SOC 3 — System and Organization Controls Public Assurance Report
SmartSuite provides the system for managing controls, evidence, mappings, assessments, and reporting. Framework text may require a separate license unless explicitly provided.
Overview
SOC 3 --- System and Organization Controls Public Assurance Report is an external attestation report that allows organizations to communicate the effectiveness of their internal controls related to security, availability, processing integrity, confidentiality, or privacy to a broad audience. This report provides stakeholders with confidence that an independent CPA has evaluated how the organization manages risks related to information security and data protection.
Developed and published by the American Institute of Certified Public Accountants (AICPA), SOC 3 reports are most often utilized by service organizations seeking to assure customers, business partners, and the general public about their cybersecurity and compliance posture. SOC 3 shares the same Trust Services Criteria as SOC 2, but is intended for public distribution and does not include detailed descriptions of controls or results.
To achieve SOC 3 reporting, organizations coordinate with independent service auditors to assess the design and operational effectiveness of applicable internal controls.
Why it Matters
SOC 3 reports provide a transparent and independent assessment of an organization's internal controls related to security, confidentiality, and privacy.
Key benefits include:
Build stakeholder trust
Demonstrate to customers and the public that internal controls have been independently evaluated and meet recognized security standards.
Increase audit readiness
Provide a streamlined, externally validated report that supports ongoing audit requirements and reduces time spent on repetitive due diligence.
Enhance regulatory alignment
Support compliance efforts by aligning internal processes with widely accepted criteria from the AICPA Trust Services Criteria framework.
Strengthen data protection practices
Offer assurance that mechanisms to safeguard sensitive and confidential information are both present and regularly assessed for effectiveness.
Promote operational resilience
Validate that systems supporting essential business operations remain robust, available, and resilient against potential cyber threats or disruptions.
How it Works
SOC 3 is structured around the AICPA Trust Services Criteria---security, availability, processing integrity, confidentiality, and privacy---and establishes control objectives and criteria that organizations map to their systems.
Organizations implement SOC 3 by applying security controls and governance practices that align with the Trust Services Criteria, performing risk assessments, and maintaining monitoring and evidence of control operation.

Frequently Asked Questions For SOC 3 (System and Organization Controls Public Assurance Report)
SOC 3 is used to publicly demonstrate that an organization’s internal controls related to security, availability, processing integrity, confidentiality, and privacy have been independently assessed and found effective. It provides assurance to customers, partners, and the general public about the organization’s cybersecurity and compliance posture.
SOC 3 is not mandatory by law or regulation; it is a voluntary attestation report. Unlike a formal certification, SOC 3 is a third-party assurance provided by an independent CPA firm, confirming that controls were evaluated against the AICPA Trust Services Criteria.
SOC 3 reports apply primarily to service organizations that want to communicate their control environment to a broad, non-technical audience. The scope covers internal controls relevant to the Trust Services Criteria but does not provide detailed descriptions of controls or test results, ensuring suitability for public distribution.
Key artifacts for SOC 3 include the description of the system in scope, the articulation of applicable Trust Services Criteria, and evidence showing control design and operational effectiveness. The final report summarizes the auditor’s opinion without disclosing sensitive details.
Organizations implement SOC 3 by mapping their internal controls to the Trust Services Criteria, performing risk assessments, and establishing governance and monitoring processes. Preparation involves internal control evaluation, remediation of gaps, and engagement with a service auditor to perform the attestation.
SOC 3 is based on the same Trust Services Criteria as SOC 2 but is intended for general public consumption and contains no detailed control testing results. Unlike SOC 2, which is shared only under NDA with customers, SOC 3 can be freely distributed and often complements broader compliance efforts such as ISO 27001.
Organizations maintaining SOC 3 assurance must have continuous internal control monitoring, periodic risk assessment, robust governance, and timely remediation processes. Annual or regular engagement with a qualified service auditor is usually required to issue updated public reports.
SmartSuite supports SOC 3 by enabling organizations to import control libraries mapped to the Trust Services Criteria, manage risks with a centralized register, collect and store audit evidence, track remediation activities, and generate dashboards and reports for audit readiness. These features streamline control management and facilitate external assurance processes.
