Technical Surveillance Counter Measures: bug sweeps, electronic counter surveillance, and secure environment certification for executives, attorneys, and high value targets.
TSCM. Technical Surveillance Counter Measures. Is the discipline of finding and neutralizing covert electronic surveillance: hidden cameras, audio bugs, GPS trackers, compromised phones, and the network level attacks that increasingly accompany physical surveillance. We give TSCM services for Manhattan executives, matrimonial clients during divorce proceedings, attorneys before sensitive depositions, and corporate clients securing boardrooms, conference rooms, and executive residences.
Most TSCM clients fall into one of four categories: executives who suspect a hostile takeover or corporate espionage situation, attorneys before sensitive depositions or settlements, high net worth people in contested divorces, and victims of stalking who suspect electronic monitoring. The signals are usually subtle. Conversations that 'leak,' a phone behaving oddly, the sense that a competitor knows things they shouldn't.
A professional TSCM sweep uses spectrum analyzers, non linear junction detectors, thermal imaging, and physical inspection. Not consumer 'bug detector' apps from the iPhone store, which find essentially nothing real. We sweep RF spectrum across the frequencies modern bugs use, identify any unauthorized electronic device, locate it physically, document it, and either remove it or preserve it in place if law enforcement is going to be involved. A real sweep of a typical office takes hours. We don't do drive by inspections.
Modern surveillance is rarely just hardware. We coordinate physical TSCM sweeps with digital forensic work. Examining devices for spyware, reviewing network traffic, checking cloud accounts for unauthorized access, and securing communications going forward. For high value targets we'll set up an ongoing monitoring relationship rather than a one time sweep.
TSCM is unusual because the discovery process is itself something a complex adversary may be watching for. We arrange sweeps in ways that don't tip off whoever planted the surveillance. Including not driving marked vehicles to your office, scheduling sweeps during cover stories like cleaning crews or IT visits, and coordinating with you directly rather than through any intermediary.
A technical surveillance counter measures (TSCM) sweep is priced by the size and complexity of the space being swept. A single office or vehicle versus a full residence, office suite, or boardroom. Rather than by the hour.
The main things that move the fee:
A focused single room or vehicle sweep typically starts in the low four figures; a full residence, office suite, or boardroom scales up with the area and depth of the inspection. Every case is quoted individually. The initial consultation with David is free and confidential, and you’ll get a written estimate before any work begins, with no obligation.

TSCM stands for Technical Surveillance Countermeasures. A professional sweep that detects hidden cameras, audio bugs, GPS trackers, and unauthorized listening or transmitting devices in a home, office, vehicle, or boardroom. It is the work of physically finding and neutralizing eavesdropping equipment.
Common signs include private remarks that get back to others, a partner or competitor who seems to know things they should not, unfamiliar objects or wiring, devices that behave oddly, or a vehicle that is always one step ahead of you. If something feels off, a sweep settles the question.
Our technicians use spectrum analyzers, non linear junction detectors, thermal and physical inspection to examine the space methodically. Walls, fixtures, electronics, furniture, and vehicles. We identify any device found, document it, and advise you on whether to remove it or preserve it as evidence.
Yes. You have every right to inspect property you own or control for surveillance devices. Finding and documenting an illegal listening or recording device can itself be important evidence in a divorce, corporate dispute, or criminal complaint.
High sensitivity environments. Executive suites, boardrooms, legal and financial offices. Benefit from periodic scheduled sweeps and a sweep before any major negotiation, board meeting, or deal. We can advise on a sensible cadence for your risk level.
A TSCM sweep is priced by the size and depth of the inspection, not by the hour. A focused single room or vehicle sweep typically starts in the low four figures, and a full residence, office, or boardroom scales up from there. We give a fixed quote for the scope after a brief confidential call.
