TL;DR: SOX 404(b) preparation hinges on documenting, testing, and evidencing internal controls, and Zluri’s article shows why access review, segregation of duties, and remediation workflows sit at the centre of audit readiness. For identity teams, the compliance problem is not the audit itself but whether access governance is provable enough to withstand external scrutiny.

Questions worth separating out
Q: How should security teams prepare access governance for SOX 404(b) audits?
A: They should scope access controls to financial reporting risk, then prove those controls with review evidence, ownership records, and remediation closure.
Q: Why do access reviews fail SOX 404(b) scrutiny even when they are completed?
A: They fail when the programme cannot show what was reviewed, who approved it, why exceptions were accepted, and how issues were closed.
Q: What breaks when segregation of duties is weak in financial systems?
A: When the same identity can initiate, approve, and reconcile transactions, the control assumption behind SOX testing collapses.
Practitioner guidance
- Map identities to reporting-critical processes Start with journal entries, approvals, reconciliations, and financial reporting pipelines.
- Build defensible access evidence packs For every review cycle, retain the entitlement list, reviewer decision, exception rationale, and remediation closure evidence in one traceable record.
- Prioritise segregation of duties for shared and automated identities Look for service accounts or integration users that can create, approve, or post financial actions in the same flow.

SOX 404(b) access review gaps: what IAM teams need to fix?

SOX 404(b) is really an identity assurance problem disguised as a finance control problem. The article correctly centres control testing, documentation, and review evidence, but those outcomes depend on whether access governance can withstand external inspection. That matters for human access, privileged access, and machine accounts feeding financial systems. The practitioner conclusion is that audit readiness starts with provable entitlement control, not with the auditor.
A few things that frame the scale:
- 72% of organisations have experienced or suspect they have experienced a breach of non-human identities, according to 2024 ESG Report: Managing Non-Human Identities.
- 46% of organisations have confirmed a non-human identity breach, which shows how often machine access issues become real incidents rather than theoretical exposure.
A question worth separating out:
Q: Who should own remediation when SOX control exceptions are found?
A: The control owner should own remediation, not the auditor or the access review team. That owner needs to close the loop with documented fixes, compensating controls, or approved risk acceptance. Without accountable closure, the same exception becomes a recurring audit finding.
