Why Use Security Testing Tools?

Web security is no longer optional - it's essential. Our free security tools help you identify vulnerabilities, validate SSL configurations, and ensure your HTTP security headers follow OWASP best practices. Whether you're preparing for a security audit, checking compliance requirements, or just want to protect your users, these tools provide instant insights into your website's security posture.

Security Audit

Verify all recommended security headers are present and properly configured. Get a comprehensive security grade from A+ to F based on OWASP guidelines.

Compliance Checking

Ensure your site meets security requirements for PCI DSS, HIPAA, SOC 2, and other compliance frameworks that mandate SSL and security headers.

Penetration Testing Prep

Identify potential security misconfigurations before an external audit. Fix issues proactively rather than waiting for penetration testers to find them.

DevSecOps Validation

Verify security headers after deployments. Integrate into your CI/CD pipeline using our API to catch security regressions early.

Frequently Asked Questions

What are HTTP security headers and why are they important?
HTTP security headers are response headers that instruct browsers to enable security features. Key headers include: Content-Security-Policy (CSP) prevents XSS attacks, Strict-Transport-Security (HSTS) enforces HTTPS, X-Frame-Options prevents clickjacking, X-Content-Type-Options prevents MIME sniffing. Missing security headers leave your site vulnerable to common attacks.
How do I check if my SSL certificate is valid?
Use bugX's SSL Checker to verify your certificate: 1) Enter your domain name, 2) The tool checks certificate validity, expiration date, issuer, and chain of trust, 3) Review the results for any warnings about expiring certificates or configuration issues. You should check SSL certificates regularly to avoid unexpected expiration.
What is CORS and how do I test it?
CORS (Cross-Origin Resource Sharing) is a browser security feature that controls which domains can access your API. Use the CORS Tester to: 1) Enter your API endpoint URL, 2) Specify the origin domain making the request, 3) Check if Access-Control-Allow-Origin and other CORS headers are properly configured. Misconfigured CORS can either block legitimate requests or expose your API to unauthorized access.
What security headers should every website have?
Essential security headers: 1) Content-Security-Policy - prevents XSS and injection attacks, 2) Strict-Transport-Security - enforces HTTPS connections, 3) X-Frame-Options - prevents clickjacking, 4) X-Content-Type-Options: nosniff - prevents MIME type sniffing, 5) Referrer-Policy - controls referrer information, 6) Permissions-Policy - restricts browser features. Our Security Headers Checker grades your site and shows which headers are missing.
How often should I audit my website's security?
Run security audits: 1) After any deployment or code change, 2) Monthly for SSL certificate expiration checks, 3) Quarterly for comprehensive security header reviews, 4) Immediately after security vulnerabilities are disclosed. Pro users can use our API to automate regular security checks and receive alerts for any issues.
