Defend Against Electronic Espionage

NSI Global provides specialist Technical Surveillance Counter Measures, also known as TSCM, electronic bug sweeping, surveillance detection and listening device detection, for government agencies, law enforcement bodies, law firms, corporate organisations, executives, and authorised case-managed matters across Australia.

Our TSCM services assist with the detection, assessment and mitigation of covert surveillance threats, including hidden cameras, listening devices, unauthorised transmitters, GPS trackers, wiretap devices, phone interception risks, network-based surveillance concerns and other technical security vulnerabilities.

NSI Global does not provide direct private residential TSCM services to members of the public. Residential, domestic violence, family law, child safety, criminal, civil or case-managed surveillance matters must be referred or instructed through a law firm, law enforcement agency, government department, recognised support organisation, authorised investigator or case officer.

What Is TSCM?

Technical Surveillance Counter Measures (TSCM) is the specialist process of detecting, identifying and mitigating covert surveillance threats within physical, electronic and communications environments.

A TSCM sweep may involve the inspection of offices, boardrooms, secure rooms, residences, vehicles, vessels, aircraft, telephones, network infrastructure, radio frequency environments and other sensitive areas where confidential conversations or information may be targeted.

TSCM is commonly used to help identify:

  • Hidden cameras
  • Listening devices
  • Covert microphones
  • GPS trackers
  • Wiretap devices
  • Unauthorised transmitters
  • Radio frequency surveillance threats
  • Phone and network interception risks
  • Technical vulnerabilities in sensitive meeting areas
  • Indicators of covert or unauthorised surveillance activity

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.

Decades At The Forefront Of Counterintelligence
