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.

  We run as servers currently two OpenBSD, one Solaris and two Linux boxes. With OpenBSD we handle the main web site (happily running on a 7-year old Sparcstation 5), part of our mail accounts and our firewall.
  There are two additional OpenBSD computers, in our development area. One of them acts as a network monitor (using Snort) and will shortly be moved to sit next to the firewall, and the other one serves as an OpenBSD CVS mirror.
  We do not do run very creative stuff, we just use OpenBSD for what it does best: run smoothly, even on older hardware, freeing us from most concerns and doubts we have about our other operating systems.
  We also host a Spanish OpenBSD mailing list (openbsd@tlali.iztacala.unam.mx).

  "OpenBSD needed some tuning on these machines, especially bigger maxprocs and maxfiles, but it handles extraordinary loads on ordinary hardware. We are using AMD Athlons (mostly the new Thunderbirds) and AMD K6-III's. We also have some internal machines running OpenBSD as testbeds and printservers and all sorts of other purposes. We plan to move some more machines to OpenBSD, especially our firewalls. Unfortunately we are still running some closed source software, but we'd like to try the Linux emulation. OpenBSD's behaviour under high load, especially under DoS attacks, just doesn't compare to the Linux we used before - Linux went extremely slow, while OpenBSD doesn't even care (same hardware!)".
