Technical Surveillance Counter Measures

Adopt a multi-layered approach of security to counter technical surveillance

The threat posed by illicit intelligence never goes away, ranging from criminals attempting to profit financially to sophisticated state-sponsored enemies seeking political and military advantages. A strong security policy covering physical security, cyber security, and protection from electronic surveillance is required to ensure that secrets stay secret, even when we are unable to predict all potential risks.

Technical Surveillance Counter Measures(TSCM)

The quest for illicit intelligence is an ever-increasing threat in the modern data-driven world, from criminals trying to obtain information for financial gains to sophisticated state-sponsored adversaries looking for political and military gains. While it is not always possible to know every threat present around us, a robust security policy encompassing physical security, cybersecurity, and protection from electronic surveillance is necessary to ensure that your secrets remain secret. Small, inexpensive surveillance devices can compromise all the security of your building, your Sensitive Compartmented Information Facility (SCIF), your private conversations, and your plans and secrets.

Netrika’s Technical Surveillance Countermeasures approach is unique and can greatly improve the security of your organisation as a whole. We conduct a full on-site risk assessment before each survey.


The TSCM services provided by Netrika cover the following aspects:

Technical surveillance countermeasures include electronic eavesdropping detection, anti-surveillance devices, wiretap and covert camera detection, technical security, and communications security.

The threats posed by electronic surveillance make technical surveillance countermeasures crucial. The concept of a tiny microphone or other bugs being concealed in a conference room is surprisingly common.

Technical Surveillance Countermeasures (TSCM) - Techniques and measures to detect and nullify a wide variety of technologies that are used to obtain unauthorized access to classified national security information, restricted data, and/or sensitive but unclassified information.
