The story
The company was founded in 1977 under the name Deutsche Telepost Consulting as an affiliated entity of Deutsche Bundespost in Bonn, with a focus on providing consulting services to the international telecommunications industry.
Its current structure dates back to 1 August 2002, when a merger with Diebold Deutschland GmbH created the present-day Detecon International GmbH. Diebold itself had been founded in 1954 by John Diebold in New York City and established a presence in Germany in 1959. Ownership of Diebold Deutschland later transferred to debis Systemhaus GmbH, a subsidiary of Daimler-Benz AG, in 1991.
Following Deutsche Telekom’s acquisition of debis Systemhaus in 2002 and its integration into T-Systems, Diebold was subsequently merged with Detecon as part of a broader corporate restructuring.
