Your need is legitimate—trust the experts
Many professions linked to public service share a common foundation: professional confidentiality. Some people hold public positions that allow them to access confidential information, defence secrets, as well as security or financial data. The leak of this information could prove catastrophic.
Breaches of the duty of professional confidentiality are a scourge for local authorities. A necessary reminder must be given to staff bound by professional confidentiality of the importance of maintaining the confidentiality of their status, their role and professional information.
For a local authority, an institution, an administration or an organisation where professional confidentiality is essential, calling on a detective agency such as Groupe Hyperion is an effective way to identify indiscreet staff members.
Ensuring compliance with the duty of professional confidentiality is not straightforward; it is sometimes necessary to bring in a service provider, both to train staff on this duty, its implications and the legitimate differences that may exist with professional secrecy, but also to identify indiscreet staff members and those selling confidential and sensitive information.
Groupe Hyperion aims to play a central role in this process. In this way, we offer you a free initial appointment to discuss your situation and provide you with the most appropriate support.
Services provided by Groupe Hyperion
Cyber intelligence
Cyber intelligence makes it possible to monitor online activity and digital communications to detect signs of breaches of the duty of professional confidentiality.
Physical surveillance
Physical surveillance is essential to observe and document the actions of a person suspected of breaching the duty of confidentiality. Our detectives discreetly follow the suspect to identify non-professional meetings where confidential information could be disclosed.
Tailing
Tailing, an extension of surveillance, involves following the suspect more closely and continuously to gather detailed evidence of their actions. This technique is particularly useful for tracking the suspect’s movements to places where confidential information could be shared, such as meetings with competitors or journalists.
Controlled purchase
A “controlled purchase” involves simulating a transaction or commercial interaction to obtain evidence of breaches of the duty of confidentiality. For example, one of our detectives may pose as a client or potential business partner and engage the suspect in conversation to see whether confidential information is disclosed.
