Market leader by size
Under 10 employees
91.7% of band
Small education companies account for 1,345 companies, with reCAPTCHA taking 91.7% of the band. The remaining share is split across smaller anti-spam, captcha and web-security systems rather than one clear challenger.
10–50 employees
92.1% of band
The 10–50-employee band has 1,010 companies and looks almost identical to the smallest band: reCAPTCHA has 92.1%. Other systems compete for a narrow residual share, including captcha and web-security tools.
Over 50 employees
91.3% of band
The over-50-employee band is much smaller, at 149 companies, but reCAPTCHA still has 91.3%. The remainder is a small field of specialist and secondary security systems.
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.
