A rural and heritage department, land of Armagnac and agritourism, Gers experiences situations where discretion and objective evidence are essential to resolve disputes. Groupe Hyperion provides you with a team of CNAPS-approved private investigators, accustomed to operating in the department to defend your rights and secure your interests. Our reports are meticulously drafted and are admissible before civil, labor, or criminal courts, provided that the evidence has been obtained lawfully and with respect for privacy.
Our missions for individuals
We assist individuals with everyday disputes as well as sensitive situations: adultery and divorce, child custody and residence arrangements, alimony and revisions, abuse of vulnerable persons, searches for missing or lost contact persons, and asset searches (property, addresses, solvency). We combine surveillance, shadowing, administrative inquiries, and information gathering to produce objective and actionable evidence.
Our missions for professionals
For businesses, executives, and HR departments, we conduct investigations aimed at protecting activity and assets: control of absences and prolonged sick leave, fraud and internal theft, unfair competition (client diversion, non-compliance with a non-compete clause), employee monitoring (undeclared activity, illicit multiple employment), labor court investigations, and, when the context justifies it, commercial infiltration. Each mission is legally framed, proportionate, and limited to what is strictly necessary.
Areas of intervention
We operate throughout the Gers department, particularly in Auch, L’Isle-Jourdain, Condom, Fleurance, Mirande, Eauze, Lectoure, as well as in other municipalities of the department. Our local network and organization allow us to quickly deploy appropriate resources (teams of two, staggered hours, inter-departmental relays) to ensure continuity of observation and the quality of evidence.
Method and compliance
Each case undergoes a preliminary analysis: evidence objectives, scope of research, legal constraints, and observation strategy. We favor proportionate and traceable methods; reports detail dates, times, locations, and observed facts, supported by material evidence when possible. The entire package is submitted as a structured investigation report, directly usable.
