Your data is a strategic asset. You’re giving it away for free.

Data is the raw material of modern cybersecurity. Without deep telemetry, you cannot understand your threat picture. When that telemetry flows to non-European platforms, someone else owns the intelligence – and you are funding a competitive advantage that works against you.

Key takeaways

✓ Data is a strategic raw material – comparable to lithium or cobalt

✓ A data centre in Europe running non-European software is not sovereignty

✓ Who owns your security telemetry determines who has threat intelligence advantage

✓ European cybersecurity platforms are built from European data, calibrated to European threats

Data is the new raw material

The analogy is imprecise but directionally right: data is to the digital economy what lithium or cobalt is to the physical one. AI systems are built from it. Cybersecurity platforms depend on it. The quality of your threat intelligence is a direct function of the volume and depth of security telemetry being processed – and who processes it.

When European organisations run their security operations on non-European platforms, their telemetry – data about their own networks, users, and vulnerabilities – flows to non-European systems. The intelligence derived from that data is owned by non-European companies. In some cases, it is shared with allied governments through frameworks that exclude European institutions.

This is not theoretical. Research demonstrating AI’s ability to discover zero-day vulnerabilities at scale was initially shared with ~50 US-jurisdiction organisations. No European institutions received equivalent access. European defenders were behind before they knew the threat existed.

Sovereign washing

The most persistent misconception: a data centre in Europe equals data sovereignty. It does not.

Modern cloud architecture is elastic. An orchestration layer routes queries dynamically across jurisdictions. Legal instruments like the US CLOUD Act allow US authorities to access data held by US companies regardless of where it physically sits. An organisation running American software on European hardware has not achieved sovereignty. It has changed where a hard drive is located.

Real sovereignty requires European ownership of the application layer – the software that processes data, the AI models that learn from it, and the security systems that protect it. WithSecure has made this a deliberate operational commitment: R&D and service delivery consolidated under EU jurisdiction, 100% European ownership, data governed entirely within European law.

The telemetry advantage

Security platforms are increasingly built on AI models trained on historical telemetry. Detection quality – distinguishing malicious from normal behaviour, identifying novel attack patterns, surfacing relevant signals – depends directly on the richness of that training data.

A European platform processing security events from European networks builds models calibrated to European threat patterns. The attack priorities facing a Finnish financial institution or a German manufacturer are not identical to the priorities that shaped a US-headquartered platform’s training data. Specificity matters.

WithSecure processes 2.7 trillion security events per year, identifying 80 million attacks – threat intelligence of genuine depth, entirely under European jurisdiction. That telemetry is not just a product input. It is the foundation for threat intelligence that is actually relevant to European organisations.

What to do about it

Moving towards data and digital sovereignty is incremental, not binary. Start here:

• Audit your data flows. For each major platform, identify where data is processed, under whose jurisdiction, and what access rights the provider holds.
• Apply the same lens to your security stack. Security tools have privileged access to your most sensitive operational data. If they are non-European, that data leaves your jurisdiction.
• Prefer European alternatives where capability is equivalent – and on capability, the case for European cybersecurity is strong. European platforms rank first in customer satisfaction, ease of use, and functionality among mid-market peers.
• Build incrementally. One workload moved to a European platform creates momentum. You do not need to switch everything at once.

The GDPR paradox

GDPR applies equally to all companies operating in Europe. That means reforms designed to help European companies use data for AI development also benefit the largest non-European incumbents. The intended floor becomes an unintended subsidy.

Getting this balance right – enabling European companies to build competitive AI-powered products on European data, without inadvertently advantaging non-European platforms – is one of the defining policy challenges ahead. European organisations that engage with that debate, and make deliberate buying choices in the meantime, are part of the solution.

Frequently Asked Questions

Q: Does GDPR protect my data from non-European access?

GDPR limits misuse of personal data, but does not override instruments like the US CLOUD Act, which can compel US companies to provide data to US authorities regardless of server location.

Q: Why does security telemetry matter for sovereignty?

Telemetry trains the AI models that power detection. When it flows to non-European providers, the resulting intelligence may not reflect European threat priorities – and you may lack access to what your own data reveals.

Q: Is it realistic to move to European-only technology?

Not immediately, but the direction matters. Audit your data flows, substitute where capability is equivalent, and build incrementally. European cybersecurity platforms are fully competitive.

Digital sovereignty starts with a decision

European organisations are contributing strategic value to non-European platforms at scale, continuously, and largely without deliberate choice. The alternative is not isolation – it is intentionality. Know where your data goes. Prefer platforms that keep it under European governance. The data you generate is yours. Start treating it that way.
