Overview

The Center for Security Studies (CSS) is a research and policy institution based at the Swiss Federal Institute of Technology in Zurich, commonly known as ETH Zurich. Established in 1986 by Professor Kurt Spillmann, the center examines security policy challenges affecting Switzerland and the wider international system. Its work combines academic research, practitioner training, policy analysis, public communication, and the development of information resources for people working on international relations and security affairs. The center operates at the intersection of scholarship and applied policy. Its research addresses questions surrounding the formulation and implementation of security policy, including the broader political and institutional challenges involved in managing threats to peace and stability. Alongside its academic activities, the CSS includes an independent think-tank function concerned with Swiss and international security policy and with the advancement of peace. This dual orientation allows it to produce research for academic audiences while also engaging government officials, practitioners, journalists, students, and the wider public. A stated role of the CSS is to connect academia, practitioners, and the public on security-related matters. It therefore supports both the production of knowledge and the training of researchers and professionals. Its output has included research studies, policy analysis, scholarly publications, educational material, and open-access information services. The center's activities are international in scope, although Switzerland remains a central reference point for its research and policy work. The CSS is also institutionally connected to the Center for Comparative and International Studies (CIS), a joint academic structure involving ETH Zurich and the University of Zurich. Through this relationship, the security center operates alongside political science expertise and comparative and international studies rather than as a standalone commercial enterprise. Among the projects associated with the CSS are the Parallel History Project, which assembled and analyzed declassified and other governmental records concerning the Cold War, and the International Relations and Security Network (ISN), an online information service that distributed open-access resources on international relations and security. ISN ended operations in 2016. Its extensive digital library and other materials were subsequently incorporated into CSS activities through CSS Resources. This transition preserved and reorganized a substantial body of publicly available research and reference material within the center. Professor Andreas Wenger has led the CSS since 2002, following Spillmann's founding leadership. The center remains an active ETH Zurich research institution with a mission spanning security research, practitioner education, peace-oriented policy work, and public-facing knowledge dissemination.

History

The Center for Security Studies was founded in 1986 at the Swiss Federal Institute of Technology in Zurich by Professor Kurt Spillmann. From its beginning, the institution was designed to study security policy in a manner relevant to both Switzerland and the international community. Rather than limiting itself to a narrow military-security brief, the center developed an interdisciplinary and policy-oriented approach concerned with the challenges involved in developing security policy and responding to threats to peace and stability. Spillmann established the center as an academic institution with an applied public-policy purpose. Its activities included research on security-related issues, the training of researchers and practitioners, and communication between specialists and the broader public. The center also developed an independent think-tank component focused on Swiss and international security policy and on the promotion of peace. This combination of university research and policy engagement became a defining feature of the CSS. The CSS later became associated with the Center for Comparative and International Studies, or CIS. CIS brings together political science professorships at ETH Zurich and the University of Zurich. The connection situated the CSS within a wider institutional environment devoted to comparative politics, international relations, and international studies, while preserving its specialized focus on security. A major strand of the center's work has involved creating and maintaining resources for researchers, officials, practitioners, and the public. The Parallel History Project collected and examined declassified and other government records related to the Cold War. By bringing dispersed documentary sources together, the project supported historical research into international security and the development of strategic and political relations during the Cold War period. The International Relations and Security Network was another important CSS-supported initiative. It operated as an online information service offering open-access products and resources on international relations and security. The service extended the center's public-information role beyond conventional academic publishing by making research and reference material accessible through a dedicated digital platform. ISN closed in 2016. Following its closure, the service's extensive digital library and other products were incorporated into the CSS and transformed into CSS Resources, allowing the center to continue providing organized security-related information. Professor Andreas Wenger assumed leadership of the CSS in 2002 and has led the center since then. Under its continuing ETH Zurich affiliation, the CSS has maintained a broad mission: producing research, supporting education and professional training, contributing to security-policy debates, promoting peace-oriented analysis, and linking academic expertise with practical decision-making. The center's work remains international in outlook while retaining a distinct interest in Swiss security policy and Switzerland's position in international affairs.
