Visual Comparison: Polygraph vs P300 EEG

See the clear difference between traditional polygraph testing — with multiple sensors, straps, and stress — and the simplicity of modern P300 EEG lie detection , using only a lightweight brainwave headband.

Corporate Investigation Case Studies

Real outcomes from corporate clients. All details anonymised to protect confidentiality.

Retail — Internal Theft

£340,000 Stock Shrinkage Resolved

National retailer experiencing persistent shrinkage across 3 distribution centres. Traditional CCTV investigation had failed to identify the source over 18 months.

P300 Result: 14 employees tested in 1 day on-site. Two employees showed strong P300 recognition responses to case-specific stimuli. Both subsequently admitted involvement when presented with the evidence.

Outcome: £340K loss stopped. Criminal prosecution initiated.

Financial Services — Data Breach

Insider Threat Identified in 4 Hours

Investment firm detected unauthorised access to client portfolio data. Digital forensics narrowed suspects to 8 employees with system access but could not determine who.

P300 Result: All 8 employees tested in a single afternoon. One employee's brain showed unmistakable recognition of the specific data extraction method used — information only the perpetrator would know.

Outcome: Insider identified. FCA regulatory requirements satisfied.

Manufacturing — IP Theft

Trade Secrets Leak Stopped

Engineering firm discovered proprietary designs appearing in a competitor's product. Internal investigation suspected 3 employees with access to the CAD files but lacked proof.

P300 Result: P300 testing presented stimuli containing the specific file names and transfer methods. One employee showed clear recognition. The other two were definitively cleared — protecting their careers and reputations.

Outcome: IP leak sealed. Civil litigation evidence secured. Two innocent employees vindicated.

Lie Detector vs Polygraph — Accuracy Comparison

Independent research consistently shows P300 EEG brain-wave analysis outperforms traditional polygraph across every key measure.

Sources: Farwell & Donchin (1991), Rosenfeld et al. (2008), peer-reviewed EEG literature.

What the Readings Actually Look Like

The P300 brain-wave spike is a single, unmistakable response. Polygraph produces four overlapping signals full of noise — see why P300 EEG results are so much clearer to read.

✓ One clear spike — unambiguous result

Corporate Lie Detector Testing FAQ

Corporate P300 EEG testing starts from £499 per employee for the Starter Package (5–10 employees). Business packages (11–25 employees) drop to £449 per person, and Enterprise packages (26+) to £399. All prices include on-site deployment, individual testing, detailed PDF reports, and a corporate summary dashboard. Volume discounts and framework agreements are available for ongoing programmes.

Yes. Our portable 8-channel BrainBit EEG system requires only a quiet room and a laptop. We regularly deploy on-site at offices, warehouses, retail stores, and secure facilities across the UK. Each employee test takes approximately 15 minutes. We can screen 20+ employees in a single day with minimal disruption to operations.

Yes. Lie detector testing is legal in the UK for corporate investigations when conducted with informed consent. P300 EEG testing is non-invasive and measures brain activity only — no physical stress is induced. Results are increasingly accepted as supporting evidence in employment tribunals, disciplinary panels, and internal investigations. We provide GDPR-compliant data handling and full chain-of-custody documentation.

P300 EEG testing detects concealed knowledge related to any corporate issue: internal theft, inventory shrinkage, financial fraud, expense fraud, data breaches, intellectual property theft, bribery, corruption, unauthorised access, and employee misconduct. The test works by measuring whether the brain recognises case-specific information — if the person has knowledge they deny having, the P300 response reveals it.

P300 EEG achieves 95% accuracy versus polygraph's 65%. For corporate clients this matters because false positives destroy trust — polygraph wrongly accuses innocent employees 15–25% of the time. P300 EEG has a false positive rate below 5%. The test takes 15 minutes versus 2–4 hours for polygraph. Most importantly, P300 cannot be beaten through countermeasures — the brain's recognition response is involuntary and occurs within 300 milliseconds, faster than conscious control.

Yes — informed consent is required. However, in our experience, genuinely innocent employees volunteer for testing because they want to clear their name. Refusal itself is not evidence of guilt, but when offered alongside other investigation methods, most employees choose to participate. We provide pre-test consultation materials that HR teams can share with employees to explain the process and address concerns.
