Query: Nocturnal Gnome

This is a good product for those of you who possess a reasonably good understanding of networking. If you don't, do not buy this product! Customer Service is outsourced from India (I've never had a good experience with any of it, expecially the struggle to understand and communicate with agents). First hand knowledge is extremely limited and they rely on databases driven support.
