About us

IIA Switzerland is a professional association for internal auditing in Switzerland and Liechtenstein.

The history of the association

IIA Switzerland has played an important role in the development of companies in Switzerland and Liechtenstein ever since it was founded in 1980. The association supports its members with a wealth of experience and its drive to continue adapting the field of internal auditing in line with ongoing technological and economic developments. Thanks to its close contact with other professional associations around the world, it is able to observe economic and political developments abroad and draw appropriate conclusions for the field of internal auditing early on.
