Hidden “Ears” in Walls, Floors and Devices

Eavesdropping devices – commonly referred to as “bugs” – can be concealed almost anywhere in the smallest housings, e.g. in light fixtures, smoke detectors, skirting boards, gaps between floorboards and similar places. Unnoticed, they record everything spoken inside the compromised rooms; this allows your internal business information to leak outside and usually straight into the hands of competitors. As the business owner, you suspect nothing and are left puzzled by the consequences: copied products, altered behaviour from business contacts (keyword: defamation), intensified price battles, more difficult client acquisition. Losses caused by industrial espionage are often immense – in many cases even existentially threatening.

At the slightest suspicion that internal information could be accessible to unauthorised persons or might become so, swift action is paramount. Our Swiss eavesdropping specialists are highly equipped experts in detecting audio surveillance devices. They inspect every square centimetre of potentially compromised premises and also check vehicles and mobile objects. A detailed inspection of the inventory (furniture, devices, decorative items and more) is naturally part of any room sweep. Counter-surveillance and bug detection require extensive technical effort and exceptional expertise; accordingly, fees for these services are higher than for more common commercial or corporate investigation services.

Employees as Intermediaries and Main Perpetrators

Perpetrators do not only act from the outside; in many cases, they are internal employees who harm their employer or seek personal enrichment (e.g. by accepting bribes, using stolen data for their own business venture or by extorting their employer). For internal staff, it is easy to install audio or even video recording devices in a meeting room or possibly even in the managing director’s office. Behind such activities, a competitor is responsible in most cases. They pay your regular employees for spying, or may even have placed them deliberately in your company to harm you and gain access to your confidential information. Often perpetrators pursue a dual strategy, combining the eavesdropping attack with data exfiltration via malicious software within your IT. Through investigations into the origin of the data leak, the perpetrator(s) can be identified in most cases in a legally admissible manner.

Our academically trained IT specialists and experienced counter-surveillance experts in Zurich detect the corresponding devices and software, thereby preventing further leakage of your trade secrets. The anti-espionage experts of Kurtz Detective Agency Switzerland are also happy to support you preventively, identifying internal security gaps or conducting closer background checks on your employees.
