Analysis: US Vendor Dominance in European Corporate Web Infrastructure

Date: 7 July 2026 | Author: Chris McCabe | Read Time: $\approx 6$ minutes

CipherCue recently conducted a study focusing on the primary web presence of 19,450 European corporate entities. The goal was to answer a specific, narrow question: Which infrastructure vendor is responsible for serving the company's main website?

The Big Picture: US Hegemony

The research reveals that US-based vendors hold a commanding lead in the European market. In two of the seven sampled countries, US vendors serve the absolute majority of sites:

• United Kingdom: $67.5\%$
• Netherlands: $53.6\%$

In three other markets—Italy, Spain, and France—US vendors represent the plurality (the largest single group), with shares ranging between $44\%$ and $49\%$.

The Cloudflare Phenomenon

Regardless of the country, Cloudflare emerged as the single most prevalent internet-facing infrastructure provider. It isn't just the top US vendor; it outperforms every domestic ISP and European hosting firm in every single market tested.

Regional Breakdown and Data

The distribution of vendor share varies significantly based on the strength of the local hosting industry.

Market Share Comparison

The following table details the distribution across the sampled entities:

The "Domestic Stronghold" Exception

Germany and Poland are outliers where domestic hosting is the dominant force. This is attributed to a robust local ecosystem:

• Germany: Providers like Hetzner, IONOS, STRATO, and Mittwald.
• Poland: Providers such as Home.pl, NetArt, ATMAN, and Beyond.

Technical Nuance: Vendor vs. Geography

It is critical to understand that this study measures vendor attribution, not physical server location.

Because of how Content Delivery Networks (CDNs) work, a user in France visiting a French website served by Cloudflare will likely hit a Cloudflare "Edge POP" (Point of Presence) located physically within France. However, the vendor managing that infrastructure remains a US company.

Scope of Measurement

The study focuses on the internet-facing layer. Here is a checklist of what was not measured:

• Physical data-center coordinates.
• The actual origin hosting provider (hidden behind a proxy/CDN).
• Specific EU sub-processor legal agreements.
• Regional data-plane isolation settings.
• Control-plane administration locations (US vs. EU).

Strategic Implications

"The practical point is not that every European company should leave US infrastructure tomorrow... The point is that sovereignty discussions often start too late in the stack."

While there are valid technical reasons for this trend—such as Cloudflare's unmatched scale in DDoS mitigation—the concentration of risk is a regulatory concern. EU regimes are increasingly worried about:

1. ICT Supply Chain dependencies.
2. Concentration Risk (too many eggs in one basket).
3. Third-country exposure and operational resilience.

Other stacks (IAM, EDR, SIEM, etc.) will be analyzed in future reports.

Methodology Note

The research utilized hosting_attribution observations from CipherCue. The process followed this logic:

# Conceptual workflow for vendor identification
1. Resolve DNS A/AAAA records for apex/www domains
2. Map IP addresses to Autonomous System (AS) via iptoasn.com
3. Classify vendor based on AS operator name (NOT IP geolocation)

Key Constraints:

• Sample Size: 19,450 entities across DE, PL, FR, IT, NL, ES, GB.
• Exclusions: Arbitrary subdomains (e.g., job boards or SaaS endpoints) were ignored to ensure the data reflected the entity's choice, not a third-party SaaS provider's choice.
