What it looks for
Registered lookalikes that have mail servers are flagged as higher risk, because they can send email.
Every tool runs the same free check, which reads your MX, SPF, DKIM, DMARC, MTA-STS, website certificate, HTTPS, registration, DNSSEC and lookalike domains in one go.
- Typos and missing or doubled letters
- Swapped or substituted characters that look alike
- Different endings, such as .co instead of .com
- Added words and hyphens
Watch for new ones
Monitored domains are rechecked every week, and new lookalikes show up as findings, so you can warn customers and finance before a fake invoice lands.
