DeliverPoint 2007 is now available for FREE with a full production license for a limited number of features. In this free version you'll enjoy the following features in your SharePoint Server 2007 deployment:
- Security Trimmed interface
- Discover Object Permissions
- Properties reporting
- Discover Account Permissions
I would encourage you to use DeliverPoint 2007 in your environment. It is the permissions tool that will help you significantly understand who has permissions to objects and sites with reporting capabilities.
