In European businesses, Cloudflare is the CDN of choice in nine out of ten cases.
The stat stirred discussion in early September. It comes from a British startup that aggregates data on technology stacks—and sells it to security solution providers. Among 44,143 organizations where a CDN was detected, 39,547 were using Cloudflare. That’s 89.6%. Next were Amazon (around 7%), Fastly (3%), and Akamai (1%).
The share attributed to Amazon should be treated with caution: some firms are hosted on AWS without a conscious choice of CloudFront. This issue does not affect Cloudflare, whose penetration rate exceeds 95% in the Netherlands.
| Country | Companies using Cloudflare | Share |
| Netherlands | 7,587 of 7,939 | 95.6% |
| United Kingdom | 15,846 of 17,007 | 93.2% |
| Poland | 2,682 of 2,896 | 92.6% |
| France | 3,456 of 4,008 | 86.2% |
| Italy | 3,126 of 3,661 | 85.4% |
| Germany | 4,650 of 5,715 | 81.4% |
| Spain | 1,576 of 2,001 | 78.8% |
| Ireland | 624 of 792 | 78.8% |
A Quarter of the Web Behind Cloudflare?
The sample isn’t necessarily representative of all types of organizations. It tends to consist of SMEs, a segment for which Cloudflare’s free offering—including DDoS protection and unlimited bandwidth—holds real appeal.
These figures should be read in the context of W3Techs. The latter reports, at its latest update, that 85.1% of sites for which it has knowledge of the reverse proxy use Cloudflare. That would account for about 26% of the Web.
Notably, no European CDN provider is mentioned in this dataset. Behind the scenes, debates linger about potential exposure to the CLOUD Act for content transiting via Cloudflare, given that it terminates TLS sessions to inspect traffic. It’s worth recalling the major outages that Cloudflare has suffered from time to time—outages whose consequences have matched its market share. Two of these incidents, in November and December 2025, prompted the company to launch a “resilience plan.”
