Started playing with the freely available VMs from FireEye. Seems like nice Windows based alternatives to Kali and Parrot OS for at least basic pentesting and forensics tools. Personally I like Kali for its sustainability in the market, frequent updates and tools arsenal. However Parrot has grown on me with its sleek design.
Anyways, it seems FireEye got a lot from acquiring Mandiant a while ago. The Redline toolkit is quite nice, so it will be interesting to see how these two plays out:
Commando VM is for penetration testing, see Github.
Flare VM is for malware analysis.
