Beyond the Checklist: 7 Top ISO 27001 Audit Findings and How to Avoid Them
ISO 27001 Audit
For many organisations I’ve worked with, I’ve found that an ISO 27001 audit can be a source of anxiety and worries. But after years of working as a Lead Auditor, I’ve realized that most major Non Conformities don't actually stem from a lack of technology, but come from a lack of Risk Assurance culture.
If you are aware of the problems around your Information Security and suspect your ISMS is more of a paper shield than a digital fortress, then this list is for you. Here are the top seven findings that I see in the field and the strategic steps to avoid them.
The most common ISO 27001 audit findings rarely stem from technical failures. In most cases they arise from weak governance, outdated risk assessments, and poor evidence of compliance.
Enhancing ISO 27001 Audit Compliance
1. The Ghost Risk Assessment (Clause 6.1.2)
The Finding: So the risk assessment exists, but it’s effectively a static document that’s out of date. It doesn't reflect the current reality of the business, such as the shift to remote work or the integration of AI tools.
How to Avoid it: You should treat your risk assessment as a living ledger. Link it to your operational changes. If you implement a new IDAM solution for example, your risk assessment must be the first thing you update.
2. Management Review as a Tick Box Exercise (Clause 9.3)
The Finding: The minutes from management reviews that are one page long and show no evidence of critical thinking or resource allocation.
How to Avoid it: This is where my eMBA background comes in. I’ve found that Management reviews aren’t just a compliance hurdle, they should really be treated as a strategic pivot. Ensure your minutes reflect discussions on Risk Appetite and Return on Investment (ROI) for security spending.
3. The Policy Reality Gap (Access Control)
The Finding: The policy mentions that leavers are deactivated within 24 hours but the audit evidence shows accounts active weeks after departure.
How to Avoid it: Don’t write policies that your processes are unable to enforce efficiently. If your Joiner Mover Leaver (JML) process is manual, look to automate it. An auditor looks for the delta between what you say and what you do.
4. Internal Audits that are Too Nice Findings Wise (Clause 9.2)
The Finding: Internal audits that never identify weaknesses are often a warning sign that the process lacks independence or rigour. A structured approach to running an effective ISO 27001 internal audit ensures your organisation identifies weaknesses before the certification body does.
How to Avoid it: Hire an independent specialist to get amongst the weeds of your ISMS. An internal audit should be a stress test. If you don't find the cracks yourself, I promise the external auditor will, so prevention is so much better than cure here.
5. Lack of Evidence for Training & Awareness (Clause 7.2.2)
The Finding: The organisation as a whole says they’ve had security training, but there are no attendance logs, quiz scores, or evidence of culture checks provided.
How to Avoid it: Move beyond the once a year security awareness presentation. Use phishing simulations and micro learning modules that will provide a continuous data stream of employee competence to evidence to your auditor.
6. Vague Statement of Applicability (SoA) Justifications
The Finding: Controls are excluded from the SoA with the justification "Not Applicable," but with no explanation as to why (hint -the auditor needs to know ‘why!’).
How to Avoid it: Every exclusion must have a robust and risk based rationale. If you exclude physical security controls because you are 100% cloud-based, you still need to explain how you manage the security of the data centers you rely on.
7. The Open Loop on Corrective Actions (Clause 10.2)
The Finding: Incidents occur, they are recorded, but the Root Cause Analysis is missing or shallow, meaning the same issue happens again and again.
How to Avoid it: Close the loop. Don't just fix the problem; audit the reason it happened. I’d recommend using the “5 Whys” method to ensure that your corrective actions actually prevent recurrence and give you an underlying understanding of why it happened in the first place.
Strategic Insight: From Compliance to Risk Assurance
So the organisations that lead the pack in terms of their information security are the ones that stop viewing ISO 27001 as a defensive chore and start viewing it as a Risk Assurance framework.
When you align your security management with business objectives, you’re not just passing the audit, you’re actually building a resilient organisation that is ready to tender for major frameworks like the Cyber Security Services 3 DPS, for example. You’re also enabling continuous improvement and lowering your risk profile, which is definitely a win win for most businesses.
