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
