The EU Data Sovereignty Gap That CIOs Need to Close

Data sovereignty in the EU has become table stakes. In industries such as financial services, healthcare, education and critical national infrastructure, CIOs are expected to protect sensitive data and regulated workloads across increasingly distributed environments. This challenge is being amplified in Europe through data governance, cybersecurity, resilience and digital trust requirements in regulations such as GDPR, DORA, NIS2, the EU AI Act, the EU Data Act and others.

But most sovereignty strategies still focus on where the data is stored. That’s no longer where the real risk lies.

The real risk is not just where data sits, but how it moves

Today, data is constantly moving—between clouds, partners, AI models, applications and locations—as digital agility increases. While policies can define where data should reside, they rarely control how it gets there or try to do this at an application level. Neither of these is scalable when you’re running multiple applications and workloads and when traffic can cross borders via unapproved paths without visibility during routing, failover or outages.

This is why many sovereign architectures aren’t always as resilient as they may seem. And business leaders often notice it too late.

Current approaches reveal a gap in enforcing data in motion

The gap is clear: Policies define intent, and setting controls in individual applications is unsustainable, but networks determine reality. Without control at the network layer, sovereignty cannot be guaranteed—or proven.

What many organizations are discovering is that sovereignty cannot be treated as an application-by-application responsibility. In distributed environments, data moves across clouds, partners, AI platforms and jurisdictions through shared network infrastructure. As environments become more connected, manual controls and policy enforcement become increasingly difficult to scale.

This creates a new requirement for digital infrastructure: Sovereignty controls must operate at the same layer where data actually moves. Rather than relying on individual applications to enforce geographic restrictions, organizations need the ability to define approved geographic boundaries once and have those controls consistently enforced across every connection.

In other words, sovereignty must become an operational property of the network itself.

This is exactly the challenge that Equinix Fabric® Geo Zones was designed to address.

With the expansion of Fabric Geo Zones into the EU, organizations can enforce geographic controls directly in the network layer, helping ensure traffic remains within approved boundaries even during failover or rerouting events.

“Residency at rest is straightforward; residency in motion—when a network reroutes around an outage—is where most ‘sovereign’ claims quietly break,” said Scott Crawford, Founder and CEO of 3verest.

“Enforcing sovereignty at the network layer, ensuring that traffic stays inside a defined geographic boundary even during failover, closes a gap that’s otherwise hard to close honestly. A control that blocks non-compliant paths as a property of the network is exactly the kind of proof our customers’ compliance officers want to see in writing.”

Scott Crawford from 3verest also emphasized the role of Equinix and Equinix Fabric Geo Zones:

“Equinix is the default fabric for every one of those vectors. Each new jurisdiction we enter, we expect to be inside an Equinix IBX® data center. Fabric Geo Zones extends our principle—nothing crosses a boundary unseen or unsanctioned into the interconnection layer.”

Enter Fabric Geo Zones for the EU

Define approved paths for data control, confidentiality and compliance

More than 40 customers are already using Fabric Geo Zones to control their traffic flows.

Instead of relying solely on policy-based controls such as jurisdiction, security and compliance, or configuring individual applications such as an ERP system and workloads, for routing data and traffic across a network, organizations using Fabric Geo Zones can enforce sovereignty directly in the network. This supports a range of use cases for digitally agile organizations:

• Connect to multiple clouds for EU-based cloud workloads, using private connectivity within the EU Geo Zone to keep data within the block
• Share partner and ecosystem data, such as research and clinical data, with external organizations in the EU using private connections within an EU-defined geographic boundary
• Keep sensitive training, inference and other AI data flows subject to EU regulations under appropriate geographic controls by connecting the sources, models and compute through EU-based private interconnection

Combined with our neutral, interconnection-rich infrastructure foundation where customers combine in-country control with their choice of networks, clouds, service providers and AI ecosystems, Equinix is the only data center provider that helps CIOs enforce sovereignty at the network layer.

With Fabric Geo Zones, also available in seven individual countries across the world, customers can define where data is allowed to move and ensure traffic stays within approved geographic boundaries, even during failover or rerouting. The result is greater visibility and control over data flows between clouds, partners and applications.

Enforce sovereignty without compromising scalability, resilience or multicloud flexibility

As organizations connect to everything that matters to their business, Fabric Geo Zones provides a way to enforce geographic boundaries for network traffic without compromising scalability, resilience or multicloud flexibility.

This shifts sovereignty from a static concept to something operational and enforceable.

Every connection point is visible as data is en route

Customers can move from controlling where data sits to controlling how it flows. Sensitive data can be kept within the EU zone. Critical exchanges can avoid the public internet. Data movement across providers becomes visible and governed. In hybrid multicloud environments, this creates consistent control across every connection point.

Control even when complexity increases as environments become more distributed

In distributed AI environments, that control extends further, defining where data and workloads are allowed to move, and which models, agents and partners they can interact with. With Network Edge, Equinix’s portfolio of virtual networking devices, these controls extend across edge-to-cloud architectures, closing gaps across increasingly fragmented environments.

Meet audit and compliance requirements with actual proof

Just as importantly, Fabric Geo Zones strengthens compliance. Instead of assuming that requirements are met, organizations can enforce and demonstrate control over data movement. They can validate their network paths, explain their architectures with evidence, and reduce exposure to jurisdictional risk across multiple providers.

This is especially critical in the EU, where regulatory expectations continue to increase.

Sovereignty as an inherent property of the network

Fabric Geo Zones also addresses one of the risks that businesses most often overlook: network behavior under stress. During failovers or congestion, their traffic can be rerouted across borders without them knowing it. With Fabric Geo Zones, traffic follows approved paths, or it doesn’t move at all. Non-compliant routes are blocked at the network layer, making sovereignty an inherent property of the network rather than a best-effort outcome.

This not only reduces compliance risk but helps optimize performance by removing unnecessary routing and bottlenecks.

The timing matters. Across the EU, governments are repatriating sensitive workloads, regulatory frameworks are evolving and dependence on external technology remains high. At the same time, AI is amplifying both the scale and sensitivity of data movement. The expansion of Fabric Geo Zones into the EU helps ensure that businesses are prepared for these challenges.

Sovereignty is no longer just about control; it’s about balancing resilience and agility

CIOs no longer have to choose between digital sovereignty and digital agility.

Their organizations can scale and be resilient while adapting to regulations, technologies and business demands. But doing so requires a broad view of sovereignty. Data sovereignty doesn’t stop at storage. In distributed environments, data is constantly in motion, and risk moves with it. Sovereignty comes from controlling data in motion, and being able to prove that control.

Sovereignty is entering a new phase. For years, organizations focused on where data was stored. Increasingly, regulators, customers and business leaders are asking a different question: Can you prove how data moves?

As AI ecosystems become more distributed and organizations connect across clouds, partners and jurisdictions, controlling data in motion will become just as important as controlling data at rest. The organizations that can enforce and demonstrate that control without sacrificing agility will be best positioned to meet regulatory requirements, build digital trust and compete in an increasingly connected economy.

By providing visibility and control over how data moves, Fabric Geo Zones helps ensure that data remains within approved geographic boundaries while maintaining the connectivity and performance digital organizations require.

The next step for CIOs is to assess how data moves across clouds, partners and applications, identify sovereignty gaps, and ensure controls extend beyond data at rest to include data in motion. Those that can do so without sacrificing agility will be better positioned to comply, innovate and compete.
