The European Union (EU) is actively working to harmonize cybersecurity regulations across its single market, seeking to create a more robust and unified digital ecosystem. With rising cybersecurity risks, the harmonization of standards is key to fostering trust, safeguarding citizens, and promoting economic growth. 

Comprising 27 Member States, the EU is a patchwork of policies, and when it comes to cybersecurity, national cybersecurity laws can vary widely, leading to significant discrepancies and gaps in security measures. Due to the interconnected nature of cyber threats, risks cannot be effectively mitigated when states operate under divergent laws and regulations. An attack in one country can send shockwaves across the EU – cyberattacks do not recognize borders. When one is impacted, all are impacted. Thus, EU cybersecurity regulations within the EU single market are essential for creating a resilient approach to combating cybercrime, protecting critical infrastructure, and ensuring the safety of digital services. 

To discuss the challenges rising from differences in how Member States implement and transpose EU regulations and directives as well as the complexities of fostering cross-border cooperation in cybersecurity, join the Cybersecurity Coalition and Cyber Threat Alliance in Brussels for the second annual CyberNext BRU conference on 5 March at the Stanhope Hotel. The event offers a range of sessions addressing today’s most pressing cybersecurity challenges, including a panel entitled Harmonising Cybersecurity Regulations in the EU Single Market, which will focus on the continuous efforts to clarify, align, and harmonize the EU’s cybersecurity regulatory framework. The panel will examine several key developments currently unfolding in the EU, including: 

Cybersecurity Act (CSA) 

The CSA, which came into effect in 2019, established a permanent mandate for the European Union Agency for Cybersecurity (ENISA) and introduced an EU-wide cybersecurity certification framework. ENISA is responsible for establishing and maintaining the cybersecurity certification framework, including preparing the technical groundwork for specific certification schemes and providing public information through a dedicated website. Additionally, the agency is tasked with enhancing operational cooperation at the EU level, assisting Member States with cybersecurity incidents, and coordinating responses to large-scale cross-border cyberattacks and crises.

The CSA establishes a unified cybersecurity certification framework for information and communication technology (ICT) products, services, and processes across the EU, streamlining and strengthening the security standards. With this framework, companies operating in the EU only need to certify their ICT offerings once, with the certification being recognized throughout the entire EU, enabling:

• A single market for cybersecurity certification of ICT products, services, and processes, creating consistency across borders.
• Enhanced trust and security.
• Cross-border cooperation, promoting mutual recognition of cybersecurity certifications and standards. 

NIS2 Directive‍

The NIS2 Directive, which became applicable on October 18, 2024, expands upon its predecessor, the NIS1 Directive, to strengthen cybersecurity across the EU. Key aspects of the directive include: 

• Expanding the scope to cover 18 critical sectors, including digital infrastructure, energy, transport, and healthcare.
• Introducing stricter supervision tools and enforcement measures.
• Implementing risk management measures and reporting requirements across a broader range of sectors.
• Establishing a network of Computer Security Incident Response Teams (CSIRTs) for coordinated incident response.

The NIS2 Directive establishes new requirements and responsibilities for organizations across four key areas: risk management, corporate accountability, reporting duties, and business continuity. This directive modernizes the EU’s cybersecurity framework to address increasing risks within the evolving digital landscape, enhancing the resilience of critical infrastructure and ensuring that relevant sectors are equipped with tools to mitigate cyber risks. This harmonized approach not only strengthens the security of vital services but also addresses vulnerabilities in supply chains, enforces accountability for non-compliance, and fosters a unified level of cybersecurity across the EU internal market.

Cyber Resilience Act (CRA)

The CRA, which entered into force on December 10, 2024, and will fully apply from December 11, 2027, aims to strengthen cybersecurity standards for products with digital components, mandating that manufacturers and retailers maintain cybersecurity measures throughout the entire lifecycle of their products. Among other items, the act: 

• Introduces mandatory cybersecurity requirements for manufacturers of hardware and software products.
• Requires manufacturers to provide security and care throughout a product's lifecycle.
• Implements the obligation of the CE marking to indicate compliance with the CRA’s requirements.

The CRA aims to address cybersecurity threats by establishing cybersecurity requirements for digital products, enhancing harmonization in the EU’s cybersecurity landscape and fostering a more integrated digital ecosystem. By promoting coordinated incident response among Member States and simplifying compliance processes for businesses, the EU single market can become both more secure from cyber risks and economically efficient.
