The book examines insider threats from a psychometric, psychophysiological, legal, and operational perspective. In contrast to conventional interviews, remote questionnaires, and automated screening systems that remain vulnerable to faking good strategies, the author presents a two-stage model that combines the Psychometric Profile of Integrity and Examination (PPIE) with in-person polygraph validation. This approach transforms critical personnel assessment into a forensic triage process capable of identifying extreme defensiveness, inconsistencies, moral rationalizations, critical risk indicators, and signs of concealment before an individual gains access to strategic information, assets, or responsibilities.

Written in a practical and highly applied style, the manual explores the architecture of the PPIE system, its concealed assessment scales, environmental administration protocols, international legal safeguards, integration with techniques such as LEPET, DLST, AFMGQT, and UTAH, as well as a series of real-world case studies demonstrating its effectiveness in corporate, law enforcement, financial, and governmental environments.

More than a book about personnel selection, this work is a guide to preventive counterintelligence applied to the human factor. Its value lies in providing examiners, security managers, human resources executives, expert witnesses, auditors, and critical organizations with a structured methodology to protect themselves against fraud, infiltration, sabotage, corruption, and institutional betrayal before irreversible damage occurs.
