What is a Vulnerability Scanner?

A vulnerability scanner is a security tool that automatically scans websites and web applications for known security weaknesses. It checks for common vulnerabilities like SQL injection, cross-site scripting (XSS), missing security headers, outdated software, and misconfigurations that could be exploited by attackers.

How to Use

1. Enter the full URL of the website you want to scan 2. Click 'Start Scan' to begin the security analysis 3. Review the results and prioritize fixing critical and high-severity issues

Understanding Severity Levels

• Critical: Immediate action required - can lead to full system compromise • High: Should be fixed urgently - significant security risk • Medium: Should be addressed soon - moderate security impact • Low: Minor issues - fix when convenient

Frequently Asked Questions

Is it legal to scan websites for vulnerabilities?

You should only scan websites that you own or have explicit permission to test. Unauthorized security scanning may be illegal and could be considered a cyber attack. Always get written authorization before testing any website you don't own.

What types of vulnerabilities does this scanner check for?

This scanner checks for common web vulnerabilities including: SQL injection, Cross-Site Scripting (XSS), missing security headers (HSTS, CSP, X-Frame-Options), outdated software versions, weak TLS configurations, insecure cookies, and information disclosure issues.

Why is my security score low even though my site seems to work fine?

A website can function perfectly while still having security vulnerabilities. Security issues often don't affect normal functionality but can be exploited by attackers. Common issues include missing security headers, outdated libraries, or configuration weaknesses that aren't visible to regular users.

How often should I scan my website?

Regular scanning is recommended: after any code deployment, at least monthly for active sites, after adding new features or third-party integrations, and whenever new vulnerabilities are publicly disclosed that might affect your technology stack.

What should I do after finding vulnerabilities?

Prioritize fixes by severity: Critical issues need immediate attention. Create a remediation plan, fix issues in a test environment first, then deploy fixes to production. Re-scan after fixes to verify they're resolved. Consider engaging security professionals for critical vulnerabilities.
