Security for the Internet of Things

Always one step ahead

The Internet of Things is a new technology paradigm consisting of a global network of machines and devices with the ability to interact with each other. Due to the significant increases in efficiency, increasing business areas are becoming dependent on the technology. This dependency makes IoT applications a lucrative target for attackers, which is why security issues need to be considered from the start.


We, PHYSEC GmbH, are a young deep-tech company from Bochum. As a spin-off of the renowned Horst Görtz Institute for IT Security (HGI) in Bochum, we look at IoT security holistically from the perspective of research, regulatory authorities and industry. We develop key technologies necessary for the full development of the powerful potential of the new technology paradigm.

About us

Innovative and performance-oriented

Our largest business area is the economically efficient and secure digitalisation of infrastructures in the energy and water industries. We not only offer our customers state-of-the-art transmission technologies, we also offer solutions for their safe use in regulated areas. In contrast to the widespread standard solutions, compliance with the relevant industry standards and the requirements of the GDPR, the BSI and ENISA is not a problem with PHYSEC. This makes us the right partner for municipal utilities when it comes to the secure digitalisation of supply networks.
