SOC 2 Compliance Audit and Certification: What You Need to Know

What Is SOC 2 Compliance?

System and Organization Controls (SOC) 2 Compliance is an organization’s adherence to the American Institute of Certified Public Accountants (AICPA) Trust Services Criteria, a framework that covers: 

• Security
• Availability
• Processing integrity
• Confidentiality
• Privacy

SOC 2 applies to service organizations that store, process, or manage customer data, such as software-as-a-service providers, cloud platforms, financial technology companies, healthcare technology providers, and managed service providers.

Security is the main requirement for every SOC 2 audit. The other four criteria depend on the services provided, customer expectations, and contractual commitments. SOC compliance is an ongoing process, not a one-time achievement, and it doesn’t include a physical certificate. Instead, a CPA firm issues an attestation report as part of the AICPA’s broader SOC Suite of Services.

Why SOC 2 Compliance Is Important

SOC 2 compliance is important because it gives customers independent assurance about how an organization manages the data it handles. Enterprise buyers increasingly request current SOC 2 reports before signing a vendor contract, especially in financial services, healthcare, and technology. 

Gartner’s 2026 Audit Plan Hot Spots report found that regulatory compliance and cybersecurity vulnerabilities are expected to be among the most common risk areas in internal audit plans for 2026, with 97% and 96% of respondents including them, respectively. This broader risk focus helps explain why SOC 2 requirements matter. The audit process also ensures companies formalize security practices.

What Are the SOC 2 Compliance Requirements?

SOC 2 compliance requirements translate the Trust Services Criteria into testable practices across five operational areas. Every audit includes security controls, while the remaining criteria are added when relevant to customer commitments. Auditors evaluate these requirements through written policies and evidence that the organization implements them.

1. Security controls and policies

Security controls and policies establish the baseline protections auditors test first, since security is the only mandatory requirement. This includes firewalls, encryption, and written policies with clear ownership, which are applied consistently rather than drafted solely for the audit.

Auditors will sample specific controls, such as firewall or encryption settings, and ask for evidence that the control operated during the review period rather than accepting the policy document alone.

2. Access control and user management

Access control and user management requirements focus on limiting who can reach sensitive systems. This covers least-privilege access, multi-factor authentication, and proof that access is removed promptly when an employee changes roles or leaves.

A common gap is delayed offboarding, where access stays active for days or weeks after someone leaves. Auditors will flag this as a control failure even if no misuse occurred.

3. Risk management and security monitoring

Risk management and security monitoring require an ongoing process to identify and track weaknesses, not a one-time review. This includes a formal Vulnerability Management program that prioritizes finding weaknesses before attackers exploit them.

Auditors look for a documented cadence, such as monthly scans or continuous monitoring alerts, along with evidence that the organization tracked flagged issues to resolution rather than leaving them open.

4. Incident response and business continuity

Incident response and business continuity requirements ask for a documented plan describing how the organization detects, contains, and recovers from an incident, backed by detection tooling such as Extended Detection and Response (XDR) that correlates suspicious activity across the environment.

Auditors often ask whether the plan has been tested, such as through a tabletop exercise, since an untested plan is difficult to demonstrate as effective. This connects the written response plan to real-world readiness.

5. Evidence collection and documentation

Evidence collection and documentation requirements cover the proof auditors need that controls operated as described, including logs, access review records, and signed acknowledgments. Missing evidence is one of the most common reasons audits stall.

Gaps often surface for controls that ran correctly but were never recorded, since auditors can assess only what’s documented, not what the team remembers doing.

How Does the SOC 2 Audit Process Work?

The SOC 2 compliance audit process works through six stages, from defining scope to receiving the final report.

1. Define the scope of the SOC 2 audit

Defining the audit scope identifies which systems and Trust Services Criteria the audit will cover, shaping which controls need evidence. This early decision also determines the engagement’s size and SOC 2 audit cost, since a wider scope means more controls to test.

2. Select a SOC 2 auditor

Selecting an auditor means choosing a licensed CPA firm with SOC 2 experience in the organization’s industry that can flag likely gaps before fieldwork begins. Organizations often compare proposals from a few firms and weigh their experience with similarly-sized companies, since inexperienced auditors can slow the process down.

3. Assess existing controls

Assessing existing controls tests whether current security measures actually hold up before the auditor does. A SOC 2 audit examines whether your controls are both suitably designed and operating effectively, not just whether a policy document exists. Vulnerability scans and access reviews check the paperwork side; they rarely test whether a control resists an actual attempt to bypass it.

Group-IB Penetration Testing simulates real attack techniques against the specific systems and controls in your SOC 2 scope, network segmentation, authentication mechanisms, privileged access paths, and the boundary controls protecting customer data, surfacing exploitable weaknesses a policy review alone would miss. Where this connects directly to SOC 2 evidence: findings map to the Common Criteria control areas auditors test under CC6 (logical and physical access controls) and CC7 (system operations and change management), giving you documented proof a control was actually tested, not just described.

4. Remediate control gaps

Remediating control gaps fixes the weaknesses found during assessment before the formal audit period begins, from patching software to rewriting access policies, and it usually takes longer than teams expect. 

Underestimating this step often delays the audit start date, since some fixes, such as rolling out multi-factor authentication organization-wide, take weeks to complete.

5. Collect audit evidence

Collecting audit evidence gathers the logs and documentation that prove each control operated as intended. For a Type II report, this must span the entire observation period, not just a snapshot near the assessment date. Centralizing evidence collection from the start helps keep the audit trail continuous.

6. Complete the audit and receive the report

The CPA firm completes the audit by reviewing the evidence, testing the controls, and issuing a report with its opinion, a system description, and, for Type II, the results of testing over the review period. 

This final stage can take several weeks, since the auditor needs time to review collected evidence before finalizing the report.

How Long Does SOC 2 Compliance Take?

SOC 2 compliance audit timelines depend on the report type. A Type I audit can often be completed in weeks, since it evaluates whether controls are designed appropriately at a single point in time. 

A Type II audit takes considerably longer, since it tests whether controls operated effectively over an observation period, typically several months to a year. First-time organizations should also budget time beforehand for gap remediation.

How Much Does a SOC 2 Audit Cost?

SOC 2 audit costs vary based on the Trust Services Criteria in scope, the size of the systems tested, and whether the organization pursues Type I or Type II. Additional drivers include readiness work beforehand, such as remediating gaps or building documentation from scratch. 

It’s sometimes searched as SOC 2 certification cost even though it’s the audit itself, not a certificate, that generates the expense. Organizations typically request quotes directly from CPA firms since pricing depends on scope and starting maturity.

What Is a SOC 2 Report?

A SOC 2 report is the formal document a CPA firm issues after the audit, describing the system tested and the auditor’s findings. 

It includes management’s assertion about the controls in place and the auditor’s opinion on whether those controls meet the relevant Trust Services Criteria, with Type II going further to test whether controls operated effectively over the observation period.

SOC 2 Type I vs. Type II

SOC 2 Type I and Type II differ in what they test and over what timeframe. 

Type I evaluates whether controls are designed appropriately at a single point in time, while Type II evaluates whether those same controls operated effectively over an extended period. 

Most organizations start with a Type I report to establish a baseline, then move to Type II for the sustained assurance enterprise customers typically expect.

How to Prepare for a SOC 2 Audit

Effective SOC 2 preparation combines control assessment, technical testing, documented ownership, and continuous evidence collection. Investing in this stage can reduce the overall SOC 2 certification cost, since fewer gaps mean less rework once formal fieldwork begins.

1. Identify compliance gaps

Identifying compliance gaps compares current controls against the in-scope Trust Services Criteria and flags what’s missing. This often surfaces gaps in endpoint visibility, where a formal Endpoint Detection and Response (EDR)capability is missing or inconsistent. 

A structured gap assessment generally maps each criterion to existing controls and highlights missing documentation, technology, or processes before the auditor arrives.

2. Establish and document security controls

Establishing and documenting security controls turns informal practices into written policy auditors can review. Undocumented controls, even well-run ones, are difficult for an auditor to test. Each policy should name a control owner and a review cadence, since an auditor testing least-privilege access, for example, needs to see who approves access requests and how often those approvals are reviewed.

3. Implement continuous monitoring

Implementing continuous monitoring moves teams from periodic checks to ongoing visibility, since a Type II audit tests controls over time. Gaps found in a point-in-time review tend to reappear if monitoring isn’t sustained. Teams relying on manual, ad hoc checks may struggle to produce consistent evidence across the observation period, which is why automated alerting and logging tend to hold up better under audit.

4. Organize audit evidence

Organizing audit evidence sets up a central way to store logs and policy records as they’re generated, rather than reconstructing them later. Auditors move faster when evidence traces cleanly to a specific control. 

A shared evidence repository saves significant time during fieldwork compared to searching across email threads, spreadsheets, and individual team members’ files.

5. Conduct an internal readiness assessment

An internal readiness assessment provides a structured review of people, processes, and technology before the formal audit. Group-IB’s SOC Consulting services support this stage directly, helping organizations assess security maturity and build a roadmap ahead of the SOC 2 compliance audit rather than reacting to findings after the fact.

Who Can Perform a SOC Audit?

Only a licensed CPA firm can perform a SOC audit and issue the resulting report, since SOC compliance reports are attestation engagements governed by AICPA auditing standards. 

Security consultants can support preparation work, such as gap assessments and readiness checks, but they cannot issue the report itself. Organizations should treat these as two separate engagements: preparation with a security partner followed by formal attestation with a CPA firm.

SOC 2 Audit Checklist

The checklist below summarizes the core steps from the sections above and provides your security team with a quick reference for meeting SOC 2 requirements before scheduling an audit.

• Define the systems and criteria in scope.
• Run an internal readiness assessment.
• Document security policies and control ownership.
• Test existing controls, including penetration testing.
• Remediate identified gaps.
• Set up continuous monitoring.
• Organize evidence in a central location.
• Select a licensed CPA firm and confirm the timeline.

What Happens After a SOC 2 Audit?

After a SOC 2 audit, the organization receives a report stating the auditor’s opinion, which can be unqualified, qualified, or note specific exceptions where a control didn’t operate as intended. 

Organizations typically share a clean report with customers and prospects under NDA to support vendor due diligence, and remediate exceptions before the next cycle. 

Since a Type II report covers a defined observation period, most organizations repeat the process annually to keep a current report on hand.

SOC 1 vs. SOC 2

SOC 1 and SOC 2 differ in what they evaluate and who typically relies on the report. The table below compares the two across scope, governing criteria, and typical use case.

Fintech platforms that both process transactions and store customer data often need both reports.

Closing the Control Gaps a SOC 2 Compliance Audit Will Expose

A SOC 2 audit assesses whether controls functioned effectively over the review period, not just whether they exist on paper. The Common Criteria for system operations require ongoing monitoring for anomalies and a documented response to confirmed security events. Auditors will ask for alert records and response timelines to prove this monitoring is happening. Any gaps in detection or lack of a documented escalation path will be highlighted as issues in the final audit report.

Group-IB SOC Consulting addresses this by assessing security operations using the SOC-CMM capability and maturity model and comparing detection coverage to the MITRE ATT&CK Framework for Enterprise. 

A gap assessment of security controls and a review of SOC documentation help pinpoint areas where logging and escalation might not meet auditor expectations or align with local regulations. The results are summarized in a prioritized report that includes an improvement roadmap, giving security leaders a clear, budget-friendly plan to implement before the audit begins.

In 2024, Group-IB became the first SOC-CMM Network Silver Support Partner in Asia, providing these assessments through its Digital Crime Resistance Centers across Europe, the Middle East, Central Asia, and Asia-Pacific. This collaboration strengthens the operational controls auditors will review, but it doesn’t replace the attestation itself, which remains the responsibility of a licensed CPA firm.
