Defend Against Electronic Espionage

Covert surveillance technology is smaller, cheaper, and easier to deploy than ever before. Radio frequency devices remain the most common method used to gather intelligence on Australian government departments, law firms, corporations, and high-profile individuals — often without the target ever knowing a breach occurred.

NSI Global’s TSCM Unit conducts thorough visual, electronic, and physical examinations to detect covert surveillance devices, domestically and internationally. Every sweep concludes with a comprehensive written report and clear recommendations to close identified vulnerabilities.

What Is TSCM?

Technical Surveillance Counter Measures (TSCM) is the specialist process of detecting, identifying and mitigating covert surveillance devices — hidden microphones, cameras, GPS trackers, burst transmitters, 5G bugs, and signal interception equipment — within physical, electronic and communications environments through a systematic inspection of a premises, vehicle or communications infrastructure.

When Should You Consider a TSCM Sweep?

A TSCM bug sweep should be considered when an organisation, government agency, law firm, executive team, or authorised case officer has concerns that confidential information, sensitive conversations, or secure environments may have been compromised. Common reasons to request a TSCM inspection include:

Unexplained Information Leaks

Sensitive commercial, legal, government, operational or privileged information appears to have been disclosed without authorisation.

Boardroom, Executive or Legal Meeting Protection

Confidential discussions are being held in boardrooms, executive offices, legal conference rooms, secure facilities or temporary meeting locations.

Security-Cleared Protection Needed

You handle highly classified or sensitive information (e.g. government or defence projects) and require a security-cleared TSCM provider to sweep for state-sponsored espionage devices. NSI’s team is vetted by the Department of Defence and adheres to the elevated standards required by government clients.

Government, Defence or Law Enforcement Security

A government agency, law enforcement body, defence-adjacent organisation or security-cleared environment requires technical surveillance detection support.

Corporate Espionage or Insider Threat Concerns

An organisation suspects competitive intelligence gathering, unauthorised surveillance, insider-enabled compromise, contractor-related risk or repeated information leakage.

Legal or Case-Managed Surveillance Concerns

A law firm, case officer, recognised support organisation, investigator, law enforcement body or government agency requires residential or personal-safety-related TSCM support in a sensitive legal, domestic violence, family law, child safety, criminal, civil or protective matter.

Vehicle, Residence or Mobile Environment Risk

Sensitive conversations, movement patterns or operational details may be exposed through surveillance devices placed in vehicles, residences, aircraft, vessels or mobile working environments.

Who Can Engage NSI Global for TSCM?

NSI Global’s TSCM services are available to government departments, law enforcement agencies, law firms, corporate organisations, and case-managed legal matters. NSI Global does not provide direct private residential TSCM services to members of the public — residential and domestic matters must be engaged through a legal representative or case officer.

This approach ensures every engagement meets the standard of discretion, evidentiary rigour, and legal defensibility our government, legal, and corporate clients require.

Frequently Asked Questions

Who can request a TSCM sweep from NSI Global?

NSI Global works with government departments, law enforcement, law firms, and corporate organisations. Private individuals seeking residential TSCM must be referred through a legal representative or case officer.

Does NSI Global provide TSCM sweeps for private residences?

Not directly to members of the public. Residential and domestic TSCM matters are engaged through a legal representative or case-managed referral, ensuring the engagement meets the same evidentiary standard as our corporate and government work.

What's the difference between TSCM and cyber security?

TSCM addresses physical and radio-frequency surveillance threats — hidden microphones, cameras, and transmission devices. Cyber security addresses digital network and systems threats. Many sensitive matters require both, and NSI Global's broader digital forensics capability covers the cyber side.

Can NSI Global conduct TSCM sweeps internationally?

Yes. NSI Global has conducted TSCM sweeps domestically and internationally for government, corporate, and high-net-worth clients.
