CorelightvsDomainTools Iris

Corelight is an Open Network Detection and Response (NDR) platform created by the original developers of Zeek (formerly Bro). Corelight sensors passively monitor physical and cloud network traffic, transforming raw, high-volume network packets into compact, highly structured security logs that accelerate incident response investigations by up to 20x. By parsing over 400 network protocol attributes without capturing cumbersome PCAP payloads, Corelight drastically reduces SIEM ingestion and storage costs. It includes embedded Suricata signature scanning, encrypted traffic analysis for C2 beacons and unauthorized SSH channels, and Smart PCAP technology for selective packet retrieval.

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.
