Under 10 employees
90% of band
With 3,480 companies, this band is the largest Security market segment, and reCAPTCHA leads with 90.0% share. The rest is fragmented across smaller website security and spam-control systems.
10–50 employees
90.9% of band
Across 782 companies, reCAPTCHA leads with 90.9% share. Akismet, hCaptcha, CleanTalk and Sucuri sit in the second tier rather than changing the shape of the market.
Over 50 employees
92.8% of band
Across 69 companies, reCAPTCHA leads with 92.8% share. The largest employee band is the most concentrated of the three, despite having fewer companies.
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.
