The Digital Operational Resilience Act (DORA) has applied since January 17, 2025, creating binding digital operational resilience requirements for financial entities across the European Union. At the same time, many organizations already operate an information security management system based on ISO/IEC 27001:2022.
That raises an important question: can ISO 27001 help meet DORA requirements?
The short answer is yes, but only partially. ISO 27001 provides a strong foundation for information security governance, risk management, access control, supplier security, incident management, business continuity, and continuous improvement. However, DORA adds financial-sector-specific obligations that ISO 27001 does not fully address, including regulatory incident reporting, resilience testing, ICT third-party oversight, and specific contractual requirements.
This blog compares DORA vs ISO 27001, explains where they overlap, and identifies what financial entities still need to address for DORA compliance.
Key Takeaways
- DORA is a binding EU regulation for in-scope financial entities, while ISO/IEC 27001 is an international information security management standard.
- ISO 27001 can support DORA requirements related to ICT risk management, governance, incident management, supplier security, and business continuity.
- ISO 27001 certification does not automatically mean DORA compliance.
- DORA adds specific requirements for ICT incident reporting, resilience testing, ICT third-party risk, contractual arrangements, and regulatory oversight.
- Organizations already using ISO 27001 can build on existing controls, policies, risk processes, and evidence.
- A DORA-to-ISO 27001 gap assessment is still necessary.
What Is DORA?
DORA, formally Regulation (EU) 2022/2554, establishes uniform requirements for digital operational resilience in the EU financial sector. Its purpose is to ensure that financial entities can withstand, respond to, and recover from ICT-related disruptions while maintaining critical and important functions.
DORA covers a broad range of financial entities, including credit institutions, payment institutions, investment firms, insurers, crypto-asset service providers, and other regulated financial organizations.
Its requirements are commonly grouped into five core areas:
- ICT risk management
- ICT-related incident management and reporting
- Digital operational resilience testing
- ICT third-party risk management
- Information and intelligence sharing
DORA also addresses contractual arrangements with ICT third-party service providers and EU-level oversight of designated critical ICT providers.
What Is ISO/IEC 27001?
ISO/IEC 27001:2022 is an international standard that specifies requirements for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS).
It helps organizations manage information security risks through governance, risk assessment, policies, controls, monitoring, corrective actions, and continual improvement.
ISO 27001 is industry-neutral and can be used by organizations of different sizes and sectors. DORA, by contrast, is specifically focused on financial-sector digital operational resilience.
An ISO 27001-based ISMS can therefore provide much of the governance and control infrastructure needed to support DORA, but the scope and purpose of the two are different.

Can ISO 27001 Help Meet DORA Requirements?
Yes. ISO 27001 can reduce the work needed to build a DORA compliance program because many foundational governance and security processes may already exist within the ISMS.
An ISO 27001-certified organization may already have risk assessments, security policies, incident response procedures, access controls, supplier security processes, business continuity measures, audit records, and corrective-action workflows.
However, those controls still need to be mapped against DORA. ISO 27001 should be treated as a strong starting point, not as proof that every DORA obligation has been satisfied.
Where ISO 27001 Supports DORA Compliance
ISO 27001 can support several DORA requirements because both emphasize structured risk management, security controls, incident handling, supplier oversight, and continual improvement.
|
DORA Area |
How ISO 27001 Can Help |
|
ICT risk management |
Supports risk assessment, treatment, governance, policies, asset management, access control, and monitoring |
|
Incident management |
Provides processes for identifying, managing, and learning from security incidents |
|
Business continuity |
Supports resilience planning, backup, recovery, and continuity-related controls |
|
ICT third-party risk |
Includes supplier security, contractual requirements, monitoring, and external service management |
|
Testing and assurance |
Supports internal audits, control reviews, vulnerability management, and continual improvement |
Organizations with a mature ISO 27001 ISMS may therefore be able to reuse existing policies, controls, evidence, supplier reviews, and audit processes when building their DORA program.
Where ISO 27001 Is Not Enough for DORA
ISO 27001 provides a foundation, but several DORA obligations still require additional work.
1. Regulatory ICT Incident Reporting
DORA requires major ICT-related incidents to be classified and reported through defined regulatory processes and timelines. ISO 27001 supports incident management but does not reproduce DORA’s financial-sector reporting regime.
2. DORA Register of Information
Financial entities subject to DORA must maintain and update a Register of Information covering contractual arrangements for ICT services provided by ICT third-party providers. ISO 27001 supplier records do not replace this requirement.
3. Digital Operational Resilience Testing
DORA requires a structured digital operational resilience testing program. Certain financial entities must also conduct advanced Threat-Led Penetration Testing (TLPT). ISO 27001 supports security testing but does not by itself satisfy DORA’s testing regime.
4. ICT Third-Party Oversight
DORA adds detailed requirements for ICT third-party contracts, concentration risk, exit planning, and oversight of designated critical ICT third-party providers.

DORA and ISO 27001 Gap Assessment Checklist
Organizations already using ISO 27001 should:
- Map existing ISO 27001 controls and processes to DORA obligations.
- Identify critical functions and supporting ICT dependencies.
- Review incident classification and regulatory reporting procedures.
- Maintain the ICT third-party Register of Information.
- Review ICT contracts and exit requirements.
- Assess concentration and subcontracting risks.
- Establish required resilience testing and determine whether TLPT applies.
- Track gaps, remediation owners, and supporting evidence.
How Akitra Can Support DORA and ISO 27001 Readiness
Organizations managing both DORA and ISO 27001 need visibility into overlapping controls, evidence, risks, and remediation.
Akitra Andromeda® helps teams centralize compliance requirements, map controls across frameworks, automate evidence collection, monitor control status, and track remediation. This can help organizations reuse relevant ISO 27001 controls while identifying DORA-specific gaps that still require attention.
Conclusion
ISO 27001 can help meet DORA requirements, but it should be treated as a foundation rather than a substitute for DORA.
Organizations with an established ISO 27001 ISMS may already have many of the governance, security, incident-management, supplier-risk, and continuity processes needed to support DORA. They should then map those capabilities against DORA and address remaining requirements for reporting, resilience testing, and ICT third-party oversight.

FAQs
Does ISO 27001 certification prove DORA compliance?
No. DORA contains additional financial-sector obligations that must be assessed separately.
Which DORA requirements overlap most with ISO 27001?
Key overlaps include ICT risk management, security governance, incident management, business continuity, supplier security, access control, and continual improvement.
What are the biggest DORA gaps for ISO 27001-certified organizations?
Common gaps include DORA-specific incident reporting, the Register of Information, resilience testing, TLPT where applicable, and detailed ICT third-party requirements.
Should organizations map ISO 27001 controls to DORA?
Yes. Mapping helps identify reusable controls and evidence while making DORA-specific gaps easier to prioritize.
