Technical Sweeping Services (TSCM)

Professional detection, identification, and neutralisation of covert surveillance devices and electronic eavesdropping in sensitive facilities.

What Is TSCM?

Technical Surveillance Counter-Measures (TSCM) — commonly known as "sweeping" — is the systematic process of detecting, locating, and neutralising covert surveillance devices planted within a facility. These devices may include hidden microphones, cameras, GPS trackers, telephone line intercepts, and wireless transmitters designed to capture confidential conversations, data, and activities.

TSCM is a critical security discipline for any organisation that handles sensitive information — government ministries, diplomatic missions, corporate boardrooms, legal firms, financial institutions, and defence facilities. The presence of even a single covert device can compromise negotiations, expose proprietary information, and undermine strategic advantage.

Why Organisations Need TSCM

Corporate espionage, state-sponsored surveillance, and competitive intelligence gathering represent growing threats to organisations of all sizes. A single covert device can compromise negotiations, expose proprietary information, and undermine strategic advantage that has taken years to build.

Regular TSCM inspections are an essential component of information security hygiene — as fundamental as cybersecurity audits or physical penetration testing. Organisations that handle classified, commercially sensitive, or legally privileged information should conduct sweeps on a scheduled basis and following any event that may have provided access to adversaries, such as maintenance visits, contractor access, or suspicious behavioural indicators.
