The Best Free Permission Analyzer Software for IT Admins Managing access rights is a constant challenge for IT administrators. Over-privileged accounts, nested groups, and orphaned permissions create massive security blind spots. Commercial identity and access management (IAM) tools are expensive, but several high-quality free tools can map, audit, and analyze access rights effectively.
Here are the best free permission analyzer software solutions available for IT admins today. 1. CJWDEV NTFS Permissions Reporter (Free Edition)
This tool is a staple for Windows system administrators who need to audit file share security.
Best For: Modern file servers and Network Attached Storage (NAS) devices.
Key Features: It quickly scans directory trees and builds reports on user and group access. The interface mimics standard Windows layouts, making it highly intuitive.
The Catch: The free version restricts filtering options and only exports data to HTML. You must upgrade to the paid version to export to Excel (CSV). 2. Netwrix Effective Permissions Tool
Netwrix offers a specialized, lightweight utility designed to solve the mystery of “effective permissions”—the actual access a user has after combining cumulative group policies and explicit denials.
Best For: Verifying a specific user’s access across Active Directory (AD) and file shares.
Key Features: It provides a clear, actionable view of why a user has access to a specific resource by unpacking nested AD groups.
The Catch: It operates on a per-user or per-object basis. It is not built for bulk, multi-directory scanning. 3. SolarWinds Permissions Analyzer for Active Directory
SolarWinds provides a completely free standalone desktop utility that delivers instant visibility into AD and file permissions.
Best For: Rapid troubleshooting of individual access tickets.
Key Features: Input a user name and a folder path to get a hierarchical breakdown of permissions. It highlights whether access is granted via explicit permissions or group inheritance.
The Catch: Like the Netwrix tool, it is a point-in-time diagnostic tool rather than a comprehensive, automated reporting suite. 4. ManageEngine ADManager Plus (Free Edition)
For administrators looking for a more comprehensive management suite rather than a single utility, ManageEngine offers a restricted free tier. Best For: Small businesses or lab environments.
Key Features: It includes dedicated NTFS and Active Directory permission reporting modules. It allows you to track modified permissions and view security principals cleanly.
The Catch: The free edition is strictly limited to managing a maximum of 100 domain objects. Summary Checklist for Selection
