  • Surveillance Services (Singapore Only)
  • We assist businesses and employers through the use of sophisticated psychological interviewing and polygraph testing, to screen and assess the truthfulness of their employees in cases of alleged / suspected / confirmed fraud, corruption, theft, insider collusion with syndicates, insider sabotage, leakage of business secrets, misconduct etc. The process helps exonerate the innocent in as much it identifies the guilty. This type of cases usually require more than one person to be tested. Ask for bulk discounts. Typical case scenarios include:

    • Corporate and Business surveillance
    • Insurance claims investigations
    • Matrimonial & Relationship Investigations
    • Adolescent Activity & Youth Problems
    • Investigating a person's lifestyle

    Using the most advanced technology, and some of the best surveillance equipment available, our surveillance operatives are able to carry out effective surveillance from either moving vehicles, on foot surveillance, and covert close proximity surveillance in buildings or bars / clubs etc (using hidden cameras). We have at our disposal cars, specially equipped static vans, motorbikes and even specialist camouflage clothing and equipment. We are able to initiate and complete the surveillance, gain the necessary information and photography and disappear without the subject ever being aware of our existence.

  • Discrete Executive Background Checks
  • When you need a discrete background check to learn the truth about someone, Polygraph Investigative has a background check designed to meet your needs. Each background check is unique and what may be relevant in one case is not in another. As licensed private investigators we know what information is possible to develop and how to provide an accurate, detailed background check no matter where your subject resides. We also know that it is very important to consider who we are investigating when determining what type of background check you need and what records you expect us to find.

  • Computer Forensic Investigation
  • Over 90% of the world’s business and personal documents are drafted on computers. With the widespread use of e-mail, instant messaging and internet business by nearly everyone, much of today’s case evidence can be derived from computers. Polygraph Investigative Services has a computer forensic investigation team with the ability to locate and recover any and all relevant information that may exist on a computer or storage device. This includes recovering items such as e-mails viewed but not “saved”, websites visited, deleted documents, uninstalled software, etc. Unlike a piece of paper which only shows us what we can see, electronic data can have information about its creation, multiple versions of that information, who it was transmitted to, history of its use, etc. If a piece of information exists on a computer or storage device, we will be able to locate it and produce it for inclusion in evidence.
