SOC 2 vs ISO 27001: Which Framework Wins You the Deal?
SOC 2 is the de facto US enterprise expectation. ISO 27001 is the international certification. The right choice depends on where your customers are — not on which is "better."

When SOC 2 vs ISO 27001 comes up
US-first startups choose SOC 2 over ISO 27001 when speed to first enterprise deal matters more than international certification breadth.
ISO 27001 timeline kills startup sales cycles
A 12-18 month path to certification is incompatible with a customer who needs proof of security in 30-60 days. For US-first startups, SOC 2 Type 1 in 6-10 weeks is the realistic answer to "do you have ISO 27001?" — followed by ISO when the EU expansion actually materializes.

Statement of Applicability becomes a moving target
ISO 27001:2022 requires a Statement of Applicability covering 93 Annex A controls. For early-stage teams without a dedicated ISMS owner, scoping and re-scoping the SoA across iterations is where the real cost compounds — and where consulting hours pile up.

Certification body fees on top of consultant fees
Unlike SOC 2 (where you pay one CPA firm), ISO 27001 requires a separate accredited certification body for the Stage 1 + Stage 2 audits. Most startups underestimate this — the consulting engagement gets you ready; the certification body charges separately to actually grant the certificate.

What makes SimpleAudit different
SOC 2 is the answer to "what US enterprises actually ask"
Vendor security questionnaires from [US B2B SaaS](/soc2/b2b-saas) enterprise procurement teams default to "Do you have a SOC 2 Type 2 report?" — not "Are you ISO 27001 certified?" If your customers are in the US, SOC 2 is the credential that unblocks deals fastest.
Faster path to first credential
SimpleAudit gets you to a SOC 2 Type 1 report in 6-10 weeks; Type 2 in 3-6 months. That fits a startup sales cycle. ISO 27001's 12-18 month path to certification fits a multi-national enterprise security calendar.
Built for one framework, deeply understood
SimpleAudit is SOC 2-first. The AI knows the Trust Services Criteria, the typical auditor questions, and the evidence patterns that pass first try. A multi-framework platform spreads its expertise across SOC 2, ISO, HIPAA, PCI — depth on any one suffers.
When ISO 27001 is the better choice
ISO 27001 is the right choice if your customer base is primarily in the EU or APAC, if you sell into industries (banking, automotive) where ISO is the procurement default, or if your enterprise prospects have explicitly listed it as a contract requirement. Most US-first SaaS startups can defer ISO until they have a concrete EU expansion deal — typically [Series A or later](/soc2/series-a) — on the line.
Frequently asked questions
Can I do both SOC 2 and ISO 27001?
Yes — and many growing SaaS companies do, in sequence. The typical path is SOC 2 first (faster, US-focused), then ISO 27001 once EU customers start appearing in the pipeline. Roughly 60-70% of the underlying controls overlap, so the second framework is meaningfully cheaper than the first. SimpleAudit covers the SOC 2 side; ISO 27001 currently requires a separate consultant or platform.
Is SOC 2 recognized internationally?
SOC 2 is recognized everywhere but it is not the procurement default outside the US. EU enterprise buyers will often accept a SOC 2 report alongside questions about GDPR alignment and ISO 27001. APAC enterprise buyers in regulated sectors typically require ISO 27001. For a US startup selling to global customers, SOC 2 unblocks the majority of US deals and gets you partial credit on international procurement.
Which auditors can certify both?
No single firm "certifies both" because they are different processes. SOC 2 is an attestation engagement performed by a CPA firm (only CPAs can issue SOC reports). ISO 27001 is a certification granted by an accredited certification body, which is not the same as a CPA firm. Some larger consultancies have separate practices for each and can run them in parallel for you.
How long does each take end-to-end?
SOC 2 Type 1 is realistic in 6-10 weeks from a cold start with a platform like SimpleAudit. Type 2 adds a 3-12 month observation period — so 4-15 months total to first Type 2 report. ISO 27001 typically runs 12-18 months end-to-end (Stage 1 audit, gap remediation, Stage 2 audit, then certification issuance), with a 3-year cycle of annual surveillance audits after.
What does each cost, all-in?
SOC 2 all-in for an early-stage startup: roughly $2,400/year for the SimpleAudit platform plus $20-50K for the audit firm — so $22-52K in year one. ISO 27001 all-in: roughly $30-80K for consultant + accredited certification body fees, spread across the 12-18 month engagement. Both numbers exclude internal team time.
