Our Position

Truth verification done right

Our mission is to make truth verification accessible, reliable, and ethical. We carefully vet every examiner before adding them to our network, ensuring they possess the skills, experience, and training to deliver accurate and trustworthy results. Whether you’re seeking the truth in a legal matter, investigating workplace theft, or resolving a personal dispute — our professional examiners are here to provide the answers you need.

We are committed to promoting the polygraph as the only scientifically validated technology for truth verification. Unlike unproven alternatives — such as voice stress analysers, mobile applications, and eye-tracking tools — polygraph testing is supported by decades of peer-reviewed research and real-world application across law enforcement, government, and the private sector.

Principles Register

Six principles behind every examination

Each entry in this register is a commitment we hold ourselves to on every case, without exception.

People

Professional examiners only

Every examiner graduated from an APA-, BPS-, or EPA-approved polygraph school and conducts tests to APA standards and protocols. No trainees, no unqualified operators — guaranteed. Many are former law enforcement with forensic psychophysiology expertise.

Vetting

Rigorous admission process

We screen every examiner for credentials, field experience, ethics, and professional reputation before they join our network, and continuously monitor performance to maintain the highest standards.

Privacy

Total confidentiality

Client privacy is non-negotiable. Results are shared only with you. Examinations take place in private, discreet & climate-controlled venues, by appointment only. No branded vehicles, no visible advertising, no disclosure to third parties.

Equipment

Advanced instruments

We use state-of-the-art digital polygraph instruments with the latest validated methodologies. Our examiners are also trained in detecting and countering deceptive tactics and countermeasures.

Pricing

All-inclusive pricing

Every price covers the booking fee, examination, pre-test assessment, and fully detailed report. No hidden costs, no surprises. Only a $100 deposit required upfront.

Reporting

Detailed reporting

Every client receives a comprehensive, written polygraph report detailing findings and conclusions. Our examiners can also provide expert testimony and documentation suitable for legal proceedings, where permitted.

The Vetting Ledger

How an examiner earns a place in our network

Admission is deliberately demanding. Every examiner passes each stage below before taking a single case — and after booking, one is individually assigned to you and your case details.

Credentials

Credential verification

We verify all certifications, licences, and training records. Every examiner graduated from a polygraph school approved by the APA, BPS, or EPA — institutions recognised worldwide as the gold standard in polygraph education.

Experience

Experience assessment

We require significant field experience across a range of case types — including infidelity, theft, legal defence, and corporate investigations. Many of our examiners are former law enforcement professionals.

Integrity

Ethics & background review

Every examiner undergoes a thorough background check and ethics review. We assess professional conduct history, adherence to industry codes, and personal integrity.

Method

Equipment & methodology

Examiners must use approved digital polygraph instruments and follow validated, evidence-based testing protocols. No outdated equipment or unscientific techniques.

Review

Ongoing monitoring

Acceptance into our network is not permanent. We continuously monitor examiner performance, client feedback, and adherence to standards, with ongoing professional development.

Beware of unqualified examiners

The accuracy of a lie detector test depends on the skill of the examiner, not the machine. Unfortunately, unqualified individuals operating without proper training continue to damage the industry’s reputation and deliver unreliable results. Always verify your examiner graduated from an APA-approved school and uses validated testing protocols.
