An ISO Internal Audit should be more than a box‑ticking exercise. When it is well planned, independent and expertly delivered, it becomes one of the most powerful tools you have to sharpen performance, prove compliance and drive continual improvement across your organisation.
Anitech provides comprehensive internal audit services for ISO 9001, ISO 14001, ISO 27001, ISO 45001 (including ISO 45003), food safety and hazardous‑substance requirements. Their experienced auditors combine deep process assessment, agile audit techniques and advanced analytics to give you clear, actionable insights that move your organisation forward.
What Is an ISO Internal Audit?
An ISO internal audit is a systematic, independent and documented process for obtaining audit evidence and evaluating it objectively to determine how far your management system meets defined criteria, such as ISO standards, your own procedures and legal obligations.
It is a formal requirement of all ISO management system standards and acts as a regular health check on your systems. Done well, internal audits help you to:
- Verify compliance with ISO requirements, legal obligations and internal policies.
- Identify non‑conformities and weaknesses before they result in incidents, customer complaints or regulatory findings.
- Streamline processes by revealing bottlenecks, duplication and unnecessary complexity.
- Uncover improvement opportunities that enhance quality, safety, security and environmental performance.
- Prepare confidently for external certification audits and surveillance visits.
ISO standards require internal audits to be performed at planned intervals. Best practice is to audit each core process at least annually, increasing the frequency for high‑risk activities, areas where changes have occurred or where earlier audits uncovered significant non‑conformities.

Anitech’s Three‑Pillar Audit Methodology
Anitech’s internal audit methodology is designed to uncover meaningful insights while staying agile and minimally disruptive. It is built on three core pillars.
1. Deep Process Assessment
Auditors work to understand how your processes operate in reality, not just how they are described on paper. This includes:
- Mapping process flows and information paths end‑to‑end.
- Engaging with people at different levels to understand roles and pain points.
- Reviewing records and objective evidence to confirm consistency.
2. Agile Audit Techniques
Rather than a rigid, one‑size approach, Anitech uses agile methods that allow for flexibility and quick feedback loops, such as:
- Adjusting audit focus as new risks or findings emerge.
- Providing interim feedback so issues can start to be addressed promptly.
- Iterative improvements to your audit program over time based on results and lessons learned.
3. Advanced Analytics and Insight
Leveraging analytical tools and techniques, Anitech turns audit observations into meaningful insights by:
- Identifying patterns among non‑conformities, near misses and performance data.
- Highlighting systemic issues that cut across multiple processes or sites.
- Prioritising findings based on risk, impact and effort to fix.
This structured methodology ensures that internal audits lead to focused actions, not just long lists of observations.
How Often Should ISO Internal Audits Be Conducted?
ISO standards such as ISO 9001, ISO 14001, ISO 27001 and ISO 45001 all state that internal audits must be conducted at planned intervals. While they do not prescribe an exact frequency, a practical best‑practice model is:
- Audit each process or functional area at least once per year.
- Increase frequency for high‑risk processes or critical controls.
- Schedule additional audits when there are significant changes such as new systems, restructures or regulatory shifts.
- Follow up more frequently where serious non‑conformities were previously identified.
Anitech can work with you to design a risk‑based internal audit program that meets ISO expectations while aligning with your resources and priorities.
| Area | Typical Baseline Frequency | When to Increase Frequency |
|---|---|---|
| Core management system processes | Annually | Following major changes or repeated non‑conformities |
| High‑risk operations or sites | Annually | Where risk exposure is high or incidents occur |
| Information security controls (ISO 27001) | Annually, risk‑based | After system changes, new threats or significant incidents |
| Environmental aspects with significant impacts (ISO 14001) | Annually | If new legal requirements or operational changes arise |
| Health and safety controls (ISO 45001 / 45003) | Annually | After serious incidents, near misses or process changes |
The ISO 27001 Internal Audit Process in Practice
While each engagement is tailored, the ISO 27001 internal audit process typically follows four key stages.
- Planning
- Define audit objectives, scope and criteria based on your ISMS, risk assessment results and Statement of Applicability.
- Prepare an audit plan covering processes, locations, timeframes and key contacts.
- Conducting the audit
- Review documentation such as policies, procedures, risk assessments and incident records.
- Interview staff at different levels to test awareness and practical implementation.
- Observe processes and, where appropriate, sample technical controls.
- Reporting findings
- Record non‑conformities against ISO 27001 requirements and your own procedures.
- Highlight observations and improvement opportunities that strengthen the ISMS.
- Present a clear, structured report with prioritised actions.
- Corrective‑action follow‑up
- Agree corrective and preventive actions, responsibilities and timeframes.
- Verify that implemented actions are effective and sustainable.
Anitech’s auditors guide you through each step, so your information security team gains both assurance and practical insights into how to keep improving.
