A website security checker is a tool that analyzes your website's security configuration including SSL certificates, DNS records, HTTP security headers (like HSTS, CSP, X-Frame-Options), TLS protocols, and email security settings (SPF, DKIM, DMARC). It provides a comprehensive security score and actionable recommendations to improve your website's security posture.
SSL certificate analysis examines your website's SSL/TLS certificate chain, validates certificate expiration dates, checks certificate authority (CA) trust, analyzes signature algorithms, and verifies certificate configuration. Our tool performs certificate chain analysis, checks TLS protocol versions, cipher suites, and identifies potential vulnerabilities in your SSL configuration.
Asset discovery is the process of identifying all digital assets associated with your domain, including subdomains, IP addresses, cloud infrastructure, SSL certificates, and shadow IT assets. This helps organizations maintain a complete inventory of their digital footprint and identify potential security risks from unknown or unmanaged assets.
Yes, securelyze is completely free to use. All features including website security checking, SSL certificate analysis, DNS security checks, security header analysis, and asset discovery are available at no cost. No credit card or account registration is required.
Our security checker analyzes all major HTTP security headers including Strict-Transport-Security (HSTS), Content-Security-Policy (CSP), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, and more. It checks for proper configuration and provides recommendations for missing or misconfigured headers.
The security score (0-100) is calculated based on industry-standard security best practices. It evaluates SSL/TLS configuration, security headers implementation, DNS security settings, email security (SPF, DKIM, DMARC), and other security factors. The score reflects your website's overall security posture and helps identify areas for improvement.
Yes, you can check multiple domains. Simply enter each domain separately in the security checker tool. Each scan is independent and provides detailed analysis for that specific domain. You can also use the asset discovery tool to find all assets related to a domain.
The security report includes SSL certificate details, DNS records analysis, security headers status, TLS/SSL protocol information, email security configuration (SPF, DKIM, DMARC), CAA records, vulnerability assessment, and actionable recommendations. You can download the report as JSON for further analysis or sharing with your team.
