dScanner is a distributed network security scanner. The driving force behind dScanner is Nessus, the network security scanner located at http://www.nessus.org. dScanner ties Nessus into a distributed system producing a distributed network security scanner.

dScanner was born from a need to analyze the network security posture of a very large network in a timely manner. The traditional approach of using a single scanner would produce results in days. dScanner is projected to deliver results in minutes. Since Nessus is a best of breed contender in its field, it was by obvious choice well suited to mutate into a distributed system.
