Located at the gates of Geneva and Lyon, Ain combines industrial, agricultural, and border areas, generating varied investigation needs. Groupe Hyperion provides its CNAPS-licensed private detectives to individuals and businesses. Our missions aim to collect evidence admissible in court, in compliance with the Internal Security Code and privacy laws.
Our assignments for individuals
We assist individuals in sensitive matters: adultery and divorce, child custody and child support, abuse of weakness, searches for missing persons or people lost to sight, asset investigations. Our methods combine tailing, surveillance, and administrative research.
Our assignments for professionals
We help companies and institutions protect their interests: checks on abusive sick leave, fraud and internal theft, unfair competition, employee checks, employment tribunal investigations. All our interventions comply with the legal and ethical framework.
Areas of operation
Our private detectives operate throughout the Ain department, particularly in Bourg-en-Bresse, Oyonnax, Ambérieu-en-Bugey, Bellegarde-sur-Valserine, Gex, Miribel, Ferney-Voltaire, as well as in other communes. Thanks to our network, we quickly deploy appropriate resources.
Method and compliance
Each assignment is subject to a prior analysis: objectives, legal constraints, and strategy. We apply proportionate, traceable, compliant means. Our reports are structured, detailed, and usable before the courts.
