Hyperion Private Detective in France: your questions, our answers
A CNAPS-licensed private detective is a professional investigator authorized to practice by the National Council for Private Security Activities. This license guarantees that the detective has met strict requirements in terms of training, morality, and compliance with the legal framework. In France, hiring an unlicensed detective exposes the client to evidence inadmissible in court and legal risks. All Groupe Hypérion investigators are CNAPS-licensed and operate in strict compliance with legislation.
Groupe Hypérion has agencies in Paris, Montpellier, Lyon, Toulouse, Limoges, and Angers, as well as an international agency in Geneva. Our detectives also operate throughout mainland France and the French Overseas Departments and Territories, traveling quickly according to the needs of each mission. For complex investigations requiring simultaneous investigations in several cities, our national network allows us to coordinate operations without delay.
Yes, provided it has been collected in compliance with the legal framework. Following the evolution of the jurisprudence of the Court of Cassation in 2023, evidence obtained by a private detective is admissible as long as it meets the criteria of indispensability and proportionality. Groupe Hypérion’s reports are drafted according to these requirements and are regularly admitted before labor courts, commercial courts, and judicial courts throughout France.
The cost of an investigation depends on its nature, duration, and complexity. Surveillance of sick leave does not mobilize the same resources as an investigation into unfair competition or a search for a missing person. This is why we systematically provide a transparent and personalized quote before any intervention, without obligation on your part. The first consultation is free and confidential.
A private detective is an independent professional, licensed by the State, who acts on behalf of individuals, businesses, or communities within a civil framework. They collect evidence admissible in court but do not have police powers. A police investigator acts within the criminal framework, upon judicial requisition, with prerogatives that a private detective does not possess. Both can intervene in complementary cases: the detective often provides civil evidence that triggers or strengthens criminal proceedings.
