Why Most Entra ID Access Review Campaigns Fail
Entra ID access reviews are a cornerstone of modern identity governance, intended to ensure that only the right people retain access to critical systems and data. Yet, despite their importance, most access review campaigns in Microsoft Entra ID (formerly Azure AD) fail to deliver real security or audit value. The primary culprit? Reviewer fatigue.
The Reality of Reviewer Fatigue
When reviewers are presented with a sprawling, contextless list of users, groups, and access assignments, the process quickly becomes a mechanical tick-box exercise. Reviewers often lack both the context and the motivation to make informed decisions. As a result, reviews are either left incomplete or performed superficially, undermining both security objectives and audit defensibility.
> Key Point: The success of any Entra ID access review hinges on the reviewer’s ability to make informed, timely decisions. Overloading reviewers is the fastest way to guarantee failure.
Understanding Reviewer Fatigue and Its Impact
Reviewer fatigue is not simply a matter of too many items to review. It is compounded by the lack of context, unclear ownership, and the absence of operational follow-through. When campaigns are poorly scoped, reviewers are left to wade through irrelevant or low-risk items, diverting attention from genuine risks.
Consequences of Reviewer Fatigue:
- Low completion rates: Reviews are abandoned or only partially completed.
- Superficial decisions: Reviewers approve access en masse, often without real scrutiny.
- Audit risk: Incomplete or poorly documented reviews fail to meet audit requirements.
Scoping Effective Access Review Campaigns
The most effective way to combat reviewer fatigue is thoughtful campaign scoping. Rather than reviewing every group or application, focus efforts where they matter most.
Focusing on High-Risk Groups and Privileged Roles
Start by identifying high-risk groups, those with access to sensitive data, critical infrastructure, or elevated privileges. Privileged roles (such as Global Administrator, Privileged Role Administrator, or custom roles with broad permissions) should always be prioritised.
Example Table: High-Risk Groups and Roles
| Group/Role Name | Description | Reason for Priority |
|---|---|---|
| Global Administrators | Full control over Entra ID and resources | High risk of compromise |
| Finance Application Users | Access to financial data | Sensitive business impact |
| Security Operations Team | Access to security tools and logs | Key to incident response |
Selecting Critical Applications for Review
Not all applications are created equal. Focus reviews on applications that:
- Contain sensitive or regulated data (e.g., HR, finance, customer PII)
- Provide privileged access or administrative functions
- Have a history of access sprawl or infrequent review
By narrowing the scope, you reduce reviewer workload and increase the quality of decisions.
Defining ‘Good Enough’ Evidence for Audits
An access review that is completed but leaves no defensible audit trail is of little value. Auditors expect to see not just that a review occurred, but that it was meaningful and traceable.
Required Reviewer Decisions and Timestamps
At a minimum, you should capture:
- Reviewer decisions (approve, deny, remove)
- Timestamps for each decision
- Reviewer identity (who made the decision)
Entra ID natively logs these elements, and they are typically exportable for audit purposes.
Example: Access Review Audit Log Entry
{
"reviewer": "jane.smith@org.co.uk",
"decision": "approve",
"timestamp": "2024-05-09T15:32:00Z",
"item": "Finance Application User",
"justification": "Active in Q2 project, confirmed with manager"
}Adding Business Context to Strengthen Audit Defensibility
While technical evidence is essential, adding business context (such as recent activity, project involvement, or a justification for access) can greatly improve the defensibility of your reviews.
- Justification field: Encourage reviewers to provide a brief reason for retaining or removing access.
- Activity data: Where possible, provide reviewers with information about recent user activity or group participation.
This context transforms reviews from a formality into a meaningful control.
Common Gaps in Native Entra ID Access Review Workflows
Despite its strengths, Entra ID’s native access review workflows have operational gaps that can derail even well-scoped campaigns.
Limited Campaign Visibility and Ownership
Campaign visibility is often restricted to the campaign creator or a small group of admins. Stakeholders and business owners lack real-time insight into campaign progress, making it difficult to drive accountability.
- No central dashboard: Review progress is not easily shared across teams or up to management.
- Unclear ownership: It is often ambiguous who is responsible for chasing incomplete reviews.
Inconsistent Follow-Up and Lack of Escalation
If reviewers ignore their tasks or deadlines, native Entra ID workflows do little to enforce completion.
- No automated escalation: Overdue reviews are not systematically escalated to managers or risk owners.
- Manual chase-up: Admins must manually track and nudge reviewers, which is time-consuming and error-prone.
These gaps result in incomplete campaigns and missed audit deadlines.
How Custodeum Helps Operationalise Entra ID Access Reviews
Custodeum addresses these operational challenges by enhancing visibility, ownership, and follow-through for Entra ID access reviews, without altering the underlying review process or introducing unnecessary complexity.
Improving Campaign Visibility and Ownership
Custodeum provides a clear, centralised view of all ongoing and completed access review campaigns. This visibility extends to:
- Stakeholders: Business owners and risk managers can monitor progress.
- Reviewers: Clear assignment of review ownership and responsibilities.
- Admins: Single pane of glass for campaign health and bottlenecks.
Structured Chase-Up and Escalation of Incomplete Reviews
Custodeum enables structured follow-up for incomplete reviews:
- Automated chase-up: Systematically reminds reviewers of outstanding tasks.
- Escalation workflow: Incomplete reviews can be escalated to managers or risk owners for action.
- Audit-ready logs: All follow-up actions are logged, supporting audit requirements.
> Note: Custodeum does not change the underlying Entra ID review process, it operationalises it, ensuring reviews are completed and audit-ready.
Practical Steps to Design Access Review Campaigns That Get Completed
The following steps will help you design and run Entra ID access review campaigns that are both manageable and defensible.
Grouping and Prioritising Review Items
- Group by risk: Prioritise high-risk groups, privileged roles, and critical applications.
- Batch reviews: Avoid overwhelming reviewers by batching reviews into manageable segments.
- Delegate wisely: Assign reviews to those with the best business context.
Setting Clear Deadlines and Expectations
- Communicate timelines: Set explicit start and end dates for each campaign.
- Reminders: Schedule regular reminders for reviewers.
- Escalation plan: Define what happens if reviews are not completed on time.
Providing Evidence and Context to Reviewers
- Pre-populate context: Where possible, provide recent activity or business justification fields.
- Decision rationale: Require or encourage reviewers to record the reason for each decision.
- Support materials: Offer documentation or guidance on what constitutes appropriate access.
Example: Reviewer Checklist
| Step | Description |
|---|---|
| Review assigned items | Access review portal/email notification |
| Assess business need | Confirm if access is still required |
| Record decision and rationale | Approve/remove and enter justification |
| Submit review | Complete before deadline |
