About This Tool

Data Sources: Certificate Transparency logs (crt.sh), Shodan (exposed services and CVEs), HTTP header analysis, and SSL certificate inspection.
Important: This tool is for authorized security assessments only. Do not scan domains without proper authorization. Results are cached for 24 hours.
