SPECIALIZED POLYGRAPH TESTS

Complete resolution of any given polygraph requirement will always be our priority and remains our primary focus.

The mere issuing of a passed or failed polygraph examination result will often do little to achieve this goal. Our resolution rate, as tracked on a monthly basis since 2009, fluctuates around an 89% average.

True Lies Polygraph Examiners are all professionally trained, internationally accredited and conduct all examinations to the international standards set by the American Polygraph Association (APA). The Senior team members are also accredited Criminal Investigators with extensive investigative background both within and outside of the South African Police Service (SAPS).

Continued education is a prerequisite of all those attached to the True Lies office and advanced polygraph courses are undertaken on a regular basis. Our Cape Town operating region and contact base is extensive, covering a vast number of fields.

Our Investigators have the ability and expertise to conduct forensic assessments on all subjects who are engaged, including those who refuse polygraph testing. Using various conventional interrogative techniques, as well as multiple forms of criminal and background screening, a comprehensive evaluation of such subjects can be achieved. In this way, inconsistencies in evidence, elevated risk and/or serious breaches of trust can be highlighted without any negative precedents being set, or unnecessary cancellation costs being incurred. This capability is not the norm within the industry.

The polygraph is an exceptional investigative tool when utilised ethically and as prescribed by the American Polygraph Association, to international standards. Administered correctly by a properly skilled professional, the polygraph can be applied within a multitude of scenarios and environments where any one of the following outcomes is critical:

1. Proactive risk management within any field.

2. The on-going monitoring and/or management of internal risk within a given environment.

3. Reactive risk management in so far as the investigation of any internal risk and/or crime-specific event.

The following list some instances where we have used polygraph testing effectively to identify and resolve various concerns relevant to the management of crime and/or risk within a given environment:

Pro-active applications:


  • Recruitment of staff: Very specific processes have been formulated to prevent the injection of unnecessary risk to the working environment by the introduction of high-risk individuals. These include comprehensive screening and verification processes, using polygraph.
  • Security related issues, prior to placement of staff in sensitive positions.
  • Routine testing to establish criminal activity and maintain sound work ethics within any given environment.

On-going risk management:


  • Safeguarding of intellectual property: Polygraph testing can be used to regularly vet staff who have access to critical information in order not only to protect but also to deter any level of corruption within such high-risk environments.
  • Monitoring of high-risk environments: By engaging staff on a random, on-going basis, a platform is created whereby the early detection of risk within any given working environment is effectively created, which otherwise would not be the case, leading to a vast reduction in illicit activity within the given setting.

Reactive applications:


  • Screening of potential suspects: When used correctly by a well-trained and properly skilled investigator, the use of the polygraph test can not only assist in identifying viable persons of interest but also greatly reduce the focus of any given investigative process, greatly reducing the time and resources needed to successfully address such matters.
  • Evaluation of evidence: Polygraph testing has the added ability to assist investigators in correctly quantifying various forms of evidence and in so doing, expedite such processes by avoiding unnecessary investigative avenues from being pursued.
  • Internal disciplinary investigations: The use of this tool can quite easily resolve and/or clarify any given aspect of evidence offered by those engaged in such processes and/or bring clarity in so far as disputed aspects of any such undertaking.
  • Official SAP investigations: Where required, our investigators have the ability to shadow any official police investigation and assist with such processes in any of the ways mentioned above, using both conventional investigative techniques, as well as polygraph testing.
  • The investigation and resolution of any criminal event and/or action.
  • Exploration and exposure of syndicated criminal activity within any given scenario.
  • Resolution of any disciplinary matter – where facts are contested or where single witness evidence complicates such a process.
  • Sexual harassment and/or related offences.
  • Drug or substance abuse issues including drug testing.
  • Specific issue polygraph testing of any nature.
  • Exploration of conflicting evidence including alibi verification.
  • Insurance claim verification.

Of extreme importance to note is that the value of the aforementioned processes rests on three critical facets:


1. The legality of the administration of all testing done and the means by which relevant evidence is obtained.

2. The skill set of the examiner/investigator engaged to undertake such processes with specific reference to appropriate investigative experience and understanding of the laws of criminal procedure and evidence.

3. The ability of the examiner to resolve failed polygraph outcomes, without which the use and scope thereof becomes disproportionately limited.
