security Using Cloudflare in the UK: 671 Active Firms (2026)
Security providers using CDN and web protection technology deliver guarding, keyholding and risk services across the UK.
For contracted security providers, running this CDN and web-protection stack is usually less about software fashion than keeping enquiry routes, quote forms and customer-acquisition pages reachable. It tends to signal a direct-channel posture: someone is paying attention to uptime, automated traffic, analytics tags and form protection, rather than relying entirely on offline sales. Adoption also points to a modest web-operations budget and a marketing or IT owner who can manage DNS, consent choices and website performance. The fit is clearest among mid-market guarding, keyholding, monitoring and mobile-patrol operators, rather than very small firms with brochure sites.

The UK adoption cohort contains 671 actively trading security-services providers running this stack. Reported headcount stands at 9,238 staff, giving the group a visible employment footprint even though many operators remain small by turnover and staffing. Within physical security services, the stack sits at the head of the detected CDN ranking, accounting for 93.6% of use across 717 sector sites. Registered addresses skew toward London at 22.5%, followed by the North West at 15.5%, the South East at 13.4%, the East of England at 11.8% and the West Midlands at 9.4%.
Private security sits under the Security Industry Authority, sponsored by the Home Office, and the licensing question turns on contracted work and licensable activity. Manned guarding, keyholding and similar front-line roles need individual licensing; directors, managers and supervisors can also require front-line or non-front-line licences where the business supplies operatives under contract. For companies running a CDN and form-protection stack, the digital controls are not a substitute for those obligations. They sit alongside procurement, GDPR, cookie-consent and enquiry-handling processes, particularly where websites collect service requests, site-risk details or applicant information.
Adoption appears likely to remain practical rather than fashion-led. Security operators with national contracts and outsourced delivery models tend to keep the stack because uptime, form filtering and basic performance management map directly to enquiry flow and bid credibility. Smaller providers may rely on packaged website builds, so stack choices can move with agencies rather than internal IT teams. Consolidation among guarding and monitoring operators would probably standardise web infrastructure, while licensing and privacy pressure should keep attention on auditability, access control and clean handling of personal information.

Within physical security services where a CDN is detectable, this CDN accounts for 93.6% of detections (671 of 717); the next-nearest system is at 3.5% (25).

The cohort skews towards London at 22.5% (151), followed by the North West at 15.5% (104) and the South East at 13.4% (90).
Website stacks are often content-led: 63.0% also run a content-management system, 45.5% run an analytics tool and 38.6% run bot-challenge tooling.

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. security companies are identified using Firmbase's semantic classification of company activity, built from filings, websites and registered SIC codes rather than SIC codes alone. The detected counts and share figures on this page are computed within that sector cohort, so "share" always means share of security companies with a detectable system — not of all UK companies.
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.
