Counter Espionage


One of Group One Investigation’s areas of expertise is counter espionage (or counterintelligence, to use another term). In a nutshell, spying on anyone who is spying on you. In counter espionage investigations, we work to identify and counteract activities which cause a threat to personal, professional and corporate security. These threats can come from hostile intelligence organisations or from individuals engaged in espionage or sabotage, subversion or even terrorism. Private investigative counter espionage investigations can protect you and your company from theft, fraud, untrustworthy employees, and dishonest competitor practices and ensure your corporate security is tight, protecting you from corporate espionage both at your physical premises and online.

Group One Investigations has decades of experience in counter espionage.


Our highly skilled team uses state of the art equipment and innovative techniques to facilitate effective investigations which bring our clients peace of mind. Some common investigative techniques used in counter espionage are:

  • Collective Counterintelligence - gaining information about an opponent’s intelligence collection capabilities
  • Defensive Counterintelligence - thwarting efforts by hostile intelligence services to penetrate the service
  • Offensive Counterintelligence - having identified an opponent’s efforts against the system, we can manipulate these attacks by “turning” the opponent’s agents into double agents or feeding them false information on which to report

Hidden Asset Search / Finint


Finding hidden assets, offshore companies and bank accounts is an endeavour which requires an expert with a global reach.

Corporations, Governments and high net-worth individuals at times require our services to investigate embezzlement, corruption or to assist in locating hidden assets during high profile divorce cases. This type of case can also include locating offshore company structures, UBO’s (ultimate beneficial owners) and associated bank accounts.

Group One Investigations also works across FININT. Financial intelligence (FININT) is the gathering of information about the financial affairs of entities of interest, to understand their nature and capabilities, and predict their intentions. Analysis may consist of scrutinising a large volume of transactional data using data mining or data-matching techniques to identify persons potentially engaged in a particular activity. Alternatively, data mining or data-matching techniques may be employed to identify persons potentially engaged in a particular activity.


Examples of financial intelligence analysis include:

  • Detecting taxpayers trying to avoid their fiduciary obligations by moving wealth surreptitiously out of a tax-levying jurisdiction
  • Discovering safe havens where criminals park the proceeds of crime
  • Accounting for how a large sum of money handed to a targeted individual disappears (money laundering)
  • Checking to see if a corrupt individual has had any sudden and unexplained windfalls

High Net Worth Individuals
High Profile Divorce Support Services & Asset Search


High net-worth clients retain our investigative services for a variety of reasons. We may employ such tactics as covert implementation of undercover agents to seek out and investigate management fraud and theft. We can also uncover poor management practices of agents, or investigate whether management teams are stealing money and or misappropriating funds via invoice fraud or other methods.

V.I.P’s also enlist our services for security measures from Technical Surveillance Counter Measures (TSCM) such as Bug Sweeps, to pre-employment background checks on all individuals seeking employment from the gardener to the nanny. Click here to learn more about TSCM.


At times high-net worth individuals call on our services to investigate their partner, such as in cases of suspected adultery or a covert asset search prior to divorce proceedings taking place. It is always recommended to act on your suspicions prior to the other party becoming aware so that you maintain the upper hand - especially when millions of dollars are on the line.

We offer a wide range of investigative, asset tracing, offshore company and bank account tracing services plus an in-depth investigative service focused on the assets and behaviour of a partner, both during the relationship and once divorce proceedings take place. Our global reach allows us to take on with confidence any High Profile Divorce Matter with extreme confidence that we can deliver exceptional intelligence data to assist our clients both prior to and during a divorce proceeding.

Government Corruption and Fraud Support Services

Group One Investigations has extensive experience working with foreign Governments who are actively involved in investigating members of Parliament through to Ex-Presidents involved in corruption and political corruption allegations. With this we use our specialised asset tracing, offshore company and account tracing services. We have extensive experience in this field. A common investigation of this nature would involve surveillance on an individual when meeting suppliers abroad to discuss contracts and purchasing of goods and services. We have observed individuals whilst abroad on such business visit banking institutions either before or after official Government meetings to set up foreign bank accounts where kickbacks are deposited. We’ve also investigated high-end purchases such as Real Estate, boats, expensive jewellery, trips to the casino and so on.

We also have experience in assisting current day Governments trace assets connected to ex heads of state and exposing them for serious corruption offences. To find more information on our Government Corruption and Fraud Support Services, click here.

Group One Investigations has extensive experience in this highly specialised area. Some situations where Geopolitical Advisory services might be required include:

  • Security Environment Assessments
  • Monitoring Services
  • Current Events Analysis

Electronic Bug Sweep/ Technical Surveillance Counter Measures (TSCM)

The TSCM (Technical Service Counter Measures) inspection, commonly known as a “bug sweep” is a check to ensure that there is no possibility of conversations being overheard by others, and is usually conducted in an office or meeting place. A TSCM survey is the service provided by our qualified personnel to detect the presence of surveillance devices and hazards and to identify technical security weaknesses. It is also to ensure that there is nothing that could compromise the security and confidentiality of an area by the use of technical audio surveillance devices. Group One Investigations uses the latest, top of the range equipment for all such investigations to ensure nothing is missed and offer our clients total privacy and peace of mind.
