TL;DR: Separation of duties matrices reduce fraud and unauthorized access by splitting initiating, approving, and processing tasks, and Zluri’s guide frames them as a practical IGA control for access governance, auditability, and compliance. The real issue is that SoD fails when access reviews, approvals, and monitoring stay spreadsheet-driven and disconnected from lifecycle enforcement.
Editorial analysis by NHI Mgmt Group, based on content published by Zluri: “Segregation Of Duties Matrix Template”.
Key questions
Q: What breaks when SoD matrices are only defined in spreadsheets?
A: They break at enforcement.
Q: Why does separation of duties reduce fraud and insider threat risk in cybersecurity?
A: Separation of duties lowers risk because it prevents one individual from completing a critical process without oversight.
Q: How do security teams know if SoD controls are actually working?
A: SoD controls are working only if live access state matches the approved separation model across systems.
Practitioner guidance
- Define conflict pairs explicitly Document which combinations of initiating, approving, processing, and administering access are prohibited for each critical workflow, then make those conflicts visible to app owners and reviewers.
- Bind SoD rules to access certification Use recurring reviews to confirm that conflicting permissions have not accumulated after role changes, exceptions, or project-based access grants.
- Instrument audit trails for decision history Log requests, approvals, rejections, edits, and overrides so the organisation can reconstruct how a SoD decision was made and whether it was honoured in execution.
Bottom line: SoD is still a core IAM control because it prevents one identity from holding conflicting authority over sensitive processes.

SoD matrices are still the clearest operational expression of least privilege in IAM. They translate a governance principle into a control pattern that auditors, security teams, and application owners can all understand. The catch is that the matrix only works when it is enforced through live entitlements, not just process documentation. For practitioners, the real test is whether the control survives contact with actual access administration.
A few things that frame the scale:
- Nearly 60% of IT leaders cite restrictive cost and complexity as a weakness of legacy identity governance, according to the 2025 State of Identity Governance Report.
A question worth separating out:
Q: How should IAM teams enforce SoD across access reviews and lifecycle events?
A: They should treat SoD as a lifecycle control, not just an approval rule. Access changes, role moves, and offboarding should trigger conflict checks so risky combinations are removed before they persist into the next review cycle. That makes the matrix part of routine governance instead of periodic cleanup.
