The term "users" has several connotations. End users often want to meet other users of the system, to share ideas, problems and solutions, and discuss the system over a meal or a beer. One of the best ways to do this is with one of our User Groups worldwide.

Another connotation of the term is "who is using the system, and for what?", and that is the subject of the rest of this page. These companies and organizations trust OpenBSD's rigorous code audit and security-first development model. They use the system to build firewalls, intrusion detection systems, or general purpose servers. University researchers and IT department developers often have similar security and stability requirements and choose OpenBSD. Many Internet Service Providers find OpenBSD's security features hard to resist. Even governments from different countries pick OpenBSD for securing their vital informational infrastructure.

NOTE: For reasons of security, companies can ask us to withhold their names, or those of their clients. They would then appear as "Undisclosed Company".

One goal of any ISP is to keep their customers' sites and accounts safe from intrusion. OpenBSD's security record speaks for itself, so many ISPs use OpenBSD for this reason alone. However, others use OpenBSD for many, if not most, of their services.
