This is the question we get asked most often, usually by a founder who just got a security questionnaire from a prospect and needs an answer within the hour. Here's the short version, then the detail that actually matters for your timeline.
The core difference
Type 1 answers the question: "Are your security controls designed correctly, as of today?" It's a snapshot audit. The auditor reviews your policies and control design at a single point in time.
Type 2 answers the question: "Have your security controls actually been operating correctly over a period of time?" The auditor observes evidence — access logs, ticket records, review sign-offs — across an observation window, typically 3 to 12 months, most commonly 6.
Why this distinction exists
A company can write a beautiful access control policy and still let ex-employees keep their logins for months. Type 1 wouldn't catch that — the policy exists, so the control is "designed" correctly. Type 2 would catch it, because it checks whether the policy was actually followed over time. That's why enterprise security teams increasingly ask for Type 2 specifically; Type 1 tells you intentions, Type 2 tells you behavior.
| Type 1 | Type 2 | |
|---|---|---|
| What's assessed | Control design at one point in time | Control operation over a period |
| Observation window | None — single date | 3-12 months (6 is typical) |
| Time to report | 4-8 weeks after readiness | Readiness period + full observation window + audit |
| Enterprise acceptance | Often accepted as interim proof | Generally the expected standard |
| Typical use case | First-time report, urgent deal in progress | Renewal, or first report when timeline allows |
Which one do you actually need?
If you have zero SOC 2 history and a prospect needs something in the next 60 days, a Type 1 report is often the realistic option — it can demonstrate your controls are in place while your Type 2 observation period runs in parallel. Many companies do a Type 1 in year one specifically to unblock deals, then move to Type 2 in year two once they have enough operating history.
If you're not under immediate deal pressure and have 6+ months of runway before you need a report, skip Type 1 entirely and go straight for Type 2 — it's the stronger signal and you'll need it eventually anyway.
What the observation window actually requires
During the Type 2 window, you're not just "waiting it out" — your team needs to actually execute the controls consistently: access reviews on schedule, incident response drills documented, vendor risk assessments completed, security training tracked. The auditor will sample evidence from across the whole window, so gaps in month 3 show up just as clearly as gaps in month 1.
Bottom line
- Need something fast for an active deal → Type 1 now, Type 2 in parallel
- Have 6+ months of runway → go straight to Type 2
- Already have Type 1 → your next report should be Type 2, not another Type 1
