Is Parrot OS as secure as Tails?
Tails is running from USB, loading to RAM so it means that it doesn't use local computer storage. After each start, Tails starts a new session and doesn't store files you had in previous sessions. It means that you can browse using flash drive where installed Tails on someone's computer, but he won't see anything of it because Tails worked in RAM, it erases each shut down.
Parrot OS is an operating system for pentesting, which has hacking and anonymity tools. You can use it from USB too: install .iso file into flash drive, and start it as "Live CD". After restart data was in that session won't appear.
Can you use Parrot OS live mode instead of Tails, will it be as private, or
Does Tails have another security and privacy features except routing all traffic through Tor?
