In Lyon, many requests start from something very simple: a conversation that was not supposed to get out… and yet it does. Sometimes it is a meeting, sometimes an informal exchange, sometimes a home where you no longer feel completely “at home”.
In these situations, the most useful thing is not to multiply hypotheses, but to re-establish a framework: define a perimeter, verify methodically, then reinforce what needs to be reinforced.
Groupe Hypérion operates in Lyon for counter-surveillance (TSCM) assignments: searching for audio/video capture devices (bug, hidden camera, recorder) and geolocation devices (tracker), in offices, homes and vehicles, with a premium approach: discretion, rigour, recommendations.
