"We started working with Citadelo in 2015. They opened up broad horizons in the field of cybersecurity for us, and we showed them the hidden corners of industrial automation. Since then, we have successfully collaborated on several joint projects, including auditing our devices, which are mostly based on proprietary solutions. The Citadelo team helped us identify a number of specific measures that, even in the often tight conditions of industrial automation, allowed us to elevate the cybersecurity of our products to a new level. Citadelo also taught us to think in a slightly different way than before."
