The Horst Görtz Institute for IT Security – Interdisciplinary, Innovative & International

The Horst Görtz Institute for IT Security (HGI), Research Department of the Ruhr-Universität Bochum (RUB), is one of the largest and most renowned institutes in the field of IT security in Europe.

More than 160 scientists, 39 of them professors, conduct research at our institute in their working groups within the fields of computer science, electrical engineering and information technology and mathematics as well as the humanities and social sciences. In this interdisciplinary environment, almost all aspects of IT security are covered.

Our success is based on the three pillars Research, Early career and Networking.

Since 2019, the Cluster of Excellence "CASA: Cyber Security in the Age of Large-Scale Adversaries" has been established at the HGI. It is the only German cluster of excellence in the field of IT security. CASA is funded by the German Research Foundation (DFG) with about 30 million Euros. Further information can be found on the CASA homepage.

Several RUB faculties are involved in the HGI, including the Faculty of Computer Science.

The HGI is the European leader in research on IT security and is particularly distinguished by its breadth of expertise. In addition to basic research in the field of cryptology, the HGI also covers the areas of software and hardware security, user-friendliness and other overarching socially relevant topics in its research.

The HGI has produced nine ERC Grantees and has attracted a large number of third-party funded projects, which have led to groundbreaking findings and innovations.

The Ruhr-University Bochum (RUB) pioneered the first German diploma course in IT security back in 2000.

Today, the RUB offers four IT security study programs: a consecutive Bachelor's and Master's program, a Master for students with a Bachelor degree in computer science, electrical engineering, information technology, mathematics or physics and a part-time distance learning program.

Around 1,000 students with 200 matriculations and 120 degrees per year make the RUB the largest educational institution for IT security in Europe.

The HGI is closely networked with leading research institutions for IT security around the world. Close cooperation takes place with the newly founded Max Planck Institute for Security and Privacy. The Ruhr Area is considered a hotspot for IT security in Germany – with the HGI as central nodal point.

Various cooperations and projects are underway with global companies such as Google, Intel, IBM and Bosch.

Numerous successful IT security startups have emerged from the HGI. Since 2018, the HGI startup incubator CUBE5 supports potential founders in the best possible way.
