A SOC 2 Type 2 report is an independent audit that evaluates how well a company’s internal controls protect customer data over an extended period, typically six to twelve months. It’s issued by a licensed CPA firm and based on standards set by the American Institute of Certified Public Accountants (AICPA). If a vendor, client, or partner has asked you for one, they want proof that your security practices aren’t just designed well on paper but actually work consistently over time.
What the Report Actually Covers
A SOC 2 Type 2 report is built around the AICPA’s Trust Services Criteria, which define five categories of controls a company can be evaluated on:
- Security: Protection against unauthorized access to systems and data. This is the only category required in every SOC 2 report.
- Availability: Whether systems are operational and accessible as promised in service agreements.
- Processing Integrity: Whether system processing is complete, accurate, and authorized.
- Confidentiality: Whether information designated as confidential is properly protected.
- Privacy: Whether personal information is collected, used, retained, and disclosed in line with the organization’s privacy commitments.
Your organization chooses which categories to include based on the services you provide and what your customers care about. A cloud storage company would almost certainly include availability and confidentiality. A payroll processor handling employee Social Security numbers would likely include privacy. The more categories you include, the broader the audit scope and the higher the cost.
How Type 2 Differs From Type 1
The key distinction is time. A SOC 2 Type 1 report is a snapshot. It evaluates whether your controls are properly designed as of a single date. A Type 2 report goes further by testing whether those controls actually worked over an observation period of three months to a full year.
The difference shows up concretely in how auditors collect evidence. For a Type 1, an auditor might ask for one example of a completed background check for a recent hire. For a Type 2, the auditor looks at the entire population of new hires throughout the observation period, selects a sample, and verifies that background checks were completed for each one. This sampling approach applies across every control being tested: access reviews, change management approvals, incident response procedures, and so on.
Because of this, a Type 2 report carries significantly more weight with customers and prospects. It demonstrates that your controls aren’t just theoretical. They held up under real operating conditions for months. Many enterprise buyers and regulated industries specifically require a Type 2 report before they’ll sign a contract or share sensitive data with a vendor.
What the Audit Looks Like
A SOC 2 Type 2 audit unfolds in two main phases: the observation period and the audit itself. The observation period (also called the review window or lookback period) runs for a minimum of three months and up to a full year. During this time, your organization operates under the controls you’ve put in place, and you collect evidence that those controls are functioning. After the observation period closes, the CPA firm reviews the evidence, conducts testing, and produces the final report.
From start to finish, a Type 2 report typically takes six months to a year to complete. That timeline includes the observation period plus the auditor’s fieldwork and report writing. By comparison, a Type 1 report can be completed in roughly five weeks to two months since it only evaluates a single point in time.
Many organizations pursue a Type 1 first to validate their control design, then move to a Type 2 once they’re confident the controls can hold up over several months. Others skip directly to Type 2 if they already have mature security practices in place.
What You Need to Have in Place
Preparing for a SOC 2 Type 2 audit requires documented policies, functioning controls, and evidence that those controls are operating consistently. Here’s what auditors typically expect to see:
Formal, documented policies. You need written policies covering access control, data management and classification, incident response, change management, and hiring and onboarding. These policies must align with the Trust Services Criteria you’ve selected, be accessible to all employees, and be formally acknowledged by staff. Auditors will check that policies are reviewed and updated regularly, not just created and forgotten.
Access controls. Strong user authentication is essential, including multi-factor authentication and enforced password standards. You’ll need to show that user access privileges are reviewed regularly and that only authorized individuals can reach sensitive systems and data.
Incident response and disaster recovery plans. Your plan should cover how you identify, contain, eradicate, and recover from security incidents or data breaches. Auditors want to see that you’ve tested the plan, not just written it.
Change management processes. Any changes to system configurations, software, or patches need to be tracked, reviewed, and documented. Auditors will sample changes made during the observation period to verify that your approval and review process was followed each time.
Segregation of duties. Critical functions need to be divided among different people so that no single individual has unchecked control over sensitive processes. For example, the person who writes code shouldn’t be the same person who approves its deployment to production.
A risk assessment. Before the audit begins, you should conduct a thorough assessment of the threats and vulnerabilities that could affect your systems and data. This informs which controls you prioritize and helps demonstrate to auditors that your security program is risk-driven rather than ad hoc.
How Much It Costs
The audit itself typically runs between $15,000 and $50,000 or more, depending on several factors. The number of Trust Services Criteria you include, the complexity of your infrastructure, and the size of your organization all push the price up or down. Companies that already have a compliance framework in place (like ISO 27001 or GDPR controls) can often skip redundant steps, which reduces both preparation time and cost. Organizations with overlapping certifications may see combined costs drop by 40% to 60%.
Companies starting from scratch face higher total costs because they need to build policies, implement controls, and train staff before the audit can even begin. Compliance automation platforms like Vanta, Drata, and Secureframe can reduce implementation time by 50% to 70% and compress audit preparation from roughly three months down to a few weeks. These tools continuously monitor your controls, collect evidence automatically, and flag gaps before the auditor arrives.
Keep in mind that the audit fee is only part of the total investment. Factor in the cost of any new security tools, staff time spent gathering evidence, and potential remediation work if gaps are found during the observation period.
Who Needs One
SOC 2 Type 2 reports are not legally required for most businesses, but they’ve become a practical requirement for any company that handles customer data and sells to other businesses. SaaS companies, cloud infrastructure providers, data processors, managed IT service providers, and healthcare technology vendors are among the most common organizations that pursue one.
The demand usually comes from customers. Enterprise procurement teams, especially in financial services, healthcare, and technology, routinely ask vendors for a current SOC 2 Type 2 report during due diligence. Without one, you may lose deals or face longer sales cycles as prospects try to evaluate your security posture through questionnaires and custom audits instead.
SOC 2 reports are not public documents. You share them under NDA with customers, prospects, and partners who request them. The report includes a detailed description of your systems, the controls tested, the auditor’s test procedures, and the results, including any exceptions (instances where a control didn’t operate as intended). Exceptions don’t automatically mean you “fail” the audit, but they are visible to anyone who reads the report, and significant or repeated exceptions will raise concerns.
How Often You Need to Renew
A SOC 2 Type 2 report does not expire in a formal sense, but it covers a specific observation period. Once that period ends, the report grows stale. Most organizations renew annually, with each new report covering the subsequent twelve-month window. Customers typically expect to see a report that covers a period ending within the last twelve months, so letting your audit cycle lapse can stall deals just as effectively as not having one at all.
After your first report, subsequent audits tend to be less disruptive. Your policies and controls are already in place, your team knows the evidence collection process, and the auditor has a baseline from the prior year. The cost and effort typically decrease after the initial engagement, assuming you’ve maintained your controls consistently.
