Some of you may know or even work with Kali. The pentest (hack) Linux distribution. But do you know Parrot?
It offers many tools designed for web and computer systems analysis, including a lab dedicated to forensic digital use
Parrot is based on Debian's testing branch, with a custom hardened linux 4.8 kernel. It follows a rolling release development model. The desktop environment is MATE, and the default display manager is LightDM.
Personally I think Kali is the better toolkit for pentesting. But when it comes for having a toolkit for (general)security tasks Parrot is a very nice distro.
