# BeaverCheck Audit Report — https://reddit.com **Date:** May 10, 2026 **URL:** https://reddit.com **Overall Grade:** C (76/100) **Report:** https://beavercheck.com/results/a026b2ce-fca6-49b5-ac34-b55733b69331 ## Top Findings 1. **[CRITICAL]** Content-Security-Policy header is missing — Security > Security Headers 2. **[CRITICAL]** No Content-Security-Policy header found — Security > Content Security Policy 3. **[CRITICAL]** Page body has only 144 chars of text -- likely empty / placeholder — Security > Empty Page Detection 4. **[CRITICAL]** Page weighs 11.7 MB (6.9 MB transferred) — Performance > Page Weight Budget 5. **[CRITICAL]** 1 image(s) missing alt attribute — Accessibility > Alt Text Quality --- ## Lighthouse Scores | Category | Score | |----------|-------| | Performance | 36 | | Accessibility | 79 | | Best Practices | 92 | | SEO | 69 | --- ## Security ### Security Headers (D — 50/100) *5 of 10 headers properly configured* - **[PASS]** Strict-Transport-Security is properly configured - **[PASS]** X-Content-Type-Options is properly configured - **[PASS]** X-Frame-Options is properly configured - **[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 - **[PASS]** Domain is in the Chrome HSTS preload list (status: preloaded) ### 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 - **[INFO]** HTTP/2 is not negotiated — HTTP/2 provides multiplexing and header compression for better performance. - **[PASS]** OCSP stapling enabled - **[PASS]** Certificate is valid (expires in 147 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 (A+ — 100/100) *Vulnerability disclosure policy* - **[PASS]** security.txt found - **[PASS]** security.txt is PGP signed ### Cross-Origin Tab Safety (A+ — 100/100) *No new-tab links found -- no tabnabbing surface* - **[PASS]** No new-tab links present ### 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 (F — 0/100) *1 empty-page signal(s) detected -- page may be a placeholder or have content-rendering bugs* - **[CRITICAL]** Page body has only 144 chars of text -- likely empty / placeholder — After HTML stripping, the page body contains 144 characters of text content. Below 200 chars almost always means: (1) the page is a placeholder that was never filled in, (2) JavaScript was supposed to render content but failed, (3) the page is a redirect / interstitial / wrapper that should have a real status code other than 200, or (4) it's a legitimately small page like a single-form login (in which case this finding is a false positive that confirms 'minimal content' is intentional). Review the page in a browser. If content is missing, the most common root cause is a JS-rendering pipeline that needs prerendering or server-side rendering for crawlers / scanners to capture content. ### 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 (A+ — 100/100) *Page has no third-party scripts or stylesheets -- SRI not applicable* - **[PASS]** No third-party scripts or stylesheets to protect with SRI ### CORS Depth (A+ — 100/100) *No CORS response headers -- the resource is same-origin-only by browser default* - **[PASS]** No CORS response headers -- the resource is same-origin-only by browser default ### Permissions-Policy Granularity (C — 60/100) *No Permissions-Policy header set -- powerful features (camera / microphone / geolocation / payment / USB) default to allow-on-same-origin* - **[WARNING]** Permissions-Policy header not set -- features default to allow-on-same-origin — Without a `Permissions-Policy` (or legacy `Feature-Policy`) header, every powerful browser feature defaults to its spec default policy (typically `self`). A third-party iframe injected via XSS or a misconfigured embed can still request access to the user's camera, microphone, geolocation, payment APIs, USB devices, etc. Explicitly deny features the page doesn't need: ``` Permissions-Policy: camera=(), microphone=(), geolocation=(), payment=(), usb=(), accelerometer=(), gyroscope=() ``` Features the page legitimately uses can stay enabled with `feature=(self)`. ### Referrer-Policy Strictness (B — 75/100) *Referrer-Policy header not set -- browser default applies (modern: strict-origin-when-cross-origin; legacy browsers: no-referrer-when-downgrade)* - **[INFO]** Referrer-Policy header not set -- browser default applies — Without an explicit `Referrer-Policy` header, the browser falls back to its default policy. Modern browsers (Chrome 85+, Firefox 87+, Safari 15+) default to `strict-origin-when-cross-origin`, which is privacy-safe. Legacy browsers default to the leaky `no-referrer-when-downgrade`, which sends the full URL (including path + query) on cross-origin HTTPS-to-HTTPS requests. Set an explicit header to ensure consistent behavior: ``` Referrer-Policy: strict-origin-when-cross-origin ``` This matches the modern browser default and is privacy-safe without breaking referrer-based same-origin analytics. ### Source Map Exposure (A+ — 100/100) *Source-map probe didn't run on this scan* - **[PASS]** Source-map probe didn't run on this scan ### HTML Version Disclosure (A+ — 100/100) *No software-version disclosures in HTML* - **[PASS]** No software-version disclosures in HTML ### Open Redirect Surface (A+ — 100/100) *No redirect-shaped query parameters in DOM links* - **[PASS]** No redirect-shaped query parameters in DOM links ### Auth Security (A+ — 100/100) *Page is not a login form -- auth-security checks are N/A* - **[PASS]** Page does not appear to be a login form ### Subdomain Inventory Exposure (A+ — 100/100) *No risky subdomain names in certificate SANs* - **[PASS]** No risky subdomain names in certificate SANs --- ## Advanced Security ### Subresource Integrity (A+ — 100/100) *No external resources* - **[PASS]** No external resources to protect ### 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 — 90/100) *DMARC: reject, SPF: ~all, DKIM, BIMI* - **[PASS]** DMARC policy is reject — strongest protection - **[INFO]** SPF ends in ~all (soft fail) — Soft fail tells receivers to accept-but-mark unauthorized mail. Migrate to -all once you've confirmed all legitimate senders are listed (DMARC aggregate reports help verify). - **[PASS]** DKIM configured (selectors: k1, google) - **[INFO]** MTA-STS not configured — MTA-STS forces inbound mail to use TLS, preventing downgrade attacks. Requires both a TXT record at _mta-sts. and a policy file at https://mta-sts./.well-known/mta-sts.txt. - **[INFO]** TLS-RPT not configured — TLS-RPT (RFC 8460) lets MTAs report TLS-handshake failures, so you can detect and fix MTA-STS misconfigurations. Add a TXT record at _smtp._tls.. - **[PASS]** BIMI configured and DMARC enforced — logo will display ### API Surface (A+ — 100/100) *No API specs or GraphQL introspection found (probed 11 candidate path(s))* - **[PASS]** No API specs or GraphQL introspection found (probed 11 path(s)) ### 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) *6.9 MB transferred, 120 requests* - **[CRITICAL]** Page weighs 11.7 MB (6.9 MB transferred) - **[WARNING]** JavaScript is 1.6 MB — consider code splitting or lazy loading — Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts. - **[WARNING]** 120 HTTP requests — consider bundling or reducing — Each request adds latency. Bundle small files, use sprites, or eliminate unnecessary requests. - **[INFO]** Estimated 1.4 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 (6.9 MiB of 6.9 MiB) - **[PASS]** Third-party blocking time is low (0 ms) ### Text Compression (A+ — 100/100) *All text resources are compressed* - **[PASS]** All text resources are compressed ### Image Optimization (B — 75/100) *55 images, 0 KB saveable* - **[PASS]** All images are well-optimized ### JS Execution Cost (F — 20/100) *16381ms total JS execution* - **[WARNING]** https://www.reddit.com/?solution=0bba8304a76a3ced0...: 4384ms CPU time - **[WARNING]** https://www.redditstatic.com/shreddit/sentry-DswLf...: 2963ms CPU time - **[WARNING]** https://www.redditstatic.com/shreddit/en-US/DRsNWZ...: 2890ms CPU time - **[WARNING]** https://www.redditstatic.com/js/concat?prefix=en-U...: 2372ms CPU time - **[WARNING]** Unattributable: 2096ms CPU time - **[WARNING]** Third-party scripts: 16381ms (100% of total) ### Font Loading (A+ — 100/100) *1 fonts (34 KB)* - **[INFO]** 1 font(s) use font-display: swap (FOUT risk but functional) ### JS Bundles (F — 20/100) *21 scripts, 925 KB unused* - **[WARNING]** https://www.gstatic.com/recaptcha/releases/U5VsmTD...: 161 KB unused (44%) — Consider code splitting or tree shaking to reduce unused code. - **[WARNING]** https://www.gstatic.com/recaptcha/releases/U5VsmTD...: 161 KB unused (44%) — Consider code splitting or tree shaking to reduce unused code. - **[WARNING]** https://www.gstatic.com/recaptcha/releases/U5VsmTD...: 161 KB unused (44%) — Consider code splitting or tree shaking to reduce unused code. - **[WARNING]** https://www.redditstatic.com/js/concat?prefix=en-U...: 153 KB unused (49%) — Consider code splitting or tree shaking to reduce unused code. - **[WARNING]** https://www.redditstatic.com/js/concat?prefix=en-U...: 121 KB unused (86%) — Consider code splitting or tree shaking to reduce unused code. - **[INFO]** Total unused JavaScript: 925 KB ### Resource Caching (A+ — 100/100) *All resources properly cached* - **[PASS]** No caching issues found ### Critical Rendering Path (A+ — 100/100) *No render-blocking resources* - **[PASS]** No render-blocking resources detected ### Resource Hints (A+ — 100/100) *No optimization needed* - **[PASS]** No resource hint issues ### HTTP/3 (QUIC) (B — 75/100) *HTTP/3 not advertised* - **[INFO]** HTTP/3 (QUIC) is not advertised — HTTP/3 isn't advertised via Alt-Svc and the worker didn't negotiate h3. HTTP/3 reduces handshake latency (1-RTT instead of 2-3 RTTs) and is more resilient on lossy connections. Most modern CDNs (Cloudflare, Fastly, AWS CloudFront, Google Cloud CDN) support HTTP/3 with a single config switch -- consider enabling for mobile-heavy workloads. ### Compression Algorithm (C — 70/100) *Main response served uncompressed* - **[INFO]** Main HTML response has no Content-Encoding (uncompressed) — The main HTML document is served without compression. The Text Compression section above lists the broader picture; for the main response specifically, even gzip would shave ~70-80% off most text payloads. ### LCP Image Preload (A+ — 100/100) *LCP preload audit not available* - **[PASS]** LCP image preload audit not available for this scan ### Main HTML Cache-Control (B — 90/100) *Main HTML max-age=3600 (~60min)* - **[INFO]** Main HTML cached for 60 minutes -- mild staleness risk ### Server-Timing Observability (A+ — 100/100) *3 Server-Timing entries advertised* - **[PASS]** Server-Timing header advertises 3 timing entries ### Server Response Intelligence (A+ — 95/100) *1 server-response signal(s) detected* - **[INFO]** No `ETag` or `Last-Modified` -- conditional GET not supported — Without either header, browsers can't issue conditional GETs and refresh always re-downloads the full response body even when nothing changed. Add `ETag: ""` (or `Last-Modified: `) on cacheable responses; the server returns 304 Not Modified when the client's cached copy is still valid, saving bandwidth. ### Page Weight Inventory (F — 25/100) *120 resources · 6.9 MB · 925 KB savings available* - **[WARNING]** Page weight 6.9 MB exceeds 1 MB target by 5.9 MB - **[INFO]** ~925 KB of savings available - **[WARNING]** 119 third-party resources (100% of weight) - **[INFO]** 4 resources over 200KB ### Render-Blocking Resources (A+ — 100/100) *No render-blocking resources detected* - **[PASS]** No render-blocking resources detected in ### Third-Party Resources (A+ — 100/100) *No third-party resources detected* ### JavaScript Blocking (A — 90/100) *1 JS blocking issue(s) detected* - **[WARNING]** Total JS execution time is 16.4 s -- over the 3.5s budget — Total JavaScript execution (parse + compile + run) across all scripts exceeds 3.5 seconds. On low-end devices that becomes 7-15+ seconds and shows up directly in TBT and INP. Reduce by: tree-shaking unused dependencies, code-splitting (dynamic `import()`), removing or deferring third-party tracking, and replacing heavy frameworks where they're not needed. ### CSS Performance Depth (A+ — 100/100) *No CSS performance depth issues detected* - **[PASS]** No CSS performance depth issues detected --- ## Content Quality ### Links (A+ — 100/100) *1 links checked, 1 healthy, 0 broken* - **[PASS]** 1 of 1 links are healthy ### Mixed Content (A+ — 100/100) *No mixed content detected — all resources use HTTPS.* - **[PASS]** No mixed content detected — all resources use HTTPS ### Open Graph (F — 0/100) *No Open Graph tags found — social sharing previews will be generic.* - **[WARNING]** No Open Graph meta tags found — Without og:title, og:description, and og:image, social media platforms will generate a generic preview when your page is shared. ### Open Graph / Twitter Card Depth (A+ — 100/100) *No OG image or Twitter card set -- depth check is N/A (presence covered by Open Graph section)* - **[PASS]** No OG image / Twitter card to evaluate ### Structured Data (C — 40/100) *No structured data (JSON-LD) found.* - **[INFO]** No structured data (JSON-LD) found — Adding structured data helps search engines understand your content and can enable rich results. ### Rich Results Eligibility (C — 75/100) *No JSON-LD found -- no rich-result eligibility* - **[INFO]** No JSON-LD structured data on the page — No `
