TL;DR: IAM authenticates identities, PAM protects privileged sessions, and CIEM analyzes the cloud entitlements that can quietly expand blast radius across human and machine identities, according to Orca Security. The governance gap is no longer theoretical: cloud teams need entitlement visibility alongside access control and privilege containment.
NHIMG editorial — based on content published by Orca Security: CIEM vs IAM vs PAM at a glance
Questions worth separating out
Q: How should security teams govern cloud entitlements for non-human identities?
A: Security teams should govern cloud entitlements by computing effective permissions, not just reviewing assigned roles.
Q: Why do IAM and PAM leave cloud permission gaps?
A: IAM and PAM were designed around authentication and privileged session control, not the full entitlement graph created by cloud policies.
Q: What breaks when cloud teams rely on IAM alone?
A: Relying on IAM alone leaves teams blind to effective access and permission drift.
Practitioner guidance
- Separate entitlement review from access provisioning Review effective permissions independently of joiner-mover-leaver workflows so cloud roles, inherited policies, and trust paths are assessed after they combine, not only when they are assigned.
- Inventory non-human identities as first-class subjects Build a distinct register for service accounts, CI/CD roles, workload identities, and functions, then classify which of those identities can assume additional roles or reach sensitive resources.
- Reconcile PAM coverage with cloud role reality Compare vaulted privileged accounts against cloud identities that can perform equivalent actions without a password or session checkout, then close the gaps where PAM has no visibility.
What's in the full article
Orca Security's full article covers the operational detail this post intentionally leaves for the source:
- The side-by-side mechanics of IAM, PAM, and CIEM across cloud environments and account models.
- The practical differences between authentication, privileged session control, and effective permission analysis.
- The related acronym map for PIM, IGA, CSPM, SIEM, and ITDR in cloud identity programmes.
- The specific scenarios where CIEM exposes over-permissioned human and machine identities that other controls miss.

CIEM is the cloud-native entitlement layer that IAM and PAM were never built to provide. IAM governs who can authenticate and PAM governs how privileged sessions are used, but neither can reliably compute effective permissions across multi-cloud estates. That leaves service accounts, workload identities, and inherited role chains outside the centre of gravity. The implication is that cloud identity governance must be measured by effective access, not by the account model alone.
A few things that frame the scale:
- 70% of organisations grant AI systems more access than they would give a human employee performing the exact same job, according to the 2026 Infrastructure Identity Survey.
- A separate 2024 NHI survey found that 35.6% of organisations cite consistent access across hybrid and multi-cloud environments as their top non-human identity challenge.
A question worth separating out:
Q: Who should own CIEM in a mature identity programme?
A: CIEM should be owned jointly by cloud security, IAM, and identity governance teams because it sits between provisioning, privilege management, and entitlement reduction. The objective is not to replace existing controls but to reconcile them against actual cloud access so that account lifecycle, privileged access, and machine identity governance all share one entitlement picture.
