The Next Identity Crisis

Autonomy, Power, and Control in the Age of AI

The Next Identity Crisis asks the question what happens to human identity when the systems we build stop being tools and start being actors? Where AI Identities offered a governance framework for enterprise practitioners, this book operates on a different register entirely. It is a philosophical examination of the deepest disruption of our time, written for anyone trying to make sense of a world that is shifting beneath their feet.

Structured around five interconnected crises (Identity, Ownership, Trust, Control, and Meaning), the book traces how autonomous AI has crossed from automation into agency, creating a new class of actor that our institutions were never designed to accommodate and triggering a cascade of consequences that touches everything from how we verify one another to how we understand ourselves.

This is not a book of strategy or implementation. It is an attempt to unsettle readers productively, to help them see the ground they are standing on and understand how it is moving. Written for the general reader, the business leader, the policymaker, and the philosopher alike, The Next Identity Crisis ends not with a checklist but with the questions that, once seen clearly, cannot be unseen.

AI Identities

Governing the Next Generation of Autonomous Actors

AI Identities introduces a groundbreaking concept: AI Agents should be recognized and governed as a new class of identity within enterprise environments. As artificial intelligence evolves from predictive models to autonomous agents with memory, goals, and tool access, enterprises face a new spectrum of identity risk that transcends traditional IAM frameworks. This book lays out the philosophical, architectural, and operational foundations necessary to govern these intelligent machine identities across their lifecycles. Structured across six parts, the book begins by grounding readers in identity security and ownership.

It then introduces the concept of AI agents as complex, evolving identities that demand governance, not just access control. It offers practical guidance on lifecycle management, trust, discovery, and incident response for AI agents, and concludes with future-facing perspectives on human-AI collaboration, critical infrastructure, and compliance.

Making Sense of AI

A Practical Guide to Capabilities, Limitations, and Real-World Impact

How does AI produce a convincing answer, and how much should we trust it? Making Sense of AI explains how large language models work in language nontechnical readers can understand. Drawing on research, real-world cases, technological history, and familiar stories from popular culture, Rosario Mastrogiacomo explores where AI is useful, why it fails, and how it is changing work. He examines the gap between completing a task and replacing a role, and asks what meaningful human oversight actually requires. The goal is to help readers make better-informed decisions about the technology they use.

Coming Spring 2027

Beyond the Hype Cycle

A Leader's Guide to Making AI Work in the Real World

Putting AI to useful work starts with a clear assignment and a person who remains responsible for the result. In Beyond the Hype Cycle, Rosario Mastrogiacomo offers practical methods for setting boundaries, reviewing results, and learning through use. He applies these ideas to research, writing, analysis, and personal AI agents, alongside the decisions leaders face about cost, trust, and performance. His Fail-Safe approach asks readers to plan for mistakes and limit their consequences. The book helps individuals and organizations use AI more effectively while recognizing when a simpler approach would serve them better.

About Rosario

Identity security.
AI-driven governance.

My professional journey has included leadership roles at prominent financial institutions, such as Barclays, Lehman Brothers, and Neuberger Berman, where I honed my skills in complex, highly regulated environments. I regularly publish insights on cybersecurity trends through my blog and host the podcast “Smells Like Identity Hygiene,” dedicated to exploring advanced topics in identity security and AI-driven governance.

I am the author of AI Identities: Governing the Next Generation of Autonomous Actors (Apress, 2025), which explores the strategic, operational, and ethical challenges of securing AI-driven identities and offers a framework for CISOs and architects to govern them effectively. My second book, The Next Identity Crisis: Autonomy, Power, and Control in the Age of AI (Apress, 2026), expands that conversation beyond the enterprise, examining how autonomous AI is reshaping the philosophical foundations of identity, trust, ownership, and what it means to be human in a world we no longer fully control.
