What Is DomainTools?
DomainTools provides domain, WHOIS and DNS intelligence, positioned today mainly for threat intelligence and domain security teams.
Best for: Security and research teams investigating domains and their ownership history.
Iris Investigate interprets an entered domain or IP address and then allows analysts to pivot through related infrastructure. Investigations can hold tags and notes shared among colleagues, keeping a case's evidence separate from ad hoc lookups. DomainTools also distinguishes limited personal research access from enterprise investigation features, including broader datasets and security-platform integrations.
