What tools monitor for impersonation domains?

DNSTwist is an open-source tool generating domain variations and checking registration status. It identifies: typos, homoglyphs, bit flips, and other manipulation techniques potentially targeting your domain.

Commercial services like PhishLabs, Bolster, and RiskIQ provide comprehensive monitoring: continuous scanning, alert management, and takedown assistance. They offer scale and response capabilities beyond DIY tools.

DMARC reports reveal domains already sending as your brand, whether legitimately authorized or spoofed. Analyzing aggregate reports identifies impersonation attempts that have already occurred.
