All our services are certified with the "swiss digital services" seal of approval, as they are 100% Swiss-made. Some products are at least 60% developed in Switzerland and therefore also carry the "swiss made software" label. You will find this seal on the corresponding products.

This symbol stands for high-quality and first-class Swiss ICT products and services. It is only awarded to products and services that have been carefully tested and meet values such as quality, innovation and precision in software development and independence, reliability, and integrity in services.


Dr. Thomas Schlienger

Social responsibility

TreeSolution goes Green!

Thanks to the partnership with Evertreen trees are planted on every continent, reducing CO2 emissions while alleviating poverty. That is why we have chosen this partnership.

The trees are planted directly by local farmers and bring environmental, social and economic benefits. Each tree is certified, can be visited or donated to third parties.

Via satellite surveillance it is possible to follow the trees' growth.

Security awareness and security culture must be firmly embedded in companies for them to gain a foothold. An organization should understand its security structure as a natural tree and imbue its corporate culture at all levels with an awareness of information security: from roots to trunks in every branch and every leaf.

Trees are planted for every new customer. Let's plant a TreeSolution forest together and increase security in your organization!


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.
