SOC 2 Type 1 vs Type 2: Differences, Cost and Timelines

Use this to orient quickly before the detail below.

Most organisations treat Type 1 as a milestone on the way to Type 2. That's the right mental model to hold going in.

A SOC 2 Type 1 report is a point-in-time assessment. An independent auditor reviews your security controls on a specific date and confirms whether they're suitably designed to meet the AICPA's Trust Services Criteria (the American Institute of Certified Public Accountants). The key word is "designed": Type 1 checks whether controls exist and are structured appropriately as of that date.

It covers whether your controls are documented and in place, whether their design aligns with the Trust Services Criteria you've selected (Security is mandatory; Availability, Confidentiality, Processing Integrity and Privacy are optional), and a management assertion plus auditor opinion, both dated to the report date.

Type 1 is the faster path to having something in hand. For organisations that recently implemented controls and need to demonstrate security credibility without waiting out a six-to-twelve month observation period, it provides real assurance quickly. It's also a useful internal exercise: going through a Type 1 audit forces you to document controls properly, find gaps, and build the evidence habits Type 2 will demand. Enterprise procurement teams increasingly expect Type 2, though, so if your target market is mid-market or enterprise, treat Type 1 as a checkpoint rather than the finish line.

A SOC 2 Type 2 report goes further. The auditor tests whether those controls operated effectively over a defined review period, usually six to twelve months, going beyond simply confirming they're designed correctly. That's what makes Type 2 the standard enterprise buyers actually trust: it's evidence of sustained practice over time.

The auditor tests whether controls were consistently applied throughout the observation period, whether exceptions occurred and how they were handled, and whether the control environment held up under real operating conditions. A Type 1 report tells a buyer your controls looked right on a Tuesday in March. A Type 2 report tells them your controls ran correctly for the past year, and for enterprise procurement, vendor risk teams and regulated industries, that difference decides whether a deal proceeds or stalls.

If you're selling into financial services, healthcare, or any customer with a formal vendor risk programme, Type 2 is usually a prerequisite rather than a nice-to-have, one piece of the wider audit our SOC 2 compliance checklist walks through end to end.

Type 2 audits cost more because the auditor tests controls across the whole observation period, reviews more evidence and documents any exceptions in far more detail than a Type 1 engagement requires. US pricing from CPA firm Pun Group puts Type 1 fees at $5,000 to $20,000 and Type 2 at $20,000 to $50,000 for small-to-mid-market engagements; UK-focused figures, broken down by company stage, sit in our full SOC 2 certification cost breakdown.

Timeline is usually the deciding factor for organisations under pressure from a specific customer or deal. Type 1 fieldwork itself usually takes four to eight weeks once you're ready, but the real caveat is readiness work: if controls aren't documented, policies aren't in place, or evidence collection is inconsistent, expect two to four months from kickoff to report in hand.

Type 2 runs in two phases. The observation period is the stretch over which controls must operate before the auditor can test them; most auditors will accept as little as three months for a first report, with twelve months becoming standard once you're renewing annually. The audit itself, once the observation period ends, usually runs four to eight weeks. Total time from starting readiness work to receiving a Type 2 report usually lands at six to fifteen months, depending on the length of observation period you choose.

That's why organisations under time pressure often start with Type 1, then move to Type 2 once the observation period has accumulated. You can begin the Type 2 observation period immediately after Type 1 completes, and the work carries forward.

For most early-stage companies, Type 1 is the right starting point. Controls that have just gone live haven't been running long enough to support a Type 2 observation period, a prospect or investor is usually asking for something now, and Type 1 validates control design before committing to a full Type 2 programme.

SMBs, early-stage customers and prospects who mainly want evidence that you take security seriously will usually accept a Type 1 report. Enterprise customers, regulated industries and any customer running a formal vendor risk process will usually require Type 2. But if the sales pipeline is trending toward larger deals, plan for Type 2 from the outset even while Type 1 unblocks the near-term work.

Yes, and it's the most common progression. Type 1 and Type 2 are sequential stages of the same programme. Once the Type 1 report is complete, the Type 2 observation period can begin immediately, and the auditor tests whether controls operated effectively from that point forward, with no need to rebuild the control framework.

Evidence continuity is the part that actually determines success. Access reviews need to happen on schedule throughout the period, change management logs need to be maintained continuously, security incidents need to be documented as they occur rather than reconstructed at audit time, and vendor assessments and policy reviews need to follow their documented cadence. Organisations that struggle with Type 2 usually built their controls for the Type 1 snapshot, then let evidence collection lapse. When the Type 2 auditor asks for twelve months of access review logs, they're rebuilding from scratch, without the evidence that should already have been there.

The fix is treating evidence collection as a continuous habit from day one. Automating that collection through a platform that maps controls to evidence requirements and tracks owner accountability is what separates the teams that move through Type 2 cleanly from the ones scrambling before the audit window opens. Our guide to automating SOC 2 evidence collection covers the practical steps.

Preparing a first Type 1 or running an ongoing Type 2 programme comes down to the same underlying challenge: keeping controls mapped, evidence collected and owners accountable without it consuming the team. SureCloud Assure maps controls to the SOC 2 Trust Services Criteria from day one, gathers evidence throughout the year as a steady habit, contributing to a 75% reduction in audit prep time, and tracks control ownership within the platform alongside every other record.

For organisations moving from Type 1 to Type 2, that means evidence habits are already running before the Type 1 audit even closes, so the Type 2 observation period starts on a system that already works. Nothing gets built from scratch.
