What is a Website Security Scanner?

A website security scanner automatically checks your web applications and infrastructure for known vulnerabilities, misconfigurations, and security weaknesses. VulnScan combines 50+ open-source and proprietary scanning engines to provide the most comprehensive security assessment available.

Our scanner checks for the OWASP Top 10 vulnerabilities including SQL injection, cross-site scripting (XSS), broken authentication, server-side request forgery (SSRF), and more. We also track over 200 CVEs with public exploit code, meaning we can detect if your systems are vulnerable to actively exploited threats.

How Our Free Security Scan Works

Enter your domain in the scanner above, and within 60 seconds, our engines will enumerate all subdomains associated with your domain and identify which hosts are actively responding. This gives you an instant view of your external attack surface — the same view an attacker would have.

The full Deep Scan goes further: testing every discovered host for thousands of known vulnerabilities, checking for exposed secrets and API keys, analyzing SSL/TLS configurations, and generating a professional PDF report with step-by-step remediation guidance.

Stop wondering if you're vulnerable.
Know for certain.
