Loire is centred around Saint-Étienne, Roanne and Firminy, combining industrial heritage with economic renewal. Groupe Hyperion provides individuals and businesses with its CNAPS-licensed private detectives. Our assignments aim to gather 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 contact, asset investigations. Our methods combine surveillance, monitoring and administrative research.
Our assignments for professionals
We help businesses 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 Loire department, notably in Saint-Étienne, Roanne, Saint-Chamond, Firminy, Montbrison, Rive-de-Gier, Andrézieux-Bouthéon, as well as in other municipalities. Thanks to our network, we can quickly deploy the appropriate resources.
Method and compliance
Each assignment is subject to a preliminary analysis: objectives, legal constraints and strategy. We apply proportionate, traceable and compliant measures. Our reports are structured, detailed and usable before the courts.
