Who are we?

Institute for Advanced Studies in National Defence

The Institut des hautes études de défense nationale (IHEDN) is a national public administrative body under the supervision of the Prime Minister and, more specifically, of the Secrétariat général à la défense et à la sécurité nationale (SGDSN).

The Institut des hautes études de défense nationale (IHEDN) prepares leaders from all spheres of activity to assume the highest responsibilities by developing their understanding of national defence and security issues, their knowledge of related public policies, their perception of the interplay of players involved in their implementation, and their aptitude for strategic thinking. The training provided as part of the national session is designed to enable all students to grasp from the outset the cross-sectoral, interdisciplinary, interministerial, European and international dimensions of defence and security issues through a common foundation and in-depth study of 5 major areas (Armament and the Defence Economy, Economic Defence and Security, Maritime Issues and Strategies, Defence Policy, Digital Sovereignty and Cybersecurity).

The IHEDN, working to build and disseminate a common defence culture, helps to forge lasting links between senior public and private, civilian and military officials.
