What is an Access Review?

Access review is a periodic process where organizations evaluate and validate user access to systems, applications, and data to ensure it remains appropriate. Access review helps organizations confirm that users only retain access required for their roles. As a result, it reduces the risk of excessive or outdated permissions.

How does the process typically run?

Organizations conduct access reviews at defined intervals or after key events.

Typically:

• Teams identify users and their current access rights
• Managers or system owners review assigned permissions
• Reviewers approve, modify, or revoke access

Additionally, organizations may trigger reviews during role changes or offboarding.

What gets evaluated?

Access reviews focus on validating permissions across systems.

• User access – Reviews all permissions assigned to an individual
• Application access – Evaluates who can access a specific system
• Role-based access – Checks whether roles still align with job functions
• Privileged access – Reviews high-risk or administrative permissions

For example, teams often prioritize privileged accounts due to higher risks.

Why do organizations rely on access review?

Access reviews strengthen governance and improve visibility into access.

They help:

• Maintain least privilege across environments
• Identify unused or excessive permissions
• Support compliance with standards like ISO 27001 and SOX

However, manual reviews can become inconsistent. Therefore, organizations often standardize workflows and automate parts of the process.

Common gaps and risks

Access reviews can lose effectiveness without proper structure.

• Infrequent reviews leave outdated access in place
• Large environments increase review complexity
• Lack of ownership delays decision-making

As a result, organizations must define clear accountability and review cycles.

How Hexnode supports access review?

The identity provider enforces access decisions, while Hexnode adds supporting context through endpoint compliance.

Hexnode provides device posture signals such as encryption status, password compliance, app compliance, and jailbreak or root detection. It shares this compliance data with identity systems to support policy-based access decisions.

Additionally, it provides visibility into endpoint state, helping teams assess whether devices meet security requirements. As a result, organizations can incorporate device compliance into access governance workflows to help reduce risk.

FAQs
