The GSIS will take place on 9–10 December 2026 at the CCH – Congress Center Hamburg and is jointly organised by Hamburg Messe und Congress and the International Institute for Strategic Studies (IISS). Positioned at the intersection of security, technological innovation and economic resilience, the Summit brings together international leaders from government, industry, the armed forces, technology companies and academia to discuss the future of global security architectures.
Specialist Media Perspectives Enrich the Dialogue
Through its partnership with Tamm Media, GSIS is adding a valuable editorial perspective to its communications. Mittler Report Verlag is a well-established publishing house covering defence, security and technology policy, reaching key decision-makers across government, the armed forces, industry and academia. The partnership will strengthen the visibility of GSIS's core themes—including digital technologies, security-relevant innovation and strategic resilience—and extend their impact beyond the Summit into the international professional discourse. In doing so, it will further highlight how technological developments increasingly shape security policy and economic resilience.
Cross-Media Editorial Coverage
As part of the cooperation, Mittler Report Verlag will integrate GSIS into its established editorial formats across print and digital channels. The objective is to ensure that the Summit's key themes reach specialist audiences through multiple communication platforms.
"Technology is becoming a defining factor for security and resilience. GSIS makes these interdependencies visible—and together with Mittler Report we are bringing them into the international professional debate," says Dimitrios Argirakos, Executive Chair of GSIS.
"GSIS brings together the people shaping Europe's future security and innovation capabilities. As Germany's leading specialist media company for defence and security, we provide the visibility, reach and connectivity that foster dialogue, long-term partnerships and concrete projects," adds Peter Tamm, Publisher of Mittler Report Verlag and CEO of Tamm Media.
Through this partnership, the topics addressed at GSIS will gain even greater visibility within relevant specialist discussions.
