Why Monitoring Similar Domains is so Important

DNSTwister Application Screenshot

Domain impersonation is a real problem.

Typosquatting, phishing, and IP infringement are serious threats to businesses of all sizes. Attackers register domains with small spelling changes, like swapping letters or adding extra characters, to trick users into visiting malicious sites or responding to emails they believe are from someone they know.



Protective Shield

How we solve it

By monitoring changes in the public Domain Name System (DNS), DNSTwister helps you stay ahead of threats by detecting newly registered look-alike domains, and monitoring DNS changes on these domains, alerting you in real time. By proactively monitoring for suspicious activity such as registering an MX record which would allow them to send email from that domain, you can protect your customers and reputation.
