Seccubus automates regular vulnerability scans and provides delta reporting. On 8/1, the project released version 1.5 "The DefCon Edition." This version includes support for controlling Nikto through Seccubus directly, leveraging the NBE report format which Frank Breedijk (Seccubus' author) wrote and released with the 2.1.2 version of Nikto.
In addition to working with Seccubus, Frank's NBE report format should allow for easy Nikto integration into any program which supports Nessus imports.
