B2B Using Microsoft Entra ID in the UK: 77 Active Firms (2026)
B2B companies running cloud identity management sell goods or services to other organisations while operating UK-facing digital estates.
For B2B suppliers, the identity layer sits between customer-facing portals, employee access and partner administration. Running this cloud identity system usually signals that authentication is no longer a side feature owned only by web development: security, operations and revenue teams all have a stake in access rules, administrator permissions and account recovery. The fit is clearest among mid-market sellers with repeat business customers, support desks, channel partners or procurement-led accounts. Engagements tend to involve directory integration, role design and migration work, so the buyer is more often an operations or IT owner than a pure marketing team.

UK adoption is still a relatively selective pattern: 77 active trading B2B companies run this identity stack, and the same group reports 1,360 employees between them. Within the 516-company authentication comparator set, the system sits third by detected use, at 14.9%. The registered-office skew is towards London, with 33.8% of adopters, followed by the South East at 15.6%, the South West at 10.4%, the North West at 9.1% and the East of England at 6.5%. That points to a buyer base weighted towards services, software and specialist commercial suppliers rather than a broad small-business default.
B2B identity procurement sits inside a mixed regulatory setting rather than a single UK licensing regime. The underlying activity still matters: financial services, telecoms, professional services and data-processing businesses face different rulebooks and customer due-diligence expectations. For marketing and sales operations, the ICO position is central. PECR covers direct marketing by calls, electronic mail and fax; UK GDPR still applies where personal data is processed, including business-contact records; and live B2B calling needs screening against CTPS and TPS where objections or corporate registration apply. Identity tooling therefore becomes part of access governance as much as website infrastructure.
Adoption appears likely to deepen where B2B suppliers run customer portals, reseller access or managed-service operations. Smaller users tend to start with staff access and administrator controls, then extend identity governance towards customers once support, billing and onboarding workflows become harder to manage manually. The constraint is implementation capacity: directory clean-up, role design and exception handling are not trivial for lean teams. Vendor consolidation may also make the stack less visible to buyers, with identity bundled into broader workplace, security or cloud contracts rather than bought as a separate project.

Key facts
About 15% of the trading cohort reports turnover above £5M (12 of 77 firms) — the rest sits below that revenue band.
6% of the cohort was incorporated since 2022 (5 firms), so a sizeable share is in its first few filing cycles.
Among 516 B2B firms with a detectable authentication system, this identity tool accounts for 14.9% (77), behind two larger login options at 48.1% (248) and 20.3% (105).
London accounts for 33.8% (26) of the cohort, followed by the South East at 15.6% (12) and the South West at 10.4% (8).
Site stacks are mixed: 54.5% (42) also show an edge-security technology, 50.6% (39) a tag manager, 46.8% (36) a content-management system and 45.5% (35) analytics.
Advanced Manufacturing and SaaS are the two largest overlapping sector tags at 20.8% (16) and 19.5% (15), with Construction and Wholesale & Distribution both at 10.4% (8).
ICO guidance says B2B emails or texts to corporate bodies do not need PECR consent, but senders must identify themselves, provide a valid opt-out address and keep UK GDPR in scope where personal data is processed.

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