The Core Difference

SOC 2 is an audit report. A licensed CPA firm examines your controls and issues an attestation. Your customers receive a report — typically 50–200 pages — documenting what was tested and what the auditor found.

ISO 27001 is a certification. An accredited certification body audits your Information Security Management System (ISMS) against the ISO standard and issues a certificate. Your customers receive a certificate number they can verify.

Both address information security. But they originate from different regulatory ecosystems, carry weight in different markets, and require different organizational investments.

Who Requires SOC 2

SOC 2 is primarily a US market requirement, originating from the AICPA framework. You need it when:

• Your customers are US-based enterprises with formal vendor risk programs
• Your prospects are in regulated US industries: financial services (SOX compliance chains), healthcare (HIPAA chains), government contractors (FedRAMP adjacent)
• Your enterprise deals stall at the "we need a security attestation" stage
• Your average contract value exceeds $30,000 and your buyers have procurement gatekeepers

If you sell B2B SaaS to US companies and have enterprise ambitions, SOC 2 Type II is not optional — it's the standard the US market has converged on.

Who Requires ISO 27001

ISO 27001 is primarily a European and international market requirement. You need it when:

• Your customers are European enterprises, particularly in the UK, Germany, Netherlands, or Nordics
• You're selling into government or public sector outside the US
• Your prospects operate in industries where ISO 27001 is contractually mandated
• You want a globally portable certification that the European market recognizes

Many European enterprises accept SOC 2 as a proxy for ISO 27001, and vice versa — but not universally. If your growth is European, ISO 27001 is the path of least resistance.

Timeline and Cost

|---|---|---| ISO 27001 doesn't have an observation period like SOC 2 Type II. However, it requires building a full ISMS — documented policies, risk register, supplier assessments, internal audits — which is a significant organizational investment beyond just technical controls.

Technical Controls Overlap

Both frameworks require essentially the same technical controls. If your AWS infrastructure passes SOC 2, most of those same controls satisfy ISO 27001 Annex A requirements:

• Access control and MFA → ISO 27001 A.9
• Encryption → ISO 27001 A.10
• Logging and monitoring → ISO 27001 A.12
• Change management → ISO 27001 A.12.1
• Incident response → ISO 27001 A.16
• Supplier/vendor risk → ISO 27001 A.15

The difference is in the organizational and governance layer. ISO 27001 requires a formal risk assessment methodology, Statement of Applicability, internal audit program, and management review process. These exist in SOC 2 as well, but ISO 27001 is more prescriptive about how they must be documented and managed.

Choosing Where to Start

Start with SOC 2 if:

• Your primary market is the United States
• Your deals are being blocked by US enterprise security reviews now
• You're AWS/GitHub-native and want technical automation to carry the load

Start with ISO 27001 if:

• Your primary market is Europe
• Your deals are being blocked by European procurement requirements
• Your customers specifically ask for ISO 27001 certification

Do both if:

• You're selling globally across US and European enterprise
• Your Series B+ scale warrants the investment
• Specific regulated industries require it contractually

The practical path for most US SaaS startups: Get SOC 2 Type II first. Use the technical control work as a foundation. Add ISO 27001 when European deals start demanding it. The ISMS documentation required for ISO 27001 builds on the policy and control foundation you created for SOC 2.

SecureSpect's control checks align to both SOC 2 Trust Service Criteria and ISO 27001 Annex A — the same automated evidence works for both audit processes.
