Our Products

With innovative security and connectivity concepts, PHYSEC enables the successful implementation of new functionalities and business models in the Internet of Things. Here, the secure digitization of products, processes and production ensuring data integrity and security are the key to success. Our PHYSEC products offer long-term concepts with strong security and comprehensive self-determination of your data.

IoTree™ is our solution for cost efficient and secure digitization of your products. Your customers can rely on highest security standards - developed according to BSI and NSA standards. IoTree™ includes key authentication, strong cryptography, authentication and management of keys and identities. The interlinking of serial production and the IT department, gets easier, without making compromises concerning future IT security standards.

IoTree™ offers cost-efficiency and minimizes the risk in production through decentralized key establishment. Thus, IoTree™ does not create new complexities and dependencies.

GuardianPi is a wireless intrusion detection system that protects you against attacks against your wireless network (such as WLAN, LoRa, and Smart Home systems). For this purpose, independently acting sensors (GuardianPis) are set up in your area and report detected attacks immediately to a central server. The alerts are available in realtime and you can react immediately.

KRITIS-Box represents our modern VPN solution which convinces with the following advantages compared to commercially available products. The decentralized architecture of this VPN solution makes expensive configuration and administration unnecessary. Our solution offers a user-friendly installation and usage which requires no deep technical knowledge. Furthermore our technology offers post-quantum resistance by using state-of-the-art cryptographic primitives. Post-quantum technology is essential for long-term use.

Our Technology Demonstrator for channel information evaluation provides our industrial and academic partners the opportunity to gain knowledge of the research area of Physical-Layer Security. Potential applications are secure generation and provisioning of secret cryptographic keys (Channel Reciprocity based Key Generation, CRKG) and physical prevention of relay attacks (Channel Reciprocity based Relay Detection, CRRD).

On June 23, eco - Verband der Internetwirtschaft e.V. honored outstanding companies working in the field of IoT with their eco Internet Award for the 16th time. The jury distinguished innovative solutions, which will be essential in areas such as mobility, entertainment, security and infrastructure.

The motto of the gala was "Gala für Vordenker", where eco CEO Prof. Michael Rotert welcomed over 400 exclusive guests, including numerous managing directors and internet pioneers. He emphasized: Above average, many pioneers are found in the internet economy. New products and services rise from their ideas that turn the world upside down at a breathtaking pace. Some can follow this pace easier, others can not, especially in politics.

Jury: „Die Lösung von PHYSEC leistet einen wichtigen und innovativen Beitrag zum Schutz vernetzter digitaler Dinge des betrieblichen sowie privaten Alltags.“

The origin of PHYSEC is the Horst Görtz Institute for IT Security (HGI) in Bochum. The HGI is one of the world's leading research institutes in the field of IT security with about twenty professors and the largest Bachelor / Master program in Europe. The research and promotion results of Christian Zenger at the chair of Embedded Security which is held by Prof. Christof Paar, motivated our successful approach for the EXIST research transfer of the BMWi and enabled us developing our products based on the PHYSEC technology. Here, digital self-determination of our customers through successful implementation of digital business models with highest IT security requirements is the central motivation for our work.

Our Awards

As well the PHYSEC technology, as the products and business models, based on it, have been awarded several times and confirmed us to follow our way.

The foundational idea based on the PHYSEC technology was presented at the Chair for Embedded Security at the Ruhr-UniversitÀt Bochum in context of the research project PROPHYLAXE supported by the BMBF. This was a cooperation with BOSCH, ESCRYPT, Frauenhofer HHI, TU Dresden, TU Kaiserslautern and the chair Digital Communication Systems at the RUB. The research task in this consortium was to attack systems, which are based on the new physical layer security technology. Meanwhile, further innovative methods have been developed for this basic technology. This developments were the basics for future individual customer solutions. We are working on a wide range of research projects to optimize the PHYSEC technology and we are permanently looking for new fields of applications for our technology. Beneath the individual keydistribution for every device there are the Post-Quantum-Resistance, the protection against relay attacks and the integrity protection, which are interesting research topics for PHYSEC technology.


As an innovative company, PHYSEC is permanently looking for motivated employees. We offer a dynamic work environment with exciting challenges in the rapidly growing market of IT security and digitization. We are looking forward to receive initiative applications from the fields of software development, embedded implementations, security concepts, business development and sales.
