TSCM · Technical surveillance countermeasures
Office and meeting room bug sweep
Secure the room where your trade secrets are discussed, by measurement, before an important meeting.
What is searched for in offices?
Meeting tables, ceiling panels, light fittings, sockets and power strips, projectors and phone sets, air-conditioning vents, wall clocks or pictures, and recently left gifts or objects are examined. The conference system, IP phones and network devices in use are also checked.
An acoustic leakage test is also suggested to measure whether speech passes to the next room or corridor.
When should you sweep?
Before a commercial negotiation, merger or acquisition talks, a board meeting, after staff changes, building works or an office move, and whenever there is a sign that secrets are leaking. For institutions under constant risk, a periodic sweep is suitable.

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.

FAQ
Frequently asked questions
Can staff be in the room during the sweep?
No. For confidentiality the room should be empty during the sweep. Besides the sweep team only an authorised person is present.
Can it be done during working hours?
Preferably outside working hours or when the room is unused; we plan it together.
