Market leader by size
The leading CDN system shifts with company size: among UK Real Estate with under 10 employees, Cloudflare leads at 94.7% of the 3,563 with a detectable system; among UK Real Estate with 10–50 employees, Cloudflare leads at 95.4% of the 703 with a detectable system; and among UK Real Estate with over 50 employees, Cloudflare leads at 95.8% of the 71 with a detectable system.
Under 10 employees
94.7% of band
The Under 10 employees band contains 3,563 companies with a detectable CDN, making it the largest employee segment here. Cloudflare accounts for 94.7%, so other CDNs compete within a small minority of sites.
10–50 employees
95.4% of band
Among 703 companies with 10–50 employees, Cloudflare accounts for 95.4%. Usage is still concentrated, with alternative CDNs present mainly as exceptions rather than segment-specific challengers.
Over 50 employees
95.8% of band
The Over 50 employees band is small at 71 companies with a detectable CDN. Cloudflare accounts for 95.8%, so larger real estate employers show no material shift toward another CDN within this market.
How CDN usage is detected
Company data
Detected companies are joined to UK Companies House records and XBRL accounts data. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.
Detection
Firmbase crawls the public website of actively-trading UK companies and fingerprints the technologies present: tracking scripts, embedded forms, chat widgets, CMS markers and similar signatures. A company is included in this list when one or more of the technology's signatures are found on its site; closely-related variants of the same product are grouped under one name. Detection covers what is visible on the public web — a company using the technology purely internally, with no website footprint, will not appear. Counts are therefore a conservative floor, not a ceiling.
Freshness
Websites are re-crawled on a rolling basis and the underlying company data is refreshed from Companies House continuously; filings appear within days of submission. The list and its statistics are regenerated when the detected cohort moves meaningfully. You can see the last-updated timestamp near the top of the page.
