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.

Filter

Filters the results to include only entries where the string before the base domain matches the specified text.

Result

Domain Valid until Transparency Log 3 of 4 (100)
