TL;DR: ISAE 3402 focuses on controls tied to financial reporting, while SOC 2 covers security, availability, processing integrity, confidentiality, and privacy for service organisations, according to Zluri. The distinction matters because identity governance must map assurance requirements to the actual access risks, review cadence, and evidence burden across human, NHI, and service-provider accounts.
Editorial analysis by NHI Mgmt Group, based on content published by Zluri: “ISAE 3402 Vs SOC 2: What’s Best For Your Business?”.
Key questions
Q: How should security teams decide between ISAE 3402 and SOC 2?
A: Choose ISAE 3402 when the main assurance question is whether service controls affect financial reporting.
Q: Why do identity controls matter in a SOC 2 audit?
A: Identity controls show who can access systems, how privilege is approved, and whether access is removed when it is no longer needed.
Q: What breaks when service access is governed under the wrong assurance standard?
A: The problem is usually evidence mismatch.
Practitioner guidance
- Map the assurance objective to the control boundary Decide first whether the service is being evaluated for financial reporting integrity or broader trust services such as security and privacy.
- Separate finance-facing and security-facing access evidence Keep a distinct evidence set for controls that support financial reporting and another for controls that support confidentiality, availability, and privacy.
- Document control objectives before documenting controls Write the control objective in plain language, then show which identity controls, reviewers, and artefacts prove it.
Bottom line: ISAE 3402 and SOC 2 are not interchangeable, because they answer different assurance questions about service organisations.

Assurance scope, not audit branding, is the core identity decision. The article shows that ISAE 3402 and SOC 2 answer different control questions, so identity teams should not treat them as interchangeable attestations. When access governance is built for the wrong assurance boundary, reviews and evidence can miss the actual risk that matters to the business. Practitioners should align the standard to the control objective before choosing the review model.
A question worth separating out:
Q: What is the difference between Type I and Type II assurance reports?
A: Type I reports assess whether controls are suitably designed and implemented at a point in time. Type II reports go further by testing whether those controls operated effectively over a period. Identity teams should expect Type II to require more durable evidence, especially for access reviews and monitoring.
