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 recruitment companies?
Cloudflare is the most-detected CDN among UK recruitment companies, with 88.2% share (1,462 of 1,658 companies with a detectable system), ahead of Amazon CloudFront (15.2%) and Amazon S3 (9.2%).
How many UK recruitment companies have a detectable CDN?
1,658 of 26,262 actively-trading UK recruitment companies (6.3%) 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, or content delivery network, is a system that serves website assets such as pages, images and scripts from cached locations rather than relying only on the origin web server. For UK recruitment companies, it sits in the public website stack and supports faster delivery of job pages, candidate content and employer-facing pages.
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 recruitment companies, Cloudflare or Amazon CloudFront?
Cloudflare: 1,462 detected companies versus 252 for Amazon CloudFront, of the 1,658 UK recruitment companies with a detectable CDN.
What is the best CDN for UK recruitment companies?
This page publishes observed CDN usage among UK recruitment companies, not recommendations.
