Is SOC 2 or ISO 27001 better?

Neither is universally better. SOC 2 is usually the faster, cheaper choice for U.S. SaaS companies whose customers ask for it. ISO 27001 is an internationally recognized certification often preferred for global or enterprise deals. Many companies eventually do both.

How long does SOC 2 take?

A SOC 2 Type I report can take 6-12 weeks of preparation. A Type II report additionally requires an observation window (typically 3-12 months) during which controls are monitored.

How much does ISO 27001 cost?

Total cost varies with company size, but typically ranges from roughly $15k-$50k+ including consulting, tooling, and the certification audit. SOC 2 is often comparable or slightly lower for a first report.

Can one project cover both SOC 2 and ISO 27001?

Yes. The two frameworks share many controls, so a well-run program can map evidence once and satisfy both - which is far cheaper than tackling them separately.

SOC 2 vs ISO 27001: Which Does Your Business Need?

If your customers or investors have started asking whether you’re “SOC 2 compliant” or “ISO 27001 certified,” you’re not alone - and choosing between them is one of the most common questions we hear from growing companies. This guide breaks down the difference in plain English so you can pick the right path and stop losing deals to security questionnaires.

What is SOC 2?

SOC 2 is an attestation report produced by an independent CPA firm, based on the AICPA’s Trust Services Criteria (security, availability, processing integrity, confidentiality, and privacy). It’s the de facto standard U.S. SaaS and technology companies are asked for. There are two flavors: Type I (controls designed correctly at a point in time) and Type II (controls operating effectively over a period, usually 3-12 months).

What is ISO 27001?

ISO 27001 is an internationally recognized certification for an Information Security Management System (ISMS). Rather than a report, you earn a certificate from an accredited body after an audit. It’s widely respected globally and is often the expectation for enterprise and international deals.

SOC 2 vs ISO 27001: the key differences

Format: SOC 2 is an attestation report; ISO 27001 is a formal certification.
Geography: SOC 2 dominates in the U.S.; ISO 27001 is the global standard.
Scope: ISO 27001 emphasizes a management system and continuous risk process; SOC 2 focuses on control criteria.
Audience: SOC 2 reports are shared under NDA with prospects; an ISO 27001 certificate is public and easy to display.
Renewal: SOC 2 Type II is typically annual; ISO 27001 runs on a three-year cycle with surveillance audits.

Which should you choose?

Choose SOC 2 if you’re a U.S. SaaS company and your customers are specifically asking for it - it’s usually the fastest way to unblock sales. Choose ISO 27001 if you sell internationally, into large enterprises, or want a globally portable certificate. If both keep coming up in deals, do them together: the control overlap means one well-run program can satisfy both at a fraction of the combined cost.
