Ncrack High-speed Network Authentication(Crack)
Ncrack tools is a high-speed network authentication cracking. It was built to help companies secure their networks proactively test all their hosts and network devices for poor passwords. Security professionals also rely on Ncrack when checking their customers.

It allows fast but reliable large-scale review of multiple hosts.
Ncrack Features include highly flexible user interface for the granting of a full user control of the network, which allows a very sophisticated attack bruteforcing, patterns of time for ease of use, similar to Nmap run-time interaction and much more.
