Security as religion — forked from NetBSD over a mailing-list fight; gave the world OpenSSH, pf, and the audit-everything method.

Descended from NetBSD
Created by Theo de Raadt
Predecessors BSD NetBSD

Theo de Raadt forked NetBSD in 1995 over commit access and built OpenBSD — the security-obsessed fork that audits code proactively, invented OpenSSH, PF, OpenBGPD, and the 'only two remote holes in the default install' brag.\n\nEvery security-first claim in modern OS marketing descends from OpenBSD's practices.
