What is Microsoft Entra PIM? How Privileged Identity Management Helps Secure Elevated Access

Microsoft Privileged Identity Management (PIM) is a Microsoft Entra ID Governance solution that enables organisations to securely manage privileged access through just-in-time activation, approval workflows, and auditing of administrative roles.

Privileged access remains one of the most valuable targets for attackers. Whether through credential compromise, misconfiguration, or insider activity, permanent administrative access can significantly increase the impact of a security incident.

What is Microsoft Entra Privileged Identity Management?

Microsoft Privileged Identity Management (PIM) is a service in Microsoft Entra ID that enables organisations to manage, control, and monitor access to privileged roles.

These include:

• Microsoft Entra ID (directory) roles
• Azure RBAC roles (subscriptions, resource groups, resources)
• Privileged group memberships via PIM for Groups

Rather than granting permanent access, PIM allows users to be assigned roles as eligible, meaning access must be explicitly activated when required. Elevation can then be controlled through additional measures such as Multi-Factor Authentication, approval workflows, or time bound assignments.

Why Privileged Access is a Security Risk

In many environments, administrative roles are assigned permanently “just in case” someone needs them. Over time, this can lead to:

• Privilege creep, where users gradually accumulate access rights they no longer need as they change roles or responsibilities. Over time, this can result in individuals retaining excessive permissions, increasing the likelihood of accidental changes, misuse, or unauthorised access to sensitive resources.
• An expanded attack surface, where compromised administrative accounts can provide attackers with broader access across systems and data. Because privileged accounts often have elevated permissions, a single breach can lead to significant security incidents.
• Audit and compliance challenges, where it becomes difficult to demonstrate who had access to specific resources, when that access was used, and whether it was appropriate. This lack of visibility can hinder investigations and make compliance reporting more complex.

Minimising permanent administrator access and treating identity as a security boundary supports compliance with Zero Trust principles.

How does Microsoft Entra PIM Work?

PIM works by changing how a role is held rather than what it can do. Every assignment falls into one of four types:

• Permanent active – the role is held continuously, with no expiry. (However, this is standing administrative access and what PIM aims to reduce.)
• Permanent eligible – the user can activate the role whenever needed, and holds no permissions until they do.
• Time-bound active – the role is held continuously (no activation required), but only until a set expiry date.
• Time-bound eligible – the user can activate the role, but only within a defined window, after which the eligibility is removed.

Where a user is eligible, they must request activation before the role takes effect. That request can be gated by Multi-Factor Authentication, require a written justification or ticket reference, and be routed to a nominated approver. Once granted, the role applies for a limited period and is revoked automatically when it expires.

Each of these steps is written to the PIM audit logs, giving a clear record of who elevated, when, for how long, why, and who approved it. That record supports both incident investigation and compliance reporting.

Core PIM Capabilities

What Roles and Resources Can PIM Protect?

PIM covers Microsoft Entra ID directory roles, Azure RBAC roles, and privileged group memberships through PIM for Groups. Because many Microsoft services honour group-based access, PIM for Groups also extends just-in-time control to downstream platforms such as Purview, Defender and Intune RBAC. Custom Entra roles and custom Azure role definitions can be made eligible in the same way as built-in ones.

Common PIM Use Cases

Some of the most effective uses of PIM we see in practice include:

• Replacing permanent Global Administrator assignments with eligible access

• Protecting sensitive Azure subscriptions using PIM controlled RBAC roles

• Managing privileged group membership used by downstream services including Purview, Defender and Intune RBAC.

• Supporting compliance requirements through access reviews and audit trails

  Microsoft provides deployment guidance to help organisations phase PIM adoption safely and avoid operational disruption.

Key Considerations Before Enabling PIM

• PIM requires Microsoft Entra ID P2 (or equivalent) licensing often achieved through existing E5, E7 or Defender Suite licenses.
• Break-glass (emergency access) accounts should be excluded from PIM.
• Implementation should balance security and usability, with consideration for the end user experience.
• If implemented PIM should be carefully planned, tested, and rolled out gradually across the organisation to minimise disruption and negative impact.

Privileged access presents a significant security risk if not properly controlled. Microsoft Privileged Identity Management helps address this by enforcing just in time access, improving visibility, and strengthening governance over privileged roles.

With careful planning and a phased rollout, organisations can reduce reliance on permanent access and enhance their overall security posture without impacting user experience.

FAQ

What is Microsoft Entra PIM?

Microsoft Entra PIM is a privileged identity management service that helps organisations manage, control and monitor access to privileged roles across Microsoft Entra ID, Azure and Microsoft services.

What is the difference between PIM and PAM?

PIM focuses on managing privileged identity and role activation, particularly within Microsoft Entra and Azure environments. PAM is a broader category that can include vaulting, session recording, credential rotation, endpoint privilege management and privileged account governance.

What is just-in-time access?

Just-in-time access gives users privileged permissions only when they need them and only for a limited period, reducing the risk associated with standing administrative access.

Does Microsoft Entra PIM require a licence?

Yes. Microsoft Entra PIM requires appropriate licensing. Organisations should check their Microsoft licensing position before planning implementation.

What are common PIM implementation mistakes?

• Enabling PIM across all roles at once instead of piloting and expanding in phases.
• Including break-glass accounts, leaving no reliable route back in during a lockout.
• Making roles eligible at subscription or tenant scope where a narrower scope would be sufficient.
• Leaving activation durations at the maximum, so elevation outlasts the task.
• Relying on a single approver, causing activation requests to stall out of hours.
• Converting roles to eligible without first reviewing who holds them, carrying existing privilege creep into the new model.
• Assuming Entra ID P2 licensing is in place without confirming coverage.

Which roles should be protected with PIM first?

High-impact roles such as Global Administrator, Privileged Role Administrator, Security Administrator, subscription Owner and User Access Administrator should usually be prioritised.

Should break-glass accounts be managed by PIM?

Emergency access accounts should usually be excluded from PIM so they remain available during lockout or service disruption scenarios, but they should be tightly controlled and monitored.

How should organisations roll out Microsoft Entra PIM?

A phased rollout is recommended. Start by reviewing current privileged access, piloting PIM with a small group, testing activation workflows, communicating changes, and then expanding across roles and resources.
