GeoServer, an open-source tool unique from ArcGIS.

What are the best aspects of this product?

Free software that enables me to develop and configure stuff according to my preferences.

What aspects are problematic or could work better?

Data protection and technical support are the 2 missing elements. ArcGIS Server provides all these at a reasonable price.

What specific problems in your company were solved by this product?

I'm using this in my attempt to develop a web-based mapping software where users can import images and do GIS evaluation. Every user should have a unique ID and pass. Data protection security is necessary for this.
