Summary for the C-level management

NIS2.0 is the new EU directive on network and information security that aims to improve the resilience and preparedness of critical sectors and essential services against cyber threats. It will enter into force in October 2024 and will apply to organizations with more than 250 people. NIS2 applies to an organisation either:

a) directly if your organization operates in a field defined in the directive, or

b) if your client is an organization that operates in a field where NIS2 applies. Supply chain security, including security aspects of the relationship between each operator and its direct suppliers or service providers, is included in the directive.

NIS2-directive will require organizations to comply with a set of standards and obligations, such as reporting incidents, conducting risk assessments, implementing security measures, and cooperating with national authorities.

If you work in C-level management, you need to be aware of the implications of NIS2.0 for your organization and your customers. You need to ensure that your IT systems, processes, and staff are aligned with the new requirements and that you have a clear strategy and action plan to achieve compliance. You also need to communicate with your customers about the benefits of NIS2.0 and how it will enhance their security and trust in your services.

NIS2 will have a significant impact on business operations, reputation, and competitiveness. NIS2 will require companies to invest more in cybersecurity, comply with new rules and standards, and cooperate with national authorities and other stakeholders.

Failure to do so could result in fines of up to 10% of annual turnover, as well as reputational damage and loss of customer trust. On the other hand, complying with NIS2 can also bring benefits, such as improved resilience, innovation, and market opportunities.

NIS2 is not only a challenge, but also an opportunity for C-level management to demonstrate their leadership and commitment to cybersecurity.

More in detail: What NIS2.0 is and what are the key changes?

Let’s get to know the topic deeper. NIS2 is the new European cybersecurity directive that will replace the existing NIS1 Directive in October 2024. NIS2 expands the scope of the previous NIS1 Directive.

NIS2 is the most comprehensive EU cybersecurity legislation to date, covering 15 sectors including new sectors such as manufacturing and research. It includes medium-sized companies that are identified as critical infrastructure.


Essential sectors:Important sectors:
EnergyPostal and courier services
TransportWaste management
Financial market infrastructureFood
Health sectorManufacturing of medical devices
Drinking waterDigital providers

Directives purpose is to establish a baseline of minimum-security measures for digital service providers and operators of essential services, to mitigate the risk of cyber attacks and to improve the overall level of cybersecurity in the EU.

Key Changes from NIS1 Directive to NIS2

• NIS2 sets out a benchmark of minimum measures:
That companies need to take actions to improve their cybersecurity posture. These include conducting risk assessments, implementing multi-factor authentication, and having plans for incident response and supply chain security.

• NIS2 introduces stricter enforcement:
Through enhanced measures and sanctions for non-compliance with the directive, as well as more stringent supervisory measures for national authorities.

• NIS2 establishes a framework for coordinated vulnerability disclosure
and creates an EU registry for vulnerabilities, operated by ENISA, The European Union Agency for Cybersecurity.

• NIS2 also enhances cooperation and information sharing between Member States and their authorities, including on cyber crisis management.

To comply with NIS2, you will need to take the following steps:

  1. Identify your role and obligations under the NIS2 Directive. Depending your role, you will have different responsibilities and requirements to meet.

2. Assess your current level of cybersecurity and identify any gaps or weaknesses. You will need to follow common standards and guidelines for security and resilience that will be developed by ENISA and the European Commission.

3. Implement appropriate security measures and policies to protect your systems and data from cyber threats. You will need to adopt a risk-based approach and ensure that your security measures are proportionate to the level of risk you face.

4. Report any significant or major incidents to your national authorities and ENISA. You will need to follow a harmonized framework for incident notification that will specify the thresholds, formats and procedures for reporting.

5. Cooperate with your national authorities and other stakeholders. You will need to participate in regular audits and inspections by your national authorities and share information and best practices with other actors in your sector or across sectors.

Cybersecurity Risk Management Measures

NIS 2 employs a risk-based, outcome-focused approach to measures addressing:

  1. risk analysis & information system security policies;
  2. incident handling;
  3. business continuity and crisis management;
  4. supply chain security;
  5. security in network and information system acquisition, development, and maintenance, including vulnerability handling and disclosure;
  6. policies and procedures to assess the efficacy of cybersecurity risk management measures;
  7. basic cybersecurity hygiene and training;
  8. policies and procedures regarding cryptography and encryption;
  9. HR security, including access control policies and asset management; and
  10. the use of MFA or continuous authentication solutions (Zero Trust) and other technical controls.

Incident Reporting

Report “incidents having a significant impact on the provision of their services” = causing severe operational disruption of the service or financial losses ; affecting other persons by causing considerable material or non-material losses.

  1. within 24 hours submit to the relevant authority an “early warning”
  2. without delay submit mitigation and prevention information.
  3. within 72 hours submit an “incident notification” (assessment, severity, indicators of compromise)
  4. upon request from the regulating agency submit interim reports
  5. within one month of initial awareness it will be required to submit either a final report or a progress report followed by further monthly progress reports until a final report.
