At [http://www.openwall.com Openwall], we develop our own Open Source software with a focus on security, including [http://www.openwall.com/Owl/ Openwall GNU/*/Linux] (or Owl for short), a security-enhanced server platform.

Our [http://www.openwall.com/services/ professional services] include remote installation (you boot off CD, we do the rest) and maintenance (systems and security administration) of OpenVZ-enabled servers and mini-networks of such servers. We typically use the OpenVZ kernel, the Owl userland for the host system, and arbitrary Linux distributions for the containers (most often that's Owl as well - with additional software to meet your needs). We readily have software solutions for provision of advanced LAMP hosting with cross virtual host security separation within each container (that is, not only the containers are separated due to OpenVZ, but also virtual hosts within containers are separated at the OS level), multi-server backups (incremental, remote, encrypted, integrity-checked), monitoring (many custom Nagios sensors, including for things such as backups, filesystem errors, RAID status, etc.), and more.
