How to check for lookalike domains
Enter your domain and press Check. The scan checks variations of its organizational domain and returns all results sorted from high to medium to low risk, with unassessed and unregistered variations last. Use the column-header filters to narrow results by domain, risk, email configuration, website availability or blocklist status. Open View data for the DNS and network details.
What to do with suspicious lookalike domains
Review the domain name, website content and email configuration together. If you confirm impersonation, report it to the relevant registrar, hosting provider or abuse service.

Lookalike domain checker FAQs
A lookalike domain resembles another domain through spelling changes, swapped characters or similar-looking characters. Some are legitimate independent domains; others may be used to impersonate a brand.
No. Public risk ratings use email configuration and blocklist signals to help prioritize review. The checker does not assess domain-name suspicion or classify website content. Confirm the evidence before reporting a domain.
No. The tool runs the checks directly and returns the results without saving them to the database or enabling ongoing monitoring.
No. It checks generated variations, not every domain on the internet. Registration is inferred from published nameservers, and email records indicate configuration rather than observed email traffic.
