how to automate comprehensive subdomain vulnerability scans without manual effort

the problem

keeping track of all subdomains for a domain can be a pain. manual checks are slow, incomplete, and prone to missing critical misconfigurations or exposed endpoints. this leaves your assets vulnerable and increases security risks.

the solution

introduce the subdomain-vulnerability-enum api. it performs thorough subdomain enumeration by querying free dns records, certificate transparency logs, and public dns api sources. it then analyzes the results to identify misconfigurations, exposed sensitive files, or outdated endpoints.

example request:

curl -X GET "https://subdomain-vulnerability-enum.apimesh.xyz/check?domain=example.com"

# response shape
{
  "subdomains": ["dev.example.com", "admin.example.com"],
  "exposures": {
    "dev.example.com": ["exposed_config.php"],
    "admin.example.com": ["outdated_api/v1"]
  },
  "status": "completed"
}


## how it works
the api pulls data from multiple sources: free DNS records, certificate transparency logs, and public DNS APIs. it combines these inputs to discover all subdomains. then, it performs analysis to scan for common misconfigurations, exposed files, or outdated endpoints, presenting a comprehensive security overview.
