TL;DR: ISO 27001 defines a full information security management system, while SOC 2 audits selected controls through five trust principles, and StrongDM says ISO 27001 typically takes 6 to 12 months and can cost 1.5 to 2 times more than SOC 2. The governance lesson is that certification choice shapes how IAM, PAM, and access evidence are documented, reviewed, and defended across the programme.
NHIMG editorial — based on content published by StrongDM: ISO 27001 vs. SOC 2: Understanding the Difference
By the numbers:
- ISO 27001 certification can take 6-12 months, depending on the size and complexity of your organization.
- ISO 27001 could be anywhere from 1.5 to 2 times more expensive than SOC 2 on average.
- 30% of organizations reported an increase in attacks on their IT systems during the pandemic.
Questions worth separating out
Q: How should teams choose between ISO 27001 and SOC 2 for identity governance?
A: Choose ISO 27001 when you need a full information security management system with broad governance expectations, and choose SOC 2 when you need a scoped attestation over specific controls.
Q: Why do ISO 27001 and SOC 2 create different burdens for IAM teams?
A: ISO 27001 creates a broader burden because it expects policy, operating rhythm, and continual improvement to be documented together.
Q: What do security teams get wrong about treating ISO 27001 and SOC 2 as equivalent?
A: The common mistake is assuming both frameworks ask the same questions.
Practitioner guidance
- Separate ISMS governance from audit attestation Document which controls belong to the broader information security management system and which are only required for the SOC 2 audit scope.
- Map identity evidence to both frameworks Create a single evidence inventory for access approvals, privileged sessions, logs, and offboarding records so the same artefacts can support ISO 27001 and SOC 2.
- Review IAM control boundaries before choosing the audit path Identify whether the organisation needs full-system governance, a narrower control attestation, or both.

ISO 27001 and SOC 2 are governance instruments, not substitutes for identity control design. The article is right to separate the two, but identity teams should not treat either as a proxy for secure access on its own. ISO 27001 forces a broader operating model, while SOC 2 tests a narrower control set. The practitioner conclusion is simple: certification does not fix weak access governance, it only exposes whether the programme can prove itself.
A few things that frame the scale:
- 1 in 4 organisations are already investing in dedicated NHI security capabilities, with an additional 60% planning to do so within the next twelve months, according to The State of Non-Human Identity Security.
- Only 5.7% of organisations have full visibility into their service accounts, which shows how often identity evidence is incomplete before audit work begins.
A question worth separating out:
Q: How can organizations prepare identity evidence for both audits at once?
A: Build one evidence model that covers access approvals, privileged activity, logging, review outcomes, and exception handling. Then map that evidence to the control expectations of each framework. This avoids duplicate collection work and gives auditors a clearer view of how identity governance actually operates.
