What is technical counter-surveillance (TSCM) or eavesdropping protection?

The terms counter-surveillance or eavesdropping protection refer to the technical inspection (known as “sweeping”) of premises and objects by a specially trained technician to prevent eavesdropping measures or the interception of digital data.

Counter-surveillance Strategies

Covert TSCM

All components and protocols we use are hidden. We can disguise the service as a LAN/Wi-Fi audit or other methods. Depending on the requirement, we also offer covert counter-surveillance during working hours, outside business hours, or on weekends.

We conduct thorough physical and electronic inspections. Our experts detect activated audio or optical eavesdropping devices, such as GSM, 3G, 4G and 5G mobile eavesdropping devices, wireless bugs, cable and microphone taps, phone taps, video surveillance equipment, mini-cameras, and laser or infrared eavesdropping devices.

The settings of the counter-surveillance devices can be very complex. With our equipment, we are also able to find eavesdropping devices that establish an internet connection or detect bugs even when they are not actively transmitting.

Open TSCM

Our equipment and active measures for counter-surveillance are visible to all those present. We answer questions on-site about the reason and purpose of our work in the manner previously agreed upon with you.

Upon request, we can carry out open counter-surveillance during working hours, outside of business hours, or on weekends.
