Frequently Asked Questions

What is typosquatting?

Typosquatting is when someone registers domains that are misspellings or visual lookalikes of popular brands. These are often used for phishing, ad fraud, or brand impersonation attacks.

What types of typo variations do you detect?

We detect: character omission (gogle), addition (googgle), substitution (goggle), transposition (googel), adjacent key errors (foogle), homoglyphs (googIe with capital I), and bitflip domains.

How are risk levels determined?

Critical: homoglyphs and highly deceptive typos. High: common misspellings likely to catch users. Medium: less common errors. Low: unlikely typos but still worth monitoring.

Can I use this for brand monitoring?

Absolutely! Run regular typosquatting scans to detect new registrations that might be targeting your brand. Take action on critical and high-risk domains.
