ISO 27001 – Internal Audit
Internal audit in short
Internal auditing in accordance with the ISO 27001 standard is an essential part of maintaining and developing an organisation’s information security management system (ISMS). The purpose of the audit is to ensure that the ISMS meets the requirements of the standard, to identify any deviations, and to provide recommendations that support continuous improvement.
Organisations must carry out internal audits at planned intervals in order to assess and ensure that the management system is effectively implemented and maintained. Each organisation is responsible for defining whether the entire management system and all controls will be audited at once, or whether the scope will be divided across multiple years.
Mint Security’s audit service is tailored to support these needs. The audit is conducted independently, at an administrative level, and is based on a review of documentation and interviews with key personnel.
What Mint Security delivers
Mint Security offers ISO 27001 internal auditing as a service, covering the entire audit process from planning to reporting.
The service includes:
- Audit planning and scheduling
- Interview framework
- On-site audit visit, including a tour of the premises, or remote audit
- Review of documentation
- Audit report presenting findings, references to the standard, and recommended actions
The audit schedule and interviews are based on the chapters of the ISO 27001 standard and the operational capabilities of the Annex A controls. During interviews, best practices for implementing the controls can also be discussed.
Our audit report complies with the requirements of the standard and includes:
- Audit criteria, methods, and scope
- Audit schedule and list of participants
- Observations and recommendations
- References to relevant clauses in the standard
- Classification of findings: major nonconformity, minor nonconformity, observation/recommendation
- Supporting evidence
The internal auditor provided by Mint Security is always certified – holding either the ISO 27001 Lead Implementer or ISO 27001 Internal Auditor qualification.
Customer needs and challenges to be solved
Organisations may face various challenges during ISO 27001 audits, such as:
- Lack of auditing expertise or the requirement for independence
- Fragmented or incomplete documentation
- Difficulties in applying controls in practice
- The need for external perspective and development suggestions
While conducting internal audits in-house can be cost-effective and leverage internal process knowledge, it does not always ensure objectivity or sufficient expertise. Engaging an external auditor can bring added value—especially when there is a need for an impartial assessment, broader insight into industry best practices, or a desire to ensure the audit’s impact without internal tensions.
Mint Security addresses these needs by offering a knowledgeable, transparent, and systematic audit service that supports an organisation’s certification journey and the ongoing development of information security—whether it’s the first audit or part of continuous improvement.
