Feedback from our customers
Trust is built on honesty. Here you can read real stories from people who have undergone a polygraph test and shared their experiences.
We contacted you because of unexplained losses within the company. A polygraph examiner conducted tests on key staff members. The whole process was handled with great sensitivity and without any pressure. In the end, we managed to identify the person involved without damaging the working atmosphere within the team. It was money well spent.
I was falsely accused of theft at work, and my reputation was at stake. I insisted on taking a polygraph test myself to prove my innocence. The examiner explained everything in detail, and I felt hardly any stress. The report confirmed that I was telling the truth, and now I have an official document
We were looking for a nanny for our child through an agency, but decided to play it safe and carry out a background check. A polygraph examiner helped us draw up a list of questions about her previous experience and any hidden habits. This gave us a peace of mind that no number of reference letters could provide.
As an HR director, I used their services to conduct an internal investigation into a leak of confidential information. I was impressed by their discretion—the specialists arrived without any identifying badges, and the report was ready quickly and included a unique verification code. Very professional.
