A word from the founder

As a systems and network engineer by training, I founded ADHCI with a simple idea: to give organizations the means to retain full control over their data and tools, without compromising on features or performance.

This means sovereign hosting, the use of open-source technologies, clear explanations of every option and its implications, as well as long-term support.

With my team, we place proximity and reliability at the heart of our approach: listening to your needs, implementing pragmatic solutions, and continuously improving your services. If you are looking for a demanding, transparent, and committed partner, let’s talk.

Our Values

Advanced security and sovereign hosting

Data encryption in transit and at rest, network and application firewalls, hardened systems, and environment isolation, all within a GDPR-compliant framework built on sovereign infrastructure.

Ethical and sustainable commitment

Eco-responsibility, transparency, and respect for privacy guide every decision, with servers hosted in low-impact data centers (PUE 1.26, CUE 0.16 kg CO₂e/kWh IT, WUE 0.37 L/kWh IT).

Availability and reliability

Continuous monitoring and supervision, regular backups, multi-level redundancy, and proactive interventions ensure optimal uptime and uninterrupted service in all circumstances.

High-level technical expertise

Years of experience in systems and networks, combined with deep mastery of cutting-edge technologies, to design, deploy, and optimize complex solutions.

Innovation and open-source technologies

We anticipate your needs with tailor-made solutions based on best practices and the latest open-source advancements, ensuring transparency and independence.

Our Story

Our mission is to design reliable, scalable digital environments where every organization maintains control over its data and tools. More than a service provider, we strive to be a committed partner, able to support your projects in the long term with clarity and high standards.
