Phase 3

Internal Audit

Overview

The Internal Audit phase is a critical component in preparing for the ISO 27001 certification audit. Its purpose is to independently verify that your Information Security Management System (ISMS) is functioning effectively and complies with ISO 27001 standards before undergoing the formal external certification audit. This phase involves conducting a comprehensive internal audit to evaluate the performance and effectiveness of your ISMS, identify any non-conformities, and determine areas for improvement. The internal audit serves as a proactive measure to address issues and ensure that your ISMS is fully prepared for the external audit, thus enhancing the likelihood of a successful certification outcome.
