I am not satisfied with Linux’s security and have been researching alternative open source OS for privacy and security So far only thing that’s ready to use is GrapheneOS (Based on Android) but that’s not available on desktop (Though when Android release Desktop mode it may become viable)

Qubes OS is wrapper around underlying operating systems, so it doesn’t really fix for example Linux’s security holes it just kinda sandbox/virtualize them

OpenBSD is more secure than Linux on a base level but lack mitigations and patches that are added to linux overtime and it’s security practices while good for it’s time is outdated now

RedoxOS (Written in Rust) got some nice ideas but sticks to same outdated practices and doesn’t break the wheel too much, and security doesn’t seems to be main focus of OS

Haiku and Serenity are outright worse than Linux, especially Haiku as it’s single user only

Serenity adopted Pledge and Unveil from OpenBSD but otherwise lacks basic security features

All new security paradigms seems to be happening in microkernels and these are the ones that caught my eyes

None of these are ready to be used as daily driver OS but in future (hopefully) it may change

Genode seems to be far ahead of game than everything else

Ironclad Written in ADA

Atmosphere And Mesosphere Open Source Re-implementation of Nintendo Switch’s Horizon OS, I didn’t expected this to be security-oriented but seems like Nintendo has done a very solid job

Then there are Managarm, HelenOS, Theseus but I couldn’t figure out how secure they are

Finally there is Kicksecure from creators of Whonix, Kicksecure is a linux distro that plans to fix Linux’s security problems

if you know of any other OS please share it here

      hardened_malloc is a replacement for the libc function malloc. It is not part of Linux.

      MTE is hardware-based, and is in fact restricted to Pixels currently (8+) AFAIK.

      As I said in my first comment to you, do more research.

          They are not buzzwords. I do agree that the project and its members could improve in many ways, but this is unfortunately true for many security focused projects.

              You also made incorrect claims, bordering on lies honestly, as you didn’t seem to be familiar with hardened_malloc and MTE at all, and then doubled-down and called them buzzwords and then deflected in this very comment by claiming you meant “the ultimate result is not much more than buzzwords”. Then you proceeded to personally insult them.

              Your behavior is much less extreme but not so different to the kind of behavior you’re criticizing. But at least Daniel Micay and his “minions” are working very hard to enhance the security and user experience of their users, even if you believe their efforts amount to minor improvements at best. So why should I trust you over them?
