Among European Companies That Use a CDN, Nearly 9 in 10 Use Cloudflare
A data analysis of European companies reveals that nearly 90% of those using a content delivery network (CDN) rely on Cloudflare. The report highlights the significant market dominance of Cloudflare compared to competitors like Amazon, Fastly, and Akamai.
Why it matters
The high concentration of web traffic through a single provider creates a systemic dependency, where outages at the CDN level can impact a vast portion of the internet.
A content delivery network sits in front of a website. Requests hit the CDN's edge servers first, which serve cached content, terminate TLS, filter traffic, and pass the rest back to the origin. That means the CDN is a shared dependency: if it goes down, every site behind it goes down together, whether or not those sites have anything else in common.
I went through CipherCue's tracked European companies to see which CDN fronts their websites. Of the 44,143 companies where we detected a CDN at all, 39,547 are behind Cloudflare. That is 89.6%.
