The European Union (EU) has taken significant steps addressing the evolving challenges posed by cyber threats, particularly in relation to its critical infrastructure. As the landscape of cyber risks continues to shift, with nation-state cyber attacks becoming increasingly frequent and sophisticated, the EU has recognized the urgent need for enhanced cyber defense policies. 

To address the challenges related to EU cyber defense policy, 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 Cyber Defence: Protecting Critical Infrastructure & Supporting Strategic Partnerships.

This panel will explore critical issues shaping the future of EU cyber defense, including the evolution of nation-state cyberattacks and the progress made towards the goals set out in the EU’s Cyber Defense Policy. Experts will discuss the challenges of strengthening coordination across member states, lessons learned from recent attacks, and the vital role that private companies play in frameworks like the Tallinn Mechanism. The session will also dive into key obstacles to further collaboration within the EU, and how EU wide legislation like the NIS 2 Directive and Cyber Resilience Act will impact cyber defense efforts. Additionally, there will be a focus on the future of transatlantic cyber defense cooperation, especially in light of the new U.S. administration.

EU Cyber Defense Policy

The EU’s approach to cyber defense has been evolving rapidly, especially in light of the increasingly sophisticated and frequent nation-state cyberattacks. In 2022, the European Commission, alongside the High Representative of the Union for Foreign Affairs and Security Policy, issued a Joint Communication to the European Parliament and the Council on “EU Policy on Cyber Defense.” This policy is designed to boost cyber defense capabilities, improve coordination among EU cyber communities, and reinforce the European Defense Technological and Industrial Base (EDTIB).

The EU's cyber defense strategy is structured around four key pillars:

1. Act stronger together: Fostering greater collaboration among member states to strengthen EU cyber defense.
2. Secure EU defense ecosystem: Ensuring the protection of the EU's defense infrastructure against cyber threats.
3. Invest in cyber defense capabilities: Allocating resources to enhance both defensive measures and technological innovation.
4. Partner to address common challenges: Building partnerships with international allies to tackle shared cyber risks.

This focus on cyber defense was also evident in the proposals put forward by Ursula von der Leyen, President of the European Commission, in her July 2024 address on the Political Guidelines for the Next European Commission (2024-2029). These guidelines emphasize the need for closer collaboration with NATO on defense projects of common interest; developing a Preparedness Union Strategy, with a focus on strengthening EU cyber defense capabilities, coordinating national cyber efforts, securing EU critical infrastructure, and developing a trusted European cyber-defense industry.The guidelines also highlighted the need to engage with key international partners such as Japan, South Korea, New Zealand, and Australia to address global cyber challenges.

Strategic Partnerships 

As Von der Leyen has emphasized, strengthening strategic partnerships is key to enhancing the EU’s cyber defense. Cooperation within the EU, particularly with the private sector, has become increasingly vital in addressing cyber threats. The war in Ukraine has highlighted the importance of trusted providers being ready to respond to major cyber incidents. In 2023, the Tallinn Mechanism was launched to bolster cyber support to Ukraine by creating a new format for donor coordination to deliver the necessary civilian cybersecurity assistance in a streamlined manner. Participating donor countries include Estonia, Canada, Denmark, France, Germany, the Netherlands, Poland, Sweden, the United Kingdom, and the United States. In addition to these 10 countries, the EU and NATO are participating as observers. 

Furthermore, in January 2025, Estonia and Ukraine signed a memorandum to strengthen cooperation on critical infrastructure protection, focusing on risk assessment, threat identification, and infrastructure defense, reinforcing the EU’s efforts to build a more unified and resilient defense framework against cyber threats.

On the global stage, NATO remains one of the EU’s most crucial strategic partners in cyber defense, with Ursula von der Leyen calling out NATO's importance in her guidelines. Especially with the escalation of threats linked to the Russian invasion of Ukraine, the partnership has proven vital in strengthening the collective cyber defense of both entities. 

At the 2023 NATO summit in Vilnius, allies endorsed a new strategic concept that underscores the importance of cyber defense as an integral part of NATO’s overall deterrence and defense posture. This move was complemented by the launch of NATO's Virtual Cyber Incident Support Capability, which aims to provide rapid support to member states in mitigating the effects of cyberattacks. 

Additionally, at the 2024 summit in Washington D.C., allies agreed to establish the NATO Integrated Cyber Defense Center to enhance network protection, situational awareness, and the implementation of cyberspace as an operational domain. This collaboration between the EU and NATO strengthens both entities’ ability to address evolving cyber threats, with a shared commitment to defending critical infrastructure and advancing cyber defense capabilities.

Looking Forward

As these critical discussions unfold at CyberNext BRU, they will shed light on the ongoing efforts and challenges in fortifying the EU's cyber defense, emphasizing the importance of collaboration and innovation in securing the future of Europe’s digital infrastructure. The upcoming panel at CyberNext BRU will be a key opportunity to examine these efforts in detail, with experts exploring how the EU can continue to adapt to evolving cyber threats while strengthening partnerships both within and outside its borders.
