Under 10 employees
84.4% of band
At 15,604 companies, the under-10 band is the largest detected Security cohort; reCAPTCHA accounts for 84.4%. The other 18 systems compete for a relatively small remainder across small B2C operators.

80% of band

87.1% of band
The over-50 employee band contains 988 companies with a detectable Security system. reCAPTCHA accounts for 87.1%, leaving bot-management, CAPTCHA and site-security alternatives with a narrow combined 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.
