The Skunk switch is a fantastic device with the ability of bypassing NAC silently, it fits both Red Team operation and Penetration tests. Its configuration takes a few steps, allowing you to focus on the real assessment and the actual fun. I highly recommend to add a Skunk switch to your Red Team/Pentest arsenal.
Netsplit is awesome. It fits in your pocket. You don't have to care about power. Plug it and get access to the network and its secrets
Azban opens up new possibilities for exploitation, especially getting an initial foothold, without having to think about keyboard layout or OS. It's pretty amazing :)
