Threat Intelligence Companies Using Cloudflare in the UK: 90 Active Firms (2026)
Threat intelligence providers running edge security infrastructure collect, enrich and deliver cyber-risk signals for UK buyers.
Buying decisions usually sit with security engineering, platform operations and commercial teams rather than a general web-marketing owner. For threat-intelligence providers, a managed edge stack protects research portals, enrichment APIs, customer dashboards and high-availability content, while bot mitigation helps reduce scraping and abusive traffic against indicator feeds. Adoption tends to signal a business selling to enterprise, government or security-service customers that expect uptime commitments, low-latency access and auditable controls. It also points to an organisation with enough operating maturity to coordinate research analysts, engineers, customer delivery and revenue teams around the same public web surface.

UK adoption within this threat-intelligence cohort covers 90 active companies. The stack ranks first in the sector’s detected CDN category, with 85.7% share against a denominator of 105; other content-delivery and storage services appear as secondary or overlapping infrastructure. The regional skew is clear: London accounts for 40.0% of adopters, followed by the South East at 17.8%, the North West at 8.9%, the West Midlands at 6.7% and the East of England at 5.6%. Reported headcount across the employment footprint totals 1,523, which fits a specialist market rather than a broad small-business web-hosting pattern.
Procurement for these adopters is likely to be more security-led than marketing-led. Buyers using threat feeds, fraud scoring or security analytics tend to ask how edge logs, browser signals and customer telemetry move through enrichment pipelines, who can access them, and how incident-response evidence is retained. Managed edge security also introduces supplier-concentration questions: the public website, API endpoints and anti-bot controls may depend on the same external platform, so resilience assessments usually cover failover, contractual support, audit trails and change control. Where customers include government or regulated enterprises, privacy, data-location and subcontractor commitments tend to sit alongside performance testing.
Adoption appears likely to remain tied to direct-channel maturity rather than to sector fashion. Threat-intelligence firms with public research content, customer portals and enrichment APIs have practical reasons to keep edge security close to their go-to-market stack, especially where bot traffic, scraping and uptime risk affect customer trust. Smaller specialists may stay with bundled hosting or lighter web protection until enterprise procurement forces a move. The scarcer scale-up cohort tends to treat managed edge controls as part of customer assurance, not just website performance, which should keep the category sticky even as vendors bundle more adjacent security functions.
What’s in the file
One row per company, 50+ columns — everything below plus each company’s verified directors, from Companies House filings.
Company data
Verified directors — included
Active director count is the full Companies House board, so it can be higher than the number of names listed — we leave out nominee and formation-agent directors, who aren’t worth contacting. It’s blank for the small number of companies whose officers we haven’t fetched yet.
You’re charged per business, not per row. Where a business trades through several registered companies you get every one, and the Group Primary column marks one row per business — filter to those and the count matches your invoice. Rows sharing a website are not automatically one business: franchises and multi-site operators each count separately, and where names don’t prove a relationship we count them apart rather than guess.
Adoption by company size
Adoption of Cloudflare rises with company size across the trading UK threat intelligence companies in this cohort. 53.1% of the 96 companies with under 10 employees run Cloudflare (51 detected). 59.3% of the 54 companies with 10–50 employees run Cloudflare (32 detected). That is a 6.2% gap between the 10–50 employees and under 10 employees bands.

The cohort overlaps with adjacent technology categories: 42.2% (38) are tagged as SaaS, 31.1% (28) as IT Services & Managed Services and 20.0% (18) as AI & Machine Learning.

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. threat intelligence 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 threat intelligence 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.
