Why Scan Your Website Security?

Security headers and SSL/TLS configuration are your website's first line of defence against common attacks like cross-site scripting (XSS), clickjacking, and man-in-the-middle interception. Misconfigured or missing headers leave your site and users vulnerable.

This free security scanner checks your site's HTTP security headers (Content-Security-Policy, X-Frame-Options, Strict-Transport-Security, and more), validates your SSL certificate chain, analyses TLS protocol support, and audits cookie security flags. Results are graded to help you prioritise fixes. Run regular scans to maintain a strong security posture and protect your Australian business and customers.
