The roots of TreeSolution

TreeSolution Consulting GmbH was founded as a spin-off of the international institute of management in technology (iimt) of the University of Freiburg in Europe.

During his research work there, Dr. Thomas Schlienger specialised in information security culture and awareness. Close interaction with the information security culture working group of the ISSS (Information Security Society Switzerland) and practical experience have always been at the forefront of his activities .

He developed a scientifically sound and practice-oriented perspective on information security in companies, which has been used by numerous companies since 2005. With its TWISK® Security Awareness Radar tool, e-learning offerings, security awareness campaigns and consulting services, TreeSolution, a partner for information security, offers an all-round approach for lasting success.

TreeSolution: Information security right up to the top

Organigrams are typical tools for mapping corporate structures. They are mostly graphs, in which responsibilities are shown in a company from top to bottom.

However, the first modern organization chart, designed in 1854 by McCallum, was designed as a tree from the bottom up. Responsibility for action was assigned to the branches and leaves, as they were closer to the information and thus to the action.

Similarly, security awareness and security culture in companies can only gain a solid base if they are firmly anchored at all levels. This works best when a company understands its security structure as a natural tree and imbues its corporate culture at all levels with an awareness of information security: from roots to trunks in every branch and every leaf.
