Add the header with a max-age of at least 1 year. - **[PASS]** X-Content-Type-Options is properly configured - **[PASS]** X-Frame-Options is properly configured - **[PASS]** Referrer-Policy is properly configured - **[PASS]** Permissions-Policy is set - **[CRITICAL]** Content-Security-Policy header is missing — CSP is the most important header for preventing XSS attacks. See the CSP section for detailed analysis. - **[PASS]** Cross-Origin-Opener-Policy is properly configured - **[PASS]** Cross-Origin-Embedder-Policy is set - **[PASS]** X-Powered-By header is not present - **[PASS]** Server header is present without version info - **[INFO]** Domain is not in the Chrome HSTS preload list (status: unknown) — Submit your domain to hstspreload.org to close the trust-on-first-use gap. Requires a preload-ready HSTS header (max-age=31536000+, includeSubDomains, preload). ### Content Security Policy (F — 0/100) *No enforcing CSP policy found* - **[CRITICAL]** No Content-Security-Policy header found — CSP is the most effective defense against XSS attacks. Add a Content-Security-Policy header to restrict resource loading. ### TLS & Certificates (A+ — 100/100) *TLS 1.3, 8 checks passed* - **[PASS]** TLS 1.3 is used - **[PASS]** Strong cipher suite is used - **[PASS]** HTTP/2 is negotiated - **[INFO]** OCSP stapling not enabled — Without stapling, the browser performs a separate OCSP roundtrip on first connection -- adding latency and leaking the visited host to the CA. Enable OCSP stapling on your TLS server. - **[PASS]** Certificate is valid (expires in 63 days) - **[PASS]** Certificate chain has 4 certificates - **[PASS]** Certificate uses modern signature algorithm - **[PASS]** Certificate covers 1 domain(s) - **[PASS]** Certificate is issued by a trusted CA ### Cookie Security (A+ — 100/100) *No cookies set — no cookie security risks* - **[PASS]** No cookies set — no cookie security risks ### Cookie Hygiene (A+ — 100/100) *No cookies set -- cookie-hygiene check is N/A* - **[PASS]** No cookies set ### WAF / Bot Protection (A — 90/100) *Cloudflare WAF (active mitigation)* - **[PASS]** Cloudflare WAF (active mitigation) detected — Detected via: cf-ray: a4eb4a244f112a1d-CDG; cf-mitigated: challenge ### security.txt (C — 60/100) *No security.txt file found* - **[INFO]** No security.txt file found — security.txt (RFC 9116) provides a standardized way for security researchers to report vulnerabilities. Create one at /.well-known/security.txt with at least a Contact field. ### Cross-Origin Tab Safety (C — 75/100) *1 of 7 new-tab link(s) missing rel=noopener* - **[WARNING]** 1 link(s) open in a new tab without rel=noopener — Without rel="noopener", the destination tab can navigate the original tab via window.opener -- a reverse-tabnabbing phishing primitive. Modern browsers default to noopener since Chrome 88 / Firefox 79 / Safari 12.1, but explicit rel="noopener noreferrer" remains the documented best practice for older browsers, in-app webviews, and security scanners. ### CSP Inline-Style Readiness (A+ — 100/100) *No inline style attributes -- strict CSP is feasible* - **[PASS]** No inline style attributes detected ### Trusted Types (XSS Sink Hardening) (A+ — 100/100) *No CSP header -- Trusted Types check is N/A* - **[PASS]** No CSP header found -- Trusted Types check is N/A ### Bot Challenge Detection (A+ — 100/100) *Scan reached real page content (no bot-protection interstitial)* - **[PASS]** No bot-protection interstitial detected -- the rest of the report reflects the real page ### Soft-404 Detection (A+ — 100/100) *HTTP status is non-2xx -- soft-404 check is N/A* - **[PASS]** HTTP status is non-2xx -- soft-404 check is N/A ### Empty Page Detection (A+ — 100/100) *Page has substantive body text and no placeholder / template-leak signals* - **[PASS]** Page has substantive body text and no placeholder / template-leak signals ### Geo-Restriction Detection (A+ — 100/100) *No geo-restriction signals detected -- scan reached the page from an allowed region* - **[PASS]** No geo-restriction detected ### Maintenance Mode Detection (A+ — 100/100) *No maintenance-mode signals detected -- scan reached a normal page* - **[PASS]** No maintenance-mode signals detected ### Subresource Integrity Adoption (D — 50/100) *2% SRI adoption (1/46 third-party resources)* - **[WARNING]** SRI adoption: 1/46 third-party resources protected (2%) — Of 46 third-party `
