IT Services Companies Using reCAPTCHA in the UK: 1,848 Active Firms (2026)
IT services firms using CAPTCHA deliver managed technology support and digital projects while protecting UK website forms from automated abuse.
For IT services and managed services providers, a CAPTCHA layer is a gate on quote, contact, account and support workflows. It tends to sit between marketing operations, service desk intake and web engineering rather than in a standalone security programme. Adoption signals a firm that depends on public web forms for business-to-business lead capture or customer service, and has enough operational volume for spam suppression to matter. The buyer shape is sales-led and service-led: business customers, recurring support contracts, cloud and infrastructure projects, cybersecurity work and digital delivery, with the website treated as part of operational resilience.

Across the UK, 1,848 actively trading IT services and managed services firms are running this CAPTCHA layer on public websites. Reported headcount totals 4,290 people, while median headcount sits at 7, so many adopters remain small service organisations. Within detected security tools in the sector, this system ranks first at 91.7%. Adoption is tilted towards London (20.4%) and the South East (18.9%), followed by the North West (10.7%), East of England (9.3%) and South West (8.2%).
Procurement for this stack usually sits in the grey area between web operations and security assurance. IT services providers often handle client support requests, incident enquiries and sales leads through web forms, so UK GDPR and ICO expectations around privacy notices, cookies, third-party scripts and retention policies are relevant. Accessibility also matters: challenge-response controls can obstruct users if the fallback route is poor. For buyers assessing these firms, CAPTCHA use is better read as website hygiene and abuse reduction, not as evidence of a broader managed-security capability; rate-limiting, monitoring and incident handling still need separate scrutiny.
Adoption appears mature, with most change likely to come from site rebuilds, analytics consolidation and pressure to reduce friction in enquiry journeys. Managed services providers tend to keep form protection because nuisance traffic creates visible operational cost for sales and service teams, but privacy reviews and accessibility testing may push some towards quieter bot-screening methods. The category may also be pulled into bundled hosting, content-management and security packages, making the choice less visible to end users. Scarcity of large scale-ups in the cohort suggests incremental migration rather than a burst of new adoption.
Adoption by company size
Adoption of reCAPTCHA rises with company size across the trading UK IT services companies in this cohort. 1% of the 119,548 companies with under 10 employees run reCAPTCHA (1,190 detected). 28.1% of the 2,157 companies with 10–50 employees run reCAPTCHA (606 detected). 28.7% of the 181 companies with over 50 employees run reCAPTCHA (52 detected). That is a 27.7% gap between the over 50 employees and under 10 employees bands.

Key facts
About 4% of the trading cohort reports turnover above £5M (82 of 1,848 firms) — the rest sits below that revenue band.
5% of the cohort was incorporated since 2022 (97 firms), so a sizeable share is in its first few filing cycles.
This CAPTCHA tool accounts for 91.7% (1,848) of detected security-tool usage in IT services and managed services, among 2,016 companies with a detectable system.
The next three detected security systems each sit below 3%, at 2.7% (55), 2.5% (51) and 2.5% (50).
The cohort is weighted towards southern England: London accounts for 20.4% (377) and the South East for 18.9% (350), followed by the North West at 10.7% (197).
Common co-detections point to conventional marketing-site stacks: 77.9% (1,439) also run a content-management system, 59.4% (1,097) use web analytics and 41.5% (767) use tag management.
Sector tags overlap: cybersecurity appears on 26.9% (498) and telecommunications on 16.9% (312), pointing to suppliers that blend managed IT, security and connectivity work.

How reCAPTCHA 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. IT services 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 IT services 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.
