security Using reCAPTCHA in the UK: 974 Active Firms (2026)
Physical security providers using bot defence secure premises, events and assets while filtering automated website enquiries in the UK.
For physical security providers, bot-challenge protection usually sits on quote forms, call-back requests, recruitment pages and client-facing contact routes rather than in the core guarding operation. Adoption tends to signal a direct-channel posture: the firm expects the website to generate service enquiries, but wants to reduce automated spam before it reaches control rooms, sales administrators or branch managers. The buying centre is often shared between operations, marketing and an outsourced web agency. In this sector, the relevant budget is usually modest compared with payroll, fleet and monitoring costs, but it marks a level of web hygiene beyond a brochure site.

The UK adoption picture covers 974 actively trading physical security providers running this bot-defence system. Reported employment across the cohort totals 9,961 people, which is a reminder that the relevant users include staffed guarding and patrol operators, not only web-heavy service businesses. Within physical security services, the system sits at the head of the detected security-tool ranking, accounting for 93.2% of 1,045 detections. Registered-address concentration is highest in London at 20.9%, followed by the South East at 15.8%, the East of England at 12.7%, the North West at 11.8% and the West Midlands at 8.1%.
Private security sits under the Security Industry Authority, an executive non-departmental public body sponsored by the Home Office; GOV.UK describes it as the regulator of the UK’s private security industry. Licensing turns on whether work is supplied under a contract for services and involves a licensable activity. Manned guarding and key holding fall into that frame, with vehicle immobilisation noted for Northern Ireland. For companies running bot-challenge protection, the practical overlap is procurement discipline: enquiry forms, recruitment flows and client contact routes need to support licence-checking, audit trails and operational response rather than simply filtering spam.
Adoption appears likely to remain tied to ordinary website maintenance rather than a separate security programme. Smaller regional operators tend to inherit bot checks through agency-built sites and form plugins, while larger staffed providers are more likely to fold them into wider controls around recruitment, tender enquiries and client contact. The main pressure points are false positives, accessibility, and the loss of usable leads when challenge pages are poorly placed. Over time, selection may become less visible to buyers as hosting, forms and perimeter security are bundled by web suppliers.

Key facts
About 5% of the trading cohort reports turnover above £5M (54 of 974 firms) — the rest sits below that revenue band.
6% of the cohort was incorporated since 2022 (60 firms), so a sizeable share is in its first few filing cycles.
This bot-defence system accounts for 93.2% of the 1,045 physical security providers with a detectable security tool on their websites.
Registered offices skew south: London accounts for 20.9% (204), followed by the South East at 15.8% (154) and the East of England at 12.7% (124).
Website stacks tend to follow local-service lead generation patterns: 84.6% also run a content-management platform, 52.8% run analytics and 35.5% run a contact-form plug-in.
SIA licensing applies where work is supplied under a contract for services and involves a licensable activity, including manned guarding, key holding and vehicle immobilisation in Northern Ireland.
UK security exports were £12.9 billion in 2024, with physical security accounting for 33% of that total, or £4.3 billion.

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