Practical Uses

  • It’s ideal for monitoring specific domain registrants in order to be alerted whenever their information appears in a newly-registered domain name.
  • Keep a close eye on known or suspected malicious organizations or individuals via the domains they register or drop, including malicious or brand-infringing domains operated by serial violators.
  • Observe registration activities connected to a physical location or a phone number, which can help track registrants who supply various names or contact information.
  • Monitor your competition for new online holdings, or changes to existing ones, before they are publicly announced.
  • Enhance email security by identifying phishing / spam emails / domains. Prevent email spoofing to protect both your customers' personal information and their loyalty to your brand.
