TL;DR: Zero Trust only works when identity decisions are continuously verified, and the source article argues that identity governance supplies the visibility, least-privilege enforcement, and automated reviews needed to make that practical across cloud, SaaS, and on-prem environments, according to SecurEnds. The governance gap is not conceptual, it is operational: without access inventory, review cadence, and lifecycle control, Zero Trust remains a slogan rather than a control model.
Editorial analysis by NHI Mgmt Group, based on content published by SecurEnds: “How Identity Governance Powers Zero Trust Security Models”.
Key questions
Q: What breaks when Zero Trust is implemented without identity governance?
A: Zero Trust breaks when the policy engine is enforcing stale or incomplete identity data.
Q: Why do unreviewed privileges undermine Zero Trust in hybrid environments?
A: Unreviewed privileges undermine Zero Trust because access often survives role changes, contractor churn, and offboarding events.
Q: What should Zero Trust programmes measure to know whether identity governance is working?
A: Measure how quickly access is provisioned, reviewed, and revoked, and whether privilege is actually reduced over time.
Practitioner guidance
- Build a complete access inventory Map every user, contractor, service account, and bot to the systems they can reach so Zero Trust decisions start from current entitlement data.
- Tie recertification to lifecycle events Trigger access reviews when people change roles, join projects, or leave so approval cadence tracks real organisational change.
- Automate keep, adjust, revoke workflows Make reviewers select one of those outcomes and write the decision back into the identity system so review results actually change access.
Bottom line: Zero Trust depends on identity governance to turn verification into enforceable access control across hybrid environments.

Identity governance is the missing enforcement layer in Zero Trust. Zero Trust asks organisations to verify every request, but verification without inventory and review cadence is incomplete. Access control becomes credible only when every entitlement can be traced to a purpose, an owner, and an expiry condition. The practitioner conclusion is that Zero Trust architecture should be judged by whether identity governance can enforce it, not whether the policy language sounds right.
A few things that frame the scale:
- 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: Should organisations prioritise access governance before expanding automation?
A: Yes, because automation increases the speed at which access can be created, inherited, and forgotten. If governance is weak first, automation simply scales unmanaged privilege. Organisations should define ownership, review cadence, and revocation rules before allowing more automated provisioning.
