Privileged Identity Management on a Small Business Budget

Small businesses often assume Microsoft Entra Privileged Identity Management is an enterprise-only security tool.

It sounds expensive, complicated and designed for organisations with large security teams. In reality, PIM can be especially valuable in a small business because one compromised administrator may otherwise have permanent access to almost the entire Microsoft 365 environment.

Privileged Identity Management, usually shortened to PIM, replaces permanent administrative access with temporary, controlled role activation. An employee can remain eligible for an administrator role but receive its permissions only when they need to complete an approved task.

The challenge is using PIM where it delivers the greatest value without buying unnecessary licences or building an approval process that slows routine support work.

What Is Microsoft Entra Privileged Identity Management?

Microsoft Entra PIM provides time-limited and, where required, approval-based access to privileged roles across Microsoft Entra ID, Azure and supported Microsoft online services.

Instead of making somebody a permanent Exchange Administrator, for example, you can make them eligible for the role. When they need to perform Exchange administration, they activate it for a limited period.

The activation can require:

• Multifactor authentication
• A business justification
• A service-ticket reference
• Approval from another person
• A limited activation duration
• Notification to security or management

Microsoft describes PIM as a way to provide just-in-time privileged access while reducing excessive, unnecessary or misused permissions. 

The difference is simple:

Without PIM, an administrator may be privileged all day, every day. With PIM, they become privileged only when the task requires it.

Why PIM Matters in a Small Business

A 20-person organisation may have only two or three administrators, but those accounts can still control:

• User accounts
• Password resets
• Authentication methods
• Conditional Access
• Exchange Online
• SharePoint
• Microsoft Teams
• Intune
• Application permissions
• Security settings

If one permanently privileged account is compromised, an attacker may be able to create new users, assign roles, weaken security policies or establish additional access.

PIM reduces the amount of time that high-level permissions are active. It also creates a clearer record of who activated a role, when they activated it and why.

For a small business without a dedicated security operations centre, that reduction in standing access can be more valuable than adding another dashboard that nobody regularly checks.

What Does PIM Cost?

Microsoft currently requires either a Microsoft Entra ID P2 licence or a Microsoft Entra ID Governance licence to use PIM and its full role-management settings. 

The key budgeting point is that you should assess which people actually use the privileged capabilities rather than automatically assuming every employee needs the same licence.

A small company might prioritise suitable licences for:

• Internal Microsoft 365 administrators
• External support engineers using privileged roles
• Employees eligible for administrator access
• Approvers or reviewers where licensing requirements apply
• Users made eligible for privileged group membership

Microsoft’s current licensing guidance should be checked carefully for your exact PIM configuration, particularly when using PIM for Groups, access reviews or mixed Entra licence types. Users eligible for PIM-managed group membership or ownership require an eligible P2 or Entra ID Governance licence. 

Licensing changes over time, so confirm the current Microsoft Product Terms or obtain written licensing advice before purchasing.

Start With the Roles That Matter Most

A small business does not need to move every minor role into PIM on day one.

Begin with roles that could cause major tenant-wide damage, such as:

• Global Administrator
• Privileged Role Administrator
• Conditional Access Administrator
• Authentication Administrator
• Exchange Administrator
• SharePoint Administrator
• Intune Administrator
• Application Administrator
• Cloud Application Administrator
• Security Administrator

Microsoft recommends minimising permanently assigned privileged roles, limiting Global Administrators and using just-in-time access where possible. 

Lower-impact roles can be added later if the process proves useful.

This keeps the initial project small and focuses spending on the accounts that create the greatest risk.

Permanent, Eligible and Active Access

PIM introduces several terms that are important to understand.

Permanent Active Assignment

The user always holds the role.

This is the traditional administrator model and creates standing privilege.

Time-Bound Active Assignment

The user holds the role immediately, but only until a defined date.

This may be appropriate during a migration or temporary project.

Permanent Eligible Assignment

The user may activate the role when needed, but the eligibility itself has no expiry.

This is safer than permanent active access, although the continuing need should still be reviewed.

Time-Bound Eligible Assignment

The user may activate the role only during a defined eligibility period.

This is useful for contractors, temporary cover and project-based administration.

For most routine administrators, eligible rather than permanently active should be the preferred state.

A Budget-Friendly PIM Design

A practical small-business implementation can be remarkably simple.

Global Administrator

Keep permanent active assignments to an absolute minimum.

Normal administrators should be eligible and activate the role only for tasks that genuinely require tenant-wide access.

Suggested controls:

• Phishing-resistant MFA
• Approval required
• Ticket or justification required
• Activation limited to 30–60 minutes
• Immediate activation notification

Maintain separately protected emergency access accounts for tenant recovery. These should not be used for ordinary administration.

Privileged Role and Conditional Access Administrators

These roles can change who has privilege and how users are allowed to sign in.

Suggested controls:

• Eligible assignment
• Approval required
• Short activation period
• Strong authentication
• Notification on activation

Exchange, SharePoint, Teams and Intune Administrators

These roles are important but may be used more frequently.

Suggested controls:

• Eligible assignment
• MFA required
• Justification required
• One- or two-hour activation
• Approval only where business risk justifies the delay

The goal is not to make routine work painful. It is to remove permanent access while keeping legitimate administration practical.

Do Not Require Approval for Everything

Approval can be valuable, but a one-person IT department cannot approve its own emergency request effectively.

Microsoft allows PIM roles to require approval and supports multiple delegated approvers. Approval requests expire if they are not approved within Microsoft’s defined window. 

For a small business, use approval selectively.

Require it for:

• Global Administrator
• Privileged Role Administrator
• Major Conditional Access changes
• High-risk Azure ownership roles
• Sensitive role-assignable groups

For lower-risk operational roles, requiring MFA, a justification and a short activation duration may provide a good balance.

Possible approvers include:

• A second internal administrator
• A company director
• A security lead
• A managed service provider
• A trusted external IT partner

Configure at least two suitable approvers where practical so one unavailable person does not block urgent work.

Use Short but Realistic Activation Periods

An activation should last long enough to complete the task but not the entire working day by default.

Examples:

These are starting points, not universal requirements.

Review how long tasks actually take. If employees constantly reactivate the same role during one job, the period may be too short. If activations regularly remain unused for several hours, it may be too long.

Require a Reason That Means Something

PIM can require users to provide a justification before activation.

Avoid vague entries such as:

• Admin work
• Support
• Needed access
• IT task

A better justification might be:

Service ticket 18427 — Update Conditional Access policy for new finance devices.

Or:

Change request 602 — Configure Exchange transport rule for approved customer workflow.

A clear reason makes audits and incident investigations much easier.

Where possible, require the employee to include the relevant service-ticket or change-reference number.

Configure Notifications

PIM can notify relevant recipients when important events occur, including role assignments and activations. 

For a small organisation, notifications are a low-cost security control.

Send alerts for:

• Global Administrator activation
• Privileged Role Administrator activation
• Permanent role assignments
• Role-setting changes
• Emergency account activity
• Unexpected activation outside working hours

Do not send every routine event to the entire leadership team. Too much noise will cause important alerts to be ignored.

Focus notifications on genuinely powerful roles and unusual behaviour.

Review Eligibility Regularly

PIM prevents roles from being permanently active, but an obsolete eligible assignment still creates risk.

Microsoft supports one-time and recurring access reviews for privileged Entra and Azure roles. These reviews help determine whether users still require their assignments. 

A small-business schedule might be:

• Global Administrator eligibility: monthly
• Other highly privileged roles: quarterly
• Routine administrative roles: every six months
• Contractor eligibility: at project completion
• Managed service provider access: quarterly and at contract renewal

Ask:

• Does the person still perform this responsibility?
• Have they activated the role recently?
• Could a narrower role replace it?
• Should the eligibility have an expiry date?
• Is the external support relationship still active?

An eligible role that has not been used in a year may no longer be necessary.

Consider PIM for Groups

PIM for Groups allows membership or ownership of selected groups to become eligible and time-limited.

This can be useful when group membership grants:

• Administrative roles
• Access to sensitive applications
• Access to confidential SharePoint sites
• Azure permissions
• Security-tool privileges

Microsoft recommends an approval process for eligible group membership when the group is used to elevate users into Entra roles. 

However, small businesses should not introduce PIM for Groups simply because the feature exists.

Start with Entra administrator roles. Add privileged-group management only where it solves a real access problem and the licensing cost is justified.

Keep Emergency Access Outside the Normal Workflow

PIM should not become the only route into the tenant.

Maintain emergency access accounts that can be used if:

• PIM is unavailable
• Approvers cannot be reached
• MFA infrastructure has failed
• A Conditional Access mistake blocks administrators
• The normal administrative identities are compromised

Emergency access credentials should be securely stored, monitored and tested.

They should never be used to avoid waiting for approval or to perform routine maintenance.

Any emergency account sign-in should trigger immediate investigation.

A Low-Cost Rollout Plan

Phase 1: Inventory

List all active and eligible administrator assignments.

Identify:

• Global Administrators
• Privileged roles
• External administrators
• Group-based role assignments
• Applications with privileged access

Phase 2: Reduce

Remove obsolete roles and replace Global Administrator with narrower alternatives wherever possible.

There is little value in placing unnecessary privileges behind PIM when the better answer is to remove them.

Phase 3: Pilot

Choose one or two administrators and move a small set of important roles into eligible assignments.

Test:

• Activation
• MFA
• Approval
• Notifications
• Expiry
• Emergency access

Phase 4: Expand

Move remaining high-risk roles into PIM.

Apply approval only where justified and choose activation periods that match real work.

Phase 5: Review

Schedule regular reviews of active and eligible assignments.

Track:

• Activation frequency
• Rejected requests
• Unused eligibility
• Emergency account activity
• Repeatedly extended activations
• Roles that remain permanently active

Common PIM Mistakes

Buying Licences Without Reducing Roles

PIM controls privilege, but it does not decide whether the user should have the role in the first place.

Remove unnecessary assignments before paying to govern them.

Making Every Activation Require Director Approval

Routine support slows down, and people look for permanent-role exceptions.

Leaving Global Administrator Permanently Active

The organisation purchases PIM but leaves its highest-risk accounts unchanged.

Giving Activations Eight-Hour Durations

The role is temporary in name but effectively permanent for the whole working day.

Ignoring Eligible Assignments

Eligibility should be reviewed just as carefully as active access.

Forgetting External IT Providers

Consultants and support partners may retain privileged eligibility after their work ends.

Failing to Test Emergency Access

The first test occurs during an actual lockout.

Small-Business PIM Checklist

• Confirm current Entra P2 or Entra ID Governance licensing.
• Inventory every privileged role.
• Minimise Global Administrator assignments.
• Replace broad roles with task-specific alternatives.
• Convert suitable active roles into eligible assignments.
• Require strong MFA for activation.
• Use approval for the highest-risk roles.
• Require meaningful justification or ticket references.
• Keep activation periods short.
• Configure high-value notifications.
• Review eligibility regularly.
• Protect and test emergency access accounts.
• Include external administrators and privileged groups.

Final Thoughts

Privileged Identity Management does not have to become a large enterprise project.

For a small business, the greatest value comes from applying it to a handful of powerful roles:

• Global Administrator
• Privileged Role Administrator
• Conditional Access Administrator
• Authentication Administrator
• Key Microsoft 365 service administrators

Begin by removing access that nobody needs. Then use PIM to make the remaining privilege eligible, temporary and visible.

Do not overcomplicate approvals. Do not buy licences for features you have no plan to operate. Focus on the people and roles capable of causing the most damage.

The objective is simple:

Administrators should receive powerful access only when they need it—and lose it automatically when the task is finished.

That is a realistic security improvement even for a small company with a limited budget and a very small IT team.
