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.

• CORE SDI S.A. an Information Security company based in Buenos Aires, Argentina uses OpenBSD as the main platform for operation and development of information security related products. "The robustness, portability and commitment to security of OpenBSD, as well as the ability to run on different hardware platforms, provides an ideal operating system for environments where security and high availability are major concerns" , says Ivan Arce, CORE SDI's CEO.
• 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.
• Empire Net, an ISP in Bend, Oregon, uses OpenBSD on Sun Sparc and Intel Pentium Pro machines for network monitoring, routing (including wireless and DSL connections), web site hosting, NFS, and anything else that needs to be both fast and secure..
• 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 instruction 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-commercial 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.
• An undisclosed company is using OpenBSD on a Sparc 1+ as a private firewall and WWW server for 50-100 internal client workstations.
• The Center for Information Technology Integration (CITI) at the University of Michigan uses OpenBSD as the basis for many intensive research projects. OpenBSD is used for developing and analyzing smart card contents and protocols, both in isolation and in real applications. Plans are underway to issue cards containing secure tokens for user logins and kerberos ticket acquisition. OpenBSD is also used as a test platform for the mobile computing 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.
• The University of Alberta uses OpenBSD on SPARC and Intel hardware for proxy servers in front of labs and student residences, Kerberos servers, and web based course services using WebCT.

webFreaks.com, LLC is a new startup company of 3 employess in Silicon Valley. Our shell account server currently has 300-400 users running on AMD and Cyrix CPUs connected to the internet via 384K ADSL (there are 2 locations in Mountain View and Cupertino, CA, each connected with ADSL). We also custom design webpages and banner ads.
