Who we are

Welcome to ITENOS! We are an independent IT service provider affiliated with the Deutsche Telekom AG group. When it comes to ICT, we are a highly competent and reliable partner – especially for SMEs.

But let’s start at the beginning: it all started with 12 creative minds who set out to change the IT world. A small start-up, headquartered in Bonn, Germany, and in their briefcases a sophisticated portfolio of virtual data networks and high-quality premises for network nodes and data centers – all tailor-made and highly customized. ITENOS was born. That was in 1993. Since then, a lot has happened: ten years later, the team has already increased tenfold. Today, the ITENOS family has grown to around 220 employees, almost 20 times the manpower. We are growing continuously and developing our expertise, our portfolio and our workforce all the time. This is one of the main reasons why ITENOS has grown into a serious player in the industry, has established itself as a reliable IT and telecommunications company and is now one of the top ICT employers in Germany.

As an IT service provider and telecoms expert we continue to plan, implement and operate individual custom solutions for data centers and IT infrastructure, connectivity, access control and in the area of managed services. Of course, this is all based on state-of-the-art technologies from selected business partners and our own network infrastructures and data centers at different locations throughout Germany – whether in Frankfurt am Main, Düsseldorf, Hamburg, Hamburg or Stuttgart. And we never deviate from the high standards of data protection and security that Germany is known for. In fact, ITENOS relies to a 100 percent on ISO-certified processes – both in matters of IT and cloud security, and in our quality and IT service management. als auch hinsichtlich unseres Qualitäts- und IT-Service-Managements.

But it’s not only our high quality standards that make us special, but above all, our proximity to the customer as well as the ITENOS Factor. We listen closely: what do our customers need? What requirements do they have? What issues and challenges are they dealing with? These are our starting points to seek the right solution – resourceful, fast and reliable. We’re not satisfied with standard answers, are you? No? Then look no further.

History

1992

A project community consisting of eight pioneers set itself the goal of founding a company, which was to develop and manage tailored, virtual data networks based on Datex-P, to provide locations for the network infrastructure of businesses, and to offer the best service possible.

1993

The International Telecom Network Operation Services, or I.T.E.N.OS. GmbH for short, is officially entered into the German commercial register on the 16th of November 1993. The three founding parties are the partners DETECON GmbH, T.D.T. GmbH and GRICON GmbH.

1996/97

After successfully entering its market, ITENOS GmbH’s staff already grows substantially during its first years, to 27 employees. DETECON takes over as sole shareholder.

2000

ITENOS becomes a full subsidiary of T-Data and therefore a member of the Deutsche Telekom AG group. In addition to data networks, equipment housing, carrier network and interconnect, ITENOS expands its portfolio, among other areas, with business SMS solutions as well as telematics including facility management and access solutions.

2003

After ten years in the market, ITENOS’ workforce had already increased tenfold, to 120 employees, documenting a healthy growth, as do the numerous field offices in the German cities of Münster, Berlin, Hamburg, Magdeburg, Frankfurt, Trier and Erlangen.

2007/2008

Under the leadership of Paul Hülsmann and Friedrich-Rainer Bierwirth, ITENOS further expands its business areas: Now, its customers can also rely on ITENOS’ expertise in the areas of housing services, hosting services, connect services and telematics.

2013

Bernd Mitternacht and Siegfried Pleiner become the managing directors of the by now 165 employee-strong company. To keep up with the changes in the market, ITENOS’ portfolio is consolidated into the areas of cloud services, housing, and networks.

2016

A new differentiation towards the areas of data centers (connectivity, colocation and housing in Germany), managed IT services (planning, development and operation of hybrid managed hosting and IaaS solutions), and networks (IP network solutions for businesses with a branch structure) already mirrors the structure of ITENOS’ business units today.

2018

For its 25th anniversary, ITENOS can be proud to have established itself as a renowned institution in the IT and telecommunications sector. Around 220 employees comprise the team one of the best ICT employers in Germany, where they continue to further develop its portfolio.
