Hi Bill
GPPT does not change the way GP Task and Role based Security works. However, it does extend the security model with Deny Based Security. Windows and SQL both have the ability to grant and deny security. Standard GP can only grant. GP Power Tools adds the deny ability on a per user per company basis. So you can use Tasks and Roles to grant access and then use Deny based security to fine tune the settings.
If you have two users with the same tasks and roles, you can deny access from a resource for one of those users WITHOUT having to make duplicates of all the tasks and roles and modify the duplicates.
GPPT also provides many tools to help administer security including, Resource Information, Security Profiler, Security Information, Security Information Resources, Security Log and Security Analyzer windows. It is the best tool for working with GP application level Security available.
It has a free 30 day trial period and is very cheap to purchase a subscription at US$500 a year for one module.

I suggest that all partners and customers review the benefits presentation so you can see why every GP customer globally should have GP Power Tools: https://www.winthropdc.com/ftp/pub/GPPowerTools_Benefits.ppsx
You can also watch the demonstration videos at https://winthropdc.wordpress.com/gp-power-tools-portal/gp-power-tools-videos/.
To understand what is in each module look at the following posts:

All sites are going to want the Administrator Tools module. If upgrading, changing server or creating test environments I would suggest that getting the Database Tools module which includes Database Validation which can find and fix many upgrade issues before that cause problems (You should install on the pre upgrade version.). If you want the ability to actively debug, customize GP or write self-help scripts then you should also get the Developer Tools module.
The pricing is on the website, and you can get a quote or place the order using the online form. In summary, the customer pricing for an annual subscription is US$500, US$900, US$1300 (or AU$500, AU$900, AU$1300 plus GST in Australia) for 1, 2 or 3 modules respectively. This is a per system cost and is not affected by the number of users, companies or workstations.
Customers can also just install the code and activate a free 30 day trial period to try out all the features to help you decide on what modules you want.
