Providing Truth Tests All Over the UK.

When Polygraph Security Services was incorporated in 1982 it was, to all intents, an extension of the Zonn Corporation of America whose well established Institute of Polygraph Inc trained all our operatives including Jeremy Barrett our Managing Director.

The Zonn Corporation, established in 1947, had offices in 14 cities in USA, and was one of the largest of many American companies specialising in Polygraphy and all aspects of lie detection.

They provided an invaluable service to thousands of companies ranging from corner drugstores to multinational corporations.

Apart from our own operatives, Zonn trained literally thousands of Police, Military and civilian personnel in the science of the Polygraph.

Thus, at the start of the new millennium, Polygraph Security Services offers you a service based on more than half a century of Truth Testing.
