Market leader by size
Under 10 employees
90.8% of band
Among Under 10 employees, 3,944 wholesale companies have a detectable Security system, and reCAPTCHA accounts for 90.8% of them. The remaining usage is split across hCaptcha, CleanTalk, Wordfence, Sucuri and smaller tools.
10–50 employees
92.2% of band
In the 10–50 employees band, 1,761 wholesale companies have a detectable Security system. reCAPTCHA accounts for 92.2%, leaving a small remainder across hCaptcha, CleanTalk, Wordfence, Sucuri and the wider long tail.
Over 50 employees
92.2% of band
Over 50 employees is a small detected market, with 180 wholesale companies. reCAPTCHA still accounts for 92.2%, so larger wholesale firms do not show a different pattern from the smaller bands.
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.
