FAQ

Common Questions

Does ISO 27001 certification satisfy NIS2 requirements?

ISO 27001 certification provides a strong foundation but does not fully satisfy NIS2 requirements. NIS2 includes external reporting obligations and supply chain requirements that typically require additional processes and evidence beyond ISO 27001 alone.

Should I get ISO 27001 certified before NIS2 compliance?

If you're starting from scratch, pursuing ISO 27001 certification while incorporating NIS2-specific requirements can be efficient. Use the ISMS structure as a baseline, then add NIS2-specific elements like external reporting and supply chain requirements to complete your compliance.

What NIS2 requirements are not covered by ISO 27001?

Key NIS2 gaps beyond ISO 27001 include mandatory incident reporting to national authorities within strict timelines (24h early warning, 72h notification), explicit supply chain security obligations, management body personal liability provisions, and sector-specific requirements that vary by national transposition. FortisEU maps these gaps automatically.
