A TSCM survey, also known as Electronic Bug Sweep, is a service provided to detect the presence of and report on, hidden technical surveillance devices and hazards. It also identifies technical security weaknesses that could aid in the conduct of a technical penetration of the surveyed premises.
The practice of illegal electronic surveillance for intelligence gathering is a significant threat experienced by all industries as well as the private sector. This can vary from illegal surveillance and stalking of at-risk individuals, criminals trying to obtain information for financial gain, competitors attempting to gain strategic insight, to experienced state-sponsored actors seeking political and/or military advantages.
Many organisations may not always be certain who is targeting them, and which of their vulnerabilities are being exploited. In these circumstances, it is imperative that a Technical Surveillance Counter Measures (TSCM) sweep is conducted.
