Lookalike domain monitoring to spot brand impersonation



What is lookalike domain monitoring?
Lookalike domain monitoring checks typos and visually similar versions of your domain for signs of potential brand impersonation. Attackers can use these domains for fake invoices, login pages, or fraudulent email.
Your DMARC policy cannot protect a domain you do not own. Lookalike monitoring complements DMARC monitoring by helping you investigate similar-looking domains outside your control.
- Find common typos and visually similar characters
- Review DNS, email, website, and blocklist signals together
- Prioritize investigation with low, medium, and high risk ratings
- Inspect the evidence before reporting suspected abuse
Go from similar names to meaningful signals
