Europe is no longer treating cybersecurity and digital sovereignty as abstract policy goals—they have become existential priorities. Faced with escalating cyber threats, foreign data dependency, and legal uncertainty, the European Union is doubling down on compliance-first IT infrastructure, strict regulatory enforcement, and sovereign digital alternatives.
From revised laws like NIS2 and DORA to emerging platforms like STACKIT and Gaia-X, a new ecosystem is taking shape—one that prizes data jurisdiction, operational transparency, and trust as much as raw performance.
This transition is already influencing enterprise procurement, reshaping cloud architectures, and prompting security vendors like SentinelOne and SAP to adapt or risk losing ground in a rapidly maturing European digital market.
What triggered Europe’s urgency around sovereign cybersecurity and cloud independence?
Europe’s sovereignty movement is partly a response to past failings—most notably the collapse of Privacy Shield under the 2020 Schrems II ruling. That decision invalidated the legal basis for transatlantic data transfers, exposing European companies to the risk of violating GDPR simply by using U.S.-based cloud services. It also made visible the extent to which Europe’s digital economy depends on foreign cloud providers subject to extraterritorial laws like the U.S. CLOUD Act.
Currently, over 69% of Europe’s cloud market is controlled by American firms, and more than 90% of its digital data is hosted outside EU borders. In a geopolitical environment where digital infrastructure is now seen as critical national security, that dependency has become untenable.
This has pushed both Brussels and national governments to act—moving from regulatory declarations to funding and enabling compliant, sovereign technology ecosystems.
How are NIS2, DORA, and the CRA changing the cybersecurity rules for EU organizations?
Three landmark regulations are driving the compliance-first wave that underpins Europe’s cybersecurity sovereignty push.
The NIS2 Directive, effective from October 2024, expands cybersecurity obligations to over 18 sectors—ranging from energy and transport to telecom and healthcare. It enforces stricter risk management practices, cross-border cooperation mandates, and severe penalties for non-compliance.
The Digital Operational Resilience Act (DORA), rolling out in 2025, is equally transformative for the financial sector. It compels banks, insurers, and asset managers to implement robust ICT risk frameworks—including third-party oversight of cloud service providers, continuous monitoring, and incident response mechanisms.
The Cyber Resilience Act (CRA) goes even further, applying security mandates to any product with digital elements. Manufacturers will be required to patch vulnerabilities and report incidents for years after sale, radically raising the bar for device-level cybersecurity.
Together, these frameworks are not just regulatory burdens—they’re market-shaping forces. Companies unable to demonstrate compliance are increasingly being ruled out of major procurement decisions, especially in the public sector.
What is sovereign cloud, and why is it central to Europe’s cyber resilience ambitions?
At the heart of the EU’s cybersecurity sovereignty movement is the concept of sovereign cloud: infrastructure that guarantees data remains within jurisdictional borders, under the full control of local entities, and outside the reach of foreign surveillance laws.
Sovereign cloud is not about isolation—it’s about trust, transparency, and regulatory alignment. To qualify as truly sovereign, providers must demonstrate several key attributes. First, data residency must be maintained strictly within the European Union or within the borders of individual member states, ensuring compliance with regional jurisdictional boundaries.
Second, the infrastructure must offer legal immunity from extraterritorial data access laws, meaning it cannot be compelled to share data under foreign legislation such as the U.S. CLOUD Act. Third, providers must guarantee operational autonomy, which includes exclusive ownership and control of encryption keys, as well as the ability to enforce strict access protocols. Finally, the platform must hold recognized security certifications, such as ISO 27001 and Germany’s BSI C5, or other equivalent national standards that attest to robust information security practices.
Platforms like STACKIT, operated by Schwarz Digits in Germany, embody this model. By offering GDPR-compliant hosting and partnering with cybersecurity vendors like SentinelOne, STACKIT enables EU customers to deploy advanced AI-based threat defense while maintaining full sovereignty over data, telemetry, and control surfaces.
How are major EU initiatives like Gaia-X, DNS4EU, and EuroStack building sovereign digital infrastructure?
Beyond regulatory enforcement, Europe is putting real capital into building sovereign alternatives to hyperscaler infrastructure. Europe’s push toward cybersecurity sovereignty is being reinforced by several high-impact infrastructure initiatives. Among them is Gaia-X, a flagship Franco-German project launched in 2019 that seeks to create a federated European cloud ecosystem.
Gaia-X mandates adherence to shared principles around data transparency, reversibility, and sovereignty. Despite criticism over its slow rollout, the initiative now includes more than 300 member organizations and is shaping standards in digital identity, data exchange, and service interoperability across the continent. Another cornerstone project is DNS4EU, a Europe-based DNS resolver launched in 2025 to ensure that all domain name queries remain within EU jurisdiction. It offers a compliant alternative to U.S.-controlled services like Google Public DNS and Cloudflare, which previously processed much of Europe’s DNS traffic.
Meanwhile, EuroStack is a bold, long-term vision still in its early stages. The initiative envisions a €300 billion pan-European digital infrastructure program, encompassing sovereign data centers, AI compute capabilities, and secure communication frameworks. Although details are still emerging, EuroStack is widely expected to become a central pillar of the EU’s digital sovereignty roadmap after 2030. Collectively, these initiatives signal a fundamental shift: Europe is no longer content to merely regulate technology—it now aims to own critical parts of the digital stack.
How are enterprises and vendors adapting to Europe’s sovereignty-first digital landscape?
The shift is already reshaping the strategies of global IT providers.
SAP, for example, now offers “on-site” sovereign cloud deployment for sensitive workloads, allowing clients to maintain full control over hardware, software, and compliance configurations. This hybrid model appeals to organizations that want the agility of cloud without compromising legal posture.
SentinelOne, a U.S.-based cybersecurity firm, has begun deploying its AI-native Singularity Platform on sovereign clouds like STACKIT. This enables EU customers to access cutting-edge threat detection, including EDR, CNAPP, and AI SIEM, without exporting telemetry or violating GDPR.
Other hyperscalers are responding cautiously. Microsoft, Google Cloud, and AWS have launched various “sovereign cloud” offerings in partnership with EU-based entities, but these are often limited in scope or criticized for “sovereignty-washing”—providing surface-level compliance without true operational independence.
As more procurement teams demand proof of jurisdictional control, the balance of power may shift toward regional providers and vendors that embrace sovereignty-by-design.
Why are investors and institutional buyers now prioritizing compliance and sovereignty over cost?
Market research suggests that data sovereignty has overtaken cost and performance as a key driver in IT procurement. A 2025 survey of Chief Information Security Officers (CISOs) across the European Union revealed a clear shift in procurement priorities, with 46% of respondents ranking digital sovereignty as their top decision-making factor when evaluating IT and cybersecurity solutions. The emphasis on sovereignty is even more pronounced in Germany, where 58% of CISOs placed it above considerations like cost or performance. In the financial sector—where regulatory compliance and risk exposure are particularly sensitive—54% of firms identified sovereignty as the primary criterion guiding their technology choices.
This shift is especially pronounced in sectors affected by NIS2 and DORA, where non-compliance can lead to reputational damage, financial penalties, or regulatory exclusion.
Public-sector buyers are increasingly constrained by national laws requiring local data processing, making it harder for foreign-controlled vendors to compete unless they offer localized, certifiable solutions.
In this environment, building trust through transparency, auditability, and control is emerging as the new competitive advantage.
What does the future hold for Europe’s cybersecurity and digital sovereignty movement?
Looking ahead, Europe’s sovereignty push is likely to intensify—both in policy scope and infrastructure depth.
New initiatives like the AI Act, which imposes traceability and human oversight for high-risk AI systems, will further tighten the compliance net. Sovereign infrastructure that can host and monitor these AI workloads without external dependencies will become essential.
Moreover, with geopolitical tensions rising and cyber warfare evolving, the importance of digital self-reliance will only grow. Whether it’s controlling encryption keys, auditing AI models, or defending critical infrastructure, Europe is preparing to secure its digital destiny with homegrown, compliant, and sovereign solutions.
In short, sovereignty is no longer optional—it’s the price of trust in the 21st-century digital economy.
