We've all done it a few times. Lost that nmap scan, can't recall what file had that accout and password combination, sat in front of a screen for a few days while your co-worker gathered tons of data and didn't share because he's a big fat jerk.
Kvasir is a centralized, pentration tester-focused data homoginizing application to help collect, unify and make sense of the important data gathered during tests. It's a small footprint application designed for quick deployment. It integrates directly with NeXpose and Metasploit (for now).
This application is used daily by Cisco Systems engineers on customer penetration tests. It hasn't solved the big fat jerk problem but it has helped us work better as a team.
