How to Perform Effective User Access Reviews (Step-by-Step Guide)

As organizations adopt more SaaS applications, cloud platforms, and remote work environments, managing user access has become increasingly complex.

Employees need access to multiple systems to perform their jobs efficiently. However, without proper oversight, permissions can quickly spiral out of control. Accounts remain active after employees leave, users accumulate privileges as they change roles, and sensitive systems become accessible to far more people than intended. This creates significant security risks.

Unauthorized access, insider threats, and compromised credentials are among the most common causes of data breaches today. This is why user access reviews are a critical component of modern security programs. They help organizations ensure that the right individuals have access to the right systems, no more and no less.

In this blog, we’ll explore:

What user access reviews are
Why they are important for security and compliance
How to perform them effectively
Best practices for building a scalable review process
A solution which can automate and simplify access governance across your organization.

What Is a User Access Review?

A User Access Review (UAR) is a structured process used to verify that users have appropriate access permissions to systems, applications, and data.

During a review, organizations evaluate:

Which users have access to specific systems
What permissions they hold
Whether that access is still required
Whether any permissions should be revoked or modified

User access reviews typically cover:

Employees
Contractors
Third-party vendors
Service accounts
Privileged administrators

The primary objective is to ensure that access aligns with job responsibilities and security policies. Without periodic reviews, organizations often experience privilege creep, where users gradually accumulate unnecessary permissions over time.

Why User Access Reviews Are Important

User access reviews play a critical role in maintaining a strong security posture. Here are some of the most important benefits.

Prevent Privilege Creep

Privilege creep occurs when employees accumulate additional permissions as they move between roles or projects. Over time, users may retain access to systems they no longer need. This creates unnecessary security exposure. Regular access reviews identify and remove outdated permissions before they become a problem.

Reduce Insider Threat Risk

Not all security incidents originate from external attackers. Insider threats can arise from:

Misconfigured permissions
Employee mistakes
Compromised credentials
Malicious insiders

User access reviews help organizations identify risky or excessive access privileges early.

Enforce the Principle of Least Privilege

The principle of least privilege states that users should only have the minimum permissions necessary to perform their job duties. Access reviews help enforce this principle by ensuring that unnecessary permissions are removed and sensitive systems remain tightly controlled.

Support Security and Compliance Frameworks

Many regulatory and compliance frameworks require organizations to regularly review system access. Examples include:

SOC 2
ISO 27001
HIPAA
PCI DSS
NIST 800-53
CMMC
GDPR

Demonstrating that access reviews occur regularly helps organizations maintain compliance and pass security audits.

Reduce Unused Accounts and Licensing Costs

Access reviews also help organizations identify inactive accounts or unnecessary software licenses. Removing unused accounts improves both security and operational efficiency.

How to Perform Effective User Access Reviews

An effective user access review process follows a structured and repeatable workflow. Below are the key steps security teams should follow.

1. Define the Scope of the Review

Start by identifying which systems and users should be reviewed. Focus first on high-risk environments such as:

Cloud infrastructure platforms
Financial systems
Customer data platforms
Administrative accounts

Prioritizing high-impact systems ensures that the most critical risks are addressed first.

2. Gather User Access Data

Next, compile a list of users and permissions across the selected systems. This may involve collecting data from:

Identity providers (Okta, Azure AD, Google Workspace)
SaaS platforms
Databases
Internal applications

Manually collecting this information can be time-consuming and error-prone.

Platforms like Akitra’s User Access Reviews automate this process by aggregating access data from connected systems and presenting it in a centralized dashboard.

3. Identify Inactive or Former Users

One of the most critical checks is ensuring that former employees or contractors no longer have access. Security teams should verify that:

Terminated employees are fully deprovisioned
Contractor accounts are disabled after project completion
Temporary accounts are removed

Inactive accounts are frequently exploited by attackers.

4. Review Role-Based Permissions

Evaluate whether users’ permissions align with their current roles. Ask questions such as:

Does the user still need this level of access?
Has the user recently changed roles?
Are the permissions excessive for their responsibilities?

Adjust permissions accordingly.

5. Review Privileged Accounts

Privileged accounts require special attention because they can modify systems and access sensitive data.

Examples include:

Administrator accounts
Root users
Database administrators
Service accounts with elevated permissions

These accounts should be reviewed frequently, often quarterly or even monthly.

6. Revoke Unnecessary Access

Once inappropriate permissions are identified, they should be removed or modified. Possible actions include:

Removing unused permissions
Downgrading admin privileges
Converting permanent access to temporary access

All changes should be documented.

7. Document and Approve the Review

Finally, document the entire review process. Organizations should record:

Which systems were reviewed
Who approved the review
What access changes were made
Any security risks identified

Maintaining this documentation is essential for audit readiness and compliance reporting.

Best Practices for User Access Reviews

To ensure long-term success, organizations should follow several best practices.

Automate Access Review Workflows

Manual reviews can be difficult to manage at scale. Automation helps organizations:

Aggregate permissions across systems
Trigger review workflows
Send approval requests to managers
Generate audit-ready reports

Automation reduces administrative burden while improving accuracy.

Involve System Owners and Managers

IT teams may not always know whether access is truly required. Managers and system owners should participate in access reviews to ensure permissions reflect real business needs.

Review Privileged Access More Frequently

Privileged accounts present the highest risk. These accounts should be reviewed more frequently than standard user permissions.

Integrate Reviews With Identity Lifecycle Management

User access governance should be integrated with:

Employee onboarding
Role changes
Contractor onboarding
Employee offboarding

This ensures access permissions remain aligned with organizational changes.
