SOC 2
A security audit standard developed by the AICPA assessing a service company's data security, availability, processing integrity, confidentiality, and privacy controls.
SOC 2 (Service Organization Control 2) is a voluntary compliance framework and audit standard developed by the American Institute of CPAs (AICPA) that evaluates and reports on controls at a service organization relevant to security, availability, processing integrity, confidentiality, and privacy — collectively called the Trust Services Criteria (TSC). It has become the de facto security compliance standard for SaaS companies and cloud service providers serving enterprise customers.
The five Trust Services Criteria: Security (the system is protected against unauthorized access), Availability (the system is available for operation as committed), Processing Integrity (processing is complete, valid, accurate, timely, and authorized), Confidentiality (information designated as confidential is protected), and Privacy (personal information is collected, used, retained, disclosed, and disposed of in conformity with commitments).
Security is the only required criterion — all others are optional depending on the company's commitments to customers. Most SaaS companies achieve SOC 2 certification on Security and Availability at minimum.
There are two types of SOC 2 reports: Type I assesses whether controls are designed and implemented appropriately at a single point in time (snapshot). Type II assesses whether controls operated effectively over a period of time, typically 6 or 12 months — far more meaningful and what most enterprise buyers require.
Achieving SOC 2 Type II requires significant investment: engaging an AICPA-licensed auditor, implementing evidence collection systems, remediating control gaps (often 3–6 months of work), and undergoing the audit period. Compliance automation platforms (Vanta, Drata, Secureframe, Laika) have dramatically reduced the cost and time to SOC 2 by automating evidence collection and control monitoring.
SOC 2 reports are routinely requested by enterprise buyers during vendor security reviews and are often a gate to signing large contracts. Companies without SOC 2 risk losing enterprise deals to compliant competitors.
FAQs
How long does it take to achieve SOC 2 Type II certification?
The typical timeline is 9–15 months from starting implementation to receiving a Type II report. Preparation (gap assessment, control implementation, policy documentation) takes 3–6 months. The observation period (typically 6–12 months) follows. The audit itself takes 4–8 weeks. Compliance automation platforms can reduce preparation time by 40–60%.
What is the difference between SOC 1 and SOC 2?
SOC 1 (formerly SAS 70) focuses on internal controls over financial reporting — relevant for service providers whose controls affect their customers' financial statements (payroll processors, claims processors). SOC 2 focuses on technology and data security controls relevant to customer data protection. SaaS companies need SOC 2; payroll processors or fund administrators may need both.
Is SOC 2 certification required by law?
No — SOC 2 is voluntary. However, it's effectively required commercially for any SaaS company seeking enterprise contracts, because enterprise buyers require independent validation of security practices. Some regulated industries (financial services, healthcare) effectively mandate it through customer contract requirements or regulatory guidance even if not statutory.
