OpenBSD

What is OpenBSD?

OpenBSD is a free, UNIX-like operating system based on the 4.4BSD platform, developed by a dedicated community of volunteers. It is renowned for its emphasis on security, correctness, and standardization. OpenBSD has made a name for itself by having only two known remote security holes in the default install over many years. Its integrated cryptography and proactive security philosophy make it a popular choice for security-conscious users.

The operating system originated from the development of OpenSSH, one of the most widely used SSH implementations, which also comes from the OpenBSD project. The current version is OpenBSD 7.8, released on October 22, 2025, marking the 59th release in the project's long history. OpenBSD is available on various platforms and can be freely downloaded from the project's download sites.

The Organization Behind OpenBSD

OpenBSD is not developed by a traditional commercial company. Instead, it is maintained by a community of volunteers spread across the globe. These dedicated developers work on continually improving the operating system by contributing their time and expertise.

The OpenBSD Foundation, a non-profit organization, financially supports the project. It collects donations to fund development and organize developer events. This ensures that OpenBSD remains a free and vibrant operating system that meets the highest standards of security and reliability.
