SOC 2 compliance is a framework developed by the American Institute of Certified Public Accountants (AICPA) that evaluates how an organization manages customer data based on five trust service criteria: security, availability, processing integrity, confidentiality, and privacy. Unlike prescriptive regulatory standards, SOC 2 is principles-based, meaning each organization defines its own controls and processes to satisfy the criteria relevant to its operations.
A SOC 2 certification (formally, a SOC 2 report issued by an independent auditor) demonstrates to customers, partners, and regulators that your organization has designed and operates effective controls over its systems and data. For fintechs, banks, and financial institutions, SOC 2 compliance is often a prerequisite for enterprise sales, sponsor bank onboarding, and partnership agreements.
SOC 2 compliance also intersects with broader information security frameworks. Organizations that align their SOC 2 controls to the NIST Cybersecurity Framework (CSF) benefit from a control architecture that maps across multiple regulatory and certification requirements, reducing duplication and strengthening overall security posture.
SOC 2 type 1 vs type 2
Understanding the difference between SOC 2 Type 1 and SOC 2 Type 2 is critical for scoping your engagement and setting expectations with customers and partners.
SOC 2 Type 1 evaluates the design of your controls at a single point in time. The auditor assesses whether your controls are suitably designed to meet the relevant trust service criteria as of a specific date. A Type 1 report is often used as a first step for organizations that are new to SOC 2 compliance and need to demonstrate baseline control maturity.
SOC 2 Type 2 evaluates both the design and the operating effectiveness of your controls over a defined observation period, typically 6 to 12 months. The auditor tests whether controls functioned consistently throughout the period, not just whether they were designed correctly. A SOC 2 Type 2 report carries significantly more weight with enterprise buyers, bank partners, and regulators because it provides evidence of sustained operational discipline.
Most organizations begin with a Type 1 engagement to establish the foundation, then transition to Type 2 for ongoing SOC 2 type 2 compliance. Equinox Compliance supports both engagement types and helps you determine the right sequencing based on your business timeline, customer requirements, and risk profile.
SOC 2 compliance requirements
SOC 2 compliance requirements are organized around the five trust service criteria defined by the AICPA. Security is required for every SOC 2 engagement. The remaining four criteria (availability, processing integrity, confidentiality, and privacy) are selected based on the nature of your services and what matters most to your customers and partners.
Security (required)
The security criterion, also known as the common criteria, covers protection of systems and data against unauthorized access. This includes logical and physical access controls, network security, encryption, vulnerability management, and incident response. Security forms the foundation of every SOC 2 report.
Availability
The availability criterion addresses whether systems are operational and accessible as committed in service-level agreements. This includes uptime monitoring, disaster recovery, business continuity planning, and capacity management.
Processing integrity
Processing integrity evaluates whether system processing is complete, valid, accurate, timely, and authorized. This criterion is especially relevant for fintechs handling transactions, payments, and financial data where processing errors create direct financial and regulatory risk.
Confidentiality
The confidentiality criterion covers the protection of information designated as confidential. This includes data classification, access restrictions, encryption of data at rest and in transit, and secure data disposal.
Privacy
The privacy criterion addresses how personal information is collected, used, retained, disclosed, and disposed of. This criterion aligns closely with privacy regulations and is relevant for organizations handling consumer data at scale.
Organizations that map their SOC 2 controls to NIST CSF gain a structured approach to satisfying these requirements while building a control environment that extends to other compliance frameworks such as ISO 27001 and PCI-DSS.
What comes next
Once you understand the framework and requirements, the next step is building your control environment and preparing for the audit. Our SOC 2 compliance checklist walks through the full sequence: scoping, readiness assessment, controls design, evidence collection, and what to expect during the audit itself.
