Easy and fast

Easy to setup and get started

Get up and running with just one installation – no other configuration is needed.

Fast and accurate

Immediate and accurate insights into NTFS permissions for all target folders.

Versatile filters

The filters incorporate lots of factors – use ‘And’ and ‘Or’ to manage them and get the information you need. You can even add more factors after you’ve filtered by department, position or manager if necessary.

The account view

This view allows you to see users and groups, and all the rights and directories for each user.

Optimized caching mechanism

To make results faster and more efficient than with similar tools.


Use filters during or after the audit to get the exact information you need:

  • Basic permission
  • Advanced permission
  • Permission access type (Allow/Deny)
  • Permission is inherited
  • Directory inherits permissions
  • Domain name (NetBIOS)
  • Domain SID
  • Group contains no members
  • Permissions are identical to parent directory
  • SID cannot be resolved to account name
  • Apply to
  • Directory full permissions list
  • Account state
  • Account name
  • Account SID
  • Account disabled
  • Folder owner
  • Account manager

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.
