Three reasons why some customers choose open source systems as their server platform, or to support high-impact services like e-mail and web serving:
- Reliability
- Security
- Performance
Like all high-performance systems, open source systems require expert support. With Castellan that expertise is only a phone call away. A few of the systems and services we support include
• FreeBSD and OpenBSD;
• Linux, including the popular RedHat distribution;
• Sendmail, Qmail, and Postfix;
• Apache web server;
• File sharing for Windows systems (SAMBA);
• Firewalls, proxies, and IPSec VPNs;
• Network intrusion detection systems;
• Shell scripting for specialized applications
