Website Security & Vulnerability Audit

smart-digital/website-security-vulnerability-audit

Automated security and vulnerability audit for websites. Detects WordPress plugin vulnerabilities, checks for updates, analyzes SSL/TLS, security headers, and CMS security

Audit HTTP response headers (CSP, HSTS, X-Frame-Options) to verify web application security and compliance standards.

Check common HTTP security headers for one or more URLs (Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP/COEP/CORP). Useful for quick security hardening audits.

Http Header Inspector

zerobreak/http-header-inspector

HTTP header inspector that pulls response headers from any URL, scores them for security gaps, and flags missing CSP, HSTS, and X-Frame-Options, so teams can audit caching, redirects, and server config without running curl.

Check CORS response headers (Access-Control-Allow-Origin, -Credentials, -Methods, -Headers, -Expose-Headers, -Max-Age, Vary: Origin) for one or more URLs. Optionally performs a preflight OPTIONS check. Useful for debugging browser/API integrations and spotting risky CORS misconfigurations.

Fetches URLs and validates the Strict-Transport-Security (HSTS) response header. Parses directives (max-age/includeSubDomains/preload), flags missing/invalid configuration, and checks common best practices. Outputs per-URL results plus SUMMARY and REPORT.

Website Health Report

automation-lab/website-health-report

Comprehensive website health audit in a single run. Checks HTTP status, SSL certificate, DNS resolution, security headers, meta tags, response time, and robots.txt. Returns a unified health score (0-100) with per-category grades.

Fetch URLs and analyze Set-Cookie response headers for security attributes: Secure, HttpOnly, SameSite, plus __Host- / __Secure- prefix rules. Produces per-cookie results with warnings/errors and writes SUMMARY + REPORT for quick auditing.
