Media Companies Using Cloudflare in the UK: 1,515 Active Firms (2026)

Updated June 2026

Media publishers using edge delivery and web security technology produce digital content for UK audiences and advertisers.

For media publishers, this stack usually sits between the audience-facing site and the wider ad, subscription and content-management environment. It does the unglamorous work of caching pages, filtering hostile or low-quality traffic, monitoring browser performance and supporting video delivery when audience demand is uneven. Adoption tends to signal a publisher with a direct digital trading model rather than a brochure site: product, engineering, audience development and ad-ops teams all have reasons to care. Buying decisions usually sit with technology and digital product leads, with commercial teams pressing for page speed, campaign reliability and fewer failed sessions during traffic spikes.

UK adoption is sizeable within media and publishing: 1,515 trading companies in this list run the stack on public sites. Reported headcount across firms with employee information totals 2,781. The system sits first among detected CDN technologies for the sector, with an 88.6% share, ahead of the smaller infrastructure alternatives grouped below it. Registration addresses are weighted towards London at 44.4%, followed by the South East at 13.7%, the South West at 8.1%, the North West at 7.5% and the East of England at 7.1%.

Edge security sits in the production path for publishers, so procurement tends to treat it as operational infrastructure rather than ordinary website tooling. The main checks are contractual and procedural: uptime support, data-processing terms for visitor logs, bot-management rules that do not suppress legitimate search or syndication traffic, and incident processes when campaigns or paid content go live. Advertising-funded sites also need close coordination between consent tooling, tag governance and performance monitoring because security rules can change what scripts load, what traffic is filtered and how page latency is measured.

Adoption appears likely to remain tied to audience economics rather than to infrastructure fashion. Publishers with direct subscription journeys, live coverage, video-heavy pages or paid campaign delivery tend to keep edge security close to revenue operations, while smaller editorial sites may accept bundled hosting and simpler protection. Consolidation in content platforms may hide more of the infrastructure choice from non-technical buyers, but engineering and audience teams still need control over caching, bot rules and measurement. The direction looks incremental: fewer bespoke stacks, more packaged controls, and continuing scrutiny of how security settings affect advertising and reader experience.
