Parrot Security

This is one of the most popular operating systems for anonymity, and for good reason.

The OS positions itself as an OS for hackers, security specialists, developers, and so on. One of its main advantages is that it has more than 600 preloaded tools that may be useful to you. It has encrypted, secure tools for communication, pentesting, web browsing and everything in between.

It is simple enough for the average user to use, but advanced enough for the most experienced hackers. Personally, I like his forensic tools!

More importantly, he even launched a “web version" recently! You heard right. Now you can access and use the virtual distribution without installing it through a web browser!

Its compatibility is another of its main functions. Parrot Security can probably run on it, even if you have a World War II computer.

It has built-in virtualization tools that allow you to create a virtual hacking lab without endangering your machine. Basically, it's an isolated environment that allows you to play.
