Domains owned by spammers and used for spam or other malicious purposes. Also domains owned by non-spammers, used for legitimate purposes, but abused by spammers. Both spam and legitimate list include basic spam, phishing, malware, botnet C&C and redirector domains.
Domain based block lists complement IP-reputation threat data which is based on a sender’s reputation. You get extra protection because even if a spammer has used a clean IP to send email, domain block listing identifies low reputation or malicious domains in the email message.
Cyber criminals use newly registered and active domains to send spam and drive traffic to harmful websites hoping that users will fall victim before a domain has been analyzed for its reputation. ZRD automatically adds newly-registered and previously dormant domains to a block list for 24 hours
Legitimate organizations will rarely activate a domain and start using it immediately after registration so ZRD protects you and your users from clicking on links and visiting domains until it can be firmly established that they are not associated with malicious activities.
