ISO 27001 vs NIS2 and DORA: Does Certification Cover You?

Where Overlap Is Strong

• Risk management and governance (Clauses 5–6)
• Incident handling processes and evidence (A.5 incident controls + operations)
• Supplier security and ICT third-party oversight themes
• Logging, monitoring, and continuity-related technological controls

Where You Still Need More Than a Certificate

• Entity classification and competent-authority reporting under NIS2
• DORA-specific ICT incident classification, TLPT, and contractual registers
• National transposition nuances and sector regulators

Frequently Asked Questions

Does ISO 27001 equal NIS2 compliance?

No. NIS2 is law with entity scope, reporting, and governance duties. ISO 27001 certification is strong evidence of an ISMS but does not automatically discharge every NIS2 Article obligation.

Does ISO 27001 equal DORA compliance?

No. DORA imposes ICT risk, incident, testing, and third-party requirements on in-scope financial entities. ISO 27001 helps the management-system backbone; DORA still has sector-specific mandates.

Should EU firms still pursue ISO 27001?

Often yes — buyers and boards recognize it, and it maps cleanly to many security control expectations — alongside a NIS2/DORA obligation register.
