The Fraunhofer Center for the Security of Socio-Technical Systems (Fraunhofer SIRIOS) makes complex security scenarios tangible and controllable in order to increase security and resilience in society.

Public safety faces major challenges, be it climate-induced disaster, industrial accidents, terrorist attacks, or riots at major events. In addition, the interdependencies between people, technology and infrastructure make public safety and security complex and difficult to manage. Therefore, the scope of their impact dependents on a multitude of direct or indirect influences, and existing security solutions often cover only partial aspects. Disruptions within such socio-technical systems can have severe and wide-scale effects, for example on the supply of electricity, internet, telecommunications, water and logistics. In order to research and simulate these interdependencies and deal with the effects of disruptions, Fraunhofer SIRIOS, which was founded in 2021 in Berlin, combines the expertise of the Fraunhofer institutes EMI, FOKUS, IOSB and IVI.

With funding from the German federal government and the state of Berlin during its first five years, Fraunhofer SIRIOS builds a research, testing and training environment for coupled simulations of complex security scenarios that is unique in Europe. Located at the Berlin Fraunhofer FOKUS, a growing number of employees is going to research and work collaboratively on cross-institute projects to build up the center.

Simulation – Transfer – Impact

Interconnected simulations and new models: Modelling the development and impact of complex socio-technical threats or disruptions and deriving scientifically sound measures.

Transfer to the authorities for safety and security: Putting solutions for the interaction of technology, infrastructure, emergency forces and population in complex situations into practice, working together with stakeholders.

Impact on security and resilience: Supporting the assessment and controllability of new technologies in the event of an emergency, ensuring the protection of data and personal rights, and increaseing citizens' subjective sense of security.

Fraunhofer SIRIOS sees itself as an incubator for new public safety and security technologies. Its research focuses on digital building and infrastructure twins, secure supply networks and infrastructures, collaborative responder systems, virtual situation visualization, and efficiency of communication and response in crisis situations. In different scenarios, relevant parameters and interdependencies of modern society are identified and exemplified in coupled simulations. The evaluations reveal existing vulnerabilities and create room for new protection and resilience strategies.

The center focuses particularly on transferring the research into practice: Working with network partners in safety and security authorities, industry, research and politics, new models of technical systems and human behavior are integrated into complex scenarios, tested in simulations and evaluated within the transfer network. At the same time, regular exchange formats ensure that the needs which arise in practice are channeled back into research. Thus, Fraunhofer SIRIOS fulfills an important function in integrating legal frameworks, working methods of authorities and organizations, procedures in research and development, business models of technology companies as well as the acceptance of the population “by design”, i.e. from the very beginning, into the scientific development process. The center understands scenario-oriented simulations as a technology-open and cross-departmental methodology for all stakeholders involved.

Technologies have to prove themselves in real-life situations. As a result, Fraunhofer SIRIOS network partners are going to receive comprehensive support that no other scientific or commercial simulation platform currently offers: A collaborative environment for training and simulation with virtual missions in two- or three-dimensional space as well as an open architecture for stress testing commercial and non-commercial models and systems to evaluate vulnerabilities and technical-organizational synergies.


As a neutral platform, Fraunhofer SIRIOS assumes an important function in bringing together the interests and requirements of the stakeholders for technology development: legal frameworks, working methods of authorities and organizations, approaches in research and development, business models, and the acceptance of citizens.
