Quick and Simple Setup

Get Going in 3 Steps: Choose directories to audit, tweak settings if you want (or stick with the defaults), and hit ‘Audit’. It’s that easy to start scanning folder permissions.

One-Time Install: No fuss setup. Install once and you’re good to go—no extra configurations needed.

Powerful and Efficient Auditing

Speed and Precision: Fast scans deliver detailed insights into folder permissions accurately, helping you secure your data.

Flexible Filters: Customize audits with versatile filters. Whether it’s by department, job title, or access type, get exactly the info you need. Plus, our advanced caching speeds up the process, outperforming similar tools.

In-Depth Insights and Control

Comprehensive Visibility: The account view shows you everything - which users and groups have what rights in each directory.

Detailed Filters for Any Scenario: Whether during or after audits, use a wide array of filters (from basic to advanced permissions, account details, and more) to pinpoint specific data, enhancing security and compliance effortlessly.

Key features


You can export audit results to a range of file formats including Excel (XLSX), CSV, XML, HTML and PDF. Exports can be performed in two ways – folder view export (categorized by folders) and principal view export (categorized by accounts).

Folder tree view

Hierarchical folder view providing all folder details such as path, owner, permissions, etc.

Account view

See all users, groups and computers, and all directories to which they have access.

Account data

See the main information about the account – display name, security identifier (SID), description and additional data such as department, manager, job title, etc. For group accounts, you can display information about direct and nested group members.

Powerful and diverse filters

The filter manager offers a wide range of options to filter audit results and can be applied in two ways – audit time filtering and post audit filtering, which enables you to filter data and change filter conditions without needing to redo the audit.

Exclude directories and accounts

Exclude unnecessary directories by specifying the exact path or just the directory name. You can also exclude system directories and reparse points from your audit results, limit audit depth by specifying directory depth limit and exclude disabled accounts and specific accounts from audit results.

Data storage

All data can be stored in the local, secure database. No additional setup is needed – it’s all included in the installation. You can access historical audit data at any time.

Don’t overload Your system

Fast and efficient, it uses RAM and CPU efficiently to generate results as quickly as possible without overloading PC resources. It uses various caching mechanisms to reduce Active Directory request counts to the minimum.

Change reports

You can compare two audit results and see what has changed. Change reports will show you which directories, directory permissions and group members have been removed, added or modified.
