Zero Reputation Domain (ZRD) Block List

Research by Spamhaus has driven the development of the Zero Reputation Domain (ZRD) service. ZRD is designed to thwart cyber criminals who use newly registered domains to send spam and drive traffic to harmful websites. Cyber criminals use these new domains  hoping that users will fall victim before its reputation can be analyzed and blocked. 

Legitimate organizations will rarely activate a domain and start using it immediately after registration. As a preventative method, ZRD automatically adds newly-registered and previously dormant domains to a blocklist for 24 hours.  This protects users from unknown domains until they can establish a positive reputation without involvement in malicious activity. 

The ZRD feed blocks email traffic associated with newly registered domains to provide an extra layer of protection against malware, ransomware and spamming.
