Understanding the options

Type I or
Type II?

Two distinct SOC 2 reports. Two different signals to enterprise buyers. Understanding the difference — and choosing the right one for your situation — is the most important decision before you begin.

When to choose each

Making the right choice

TYPE I

Choose Type I when…

You need to unblock a specific sales deal on a short timeline. You have no prior compliance certifications. You’re in early stages and want to validate control design before committing to the longer observation period. You plan to upgrade to Type II within 12 months.

TYPE II

Choose Type II when…

You’re selling to enterprise, financial services, healthcare, or government clients. Your procurement questionnaires explicitly require Type II. You want a report that will be trusted globally without follow-up questions. You’re building a long-term compliance program.

TYPE I → II

The Type I bridge strategy

Many clients start with Type I to unblock immediate revenue, then immediately begin the Type II observation period. This means you have a valid report for current deals while building toward the market-standard attestation simultaneously. Ariol supports both phases under a single engagement.

Buyer / Segment	Type I Accepted	Type II Required	Notes
SMB / Mid-market SaaS	✓ Usually accepted	Not always required	Type I often sufficient to close deals at this tier
Enterprise (Fortune 500)	Rarely sufficient	✓ Almost always required	Enterprise security teams typically require minimum 6-month observation period
Financial Services	Not accepted	✓ Required	Banks and insurance firms require Type II minimum; some require annual renewal evidence
Healthcare / HIPAA-adjacent	Rarely accepted	✓ Required	Often paired with HIPAA BAA; SOC 2 Type II demonstrates security controls baseline
Government / Public Sector	Not accepted	✓ Required	FedRAMP Moderate requires SOC 2 Type II as a foundational element
Venture-backed / Series A–B	✓ Acceptable initially	✓ Expected by Series C	Investors and board members increasingly require Type II as part of security due diligence

Questions

Type I & II FAQs

Can we go straight to Type II without doing Type I first?

Absolutely. Type I is not a prerequisite for Type II. If your timeline allows for the observation period (typically 6 months), going directly to Type II is often the more efficient path — it avoids paying for two separate engagements.

How long must the Type II observation period be?

AICPA guidelines require a minimum of 6 months for a Type II observation period. In practice, most CPA firms and enterprise buyers expect 6–12 months. The observation period begins once your controls are implemented and operational.

Is SOC 2 a certification or an attestation?

Technically, SOC 2 is an attestation — not a certification. A licensed CPA firm evaluates your controls and issues a report. There is no central body that «grants» a SOC 2 certification. The term «SOC 2 certified» is commonly used in industry, but the correct terminology is «SOC 2 attested» or «SOC 2 report issued.»

What happens if exceptions are found during the audit?

If a CPA auditor identifies exceptions (control failures), they are documented in the report. Exceptions do not automatically mean the audit «fails» — the auditor issues an opinion on the overall effectiveness of controls. Our mock audit in Phase 04 is specifically designed to surface and remediate exceptions before the formal audit.
