A Polygraph Test concerning allegations of Theft is one of the most effective tools that can be utilised when attempting to identify the perpetrator of a theft, to recover stolen items and to confirm a person’s innocence. Testing can be conducted privately if there are allegations of theft within the family, or within a business setting for multiple persons if there is a larger pool of suspects.

A Polygraph Test concerning allegations of Theft is one of the most  effective tools that can be utilized when attempting to identify the suspects of that theft and to not only recover the stolen items but also to confirm a person’s innocence if they have been falsely mistaken as the suspect of the alleged crime. At Polygraph Serivces, testing can be conducted privately and for a single person if there are allegations of theft within the family, or within a business setting and for multiple persons if there is a larger pool of suspects.

Your business may have experienced financial loss due to stolen merchandise or stock. Or perhaps there is potential for greater financial loss, due to a security breach or failing in cyber security which has led to personal data or company software being stolen. Cyber security companies may be able to whittle down the suspect pool but, in circumstances where the suspect has gone unidentified a polygraph test is an effective means in identifying the culprit.

To establish you are hiring the right applicant for your business, tests can be conducted for prospective employees to ensure truthful and honest disclosures have been made throughout the application process. Testing of existing employees is an effective method of investigation when issues arise within the workplace, from substance abuse, allegations of sexual harassment to theft. Periodic screening of existing employees can also be carried out to confirm your employees continue to remain clear of any wrongdoings.
