The size split is consistent: reCAPTCHA leads in Under 10 employees at 92.4% of 6,520 companies, in 10–50 employees at 92.2% of 2,797 companies, and in Over 50 employees at 92.0% of 249 companies. Median headcount for the profiled systems sits at 6 or 7, so the visible market skews towards small operators rather than large field-service groups.
The long tail is thin: 8 further systems cover 41 companies, compared with 8,835 on reCAPTCHA. Smaller shares are split between captcha, anti-spam and website-protection systems rather than forming a clear second bloc.

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.
