More than a WHOIS lookup

A WHOIS or domain lookup only tells you who registered the domain name - and since GDPR that is almost always a privacy service or a registrar, not a company. We look for the tells that identify the real business operating the site and match it to official trade registers.

A WHOIS / domain lookup shows

  • The domain registrar and name servers
  • Registration and expiry dates
  • A registrant that is usually redacted for privacy
  • No legal company, address or accountability

We show the company behind it

  • Registered legal name and trade name
  • Registration number (KVK, Companies House, HRB and more)
  • VAT number, registered address and status
  • Directors, employees, industry and group structure
