security Using Microsoft Clarity in the UK: 65 Active Firms (2026)
Physical security providers using web analytics sell guarding, key holding and related contracted services across the UK.
For physical security providers, behaviour analytics is less a pure marketing add-on than a signal of operational maturity. The script helps sales and bid teams see where buyers stall on service pages for guarding, key holding, mobile patrol and related contracted work. Adoption tends to point to a direct-enquiry channel alongside referrals, framework relationships and outbound sales. It also suggests enough internal or agency capacity to test enquiry forms, landing pages and local-service content rather than relying only on brochureware. In this sector, the buying centre is usually commercial or operations-led, with website changes needing to reflect licensable activities and the trust cues expected by corporate and public-sector customers.

The UK adoption cohort contains 65 active trading physical security providers running this behaviour-analytics script, with reported headcount of 2,618 across 36 reporting firms. Within detected analytics usage across 1,309 physical security providers, the tool sits joint third at 5.0%, behind the more common general analytics and site-integration deployments. Registered addresses skew towards the South East (23.1%) and London (18.5%), followed by the West Midlands (13.8%), North West (12.3%) and East of England (9.2%). That pattern fits a market where regional guarding operators use digital enquiry journeys, but national procurement and multi-site contracts still pull commercial activity towards larger business centres.
Contracted security work sits under the Security Industry Authority, the regulator of the UK’s private security industry. SIA licensing applies where services are supplied under a contract for services and involve a licensable activity, including manned guarding, key holding and vehicle immobilisation in Northern Ireland. Front-line workers need the relevant licence, while directors, partners, managers and supervisors may also need front-line or non-front-line authorisation where the business supplies security operatives under contract. Behaviour-analytics scripts add a separate governance layer: cookie consent, retention settings and client-side collection need to sit with GDPR and ICO expectations, especially where enquiry forms capture site-risk details or incident context.
Adoption appears likely to remain tied to lead-generation discipline rather than technology fashion. Physical security providers tend to win work through a mixture of local reputation, tendering, referrals and account management, so website analytics has to prove its value in better-qualified enquiries rather than in raw traffic. Privacy pressure may favour simpler measurement setups and clearer consent handling, particularly for firms serving public-sector or regulated corporate buyers. The more mature operators are likely to fold behaviour analytics into wider sales operations, while smaller guarding businesses may keep it as an agency-managed layer on top of fairly standard websites.

Key facts
About 13% of the trading cohort reports turnover above £5M (9 of 65 firms) — the rest sits below that revenue band.
7% of the cohort was incorporated since 2022 (5 firms), so a sizeable share is in its first few filing cycles.
This analytics tool is detected on 5.0% of physical security providers with a detectable analytics system, measured against 1,309 companies in the sector.
The cohort is regionally weighted towards the South East at 23.1%, followed by London at 18.5% and the West Midlands at 13.8%.
83.1% also run a content-management system, while 67.7% also use a tag-management layer; the pattern points to websites managed as lead-generation assets rather than brochure pages alone.
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 worth £12.9 billion in 2024, with physical security accounting for £4.3 billion, or 33%.

How Microsoft Clarity 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.
