1. Release of funds

An ISO 27001-implementation requires time, manpower and the right systems. It may seem like a challenge to free up those resources in addition to daily activities. But without this investment, you will not get sustainable compliance. Start small, make a plan and distribute tasks across teams. This way, you can quickly take concrete steps without completely shutting down your organization.

2. Wanting to finish too quickly

Many organizations want to obtain ISO certification “just as quickly”. The result? Processes and systems are not sufficiently thought out, which causes problems later. Implementing the ISO 27001 this becomes a checklist, where the system itself receives too little attention and organizations suddenly have to do everything they can to pass the audit at the end of the trip. And that can sometimes cause problems. So take the time to work thoroughly, even if you feel pressure to see results quickly. Rather take a little longer and do it well than be back to square one later.

3. Becoming dependent on external help

An external expert is of course a good option and it is tempting to let an external expert take care of everything. In fact, ISO 27001 also requires involvement from your own organization. External consultants will help you, but internal commitment remains necessary. Make sure your team actively participates and takes responsibility. This way, the knowledge remains in-house, even after the consultant has left.

4. Lack of management involvement

Without management support, it will be difficult to properly implement ISO 27001. Top management must understand why this standard is important and actively show their support. Not only in words, but also in freeing up resources and directing employees to take the right actions. Make sure management sees and continues to emphasize the importance, for example by:

  • making management the owner of certain risks;
  • one executive review to organize;
  • providing awareness training for board members.

5. Raising awareness across the organization

ISO 27001 isn't just about the IT department. Everyone in your organization must understand why information security is important and what their role is in it. This requires a well-thought-out awareness campaign. Think of training with the help of Guardey, emails and regular reminders to keep everyone on their toes.

6. Too much focus on technology

Especially in IT-driven organizations, you see that the focus is often on technology. However, ISO 27001 is not just about technical solutions. Policies, procedures and processes are just as important. So don't forget to pay attention to those “softer” aspects and make sure everything is in balance. In addition to 34 technological control measures (controls), there are also 37 organizational control measures, 8 people-centered control measures and 14 physical control measures — and these are just as important.

7. Lack of (correct) documentation

Many organizations have trouble documenting. Either there is too little documentation, or it is unclear exactly what needs to be documented. Good documentation is the backbone of your ISO 27001 system. Take the time to set this up properly and show how it offers added value. People need to understand that good documentation is not only an obligation, but actually helps to streamline processes and demonstrate compliance.

8. Translating policy into practice

Setting up policy is one thing, actually implementing it is another story. How do you ensure that the policy not only remains on paper, but is also complied with? By linking policy directly to the annual planning with controls and burden of proof, preferably in your task and project management system. This makes it concrete and feasible for your team to comply with the rules.

9. Overlooking legal and privacy

Information security also addresses legal and privacy issues. This is often forgotten, even though it is essential. Make sure you have or engage the right legal knowledge and that you also comply with privacy legislation, such as the AVG, included in your ISO 27001 system. For example, recording processing agreements and securing personal data.

10. ISO as “one person's party”

You often see that the Security Officer or Quality Manager takes full responsibility for implementing ISO 27001. The risk is that the rest of the organization will not be involved. ISO 27001 is an organization-wide project, not a solo project. Everyone needs to be included in the changes and understand their role.

Lastly

A successful ISO 27001 implementation requires engagement at every level, from management to executive staff. By taking time, recruiting the right people and focusing on both processes and technology, you put your organization on the map as a reliable partner in information security. Have you already taken steps or are you facing one of these challenges? Share your experience or ask for advice, we'd love to think along with you!
