Frequently Asked Questions
What is a domain monitoring service?
A domain monitoring service continuously watches the internet for domains that could be used to target an organization, its brand, employees, or customers. Effective monitoring goes beyond finding similar domain names, using infrastructure and threat signals to identify phishing, impersonation, fraud, and other malicious activity.
How does Netcraft monitor domains?
Netcraft combines domain and infrastructure monitoring with signals from registrations, DNS, hosting, certificates, technical configurations, and known criminal infrastructure. These signals are correlated with threat intelligence and patterns from previous attacks to distinguish genuine threats from benign registrations.
What types of domains does Netcraft detect?
Netcraft identifies domains associated with phishing, brand impersonation, typosquatting, homoglyph abuse, and other forms of malicious domain activity. This includes lookalike domains designed to resemble legitimate brands, as well as domains connected to known phishing infrastructure and campaigns.
Can Netcraft detect newly registered phishing domains?
Yes. Netcraft monitors newly registered domains alongside DNS changes, certificate issuance, hosting activity, and other infrastructure signals that can indicate a developing phishing campaign. This can allow malicious infrastructure to be identified before phishing content is deployed.
What happens after a malicious domain is detected?
Once a threat is identified, Netcraft validates the evidence and can move from detection to disruption, including blocking and takedown activity with hosting providers and registrars. Netcraft also continues monitoring takedowns for reappearance and can restart the process if malicious content returns or moves to another host.
How is Netcraft different from domain monitoring tools?
Netcraft goes beyond producing a list of suspicious domain registrations. It connects domain monitoring with threat intelligence, automated validation, infrastructure analysis, blocking, and takedown, allowing organizations to move from finding a potential threat to disrupting it through the same platform. Netcraft can also identify sufficient evidence to support disruption before malicious content is live, rather than relying solely on monitoring an active website.
