how to quickly identify subdomain vulnerabilities before they become threats

the problem

managing subdomain security is a pain. endless enumeration, manual checks for misconfigurations, exposed files, outdated endpoints — it all takes time and effort. missing these issues can leave your assets exposed or open to attack.

the solution

introduce subdomain-vulnerability-scorer: an api that exhaustively enumerates subdomains using free dns and certificate transparency logs, then analyzes each for misconfigurations, exposed files, or outdated endpoints, providing a risk score for each subdomain.

GET /check?domain=example.com

// sample output shape
{
"subdomain": "api.example.com",
"risk_score": 7.2,
"issues": ["exposed admin panel", "outdated endpoint"],
"details": {
"exposed_files": ["config.php"],
"misconfigurations": ["ssl mismatch"]
}
}

how it works

this api performs exhaustive enumeration by querying free dns logs and certificate transparency logs. then, it analyzes each discovered subdomain for common misconfigurations, exposed files, and outdated endpoints using content inspection and fingerprinting, scoring each risk accordingly.
