SOC 2 is an auditing framework developed by the AICPA that evaluates service organizations' controls for security, availability, processing integrity, confidentiality, and privacy.
SOC 2 (System and Organization Controls 2) is an auditing framework created by the AICPA that evaluates how service organizations manage customer data based on five Trust Services Criteria: Security, Availability, Processing Integrity, Confidentiality, and Privacy. It provides independent assurance of an organization's control environment.
SOC 2 Type I evaluates the design and implementation of controls at a specific point in time. Type II assesses both design and operating effectiveness of controls over a period, typically 6-12 months. Type II provides stronger assurance because it demonstrates consistent control operation, making it preferred by customers and prospects.
The five Trust Services Criteria are Security (protection against unauthorized access), Availability (system operational and usable as agreed), Processing Integrity (system processing is complete and accurate), Confidentiality (information designated as confidential is protected), and Privacy (personal information is collected and used appropriately).
SOC 2 readiness typically requires 3-6 months of preparation to implement controls and gather evidence. A Type I audit takes 4-6 weeks once controls are in place. A Type II audit observation period runs 6-12 months, followed by 4-8 weeks for the auditor to complete testing and issue the report.
SaaS companies, cloud service providers, managed IT service providers, data hosting companies, and any organization that stores, processes, or transmits customer data typically need SOC 2. Enterprise customers and regulated industries increasingly require SOC 2 reports from their vendors as a procurement prerequisite.
While SOC 2 does not explicitly mandate penetration testing, many organizations include it as evidence for the Security Trust Services Criteria. Regular penetration testing demonstrates proactive vulnerability management and strengthens the control environment. Auditors view pentest reports favorably as evidence of security commitment.
Common controls include access management with MFA, encryption at rest and in transit, vulnerability management programs, incident response procedures, change management processes, employee security awareness training, vendor risk management, backup and disaster recovery testing, and continuous monitoring with logging and alerting.
SOC 2 costs vary significantly based on organization size and complexity. Readiness assessments typically run $10,000-$30,000, Type I audits cost $20,000-$60,000, and Type II audits range from $30,000-$100,000 or more. Additional costs include compliance tooling, remediation efforts, and ongoing control maintenance throughout the year.
