Vision & Values

    ERNW is, in terms of technology, manufacturers and financing, an independent service provider. Projects, recommendation of measures or the highlighting of optimization potential is never influenced by contracts with certain manufacturers, bias against certain products or claims of external stakeholder.

  • Expertise

    The continued development of our ERNW team’s expertise is our highest value, and one that is fully supported by our company through continued education, research, and shared innovation.

  • Knowledge transfer

    We believe that shared knowledge empowers ourselves as a company, our customers, and the international IT security community in which we actively participate.


Our Mission

This independence and self-accountability drives us, as a company, to adhere to a higher standard of professional conduct and development.
