Tool guidance
How to use this tool
The comparison runs in your browser and does not store the domains.
How to use it
Enter the trusted brand or domain.
Enter the suspicious URL or domain.
Compare the base domains, subdomains, wording, and similarity signals.
Read the output as a similarity check, not a verdict.
What results mean
Similarity is not proof of phishing.
Subdomains can make a URL look familiar while the base domain is different.
Punycode, hyphens, numbers, and login-style words deserve closer review.
What to do next
Request brand monitoring for repeated reports.
Use Manual Report when customers or payments are involved.
Report suspicious links for manual review.
This is a similarity check, not proof of phishing. It does not replace brand monitoring or manual review.

FAQ

A domain designed to resemble a trusted brand, product, or official website.
Does similarity prove phishing?

Subdomains can make a URL look familiar while the base domain belongs to someone else.
What should businesses do?
