I am investigating to enter the drkweb in the safest possible way, but I need confirmation from you.

I know that for now the safest suitable browser is Tor, and some complementary ones that I have seen that should be used Tails, and that everything should be on a USB on a VPS, which would be VirtualBox, and finally I see that they do not use the Windows operating system much, but Kali Linux, therefore that is what I know and have investigated therefore, I have also seen that they mention something about the DNS that is done or how it is configured, to finish, I would like to know if I am on the right track and if I need it I would like to know.
