OpenBSD is not just a kernel hackers' operating system. Several corporations, universities, and ISP's are using OpenBSD to serve their IT, research and security needs. The following list and associated statistics should speak for themselves about the reliability and integrity of an OpenBSD system.

NOTE: Some companies for security purposes have asked that we do not disclose the name of their business. To comply with these wishes you may notice "Undisclosed Company" in some of our listings.

• Secure Networks, Inc. has been using OpenBSD as their core development platform for their flagship product, Ballista. According to a corporate representative, "it [OpenBSD] has proven to be very stable, and quite well supported for a free operating system." In addition, it should be noted that code from the Ballista project developed on OpenBSD systems was easily ported to Irix and Solaris.
• The University of Minnesota uses OpenBSD on Sun Sparc workstations for network monitoring and capacity planning. They query 32,000 different interfaces via SNMP, logging SNMP data to concatenated disk for processing each month.
• MacMurray College of Jacksonville, Illinois is using a P5/150 as its main server for over 600 students and 100 staff and faculty users. This system is also planned to be used by the MacMurray Computer Science department for both the instrcution of programming and administration. By using OpenBSD on existing hardware, MacMurray plans to save the thousands needed to keep a current version of AIX running on their RS/6000 server.
• RTMX, Inc., produces an OpenBSD derived, IEEE POSIX real time extended system solution. RTMX fully re-implemented previously developed in-house IEEE POSIX realtime extensions using OpenBSD as a root source tree. Nearly all of the IEEE POSIX extensions have been added. Currently all OpenBSD features are supported, but only a reasonable subset of the cpu types & platforms are currently working.
  RTMX is also a licensed OSF Motif house, and has ported Motif 1.2.3 to most of the supported platforms. Yong Chen's VXP Motif GUI Builder has been licensed for porting to OpenBSD/RTMX systems. In addition, RTMX plans to release a general purpose data base package in the not-too-distant future.
  RTMX "believes strongly in the OpenBSD approach...and looks forward to supporting the organization as it grows."
• Poppe Tyson Europe is using OpenBSD as a primary DNS, mailserver for 100+ mailboxes, and as their Website Development server for over 50 sites.
• Felix Schröter is developing a generic IP tunneling program which will be able to tunnel IP and other protocols (OS dependant), through a streams based connections. The software can optionally encrypt and integrity check the packets it transfers. This software is aimed as a solution for VPN (virtual private networks).
  Felix is using OpenBSD because of the pseudo-device "tun" which makes getting IP and other protocol's packets from the kernel quite easily.
  Licensing negotiations for this product are still underway. Felix hopes to provide a free license (binary and source) for non-commericial use.
• TAL Wireless Networks, Inc. uses OpenBSD as a platform for multiple firewall, http proxy and dialup and servers across California. Some of these machines were formerly running the commercial version of BSD, BSD/OS. TALNET S.A., the Argentina based offices of TALNET are using OpenBSD as a mail server, firewall and http proxy.
• Emerging Technologies Inc. makes T1 and other synchronous communications hardware and software for the OpenBSD platform. This hardware is in use in many ISPs world-wide and shows how effectively OpenBSD can be used as a communications routing platform for IP routing. These products allow OpenBSD-based machines to directly connect ot 56kbs DDS, T1 lines or frame relay networks, eliminating the need for an external router.
  On the software end, ET/BWMGR, ET's Bandwith Manager, a part of their software drivers, has been ported to the OpenBSD platform. The bandwith manager can effectively be used as a solution for network managers who need to tune bandwith usage, control the bandwith of their client sites, and clear up network bottlenecks.
• An undisclosed company is using OpenBSD on a Sparc 1+ as a private firewall and WWW server for 50-100 internal client workstations.
• CITI labs at the University of Michigan uses OpenBSD as the basis for many intensive research projects. In the smart card project, OpenBSD is used for analysing the contents and protocols of a given mag-stripe card, both in isolation and in real applications. Plans are underway to issue cards to allow logins and to store PGP keys. OpenBSD is also used as a test platform for the mobile AFS program at CITI. Internally "The Packet Vault" is an OpenBSD machine that captures and records on cd-rom every packet on the local 10 Mbps ethernet. Packet contents are encrypted to comply with privacy requirements. This practice is used for intrusion detection. In addition, a number of people within the department are using OpenBSD as their primary operating system.
