Market leader by size
Under 10 employees
91.9% of band
Micro employers make up 21,404 companies with a detectable Security system. reCAPTCHA holds 91.9%, with the remainder spread across smaller CAPTCHA, anti-spam, bot-management and site-protection systems.
10–50 employees
92.1% of band
Smaller established B2B firms account for 10,444 companies in this band. reCAPTCHA takes 92.1%, leaving other systems competing for a relatively small remainder.
Over 50 employees
90.6% of band
Larger employers are a smaller cohort at 1,366 companies. reCAPTCHA still leads with 90.6%, so the market remains concentrated even above 50 employees.
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.
