Trust No One: Counterintelligence and the Rise of Zero Trust IAM

By Tony Adjuder

The greatest threat to your organization is already inside.
They have credentials. They pass every audit.
And they’re about to burn everything to the ground—from behind your firewall.

In this bold fusion of cyber thriller and real-world expertise, Trust No One uncovers the hidden war being waged inside your systems—by insiders, imposters, and adversaries who know exactly how to exploit trust. Packed with true stories, sharp analysis, and a gripping narrative voice, this book pulls from the shadowy world of espionage to reveal why identity is the new battlefield.

Author Tony Adjuder is no stranger to betrayal.
With years of experience supporting counterintelligence operations and insider threat programs for global enterprises and government contractors, Adjuder has seen firsthand how even the best organizations fail to detect traitors in their midst. His work has spanned threat modeling, IAM architecture, red team deception planning, and digital espionage countermeasures. What he discovered led him to a simple, chilling conclusion:

Trust is a vulnerability. Zero Trust is survival.
