Set it to restrict unused features. - **[PASS]** Content-Security-Policy is present - **[INFO]** Cross-Origin-Opener-Policy is set but not '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. - **[PASS]** X-Powered-By header is not present - **[PASS]** Server header is present without version info - **[PASS]** Domain is in the Chrome HSTS preload list (status: preloaded) ### Content Security Policy (A+ — 100/100) *9 of 10 CSP checks passed* - **[INFO]** Raw CSP policy - **[PASS]** default-src directive is set - **[PASS]** No 'unsafe-inline' in script source - **[PASS]** No 'unsafe-eval' in script source - **[PASS]** No wildcard in script source - **[PASS]** object-src is set to 'none' - **[PASS]** base-uri is properly restricted - **[PASS]** frame-ancestors directive is set - **[PASS]** form-action directive is set - **[PASS]** upgrade-insecure-requests is enabled ### TLS & Certificates (A+ — 100/100) *TLS 1.3, 7 checks passed* - **[PASS]** TLS 1.3 is used - **[PASS]** Strong cipher suite is used - **[INFO]** HTTP/2 is not negotiated — HTTP/2 provides multiplexing and header compression for better performance. - **[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 53 days) - **[PASS]** Certificate chain has 2 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 (B — 80/100) *Vulnerability disclosure policy* - **[PASS]** security.txt found - **[WARNING]** security.txt has expired — The Expires field is 2025-12-31T23:59:00.000Z, which is in the past. Update it. ### Cross-Origin Tab Safety (A+ — 100/100) *All 1 new-tab link(s) carry rel=noopener* - **[PASS]** All 1 new-tab link(s) carry rel=noopener ### CSP Inline-Style Readiness (D — 60/100) *171 inline style attribute(s) detected* - **[WARNING]** 171 inline style attribute(s) detected — Each `style=""` attribute forces `style-src 'unsafe-inline'` in any Content-Security-Policy, which negates most of CSP's XSS-mitigation value. 171 inline style(s) is high. Affected element types include: div, ul, svg, span, section. Move styles to a stylesheet; use CSS custom properties for runtime-dynamic values; or adopt a nonce/hash CSP policy. Most teams take the stylesheet path because it's also a maintainability win. ### Trusted Types (XSS Sink Hardening) (B — 95/100) *Trusted Types not enabled* - **[INFO]** Trusted Types not enabled — Trusted Types (CSP3) is a Chrome 83+ defense that requires DOM-XSS sinks (innerHTML, document.write, eval, ...) to receive a typed-and-sanitized value rather than a raw string. Adding `Content-Security-Policy: require-trusted-types-for 'script'; trusted-types default` neutralizes most DOM-XSS even when a payload reaches a sink. Adoption is currently ~0.1% of pages so this is informational; a roll-out usually starts in report-only mode. ### 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 (0/77 third-party resources)* - **[WARNING]** SRI adoption: 0/77 third-party resources protected (0%) — Of 77 third-party `
