Add the header with a max-age of at least 1 year. - **[WARNING]** X-Content-Type-Options header is missing — This header prevents MIME-type sniffing, which can lead to XSS attacks. Set it to 'nosniff'. - **[WARNING]** X-Frame-Options header is missing — This header prevents clickjacking by controlling who can embed your page in a frame. Set it to DENY or SAMEORIGIN. - **[WARNING]** Referrer-Policy header is missing — Controls how much referrer information is sent with requests. Set to 'strict-origin-when-cross-origin' or stricter. - **[WARNING]** Permissions-Policy header is missing — Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features. - **[CRITICAL]** Content-Security-Policy header is missing — CSP is the most important header for preventing XSS attacks. See the CSP section for detailed analysis. - **[WARNING]** Cross-Origin-Opener-Policy header is missing — COOP isolates your browsing context, preventing cross-origin side-channel attacks. Set to 'same-origin'. - **[WARNING]** Cross-Origin-Embedder-Policy header is missing — COEP prevents loading cross-origin resources without explicit permission. Required for SharedArrayBuffer and high-resolution timers. - **[WARNING]** X-Powered-By header reveals technology stack — This header discloses server technology (e.g. Express, PHP), helping attackers target known vulnerabilities. Remove it. - **[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 45 days) - **[PASS]** Certificate chain has 3 certificates - **[PASS]** Certificate uses modern signature algorithm - **[PASS]** Certificate covers 2 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 (B — 75/100) *No WAF detected via response headers* - **[INFO]** No WAF detected — Response headers don't match any known WAF or bot-management product. Sites exposed to abuse (login, signup, payment) typically benefit from a WAF such as Cloudflare, Akamai, AWS WAF, or Imperva. ### security.txt (A+ — 100/100) *Vulnerability disclosure policy* - **[PASS]** security.txt found ### Cross-Origin Tab Safety (A+ — 100/100) *All 30 new-tab link(s) carry rel=noopener* - **[PASS]** All 30 new-tab link(s) carry rel=noopener ### 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 (F — 30/100) *0% SRI adoption (0/11 third-party resources)* - **[WARNING]** SRI adoption: 0/11 third-party resources protected (0%) — Of 11 third-party `
