TL;DR: Unosecur argues that fragmented IAM leaves authentication, governance, privileged access and runtime control operating in separate silos, which creates blind spots after login and slows response across hybrid human and non-human environments. The practical shift is from system-centric administration to continuous, access-centric identity governance across the full lifecycle.
Editorial analysis by NHI Mgmt Group, based on content published by Unosecur: “IAM Fragmentation Crisis”.
Key questions
Q: How should teams reduce IAM fragmentation across authentication, governance and PAM?
A: Start by treating IAM as one lifecycle with shared identity data, not as a set of isolated control domains.
Q: Why do separate identity tools create blind spots after login?
A: Because many tools stop where their own function ends.
Q: What breaks when access reviews are disconnected from usage logs?
A: Reviewers lose the evidence needed to tell whether access is still justified, exercised, or simply left in place.
Practitioner guidance
- Map identity control boundaries Document where authentication, IGA, PAM and policy enforcement are owned separately, then identify the data handoffs each team depends on.
- Connect lifecycle events to usage evidence Tie access review and removal decisions to application usage, ticket closure and runtime telemetry so entitlements are not managed from stale records.
- Extend governance to non-human identities Apply the same lifecycle discipline to service accounts, tokens and other NHIs that you already expect for employee access.
Bottom line: The article's core warning is that IAM fragmentation creates a control-plane gap after authentication, where review and enforcement no longer share the same evidence.

- The article's deeper examples of how IGA, PAM and policy enforcement diverge across separate operating teams
- The full lifecycle framing for credential issuance, renewal and contextual permission removal
- The discussion of how hybrid deployment patterns complicate centralised identity governance
- The article's treatment of non-human and agentic identity requirements in a unified model

Fragmented IAM is no longer an operating-model nuisance. It is a control-plane failure. When authentication, governance, PAM and enforcement are owned as separate domains, each team optimises its own pillar while the identity lifecycle remains fragmented. The result is a system that can issue access but cannot consistently govern what happens after access is granted. Practitioners should treat fragmentation as a structural governance defect, not a tooling inconvenience.
A few things that frame the scale:
- Organisations maintain an average of 6 distinct secrets manager instances, creating fragmentation that undermines centralised control, according to the State of Secrets in AppSec.
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How do NHI and human identity governance differ in a unified control plane?
A: The lifecycle logic is similar, but NHIs usually move faster and carry more ephemeral credentials, so governance has to be more continuous and more automated. Human identity programmes can tolerate slower review rhythms; NHI and agentic access cannot.
