Cybersecurity has become a core pillar of economic security. Cyberattacks targeting financial systems, energy grids, telecommunications networks, and digital infrastructure can cause severe short-term disruption and long-term structural damage to the European Union’s economy. Beyond direct attacks, systemic vulnerabilities also arise from dependencies on vendors originating from high-risk or unreliable jurisdictions. Such dependencies may expose critical infrastructure to shutdowns, service throttling, data manipulation, or the weaponisation of supply chains.

In response to this evolving threat landscape, the European Commission has proposed a revision of the Cybersecurity Act. The reform aims to strengthen the mandate of the European Union Agency for Cybersecurity (ENISA), enhance EU-wide crisis coordination, and streamline the cybersecurity certification framework to better safeguard the Single Market. The initiative reflects a broader strategic shift: cybersecurity is no longer viewed solely as a technical domain, but as a central component of Europe’s economic resilience and strategic autonomy.

This paper evaluates whether the current EU cybersecurity architecture is sufficient to address emerging risks and assesses the extent to which the proposed revision strengthens Europe’s digital and economic security.

Methodology

This research applies a qualitative policy analysis approach, including:

1. Comparative legal analysis of the current Cybersecurity Act and the proposed revisions.
2. Policy review of related EU frameworks concerning economic security, critical technologies, and supply chain resilience.
3. Case analysis of prior coordination mechanisms, particularly the 5G Toolbox framework.
4. Strategic assessment of institutional capacity, implementation feasibility, and governance implications.

The analysis draws on official EU communications, regulatory texts, and public policy discussions to assess both normative intent and practical implications.

Context: From Technical Protection to Economic Security

The EU’s cybersecurity framework was initially designed to harmonize standards, improve cooperation, and establish a voluntary certification scheme. However, geopolitical tensions and state-linked cyber operations have transformed the threat landscape.

The experience of the EU 5G Toolbox demonstrated the limits of voluntary coordination. While Member States agreed on common risk-mitigation measures, implementation varied significantly across the Union. This divergence exposed regulatory fragmentation within the Single Market and revealed that soft coordination mechanisms may be insufficient when national security and economic interests diverge.

The revision of the Cybersecurity Act therefore reflects a shift toward a more centralized and operational approach to European cyber resilience.

Key Findings

1. Voluntary Mechanisms Have Structural Limitations

The 5G experience highlights that non-binding guidance does not ensure uniform risk mitigation. Divergent national approaches create uneven levels of protection and systemic vulnerabilities within interconnected EU infrastructure.

2. Strengthening ENISA Is Strategically Necessary

Expanding ENISA’s mandate and operational capacity enhances the EU’s ability to coordinate responses to cross-border cyber crises. A stronger agency can facilitate information sharing, joint preparedness, and rapid incident response.

3. Cybersecurity Is Increasingly Linked to Economic Sovereignty

The reform explicitly aligns cybersecurity with the protection of critical technologies, supply chains, and digital infrastructure. This marks a conceptual shift toward integrating cyber policy into the EU’s broader economic security strategy.

4. Certification Reform Can Protect the Single Market

Streamlining and reinforcing the EU cybersecurity certification regime may reduce fragmentation, increase trust in digital products and services, and protect the integrity of the Single Market.

5. Implementation Remains the Core Challenge

Even with strengthened legal tools, enforcement depends on Member State cooperation and resource allocation. Institutional capacity gaps and political divergences could limit the effectiveness of the reform.

Policy Implications

The revision signals a move toward greater centralization and strategic coordination in EU cyber governance. However, its success depends on:

• Political consensus among Member States.
• Clear enforcement mechanisms regarding high-risk vendors.
• Adequate funding and staffing for ENISA.
• Integration with broader EU economic security initiatives.

Without coherent implementation, regulatory ambition may not translate into practical resilience.

Conclusion

The proposed revision of the EU Cybersecurity Act represents an important step in adapting Europe’s regulatory framework to a rapidly evolving threat environment. It acknowledges that cybersecurity is inseparable from economic security and strategic autonomy.

However, legal reform alone cannot guarantee resilience. Effective coordination, political alignment, and sustained institutional strengthening will determine whether the EU can future-proof its digital infrastructure and protect its economic foundations in an era of intensifying cyber competition.
