Zero Trust coverage gaps: what IAM teams are missing

TL;DR: Many organisations say they have implemented Zero Trust, but JumpCloud argues that partial coverage across IAM, device trust, network access, PAM, and visibility leaves material gaps. The deeper issue is not whether Zero Trust is adopted, but whether it is enforced consistently across the full access surface.

Editorial analysis by NHI Mgmt Group, based on content published by JumpCloud: “The Five Must-Haves of a Zero Trust Program”.

Key questions

Q: How should security teams replace perimeter-based access control with a Zero Trust model in distributed environments?

A: Security teams should move from network location as the trust signal to identity, device posture, and continuous verification.

Q: Why does Zero Trust fail when only privileged users are covered?

A: Because privileged users are only one part of the access surface.

Q: What are the signs that a Zero Trust programme is not being enforced consistently?

A: A Zero Trust programme is likely failing when access still depends on trust by location, broad entitlements, or one-time authentication.

Practitioner guidance

  • Define Zero Trust coverage by access path Map every user, device, application, privileged session, and service path to an explicit control owner and policy decision point.
  • Extend MFA beyond high-risk accounts Require MFA on all relevant access points, including ordinary users, administrative workflows, and remote sessions.
  • Tie device trust to access authorization Block access when OS version, patch status, encryption, or MDM enrollment fails policy.

Bottom line: Zero Trust fails operationally when organisations stop at a subset of users or systems and leave other access paths governed by legacy assumptions.

Partial Zero Trust is a control architecture problem, not an authentication problem. The article shows that MFA alone does not create Zero Trust if the rest of the access path still relies on broad trust. In identity governance terms, the failure is selective enforcement across policy layers, not weak login mechanics. Practitioners should treat coverage completeness as the real control objective.

A few things that frame the scale:

  • 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation, according to the Ultimate Guide to NHIs.

A question worth separating out:

Q: What should teams do when Zero Trust controls exist but coverage is uneven?

A: Treat it as a governance problem, not a tuning issue. Reconcile which identities, devices, applications, and privileged workflows remain outside the policy boundary, then close those exceptions before adding more tools. If a control does not apply consistently, it is not yet part of the operating model.
