Threat Intelligence Companies Using Yoast SEO in the UK: 57 Active Firms (2026)
Threat intelligence companies running SEO technology in the UK monitor digital risk, cyber threats and adversary activity for commercial customers.
For threat-intelligence providers, this SEO stack usually sits behind explainer libraries, research notes, breach-monitoring landing pages and gated reports aimed at security, risk, compliance and technology buyers. Adoption signals a direct-channel posture rather than pure partner referral: marketing teams need controllable page templates, search metadata, schema handling and low-friction publishing for fast-moving threat topics. The buyers these firms pursue are mostly B2B and public-sector teams with longer diligence cycles, so the website has to carry evidence of analyst capability, data handling discipline and procurement fitness before a sales conversation begins.

Across the UK, 57 threat-intelligence companies are actively trading and running this SEO technology. It is the most common detected SEO system in the category, accounting for 73.1% of SEO tooling, with other systems at 11.5%, 10.3%, 3.8% and 1.3%. The registered-office skew is also clear, with London at 42.1%, the South East at 21.1%, the North West at 8.8%, the East of England at 7.0% and the West Midlands at 5.3%. Reported headcount across adopting firms totals 961, which fits a market where specialist teams outnumber large corporate platforms.
Search-led acquisition in threat intelligence brings regulated-adjacent obligations into an otherwise marketing-facing stack. Landing pages, trackers and gated reports can capture work emails, IP signals and security interests, so GDPR and ICO expectations around consent, retention and profiling sit close to day-to-day publishing. Public-sector and enterprise buyers also tend to review hosting, access control, incident response and subcontractor positions before approving supplier portals or demos. Where SEO tooling is attached to a content-management stack, procurement risk is less about the plugin itself and more about update discipline, permissions and the surrounding analytics estate.
Adoption appears likely to remain tied to content operations rather than deep security product architecture. Threat-intelligence providers need pages that can be changed quickly when adversary behaviour shifts, but buyers still expect restraint: over-optimised copy can sit awkwardly beside claims about analyst judgement and confidentiality. Firms with small marketing teams tend to favour familiar publishing stacks, while more mature suppliers may move optimisation, consent management and content governance into a more controlled web platform. Consolidation in the supplier stack is plausible, though replacement cycles are likely to be governed by security review and website rebuilds rather than fashion.
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 Yoast SEO varies by company size across the trading UK threat intelligence companies in this cohort. 37.5% of the 96 companies with under 10 employees run Yoast SEO (36 detected). 31.5% of the 54 companies with 10–50 employees run Yoast SEO (17 detected). That is a 6% gap between the 10–50 employees and under 10 employees bands.

Key facts
About 10% of the trading cohort reports turnover above £5M (6 of 57 firms) — the rest sits below that revenue band.
10% of the cohort was incorporated since 2022 (6 firms), so a sizeable share is in its first few filing cycles.
The selected SEO system has 73.1% (57) detected share among 78 threat-intelligence firms with a detectable SEO tool, ahead of the next two systems at 11.5% (9) and 10.3% (8).
Every firm in the cohort also runs a CMS platform detected at 100.0% (57), which fits a sector that publishes threat research, advisories and lead-generation content on public websites.
Tag-management tooling appears on 71.9% (41) of sites, while web analytics appears on 52.6% (30), so measurement adoption is common but not universal across this SEO-running threat-intelligence cohort.
Registered offices skew towards London at 42.1% (24) and the South East at 21.1% (12), with the North West next on 8.8% (5).
Sector tags overlap: Cybersecurity covers 100.0% (57), IT Services & Managed Services 40.4% (23), SaaS 31.6% (18), Physical Security Services 19.3% (11), and AI & Machine Learning 10.5% (6).

How Yoast SEO 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.
