DomainTools IrisvsZscaler Internet Access

DomainTools Iris (Iris Investigate and Iris Detect) is an elite cyber threat investigation and DNS intelligence platform used by Fortune 500 security teams, government agencies, and threat hunters worldwide. It provides deep visibility into the infrastructure behind malicious domains, phishing campaigns, and adversary networks. Leveraging decades of historical WHOIS records, passive DNS (pDNS), and SSL/TLS certificate associations, Iris allows defenders to pivot on shared technical fingerprints (such as registrant emails, nameservers, and IP subnets) to map out full adversary infrastructure before attacks strike corporate perimeters. Its predictive Domain Risk Score accurately identifies weaponized domains ahead of public blocklists.
