OpenBSD
Known for its robust security, OpenBSD is a FREE, multi-platform UNIX-like operating system based on 4.4BSD. With only two remote holes in the default install over an extended period, it emphasizes proactive security, integrated cryptography, and correctness. OpenSSH, a widely used software, originates from this volunteer-driven project.
