ISO/IEC 27001 enables organisations to establish an Information Security Management System (ISMS). Information assets have become one of the primary drivers of value creation for any organisation, and their protection is increasingly a board-level responsibility.
Key concept · Due Care
The demonstration that leadership has implemented the measures reasonably expected to protect the organisation's information assets. For a board of directors — particularly in light of recent European regulations such as NIS2 and DORA — this concept is one of the foundations of responsible governance and personal liability.
Managing information security risks strengthens organisational resilience — the capacity to absorb incidents, adapt and sustain operations — while transforming cybersecurity from a cost centre into a genuine driver of value creation.
Implementing an ISMS certified to ISO/IEC 27001 builds lasting reputational capital and contributes to the factors that condition an organisation's valuation. It opens new markets, reinforces trust among clients, investors, suppliers, partners and regulators, and constitutes a powerful competitive advantage.
Most ISO/IEC 27001 training programmes focus solely on the standard itself. My approach is different: ISO/IEC 27001 is the entry point of a much wider ecosystem of standards, methods and frameworks that together enable a genuine information security governance architecture.

ISO/IEC 27002 — Defence in depth
Essential for designing a genuine defence-in-depth strategy, selecting security controls adapted to the organisation's risk profile and building a coherent architecture — in conjunction with EBIOS Risk Manager and governance based on the three lines of defence model adopted by most large organisations.
ISO/IEC 27005 and EBIOS Risk Manager — Risk management
ISO/IEC 27005 provides the process framework for information security risk management. It operationalises the risk assessment and treatment requirements of ISO/IEC 27001 into a structured, repeatable and auditable framework. EBIOS Risk Manager — a method now recognised well beyond France, whose international version has contributed significantly to the evolution of contemporary practices — is an essential complement for organisations operating in complex environments.
ISO/IEC 27004 — Measurement and performance management
Governance cannot be managed without measurement. ISO/IEC 27004 provides the framework for building performance and efficiency indicators (KPIs), objectively measuring ISMS effectiveness, and embedding continual improvement into a structured performance management cycle.
ISO/IEC 27006, 27007 and ISO 19011 — Audit and certification
For professionals seeking audit expertise, this vision is complemented by ISO/IEC 27006, ISO/IEC 27007 and ISO 19011, covering respectively the requirements for certification bodies, the principles of ISMS auditing and the international guidelines for auditing management systems.
Regulatory environment — NIS2, DORA and beyond
The full picture positions ISO/IEC 27001 within its regulatory and normative environment — articulating it with NIS2, DORA, ISO 22301, ISO 31000, ISO/IEC 42001 and the other frameworks that structure organisational governance today.
This approach is grounded in operational experience acquired with major international groups, defence sector organisations, critical entities, higher education institutions, Big Four advisory firms and international training organisations. It draws on field practice developed in France and internationally — notably in Luxembourg and Scandinavia — with organisations operating under demanding governance, risk management and compliance requirements.
This diversity of environments allows international standards to be approached not as theoretical texts, but as governance instruments applied to varied operational contexts, with a perspective firmly oriented towards value creation.
ISO/IEC 27001 only delivers its full value when understood as the foundation of a complete ecosystem for governance, risk management and value creation. That is the vision I transmit in every training programme I deliver.
