## Security

### Security Headers (C — 55/100)

*5 of 10 headers properly configured*

- **[WARNING]** HSTS is missing includeSubDomains — Without includeSubDomains, subdomains can still be accessed over HTTP.
- **[PASS]** X-Content-Type-Options is properly configured
- **[PASS]** X-Frame-Options is properly configured
- **[PASS]** Referrer-Policy is properly configured
- **[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
- **[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, 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 59 days)
- **[PASS]** Certificate chain has 2 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 (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 (C — 60/100)

*No security.txt file found*

- **[INFO]** No security.txt file found — security.txt (RFC 9116) provides a standardized way for security researchers to report vulnerabilities. Create one at /.well-known/security.txt with at least a Contact field.

### Cross-Origin Tab Safety (A+ — 100/100)

*All 9 new-tab link(s) carry rel=noopener*

- **[PASS]** All 9 new-tab link(s) carry rel=noopener

### CSP Inline-Style Readiness (C — 75/100)

*31 inline style attribute(s) detected*

- **[WARNING]** 31 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. 31 inline style(s) is moderate. Affected element types include: div, ul, svg, figure, h3. 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 (0/3 third-party resources)*

- **[WARNING]** SRI adoption: 0/3 third-party resources protected (0%) — Of 3 third-party `<script>` / `<link rel=stylesheet>` resources, 0 (0%) declare a Subresource Integrity hash via the `integrity=` attribute. SRI binds the page to the exact bytes of the third-party resource: if the CDN is compromised, attacker-modified bytes won't match the declared hash and the browser refuses to execute the resource.

Missing SRI on (first 3 examples):
  - https://consent.cookiebot.com/26772e78-659e-4424-a95b-9b89f6bceb65/cc.js?renew=false&referer=www.bzh-freiburg.de&dnt=false&init=false&culture=en
  - https://consentcdn.cookiebot.com/consentconfig/26772e78-659e-4424-a95b-9b89f6bceb65/bzh-freiburg.de/configuration.js
  - https://consent.cookiebot.com/uc.js

Fix: add `integrity="sha384-..."` and `crossorigin="anonymous"` attributes. Generators: srihash.org, or in-browser via `await crypto.subtle.digest('SHA-384', bytes)`. Cache-bust the resource URL when you change versions, since the integrity hash will mismatch with old cached bytes.

### 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 (F — 35/100)

*0% high-risk feature coverage (0/10)*

- **[WARNING]** Permissions-Policy covers 0/10 high-risk features (0%) — The Permissions-Policy header explicitly declares policies for 0/10 high-risk features.

Covered: 

Not declared (default-allow): camera, microphone, geolocation, payment, usb, serial, midi, accelerometer, gyroscope, magnetometer

The non-declared features fall back to their spec-default policy (usually `self`), which means an XSS-injected or compromised iframe could request them. For features the page genuinely doesn't use, declare `feature=()` to fully close them.

### Referrer-Policy Strictness (A+ — 100/100)

*Referrer-Policy is `same-origin` (strict -- Referer sent only on same-origin requests)*

- **[PASS]** Referrer-Policy: `same-origin` -- strict -- Referer sent only on same-origin requests — Full URL Referer header on same-origin requests; no Referer at all on cross-origin. Strong privacy posture; same-origin analytics still work.

### 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 (F — 20/100)

*0 of 3 external resources have SRI*

- **[WARNING]** External script from consent.cookiebot.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from consentcdn.cookiebot.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from consent.cookiebot.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*

- **[INFO]** No security.txt found — Consider adding a security.txt at /.well-known/security.txt.
- **[PASS]** No sensitive files exposed

### Email Security (A — 90/100)

*DMARC: reject, SPF: -all, DKIM*

- **[PASS]** DMARC policy is reject — strongest protection
- **[PASS]** SPF ends in -all (hard fail) — strongest setting
- **[PASS]** DKIM configured (selectors: selector1, selector2, s1, s2)
- **[INFO]** MTA-STS not configured — MTA-STS forces inbound mail to use TLS, preventing downgrade attacks. Requires both a TXT record at _mta-sts.<domain> and a policy file at https://mta-sts.<domain>/.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.<domain>.
- **[INFO]** BIMI not configured — BIMI (Brand Indicators for Message Identification) lets supporting clients (Gmail, Apple Mail, Yahoo) display your verified logo next to your messages. Optional but raises trust signals. Requires DMARC at p=quarantine or p=reject to be honored.

### 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 (C — 60/100)

*0 directives, 5 missing*

- **[INFO]** camera not restricted — Consider adding camera=() to block camera access from embedded content.
- **[INFO]** microphone not restricted — Consider adding microphone=() to block microphone access from embedded content.
- **[INFO]** geolocation not restricted — Consider adding geolocation=() to block geolocation access from embedded content.
- **[INFO]** payment not restricted — Consider adding payment=() to block payment access from embedded content.

*914 KB transferred, 30 requests*

- **[PASS]** Page weighs 2.0 MB (914 KB transferred)
- **[PASS]** 30 HTTP requests
- **[INFO]** Estimated 0.19 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 (913.7 KiB of 914.0 KiB)
- **[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 (A+ — 95/100)

*11 images, 0 KB saveable*

- **[PASS]** All images are well-optimized

### JS Execution Cost (C — 60/100)

*1037ms total JS execution*

- **[WARNING]** https://consent.cookiebot.com/uc.js: 424ms CPU time
- **[WARNING]** Unattributable: 341ms CPU time
- **[WARNING]** https://www.bzh-freiburg.de/en: 273ms CPU time
- **[WARNING]** Third-party scripts: 1037ms (100% of total)

### Font Loading (A+ — 100/100)

*3 fonts (131 KB)*

- **[INFO]** 3 font(s) use font-display: swap (FOUT risk but functional)

### JS Bundles (B — 80/100)

*7 scripts, 74 KB unused*

- **[WARNING]** https://consent.cookiebot.com/26772e78-659e-4424-a...: 26 KB unused (25%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://www.bzh-freiburg.de/vendor/swiper/swiper-b...: 24 KB unused (60%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://www.bzh-freiburg.de/vendor/swiper/swiper-b...: 24 KB unused (60%) — Consider code splitting or tree shaking to reduce unused code.
- **[INFO]** Total unused JavaScript: 74 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 — 85/100)

*4 hints, 0 missing preconnects*

- **[WARNING]** 3 font preload(s) missing `crossorigin` -- font will be downloaded twice — Fonts are always fetched as crossorigin=anonymous; a preload without the attribute creates a different cache key, so the browser refetches when the actual font request happens. Sample: /fonts/dbcfebeb-81b6-4dd3-912a-c4fc1bb8b8dc.woff2, /fonts/3a9dc726-d61e-48d0-86ba-9548f35b5625.woff2, /fonts/3ca076a2-34ad-4c48-a029-02536a509f22.woff2. Add `crossorigin` (or `crossorigin="anonymous"`) to each preload.
- **[PASS]** Page uses 4 resource hint(s)

### 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 — 80/100)

*No Cache-Control header on main HTML response*

- **[INFO]** Main HTML response has no Cache-Control header — Without an explicit Cache-Control, browsers fall back to heuristic caching (~10% of Last-Modified age). Set `Cache-Control: no-cache` or `max-age=300` for HTML to control freshness explicitly -- prevents stale auth state and SPA shell drift.

### Server-Timing Observability (B — 85/100)

*No Server-Timing header found*

- **[INFO]** No Server-Timing header found — Server-Timing exposes backend timing breakdowns to browser DevTools (e.g., `db: 45ms; render: 120ms; cache: 2ms`). Useful for diagnosing slow pages without backend log access. Most modern frameworks (Next.js, Cloudflare Workers, Fastly) emit it automatically; absence on a managed platform usually means telemetry headers are stripped at the edge.

### Server Response Intelligence (A+ — 95/100)

*2 server-response signal(s) detected*

- **[PASS]** `Vary` header declared: Accept-Encoding — The page declares a `Vary` header, telling downstream caches which request headers the response varies on. Critical for content-negotiated responses (compression, language, cookies, device class).
- **[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: "<hash>"` (or `Last-Modified: <date>`) on cacheable responses; the server returns 304 Not Modified when the client's cached copy is still valid, saving bandwidth.

### Page Weight Inventory (A — 85/100)

*30 resources · 914 KB · 74 KB savings available*

- **[PASS]** Within 1MB page-weight target
- **[INFO]** ~74 KB of savings available
- **[WARNING]** 29 third-party resources (100% of weight)

### Render-Blocking Resources (A+ — 100/100)

*No render-blocking resources detected*

- **[PASS]** No render-blocking resources detected in <head>

### Third-Party Resources (A+ — 100/100)

*No third-party resources detected*


### JavaScript Blocking (A — 94/100)

*1 JS blocking issue(s) detected*

- **[WARNING]** 2 render-blocking <script src> tag(s) without async/defer — Each `<script src=...>` without `async`, `defer`, or `type="module"` blocks HTML parsing while the browser fetches and executes it. The block lasts the entire round-trip + execution time -- on slow networks this translates directly into LCP delay. Add `defer` (executes after parse, in source order) for scripts that interact with the DOM, or `async` (executes whenever ready) for analytics / independent scripts. Module scripts (`type="module"`) are deferred by default.

### CSS Performance Depth (A — 90/100)

*1 CSS depth issue(s) detected*

- **[WARNING]** 1 `@font-face` rule(s) without `font-display` -- causes FOIT — An `@font-face` rule without `font-display` causes Flash of Invisible Text (FOIT): the browser hides the styled text for up to 3 seconds while the custom font downloads, then either swaps to fallback (Chrome / Firefox) or stays invisible (older Safari). Add `font-display: swap` (shows fallback immediately, swaps in the custom font when ready) or `font-display: optional` (uses fallback if the font isn't ready in 100ms; never causes visible swap). Either eliminates FOIT outright.

---

## Content Quality

### Links (A+ — 98/100)

*47 links checked, 46 healthy, 0 broken*

- **[PASS]** 46 of 47 links are healthy
- **[INFO]** Long redirect chain: https://bzh-freiburg.de/instagram (3 hops)

### 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 `<script type="application/ld+json">` blocks found. Without structured data, search engines fall back to inferring page meaning from raw HTML -- which works but doesn't unlock SERP features (rich snippets, knowledge panel, FAQ accordion, breadcrumb trail). Adding even basic JSON-LD (Organization for the site identity, BreadcrumbList for navigation context) is a low-effort SEO win.

### Image Optimization (F — 35/100)

*5 issues found across 14 images*

- **[WARNING]** 1 images significantly larger than display size — Resizing to display dimensions could save approximately 0 KB.
- **[WARNING]** 6 images missing explicit width/height — Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
- **[INFO]** 6 below-fold images missing loading="lazy" — Lazy loading defers below-fold images, reducing initial page weight.
- **[WARNING]** 7 images missing alt text — Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.
- **[WARNING]** 7 above-fold image(s) marked loading="lazy" (LCP anti-pattern) — Above-fold images marked lazy delay LCP -- the browser waits for the IntersectionObserver to fire before fetching, even though the image is in the initial viewport. Remove `loading="lazy"` on above-the-fold images (especially the LCP candidate). Sample: https://www.bzh-freiburg.de/_default_upload_bucket/2383/image-thumb__2383__heroSliderImage/Pagehero%20Vorlage%20960%20x%20540%20%281%29_3~-~media--c8c13032--query.avif, https://www.bzh-freiburg.de/_default_upload_bucket/2367/image-thumb__2367__heroSliderImage/Kongresser%C3%B6ffnung%20%285%29~-~media--c8c13032--query.avif, https://www.bzh-freiburg.de/_default_upload_bucket/1925/image-thumb__1925__heroSliderImage/Pagehero-Vinzenz_Video~-~media--c8c13032--query.avif (+4 more).

### Autoplay Media (A+ — 100/100)

*No autoplay media on the page*

- **[PASS]** No autoplay media on the page

## Infrastructure

### DNS Records (A+ — 95/100)

*1 A records, 42 ms lookup*

- **[PASS]** Resolves to 1 IPv4 address(es)
- **[INFO]** Single A record — no DNS redundancy — Multiple A records provide failover if one server goes down.
- **[INFO]** No IPv6 (AAAA) records
- **[PASS]** 3 nameserver(s) configured
- **[PASS]** 1 mail exchanger(s) configured
- **[PASS]** SPF record present in TXT
- **[PASS]** DNS resolution time: 42 ms

### Subdomain Takeover (A+ — 100/100)

*No subdomain takeover risk detected*

- **[PASS]** No CNAME record present

### DNSSEC (B — 80/100)

*Unsigned (DNSSEC not deployed)*

- **[INFO]** DNSSEC is not deployed — The zone is not DNSSEC-signed. Users on validating resolvers (Cloudflare 1.1.1.1, Quad9 9.9.9.9, growing default in mobile resolvers) get no protection against DNS spoofing for this domain. Most registrars now offer DNSSEC at a single click; consider enabling it for sites where authenticity matters (banking, healthcare, government).

### CAA Records (B — 80/100)

*No CAA records (any CA may issue certificates)*

- **[INFO]** No CAA records published — Without CAA records, any publicly-trusted CA can issue certificates for this domain. Adding a CAA record (`yourdomain. IN CAA 0 issue "letsencrypt.org"`) restricts issuance to CAs you authorize. Required by CAB Forum baseline since 2017; the default of 'any CA' is widely supported but is the broader attack surface for issuance fraud.

### Reverse DNS (B — 75/100)

*0/1 IPs match cert SAN*

- **[INFO]** PTR for 188.40.83.227 does not match any cert SAN: awhzds9.aufwind-solutions.de — Common when behind a CDN or shared hosting (PTR points at the provider's hostname). Mismatch can also affect mail deliverability if this IP sends email -- many MTAs reject mail when forward+reverse DNS disagree.

### Multi-Resolver DNS Speed (A+ — 100/100)

*Mean 43ms across 3 resolvers (spread 20ms)*

- **[PASS]** Google: 31ms
- **[PASS]** Cloudflare: 47ms
- **[PASS]** Quad9: 51ms

### Redirect Chain (B — 70/100)

*2 redirect(s), 568 ms total*

- **[WARNING]** 2 redirects before reaching final URL — Each redirect adds latency. Try to minimize the chain to 1 hop.
- **[INFO]** WWW normalization redirect
- **[INFO]** Redirect overhead: 568 ms total

### IPv6 Readiness (C — 60/100)

*No IPv6 support*

- **[INFO]** No IPv6 (AAAA) records found — IPv6 support is increasingly important for global accessibility. About 40% of internet users have IPv6 connectivity.

### Crawlability (A+ — 95/100)

*robots.txt present, sitemap with 148 URLs*

- **[PASS]** robots.txt is present
- **[PASS]** sitemap.xml is present
- **[PASS]** sitemap.xml is valid XML
- **[PASS]** sitemap.xml contains 148 entries
- **[INFO]** robots.txt does not reference a sitemap — Add a 'Sitemap:' directive to robots.txt so search engines can discover your sitemap.

### URL Variants (A+ — 100/100)

*www/non-www, trailing slash, HTTP→HTTPS*

- **[PASS]** www/non-www redirect configured correctly (preferred: non-www)
- **[PASS]** HTTP correctly 301-redirects to HTTPS

### Domain Intelligence (A+ — 100/100)

*bzh-freiburg.de — hosted on Hetzner*

- **[WARNING]** Registrar lock is NOT enabled — The domain can be transferred without an unlock step. Enable registrar lock (clientTransferProhibited) in your registrar's control panel to protect against unauthorized or accidental transfers.
- **[PASS]** Hosting: Hetzner

## Availability

### CDN & Delivery (D — 50/100)

*No CDN detected*

- **[WARNING]** No CDN detected — A CDN can significantly improve load times for users around the world by caching content at edge nodes closer to them.

### HTTP Caching (F — 30/100)

*No cache headers*

- **[WARNING]** No Cache-Control header found — Browsers will use heuristic caching, which can be unpredictable. Set explicit cache headers.

### Operational Status Page (B — 80/100)

*No status page link detected*

- **[INFO]** No operational status page link detected — Status pages communicate planned maintenance and incidents to users -- a hallmark of operationally-mature services. Most SaaS teams publish one via Atlassian Statuspage, Instatus, BetterUptime, or a self-hosted Cachet. Smaller sites legitimately don't need one; flagged as Info, not a failure.

### Transport Security (A — 90/100)

*HTTP/3, HSTS, and TLS version analysis*

- **[INFO]** HTTP/3 (QUIC) not advertised — HTTP/3 eliminates head-of-line blocking. If your CDN supports it, consider enabling it.
- **[PASS]** HSTS enabled (base policy)
- **[INFO]** HSTS missing includeSubDomains — Without includeSubDomains, HSTS only protects the exact domain.
- **[PASS]** TLS 1.3 in use (fastest handshake, 1-RTT)

### Health Check Endpoint (B — 80/100)

*No conventional health endpoint found*

- **[INFO]** No conventional health endpoint found — Health endpoints (/health, /healthz, /status, /ping, /api/health) let uptime monitors, load balancers, and orchestration systems (Kubernetes, ECS, Fly.io) verify the service is alive. Marketing sites and small services often skip them legitimately; flagged as Info, not a failure. Probe results: /api/health: 404, /health: 404, /healthz: 404, /ping: 404, /status: 404.

### CDN Cache Observability (B — 85/100)

*No CDN cache-status headers in the response*

- **[INFO]** No CDN cache-status headers in the response — Without an X-Cache / CF-Cache-Status / X-Vercel-Cache / Age header, you can't tell from outside whether a request hit the cache or went to origin. Operationally important: enables debugging stale-content reports and verifying cache rules. Most managed CDN platforms emit at least one of these by default; absence often means the platform's diagnostic headers are stripped at an upstream proxy.
