TL;DR: Toxic combinations in segregation of duties let one user complete incompatible business actions such as creating and approving payments, increasing fraud, error, and compliance risk across ERP, cloud, and finance workflows, according to SecurEnds. The control problem is not merely access volume but role design, exception handling, and review cadence.
Editorial analysis by NHI Mgmt Group, based on content published by SecurEnds: “Entitlement management: What Are Toxic Combinations in SoD?”.
Key questions
Q: What breaks when one person can create and approve the same financial transaction?
A: The control stops detecting fraud and errors because the same identity can introduce, authorise, and conceal an entry.
Q: Should organisations prioritise remediation over mitigation for SoD conflicts?
A: Yes, remediation should come first whenever access can be removed without disrupting essential operations.
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 SoD at the business-process layer Map incompatible steps such as create, approve, post, and pay before translating them into entitlement rules.
- Track access drift as a lifecycle problem Review emergency access, mergers, job changes, and manual provisioning together so obsolete permissions do not persist as hidden SoD violations.
- Automate continuous conflict detection Run entitlement analysis against SoD rules continuously across ERP, finance, and cloud applications instead of waiting for periodic review cycles.
Bottom line: Toxic segregation of duties conflicts show that access governance can fail even when individual permissions look valid on their own.

SoD conflicts are a process-governance failure, not an access-volume problem. The article shows that a user can hold individually legitimate entitlements and still violate control intent when those permissions combine inside one workflow. That is why entitlement count alone is a poor signal for governance maturity. The real question is whether the role model preserves independent review across business steps.
A question worth separating out:
Q: What is the difference between segregation of duties and toxic combinations?
A: Segregation of duties is the control principle that separates incompatible responsibilities. Toxic combinations are the actual access states that violate that principle, such as a user who can both create and approve the same financial action. One is the design rule, the other is the control failure.
