Employee Polygraph Screening
Employee polygraph screening for your existing team — voluntary internal investigations into theft and shrinkage, data or IP leaks, and specific workplace incidents. Consent-based, discreet and evidence-focused, delivered in 40+ countries, online or with an examiner on site.
In short: employee polygraph screening is a voluntary examination of current staff — usually tied to a specific incident such as theft, a leak or a loss — taken with each person's written consent. It narrows an investigation to the facts and is used for the employer's own decisions, not as court evidence.
What employee polygraph screening is for
When something has gone wrong and several people had access, testing the relevant few — with their agreement — helps separate those involved from those who aren't, often within a day or two.
A voluntary examination just as often clears people as implicates them, taking the pressure and suspicion off staff who had nothing to do with the matter.
The result is a documented, objective input for an internal decision — far more solid than acting on rumour, and handled under a mutual NDA where needed.
Situations it covers
Cash going missing, stock loss, unrecorded transactions in retail, hospitality, warehousing and distribution.
Customer records, deal information or source code reaching a competitor. Testing the short list of people who held access.
Grievances and disciplinary matters that turn on conflicting accounts, and suspected fraud among managers or partners.
Screening can also be periodic rather than incident-driven — a scheduled, voluntary check for staff in especially sensitive positions, agreed as part of the role. In every case the questions are focused on the specific matter and agreed in advance; we don't run open-ended fishing exercises.
How an internal screening runs
What you get, and what we won't do
- A confidential review of the incident, free of charge
- A tightly scoped question set focused on the matter
- Voluntary written consent from each person tested
- A mutual NDA where the client wants one
- On-site testing for the team, or remote where suitable
- A written report per examinee, plus a verbal debrief
- Test anyone who hasn't consented in writing
- Treat a refusal to take the test as proof of guilt
- Ask open-ended questions unrelated to the incident
- Provide a document for use as court evidence
- Force a verdict where responses are inconclusive
- Disclose results beyond the people you nominate
Consent, employment law and privacy
Screening existing staff is a sensitive step, and we run it strictly within a consent-first framework. The key points:
- Every examination is voluntary and requires the employee's written, informed consent, which can be withdrawn at any time. A refusal to take a test is not, on its own, a lawful ground for dismissal or discipline
- Polygraph results are not admissible as court evidence in most jurisdictions; the screening supports the employer's internal decisions and, where relevant, a wider investigation — it isn't proof at trial
- Employment rules differ across Europe and the UK, and some countries place specific conditions on when and how workplace testing may be used. We work within the local rules wherever you are and advise employers to take their own advice before proceeding
- Personal data is processed under the applicable privacy law (UK/EU GDPR, PIPEDA and others): a defined purpose, consent, secure storage and access limited to a named few
- Findings are released only to the people the employer nominates and are never shared more widely without written consent
Staff screening is priced per examination by format and location — from $205 online and from $250 in person — with a discount when several people are tested and a bespoke rate for a full workforce screening. A second test language adds about $95. The complete breakdown is on our pricing page.
What clients say
"Persistent stock loss we couldn't trace. They tested the management and till staff by consent and found the weak link. It resolved months of uncertainty."
"A leaked database and two people in the frame. The voluntary test cleared both — the source was outside the team. It narrowed the search and eased real tension."
"A confidentiality breach in a small team. Handled with consent and under an NDA, entirely discreet. We could decide on evidence rather than suspicion."
"Takings didn't add up across venues. The examiner came on site and tested the key staff over a day. Scheduling took some coordination, but it did the job."
Employee polygraph screening explained
When money goes missing, information leaks or an incident divides a team into conflicting accounts, an employer is often left choosing between acting on suspicion and doing nothing. Employee polygraph screening offers a third path: a voluntary, consent-based examination of the people genuinely connected to the matter, focused tightly on what happened. Used well, it narrows an internal investigation quickly — and just as importantly, it clears the staff who had nothing to do with it, lifting a cloud that can otherwise hang over a whole department.
The work is deliberately contained. We scope the enquiry with you confidentially, agree a question set that stays on the specific incident, and obtain each participant's written consent before anyone is tested. On a group matter our examiner attends your premises with the full equipment, working from a private room; single cases can often be handled online. Every person receives a written report, and you get a verbal debrief on the findings — all under a mutual NDA where the situation calls for one.
It's important to be clear about what screening is and isn't. It supports an employer's internal decision-making; it is not evidence for a courtroom, and it is never a licence to interrogate. Consent is the foundation — a refusal is not treated as guilt — and workplace-testing rules vary across Europe and the UK, so we keep every engagement inside the local rules wherever it takes place. That makes the process sound as well as useful.
