Real company detection
Every visit resolved to a real account with a transparent confidence score. You're only billed on medium+ — never for noise.
Website visitor identification reveals the organisations behind your anonymous website traffic. For B2B, the useful unit is the company. Here's how it works, what's GDPR-friendly, and how to choose a tool.
In one sentence:
Website visitor identification is the practice of revealing which companies visit your website — by name, domain and the pages they view — turning anonymous traffic into named, actionable accounts.
The basics
A small script records each visit. Network signals (IP, ASN, reverse DNS) are mapped to an organisation, then enriched with public firmographics — industry, size, HQ. A confidence score tells you how sure the match is.
Company-level identification works without storing personal data, which is why it can be GDPR-friendly on a legitimate-interest basis.
Why it matters
Most B2B sites identify 0% of their traffic by name. Visitor identification turns that anonymous traffic into named accounts for ABM, outbound prioritisation and attribution — even when visitors never fill a form.
Capabilities
Every visit resolved to a real account with a transparent confidence score. You're only billed on medium+ — never for noise.
Industry, size, HQ, founded year and tech hints arrive with each lead, from public sources. No separate enrichment tool.

Company vs person
There are two flavours of visitor identification. Company-level resolves the organisation behind a visit (e.g. 'Acme GmbH') from network signals — company-level, no personal data, GDPR-friendly. Person-level attempts to name the individual via third-party identity graphs; it is mostly a US practice and raises clear privacy obligations in Europe.
Nalloo is deliberately company-level. For EU and global B2B, that's the defensible choice: you still get actionable intent — which accounts are interested and what they viewed — without handling PII or asking for consent.
FAQ
No. Analytics counts anonymous sessions and behaviour; visitor identification names the companies behind that traffic so sales and marketing can act on specific accounts.
It varies by traffic. Corporate networks resolve well; mobile and consumer ISPs less so. Nalloo attaches a confidence score to every match and only bills medium-or-higher results.
Company-level identification (company-level, no PII) is generally done on a legitimate-interest basis and doesn't require a consent banner. Person-level identification is treated differently. Not legal advice.
No. Nalloo identifies companies, not people. It never stores personally identifiable information.
Yes. Nalloo identifies companies (not natural persons), stores no personal data; IP addresses are processed hashed, inside the EU. This page is informational and not legal advice.
