# BeaverCheck Audit Report — https://arrl.org **Date:** April 22, 2026 **URL:** https://arrl.org **Overall Grade:** D (67/100) **Report:** https://beavercheck.com/results/36095ca9-3c04-49de-8233-6fb04c43e485 ## Top Findings 1. **[CRITICAL]** Content-Security-Policy header is missing — Security > Security Headers 2. **[CRITICAL]** HSTS header is missing — Security > Security Headers 3. **[CRITICAL]** No Content-Security-Policy header found — Security > Content Security Policy 4. **[CRITICAL]** Page weighs 10.1 MB (5.6 MB transferred) — Performance > Page Weight Budget 5. **[CRITICAL]** 2 image-in-link without alt text — Accessibility > Alt Text Quality --- ## Lighthouse Scores | Category | Score | |----------|-------| | Performance | 25 | | Accessibility | 59 | | Best Practices | 92 | | SEO | 83 | --- ## Security ### Security Headers (F — 10/100) *2 of 10 headers properly configured* - **[CRITICAL]** HSTS header is missing — Strict-Transport-Security forces browsers to use HTTPS, preventing downgrade attacks. 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. - **[PASS]** X-Powered-By header is not present - **[PASS]** Server header is present without version info ### 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 1.2, 7 checks passed* - **[PASS]** TLS 1.2 is used - **[INFO]** TLS 1.3 is not negotiated — TLS 1.3 offers improved performance and security. Consider enabling it. - **[PASS]** Strong cipher suite is used - **[INFO]** HTTP/2 is not negotiated — HTTP/2 provides multiplexing and header compression for better performance. - **[PASS]** Certificate is valid (expires in 249 days) - **[PASS]** Certificate chain has 4 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 --- ## Advanced Security ### Subresource Integrity (F — 20/100) *0 of 11 external resources have SRI* - **[WARNING]** External script from www.googletagmanager.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code. - **[WARNING]** External script from www.googletagmanager.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code. - **[WARNING]** External script from pagead2.googlesyndication.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code. - **[WARNING]** External script from cdn.informz.net lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code. - **[WARNING]** External script from www.googletagmanager.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code. - **[WARNING]** External script from pagead2.googlesyndication.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code. - **[WARNING]** External script from ads.arrl.org lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code. - **[WARNING]** External script from ads.arrl.org lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code. - **[WARNING]** External script from ads.arrl.org lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code. - **[WARNING]** External script from ads.arrl.org lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code. - **[WARNING]** External script from www.googletagmanager.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code. ### JS Library Vulnerabilities (A+ — 100/100) *No known vulnerabilities* - **[PASS]** No known JavaScript library vulnerabilities detected ### Information Leakage (A+ — 100/100) *No exposures* - **[PASS]** security.txt is present — good practice - **[PASS]** No sensitive files exposed ### Email Security (A+ — 100/100) *DMARC: reject* - **[PASS]** DMARC policy is reject — strongest protection ### Permissions-Policy (D — 40/100) *No header set* - **[WARNING]** No Permissions-Policy header — Consider adding a Permissions-Policy header to restrict browser feature access from embedded content. ### CORS Configuration (B — 80/100) *No CORS headers* - **[PASS]** No CORS headers present — secure default --- ## Performance ### Page Weight Budget (F — 0/100) *5.6 MB transferred, 96 requests* - **[CRITICAL]** Page weighs 10.1 MB (5.6 MB transferred) - **[WARNING]** Images are 3.4 MB — compress or use modern formats — Convert images to WebP/AVIF and resize to display dimensions to reduce transfer size. - **[WARNING]** JavaScript is 1.8 MB — consider code splitting or lazy loading — Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts. - **[INFO]** CSS is 206 KB — consider purging unused styles — Remove unused CSS rules with tools like PurgeCSS to reduce stylesheet size. - **[INFO]** 96 HTTP requests - **[INFO]** Estimated 1.2 g CO2 per page load ### Third-Party Impact (D — 50/100) *100% third-party, 0 ms blocking* - **[WARNING]** Third-party code accounts for 100% of page weight (5.6 MiB of 5.6 MiB) -
