I know in penetration testing world, tools are not important that much. But as a geek, I usually search for new linux
distros, hacking tools and so on. I'm a fan of kali linux, as you know it's based on debian and it comes with a huge
amount of tools that we ever need and both of these features are great.
But in some cases we cannot (or we don't want to) use kali linux. for example I'm working in IT department(as an IT
expert). Because kali is so famous my manager can easily detect it in network or he can see my monitor when i want to
log in to my kali linux. Of course that we can make kali more undetectable (and it was only an example) but it's a good idea to
have an alternative for kali linux for these cases. Parrot security OS can be a good alternative, parrot is developed by
Frozenbox Network and designed to perform security and penetration tests, do forensic analysis or be anonymous on the web.
Parrot Security uses a the Mate Desktop environment which is a nice change of pace. This is a Debian-based distribution similar
in look and feel to Kali Linux because the crew at Frozen Network started with the Kali git repository
