Transparency Guaranteed.

Mutual trust and acceptance: we are fully aware of our obligations and responsibilities to society and the environment. Transparency is much more to us than a mere buzzword and we act accordingly. We have our processes, facilities and systems audited regularly by independent parties to ensure that we are operating safely. Our Integrated Management System is certified according to the international standards ISO 9001, ISO 14001 and ISO 45001 or will be in conformity with ISO 27001 and ISO 27019 according to the IT security catalogue.

Accordingly we also demand the most of our suppliers, partners and service vendors. Who these are and which guiding principles we follow are documented and available here.
