SOC 2 Audit Process, Timeline, & Costs

SOC 2 Type 1 vs Type 2

Definitions and Key Differences

SOC 2 Type 1
Auditors evaluate whether the controls relevant to security, availability, processing integrity, confidentiality, and/or privacy are properly designed and exist as of a specific date. This assessment provides a fixed-point view of your control environment.
SOC 2 Type 2
Auditors evaluate whether the controls are not only suitably designed but also operating effectively throughout the review period. The review period is at least three months and often extends to six or twelve months to satisfy enterprise and regulatory requirements.

Typical Scenarios for Each

Type 1
Suits organizations starting SOC 2 compliance or seeking quick assurance to accelerate sales or secure investor confidence.
Type 2
Meets the expectations of enterprise clients, procurement teams, and regulated industries that require evidence of consistent control performance.

Observation Period

Type 1 measures control readiness at a single point in time.
Type 2 evaluates operational performance over a continuous monitoring window, usually three to twelve months.

Time and Cost Considerations

Type 1 engagements close in weeks, require less evidence, and reduce audit costs.
Type 2 engagements take longer due to the review period and requires more extensive evidence, increasing both cost and resource requirements.

Trust Signal

Type 1 proves that you have implemented the right controls.
Type 2 proves that you operate those controls consistently, delivering stronger assurance to high-security and compliance-driven clients.

TrustNet’s Recommendation

If you’re new to SOC 2, begin with a Type 1 to establish market credibility quickly. As your compliance program matures and client requirements grow, advance to Type 2 to demonstrate ongoing operational integrity and strengthen competitive advantage.

The SOC 2 Audit Process: Step-by-Step

Step 1: Choose Your Report Type

Decide between a SOC 2 Type 1 or Type 2 report.

Type 1 assesses the design of controls at a specific point in time.
Type 2 evaluates the design and operating effectiveness of controls over a defined period.

Step 2: Define the Audit Scope

Identify the systems, processes, and locations to include.
Select the relevant Trust Services Criteria: Security (required for all SOC 2 reports), Availability, Confidentiality, Processing Integrity, and Privacy.
Confirm the timeline and audit objectives.

Step 3: Conduct a Gap Analysis

Compare existing controls against SOC 2 requirements.
Identify areas that fall short of meeting the criteria.
Use these findings to shape your remediation plan.

Step 4: Complete a Readiness Assessment

Review policies, procedures, and controls in detail.
Validate that all documented processes align with the selected Trust Services Criteria.
Assess whether your environment is fully prepared for a formal audit.

Step 5: Design and Implement Controls

Create or improve controls to address any identified gaps.
Deploy technical, administrative, and physical safeguards where required.
Ensure documentation is accurate and accessible.

Step 6: Undergo the Audit

Engage an independent auditor to evaluate your control environment. TrustNet, as an AICPA-accredited firm, can perform the audit directly.
Provide all required documentation, evidence, and system access for testing.
The auditor tests the design of controls for both Type 1 and Type 2. For Type 2, the auditor also verifies operating effectiveness over the defined review period.

Step 7: Review the Audit Report

Examine the auditor’s findings and confirm accuracy.
Address any exceptions by updating processes or controls.
Use the report to demonstrate compliance to clients and stakeholders.

Step 8: Achieve Attestation

A successful audit results in a SOC 2 report that validates your security and compliance posture.
Ensure continuous monitoring to maintain the controls and processes that earned attestation to prepare for future audits.

How Long Does a SOC 2 Audit Take?

The following timelines are industry-based estimates. Your actual SOC 2 audit duration will depend on factors such as control maturity, existing documentation, team availability, and the complexity of your environment.

Preparation (Pre-Audit / Gap Assessment)

The readiness phase ranges from 2 weeks to 9 months.
Organizations with mature controls and prior compliance experience can complete this in a few weeks.
Building or enhancing controls from scratch may take several months.

Type 2 Observation Window (Type 2 Only)

The observation period typically spans 3 to 12 months.
Shorter periods (3–6 months) suit initial audits, while established programs often use a 12-month window to meet client expectations.

Audit Fieldwork & Report Writing

Plan for 1 to 3 months to complete evidence review, interviews, system walkthroughs, field testing, draft reporting, and final report issuance.
For both Type 1 and Type 2, fieldwork typically takes 3–6 weeks, and final report review adds 2–3 weeks.

Phase	Type 1 Duration	Type 2 Duration
Preparation/Gap	2 weeks - 6 months	2 weeks - 6 months
Observation Window	N/A	3, 6, 9, or 12 months
Audit Fieldwork	2 - 6 weeks	2 - 6 weeks
Report Finalization	2 - 6 weeks	2 - 6 weeks
Typical Total Time	4 - 8 weeks	5–15 months, depending on window

How Much Does a SOC 2 Audit Cost?

Note: These numbers serve as industry benchmarks. Your actual costs will depend on factors like audit maturity, scope, readiness level, internal resources, and auditor choice.

Cost Drivers

Audit type: Type 1 or Type 2
Number of Trust Services Criteria included (Security required)
Organizational size and operational complexity
Scope: cloud vs. on‑prem, multiple locations
Remediation efforts and readiness maturity
Choice of auditor and their rates
Additional costs: readiness support, remediation work, evidence automation tools

Typical Ranges

SOC 2 Type 1: $10,000–$25,000 for most organizations; large enterprises may reach $50,000–$60,000.
SOC 2 Type 2: $20,000–$60,000 is common; complex or large-scale audits can exceed $100,000.

SOC 2 Audit Frequency

Best Practices

Conduct annual Type 2 audits to meet procurement expectations and maintain a current compliance posture.
Recognize that SOC 2 reports are generally valid for 12 months; after this, customers may consider them outdated.
Use continuous compliance cycles, such as starting with a shorter observation window for the first Type 2 audit, then moving to recurring annual audits.
Consider six-month Type 2 audits if you want more frequent assurance and closer control validation.
Schedule audits strategically, align them with contract renewals, sales cycles, or fiscal planning to avoid report gaps.
If significant operational changes occur, such as infrastructure updates, new policies, or acquisitions, conduct a mid-cycle assessment or short-window audit to maintain assurance.

TrustNet’s Guidance

Build continuous compliance with automated evidence collection and quarterly control reviews to keep each audit cycle smooth and low risk.
Maintain complete control documentation and up-to-date evidence year-round to respond quickly to customer or procurement requests.
Treat each audit as a chance to improve your control environment and strengthen operational resilience, not just as a compliance exercise.
