What Is SecurityTrails?
SecurityTrails provides current and historical DNS and WHOIS data through its API and search tools, aimed at security teams.
Best for: Researchers needing historical DNS and WHOIS records.
SecurityTrails is oriented toward querying observed domain and infrastructure records instead of managing ownership of those names. A security team may use historical DNS associations to identify related hosts even after a live record changes. Data availability and API access depend on the subscribed service, so it should not be treated as a complete history of every registration or DNS event.
