Is B2B lookup compliant with data protection?

Yes, B2B lookup is compliant with data protection law. Identifying individual visitors to websites is highly questionable in terms of data protection law, but this does not usually apply to access by companies. This is because the applicability of the General Data Protection Regulation (GDPR) is limited to natural persons. In order to exclude the possibility of indirectly drawing conclusions about a natural person behind the website – e.g. in the case of very small companies – only accesses by companies that have visited the website on the basis of their abbreviated IP address are listed.
