Domains Dataset

The Domains collection is composed of the Alexa top 1 million domains, fetched and resolved daily and then scanned. When scanning, we collect relevant security information about the Domain Name System (DNS) configuration of the domain, Simple Mail Transfer Protocol (SMTP) (and any StartTLS certificates), and websites (both HTTP and HTTPS).
