Industrial Espionage Detective in France
Your strategic information is highly sought after
Patents, customer files, pricing information, research projects, business strategy: a company’s information assets are often its most valuable—and therefore most coveted—assets. Leaks orchestrated by an employee, the theft of know-how by a competitor, an internal mole, or indiscretions during sensitive meetings: there are many forms of industrial espionage, and their consequences can be significant.
When confidential information falls into the wrong hands, the company must identify the source of the leak and gather evidence, while securing its communications for the future. This requires two types of expertise: investigative skills to trace the individuals responsible, and technical expertise to detect any potential eavesdropping or interception devices.
It is essential to act quickly: as long as the leak continues, the damage worsens with each passing day. A methodical response makes it possible to understand how the information is circulating, to stop its spread, and to compile a usable case file.
What Our Services Include
Our goal is to identify the source of the leak and secure your information:
Investigate the source of the leak and identify the individuals involved;
Evidence of the theft of know-how or files;
Identification of any potential links to a competitor;
Cross-checking with the internal information you provide to us;
Dated and documented findings that can be used in court.
When the leak involves technical means, we deploy our technical surveillance countermeasures (TSCM) to search your premises for bugs, transmitters, or other listening devices and secure your sensitive areas.
How is the procedure performed?
It all starts with a confidential, free, and no-obligation consultation to assess the situation and define a clear objective. We provide you with a step-by-step plan and a detailed estimate. Our investigators then proceed with the utmost discretion, anywhere in France, combining investigative work with technical expertise when necessary. You’ll receive a detailed report designed to support legal proceedings and be used by your attorney.

Secure Your Sensitive Information for the Long Term
Identifying the source of a leak is not enough—you must also prevent it from happening again. Beyond simply identifying the issue, we help you understand the vulnerabilities—whether human or technical—that made the leak possible. This analysis enables you to strengthen your practices and better protect your information assets in the future.
The report we are submitting is prepared to be admissible in court, which gives you the option to choose how to respond: a claim for damages, a complaint, or internal measures. In any case, you have a solid case file to help you make an informed decision.
Combined Investigation and Technical Detection
The strength of our approach lies in the integration of two complementary areas of expertise. Investigative work focuses on individuals and networks; technical surveillance secures the premises and uncovers any surveillance devices. Bringing these two areas of expertise together within the same team ensures a cohesive response, without fragmentation or loss of information among the various parties involved.
This complementary nature is particularly valuable in espionage cases, where the source of a leak is rarely obvious and may involve a combination of human and technical factors.

Understanding the Gap to Bridge It
An information leak is never a matter of chance: it exploits a vulnerability, whether human or technical. Identifying the perpetrator is necessary, but understanding how the information spread is just as important, because it is this understanding that makes it possible to prevent the next leak. We therefore trace the path the information took to give you the tools to address the problem at its root.
This analysis leads to concrete recommendations: reviewing access controls, raising awareness, securing sensitive data exchanges, and conducting technical audits of facilities. You don’t just walk away from the assessment with an identified culprit, but with an organization that is better equipped to protect its information assets.
Prompt service and absolute confidentiality
In these strategic matters, two requirements take precedence. First, responsiveness, because as long as the leak continues, each passing day exacerbates the damage and facilitates the spread of information. Second, confidentiality, because any carelessness would alert the perpetrator, who would then cover their tracks and adjust their behavior.
Our teams therefore act quickly and with the utmost discretion, coordinating with only a very limited number of contacts within your company. These two requirements guide every decision we make, from the initial observation through to the delivery of the report.
Bringing together investigative and technical detection efforts within a single team further enhances this efficiency: no information is lost between team members, and the response remains fully consistent across both the human and technical aspects.
When it comes to such strategic issues, the first instinct is often the right one: as soon as a series of clues raises concerns about a leak, it’s better to bring in professionals than to attempt an internal investigation that could alert the perpetrator. A swift and controlled response minimizes damage, preserves evidence, and keeps you in control. We’re here to support you in handling this situation with the rigor and confidentiality that the circumstances demand.
