TL;DR: Splitting employee setup, pay calculation, approval, and reconciliation reduces ghost employees, overpayments, and insider fraud in payroll and HR, according to SecurEnds. The control works only when access, approval, and audit evidence are separated enough to prevent one person from running the full money flow.
NHIMG editorial — based on content published by SecurEnds: segregation of duties in payroll and HR
Questions worth separating out
Q: How should security teams enforce segregation of duties in payroll processing?
A: They should split creation, calculation, approval, and reconciliation across different roles so no single identity can complete the payroll cycle end to end.
Q: Why does role overlap create so much payroll fraud risk?
A: Role overlap lets the same person create a record, approve the output, and hide the mismatch.
Q: What breaks when payroll reconciliation is not independent?
A: Errors and fraudulent entries can survive because the same team that prepared the payroll is also checking its own work.
Practitioner guidance
- Split payroll duties across separate identities Assign employee setup, calculation, approval, and reconciliation to different roles so one person cannot complete the full compensation path alone.
- Move approval outside the processing team Require finance or another independent function to authorise payroll outputs before funds are released, and keep that approval trail distinct from payroll operations.
- Reconcile against source records every cycle Compare approved payroll outputs with HR source data and bank disbursement records, then escalate any mismatch before the next run.

Payroll segregation of duties is an identity governance control, not a finance convenience. The article is really about limiting what a single identity can complete without interruption. That matters because payroll fraud is just one expression of a broader access problem: end-to-end authority hides errors, weakens accountability, and defeats independent review. Practitioners should treat payroll role design as a governance pattern that generalises across human IAM, NHI controls, and any workflow where one identity can finish the transaction alone.
A few things that frame the scale:
- 80% of identity breaches involved compromised non-human identities such as service accounts and API keys, according to Ultimate Guide to NHIs.
- Another finding from the same research shows that 97% of NHIs carry excessive privileges, which is why role overlap so often becomes a breach multiplier rather than a convenience.
A question worth separating out:
Q: Who should own payroll approval in a segregated duties model?
A: Approval should sit outside the payroll processing function, typically with finance or another senior control owner who does not enter or calculate payroll data. That separation preserves accountability and prevents self-approval. It also gives auditors a clear control boundary and makes exception handling easier to review.
