Quebes + Whonix

Here is the explanation why you do not see Debian listed.

I cannot really comment on the others.

Looks like Qubes uses Linux with the blobs. Also, by default Whonix uses Virtualbox, which depends on a non-free compiler since version 4.2. These are things that seem to be wrong at a glance.

Thank you lembas. I wanted to test them, they together looked a very good security solution. But now I see they're not.

I find it interesting you ask about this on the trisquel forums I don't think this is the place... They are based on xen hypervisor, fedora and debian.

but if you use a windows vm obviously thats proprietary. They also are gpl2 not gplv3 for obvious reasons.

It is not as user friendly as trisquel is and is more resource intensive and still depends alot on good user opsec.

Trisquel with grsecurity kernel patch, apparmor, and ufw is pretty good security. hardenubuntu.com has great tips. Feel free to post if you have questions on anything.
