Europe’s security does not depend solely on our physical borders and their defense. It rests on something far less visible, and far more sensitive: the digital networks that keep our societies, economies and democracies functioning every second of the day.

Without resilient networks, the daily workings of Europe would grind to a halt, and so too would any attempt to build meaningful defense readiness.

A recent study by Copenhagen Economics confirms that telecom operators have become the first line of defense in Europe’s security architecture. Their networks power essential services ranging from emergency communications and cross-border healthcare to energy systems, financial markets, transport and, increasingly, Europe’s defense capabilities. Without resilient networks, the daily workings of Europe would grind to a halt, and so too would any attempt to build meaningful defense readiness.

This reality forces us to confront an uncomfortable truth: Europe cannot build credible defense capabilities on top of an economically strained, structurally fragmented telecom sector. Yet this is precisely the risk today.

A threat landscape outpacing Europe’s defenses

The challenges facing Europe are evolving faster than our political and regulatory systems can respond. In 2023 alone, ENISA recorded 188 major incidents, causing 1.7 billion lost user-hours, the equivalent of taking entire cities offline. While operators have strengthened their systems and outage times fell by more than half in 2024 compared with the previous year, despite a growing number of incidents, the direction of travel remains clear: cyberattacks are more sophisticated, supply chains more vulnerable and climate-related physical disruptions more frequent. Hybrid threats increasingly target civilian digital infrastructure as a way to weaken states. Telecom networks, once considered as technical utilities, have become a strategic asset essential to Europe’s stability.

Europe cannot deploy cross-border defense capabilities without resilient, pan-European digital infrastructure. Nor can it guarantee NATO interoperability with 27 national markets, divergent rules and dozens of sub-scale operators unable to invest at continental scale.

Our allies recognize this. NATO recently encouraged members to spend up to 1.5 percent of their GDP on protecting critical infrastructure. Secretary General Mark Rutte also urged investment in cyber defense, AI, and cloud technologies, highlighting the military benefits of cloud scalability and edge computing – all of which rely on high-quality, resilient networks. This is a clear political signal that telecom security is not merely an operational matter but a geopolitical priority.

The link between telecoms and defense is deeper than many realize. As also explained in the recent Arel report, Much More than a Network, modern defense capabilities rely largely on civilian telecom networks. Strong fiber backbones, advanced 5G and future 6G systems, resilient cloud and edge computing, satellite connectivity, and data centers form the nervous system of military logistics, intelligence and surveillance. Europe cannot deploy cross-border defense capabilities without resilient, pan-European digital infrastructure. Nor can it guarantee NATO interoperability with 27 national markets, divergent rules and dozens of sub-scale operators unable to invest at continental scale.

Fragmentation has become one of Europe’s greatest strategic vulnerabilities.

The reform Europe needs: An investment boost for digital networks

At the same time, Europe expects networks to become more resilient, more redundant, less dependent on foreign technology and more capable of supporting defense-grade applications. Security and resilience are not side tasks for telecom operators, they are baked into everything they do. From procurement and infrastructure design to daily operations, operators treat these efforts as core principles shaping how networks are built, run and protected. Therefore, as the Copenhagen Economics study shows, the level of protection Europe now requires will demand substantial additional capital.

It is unrealistic to expect world-class, defense-ready infrastructure to emerge from a model that has become structurally unsustainable.

This is the right ambition, but the economic model underpinning the sector does not match these expectations. Due to fragmentation and over-regulation, Europe’s telecom market invests less per capita than global peers, generates roughly half the return on capital of operators in the United States and faces rising costs linked to expanding security obligations. It is unrealistic to expect world-class, defense-ready infrastructure to emerge from a model that has become structurally unsustainable.

A shift in policy priorities is therefore essential. Europe must place investment in security and resilience at the center of its political agenda. Policy must allow this reality to be reflected in merger assessments, reduce overlapping security rules and provide public support where the public interest exceeds commercial considerations. This is not state aid; it is strategic social responsibility.

Completing the single market for telecommunications is central to this agenda. A fragmented market cannot produce the secure, interoperable, large-scale solutions required for modern defense. The Digital Networks Act must simplify and harmonize rules across the EU, supported by a streamlined governance that distinguishes between domestic matters and cross-border strategic issues. Spectrum policy must also move beyond national silos, allowing Europe to avoid conflicts with NATO over key bands and enabling coherent next-generation deployments.

Telecom policy nowadays is also defense policy. When we measure investment gaps in digital network deployment, we still tend to measure simple access to 5G and fiber. However, we should start considering that — if security, resilience and defense-readiness are to be taken into account — the investment gap is much higher that the €200 billion already estimated by the European Commission.

Europe’s strategic choice

The momentum for stronger European defense is real — but momentum fades if it is not seized. If Europe fails to modernize and secure its telecom infrastructure now, it risks entering the next decade with a weakened industrial base, chronic underinvestment, dependence on non-EU technologies and networks unable to support advanced defense applications. In that scenario, Europe’s democratic resilience would erode in parallel with its economic competitiveness, leaving the continent more exposed to geopolitical pressure and technological dependency.

If Europe fails to modernize and secure its telecom infrastructure now, it risks entering the next decade with a weakened industrial base, chronic underinvestment, dependence on non-EU technologies and networks unable to support advanced defense applications.

Europe still has time to change course and put telecoms at the center of its agenda — not as a technical afterthought, but as a core pillar of its defense strategy. The time for incremental steps has passed. Europe must choose to build the network foundations of its security now or accept that its strategic ambitions will remain permanently out of reach.
