SaaS firms often need ISO 27001 for global deals and SOC 2 for US enterprise sales. Running two programs means writing policies twice and pulling evidence twice. You can avoid that with one program that meets both. Many teams start with ISO 27001 consulting services to set scope and risk correctly.
Why Companies Pursue Both At Once
ISO 27001 is an international standard for an Information Security Management System. You define context, assess risks, select Annex A controls, and show improvement through internal audit and management review. Certification comes from an accredited body on a three year cycle.
SOC 2 is an attestation, not a certification. A CPA firm tests controls against Trust Services Criteria: Security, Availability, Processing Integrity, Confidentiality, Privacy. Type 1 checks design at a point in time. Type 2 checks operation over three to twelve months.
ISO 27001 shows you run a governed risk based program. SOC 2 shows controls operated for customer data over time.
What Makes ISO 27001 And SOC 2 Different
Scope And Outcome
ISO 27001 scope is your ISMS: people, locations, systems, assets. The outcome is a certificate. SOC 2 scope is a system and chosen criteria. Outcome is a report with opinion and test results.
Control Structure
ISO 27001:2022 has clauses 4 to 10 and 93 Annex A controls across organizational, people, physical, technological themes. SOC 2 uses CC1 to CC8 for environment, communication, risk assessment, monitoring, access, operations, change, mitigation, plus extra criteria for availability and confidentiality.
Where The Overlap Lets You Save Work
Overlap is 65 to 75 percent for core security work. One policy and one evidence set can satisfy both if you map early. Shared areas include access management, risk assessment, asset inventory, encryption, logging, vulnerability management, incident response, continuity, supplier security, and training.
How To Build One Program For Both
Step 1 Start With Unified Risk Assessment And Scope
Define one ISMS scope that also matches SOC 2 boundary. Run one risk assessment for confidentiality, integrity, availability. Document treatment once. This feeds ISO Clause 6 and SOC 2 CC3.
Step 2 Map Controls Once
Create one matrix with control, owner, frequency, links to Annex A and Trust Services Criteria. Example: quarterly access review maps to A.5.18 and CC6.1. Keep Statement of Applicability as source of truth and add SOC 2 column.
Step 3 Create Shared Evidence
Organize evidence by control, not framework. Keep policy, ticket, screenshot, log in one folder with date and owner. Scan report supports A.8.8 and CC7.1.
If you are setting up files for the first time, see our ISO 9001 Compliance Checklist: 15 Documents and Records You Must Have for Audit for a practical view of how auditors expect files to be organized.
Step 4 Run One Internal Audit And Management Review
ISO 27001 requires internal audit and management review. SOC 2 benefits because they show monitoring under CC1 and CC4. Use the same plan and minutes for both.
When To Bring In Iso 27001 Consulting Services
Scoping errors cause most rework. Teams scope too narrow and expand later, or too wide and add extra work. A partner experienced in gap analysis, documentation, implementation, and audit support can define defensible scope and align ISO Stage 1 and Stage 2 with SOC 2 observation window.
What To Expect For Timeline And Cost
Firms with basic controls need six to twelve months for ISO 27001 and three to nine months for SOC 2 Type 2 readiness. SOC 2 Type 2 fees often range from 15k to 75k. Savings come from one risk assessment and shared pulls.
Bringing It All Together
You do not need two security programs to earn two trust signals. Build one ISMS, map each control to Annex A and Trust Services Criteria, and collect evidence once with clear ownership. Align audit windows so same period supports both.

FAQs
Can You Get ISO 27001 And SOC 2 At The Same Time?
Yes. Use one risk assessment and one control set, map to both, and schedule ISO Stage 2 and SOC 2 Type 2 to share the same evidence window.
Which Should Come First, ISO 27001 Or SOC 2?
If US buyers ask for SOC 2 now, start with SOC 2 and design controls to also meet Annex A. If international buyers ask for ISO, start with ISO and add SOC 2 mapping.
How Much Overlap Is There Between ISO 27001 And SOC 2?
About 65 to 75 percent for core areas like access control, risk management, monitoring, incident response. You still need Statement of Applicability for ISO and system description for SOC 2.
Do I Need Different Auditors For Each?
Yes. ISO 27001 requires an accredited certification body. SOC 2 requires a licensed CPA firm. You use the same evidence, but external auditors are different.
What Is The Biggest Time Saver For Dual Compliance?
One folder per control with owner, frequency, date. When each control has one procedure and one folder that links to both, you cut interviews.
