Castle-and-moat security is dead. This book replaces it with Zero Trust Architecture and Structured Autonomy for agentic AI — NIST and CISA principles, EU AI Act risk tiers, human-in-the-loop escalation, and GDPR Article 22 governance — and hands CTOs and enterprise architects the complete toolkit to secure the borderless, AI-driven enterprise.

About the Book

Security Posture — Zero Trust, GDPR, and Ethical AI Governance is the fifth volume of The Agile Enterprise Playbook, a five-book series built on the FOCUS Methodology — an execution-oriented framework for CTOs, enterprise architects, and technology leaders navigating the Gen AI era under GDPR, the EU AI Act, NIS2, and DORA.

Castle-and-moat security is dead. As the network perimeter dissolves and Agentic AI assumes autonomous execution, traditional boundary-based defense is deeply flawed — every user, service, and agent must now be authenticated, authorized, and audited continuously. This book shows how to secure the modern, borderless enterprise against the backdrop of Europe's stringent regulatory environment, giving you the full toolkit to execute:

  • Zero Trust Architecture built on NIST and CISA principles
  • Continuous authentication, microsegmentation, and dynamic least privilege
  • Structured Autonomy for Agentic AI with the risk tiers mandated by the EU AI Act
  • Mandatory human-in-the-loop escalation for high-risk AI systems
  • Ethical impact assessments and algorithmic bias audits that keep automated decision-making compliant with GDPR Article 22

Written for practitioners in or trading with the EU, this is not a theoretical manifesto. Each chapter pairs the theory with a step-by-step methodology and real-world executions — from GenAI customer support agents to fintech scale-ups — so you can replace the castle-and-moat with a Zero Trust posture in which agentic AI acts under control: trusted, audited, and compliant by default.

About the Author

Agile Enterprise Media ApS

Lars Shakya Buch-Jepsen is a coding software, ai and data architect with more than 20 years of hands-on experience across enterprise architecture, data warehousing, integration, and cloud engineering. He has served as CTO, enterprise advisor to CTO offices, and today leads the technical branch of DevX, AI & Data at Aeven, helping regulated industries adopt AI, data services, and DevOps under strict compliance regimes.

The FOCUS Methodology was born from years of friction: Enterprise Architecture that was outdated the moment it was written, governance that stopped delivery instead of enabling it, or no architecture function at all — leaving teams to improvise. This book series is the how-to playbook he wished existed: the frameworks, worksheets, and decision workflows to run technology effectively in the age of GenAI, without failing compliance.
