approvals, configurations, and review records.
  • Document observations and establish remediation or follow-up actions.

The distinction between control design and operating effectiveness is important. A policy may be appropriately designed on paper while the organization must also demonstrate that the related activity is performed consistently during the relevant period.

Core Control Areas

Security controls commonly address identity and access management, authentication, authorization, vulnerability management, incident response, change management, and infrastructure protection. Availability controls may cover monitoring, capacity planning, backup procedures, disaster recovery, and business continuity.

Processing integrity focuses on whether systems process transactions completely, accurately, and in a timely manner. Confidentiality and privacy controls address how sensitive information is protected, retained, disclosed, and disposed of according to applicable requirements and organizational commitments.

For finance-related systems, the review can intersect with accounting workflows and reporting controls. A well-maintained chart of accounts, for example, supports consistent financial classification and can provide useful evidence when application access and transaction-processing controls are reviewed.

Evidence and Auditability

Evidence is central to a SOC 2 review because reviewers need verifiable support for control activities. Useful evidence can include access reviews, system-generated logs, approval records, configuration snapshots, incident records, training documentation, vendor assessments, and change-management records.

Audit Trails can strengthen the evidence environment by recording relevant actions and changes in vendor management workflows. Clear records help reviewers establish what happened, when it happened, and which person or system performed the activity.

Financial processes can also require connected control evidence. For example, a purchase order workflow may demonstrate approval authority, procurement controls, transaction authorization, and the relationship between an approved purchase and subsequent financial processing.

Finance and Operational Controls

SOC 2 reviews frequently intersect with financial operations when applications process accounting, payment, customer, or vendor information. Reviewers may examine logical access to financial systems, segregation of duties, privileged access, change approvals, data interfaces, and controls surrounding sensitive financial information.

A P L Review can complement this perspective by examining how financial results are reviewed and supported within broader finance and reporting workflows. Similarly, a Coding Review can help assess whether financial transactions are consistently classified and whether relevant coding practices support accurate reporting and control procedures.

Tax-related workflows can also involve sensitive financial data and system controls. Where applications process tax information, controls supporting sales tax validation may be reviewed alongside jurisdiction rules, exemptions, transaction classification, and evidence supporting compliance procedures.

Vendor and Third-Party Considerations

Third-party service providers can affect the scope of a SOC 2 review when they host infrastructure, process information, provide software services, or support critical business functions. Organizations should maintain documented vendor-selection criteria, security requirements, monitoring procedures, and contractual obligations.

Contract Review is relevant when assessing whether agreements establish appropriate security, confidentiality, data-processing, incident-notification, availability, and service obligations. Vendor evidence can then be incorporated into the broader control environment where appropriate.

Best Practices for SOC 2 Readiness

  • Maintain a current inventory of systems, applications, vendors, and sensitive data.
  • Assign clear ownership for each control and define the evidence required to demonstrate operation.
  • Review privileged and user access regularly and retain evidence of approvals and removals.
  • Align change management, incident response, backup, and monitoring procedures with documented policies.
  • Use consistent evidence-retention practices throughout the review period.
  • Track control exceptions and remediation activities to maintain visibility over open items.

Effective readiness is an ongoing governance discipline rather than a one-time documentation exercise. Periodic reviews help organizations keep controls aligned with changes to systems, personnel, vendors, applications, and customer commitments.

Summary

SOC 2 Review provides a structured way to evaluate whether an organization's controls are appropriately designed, documented, supported by evidence, and operating consistently within the defined scope. By connecting technology controls with operational, vendor, accounting, and data-management processes, organizations can strengthen auditability, improve customer assurance, and support disciplined governance. A well-maintained control environment also provides clearer evidence for future examinations and ongoing financial and operational oversight.
