Unlawful eavesdropping is a real threat to businesses, organisations and individuals. We identify and eliminate technical threats – from hidden microphones to compromised digital devices.
Eavesdropping is no longer a threat reserved for intelligence agencies and large corporations. With today's technology, advanced surveillance equipment can be purchased for a few hundred kronor and installed in minutes. Trade secrets, negotiation strategies and personal communications can be compromised without you noticing.
Our counter-surveillance service – also known as TSCM (Technical Surveillance Countermeasures) – involves a systematic search for technical threats in your premises, vehicles or digital devices. We identify any devices and provide concrete recommendations for protecting yourself going forward.
Hidden microphones or transmitters in offices and meeting rooms
GPS trackers on vehicles
Compromised mobile phones or computers
Eavesdropping via Wi-Fi networks or Bluetooth
Optical eavesdropping through windows (laser-based)
The threat profile varies depending on your business and position. We tailor the inspection to your risk profile.
A counter-surveillance sweep requires both technical equipment and experience. We conduct a systematic search covering the most common threat vectors.
We scan radio frequencies to identify active transmitters – hidden microphones, wireless cameras and GPS trackers communicating via radio.
We conduct a thorough physical examination of premises, furniture, outlets, ventilation and other places where technical equipment can be concealed.
We examine your Wi-Fi network and local network infrastructure for unauthorised devices, anomalous traffic or security vulnerabilities.
We check mobile phones, computers and tablets for spyware, unauthorised applications or configuration changes.
When needed, we check vehicles for GPS trackers, hidden microphones or other devices.
The result is compiled in a report with any findings and concrete recommendations for strengthening your protection going forward.
We discuss your situation and risk profile. What needs to be protected? Which threats do you consider most relevant?
We plan the inspection based on your premises, devices and specific requirements. The inspection can be conducted during or outside working hours.
The inspection is performed discreetly and systematically. Depending on scope, it takes a few hours to a full working day.
You receive a report with findings (or absence of findings), risk assessment and recommendations for future protection.
Counter-surveillance inspection of your own premises, vehicles and devices is fully legal. It is the person eavesdropping who is breaking the law – not the person protecting themselves. Unlawful eavesdropping is a criminal offence under the Swedish Penal Code.
Technical sweeps and searches in your own premises, RF scanning, physical inspection, network analysis, device screening with your consent.
Installation of surveillance equipment without consent from all parties, eavesdropping on third parties, actions requiring police authority.
The report can be used as evidence when filing a police report if unlawful eavesdropping is detected, and as documentation of security measures taken.
The short answer: you probably don't. Modern surveillance equipment is extremely difficult to detect without professional equipment. That is precisely why a technical inspection is important if you have reason to suspect it.
It depends on the area and scope. A single office room typically takes 1–2 hours. A full inspection of an office suite with multiple rooms takes half a day to a full day. Vehicle inspections normally take 30–60 minutes.
If your business handles sensitive information, we recommend regular inspections – for example quarterly or before important meetings and negotiations.
The price depends on the size of the premises and the scope of the inspection. Contact us for a quote based on your specific needs.
