Industrial espionage is a real threat for any company with significant assets. There are many ways sensitive information can be obtained about your company. Often, internal safety measures are not considered and certain information is literally up for grabs. In addition, an employee may be too loose lipped in circumstances when it might be overheard, or an employee may even be deployed in your company as a spy by a competing company.
As a licensed private investigator, we are able to gather information about people and detect industrial espionage. The latter is even explicitly mentioned in the Act of 19 July 1991 regulating the profession of private investigator.
