About us

Who are we?

G-TAC Software was founded by Carsten Schaefer. We are a small team of software developers distributed over various countries.
We work in a loosely coupled team and try to build products that delight our customers.

Why did we start?

Since 1996, I have worked for some of the largest German companies as a highly paid Windows consultant.

I did a lot of consolidation and migration projects in Windows enterprise environments. As part of these, I created tons of tools in various languages that helped me do my job.

These tools helped me analyze file systems and allowed me to easily merge or rework folder structures. One of the hardest problems was to retrieve all trustees of a given folder. This is why I wrote a tool for getting the security rights of folders and analyzing the nested Active Directory groups. This tool generated lists of users and their respective permissions — an ideal foundation for my work.

During that time, I realized that many Windows environments have huge security problems.

Thus, I've developed FolderSecurityViewer to help administrators analyze their file systems. With our easy-to-use tool, even data owners such as project or department leaders can get insights into all the permissions associated with their data.
