Frequently Asked Questions

What is a website vulnerability scanner?
A website vulnerability scanner is a free online tool that automatically checks your website for common security weaknesses — outdated JavaScript libraries, exposed admin panels, directory listing, source map leaks, and sensitive file exposure. It shows findings ranked by severity with step-by-step fix instructions.
How do I scan my website for vulnerabilities?
Enter your website URL in the vulnerability scanner above. We'll fetch your page, analyze all scripts and resources, probe for exposed files and admin panels, and show you a prioritized report with specific remediation steps for each vulnerability found.
What vulnerabilities does this scanner detect?
We check for outdated JavaScript libraries with known CVEs, exposed admin panels (wp-admin, phpMyAdmin, etc.), directory listing enabled on your server, leaked source maps that expose source code, and publicly accessible sensitive files like .env or backup archives.
Is this vulnerability scanner safe to use on my website?
Yes. Our scanner is completely non-intrusive — it only makes standard HTTP requests that any browser would make. We never attempt to exploit vulnerabilities, only detect them. There's no risk to your site or users.
How often should I scan for vulnerabilities?
Scan after every deployment and at least weekly. New vulnerabilities in JavaScript libraries are disclosed regularly, and configuration changes can accidentally expose sensitive files. Continuous monitoring is available on paid plans.
What should I do if vulnerabilities are found?
Each finding includes specific remediation steps. Priority order: update vulnerable JavaScript libraries (they're most commonly exploited), remove or restrict access to admin panels, disable directory listing, delete source maps from production, and restrict sensitive files.
Is this website vulnerability scanner free?
Yes, our vulnerability scanner is completely free. It runs 7 content security checks and is part of SecScanner's free toolkit that also covers SSL, HTTP headers, DNS, cookies, and more — 60+ checks total.
