Wordfence, Akismet, CleanTalk and Akamai Bot Manager each sit below 4% of detected companies, with 72, 70, 57 and 53 companies respectively. A further 9 systems cover 44 companies, so the remainder is a long tail rather than a balanced split.
reCAPTCHA has the largest share in every headcount band: 81.6% of 1,469 companies under 10 employees, 82.9% of 642 companies in the 10–50 band, and 75.7% of 37 companies over 50 employees. The over-50 employee band is small, so that split is better read as directional than as a full large-retailer benchmark.

Market leader by size
The leading Security system shifts with company size: among UK E-Commerce with under 10 employees, reCAPTCHA leads at 81.6% of the 1,469 with a detectable system; among UK E-Commerce with 10–50 employees, reCAPTCHA leads at 82.9% of the 642 with a detectable system; and among UK E-Commerce with over 50 employees, reCAPTCHA leads at 75.7% of the 37 with a detectable system.
Under 10 employees
81.6% of band
Small e-commerce companies make up 1,469 detections, and reCAPTCHA has 81.6% of the band. The remaining share is split across hCaptcha, Wordfence, Akismet, CleanTalk, Akamai Bot Manager and smaller systems rather than one close challenger.
10–50 employees
82.9% of band
The 10–50 employee band has 642 detections, with reCAPTCHA at 82.9%. hCaptcha and smaller anti-spam or bot-management systems appear as alternatives, but the distribution remains concentrated.
Over 50 employees
75.7% of band
Only 37 detections sit above 50 employees, so individual movements can alter shares. reCAPTCHA still has the largest share at 75.7%, with the rest spread across the smaller named systems and the long tail.
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.
