Founded in 1967 on the Satory plateau in Versailles, Eurosatory is currently the largest international land and air-land defence and security exhibition. Held once every two years, in 2012 the exhibition welcomed over 53,480 professional visitors from 130 countries who came to meet the 1,432 exhibitors from 53 countries, under the keen eye of 684 accredited journalists, from all five continents.

Initially defence dedicated, Eurosatory has gradually opened up to the realm of security as most exhibitors produce systems for both sectors. While the contexts of use differ greatly between defence and security, there is true technological continuum between the products. This can clearly be seen from a review of the techniques used in the two fields: unmanned vehicles, surveillance cameras, all-terrain vehicles, communication means, flak jackets, emergency medicine in crisis situations, etc.
