CLIP OS has been in development since before 2008.[1][2] In September 2018, ANSSI released two version of CLIP OS to the public: a stable version 4, and an in-development version 5.[2][1]
System overview
CLIP OS is based on the Hardened Gentoo variant of Gentoo Linux.[4] The developers have noted that whilst it has similar aims to Qubes OS, the environment isolation mechanism is different.[3] Further, administrators on a CLIP OS system will not be able to access user data, unlike a Qubes-based system.
