The Zenith Blueprint is a structured 30-step methodology designed to help small and mid-sized organisations build practical, evidence-driven security governance aligned with ISO/IEC 27001:2022. It integrates organisational, technical, and operational measures into a single, actionable roadmap suitable for early-stage ISMS programmes as well as maturing environments. This Research Edition consolidates the conceptual framework behind Clarysec’s compliance methodology, offering a clear sequence of activities that map to critical ISO 27001 domains, including risk management, asset governance, access control, incident readiness, operational planning, supplier security, and continuous improvement. The Blueprint reflects applied experience from industrial systems, cyber-physical environments, and multi-framework alignment across ISO 27001, NIS2, DORA, GDPR and NIST. It is intended for researchers, students, practitioners, and organisations exploring structured approaches to compliance, security governance, and operational resilience.
