ISO 27001 internal audit services
Client need
Internal audit as a mandatory requirement
Internal audits are a mandatory component of an ISO 27001-compliant Information Security Management System (ISMS). Organizations with ISO 27001 certification must conduct regular internal audits to maintain their certification and demonstrate continuous improvement.
Several of our clients had already achieved ISO 27001 certification but lacked the internal expertise or resources to conduct their own internal audits. Outsourcing the internal audit to Fraktal provided them with an independent, objective assessment while ensuring they met their compliance obligations.
Audit objectives
The internal audits were designed to address the following objectives:
- Ensure conformity to the requirements of ISO 27001:2022 across all normative clauses
- Verify control implementation and effectiveness based on selected Annex A controls
- Identify nonconformities, areas for improvement, and opportunities to strengthen the ISMS
- Evaluate whether the ISMS is fit for purpose, properly implemented, and maintained in accordance with ISO 27001
We delivered
Comprehensive audit process
Fraktal conducted thorough internal audits combining documentation review with stakeholder interviews. Our auditors examined ISMS documentation, policies, procedures, and records to verify that the management system met ISO 27001:2022 requirements.
We interviewed key personnel across the organization who demonstrated evidence of ISMS operation in practice. This combination of document review and interviews ensured we could assess both the design and operational effectiveness of the information security controls.
Clear findings and recommendations
As the outcome of each audit, the client received our assessment of whether their ISMS meets ISO 27001 requirements. The audit report included categorized findings, identified nonconformities, and practical recommendations for further developing the information security management system.
Our recommendations were prioritized to help clients focus their improvement efforts where they would have the greatest impact on their security posture and compliance status.
Our approach
Document review
We examined ISMS documentation including the scope statement, risk assessment methodology, Statement of Applicability, policies, procedures, and records of ISMS activities. This review verified that required documentation exists and aligns with ISO 27001:2022 requirements.
Stakeholder interviews
We conducted structured interviews with personnel responsible for information security across the organization. Interviewees demonstrated evidence of how controls are implemented and maintained in daily operations.
Control effectiveness assessment
Beyond verifying that controls exist, we assessed whether they are operating effectively. This included examining evidence of control activities, reviewing metrics and monitoring data, and evaluating incident response records.
Independent perspective
As external auditors, we provided an objective assessment free from internal biases. This independence is valuable both for identifying blind spots and for demonstrating audit impartiality to certification bodies.
Why this matters
Maintaining certification
Regular internal audits are essential for maintaining ISO 27001 certification. Our audit services help organizations meet this requirement without diverting internal resources from other priorities.
Continuous improvement
Internal audits are not just about compliance. They provide valuable input for the continuous improvement cycle that is central to ISO 27001. Our findings help organizations strengthen their ISMS over time.
Preparation for external audits
A thorough internal audit helps organizations identify and address issues before their certification body's surveillance or recertification audit, reducing the risk of nonconformities during external assessments.
