In Geneva, confidentiality is not a “nice-to-have”—it is often a working condition. When doubt arises, it does not concern only a place: it concerns trust, exchanges, and the ability to make decisions calmly.
In this context, a TSCM (counter-surveillance) detection is used to do things properly: define a perimeter, verify methodically, then put in place simple, consistent preventive measures.
Groupe Hypérion operates in Geneva and its surrounding area, depending on access and organisational conditions, to search for audio/video capture devices (microphone, hidden camera, recorder) and geolocation devices (tracker), with a premium approach: discretion, rigour, recommendations.
