Know what can impersonate your domain
before attackers do
A plain-English first check for lookalikes, typos, and login-style domains that could put customers at risk.
Threat Snapshot
Find Impersonations
Guardian finds registered domains that closely resemble yours, including typos and brand-plus-word variants.
It then investigates these websites for signs of impersonation. Monitor findings, automate follow-up, and initiate formal takedown requests before threats reach your staff or customers.
