NIS2 Directive – Cybersecurity for Essential and Important Entities
The NIS2 Directive establishes a common high level of cybersecurity across the European Union, extending obligations to a wider range of “essential” and “important” entities. For organisations in the NIS2 perimeter, an ISO/IEC 27001 certified Information Security Management System (ISMS) is a powerful framework to structure risk management, policies and incident handling in line with regulatory expectations.
- Broadened scope of entities compared to the original NIS Directive.
- Stronger requirements on governance, risk management and incident reporting.
- Directors’ accountability and stricter supervisory powers and sanctions.
Who Is Covered by the NIS2 Directive?
NIS2 applies to a wide range of essential and important entities that provide services critical to the economy and society. If your organisation falls under NIS2, aligning with ISO/IEC 27001 helps translate regulatory expectations into concrete policies, controls and responsibilities.
Essential services
Operators whose disruption would have a significant impact on the functioning of the economy or society. For these entities, ISO/IEC 27001 supports a structured cybersecurity governance model aligned with NIS2.
- Energy (electricity, gas, oil, district heating).
- Transport (air, rail, road, maritime).
- Banking and financial market infrastructures.
Digital and ICT infrastructures
Key digital actors that support connectivity and online services across the EU. An ISO/IEC 27001 ISMS provides the backbone for security policies, controls and incident management required by NIS2.
- DNS providers and top-level domain name registries.
- Cloud computing services and data centres.
- Content delivery networks and trust service providers.
Public administration and health
Public sector entities and healthcare providers must ensure continuity and security of services that are vital for citizens. ISO/IEC 27001 supports information security, risk management and incident response processes.
- Central and regional public administration.
- Hospitals and healthcare providers.
- Drinking water suppliers and distributors.
Important entities
NIS2 also covers a wide group of “important entities” whose services are relevant for the economy and society, with obligations that are proportionate but still significant.
- Manufacturing of critical products.
- Postal and courier services.
- Waste management and food supply chain operators.
Supply chains and service providers
NIS2 puts strong emphasis on supply chain security. Even if you are not directly classified as an NIS2 entity, your customers may require evidence of robust information security, where ISO/IEC 27001 certification is often a key element.
- IT and OT service providers.
- Managed security and monitoring providers.
- Specialised suppliers in critical sectors.
Key Elements of NIS2 Cybersecurity Requirements
NIS2 sets out a comprehensive set of cybersecurity requirements that cover governance, technical and organisational measures, incident handling and reporting. Many of these elements can be integrated into an ISO/IEC 27001-certified ISMS, which provides a structured approach to documentation, implementation and continuous improvement.
Why ISO/IEC 27001 Is Strategic for NIS2 Compliance
From legal obligations to a structured ISMS
NIS2 describes what entities must achieve in terms of cybersecurity and risk management, but it does not prescribe a detailed management system. ISO/IEC 27001 fills this gap, offering a well-established framework for designing, implementing and maintaining an ISMS that integrates NIS2 requirements.
- Aligns legal requirements with policies, procedures and controls.
- Creates a central framework for risk assessment and treatment.
- Supports continuous improvement and regular reviews by management.
Evidence and trust for authorities and stakeholders
Demonstrating compliance with NIS2 requires documentation, monitoring and evidence that measures are effective. ISO/IEC 27001 certification by an independent body strengthens the credibility of your approach in the eyes of authorities, customers and partners.
- Independent evaluation of your information security management system.
- Structured documentation and records that support audits and inspections.
- Signals a mature, risk-based cybersecurity posture to the market.
How Our Certification Body Supports NIS2-Aligned ISO/IEC 27001
As a certification body authorised by EIAC in the United Arab Emirates, we issue ISO/IEC 27001 certificates recognised at international level. For entities impacted by NIS2, we focus our assessments on how your ISMS supports cybersecurity risk management, governance and incident handling in line with the directive.
Context and scope analysis
We start from your organisational context, services and regulatory perimeter, looking at how NIS2 requirements are reflected in your ISMS scope, risk assessment and security controls.
ISO/IEC 27001 certification audit
Through Stage 1 and Stage 2 audits, we assess whether your ISMS effectively manages information security risks, including those aspects directly relevant to NIS2, such as incident management, business continuity and supply chain security.
Surveillance and continual improvement
During surveillance audits, we verify that your ISMS continues to evolve in line with NIS2, reflecting changes in services, technologies, threat landscape and regulatory expectations.
NIS2 & ISO/IEC 27001 – Frequently Asked Questions
Below you can find answers to common questions on how the NIS2 Directive interacts with ISO/IEC 27001 and why a certified ISMS is particularly valuable for essential and important entities.
No. NIS2 does not explicitly require ISO/IEC 27001 certification. However, it mandates that entities implement appropriate and proportionate technical, operational and organisational measures to manage cybersecurity risks.
ISO/IEC 27001 provides a widely recognised framework to organise these measures in a coherent management system. Many organisations choose certification to demonstrate maturity and to support their dialogue with authorities, clients and partners.
NIS2 requires a risk-based approach to cybersecurity, with governance and processes that ensure risks are identified, assessed and mitigated. ISO/IEC 27001 is built on the same principles, with defined steps for context analysis, risk assessment, treatment and review.
By adopting ISO/IEC 27001, you can map NIS2 risk-related obligations onto a structured ISMS that provides clear responsibilities, controls and monitoring.
NIS2 introduces detailed obligations for reporting significant incidents to competent authorities and CSIRTs within specific timeframes. ISO/IEC 27001 does not replace legal requirements, but it provides a framework for incident management processes, roles, communication flows and records.
Embedding NIS2 reporting processes into your ISMS helps ensure that incidents are detected, assessed, escalated and documented consistently.
NIS2 explicitly requires entities to address cybersecurity risks in their supply chains and supplier relationships. ISO/IEC 27001 includes specific controls on supplier security that cover risk assessments, contractual requirements and monitoring.
Some entities also require key suppliers to be ISO/IEC 27001-certified, as additional assurance that their practices have been independently audited.
Our role as an independent certification body is to assess whether your ISMS is effectively designed and implemented in accordance with ISO/IEC 27001. During audits, we pay particular attention to areas that overlap with NIS2, such as governance, risk management, incident handling and supply chain security.
The resulting certification, issued under EIAC authorisation, supports your ability to demonstrate cybersecurity maturity and NIS2 alignment to authorities and stakeholders.
