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.
Editorial analysis by NHI Mgmt Group, based on content published by Orca Security: “CIEM vs IAM vs PAM: What’s the Difference (and Do You Need All Three)?”.
Key questions
Q: What breaks when IAM and PAM are the only identity controls in cloud environments?
A: Cloud teams lose visibility into effective permissions.
Q: Why do excessive cloud entitlements increase blast radius?
A: Excessive entitlements let an identity reach more systems, data, and admin functions than its job requires.
Q: How do security teams know if CIEM is actually reducing ransomware risk?
A: Look for fewer unused entitlements, lower privilege concentration in service accounts, and faster revocation of excessive cloud access.
Practitioner guidance
- Map effective permissions across cloud accounts Compute what each identity can actually do after roles, inherited policies, and trust relationships resolve.
- Prioritise non-human identities for entitlement review Treat service accounts, workload roles, and CI/CD identities as first-class subjects in access governance because they often hold broad access that human-centric reviews miss.
- Pair PAM with entitlement analysis Use privileged access controls to govern how admins operate, then verify whether the underlying cloud entitlements are broader than the work actually requires.
Bottom line: CIEM addresses the cloud entitlement layer that IAM and PAM do not cover, especially where effective permissions are broader than assigned roles.

CIEM is the missing governance layer for cloud entitlements, not another access control brand. IAM still authenticates identities and PAM still protects privileged use, but neither was built to continuously compute effective cloud permissions. That leaves a structural gap in multi-cloud environments where access is assembled from roles, trust paths, and machine identities. Practitioners should treat entitlement visibility as a distinct control plane, not as an add-on to login or privilege workflows.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How should organisations divide responsibility between IAM, PAM, and CIEM?
A: Use IAM to establish identities and base access, PAM to control privileged human use, and CIEM to continuously right-size cloud entitlements. That division prevents teams from overloading one tool with three different jobs. The governance win comes from layering them, not from expecting any one of them to explain the full cloud access picture.
