When certification is fragmented across PAM and IGA tools, application owners can miss required reviews or face inconsistent evidence for the same identity. That weakens audit readiness and can leave privileged access outside normal governance cycles. The practical failure is not just extra work, but a higher chance that inappropriate entitlements remain active long enough to create compliance findings or security exposure.
Where the split creates a control failure
The core problem is not that PAM and IGA both have certification features, it is that they often certify different views of the same access. PAM usually governs privileged sessions, shared admin accounts, vault-managed credentials, and time-bound elevation. IGA usually governs broader entitlement reviews, ownership, recertification, and audit evidence. When those views are split, the organisation can no longer say with confidence that one review cycle covers the full access path.
That gap matters most when a privileged account is wrapped in one tool but owned or certified in another. A reviewer may approve the entitlement in IGA while the privileged credential remains active in PAM, or revoke access in PAM while the upstream entitlement persists in IGA. Either way, the organisation ends up with fragmented assurance rather than a single defensible record of access state.
For broader context on the lifecycle and governance side of this problem, see Ultimate Guide to NHIs, Lifecycle Processes for Managing NHIs and Ultimate Guide to NHIs, Regulatory and Audit Perspectives; both show why ownership, review cadence, and evidence quality must line up across control planes.
Why auditors and application owners feel the break first
In practice, the first symptoms are missed reviews, duplicated attestations, and evidence that does not reconcile cleanly. Application owners are asked to confirm who approved access, but the answer depends on which tool recorded the entitlement and which tool recorded the privileged credential. That forces manual reconciliation and creates room for inconsistent treatment of the same identity or account.
This is also where audit readiness weakens. If an auditor asks whether a privileged path was reviewed and removed on time, the organisation may have two partial answers instead of one complete one. The result is often a finding about control design or operating effectiveness, even when each team believes it completed its own part correctly. The control failed because the governance boundary, not just the approval process, was fragmented.
That governance split is discussed in NHIMG’s Cloud Compliance Pulse 2025 and Ultimate Guide to NHIs, both of which emphasise access review, recertification, and posture visibility as linked control outcomes rather than isolated tasks.
One useful signal of scale is NHIMG’s finding that only 5.7% of organisations have full visibility into their service accounts. That is not a certification statistic by itself, but it explains why fragmented review records so quickly become a governance problem: if the inventory is incomplete, certification can only ever be partial.
How to realign certification so the same access is governed once
The practical fix is to define one system of record for review ownership and then map both PAM and IGA evidence into it. The reviewer should not need to decide which tool is authoritative for each access path. Instead, the process should make clear which object is being reviewed, what privilege it confers, where the evidence lives, and what event counts as removal or approval.
- Use one review owner per access path, even if multiple tools enforce it.
- Tie privileged credential status to the entitlement record so approval and revocation move together.
- Require reconciliation between PAM removals and IGA recertification outcomes before closure.
- Keep evidence that shows the exact account, privilege scope, approval date, and removal date.
Practitioners should also treat exceptions carefully. If a privileged path cannot be represented in both tools cleanly, it is usually a design issue, not just an operational nuisance. That is the point at which governance should escalate the integration gap rather than accept a one-off manual workaround.
Practitioner takeaway: certification is only defensible when the organisation can prove that the same privileged access was reviewed, approved, and, if needed, removed across both the entitlement and credential layers without relying on manual reconciliation.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
CIS Controls v8 and NIST CSF 2.0 set the technical controls, while ISO/IEC 42001:2023 define the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| CIS Controls v8 | 6 — Access Control Management | PAM and IGA split directly weakens access review and revocation control. |
| Recommendation — Consolidate access review and revocation evidence under one access control process. | ||
| NIST CSF 2.0 | PR.AC — Access Control | The issue is fragmented enforcement and review of who can access privileged resources. |
| GV.RM — Risk Management Strategy | Split certification creates governance and audit risk that must be managed explicitly. | |
| Recommendation — Align privileged access approvals and removals to a single access control model. Define ownership and evidence rules for cross-tool access certification. | ||
| ISO/IEC 42001:2023 | 6.1 — Actions to address risks and opportunities | When AI governance is not the topic, omit. |
