Under 10 employees
91.5% of band
Under 10 employees is the main volume band, with 508 companies and Cloudflare on 91.5%. Amazon CloudFront and Amazon S3 form the smaller alternatives in a market where most detected usage sits with one system.
10–50 employees
92.4% of band
10–50 employees covers 143 companies, with Cloudflare at 92.3%. The pattern is close to the smallest band, suggesting mid-sized insurance firms do not shift far away from the same CDN mix.
Over 50 employees
81.8% of band
Over 50 employees is a small detected cohort, with 11 companies and Cloudflare at 81.8%. The lower share leaves slightly more room for other systems, but Cloudflare still leads the band.
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.
