The OpenBSD distribution is recognized by security experts as the most secure operating system in the world.
The system is not easy to install, especially with regard to the disk partitioning.
The development team of OpenBSD is financed through donations and the sale gadgets such as posters and t-shirts, especially from the sale of official CDs produced about every 6 months.
To encourage users to buy the official CDs, ISO images are not made available to the network.
