Nuix Desktop is the main product provided by Nuix. It is capable of processing many different forensic image formats including EnCase, AccessData and raw dd images.
Processing the data produces a full text index that can be quickly searched. It has the ability to extract out several types of "named entities" including email addresses, IP addresses, references to companies and currencies. It also provides a network graph to see the communications detected inside the data.
There is also a "light weight" version of Nuix Desktop called Proof Finder.
