Government TSCM Sweeps and Espionage Consulting

Canberra, Sydney, Melbourne and Australia Wide

Government Level Technical Surveillance Counter Measures (TSCM)

Uniquely positioned in the Nation’s Capital, Canberra, our team of highly specialised operatives are available to provide Government Level Technical Surveillance Counter Measures sweeps and  Espionage Risk Auditing of all types of premises, including offices, boardrooms, vehicles, to whole buildings. Government departments nowadays need to safeguard against economic and state sponsored espionage. Industries and companies around the world utilise espionage and intelligence gathering techniques to further their interests and gain the upper hand when negotiating contracts and so on.

NSI specialises in conducting Government TSCM Sweeps and Espionage Consulting which includes technical surveillance countermeasures sweeps, counter espionage and counter surveillance consulting for all types of government departments including parliamentary offices, members of parliament and local councils.


All NSI Bug Sweep Teams use equipment that is utilised by Intelligence agencies, Defence departments and governments worldwide.
The highly specialised equipment we use is also utilised by the Department of Defence (DOD), the Department of Foreign Affairs and Trade (DFAT), and the Australian Signals Directorate (ASD), among others.

NSI has committed over seven figures to constantly equip its teams with the highest spec equipment. With this equipment, we are able to detect the presence of active and passive bugging devices, digital burst/packet bugs, hidden camera setups, keystroke logging devices, telephone interception and wiretaps, laser microphones, infrared beams, and more.

All of our TSCM teams can currently scan up to 90 GHz in real time, more than any other TSCM provider in the country.

As a comparison, devices used by other companies in Australia will generally scan up to 12 GHz and only some companies will have a 24 GHz capability.

Beware anyone who tells you this is not necessary. They may be making excuses for not having the clearance, training, or budget necessary to purchase this highly specialised equipment. Worse yet they may be unaware or inexperienced with detecting the latest crop of 5G capable devices and threats in unlicensed bands up to 90 GHz.

The Australian Communications Media Authority (ACMA) are fast-tracking super high to extremely high frequencies. These frequencies, far exceeding 24 GHz, are a regular occurrence in the Asia Pacific Region. NSI has detected burst transmitters operating at these frequencies both in Australia and Internationally since 2008.

What is the Unique NSI Methodology?

What is unique to NSI is that we assess your ENTIRE working environment including the premises, the staff, your practices, your technology, and external threats. We have Security Cleared inspectors that conduct all Government Level TSCM sweeps.

After completing a full technical threat assessment, a bespoke security package is designed for your specific environment and circumstances. We uncover every vulnerability that rogue elements would exploit in order to steal from or damage you.

Part of this is your TSCM Bug Sweep which comprises of:
  • Physical search for hidden transmitters, microphones, and cameras.
  • Radio frequency spectrum analysis;
  • Non-Linear Junction Evaluation;
  • Thermal Emissions Analysis;
  • Telephone and network analysis;
  • VoIP system analysis;
  • Electronic inspection for covert video setups;
  • Carrier current analysis of AC outlets and cabling throughout the premises.
