How Long Does SOC 2 Take? A Realistic Timeline for Startups

SOC 2 is an attestation framework defined by the AICPA. Unlike ISO 27001, which is a certification, SOC 2 produces a report issued by a licensed CPA firm. Every SOC 2 engagement is scoped to one or more of five Trust Services Criteria: Security (required), plus optionally Availability, Processing Integrity, Confidentiality, and Privacy.

The timeline hinges almost entirely on whether you pursue a Type 1 or Type 2 report. Understanding that split is the whole page—it is also the thing readers searching this question most often do not know when they land. For a deeper dive on the differences, see our SOC 2 Type 1 vs Type 2 comparison.

Here is how the timeline breaks down for each report type, from standing start to signed report:

Type 1 total: 2 to 3 months. The fastest teams with strong existing controls can complete a Type 1 in six to eight weeks. Type 2 total: 6 to 12 months. The observation window is the floor—three months minimum, six months typical, twelve months for first-time audits at firms that prefer a full-year window.

The readiness phase is where you learn what you are missing. A structured gap analysis maps your current state against the SOC 2 Trust Services Criteria and identifies every control, policy, and evidence artifact you need before the auditor arrives.

For most early-stage startups, the gap analysis surfaces the same categories of missing work:

• Missing or informal policies. SOC 2 requires documented policies for information security, access control, change management, incident response, and risk assessment. Most startups have fragments in a wiki but nothing that satisfies an auditor.
• No change management process. The Common Criteria require documented, reviewable change management. Code reviewed in pull requests usually counts, but only if the process is documented and consistently followed.
• Incomplete access reviews. Quarterly access reviews are a near-universal SOC 2 control. Most startups have never run one. The review itself takes an afternoon; the gap is that the process does not exist yet.
• No vendor due diligence. Third-party risk management is part of the Common Criteria. Subprocessors, cloud providers, and SaaS tools all need documented review.

A thorough readiness assessment takes two to four weeks. Rushing it creates blind spots that surface during fieldwork as exceptions—adding weeks and eroding confidence in the report.

Remediation is where the bulk of the hands-on work happens. You are building and documenting the controls the auditor will test. For most startups, this involves:

The observation window is the phase that makes Type 2 take longer than Type 1—and it is the one phase you cannot accelerate by working harder. During this period, your controls must operate continuously and generate evidence. The auditor will later sample from this evidence to confirm the controls worked as designed throughout the period.

Common observation window lengths:

During the window your job is straightforward: run every control on schedule, collect the evidence, and fix any control failures before the auditor samples them. A control that fails during the window and is not remediated becomes an exception in the report—the one thing buyers read first.

Fieldwork is the auditor’s hands-on testing phase. For Type 1, the auditor examines your controls at a point in time. For Type 2, they sample evidence from across the observation window.

Several factors can meaningfully compress the readiness-and-remediation phases (though not the observation window):

• Existing ISO 27001 certification. If you already hold ISO 27001, you have most of the policy suite, risk assessment process, and operational controls SOC 2 requires. The gap narrows to AICPA-specific criteria and evidence formatting.
• A dedicated compliance owner. Assigning one person—even part-time—to drive the SOC 2 project is the single biggest timeline accelerator. Diffuse ownership means nothing ships.
• Automation tooling. Tools that auto-collect evidence (access logs, change records, vulnerability scans) eliminate the manual screenshot collection that typically consumes weeks of engineer time before fieldwork.
• Engineering-native change management. If your team already does code review in pull requests, you have a head start on one of the most evidence-heavy controls. Document the process and you are done.
• Starting with Type 1. A Type 1 proves your controls are designed correctly while you begin the observation window for Type 2. Some buyers accept a Type 1 as a bridge while you work toward the Type 2.

Timelines vary by company stage. Here is a realistic breakdown assuming a Type 2 engagement with a six-month observation window:

The biggest time sinks in SOC 2—writing policies, collecting evidence, running access reviews, maintaining a control register—are where Vylint Shield has the most impact.

• Pre-built SOC 2 policy library. Start with auditor-reviewed policy templates mapped to the Trust Services Criteria. Customize in minutes, not weeks.
• Guided readiness assessment. A short assessment surfaces the gaps between where you are and where you need to be—before you engage an auditor.
• Automated evidence collection. Connect your cloud providers and identity tools. Evidence pulls automatically so nothing is missing when the observation window closes.
• 61 SOC 2 controls mapped and tracked. Every control has a description, owner assignment, and evidence requirement. Your auditor walks through them in minutes, not days.

Teams using Vylint Shield consistently complete SOC 2 readiness in four to six weeks—cutting the remediation phase in half. Compare the ISO 27001 timeline to see how the two frameworks compare, or learn what to expect in your first 30 days of SOC 2.

Timeline and cost are two sides of the same question. Auditor fees, tooling costs, and internal time all scale with scope and duration. For a full breakdown of what SOC 2 costs at each stage, see our SOC 2 cost guide.
