how to quickly identify risky subdomains without manual scans

the problem

manually checking all subdomains for misconfigurations, outdated services, or exposed endpoints is time-consuming and error-prone. it often leads to missed vulnerabilities, especially in complex environments.

the solution

use the subdomain-vulnerability-ranker api to automate subdomain enumeration and vulnerability scoring. it searches dns records and certificate transparency logs to find subdomains, then evaluates their security posture.

here`s an example curl command:

bash
curl -X GET 'https://subdomain-vulnerability-ranker.apimesh.xyz/check?domain=example.com'

sample output:

{
"subdomain": "api.example.com",
"score": 85,
"issues": ["exposed admin panel", "outdated ssl"],
"details": {
"misconfigurations": true,
"exposedEndpoints": ["admin", "internal"],
"outdatedServices": ["v1 api"]
}
}

how it works

it performs deep enumeration through free dns, certificate transparency logs, and other sources to find all subdomains. then, it analyzes configurations, SSL status, and exposed endpoints to generate a risk score and identify potential issues.
