Practical uses

Bolster cybersecurity platforms

Bolster cybersecurity platforms
  • Protect your organization from domains that are associated with known cybercriminals. Integrate a domain history database into your security systems to find associations with malicious actors.
  • Include the examination of historical WHOIS records in your third-party risk assessment and monitoring strategies. Integrating WHOIS History Database into systems makes risk monitoring and management more robust and comprehensive.
  • Enrich cybersecurity platforms with historical domain ownership data. A domain history database can help protect clients from suspicious registrants, known threat actors, and trademark infringers. Even when their current WHOIS records have been redacted or privacy-protected, the database enables your platforms to flag domains that have historical ties to them.
  • Use WHOIS History to strengthen digital risk protection and contextualize IoCs—such as hostnames, IP addresses, and email addresses—found on deep web forums and pastebins and to execute enrichment and pivot queries.

Domains associated with threat actors are revealed, along with other WHOIS record details that shed light on ongoing investigations.
  • Create an attacker profile by digging up the domain ownership of a known threat actor. The past and present domain portfolios of cybercriminals can tell a story and reveal a penchant for specific domain name types. Recognizing a pattern among the domains you dig up from WHOIS History Database can help solve a specific cybercrime.
