Market leader by size
The leading Security system shifts with company size: among UK Field Services with under 10 employees, reCAPTCHA leads at 89.1% of the 6,755 with a detectable system; among UK Field Services with 10–50 employees, reCAPTCHA leads at 89.1% of the 2,886 with a detectable system; and among UK Field Services with over 50 employees, reCAPTCHA leads at 86.7% of the 264 with a detectable system.
Under 10 employees
89.1% of band
This is the largest detected band, with 6,755 companies. reCAPTCHA accounts for 89.1%, leaving Akismet, CleanTalk, hCaptcha, and smaller systems to compete for a narrow residual share.
10–50 employees
89.1% of band
The 10–50 employee band contains 2,886 detected companies and looks much like the smaller-company market. reCAPTCHA accounts for 89.1%, with the remaining usage spread across a short second tier and a thin long tail.
Over 50 employees
86.7% of band
Only 264 detected companies sit above 50 employees, and reCAPTCHA still accounts for 86.7%. Larger field services companies show a little more room for alternatives, but no other system comes close to its share.
How Security 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.
