Helping an Organization Prepare for ISO 27001 Certification

Iterise Consulting engaged us to perform an independent internal audit of its Information Security Management System (ISMS) to assess its readiness for ISO/IEC 27001:2022 certification. The objective was to evaluate the effectiveness of the organization's ISMS, verify alignment with the standard, identify nonconformities and provide a clear roadmap for achieving certification.

The Challenge

Iterise Consulting had established the core components of an Information Security Management System and sought an independent assessment before progressing toward ISO/IEC 27001 certification. The organization wanted assurance that its management system aligned with the standard while identifying any gaps that could affect a successful certification audit. The review focused on both governance and operational controls to ensure the ISMS was not only documented but also effectively implemented.

Our Approach

The engagement followed a structured, risk-based audit methodology aligned with ISO 19011 and ISO/IEC 27001:2022.
