NIS2 vs. ISO 27001: Why Just ISO 27001 Is Not Sufficient
The new NIS2 directive sets stricter requirements for cybersecurity, and it affects your business¹ too. Many organizations still rely on ISO 27001, but it falls short in as many as 20 critical areas. This means that companies that don’t make a timely switch are at risk of fines, liability and non-compliance.
At ALTA-ICT, we take cybersecurity seriously. We are already pursuing certification for ISO 9001, ISO 27001 and NEN 7510 – so we not only meet the highest standards, but can also help your business stay secure and future-proof².
🛡️ Why is NIS2 important to your business?
As of Q3 2025, many companies must comply with NIS2 legislation. This means you must be able to demonstrate that you:
✅ Cyber threats actively managed 🛑
✅ Uses secure vendors and IT services 🔗
✅ Reports incidents within 24 hours ⏳
✅ Takes liability and audits seriously 📜
If you don’t take care of these issues now, you risk high fines and reputational damage.
⚠️ ISO 27001 vs. NIS2: 20 Crucial GAPs
Although ISO 27001 provides a strong foundation for information security, it falls short of NIS2 in at least 20 critical areas. This means that companies using only ISO 27001 are not in compliance with the new Cybersecurity Act.
📌 Examples of these GAPs:
🚫 No mandatory 24-hour incident reporting in ISO 27001
🚫 Insufficient focus on chain responsibility
🚫 No personal liability for directors
🚫 No explicit requirement for independent audits
Conclusion? Companies will need to take additional measures to fully comply with NIS2.
