About us

Your IT partner from Neckargemünd and Düsseldorf

Since 2002, we have supported businesses with managed IT, hosting and cloud - with our own support team in Neckargemünd and our own infrastructure in the ISO 27001 certified data center in Düsseldorf.

Our locations

Two locations. One team.

Where we feel at home

Our two locations are in two of Germany’s strongest economic regions: Rhine-Neckar and Rhine-Ruhr.

Neckargemünd near Heidelberg

Head office · Support & consulting

From our head office in the Rhine-Neckar metropolitan region, we support small and mid-sized businesses personally - from day-to-day IT support and Microsoft 365 to cloud migration. Short distances, dedicated contacts and quick on-site help when needed.

Düsseldorf

Data center · Infrastructure & operations

In the Düsseldorf data center, we run our own infrastructure - ISO 27001 certified and connected to DE-CIX. Our on-site team ensures the reliable operation of servers, network and managed services.

A LOOK BACK

Our history - from the beginnings to today

Founded in 2002 as a start-up near Heidelberg, oneCorp has grown into an IT service provider for managed IT, hosting and cloud - with its own infrastructure in the Düsseldorf data center. In 2022, we became a GmbH: another milestone that stands for long-term growth, stability and trust - for our customers, our partners and our team.

TECHNICAL EXCELLENCE

Our own infrastructure in Germany - reliable, secure and professionally operated

Today, many providers simply resell external cloud resources. We deliberately take a different approach: as an IT and hosting partner with our own infrastructure in Germany, we give businesses direct control, high availability and dedicated contacts. In the ISO 27001 certified data center in Düsseldorf, we operate more than 1,000 active systems in our own dedicated space - from enterprise servers and backbone routers to switches for business IT, hosting and managed services.

Your benefits as a business

Your own hardware

We operate and manage our systems ourselves - for greater control and reliability.

Secure infrastructure in Germany

Your data and systems run in a secure data center environment in Germany - operated securely and in compliance with data protection regulations.

Dedicated contacts

Bei Fragen oder Störungen sprechen Sie direkt mit erfahrenen Technikern statt mit einem anonymen Callcenter.

OUR APPROACH

Our philosophy: straight talk, not tech jargon

Good IT should not only work reliably, it should noticeably take work off your plate every day. That is why we rely on clear, understandable communication instead of needlessly complicated jargon.
‍
As an IT partner for businesses, we are big enough for complex IT environments and close enough to know our customers personally.

"We make IT understandable. Whether management or IT department - we communicate clearly, directly and on equal footing. That is how we create IT solutions that are technically convincing and genuinely move your business forward."

HOW WE WORK

The oneCorp culture

At oneCorp, we don’t believe in off-the-shelf IT, but in infrastructure that has to be understood in order to be mastered. Since our founding, we have combined the personal proximity of a regional IT company with the capabilities of a specialized hosting provider.

Collaboration on equal terms

Flat hierarchies, short paths and direct communication: that is how we make decisions quickly - within the team and with our customers.

Transparency and open communication

Many things can be resolved more easily and quickly when they take the direct route. We are open about important decisions and developments. We speak plainly!

Passion

We share one motto: “We love what we do!” Every team member contributes to our success - we support and inspire each other.
