B2B Using Vanta in the UK: 99 Active Firms (2026)
B2B companies using compliance tools sell products or services to organisations in the UK while signalling security and data-governance maturity.
Compliance automation sits with security, legal and revenue teams rather than a single IT owner, because its commercial value is in shortening procurement reviews and producing evidence for customer risk teams. Among B2B suppliers, running this kind of tooling usually signals recurring enterprise or mid-market sales, a security function with named ownership, and enough buyer scrutiny to justify formal controls, attestations and audit workflows. The adoption pattern is less about generic website trust badges and more about sales readiness: firms need consistent answers for due-diligence questionnaires, contract renewals and data-processing conversations.

Across the UK, 99 active B2B companies are running this compliance platform. The reported employment footprint is 1,645 staff, pointing to a user base made up mostly of small specialist teams rather than very large employers. Within security tooling used by the wider B2B category, the platform accounts for 0.3% across a 33,194-company denominator, placing it behind common bot-protection and web-security utilities. Registered-office concentration is London-weighted: London accounts for 54.5% of the cohort, followed by the South East at 12.1%, the North West at 7.1%, the East of England at 5.1% and the East Midlands at 4.0%.
For companies running security-assurance tooling, procurement expectations tend to overlap with privacy obligations. B2B is not a single licensed industry in the UK, so controls vary by activity: financial services, telecoms, data processing and professional services each bring different assurance burdens. The ICO’s PECR guidance treats direct marketing by calls, email and fax as regulated activity, while noting that the electronic-mail consent rule does not apply to corporate subscribers. Senders still need clear identity, a valid opt-out route and UK GDPR handling for personal business-contact data. Live marketing calls also require CTPS and TPS screening where relevant.
Adoption appears most likely where sales teams face repeated security questionnaires and where security ownership has moved beyond the founder or generalist operations role. Many users will remain relatively small, because a formal assurance workflow can be useful before finance or HR systems reach enterprise complexity. Some migration pressure may come from customer procurement portals and cyber-insurance requests, but bundling by adjacent governance, risk and privacy tools could make standalone choices less visible. The cohort therefore looks more like a procurement-readiness signal than a broad security-operations market.

Key facts
About 12% of the trading cohort reports turnover above £5M (12 of 99 firms) — the rest sits below that revenue band.
17% of the cohort was incorporated since 2022 (17 firms), so a sizeable share is in its first few filing cycles.
Within the detected security category, the compliance-tool-running B2B cohort accounts for 0.3% (99) of 33,194 companies with a detectable system.
Security-category detection is concentrated in bot-checking and anti-spam tools, with the three largest detected systems at 91.9% (30,498), 2.5% (824) and 2.5% (821).
London accounts for 54.5% (54) of the cohort, followed by the South East at 12.1% (12) and the North West at 7.1% (7).
The sector overlap is SaaS 68.7% (68), AI & Machine Learning 34.3% (34) and Startup 27.3% (27), so the cohort skews towards software-led suppliers.
ICO guidance says B2B emails or texts to corporate bodies do not need PECR consent, but senders must identify themselves and provide a valid opt-out address.

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