Your Guide to SOC 2 Compliance and the Audit Process

Why Your Enterprise Customer Is Demanding a SOC 2 Report

Enterprise buyers use SOC 2 reports to verify that a service organization's security controls are appropriately designed and, in the case of a Type II report, have operated effectively over a defined period. Security controls include measures such as access restrictions, employee access reviews, vulnerability management, and incident response procedures.

For your customers, particularly larger enterprises, relying on your services means extending their own security perimeter. They need formal assurance that you will not introduce a weak link into their supply chain.

SOC 2 Unblocks Deals by Proving You Protect Customer Data

Your customer’s security and vendor management teams are tasked with managing risk. They cannot simply take your word that your systems are secure. A SOC 2 report, issued by an independent Certified Public Accountant (CPA) firm, provides an objective, third-party opinion on the effectiveness of your security program. It replaces lengthy security questionnaires and subjective conversations with a standardized, trusted artifact that satisfies their due diligence requirements.

It Is a Contractual Requirement, Not a Legal Mandate

Unlike regulations like HIPAA or PCI DSS, SOC 2 is not mandated by any law. It was developed by the American Institute of Certified Public Accountants (AICPA) as a voluntary framework. Its power comes from the market. As data breaches have become more common, enterprise companies have made SOC 2 compliance a standard contractual requirement for their technology vendors, especially SaaS providers, MSPs, and data centers.

A SOC 2 Audit Examines Your Controls Against Five Core Principles

The audit itself is an examination of your internal controls against a set of principles defined by the AICPA. These are known as the Trust Services Criteria (TSC), and they provide the framework for the entire process.

The AICPA's Five Trust Services Criteria Define the Scope

The audit is structured around five distinct criteria. Your business model and the promises you make to your customers determine which of these criteria you need to include in your report.

1. Security: Protection of information and systems against unauthorized access and disclosure.
2. Availability: Accessibility of information and systems as stipulated by a contract or service level agreement (SLA).
3. Processing Integrity: The completeness, validity, accuracy, and timeliness of system processing.
4. Confidentiality: Protection of information designated as confidential.
5. Privacy: The collection, use, retention, and disposal of personal information.

Security Is the Only Mandatory Criterion for Every Audit

The Security criterion, also called the Common Criteria, is the foundation of every SOC 2 audit and is the only one that is mandatory. It covers the essential elements of a security program, including risk assessment, access controls, and monitoring. For many SaaS companies, a report covering only the Security criterion is sufficient to meet customer demands.

You Choose Which Other Criteria to Include Based on Your Services

You select the additional criteria based on the nature of your service. If you provide critical infrastructure and have uptime SLAs, you should include Availability. If you handle sensitive data like financial records or intellectual property, you should include Confidentiality. Processing Integrity is for services that perform transactions or calculations, while Privacy is for those handling personally identifiable information (PII).

What Is the Difference Between a SOC 2 Type I and Type II Report?

A Type I report describes your controls, while a Type II report proves they actually work. The distinction is critical, as most customers will only accept a Type II report as valid proof of your security posture.

Type I Shows Your Controls Are Designed Correctly at One Moment

A Type I audit provides a snapshot. The auditor examines your security policies, procedures, and system configurations on a specific date to determine if they are suitably designed to meet the relevant Trust Services Criteria. It answers the question: "Do you have the right controls in place?" It is a good first step but offers limited assurance that those controls are followed day-to-day.

Type II Proves Your Controls Have Worked Over Several Months

A Type II audit provides a much higher level of assurance. The auditor observes your controls in operation over a period of time, typically three to twelve months. They test the operating effectiveness of your controls by requesting evidence samples.

To test operating effectiveness, auditors request evidence like termination lists. They then cross-reference HR records with system access logs to confirm access was revoked per policy.

This proves your controls are not just designed well, but are also functioning consistently.

Why Most Customers Will Only Accept a Type II Report

Enterprise buyers need assurance that your security is a continuous practice, not a one-time project. A Type I report shows you wrote a good plan. A Type II report shows you executed that plan consistently under real-world conditions for months. For this reason, the Type II report has become the market standard for vendor due diligence.

Follow These Five Phases for a Successful SOC 2 Audit

The path to a SOC 2 report is a structured project managed in collaboration with a licensed CPA firm. The process moves from high-level strategy to detailed evidence gathering and formal testing.

1: Define the Audit Scope with Your Auditor

You begin by deciding which systems and Trust Services Criteria will be included in the audit. This is a critical business decision. Scoping too broadly creates unnecessary work, while scoping too narrowly may produce a report that doesn't satisfy your customers. You will work with your chosen audit firm to define a scope that accurately reflects your services.

2: Conduct a Readiness Assessment to Find Gaps

Before the formal audit begins, perform a readiness assessment. This is a pre-audit that compares your existing controls against the SOC 2 requirements. It identifies gaps in your policies, procedures, and technical configurations, giving you a clear roadmap of the remediation work needed to pass the real audit.

3: Remediate Gaps and Collect Evidence

This is where the bulk of the work happens. Your team will write missing policies, implement new security tools, configure systems, and document procedures to close the gaps identified in the readiness assessment. You will also begin collecting evidence to prove your controls are operating, such as system logs, change management tickets, and employee training records.

For example, if the assessment finds that former employees still have access to company systems, your IT team needs to revoke that access and examine why the offboarding process failed. If your incident response policy requires annual testing but no test has taken place, the team needs to conduct the exercise, document the results, and address any weaknesses identified.

Evidence collection should happen alongside these activities, particularly for a Type II examination. Writing a policy or correcting a security configuration does not prove that the control operated effectively throughout the examination period. Your team needs dated records showing when the required activities took place, who performed them, and how the organization addressed any exceptions.

4: The CPA Firm Conducts the Formal Audit

Once you are ready, the formal audit window opens. For a Type II audit, this is the 3- to 12-month observation period. During this time, your auditor will request evidence and perform tests to verify your controls are working as designed. This phase involves interviews with your team and detailed reviews of the evidence you have collected.

5: The Auditor Issues Your Final SOC 2 Report

After the observation period closes and all testing is complete, the auditor will write and issue your official SOC 2 report. The report includes the auditor's opinion on the effectiveness of your controls, a description of your systems, and the results of the auditor's tests. This is the document you will share with your customers.

How Much Does a SOC 2 Audit Actually Cost in 2026?

A first-year SOC 2 Type II for a small to mid-size company typically costs between $25,000 and $70,000. If you are a large enterprise, expect costs to exceed $200,000.

Budget for Audit Fees, Platform Subscriptions, and Readiness Consulting

Your total cash outlay will be spread across three main categories:

• Audit Fees: The fee paid to the CPA firm. A Type I audit costs between $7,500 and $15,000, while a Type II audit ranges from $12,000 to over $100,000, depending on scope and complexity.
• Readiness & Consulting: Fees for a readiness assessment or for consultants who help you prepare for the audit.
• Platform & Tooling: The subscription cost for a compliance automation platform and any new security tools (like endpoint detection or vulnerability scanners) required to meet control requirements.

The Hidden Cost Is Your Own Team's Time for Remediation and Policy Writing

The most frequently underestimated cost is the internal labor required. While compliance software can automate evidence collection, it cannot write your security policies, configure your cloud environment, or manage the audit project. Your engineers, IT staff, and leadership will spend significant time on remediation, documentation, and interacting with the auditor. This internal effort often represents the largest single component of the total cost of compliance.

A Complete First-Year SOC 2 Budget Ranges from $25,000 to $70,000+

When you combine audit fees, platform costs, and the internal time investment, a realistic first-year budget for a small or mid-market company falls in the $25,000 to $70,000 range. Ongoing annual renewal costs, which include the repeat audit fee and platform subscription, typically range from $18,000 to $120,000.

How Long Does the SOC 2 Process Take?

The timeline depends entirely on whether you are pursuing a Type I or Type II report. The primary driver of the Type II timeline is the mandatory multi-month observation period.

Expect a Few Months for a Type I Report

Because a Type I audit examines your controls at a single point in time, the process is much faster. Including readiness and remediation, you can typically complete a Type I audit in a few months.

Plan for 6 to 15 Months to Complete a Full Type II Audit

A Type II audit is a much longer engagement. The total timeline includes the initial readiness and remediation work, plus the 3- to 12-month observation period itself. A realistic end-to-end timeline, from project kickoff to receiving your final report, is between six and fifteen months.

What Happens After the Audit?

Receiving your SOC 2 report is a major milestone, but it is the beginning of an ongoing process, not the end of a one-time project. Compliance is a continuous state that must be maintained.

SOC 2 Requires Continuous Monitoring

Your SOC 2 report is valid for twelve months. During that time, you must ensure the controls described in the report continue to operate effectively. This requires a program of continuous monitoring to detect and respond to any control failures or security incidents.

Prepare for the Annual Renewal Audit to Maintain Compliance

To keep your SOC 2 status active, you must undergo a renewal audit every year. The process is similar to your initial audit, covering a new 12-month observation period. Preparation for the next audit should begin as soon as the current one ends.

How Auditor Expectations Are Evolving for 2026 and Beyond

While the core SOC 2 framework is stable, auditor expectations are constantly evolving. For 2026, auditors are placing greater emphasis on continuous monitoring over point-in-time evidence. They also have heightened expectations for documented vendor risk management programs and the implementation of modern security architectures based on zero-trust principles.

How SOC 2 Compares to Other Common Frameworks

SOC 2 is one of several frameworks your customers might ask about. Understanding the key differences helps you respond to their specific needs.

SOC 2 vs. ISO 27001: Attestation Report vs. Management System Certification

SOC 2 results in an attestation report on the effectiveness of your controls. ISO 27001 is a certification that your organization has implemented a formal Information Security Management System (ISMS). While their controls overlap significantly, ISO 27001 is more focused on the overarching management process, and it is the dominant standard outside of North America.

SOC 2 vs. HIPAA: Demonstrating Technical Safeguards for Healthcare Data

HIPAA is a U.S. law governing the protection of health information. There is no formal HIPAA certification. A SOC 2 report that includes the Security, Confidentiality, and Privacy criteria can be used to demonstrate to healthcare clients that you have implemented the technical safeguards required by the HIPAA Security Rule.

SOC 2 vs. SOC 1 and SOC 3: Different Audiences and Levels of Detail

• SOC 1: Focuses on controls relevant to a client's financial reporting. It is for service organizations that impact their customers' financial statements, like payroll processors.
• SOC 3: A high-level, publicly shareable summary of the SOC 2 report. It provides the auditor's opinion but does not include the detailed description of controls or test results, making it suitable for marketing purposes.

Turn a Compliance Burden into a Repeatable Process

Achieving SOC 2 compliance for the first time is a heavy lift, but it can be systematized. The key is to recognize that compliance is a function of both technology and expertise.

Compliance Software Automates Evidence Collection, Not Strategy

Modern compliance platforms are essential for managing a SOC 2 program. They connect to your cloud services and security tools to automate the collection of technical evidence, saving hundreds of hours of manual work. However, the platform is just a tool. It cannot define your audit scope, write your security policies, or manage the relationship with your auditor. That requires human expertise.

Choose Your Model: Empower Your Internal Team or Outsource the Work

You have two primary options for supplying the necessary expertise. You can dedicate your own internal team to manage the process, using a platform like Sable to make them more efficient. This turns compliance into an internal operational responsibility.

Alternatively, you can convert that unpredictable internal labor cost into a fixed external one. A firm like SubRosa can provide the security and compliance experts who manage the entire process for you within the Sable platform. This approach frees your internal team to focus on your core product while ensuring the audit is managed by specialists. The right choice depends on your team's existing expertise, bandwidth, and budget.
