What it does

Inspect public website HTTPS and security posture without intrusive scanning.

Website Security Analyzer reviews only publicly accessible responses from a supplied public HTTP or HTTPS URL. It follows a small, validated redirect chain, checks HTTPS availability and HTTP-to-HTTPS behavior, inspects certificate metadata, evaluates security headers and cookie attributes, identifies insecure resources in returned HTML, summarizes CORS and software-disclosure headers, checks /.well-known/security.txt, and produces an explainable score with severity-grouped recommendations. It never exploits vulnerabilities, authenticates to the target, brute-forces paths, or scans private networks.

HTTPS & Redirects

Checks HTTPS availability and whether the equivalent HTTP URL redirects to HTTPS.

TLS Certificate

Reports trust, hostname matching, issuer, subject, expiration, remaining days, and negotiated TLS version.

Browser Controls

Evaluates security-related response headers and cookie Secure, HttpOnly, and SameSite attributes.

Content Safety

Detects mixed-content references and insecure HTTP resources without requesting those resources.

Exposure & CORS

Summarizes software-disclosure headers and potentially permissive cross-origin policy signals.

Score & Guidance

Groups findings by severity and attaches a practical recommendation to every detected issue.
