ISO 27001 Implementation
Build an information security management system compliant with the international standard, from initial analysis to certification.
What is an ISO 27001 implementation?
ISO 27001 implementation involves building an information security management system (ISMS) compliant with the international standard, from initial analysis to preparation for the certification audit.
ISO 27001 provides a recognised framework for protecting the confidentiality, integrity and availability of information. It relies on a risk-based approach and requires the implementation of 93 security controls structured in Annex A. Certification demonstrates to your clients, partners and regulators that your organisation manages information security according to international best practices.
Implementation also serves as a regulatory compliance accelerator: an ISO 27001 certified organisation already has much of the foundation needed to meet NIS2, DORA or GDPR requirements.
Our team holds the ISO 27001 Lead Implementer certification, ensuring full mastery of the standard and its requirements throughout the implementation process.

How do we proceed?
The engagement follows a structured four-phase approach, from initial assessment to certification audit preparation.
Analysis and scoping
Comprehensive assessment of your security posture against ISO 27001 requirements and the 93 Annex A controls. Review of existing documentation, interviews with key stakeholders, identification of critical business processes and mapping of information assets. Definition of the ISMS scope and work planning.
ISMS construction
Building all ISMS components: risk analysis via the MONARC platform, drafting security policies and procedures, defining roles and responsibilities, implementing Annex A controls. Each deliverable is built in collaboration with your teams.
Certification preparation
Complete ISMS review to verify that all standard requirements are met. Internal audit, management review preparation and evidence file compilation. Preparing teams for interviews with the certification body.
Continuous improvement
Certification is not an end in itself. Support in maintaining the ISMS: risk analysis updates, annual reviews, surveillance internal audits and scope evolution as the organisation grows.
Prerequisites
Management commitment to the certification process. Existing documentation: policies, procedures, asset inventories, previous audit results. Access to key stakeholders: management, business owners, IT and security teams. Definition of the target ISMS scope. A dedicated client-side contact for engagement oversight.
Critical infrastructure
Extending ISO 27001 certification across the full scope of a Belgian critical infrastructure operator
A Belgian critical infrastructure operator had been ISO 27001 certified on part of its scope for several years. One of our partners has supported this organisation since the beginning of its certification journey, ensuring continuity and deep knowledge of its environment.
The organisation decided to extend certification to its entire scope for 2026. Ongoing work covers analysis of the expanded scope, risk assessment updates via MONARC, drafting additional policies and procedures, and preparing for the certification audit planned later this year.
Beyond certification, this initiative also enables the organisation to lay the foundations for compliance with the NIS2 directive, to which it is subject as a critical infrastructure operator.
A concrete example of how ISO 27001 certification can serve as a springboard towards regulatory compliance.
