Specialists in Unix, Open Source, Disaster Recovery & Enterprise IT Solutions
We deliver expert technology services across Unix/Linux environments, disaster recovery, Open Source projects, and enterprise-grade Internet and Intranet infrastructure. Our team helps organisations build secure, optimised systems for long-term success.
Our name reflects the three pillars of our approach to Information Technology:
We offer deep expertise in system architecture, infrastructure management, and performance optimisation — especially in Unix and Linux environments, enterprise systems, and mission-critical applications.
We create intuitive, secure, and high-performance user experiences that bridge systems, applications, and users with ease.
We specialise in bringing diverse technologies together to work in harmony — improving efficiency, reliability, and ROI across your IT landscape.
We collaborate with clients to develop customised strategies aligned with their business goals and IT needs. Find out more on the Company page.
We actively contribute to and leverage Open Source projects — delivering flexible, cost-effective, and secure solutions. We are involved in projects such as Relax-and-Recover (ReaR), ReaR Automated Testing, ReaR User Guide, Upgrade-UX, Config 2 HTML, and many more. You can browse all contributions on the GitHub page of Gratien D'haese. We use Git for version control across all projects, making it easy to collaborate, experiment with features, and track changes.
Our comprehensive disaster recovery services help protect your operations and data from disruptions, ensuring business continuity. We develop, maintain, and support Relax-and-Recover (ReaR) — the de facto standard bare metal disaster recovery framework on Linux, used by enterprises worldwide including Red Hat and Oracle environments. View our ReaR support contract options.
Our mission is to be the glue between the three IT domains.
Where others stop, we start.
