Who needs a polygraph test in private investigations, and why?

Critical Aspects of Private Investigations

First and foremost, there are key factors that are most frequently examined during independent investigations to identify hidden risks, instances of fraud, or data breaches.

Corporate embezzlement

Have you misappropriated company funds or property for personal gain?

Have you been involved in creating fictitious shortages or falsifying financial statements?

Have you received illegal kickbacks from contractors or clients?

Data breach

Have you disclosed the company’s confidential information to third parties or direct competitors?

Have you used company information for personal gain or to start a side business?

Have you concealed instances of unauthorized copying of databases or intellectual property?

Professional loyalty

Are you involved in a secret collusion with competitors aimed at undermining the company's operations?

Have you planned any deliberate actions to discredit the organization's leadership or image?

Are you concealing a second job that conflicts with the company's interests?

Verification of alibis and evidence

Did you lie about your exact whereabouts at the time of the incident or crime?

Are you concealing the fact that you destroyed evidence, documents, or digital traces that are important to the investigation?

Did you frame innocent people to divert suspicion away from yourself or your accomplices?

The accuracy of the biography

Did you conceal any criminal convictions, deportations, or legal proceedings when applying for a job?

Did you provide knowingly false information on your educational records, diplomas, or certificates?

Did you conceal the true reasons for your dismissal from previous jobs related to disciplinary violations?

Hidden risk factors

Do you hide the fact that you have a gambling addiction (ludomania) or other harmful habits?

Have you used company funds to pay off gambling-related debts?

Do you associate with individuals involved in the illegal trafficking of controlled substances?

Financial Risks

Do you have any hidden debts, loans, or obligations that might push you to commit a crime?

Have you made any unjustified large expenditures for which you cannot officially verify the source of the funds?

Have you concealed the fact that you managed company assets for your own personal gain?

Hidden Connections and Influences

Are you under the influence of individuals associated with criminal organizations or representatives of competitors?

Do you conceal meetings with individuals included on the company’s or law enforcement agencies’ “blacklists”?

Have you received instructions from third parties to take actions that would harm the investigation?

What can be determined after a polygraph test during an investigation?

In addition, polygraph testing as part of private investigations helps elicit honest answers to critical questions that cannot be clarified by other means. You will be able to find out:

Analysis of Involvement in the Incident

It allows for the reliable confirmation or refutation of the respondent’s involvement in embezzlement, fraudulent schemes, or the disclosure of confidential information to third parties.

Investigation of financial fraud

Indicates whether there were any hidden financial transactions, kickbacks, secret debts, or other obligations that harm the interests of the business.

Identifying Hidden Risks

Identifies the presence of harmful habits, addictions, or ties to competitors and criminal organizations that may be the cause of the offense.

Evidence-based decision-making

It provides objective facts that enable you to make an informed decision regarding continued employment, termination, or reporting the matter to law enforcement.
