Leveraging NIS2 as a strategic opportunity for OT operators

No matter how you look at it, far from being merely a regulatory burden, NIS2 presents a strategic opportunity for organizations to enhance their resilience, build trust, and gain a competitive edge. Our latest blog post will delve into the profound impact of NIS2, highlight the opportunities it presents, and lastly provide a detailed roadmap for achieving compliance.

Why NIS2 matters now more than ever

The rationale behind NIS2 is clear: the increasing interconnectedness of digital systems means that a cyberattack on one entity can have a cascading effect across an entire sector, or even across national borders. NIS2 aims to address this by:

· Broadening the Scope: NIS1 primarily focused on "Operators of Essential Services" (OES) in a limited number of critical sectors. NIS2 significantly expands this, now encompassing a much wider range of "Essential" and "Important" entities across 18 sectors. This includes, but is not limited to, energy, transport, health, banking, financial market infrastructures, digital infrastructure, public administration, manufacturing, food production, waste management, postal and courier services, and certain digital service providers like cloud computing services, online marketplaces, and search engines. Estimates suggest over 100,000 additional organizations will now fall under NIS2's purview.

· Strengthening Security Requirements: NIS2 mandates more rigorous cybersecurity risk management measures. Organizations are required to implement a comprehensive set of technical, operational, and organizational measures to manage risks to their network and information systems. These measures include, but are not limited to:

· Risk analysis and information system security policies.

· Incident handling (prevention, detection, and response).

· Business continuity and crisis management.

· Supply chain security.

· Security in network and information systems acquisition, development, and maintenance.

· Policies and procedures regarding the use of cryptography and encryption.

· Human resources security, access control policies, and asset management.

· Basic cyber hygiene practices and cybersecurity training.

· Use of multi-factor authentication (MFA) or continuous authentication solutions.

· Assessment of the effectiveness of cybersecurity risk management measures.

· Enhancing Incident Reporting: The directive introduces stricter and more streamlined incident reporting obligations. Entities must notify relevant national authorities (CSIRTs or competent authorities) of significant incidents without undue delay. This includes an "early warning" within 24 hours of becoming aware of the incident, followed by a more detailed incident notification within 72 hours.

· Increasing Corporate Accountability: A significant shift in NIS2 is the emphasis on corporate accountability. Management bodies are now directly responsible and can be held liable for infringements. They are required to approve cybersecurity risk-management measures, oversee their implementation, and participate in cybersecurity training. In cases of gross negligence and repeated violations, temporary bans from managerial functions are also possible.

· Stricter Enforcement and Penalties: Non-compliance under NIS2 carries substantial penalties. For Essential entities, fines can reach up to €10 million or 2% of the total annual worldwide turnover, whichever is higher. For Important entities, the maximum fine is €7 million or 1.4% of the total annual worldwide turnover. Beyond monetary fines, national supervisory authorities can impose non-monetary remedies, such as compliance orders, binding instructions, security audit implementation orders, and even orders to notify customers of threats.

NIS2: An Opportunity, Not Just a Compliance Burden

While the regulatory pressure of NIS2 is undeniable, forward-thinking organizations recognize it as a pivotal opportunity to drive tangible business benefits. Compliance should not be viewed as a checkbox exercise, but rather as a strategic investment in long-term resilience and competitive advantage.

Despite the advantages, many businesses are struggling to comply with NIS2 as per ENISA. Many sectors are unable to comply with the directives even today. 

Here's how NIS2 can unlock new opportunities:

· Improved efficiency and visibility into networks and operations: With improvement in security levels, the ability of businesses to take decisions on security and beyond will also rise. Every measure that improves decision making will ultimately aid in improved institutional efficiency in some way.

· Enhanced cyber resilience and business continuity: At its core, NIS2 forces organizations to mature their cybersecurity posture. By implementing robust risk management, incident response, and business continuity plans, entities become inherently more resilient to cyber threats. This translates directly into reduced downtime, minimized financial losses from breaches, and greater operational stability.

· Increased trust and reputation: In an era of rampant cyberattacks, consumers and partners are increasingly concerned about the security practices of the organizations they interact with. NIS2 compliance signals a strong commitment to cybersecurity and data protection, bolstering trust among customers, stakeholders, and the broader market. This enhanced reputation can be a significant differentiator in competitive landscapes.

· Competitive advantage in the supply chain: NIS2 places a strong emphasis on supply chain security. Organizations are required to assess and address the cybersecurity risks posed by their direct suppliers and service providers. For businesses that can demonstrate their own robust NIS2 compliance, this can be a significant competitive advantage when seeking to partner with or supply to other in-scope entities. Being a "trusted" link in the digital supply chain becomes a powerful selling point.

· Innovation and digital transformation: A secure and resilient digital foundation, as mandated by NIS2, provides a stable platform for innovation. With robust security measures in place, organizations can more confidently explore and implement new technologies, digital solutions, and business models, knowing that their core systems are protected. This can accelerate time-to-market for new offerings and drive greater efficiency.

· Improved internal governance and culture: The directive's focus on corporate accountability elevates cybersecurity to a board-level concern. This fosters a more security-conscious culture throughout the organization, from top management down to every employee. Regular training and awareness programs, as required by NIS2, empower employees to become a proactive defense line against cyber threats.

· Potential for reduced insurance premiums: As organizations demonstrate a higher level of cybersecurity maturity through NIS2 compliance, they may be able to negotiate more favorable terms on cyber insurance policies. Insurers are increasingly looking for robust risk management practices, and NIS2 provides a clear framework for demonstrating these.

The NIS2 Compliance Roadmap

Achieving NIS2 compliance requires a structured, systematic approach. This roadmap outlines the key phases and steps organizations should undertake:

Phase 1: Assessment and Scoping (Immediate Priority)

· Determine if NIS2 applies to your business: This is the foundational step. Carefully review Annexes I ("High Criticality Sectors" - Essential Entities) and II ("Other Critical Sectors" - Important Entities) of the NIS2 Directive. Consider your size (at least 50 employees or €10 million turnover generally, with exceptions for certain critical entities regardless of size) and the nature of your services. Don't assume you're exempt; the expanded scope catches many previously unaffected entities, including MSPs and managed security service providers (MSSPs).

· Identify Essential/Important Services and Associated Assets: Once in scope, identify the specific services you provide that fall under NIS2 and the critical network and information systems (ICT products, networks, infrastructure, applications, data) that support them. This forms the basis for your risk assessment.

· Conduct a comprehensive NIS2 risk assessment and gap analysis: This is a crucial diagnostic step. Compare your current cybersecurity posture, policies, procedures, and technical controls against the detailed requirements of NIS2 (Article 21 risk management measures, incident reporting obligations, governance requirements). This will identify specific areas of non-compliance and pinpoint the "gaps" you need to address. This analysis should extend to your supply chain.

· Define and secure management buy-in: Given the increased corporate accountability, securing strong buy-in from the management body (board of directors, senior leadership) is paramount. Educate them on NIS2's implications, their personal liabilities, and the strategic opportunities. This will ensure resources and commitment are allocated for compliance.

· Incident response: Focus on refining your incident response strategy and approach.

Phase 2: Strategy Development and Planning (Short-to-Medium Term)

· Develop a Cybersecurity Risk Management Strategy: Based on your gap analysis, formulate a robust, documented cybersecurity risk management strategy. This strategy should outline how your organization identifies, assesses, and mitigates risks to its network and information systems. It must be an "all-hazards" approach, considering a wide range of threats. IEC 62443-2-1 can be considered as a guide for formulating this strategy

· Establish/Consolidate Incident Management and Reporting Processes: NIS2's stringent reporting timelines (24-hour early warning, 72-hour detailed notification) necessitate a highly efficient incident response plan. Review and enhance your existing incident detection, analysis, containment, eradication, recovery, and post-incident review procedures. Ensure clear communication channels with relevant authorities (CSIRTs).

· Address Supply Chain Security: This is a key focus of NIS2. Implement policies and procedures to assess the cybersecurity posture of your direct suppliers and service providers. This may involve contractual clauses, security questionnaires, and regular audits to ensure their alignment with NIS2 requirements, as their vulnerabilities can become yours.

· Formulate Business Continuity and Crisis Management Plans: Develop and regularly test comprehensive business continuity and disaster recovery plans to ensure the uninterrupted delivery of essential services in the event of a cyber incident or other disruption. This includes robust backup and recovery mechanisms.

· Strengthen Governance and Accountability Frameworks: Formalize the roles and responsibilities of the management body regarding cybersecurity oversight. Implement regular cybersecurity training for management and employees. Review internal policies to align with NIS2's corporate accountability provisions.

Phase 3: Implementation and Operationalization (Medium-to-Long Term)

· Implement Technical and Organizational Security Measures: This is where the rubber meets the road. Based on your risk assessments and strategy, deploy and configure the necessary security controls. This includes, but is not limited to:

· Identity and Access Management (IAM): Implement strong access controls, multi-factor authentication (MFA) for all critical systems, and zero-trust principles.

· Data Security: Deploy encryption for data at rest and in transit, implement data loss prevention (DLP) solutions, and establish data classification frameworks.

· Network and System Hardening: Apply patches and updates promptly, implement secure configurations (e.g., CIS Benchmarks), and segment networks.

· Continuous Security Monitoring: Implement tools and processes for continuous monitoring of network traffic, endpoints, and cloud environments to detect suspicious activities and intrusions. Consider Managed Extended Detection and Response (MXDR) services for 24/7 monitoring.

· Cyber Hygiene and Training: Conduct regular and tailored cybersecurity awareness training for all employees, covering topics like phishing, social engineering, and secure remote work practices.

· Cryptography and Encryption: Ensure the appropriate use of cryptographic solutions to protect data confidentiality and integrity.

· Asset Management: Maintain a comprehensive and up-to-date inventory of all critical information assets.

· Document Everything: Maintain thorough documentation of all cybersecurity policies, procedures, risk assessments, incident response plans, and implemented security measures. This documentation will be crucial for demonstrating compliance during audits.

· Integrate Security into SDLC/Procurement: Embed security by design and by default into your systems acquisition, development, and maintenance processes. Ensure security is a key consideration from the initial design phase through to deployment and ongoing operations.

Phase 4: Monitoring, Review, and Continuous Improvement (Ongoing)

· Continuous Monitoring and Auditing: NIS2 emphasizes ongoing vigilance. Implement continuous monitoring of your security controls and conduct regular internal and external audits, penetration testing, and vulnerability assessments to identify weaknesses and ensure the effectiveness of your security measures.

· Regularly Review and Update Policies and Procedures: The threat landscape is dynamic, so your cybersecurity posture must also evolve. Periodically review and update your risk assessments, security policies, and incident response plans to reflect new threats, technologies, and organizational changes.

· Engage with Competent Authorities: Establish a designated contact point within your organization for communication with the relevant national authorities (CSIRTs, competent NIS2 authorities). Proactively engage with them for guidance and stay informed about national implementation specifics.

· Leverage External Expertise: For many organizations, the complexity of NIS2 compliance will necessitate engaging external cybersecurity consultants, legal experts, or managed security service providers. Their expertise can be invaluable in navigating the requirements, conducting gap analyses, and implementing appropriate solutions.

· Increase awareness levels

· Improve incident response capabilities: To respond to any event with the level of attention that is required

The NIS2 Directive is a strategic inflection point for cybersecurity in the European Union and beyond. By understanding its comprehensive requirements, recognizing the opportunities it presents, and diligently following a structured compliance roadmap, organizations can transform a compliance obligation into a powerful catalyst for enhanced resilience, increased trust, and sustainable growth in the years to come.
