CertWatch

CertWatch searches the Certificate Transparency Logs for a domain to identify further sub domains.

CertWatch supports two different search methods:

  • Domain
    Search subdomains for the given domain, e.g. example.com. This will output results like www.example.com, sub1.example.com.
  • Domain without TLD
    Search for subdomains of the given domain, independent of the TLD, e.g. example. This will output results like www.example.com, www.example.net.
