Bug Sweep & Surveillance Detection (TSCM)
For law firms, private clients, and high-risk environments
Most clients contact us because they are concerned that a private space, vehicle, or meeting environment may be subject to covert monitoring. This may follow a dispute, litigation, sensitive negotiation, unexplained information leaks, or a general suspicion that confidentiality has been compromised.
Cyber Defence, Evaluation & Consultancy Ltd (CDEC) provides professional bug sweep and Technical Surveillance Countermeasures (TSCM) services for law firms, private clients, executives, and organisations operating in high-risk or high-value environments where privacy and discretion are critical.
Our bug sweep services are designed to identify covert listening devices, hidden cameras, GPS trackers, and illicit wireless transmissions that may be used for surveillance or intelligence gathering. Sweeps are conducted in offices, boardrooms, private residences, vehicles, and temporary locations such as hotels or short-term accommodation.
We are typically instructed by:
Law firms handling sensitive litigation, disputes, or confidential negotiations
Private clients concerned about targeted surveillance or information leakage
Organisations dealing with insider threats, corporate espionage, or hostile interest
All inspections are carried out discreetly using specialist technical equipment and proven investigative methodologies, with minimal disruption to the environment. Our work focuses on identifying real surveillance risk, not simply cataloguing electronic devices.
Unlike basic “bug detector” scans or checklist-based inspections, our approach is analyst-led and risk-driven. We assess how surveillance would realistically be deployed, what indicators matter, and whether findings represent benign activity or genuine compromise.
Bug sweep engagements often take place alongside, or are informed by, OSINT and digital exposure investigations, recognising that physical surveillance is frequently preceded by online research, profiling, or targeting.
Findings are reported clearly and confidentially, explaining what was found, what it means, and what action, if any, is required to restore privacy and reduce future risk.
