From NetWitness Corporation:
NetWitness Investigator is the award-winning interactive threat analysis application of the NetWitness NextGen product suite. Investigator provides security operations staff, auditors, and fraud and forensics investigators the power to perform unprecedented free-form contextual analysis of raw network data captured and reconstructed by the NetWitness NextGen infrastructure. Developed originally for the U.S. Intelligence Community, and now used extensively by Law Enforcement, Defense, and other public and private organizations, Investigator is based upon 10 years of development and deployment in some of the most demanding and complex threat environments. With its groundbreaking user interface and unprecedented analytics, Investigator lets you see your network traffic in a new way. Unlike packet analysis products, products which display network traffic in the context of confusing network nomenclature, Investigator uses a lexicon of nouns, verbs and adjectives--characteristics of the actual application and logic layer protocols parsed during session reconstruction.
