How CDN usage is detected

Methodology

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.

Frequently asked questions

What is the most-used CDN among UK labour supply companies?
Cloudflare is the most-detected CDN among UK labour supply companies, with 87.8% share (910 of 1,036 companies with a detectable system), ahead of Amazon CloudFront (15.8%) and Amazon S3 (9.1%).
How many UK labour supply companies have a detectable CDN?
1,036 of 10,493 actively-trading UK labour supply companies (9.9%) have a CDN detectable from their public website. The remainder either run systems with no public web footprint or none at all, so detected share figures are a conservative floor.
What is a CDN?
A CDN is a content delivery network: a layer that caches and serves website assets so pages, scripts, images and files can be delivered closer to users. For UK labour supply companies, it typically sits in front of recruitment websites, candidate pages and employer-facing content, reducing load on the origin site and helping with bursts of traffic.
How is CDN usage detected?
Firmbase crawls the public website of every actively-trading company in this scope and fingerprints the technologies present — scripts, widgets, booking and checkout flows. A company is attributed to a system when that system's signatures are found; systems with no public web footprint are not attributable, which is why every share figure on this page means share of companies with a detectable system.
Which has more UK labour supply companies, Cloudflare or Amazon CloudFront?
Cloudflare: 910 detected companies versus 164 for Amazon CloudFront, of the 1,036 UK labour supply companies with a detectable CDN.
What is the best CDN for UK labour supply companies?
This page reports observed CDN usage rather than recommendations, so the best CDN depends on site architecture, traffic profile and procurement constraints. Among 1,037 UK labour supply companies with a detectable CDN, Cloudflare has 87.8% (911), Amazon CloudFront 15.7% (163), and Amazon S3 9.1% (94); by size band, Cloudflare leads Under 10 employees at 87.3% of 550 companies, 10–50 employees at 90.2% of 368 companies, and Over 50 employees at 83.2% of 119 companies.
