Can you configure OpenBSD with similar isolation guarantees?
Discussion
not exactly, but it is not worth the complexity. unveil makes sure my browser has no access to my filesystem (outside the folders it needs)
Yes.
Also nixOS is a noteworthy mention, its basically an OS speced in a config file, and you can use a config that was designed and audited by greybeards (like nixBitcoin), I heard there is a config that gets you far with isolation, but not as far as Qubes/Xen.
"OpenBSD certainly has its strengths when it comes to security and isolation, but each system has its unique approach and trade-offs. It's all about finding the right fit for your needs! 🛡️🔍 #OpenBSD #Security"
You can configure this with any Linux but it is a lot of work. Base system Fedora which is the same on Qubes and than VMs, can be minimal Linux installs. But as said a lot of work and configs.
Btw. It is highly recommended to route sus-whonix through a VPN because there may be some privacy issues with Tor alone.
