The Ligue Internationale des Sociétés de Surveillance was founded in 1934. The registered offices are based in Berne, Switzerland. The Ligue is an association of private security organisations throughout the free world.
Over the years it has played a vital role in defining, establishing and maintaining the highest ethical and professional standards of the private security industry as we know it world-wide.
This has been achieved through the very open and cordial exchange of ideas and experiences between the member companies, who are all leading companies in the countries they represent.
The Ligue is now represented on all continents and in thirty four countries.
As a mark of the high esteem in which the Ligue is held world-wide it is represented in a consultative capacity as a non-governmental organisation at the United Nations and the European Common Market.
