Microsoft Entra ID Governance includes several controls that all answer versions of “who should have access,” but they operate at different points in the access lifecycle. Privileged Identity Management (PIM) controls privileged role eligibility and activation. Access Reviews recertify access that already exists. Entitlement Management packages resources into requestable access with approval, assignment, expiration, and review rules.

The current SC-300 objectives cover identity governance and privileged access, so the useful exam and operational skill is choosing the control that matches the governance problem. Trying to make one feature do all three jobs usually creates either too much standing access or too much administrative work. A good SC-300 identity-governance practice scenario asks whether the requirement is eligible role activation, periodic access certification or a new entitlement for an external collaborator.

PIM reduces standing privilege

Use PIM when the core problem is privileged access to Microsoft Entra roles, Azure resource roles, or supported privileged group scenarios. The design goal is to keep highly privileged permissions eligible until the person actually needs them rather than assigning them permanently.

An activation can be governed with controls such as a maximum activation duration, multifactor authentication, justification, approval, notifications, and Conditional Access. This changes the risk model. A user can be authorized to become a Privileged Role Administrator or another high-impact role without carrying that permission during every normal workday.

PIM is therefore primarily about privilege elevation and privileged assignment lifecycle. It helps answer questions such as: Who can become an administrator? Under what conditions? For how long? Who approved it? The feature is strongest when privileged work is occasional, auditable, and separable from day-to-day identity use.

A useful design distinction inside PIM is eligible versus active assignment. An eligible assignment gives a user the right to activate later under policy; an active assignment grants the role directly for its configured period. Organizations that convert every administrator into permanently active access gain little from PIM. Use eligibility for routine privileged responsibilities and active assignments only when their operating purpose is understood. A PIM role activation record shows when elevated permissions became active, not which administrative operations were performed. Correlate activation history with relevant audit and resource logs when investigating a privileged action.

Access Reviews recertify what already exists

Access Reviews are the right control when access has already been granted and the organization needs a recurring decision about whether it should continue. Reviewers can attest to access for groups, enterprise applications, guest users, access-package assignments, and supported role scenarios.

The important idea is continued need. A quarterly application review does not grant a new entitlement; it asks whether the current assignment is still appropriate. A guest review asks whether an external collaborator still needs access. A group review asks whether membership still reflects job responsibilities.

Reviews can be configured with recurrence, reviewers, decision helpers, and actions that apply the outcome. That allows governance teams to move beyond spreadsheets and email campaigns. The feature is especially valuable where job changes, project endings, contractor turnover, and accumulated group memberships make access drift likely over time.

Entitlement Management governs requests and packages

Entitlement Management is designed for access that should be requested, approved, assigned for a bounded period, and removed or reviewed according to policy. It organizes resources such as groups, applications, and SharePoint sites into access packages that represent a business need rather than a collection of individual permissions.

An access package can define who may request access, who approves it, how long assignments last, whether extensions are allowed, and whether access reviews are required. That makes it a strong fit for project onboarding, partner collaboration, temporary business roles, and repeatable bundles of resources.

The distinction from Access Reviews is important. Entitlement Management can include review steps, but its broader job is lifecycle orchestration around the package. The review capability answers “should this assignment continue?” while the access package answers “what bundle is requested, by whom, under which approval and expiration rules?”

The review target should match the control objective. A resource owner may be the best reviewer for application access, while a manager may be better for role-based business access. Guest reviews may need sponsorship information because the external identity itself cannot prove continuing business need. Review settings should also define what happens when a reviewer does not respond; otherwise a recurring control can quietly become “access continues by default.”

PIM can include reviews without replacing Access Reviews

PIM includes access-review functionality for privileged roles, which can make the product boundaries look blurry. The difference is scope and operating context.

A privileged-role review in PIM is centered on administrative and Azure resource role assignments. General Access Reviews extend recertification to broader identity-governance targets such as group membership, enterprise application access, and guest access. Entitlement Management can also invoke reviews for assignments created through access packages.

Instead of memorizing the UI location, follow the object being governed. If the object is a privileged role, PIM is usually the center of gravity. If the object is ordinary membership or application access that already exists, Access Reviews are usually the direct fit. If access should be requested as a policy-governed package, Entitlement Management is the lifecycle framework and a review may be one step inside it.

Separate assignment from activation

A common design mistake is treating “has a role assignment” and “is actively using the role” as the same event. PIM deliberately separates them.

An eligible assignment answers whether the user is allowed to activate the role during the assignment period. Activation is the temporary step that grants the effective privileged access, subject to the configured activation requirements. This separation is useful for administrators who may need elevated permissions periodically but should not operate with them continuously.

That model also improves investigation. An auditor can distinguish who was eligible, who actually activated, when activation occurred, and what controls were satisfied. It creates a clearer privilege story than permanent assignments where the organization cannot easily tell whether high-impact permissions were truly needed on a given day.

Build governance around lifecycle events

Identity governance is strongest when access changes are tied to predictable lifecycle events. A new project can trigger an access-package request. A privileged engineering responsibility can justify PIM eligibility. A quarterly control can trigger access reviews. A role change or project end can remove assignments automatically or expose them for recertification.

Think in terms of joiner, mover, leaver, and temporary-access scenarios rather than configuring each feature independently. Entitlement Management can standardize how people obtain a business bundle. Access Reviews can detect access that no longer matches need. PIM can ensure that even approved administrators do not carry standing privilege unnecessarily.

The tools complement one another because lifecycle risk appears at multiple points: access can be granted too broadly, retained too long, or exercised with too much privilege. A mature governance design addresses all three failure modes.

For movers, lifecycle sequencing is especially important. A user who changes departments may need new access packages, removal from old groups, recertification of exceptions, and a change in privileged eligibility. No single feature automatically understands every business transition. Provisioning, Lifecycle Workflows, access packages, reviews, and PIM can all participate, but the organization still needs an authoritative rule for which system initiates each change and which system owns the resulting access decision.

Match reviewers and approvers to the decision

Governance fails when the person making the decision lacks enough context. An application owner may understand whether a user needs a business application. A manager may understand employment responsibilities. A privileged-role owner may understand whether an engineer still needs administrative capability. A project sponsor may understand whether a contractor should retain an access package.

Choose approvers and reviewers according to the resource and decision, not simply according to who is easiest to configure. Also define what happens when reviewers do not respond. Recurring reviews with weak ownership can become ceremonial controls where access persists because nobody makes a meaningful decision.

Good governance evidence should show why access was granted, who approved or reviewed it, the duration or recurrence, and what happened when the decision changed. That is more valuable than simply proving a feature was enabled.

Use overlap deliberately, not accidentally

Real environments often use all three capabilities together. Consider a consultant who joins a six-month project. Entitlement Management can provide a package containing project groups and applications with sponsor approval and an expiration date. Access Reviews can recertify the assignment midway through the engagement. If the consultant occasionally needs a privileged Azure role, PIM can make that role eligible with time-limited activation and stronger controls.

The overlap is intentional because each feature governs a different risk: package assignment, continuing need, and privileged execution. Problems arise when administrators duplicate the same decision in multiple places without a clear operating model, creating conflicting expiration dates, unclear ownership, or multiple review campaigns for the same access.

Document which system owns each decision. That makes automation and audit evidence easier to interpret.

Choose the control by asking one precise question

A useful selection model is:

• PIM: “How do we avoid permanent high-impact privilege while still allowing approved users to elevate when needed?”
• Access Reviews: “How do we periodically verify that existing access should continue?”
• Entitlement Management: “How do we package, request, approve, expire, and govern access as a repeatable business process?”

If the scenario contains more than one of those questions, combine the capabilities rather than forcing one tool to absorb another tool’s job. The most defensible Entra governance architecture is not the one with the most controls enabled; it is the one where assignment, activation, review, expiration, and ownership each have a clear home.
