How CMS usage is detected

Methodology

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.

Frequently asked questions

What is the most-used CMS among UK security companies?

WordPress is the most-detected CMS among UK security companies, with 79.2% share (1,963 of 2,479 companies with a detectable system), ahead of Wix (9.3%) and Squarespace (3.2%).

How many UK security companies have a detectable CMS?

What is a CMS?

A CMS is the software used to manage a company website’s pages, publishing workflow, templates and content. For UK security companies, it typically supports service pages, contact routes, compliance messaging and local search visibility rather than core operational work.

How is CMS usage detected?

Firmbase crawls the public website of every actively-trading company in this scope and fingerprints the technologies present — scripts, widgets, booking and checkout flows. A company is attributed to a system when that system's signatures are found; systems with no public web footprint are not attributable, which is why every share figure on this page means share of companies with a detectable system.

Which has more UK security companies, WordPress or Wix?

WordPress: 1,963 detected companies versus 231 for Wix, of the 2,479 UK security companies with a detectable CMS.
