Benefits

  • If a newly registered or dropped (on-hold, deleted) domain name contains any of the search terms, then it will be returned in the search result.

  • By default, the result contains all the domain names registered or dropped within the last day. Your program can actively monitor each set of terms by automatically submitting a single query each day.

  • You can monitor for domain registration, expiration or ownership change. You have the option to exclude terms if they should not be a part of the search.

  • You can backtrack the alerts up to 14 days by setting sinceDate request parameter.

  • The Brand Alert API searches new .com, .net, .org, .biz, .mobi, .us, .pro, .coop, .asia and thousands of gTLDs and ccTLDs for your specified terms.

  • You can also use our "with typos" option, which adds automatically generated misspellings to your search terms to boost your anti-phishing activities.

Practical usage

Trademark Infringement and Copyright Violation Prevention

Track all domains that contain your company or brand name as part of brand protection and anti-counterfeiting efforts. Use them as Brand Alert search terms to get an exhaustive list of web properties that may be mimicking your organization.

Email Security Enhancement

Prevent all employees from interacting with the owners of spoofed email addresses. Brand Alert can alert you each time a well-known brand or company name gets used in newly registered domains (NRDs). Regular monitoring can help you reduce risks tied to phishing, business email compromise (BEC), invoice scams, and spam.

Keep Track of Domain Deletions

Be alerted as soon as domain names that contain branded strings are being dropped by their current registrant, as part of your defensive domain registration efforts or to support your business growth.
