A Complete Truth Verification Solution
From investigating workplace misconduct to screening new hires before they walk through the door – we offer a full range of polygraph and vetting services, tailored to your specific situation.
Investigative Examination
When theft, misconduct, or dishonesty has occurred in the workplace, we help identify those responsible, exonerate the innocent, and recover stolen assets.
Pre-Employment Screening
Avoid costly hiring mistakes. Our pre-employment polygraph screens candidates for criminal history, dishonest behaviour, and substance abuse before you make a commitment.
Periodic Testing
Regular polygraph testing is a proven deterrent. Annual, quarterly, or ad-hoc scheduling helps maintain a culture of honesty and integrity across your organisation.
Pre-Employment Vetting
Criminal record checks, qualification verification, and credit checks - a complete background screening package recommended for any position of trust or financial responsibility.
CCMA & Legal Support
Our examination results are CCMA-accepted and properly documented. Maryna is available to provide expert witness testimony in disciplinary hearings and legal proceedings.
