## What is NIS 2?
NIS2 (Directive (EU) 2022/2555) is the EU's updated comprehensive cybersecurity law.
Aims to **significantly raise the baseline level of cybersecurity and resilience** across the European Union.
Focuses especially on **critical infrastructure and essential services**.
**Designed to protect the EUs economy and society** by making digital infrastructure more secure, resilient, and better prepared for evolving cyber threats.
---
# Goals
**Establish a unified, high standard of cybersecurity** for network and information systems in key sectors across all EU member states.
Strengthen cooperation and information sharing among member states for a **coordinated response to cross-border cyber threats**.
Promote consistency by **harmonizing security requirements, reporting obligations, and enforcement** across the EU.
Ensure organizations implement **robust risk management**, **incident response**, and **business continuity measures**.
---
# Compared with GDPR
GDPR: **protecting citizens against the misuse of personal data**. Caused an obsession with data confidentiality and Cookie Banners.
NIS 2: **resilience of critical infrastructure**, threat of disruption. Emphasis on risk management.
---
# Origins of NIS 2
The original Network and Information Security Directive (NIS1) was adopted in 2016. It was the **EUs first comprehensive cybersecurity law**.
Aimed to establish a high common level of cybersecurity across Member States.
Targeted critical sectors: energy, transport, healthcare, finance, water, and digital infrastructure.
Required essential service providers (OES) and digital service providers to take security measures and report incidents.
---
# But ...
**Scope was too narrow:** Only applied to seven key sectors identified by Member States.
**Inconsistent Implementation:** Member States had discretion in identifying OES.
**Unclear Definitions:** Contributed to fragmentation and gaps in protection. Some critical digital infrastructure and services were not covered.
Digital Service Providers were subject to lighter requirements, whereas **digitalization accelerated** and **cyber threats became more sophisticated**.
---
# So: NIS 2
NIS2 expands the scope, introduces stricter supervision/enforcement, harmonizes sanctions, and emphasizes supply chain security and top management responsibility.
Proposal for NIS2 in December 2020.
Formal adoption: November 2022.
**Entered into force: January 16, 2023**.
Member States required to transpose NIS2 into national law by **October 17, 2024**.
Current state: European Commission has **warned 19 Member States for missing the deadline** and may take legal action.

---
# Role of Management
Cybersecurity is a core element of corporate governance**.
Management bodies must approve cybersecurity risk-management measures and oversee implementation.
**Can be held liable for infringements**.
Management is **required to follow training** to gain sufficient knowledge and skills.
Entities are encouraged to offer similar training to employees.
---
---
**Slide 27: Supervision and Enforcement**
* Member States must ensure competent authorities effectively supervise and take necessary measures for compliance.
* Supervisory tasks can be prioritized based on a risk-based approach.
* Essential entities are subject to comprehensive ex ante and ex post supervision.
* Important entities are subject to lighter, ex post only supervision, typically triggered by evidence of non-compliance.
* Essential entities are subject to a **comprehensive ex ante and ex post supervisory regime**.
* authorities have a general obligation to supervise these entities. Supervisory tasks can include regular on-site inspections, off-site supervision, random checks, regular and targeted security audits, and security scans
*
* Important entities are subject to a **light, ex post only, supervisory regime**, typically triggered by evidence of non-compliance.
* supervision is specifically triggered by "evidence, indication or information" suggesting they may not comply with the directive
---
**Slide 28: Enforcement Powers**
* Competent authorities for **Essential Entities** have powers including:
* Issuing warnings.
* Adopting binding instructions (e.g., measures to prevent/remedy incidents, time-limits).
* Ordering entities to remedy deficiencies or infringements.
* Competent authorities for **Important Entities** have powers including:
* Issuing warnings.
* Adopting binding instructions or orders to remedy deficiencies/infringements.
---
**Slide 29: Penalties for Non-Compliance**
* **Fines:** Up to €10 million or 2% of global annual revenue, whichever is higher.
* **Management Liability:** Executives face personal liability for non-compliance. This could include potential bans from managerial roles.
* **Market Access Risks:** Non-compliance may disrupt partnerships with EU businesses or lead to exclusion from EU markets.
* Member States may lay down rules on imposing administrative fines on public administration entities.
---
**Slide 30: Expectations for Enforcement (as of May 2025)**
* Enforcement across the EU is currently marked by significant delays and fragmentation.
* Many Member States missed the October 2024 transposition deadline.
* Formal warnings issued by the European Commission to 19 Member States.
* Legal action by the Commission may follow if compliance is not achieved.
* Actual enforcement will depend on national transposition and the approach taken by each Member State's competent authorities.
---
---
---
---
**Slide 22: Incident Reporting (Significant Incidents)**
* NIS2 lays down a **multiple-stage approach** to reporting significant incidents.
* Strikes a balance between swift reporting (mitigate spread, seek assistance) and in-depth reporting (lessons learned).
* Report incidents that, based on initial assessment, could cause severe operational disruption/financial loss or affect others with considerable material/non-material damage.
* Initial assessment considers affected systems, threat severity/characteristics, vulnerabilities, and entity experience.
* Member States must provide technical means for simplified reporting (single entry points, online forms, etc.).
* This should ideally be a single entry point for various notification obligations (like GDPR, ePrivacy) to decrease administrative burden.
---
**Slide 23: Voluntary Information Sharing**
* Member States must ensure entities (in-scope and others) can **voluntarily exchange relevant cybersecurity information**.
* Information includes cyber threats, near misses, vulnerabilities, techniques, indicators of compromise, threat actors, alerts, and configuration recommendations.
* Exchange should occur within communities of entities and their suppliers/providers.
* Information-sharing arrangements should respect the sensitive nature of the information.
* Member States should facilitate the establishment of such arrangements.
* Entities must notify competent authorities of participation/withdrawal from these arrangements.
* ENISA provides assistance by exchanging best practices and guidance.
---
**Slide 24: Voluntary Notifications**
* In addition to mandatory reporting, entities can **voluntarily notify** CSIRTs or competent authorities.
* This applies to essential/important entities (incidents, cyber threats, near misses) and other entities (significant incidents, cyber threats, near misses).
* Voluntary reporting is processed but may be prioritized below mandatory notifications.
* Voluntary reporting should **not result in additional obligations** for the notifying entity.
---
**Slide 25: NIS2 Certification Status**
* The European Commission is working on a certification framework, but it is **still under development and not currently in force**.
* The NIS2 Directive itself does not mandate certification for companies, but allows for future requirements.
* Any companies currently offering "NIS-2 certification" or training do so based on their own interpretations or existing standards (like ISO 27001).
* These commercial offerings **do not have official legal status** and are **not legally recognized** EU-level certifications.
---
**Slide 26: NIS2 Measures and International Standards**
* Member States are encouraged to use **European and international standards** and technical specifications relevant to network and information system security.
* Measures for NIS2 conformity in places like Flemish Belgium are based on internationally recognized standards like **NIST processes and ISO 27001/27002**.
* ISO 27001/27002 and the NIST framework are recognized as best practices for NIS2 compliance.
* Specific NIS2 requirements, such as those related to risk management and physical/environmental security, align with standards like the ISO/IEC 27000 series.
* International standards ISO/IEC 30111 and ISO/IEC 29147 provide guidance on vulnerability handling and disclosure.
* ENISA, in cooperation with Member States, provides advice/guidelines on relevant standards.
**Slide 31: Cooperation Mechanisms**
* **Cooperation Group:** Supports strategic cooperation and information exchange among Member States. Tasks based on biennial work programmes. Can conduct coordinated security risk assessments of critical supply chains. Discusses peer review reports.
* **CSIRTs Network:** Promotes swift and effective operational cooperation among national CSIRTs. Tasks include incident handling assistance, coordinating vulnerability disclosure, and identifying further forms of operational cooperation. Cooperates with regional/Union-level SOCs.
* **EU-CyCLONe:** Supports coordinated management of large-scale cybersecurity incidents and crises at operational level. Composed of representatives from Member States' cyber crisis management authorities and the Commission (in specific cases).
---
**Slide 32: Vulnerability Handling**
* Identifying and remedying vulnerabilities is crucial.
* Entities that develop or administer systems should establish procedures to handle vulnerabilities.
* Manufacturers/providers should have procedures to receive vulnerability information from third parties.
* **Coordinated vulnerability disclosure** (CVD) is a structured process for reporting vulnerabilities to allow remediation before public disclosure. International standards ISO/IEC 30111 and ISO/IEC 29147 provide guidance.
* Each Member State must designate a CSIRT as a coordinator for CVD.
* This coordinator acts as a trusted intermediary between the reporter and the manufacturer/provider.
* Reporters can report vulnerabilities anonymously.
* **European vulnerability database:** ENISA will develop and maintain a database for voluntary disclosure of publicly known vulnerabilities in ICT products/services. Provides information on the vulnerability, affected products/services, severity, and available patches/mitigation guidance.
---
**Slide 33: DNS Security and Registration Data**
* Maintaining accurate/complete domain name registration data (WHOIS) is essential for DNS security/stability.
* TLD name registries and domain name registration service entities must collect and maintain this data diligently, in accordance with data protection law for personal data.
* Data must include information to identify and contact holders and administrative points of contact (name, email, phone).
* Policies/procedures, including verification, must be in place to ensure accuracy.
* Publicly available data should include non-personal data, such as the registrant name and phone number for legal persons. A non-personal email can also be published.
* Lawful access to personal data must be enabled for legitimate access seekers in line with data protection law. Access requests should be responded to without undue delay.
* All types of access to registration data should be free of charge.
* ENISA will create and maintain a registry of specific cross-border providers, including TLD name registries and domain name registration services, based on Member State information.
---
**Slide 34: Need for Ongoing Review**
* The European Commission will periodically review NIS2, consulting stakeholders.
* Reviews, starting by October 17, 2027, will assess the relevance of entity size, sectors, and types in relation to cybersecurity.
* Will take into account reports from the Cooperation Group and CSIRTs network.
* Legislative proposals may accompany reports where necessary.
---
**Slide 35: Key Takeaways**
* NIS2 is a significant evolution from NIS1, addressing its shortcomings by expanding scope and harmonizing requirements.
* Targets a broad range of critical entities, imposing comprehensive cybersecurity risk management and reporting obligations.
* Places clear accountability on top management.
* Emphasizes supply chain security and third-party risk management.
* Implementation is facing delays in many Member States as of May 2025.
* International standards like ISO 27001 and NIST are relevant for compliance, though no official EU certification exists yet.
* Enforcement includes significant fines and potential management liability.
