# BeaverCheck Audit Report — https://www.vanguardmexico.com **Date:** November 6, 2026 **URL:** https://www.vanguardmexico.com **Overall Grade:** C (79/100) **Report:** https://beavercheck.com/results/2979dfe7-3f73-4513-a742-6bea493cc897 ## Top Findings 1. **[CRITICAL]** Content-Security-Policy header is missing — Security > Security Headers 2. **[CRITICAL]** Page weighs 19.7 MB (5.3 MB transferred) — Performance > Page Weight Budget 3. **[CRITICAL]** 1 control(s) without accessible label — Accessibility > Form Accessibility 4. **[CRITICAL]** 1 link(s) with no accessible text — Accessibility > Link & Button Quality 5. **[CRITICAL]** Soft 404: server returns HTTP 200 for non-existent pages — Accessibility > 404 Error Page --- ## Lighthouse Scores | Category | Score | |----------|-------| | Performance | 33 | | Accessibility | 83 | | Best Practices | 92 | | SEO | 92 | --- ## Security ### Security Headers (F — 20/100) *2 of 10 headers properly configured* - **[WARNING]** HSTS is enabled but max-age is short (15768000s, should be >= 31536000s) — The header is present and enforced, so first-visit protection is already in place; a short max-age just means the browser forgets it sooner. Set max-age to at least 31536000 (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. - **[PASS]** X-Powered-By header is not present - **[PASS]** Server header is not present - **[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 52 days) - **[PASS]** Certificate chain has 3 certificates - **[PASS]** Certificate uses modern signature algorithm - **[PASS]** Certificate covers 3 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) *Akamai* - **[PASS]** Akamai detected — Detected via: akamai-grn: 0.9dd73b17.1793979577.3ecdf3eb ### security.txt (B — 70/100) *Vulnerability disclosure policy* - **[PASS]** security.txt found - **[WARNING]** security.txt: Missing required 'Contact' field - **[WARNING]** security.txt: Missing required 'Expires' field (RFC 9116) ### Cross-Origin Tab Safety (C — 75/100) *3 of 3 new-tab link(s) missing rel=noopener* - **[WARNING]** 3 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 (C — 75/100) *17 inline style attribute(s) detected* - **[WARNING]** 17 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. 17 inline style(s) is moderate. Affected element types include: div, p, a. 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) (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 (0/7 third-party resources)* - **[WARNING]** SRI adoption: 0/7 third-party resources protected (0%) — Of 7 third-party `
