Our Services



If you have Linux infrastructure or are considering one, we can help you throughout its life cycle. From initial design to proof of concept and production deployment. Once you're up and running we can continue to monitor, maintain and patch on an ongoing basis.

We can also provide audit capabilities to review and document the security and resiliency of your environment.

If you lack resiliency we can work with you to add redundancy or reduce your hardware dependency by implementing virtualisation.



24x7 Host and service monitoring with SMS alerting paired with historical graphing for capacity planning and trend analysis is the best way to ensure your kit is running and running at it's best.

Utilising Nagios, the worlds best and most powerful open source monitoring platform, and Cacti, a mature and flexible open source graphing engine, we can provide alerting and instrumentation either from our in-house platform, or we can build you a customised solution.

Either paging to your staff or to ours, knowing about a problem early reduces downtime and helps diagnose the root cause.
