B2B Companies Using FingerprintJS in the UK: 53 Active Firms (2026)
B2B companies running browser fingerprinting use client-side signals to recognise devices, manage fraud risk and protect digital journeys in the UK.
Client-side device recognition tends to appear where a B2B firm has more at stake than a brochure site: account logins, quote requests, gated data products, partner portals or paid digital workflows. Buying centres usually sit between product, security, revenue operations and web engineering, rather than in a single software-procurement lane. Adoption signals a company with enough digital volume to care about repeat devices, suspicious sessions and attribution quality, but not necessarily an enterprise-sized risk function. Engagements tend to be operational add-ons to the web stack, bought to reduce manual review, protect conversion paths and give commercial teams cleaner evidence about online intent.

Across the UK, the detected browser-fingerprinting adoption cohort contains 53 active trading B2B companies, with reported employment of 308 people across reporting firms. The system sits at 100.0% of the relevant browser-fingerprinting category, reflecting a narrow technology lens rather than a general B2B market view. Regional registrations are spread across Yorkshire and The Humber and London at 18.9% each, followed by East of England and North West at 11.3% each, then South East at 9.4%.
B2B activity in the UK is not governed by a single licence regime; obligations follow the underlying activity, such as financial services, telecoms, data processing or professional services. For companies running client-side device recognition, the practical questions sit around notice, lawful basis, retention, access controls and the point at which browser or business-contact signals become personal data under UK GDPR. The ICO's PECR guidance also matters where adoption is tied to sales journeys: direct marketing by live call, automated call, electronic mail or fax is covered, B2B senders to corporate subscribers still need clear identity and opt-out routes, and live calling requires CTPS and TPS screening.
Adoption appears likely to remain concentrated among B2B firms with logged-in journeys, quote engines, partner portals and inbound acquisition teams, rather than across the whole business-services base. The pattern tends to favour companies that already run layered web stacks: content management, edge security, analytics tags, bot checks and form-handling tools. Pressure may come from privacy review, marketing consent scrutiny and procurement teams asking how device signals are collected, retained and explained. A more common path is gradual bundling into fraud, risk and conversion-measurement workflows, with specialist use cases persisting where false positives have a direct commercial cost.
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 FingerprintJS rises with company size across the trading UK B2B companies in this cohort. 0% of the 76,784 companies with under 10 employees run FingerprintJS (28 detected). 0.1% of the 31,788 companies with 10–50 employees run FingerprintJS (25 detected). 0.1% of the 3,773 companies with over 50 employees run FingerprintJS (2 detected). That is a 0.1% gap between the over 50 employees and under 10 employees bands.

Key facts
About 9% of the trading cohort reports turnover above £5M (5 of 53 firms) — the rest sits below that revenue band.
7% of the cohort was incorporated since 2022 (4 firms), so a sizeable share is in its first few filing cycles.
Browser fingerprinting appears as a single detectable system in this B2B slice, recorded at 100.0% (53) of companies with a detectable browser-fingerprinting system.
The stack skews toward content-led websites: 88.7% (47) also run a content-management system, while 50.9% (27) also use an edge-security or CDN service.
Analytics and anti-bot controls often sit beside fingerprinting, with 45.3% (24) also running web analytics and 41.5% (22) also running a bot-challenge service.
Registered-office concentration is split between Yorkshire and The Humber and London, each at 18.9% (10), ahead of the East of England and North West at 11.3% (6) apiece.
ICO guidance keeps B2B marketing inside PECR for live or automated calls, electronic mail and fax; UK GDPR still applies where personal data is processed.

How FingerprintJS 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. B2B 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 B2B 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.
FingerprintJS is a trademark of its respective owner. Firmbase is not affiliated with, sponsored by, or endorsed by the trademark owner.
