SOC 2: Definition, Importance, Cost, Audit and Trust Services Criteria

SOC 2 feels like a checkbox until a customer asks for proof. This guide explains what SOC 2 compliance is, who governs the framework, why it matters for SaaS, the Trust Services Criteria, how SOC 2 audits work, Type 1 vs Type 2 reports, typical costs, automation, and common audit failures. 

What is SOC 2 in cybersecurity? 

SOC 2 in cybersecurity is an AICPA-defined audit and reporting framework used by a service organization (typically SaaS, cloud, and other service providers) to prove that its security controls and internal control environment protect customer data and systems against defined Trust Services Criteria, and many buyers also evaluate managed soc service providers as third-party security partners that help operate monitoring, detection, and response controls that support the same security outcomes SOC 2 expects. 

A SOC 2 engagement produces a SOC 2 report (a SOC report) based on an independent audit (often called a SOC 2 audit) that evaluates controls relevant to one or more of the five trust service categories: Security, Availability, Processing Integrity, Confidentiality, and Privacy. 

SOC 2 has two main report forms by soc 2 type: 

• Type 1: evaluates whether controls are suitably designed at a point in time. 

• Type 2 (also written as type ii or type 2): evaluates whether controls are suitably designed and operating effectively over a defined period (the practical “audit period” concept).

What Is SOC 2 Compliance? 

SOC 2 compliance is the state where a service organization can provide a SOC 2 report from an independent audit process showing that its information security and data security controls meet the AICPA Trust Services Criteria (Security, Availability, Processing Integrity, Confidentiality, Privacy), and many teams support those controls by using the best soc as a service as an outsourced security operations function that provides continuous monitoring, alert triage, and incident response aligned to SOC 2 expectations. 

Why is SOC 2 important for SaaS companies? 

SOC 2 is important for SaaS companies because it provides independent, AICPA-based assurance that the SaaS provider has designed and operated controls that protect customer data and the systems that process it. A SOC 2 report is specifically intended to give customers and other stakeholders detailed assurance over controls relevant to the Trust Services Criteria.  

For SaaS, this matters for three concrete cybersecurity reasons: 

• It operationalizes a credible security posture for buyer scrutiny. Enterprise procurement and security teams treat a SOC 2 report as evidence that the SaaS vendor’s control environment is not self-asserted; it has been examined against defined criteria under the AICPA SOC framework (the “type of SOC” relevant to security, availability, processing integrity, confidentiality, and privacy). 

• It matches SaaS risk reality. SaaS companies routinely host, process, or transmit customer data. SOC 2 is structured to evaluate controls over the systems a service organization uses to process users’ data, which directly maps to SaaS threats like unauthorized access, misconfiguration, and availability-impacting incidents, and a soc as a service vendor can support this by running the operational security function that monitors logs, investigates alerts, and escalates incidents so the underlying controls remain effective in practice. 

• It is commonly a sales and vendor qualification gate. Many customers will not onboard a SaaS vendor without third-party assurance of security controls; a SOC 2 report is often used in vendor due diligence to reduce reliance on questionnaires and self-reported claims. 

SOC 2 also helps SaaS teams avoid confusion with SOC 1, which is designed for controls relevant to financial reporting rather than cybersecurity assurance. 

Who governs the SOC 2 framework? 

The SOC 2 framework is governed by the American Institute of Certified Public Accountants (AICPA), formally known as the Institute of Certified Public Accountants, through its System and Organization Controls 2 standards. 

The AICPA is responsible for: 

• Defining the SOC 2 criteria, including the Trust Services Criteria that form the foundation of the compliance framework.

• Establishing the SOC 2 standards used during a SOC 2 audit process.

• Regulating how Type 1 report and Type 2 report examinations are performed and documented.  

• Overseeing the structure of types of SOC reports, including SOC 1, SOC 2, and SOC 3, and clarifying the difference between SOC frameworks.

• Setting the requirements for SOC 2 attestation, ensuring audits are conducted by licensed CPA firms under uniform professional guidance.

Under AICPA governance, SOC 2 remains a voluntary compliance standard, meaning organizations are not legally mandated to adopt it, but many must meet SOC 2 compliance requirements to satisfy customer security expectations and contractual obligations, and a managed security service provider can help by operating day-to-day security monitoring and response controls that support those expectations and generate consistent evidence for audits.

What Are the SOC 2 Trust Services Criteria? 

SOC 2 Trust Services Criteria are the AICPA-defined control criteria used in a SOC 2 examination to evaluate and report on controls at a service organization relevant to the security, availability, processing integrity, confidentiality, and privacy of the systems that process users’ data. 

The five Trust Services Criteria categories are:  

• Security (the “Common Criteria” baseline): Controls that reduce the risk of unauthorized access, unauthorized disclosure, and system misuse. 

• Availability: Controls that support system availability for operation and use as committed or agreed. 

• Processing integrity: Controls that support system processing that is complete, valid, accurate, timely, and authorized.

• Confidentiality: Controls that protect information designated as confidential (for example, customer data, trade secrets, or sensitive business data) from unauthorized disclosure. 

• Privacy: Controls that govern the collection, use, retention, disclosure, and disposal of personal information in line with commitments and criteria. 

What is SOC 2 automation? 

SOC 2 automation is the use of software and integrations to streamline how an organization achieves SOC 2 compliance and maintains it continuously, by (a) continuously monitoring controls, (b) automatically collecting audit evidence, and (c) keeping security program artifacts like security policies and control status organized for an auditor’s review, and a cloud based soc as a service can complement this by delivering remote, always-on monitoring and alert response that feeds ongoing control evidence into the audit trail. 

How Much Does SOC 2 Compliance Cost? 

SOC 2 compliance cost depends on the SOC 2 requirements in scope, the audit process, and whether you need a SOC 2 Type II report (also written as SOC 2 Type 2 report / type ii report) versus a Type 1 report; published estimates for audit fees and readiness commonly fall into these ranges.  

• SOC 2 Type 1 report audit fee: $5,000–$20,000 ≈ ₹4.15 lakh–₹20.75 lakh (approx.) 

• SOC 2 Type 2 (SOC 2 Type II) report audit fee: $7,000–$150,000 ≈ ₹5.81 lakh–₹1.245 crore (approx.) 

• SOC 2 readiness assessment (commonly separate): $10,000–$17,000 ≈ ₹8.30 lakh–₹14.11 lakh (approx.)

What Is a SOC 2 Audit? 

A SOC 2 audit (also written as SOC2) is an independent SOC audit where a licensed audit firm examines a service organization’s controls against the AICPA trust service principles (Trust Services Criteria) to determine whether the organization’s controls are suitably designed and, when applicable, operating effectively, and many organizations support those controls by using managed soc as a service as an outsourced security operations capability that continuously monitors events, investigates alerts, and documents response actions in a way auditors can test. 

A SOC 2 audit evaluates controls mapped to the Trust Services Criteria for Security, Availability, Processing Integrity, Confidentiality, and Privacy (the control baseline used to assess whether a service organization is SOC 2 compliant). 

What Are Common SOC 2 Audit Failures and Exceptions? 

Common SOC 2 audit failures and exceptions are specific instances where a control did not operate as designed, or where the organization cannot produce consistent evidence that the control operated during the audit period, which can lead to exceptions being documented in the final report.  

The following points are related to common SOC 2 audit failures and exceptions. 

• Access reviews not completed on schedule, or completed without auditable evidence such as reviewer identity, approval, and timestamps. 

• Delayed or incomplete offboarding where terminated or role-changed users retain access beyond the organization’s stated control window. 

• Change management gaps such as production changes lacking documented approval, testing evidence, or a traceable ticket trail. 

• Logging and monitoring evidence gaps where required logs, alerts, or investigations exist in practice but are not retained, not reviewable, or not tied to the defined control. 

• Vendor and third-party risk controls not followed including missing vendor reviews, missing tracking of critical vendors, or inconsistent due diligence records. 

• Policy governance breakdowns such as policies not approved, not reviewed on the required cadence, or controls not matching the written policy (conflicting evidence).  

• Security awareness and training lapses where required training is not completed by all scoped personnel or completion evidence is incomplete. 

• Scope and system boundary inconsistencies where the described in-scope systems and processes do not align with what evidence shows was actually operated or monitored. 

What Is the Difference Between SOC 2 Type 1 and Type 2? 

What is the average SOC 2 audit cost? 

The average SOC Two audit cost (auditor fee only) is approximately $40,000 for a SOC 2 Type II audit (typical range $20,000–$60,000), while a SOC 2 Type One audit averages around $20,000 (range $15,000–$25,000). 

Converted at an approximate rate of ₹83 per USD, the average costs are: 

• SOC 2 Type II audit: $20,000–$60,000 ≈ ₹16.6 lakh–₹49.8 lakh

• SOC 2 Type I audit: $15,000–$25,000 ≈ ₹12.4 lakh–₹20.8 lakh

SOC 2 remains a voluntary compliance framework, but many organizations need a SOC Two report to satisfy customer security expectations and vendor risk requirements.
