Common Gaps in Azure Privileged Identity Management Deployments

Key Takeaways

Entra PIM covers the directory tier well. The gaps are everywhere else: Azure resource roles, app-specific data plane roles, and service principals and managed identities that hold permanent assignments outside the PIM activation workflow entirely.

Activation window defaults and missing approval workflows on tier-zero roles are the easiest wins in a PIM security review. Eight-hour activation on Global Administrator with no approval is not a hardened deployment. Just-in-time access means short windows and required sign-off, not eligible assignments with convenience settings.

PIM audit logs record who activated what. They do not record what the activated identity did. Without SIEM correlation of activation events against Azure activity logs, the audit trail records the door opening but not what was taken.

Frameworks like NIST 800-53 and the CIS Controls assume privileged access is managed end to end, across users, services, and workloads. The deployment does not get credit for the roles it did not enroll.

Quick Answer

What does a complete Azure privileged identity management review actually find?

Entra PIM is a good control. The gap is not the tool, it is the assumption that wrapping Global Administrator and a handful of directory roles in eligible assignments closes the privileged access management problem. In a real tenant audit, the same patterns appear every time: Azure resource roles still standing, service principals running Owner on production subscriptions, and audit logs that record activation events but never correlate them to what the activated identity actually did.

What Are the Most Common Gaps in an Entra PIM Deployment?

The most common gaps are scope stopping at directory roles, service principals and managed identities holding permanent assignments outside the PIM workflow entirely, activation windows set too long with no approval required on tier-zero roles, and audit logs that record activation but never correlate it to downstream activity. These patterns repeat across tenants of every size. None of them require new tooling to close. They require a deliberate second pass through the deployment that most teams skip because they assumed the first pass was enough.

The six gap categories that appear most frequently in live tenant audits:

  • Scope: PIM stops at directory roles, Azure resource roles and data plane assignments left standing
  • Activation: eight-hour defaults, no approval on tier-zero roles, justification fields that nobody reads
  • Service principals and managed identities: no eligible assignment model, permanent access, no activation flow
  • Break-glass accounts: credentials not split, no sign-in alerting, rotation forgotten after test use
  • Audit logs: activation recorded, downstream activity not correlated, SIEM missing one or two of the three log sources
  • Group complexity: role-assignable groups reused, permanent owners bypassing activation, nested groups hiding effective permissions

Scope Stops at Global Admin

The most common gap is scope. Azure privileged identity management gets enabled for Global Administrator, Privileged Role Administrator, a few directory roles, and then the project closes. The deployment plan, if there was one, never made it past the directory tier. Everything below that tier runs on permanent assignments. Teams that think of PIM coverage as a percentage of roles enrolled often discover they are at 90 percent of directory roles and 10 percent of the actual access surface.

Azure Resource Roles Left Standing

Azure RBAC assignments on subscriptions, resource groups, and individual resources are a separate surface. Owner, Contributor, and User Access Administrator on a production subscription is as dangerous in practice as a directory role. PIM supports Azure resource roles, but many tenants never enable the feature there. The result is a tidy directory tier with eligible assignments and an Azure plane that hands out standing Contributor to a dozen engineers because that is how the subscription was set up in 2021. The CIS Azure Benchmarks call out data plane controls for this exact reason. PIM should extend to those assignments, not just tenant-wide admin roles.

App-Specific Roles Are Never Enrolled

Key Vault access policies, Storage data plane roles, SQL AAD admins, and custom RBAC roles tied to specific services all sit outside the PIM project unless someone explicitly brings them in. These are the roles that move the data. They rarely appear on the first pass. The CIS Azure Benchmarks call out data plane controls for a reason. PIM should extend to those assignments, not just tenant-wide admin roles.

Activation Duration and Approval Are Too Loose

Eligible does not mean least privilege if activation lasts a full working day with no approval and no justification review.

Eight-Hour Windows by Default

The default maximum activation is often set high to reduce help desk noise. Eight hours means an admin activates in the morning, walks away from the desk, and the role stays live through lunch, through a coffee, through an unattended laptop. Shortening the window to one or two hours with the option to extend is one of the cheapest wins in a PIM review.

No Approval on Tier-Zero Roles

Approval workflows exist and cost nothing to turn on. Global Administrator, Privileged Role Administrator, and Security Administrator should never activate without a second pair of eyes. We regularly see tenants where approval is disabled on every role because it was considered friction during rollout. MITRE catalogs this failure mode under privilege escalation (TA0004): a standing or quickly activated admin role is the simplest path to tenant-wide control.

Justification Fields That Nobody Reads

Activation reasons are captured and ignored. "Routine work" appears in a thousand records. If nobody reviews the justifications, the field is theater. A quarterly review of activation reasons sampled against downstream changes closes the loop and turns a compliance artifact into a real control.

Service Principals and Managed Identities Outside the Workflow

PIM was designed around users. Any PIM security program that stops there is missing the majority of the identity surface in a modern Azure estate. Service principals and managed identities are not protected by the same activation and approval workflow as user roles. They do not go eligible, and they do not activate. They hold their assignments permanently. This is not a configuration choice. It is a fundamental architecture difference that PIM does not bridge.

Subscription-Wide Owner on App Registrations

A pipeline service principal ends up with Owner on a subscription because the developer needed to deploy a resource and the scope was never narrowed. The credential rotates, or does not, and the identity persists for years. MITRE ATT&CK T1078 (Valid Accounts) covers exactly this pattern: a legitimate machine identity with too much access, used as a foothold. The PIM dashboard does not show it because PIM does not own it.

Managed Identities with Cross-Subscription Reach

User-assigned managed identities get attached to resources across subscriptions to avoid credential handling. The blast radius grows quietly. PIM does not wrap the access. The identity does not expire, does not require activation, and does not surface in the usual access review cadence. This is the same problem as standing access for users, except there is no activation model to fall back on at all.

Federated Workload Identities

Workload identity federation removes secrets, which is a win. It does not remove the assignment. A GitHub or Terraform Cloud federated credential still needs a scoped role. When that role is Contributor on the subscription, the absence of a secret is not a meaningful control. Short-lived credentials reduce the credential risk; they do not address the permission scope. Both matter.

Break-Glass Accounts That Break

Every tenant has two or more break-glass accounts. They are excluded from conditional access, excluded from MFA in some designs, and excluded from PIM. They are also, in many tenants, not monitored.

Password Not Split and Not Rotated

Break-glass credentials are supposed to live in a safe, split between two custodians, and rotated after any use. In practice the password is in a shared vault entry that seven people can open. If any one of those seven leaves the company, the account should rotate. It rarely does. This is credential lifecycle management at its most basic, and it is failing on the most sensitive account in the tenant.

No Sign-In Alerting

A break-glass account should fire an alert on any sign-in, ever. Many tenants skip the alert because the account is expected to be quiet. That is the point. The alert is the whole control. An account that signs in with no alert is indistinguishable from an account that is being silently abused.

Audit Log Blind Spots

PIM writes a clean record of who activated what and when. The audit log guidance covers how to view it. The gap is what happens after the activation.

Activation Without Correlation

An admin activates User Access Administrator, makes a role assignment, and deactivates. The PIM log shows the activation. The Azure activity log shows the assignment. Nobody joins the two records. The control stops at the door.

SIEM Ingestion Missing the Full Trail

Entra audit logs, sign-in logs, and Azure activity logs each live in different pipes. Teams send one or two of the three to the SIEM and call it covered. The Verizon DBIR keeps identity front and center as the primary breach vector for a reason: detection works when the logs line up, not when they sit in separate blades with no join.

Reviews Run on Cadence, Not on Signal

Access reviews run quarterly. Attackers do not. A high-impact activation outside business hours should trigger a same-day review, not wait for the next quarterly cycle. The cadence model is a compliance artifact. The signal model is a security control.

Hybrid Identities and the On-Prem Bypass

Entra is half of the identity estate for many enterprises. The other half is on-prem Active Directory, synchronized through Entra Connect, with Tier 0 admins who never touch Entra roles at all. A complete Azure identity governance program has to account for both halves or it is not governing the estate, it is governing the half that is easier to see.

Domain Admins with Synced Accounts

A Domain Admin with a hybrid account can push changes into the Entra tenant through sync. PIM does not cover the on-prem side. The on-prem privileged tier has its own model, or does not, and the two models rarely align. PIM compliance at the directory tier and exposed standing access at the domain level is not a hardened environment. It is a perimeter with one gate guarded and the fence missing.

Azure Arc Extending the Perimeter

Azure Arc-managed servers and Kubernetes clusters bring on-prem workloads into Azure RBAC. The roles on those Arc resources are often assigned permanently to service accounts that came from the on-prem design. The NIST Zero Trust model treats every access as untrusted until proven. Hybrid deployments often carry an implicit trust that PIM cannot see, and that implicit trust is where lateral movement paths form.

Group-Based Privilege Is Where Audits Fail

Groups are how real organizations assign access. PIM for Groups and role-assignable groups exist for this reason. They also introduce their own gaps.

Role-Assignable Groups Used as Regular Groups

A role-assignable group gets created for a specific directory role, then reused for other access because it is convenient. Now the membership expands and everyone in the group inherits the directory role. Role-assignable groups should hold one purpose each. When they hold many, the PIM activation model covers only the role it was built for, and the rest of the access runs without any controls.

PIM for Groups with Permanent Owners

PIM for Groups puts the membership behind activation. The owner of the group often does not. A standing owner can add members, which defeats the activation model. Owners should be eligible, approval should be required, and ownership should appear in the same review cadence as the role itself.

Nested Groups Hiding the Real Reach

Nested group structures turn a narrow assignment into a wide one. Without a flat view of effective permissions, the PIM record says "eligible for Group A" and the real access is through Group A to Group B to a privileged role that nobody reviewed. The OWASP authorization guidance treats transitive permissions as first-class risk for this reason. Effective permission analysis, not just direct assignment analysis, has to be part of the audit.

How Token Security Approaches the Gaps Entra PIM Leaves Open

The Challenge

PIM handles the human privilege story well. It was built for it. The gaps it leaves are structural, not configuration issues: service principals and managed identities do not fit the activation model, federated workload identities remove secrets but not overprivileged assignments, and the audit trail for what happens after activation lives in a separate system. These are gaps that no PIM configuration change closes, because they are outside the scope PIM was designed for. Azure identity governance that stops at the PIM dashboard is leaving the machine plane unmanaged.

The Approach

Token Security sits alongside PIM and covers the machine identities PIM does not treat as first-class members. Continuous discovery finds the service principals, managed identities, federated workload credentials, and agent identities across the tenant and across connected clouds. Contextual intelligence scores the blast radius of each one, flagging the pipeline token that holds Owner on a production subscription and the managed identity that has accumulated cross-subscription reach nobody intended.

  • Discover: continuous NHI inventory across Entra, Azure, CI/CD, SaaS, and AI platforms, covering the identities that do not appear in the PIM dashboard
  • Understand: entitlement mapping and blast-radius analysis per identity, showing which service principals touch CDE systems and which managed identities have cross-subscription reach that was never intended
  • Lifecycle governance: catches the app registrations that outlive their owners and the secrets that rotate on paper but not in reality

The Outcome

A human plane that stays in PIM with a machine plane that has somewhere to live. The two programs run in parallel and together cover the full privileged access surface that neither covers alone.

What Security Teams Find When They Look at the Machine Plane Alongside PIM

Getting Signal Without Noise on Machine Identity Risk

The service principal and managed identity gap is the one security teams most often underestimate during a PIM deployment. The assumption is that wrapping directory roles in eligible assignments is most of the problem. The first audit conversation usually reveals that 80 percent of the identity risk in a tenant is sitting in permanent assignments on the Azure plane and in identities PIM has never touched. Getting meaningful signal from that population, without creating more alert volume than a team can process, is the core challenge.

"Token Security has enhanced our security by providing us accurate and relevant visibility into machine identity risks, something I have yet to see from other vendors. It's the first service I've seen that delivers on the widely-made claim of finding machine identity risk. It provides us with the right amount of detail to mitigate issues without burdening us with tens of rows of useless alerts." — Jonathan Jaffe, CISO at Lemonade

This is the operational problem PIM does not solve for non-human identities. PIM produces a clean activation log for directory roles. For the service principals, managed identities, and federated credentials that make up the majority of the privilege surface in a mature Azure estate, there is no equivalent record until something goes wrong. Getting accurate, actionable signal on that population, without it becoming tens of rows of noise, is what closes the gap the PIM deployment left open.

Extending Existing Identity Security Beyond What Current Tools Cover

The challenge of an incomplete PIM deployment is not usually that the tool is wrong. It is that the tool was scoped to what the team knew it needed at the time. Azure privileged identity management covers the directory tier well. The machine layer, the service principals, the cross-subscription managed identities, the federated workload credentials, accumulates outside the program's boundary until someone runs an audit and finds it. Security leaders who have worked through this recognize the pattern: existing tools have real value, and they have real ceilings.

"Token helps customers bolster the management of their non-human identity security challenges, by providing increased visibility, critical risk prevention, and overall stronger security measures. Their approach surpasses all existing identity security solutions." — Al Ghous, SVCI Co-Founder and CISO

The SVCI framing maps directly to what a complete PIM review requires. Bolstering existing management, not replacing it. PIM remains the right tool for the human privilege story. The machine plane requires something built for machine identities, running continuously alongside it.

Why the NHI Gap Keeps Widening

A clean Azure privileged identity management deployment covers a real fraction of privileged risk. It does not cover all of it. The gaps above are operator-level items that a quarter of focused work can close. The harder work is accepting that Entra PIM was built around user roles, that the modern cloud estate is mostly non-human, and that a complete PIM security and Azure identity governance program has to include both.

Frameworks like NIST 800-53 and the CIS Controls assume privileged access is managed end to end, across users, services, and workloads. The deployment does not get credit for the roles it did not enroll. As AI agents and workload identities multiply the non-human identity population further, PIM's coverage fraction shrinks. Azure identity governance that does not account for the machine plane does not close the gap. It just does not know the gap is there.

FAQs

Does Entra PIM cover service principals the same way it covers users?

No. PIM workflows (eligible assignment, activation, approval) are oriented around user accounts and role-assignable groups. Service principals and managed identities hold their role assignments directly and do not activate through PIM. Coverage for workload identities has been evolving, but it is not equivalent to the user flow and should be planned for separately with a dedicated NHI governance layer.

What is a reasonable maximum activation duration for tier-zero roles?

One to two hours is a reasonable starting point for Global Administrator and equivalent roles, with the option to extend once if needed. Eight-hour windows are common defaults and usually too long. Pair a short window with a required justification and approval for the highest-impact roles. The goal is that any standing access during an activation window is brief enough to be reviewed in context.

How should break-glass accounts be monitored?

Every sign-in should alert. These accounts are expected to be unused for long periods, so any authentication is a signal worth reviewing immediately. Credentials should be split between custodians, stored offline, and rotated after any real or test use. The absence of an alert on break-glass sign-in is not a quiet environment. It is an unmonitored one.

Can PIM alone satisfy least privilege requirements in NIST or CIS frameworks?

PIM helps, but it does not satisfy the full requirement. Standards assume privileged access management is controlled across users, services, and workloads. Programs that rely only on PIM typically still have standing access on Azure resource roles, app-specific roles, and non-human identities. A combined approach covering the human plane through PIM and the machine plane through dedicated NHI governance is what the frameworks assume.
