In national security and intelligence contexts, the threat is rarely visible. It is concealed in false identities, undisclosed affiliations, hidden knowledge of planned activity, or deceptive narratives.
Often the people who represent the greatest threat are also the most motivated and capable to hide it. Interviews can be prepared for. Background checks only reveal what records contain.
EyeTrek tests for concealed information directly, not by asking questions, but by measuring how the brain responds to images and text. It does not rely on verbal answers, stress responses to questioning, or examiner interpretation. Suppression attempts are easy to detect.
In addition to concealed knowledge detection, EyeTrek can evaluate responses to direct screening questions such as “have you ever?”
