Technology that works in everyday use
ONNA GmbH, based in Cologne, brings companies into the cloud securely and gets more out of the cloud they already use. We also deliver and install network, telephony, security technology and hardware – with our own shop. We work pragmatically, reliably and vendor-neutrally.

What defines us
Cloud and on-site technology
Cloud consulting, operations, network, telephony and hardware work together at ONNA – you deal with one contact.
Reliable
Keeping promises, meeting deadlines and communicating openly when something doesn't go to plan.
Pragmatic
We use what works and is economical – our own development where it adds value, standard products where they fit.
Close to you
We look at workflows and sites before we recommend anything, and we stay available after handover.

Our commitment as the ONNA GmbH teamWe build technology that works in everyday use – and we stay reachable once it is in operation.
How we work
Every project starts with a conversation about goals, workflows and constraints. Only then do we talk about technology. This is how solutions emerge that fit your business and prove themselves in operation.
We work in manageable stages with clear results. You see early on where things are heading and can adjust priorities before effort is spent.
What we stand for
For us, the cloud and on-site technology belong together. The best cloud is of little use if network, telephony or workplaces cannot keep up – so we plan both together and avoid isolated solutions.
- Transparent quotes and traceable recommendations
- Vendor-neutral advice: Azure, AWS, Google Cloud or European providers
- Documented, maintainable solutions instead of lock-in
- One contact from enquiry to operation
