TSCM · Technical surveillance countermeasures
Periodic TSCM contract
A sweep is a photograph of that day. If the risk is continuous, assurance should be too.
Why periodic?
A device can be placed after a sweep. A periodic programme takes the "clean" state of the first sweep as a baseline and tracks change in later ones: newly added objects, a changed RF environment and new devices become easier to see.
How is the frequency set?
Frequency is set by risk level, the sensitivity of meetings and the number of people who access the rooms. More frequent sweeps are planned for high-risk boardrooms and less frequent ones for general office areas. We give our recommendation in writing after discovery.

How we work
Confidential initial call
We talk on a secure channel away from the space and devices you suspect. We listen to what, where and why you suspect, and define the scope.
Appointment and security
The sweep date is discussed only with the people who need to know and away from the space to be swept. No sensitive talk takes place in the space beforehand.
Physical inspection
The space and its items are inspected visually: sockets, ceiling, lighting, electronics, furniture and newly added objects.
Technical sweep
Devices are searched for with RF spectrum analysis, NLJD, thermal imaging, optical lens detection and line/network analysis.
Findings and evidence preservation
If a suspect device is found it is not moved; it is photographed and its position and technical measurements recorded. The next step is decided with you and your lawyer.
Report and recommendations
Method, equipment, findings, risks and corrective recommendations are delivered as a written report.
