KALKAN

An operating system built from scratch. There is a lot we do not tell.

From the kernel to the desktop, from the file system to the programming languages, every layer is our own engineering. Nothing was copied, we depend on nothing. And our most distinctive capabilities we we deliberately leave unexplained on this page.

Why KALKAN

Not an operating system,
a security approach.

There is one thing that sets KALKAN apart: every layer, from the very beginning, was designed on a security assumption. Not bolted on later; a foundation laid that way.

01 — FROM SCRATCH

No dependencies

No foreign kernel, no foreign shell, no foreign format. Everything is our own design; that is why we know every layer in depth and can shape it however you want.

02 — SECURITY

Single Door Principle

Every request passing through the system goes through a single security bridge. There is no bypass; nothing unverified runs.

03 — HOLISTIC

One-piece experience

The kernel, the desktop, the applications and the development tools all came from the same team. The parts know each other; there are no surprise incompatibilities.
