Companies Using Cloudflare in Leeds: 1,722 Active Firms (2026)
Companies using web security and content-delivery infrastructure operate public websites for commerce, services and operations across Leeds.
Adoption usually points to a company with a website that has become operational infrastructure rather than brochureware. The stack sits between hosting, security, marketing technology and customer service, handling content delivery, request filtering, uptime protection, bot controls and page-level telemetry. In Leeds, the clearest users tend to be larger SMEs and mid-market operators selling online, taking enquiries through secure forms, publishing regular content or supporting account-based service journeys. Buying responsibility is often shared: marketing wants speed and measurement, web teams want cache and deployment control, and security owners want a defensible perimeter without moving the whole estate.

Leeds has 1,722 trading companies running this web security and content-delivery stack, making the page a view of adoption rather than a list of suppliers. Reported employment across the cohort is 4,877 people, although the footprint is likely concentrated in firms where the website supports sales, service delivery or operational workflows. The commercial mix is not only software or online retail: local adopters also include trades, distribution, manufacturing and construction operators that need fast product pages, lead-generation journeys, partner portals or protected web applications.
Traffic-routing, security filtering and browser telemetry put procurement across marketing operations, web operations and cyber-security rather than a single budget holder. Where contact forms, account areas, behavioural analytics or bot checks process identifiable users, GDPR and ICO guidance make consent, logging periods, processor terms and incident handling part of the operating model. For public-facing commerce and service sites, the practical market structure is also shaped by agency retainers and managed-hosting relationships: many Leeds adopters will not operate the stack directly, but still carry responsibility for privacy notices, availability expectations and supplier oversight.
Adoption appears likely to deepen where websites sit closer to revenue, service delivery or operational resilience. Smaller users tend to start with performance and basic protection, then add stricter traffic controls as forms, account areas and campaign landing pages carry more risk. The constraint is organisational as much as technical: many Leeds firms still rely on external agencies, so migration and configuration choices may follow retainer cycles rather than internal architecture plans. Consolidation across hosting, security and analytics also points to fewer standalone buying decisions, with website infrastructure treated more like a governed operating layer.

How Cloudflare 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.
