NIS2 and GDPR: How the Two Regulations Work Together

In Ireland, a recent survey revealed that over 60% of SMEs experienced a cyberattack in the past year, highlighting the pervasive threat landscape. For many Irish businesses, navigating the complexities of cybersecurity and data privacy regulations can feel like a daunting task. With the impending implementation of the NIS2 Directive and the established General Data Protection Regulation (GDPR), understanding the NIS2 GDPR overlap is no longer optional—it's essential for safeguarding your operations and avoiding significant penalties. Both regulations aim to enhance digital resilience, but they approach the challenge from different angles, creating a synergistic relationship that, when understood correctly, can strengthen your overall data protection cybersecurity posture.

Understanding GDPR: The Foundation of Data Protection

GDPR, enacted in 2018, fundamentally reshaped how organisations handle personal data. For Irish SMEs, its core principles are paramount: lawfulness, fairness, transparency, purpose limitation, data minimisation, accuracy, storage limitation, integrity, confidentiality, and accountability. The Data Protection Commission (DPC) in Ireland is the supervisory authority, actively enforcing these principles. GDPR mandates robust technical and organisational measures to protect personal data, including encryption, pseudonymisation, and regular security assessments. A key aspect for businesses is the requirement to report data breaches within 72 hours to the DPC, especially if there's a risk to individuals' rights and freedoms. Non-compliance can lead to hefty fines, up to €20 million or 4% of global annual turnover, whichever is higher. Therefore, a strong data protection cybersecurity framework is not just good practice; it's a legal imperative under GDPR.

Introducing NIS2: Enhancing Network and Information System Security

Building upon the original NIS Directive, NIS2 broadens its scope significantly, bringing many more Irish SMEs into its regulatory net. While GDPR focuses on personal data, NIS2 targets the security of network and information systems that are critical for the provision of essential or important services. This includes sectors like energy, transport, banking, health, digital infrastructure, and even certain digital providers. The National Cyber Security Centre (NCSC) Ireland is expected to play a central role in its implementation and oversight. NIS2 mandates a comprehensive set of cybersecurity risk management measures, including incident handling, supply chain security, network and information system security, and the use of cryptography and multi-factor authentication. Crucially, NIS2 also introduces stricter incident reporting requirements, often with shorter timelines than GDPR, and imposes significant penalties for non-compliance, aligning with the EU's commitment to bolster cyber resilience across the Union. The directive aims to create a higher common level of cybersecurity across member states, directly impacting how Irish businesses manage their digital risks.

The NIS2 GDPR Overlap: A Unified Approach to Security

The NIS2 GDPR overlap is significant and intentional. Both regulations share the common goal of protecting digital assets and ensuring trust in the digital economy. Where GDPR protects the data itself, NIS2 protects the systems and networks that process, store, and transmit that data. Consider a cyberattack that compromises customer data. Under GDPR, this is a personal data breach requiring notification to the DPC and affected individuals. Under NIS2, if this attack impacts the continuity of an essential service or leads to significant operational disruption, it would also trigger NIS2 incident reporting obligations to the NCSC. Therefore, effective data protection cybersecurity measures, such as access controls, encryption, incident response plans, and regular security audits, serve a dual purpose, helping businesses comply with both regulations simultaneously. The NCSC Ireland and the DPC are likely to collaborate closely on enforcement, making a unified approach to compliance more critical than ever for Irish SMEs.

Practical Steps for Irish SMEs to Satisfy Both Regulations

Cybersecurity is no longer optional for Irish businesses. navigating the combined requirements of NIS2 and GDPR can be streamlined by focusing on common areas. Here are practical steps:

• Comprehensive Risk Assessments: Conduct regular, thorough risk assessments that consider both data protection and cybersecurity risks. Identify vulnerabilities in your systems and processes that could lead to data breaches or service disruptions.
• Robust incident response plan: Develop and regularly test an incident response plan that addresses both data breaches (GDPR) and cybersecurity incidents (NIS2). This plan should clearly define roles, responsibilities, communication protocols (internal and external, including to the DPC and NCSC), and recovery procedures.
• supply chain security: Both regulations emphasise the importance of securing your supply chain. Vet your third-party vendors and ensure they have adequate data protection and cybersecurity measures in place, especially if they handle your data or provide critical services.
• Technical and Organisational Measures: Implement strong technical controls like multi-factor authentication (MFA), encryption, regular patching, and secure configurations. Complement these with organisational measures such as employee training on data protection and cybersecurity best practices.
• Documentation and Accountability: Maintain detailed records of your compliance efforts, including policies, procedures, risk assessments, and incident logs. This demonstrates accountability, a core principle of GDPR, and provides evidence of due diligence under NIS2.

By integrating your compliance efforts, you can avoid duplication and build a more resilient and secure business environment.

What This Means for Your Business

The convergence of NIS2 and GDPR means that cybersecurity is no longer just an IT issue; it's a fundamental business risk that requires board-level attention. For Irish SMEs, this translates into a need for proactive engagement with both data protection and network security. Ignoring either regulation can lead to severe financial penalties, reputational damage, and operational disruption. More importantly, a robust data protection cybersecurity strategy, informed by the NIS2 GDPR overlap, builds trust with your customers and partners, fostering a secure environment for growth. The Irish regulatory landscape, with the DPC and NCSC, is evolving to ensure a higher standard of digital resilience. Businesses that embrace this integrated approach will be better positioned to thrive in an increasingly complex digital world.
