A strong experience since 1989,
International presence.

ATERMES, a company founded in 1989, is today a group with a staff of almost 200 people.

Through steady growth, ATERMES has developed more and more skills, in its four key areas: Mechanical Engineering, Electronic, Optronics and Software.
With this accumulated experience and our substantial industrial resources behind them, our teams develop high technology solutions for the harshest technical, environmental or climatic conditions.

This has naturally led us to develop our partnership with the defence market, and with industrial markets where the demands are severe.

Since the year 2000, ATERMES has also been developing its own product lines dedicated to tough environmental conditions. In 2012 ATERMES took a major step forward in this activity when it launched its revolutionary mobile border surveillance system, BARIER™.
