The Institute for Security and Defence Analysis (ISDA) is an Athens-based, private, non-profit organization concerned with matters of security and defense, foreign policy and energy and their political, military, financial and industrial aspects.

The ISDA area of interest includes South Eastern Europe, the Middle East and the Persian Gulf Regions. Its true strength lies on its members and associates; it is represented by a balanced mix of renowned academics, authoritative analysts and experienced professionals from the government, the armed forces and the defence industry.

Monitoring related developments on a daily basis, the ISDA predominantly retains a proactive role in the generation and circulation of ideas. It is hoped that these ideas will lead to discussions and debates that will in turn assist the improvement of security and defense related decision making processes, legislation, procurement methods and industrial cooperation.
