When reviews stay manual, teams usually face slower cycles, more errors, weaker audit trails, and higher risk that excessive access will persist unnoticed. The result is a larger attack surface for unauthorized access to financial records, receipts, and travel data. Manual methods also consume staff time that could be spent on higher value governance work.
Why manual Concur access reviews become a control problem
Manual reviews are not just slower, they are harder to make consistent. As reviewer lists, approvals, and evidence are handled by people in spreadsheets or email threads, the process becomes vulnerable to missed exceptions, stale entitlements, and incomplete sign-off records. That matters because Concur often sits on sensitive travel, expense, and reimbursement data, where access should be tightly bounded and traceable.
When reviews are automated, the control can enforce the same review cadence, the same population, and the same evidence format every cycle. That consistency is what turns access review from a periodic administrative task into an auditable governance control. Ultimate Guide to NHIs, Lifecycle Processes for Managing NHIs is useful here because the underlying governance problem is lifecycle discipline: who has access, why they have it, and when it should be removed or recertified.
Manual methods also make it easier for overprovisioned access to linger. In practice, that means former employees, role-changed staff, contractors, or dormant accounts may keep access long after the business need has ended. The control failure is not only inefficiency, it is drift: the access state in the system slowly diverges from the access state the business believes it has.
What breaks operationally when reviews stay manual
Three failure modes show up most often. First, cycle time increases, so access exceptions stay open longer and remediation happens later. Second, the reviewer can miss context, especially when the entitlement list is long or the business owner no longer knows why access was granted. Third, evidence quality drops, because manual approval trails are harder to standardise and easier to challenge during audit.
That combination creates practical control weakness even when the intent is good. A manual review can still be “completed” while the actual risk remains unchanged if nobody acts on exceptions, revokes access promptly, or validates that the reviewer had the authority to approve it. For governance teams, the important question is not whether the review occurred, but whether it produced a timely and defensible access decision.
Research from NHI Management Group’s Ultimate Guide to NHIs, Regulatory and Audit Perspectives shows the scale of the visibility problem in identity governance, with only 5.7% of organisations having full visibility into their service accounts. While Concur is a human-access use case, the governance lesson is the same: if you cannot reliably see who has access, manual review will not keep pace for long.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 address the attack and risk surface, while CIS Controls v8, NIST CSF 2.0, NIST SP 800-63 and NIST Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| CIS Controls v8 | 6 — Access Control Management | Concur reviews govern who retains access and privilege over expense data. |
| Recommendation — Automate access review and revocation for Concur accounts to enforce least privilege. | ||
| NIST CSF 2.0 | PR.AA — Identity Management, Authentication, and Access Control | The question centers on maintaining accurate access decisions over time. |
| GV.RM — Risk Management Strategy | Manual reviews increase governance and audit risk from delayed access decisions. | |
| Recommendation — Use PR.AA processes to recertify Concur access and remove stale entitlements promptly. Set a review cadence and escalation path that reduces residual access risk in Concur. | ||
| NIST SP 800-63 | 4 — Digital Identity Guidelines, Section 4 | Access reviews depend on trustworthy identity assertions and lifecycle decisions. |
| Recommendation — Tie Concur recertification to authoritative identity lifecycle signals and deprovisioning events. | ||
| NIST Zero Trust (SP 800-207) | AC-1 — Policy Enforcement and Least Privilege | Automated reviews support continuous least-privilege enforcement for Concur access. |
| Recommendation — Use policy-driven access decisions to keep Concur privileges aligned to current need. | ||
| OWASP Non-Human Identity Top 10 | NHI-01 — Identity Lifecycle and Offboarding | Although Concur is a human-access use case, the core issue is lifecycle control and access removal. |
| Recommendation — Apply lifecycle discipline so obsolete Concur access is recertified or removed on schedule. | ||
Practitioner Guidance
What to prioritise: Focus automation on the parts of the Concur review that are most likely to fail by hand, namely entitlement completeness, reviewer assignment, exception tracking, and revocation follow-through. If any of those steps still depend on memory or email, the process remains partially manual even if the approval itself is in a workflow tool.
What to verify: Make sure each review cycle produces evidence that can answer four questions cleanly: who was reviewed, what access was approved or removed, who approved it, and when the change took effect. If the output cannot be reconstructed without digging through inboxes or spreadsheets, the control is not yet strong enough for audit or for incident response.
Decision rule: If a Concur entitlement is business-critical, high privilege, or tied to sensitive payment or reimbursement data, treat delayed recertification as a real exposure condition, not a housekeeping issue. Automation should shorten the time between identifying excessive access and removing it, not merely create a prettier approval record.
Practitioner takeaway: The value of automating Concur access reviews is not process speed alone, it is reducing the window in which unjustified access survives without clear ownership, evidence, or remediation.
