## Security

### Security Headers (A+ — 95/100)

*9 of 10 headers properly configured*

- **[PASS]** HSTS is enabled with preload
- **[PASS]** X-Content-Type-Options is properly configured
- **[PASS]** X-Frame-Options is properly configured
- **[PASS]** Referrer-Policy is properly configured
- **[PASS]** Permissions-Policy is set
- **[PASS]** Content-Security-Policy is present
- **[PASS]** Cross-Origin-Opener-Policy is properly configured
- **[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 (A+ — 95/100)

*8 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
- **[INFO]** upgrade-insecure-requests is not set — This directive upgrades HTTP resources to HTTPS automatically, preventing mixed content.

### 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 61 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 (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 4 new-tab link(s) carry rel=noopener*

- **[PASS]** All 4 new-tab link(s) carry rel=noopener

### CSP Inline-Style Readiness (B — 90/100)

*1 inline style attribute(s) detected*

- **[INFO]** 1 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. 1 inline style(s) is low. Affected element types include: div. 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)

*Trusted Types enforced for 'script'*

- **[PASS]** Trusted Types enforced via require-trusted-types-for 'script'

### 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)

*No soft-404 patterns detected in page title or headings*

- **[PASS]** No soft-404 patterns detected in page title or headings

### 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 (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 (A+ — 100/100)

*100% high-risk feature coverage (10/10)*

- **[PASS]** Permissions-Policy covers 10/10 high-risk features (100%) — The Permissions-Policy header explicitly declares policies for 10/10 high-risk features.

Covered: camera, microphone, geolocation, payment, usb, serial, midi, accelerometer, gyroscope, magnetometer

Not declared (default-allow): 

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 `no-referrer` (strictest -- no Referer header sent at all)*

- **[PASS]** Referrer-Policy: `no-referrer` -- strictest -- no Referer header sent at all — The strictest setting: no `Referer` header is ever sent. Maximum privacy, but breaks referrer-based analytics and any cross-origin auth flow that relies on the Referer header. Use only when the page handles no referrer-dependent flows.

### Source Map Exposure (A+ — 100/100)

*No source maps accessible (probed 4 candidate URL(s))*

- **[PASS]** No source maps accessible across 4 probed candidate(s)

### HTML Version Disclosure (C — 75/100)

*1 software version(s) disclosed in HTML*

- **[WARNING]** 1 software version(s) disclosed in HTML: Hugo 0.160.1 — Each disclosed version enables direct CVE lookup -- an attacker who knows you run WordPress 6.4.2 (or whatever specific version) can search the CVE database for known exploits and target accordingly. Remove via your CMS config: WordPress (`remove_action('wp_head', 'wp_generator')`); Drupal (System / Reports / Status report -> Hide generator); Joomla (Global Configuration -> Hide generator); Hugo/Jekyll (delete or override the {{ .Site.Generator }} template hook). For HTML comments, audit your template files directly.

### 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 (B — 90/100)

*1 risky subdomain name(s) in certificate SANs*

- **[INFO]** 1 risky subdomain name(s) advertised in certificate SANs — These names are publicly visible via Certificate Transparency logs (crt.sh, censys.io) -- any attacker can enumerate them in seconds. Operators are often unaware that internal/staging/admin endpoints are inadvertently advertised this way. Mitigation: use a wildcard cert that doesn't enumerate, issue per-environment certs without non-prod SANs on the prod cert, or move internal services to private DNS off the public cert.

## 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*

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

### Email Security (D — 49/100)

*DMARC: quarantine, SPF: ~all*

- **[PASS]** DMARC policy is quarantine — good protection
- **[INFO]** DMARC configured without rua= aggregate reporting — Without rua=, you have no visibility into spoof attempts or auth failures from your own legitimate senders. Add rua=mailto:dmarc@<your-domain> (or a managed inbox at a reporting service).
- **[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).
- **[INFO]** No DKIM detected via common selectors — DKIM signs outbound mail to prove origin. We probed common selectors (default, google, selector1, etc.) without finding a record. If you use a non-standard selector, this is a false negative.
- **[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 (A+ — 100/100)

## Performance

### Page Weight Budget (A+ — 100/100)

*474 KB transferred, 12 requests*

- **[PASS]** Page weighs 597 KB (474 KB transferred)
- **[PASS]** 12 HTTP requests
- **[INFO]** Estimated 0.10 g CO2 per page load

### Third-Party Impact (A+ — 100/100)

*No third-party resources*

- **[PASS]** No third-party resources detected

### Text Compression (A+ — 100/100)

*All text resources are compressed*

- **[PASS]** All text resources are compressed

### Image Optimization (A+ — 95/100)

*1 images, 0 KB saveable*

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

### JS Execution Cost (A+ — 100/100)

*298ms total JS execution*

- **[INFO]** Unattributable: 171ms CPU time
- **[INFO]** https://erhoeremich.de/js/background-blur.min.605b...: 70ms CPU time
- **[INFO]** https://erhoeremich.de/: 56ms CPU time

### Font Loading (A+ — 100/100)

*1 fonts (87 KB)*

- **[INFO]** 1 font(s) use font-display: swap (FOUT risk but functional)

### JS Bundles (A+ — 100/100)

*4 scripts, 0 KB unused*


### 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.

### Document Compression (B — 80/100)

*Document response uses gzip; brotli would be ~20% smaller*

- **[INFO]** Main HTML response uses gzip (brotli would be ~20% smaller) — All current browsers support brotli. Most CDNs (Cloudflare, Fastly, AWS CloudFront, Vercel, Netlify) can switch from gzip to brotli with a single config flag. Origin servers (nginx, Apache) need a brotli module compiled in -- nginx-brotli or Apache mod_brotli.

### Asset Compression

*No text asset hosts to measure*

- **[INFO]** No third-party or subdomain host served enough text assets to measure — Asset compression is measured per host, from one HEAD request against a sampled resource. Pages that serve all their JS and CSS from the document's own origin are covered by the document compression check instead.

### 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+ — 100/100)

*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).
- **[PASS]** Both `ETag` and `Last-Modified` present -- efficient revalidation supported — The page returns both `ETag` (content hash) and `Last-Modified` (timestamp) headers. Browsers can issue conditional GETs with `If-None-Match` or `If-Modified-Since`; the server returns 304 Not Modified for unchanged content, saving bandwidth. ETag is the more reliable of the two (timestamps fail in DST transitions and clock skew).

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

*12 resources · 474 KB · 0 KB savings available*

- **[PASS]** Within 1MB page-weight target
- **[INFO]** 1 resources over 200KB

### 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 — 88/100)

*1 JS blocking issue(s) detected*

- **[WARNING]** 4 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+ — 100/100)

*No CSS performance depth issues detected*

- **[PASS]** No CSS performance depth issues detected

---

## Content Quality

### Links (A+ — 100/100)

*23 links checked, 23 healthy, 0 broken*

- **[PASS]** 23 of 23 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 (B — 85/100)

*Open Graph tags are partially configured — some improvements recommended.*

- **[WARNING]** Missing og:image — The og:image tag provides a preview image for social sharing.
- **[INFO]** og:title is short (13 characters) — Ideal length is 25–60 characters for social sharing previews.
- **[INFO]** og:description is short (52 characters) — Ideal length is 55–200 characters for social sharing previews.

### Open Graph / Twitter Card Depth (A+ — 100/100)

*OG image dimensions and Twitter card configuration look healthy*

- **[PASS]** OG/Twitter Card depth is clean -- dimensions, card type, and inheritance all valid

### Structured Data (A+ — 100/100)

*1 JSON-LD block(s) found — structured data is well configured.*

- **[INFO]** Missing recommended property "potentialAction" for WebSite — Adding "potentialAction" can improve how search engines display your content.

### Rich Results Eligibility (A+ — 100/100)

*1 JSON-LD block(s) declaring 1 schema type(s)*

- **[PASS]** 1 rich-result schema type(s) declared — Inventory of structured-data types on the page (each may unlock a different SERP feature):

WebSite

Search engines decide whether to render rich results based on content quality + page-level signals; declaring the schema is necessary but not sufficient.

### Image Optimization (F — 45/100)

*5 issues found across 2 images*

- **[WARNING]** 1 images missing explicit width/height — Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
- **[WARNING]** All 2 images use legacy formats (JPEG/PNG/GIF) — WebP offers 25-35% smaller files than JPEG. Use <picture> with <source type="image/webp"> for modern format support.
- **[WARNING]** 1 images missing alt text — Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.
- **[INFO]** 1 image(s) wider than 400px without srcset (no responsive serving) — These images deliver the same asset to every viewport (mobile, tablet, retina). Adding srcset / <picture> lets the browser pick a viewport-appropriate variant and typically saves 40-70% of bytes on mobile. Sample: https://erhoeremich.de/img/logo.png.
- **[INFO]** 1 image(s) rendered at a different aspect ratio than the source — The displayed dimensions distort the source -- CSS is forcing the image into a container at the wrong ratio, producing visible stretching or squashing. Either crop the source to match or use object-fit: cover (and accept the crop). Sample: https://erhoeremich.de/img/logo.png.

### 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, 41 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.
- **[PASS]** Has 1 IPv6 (AAAA) record(s)
- **[PASS]** 3 nameserver(s) configured
- **[PASS]** 1 mail exchanger(s) configured
- **[PASS]** SPF record present in TXT
- **[PASS]** DNS resolution time: 41 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)

*0/2 IPs match cert SAN*

- **[INFO]** PTR for 81.209.248.243 does not match any cert SAN: wp14.pixelx.cloud — 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.
- **[INFO]** PTR for 2001:7f0:3000:512::548:243 does not match any cert SAN: wp14.pixelx.cloud — 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 44ms across 3 resolvers (spread 12ms)*

- **[PASS]** Cloudflare: 38ms
- **[PASS]** Google: 44ms
- **[PASS]** Quad9: 50ms

### Redirect Chain (A+ — 100/100)

*No redirects — direct access*

- **[PASS]** No redirects — direct access

### IPv6 Readiness (F — 30/100)

*IPv6 records exist but unreachable*

- **[WARNING]** IPv6 DNS records exist but server is not reachable — Having AAAA records but an unreachable server is worse than no AAAA — clients may experience delays before falling back to IPv4.
- **[INFO]** IPv6 connection error

### Crawlability (A+ — 100/100)

*robots.txt present, sitemap with 3 URLs*

- **[PASS]** robots.txt is present
- **[PASS]** sitemap.xml is present
- **[PASS]** sitemap.xml is valid XML
- **[PASS]** sitemap.xml contains 3 entries
- **[PASS]** Sitemap index with 3 child sitemaps
- **[PASS]** robots.txt references sitemap

### URL Variants (B — 75/100)

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

- **[CRITICAL]** Both www and non-www versions serve content
- **[PASS]** HTTP correctly redirects to HTTPS permanently

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

*erhoeremich.de*

- **[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.

## Compliance

### WCAG Compliance (A+ — 100/100)

*No testable criteria*


### Cookie Consent & Privacy (B — 80/100)

*No consent signals detected*

- **[WARNING]** No privacy policy found (page links and common paths checked) — No link matching the privacy-policy vocabulary was found in the rendered page, and the common privacy-policy paths returned nothing. A privacy policy page is recommended for transparency and may be legally required.
- **[INFO]** No terms of service link detected
- **[INFO]** No cookie consent banner detected
- **[INFO]** This is an automated check, not legal advice — BeaverCheck detects technical indicators of consent management. This does not constitute a legal compliance assessment. Consult a privacy professional for GDPR/CCPA compliance.

### Consent UX Depth (A+ — 100/100)

*No consent-UX depth issues detected*

- **[PASS]** No consent-UX depth issues detected

### Tracker Inventory (A+ — 100/100)

*No known trackers detected on this page*

- **[INFO]** Language signals are inconsistent — The <html lang> attribute and Content-Language header should agree.

### Hreflang Configuration (A — 92/100)

*1 hreflang issue(s) across 3 tag(s)*

- **[INFO]** No `x-default` hreflang tag — Google recommends including `<link rel="alternate" hreflang="x-default" href="...">` so search engines have a fallback URL for users whose language / region doesn't match any specific hreflang entry. Typically points to a language-selection page or your default locale.

### Internationalization Extras (A+ — 100/100)

- **[PASS]** width=device-width is set
- **[PASS]** User zooming is allowed

### Accessibility Statement (B — 70/100)

*No accessibility statement detected*

- **[WARNING]** No accessibility statement detected — Sites are increasingly expected to publish an accessibility statement. Required by EU Web Accessibility Directive 2016/2102 for public-sector bodies; recommended best practice elsewhere. Common URLs: /accessibility, /accessibility-statement, /a11y. Detection is by link URL and anchor text, in a limited set of languages, so this is an unconfirmed absence.

## Availability

### CDN & Delivery (D — 50/100)

*No CDN (document or assets)*

- **[WARNING]** No CDN (document or assets) — Neither the HTML document nor the page's subresources are served through an edge network. A CDN can significantly improve load times for users around the world by caching content at edge nodes closer to them.

### HTTP Caching (D — 40/100)

*No cache headers*

- **[WARNING]** No Cache-Control header found — Browsers will use heuristic caching, which can be unpredictable. Set explicit cache headers.
- **[PASS]** ETag present — enables conditional (304) responses
- **[PASS]** Last-Modified header present

### 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 (includeSubDomains, preload)
- **[PASS]** HSTS preload enabled
- **[PASS]** TLS 1.3 in use (fastest handshake, 1-RTT)

### Health Check Endpoint (A+ — 95/100)

*Auth-protected health endpoint at https://erhoeremich.de/api/health (HTTP 403)*

- **[PASS]** Auth-protected health endpoint exposed at https://erhoeremich.de/api/health

### 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.

## Accessibility

### Landmark Structure (B — 70/100)

*6 landmarks*

- **[PASS]** <main> landmark present
- **[PASS]** 3 <nav> landmark(s) found
- **[WARNING]** 3 of 3 <nav> elements are unlabeled — Multiple navigations need aria-label to distinguish them for screen readers.

- **[INFO]** 1 heading(s) are all-uppercase (excluding short acronyms) — Headings rendered in all-uppercase are a styling choice that should be done via CSS (`text-transform: uppercase`), not by typing the text in caps. Capitalized text is read letter-by-letter by some screen readers (e.g., "H-E-L-L-O W-O-R-L-D" instead of "hello world"). It's also a soft signal of CMS-migration artifacts where the original lowercase intent was lost.
