## Security

### Security Headers (B — 70/100)

*6 of 10 headers properly configured*

- **[WARNING]** HSTS is enabled but 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.
- **[PASS]** Content-Security-Policy is present
- **[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 (B — 80/100)

*6 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 falls back to default-src
- **[PASS]** base-uri is properly restricted
- **[WARNING]** frame-ancestors directive is missing — frame-ancestors controls who can embed your page, preventing clickjacking. Set it to 'self' or 'none'.
- **[WARNING]** form-action directive is missing — form-action restricts where forms can submit data, preventing form hijacking.
- **[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, 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 52 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

### 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)

*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) (B — 95/100)

*Trusted Types not enabled*

- **[INFO]** Trusted Types not enabled — Trusted Types (CSP3) is a Chrome 83+ defense that requires DOM-XSS sinks (innerHTML, document.write, eval, ...) to receive a typed-and-sanitized value rather than a raw string. Adding `Content-Security-Policy: require-trusted-types-for 'script'; trusted-types default` neutralizes most DOM-XSS even when a payload reaches a sink. Adoption is currently ~0.1% of pages so this is informational; a roll-out usually starts in report-only mode.

### 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 (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 `<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 5 examples):
  - //heatmaps.monsido.com/v1/heatmaps.js
  - //pagecorrect.monsido.com/v1/page-correct.js
  - https://meldingen.brabantalert.nl/public/widget/97830615e36300bb14c30992096f4a03.js?cookie=false
  - https://app-script.monsido.com/v2/monsido-script.js
  - https://analytics.silktide.com/d72f4b285a2f4ea86cd5dc508cffe267.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 (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 (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)

*No source maps accessible (probed 1 candidate URL(s))*

- **[PASS]** No source maps accessible across 1 probed candidate(s)

### HTML Version Disclosure (B — 90/100)

*1 generator tag(s) without version info*

- **[INFO]** 1 generator tag(s) without version info: TYPO3 CMS — Generator tags reveal the CMS / build tool but no version specifics. Attackers can't directly cross-reference CVEs but can probe known weaknesses for the named platform. Removing the tag entirely is preferable; most CMSes have a one-config-flag option to suppress it.

### 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 7 external resources have SRI*

- **[WARNING]** External script from heatmaps.monsido.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from pagecorrect.monsido.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from meldingen.brabantalert.nl lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from app-script.monsido.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from analytics.silktide.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External link from app.tolkie.nl lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from app.tolkie.nl 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 (F — 12/100)

*no DMARC, SPF: ~all*

- **[WARNING]** No DMARC record found — Without DMARC, email receivers have no policy for handling authentication failures. Add a TXT record at _dmarc.<domain> starting with v=DMARC1.
- **[WARNING]** SPF evaluation problem: exceeded RFC 7208 10-lookup limit (counted 11 lookup(s)) — Receivers PERMERROR-fail SPF evaluation when the include/redirect tree exceeds the RFC 7208 10-lookup cap or contains a pathological structure. This is one of the most common silent SPF failures. Flatten the tree by inlining ip4: / ip6: addresses for senders you control, or use a macro-based ESP solution.
- **[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 (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 — 33/100)

*2.8 MB transferred, 71 requests*

- **[WARNING]** Page weighs 7.5 MB (2.8 MB transferred)
- **[WARNING]** JavaScript is 1004 KB — consider code splitting or lazy loading — Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.
- **[INFO]** Fonts are 1004 KB — consider subsetting or using system fonts — Subset fonts to include only used characters, or switch to system font stacks.
- **[INFO]** 71 HTTP requests
- **[INFO]** Estimated 0.58 g CO2 per page load

### Third-Party Impact (A — 85/100)

*24% third-party, 0 ms blocking*

- **[INFO]** Third-party code accounts for 24% of page weight (694.8 KiB of 2.8 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 — 70/100)

*43 images, 0 KB saveable*

- **[WARNING]** https://www.asten.nl/fileadmin/_processed_/7/6/csm... is missing width/height — may cause layout shift — Set explicit width and height to prevent CLS.

### JS Execution Cost (C — 60/100)

*1837ms total JS execution*

- **[WARNING]** Unattributable: 683ms CPU time
- **[WARNING]** https://www.asten.nl/typo3temp/assets/compressed/m...: 550ms CPU time
- **[WARNING]** https://www.asten.nl/: 282ms CPU time
- **[WARNING]** https://app.tolkie.nl/: 258ms CPU time
- **[INFO]** https://analytics.silktide.com/d72f4b285a2f4ea86cd...: 64ms CPU time
- **[INFO]** Third-party scripts: 322ms (18% of total)

### Font Loading (A+ — 100/100)

*4 fonts (1004 KB)*

- **[INFO]** 4 font(s) use font-display: swap (FOUT risk but functional)

### JS Bundles (F — 30/100)

*10 scripts, 374 KB unused*

- **[WARNING]** https://www.asten.nl/typo3temp/assets/compressed/m...: 316 KB unused (69%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://www.asten.nl/typo3temp/assets/compressed/m...: unminified — 199 KB could be saved
- **[WARNING]** https://www.asten.nl/stats/matomo.js: 38 KB unused (56%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://app.tolkie.nl/: 20 KB unused (11%) — Consider code splitting or tree shaking to reduce unused code.
- **[INFO]** Total unused JavaScript: 374 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.

### 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 (A+ — 100/100)

*All 1 asset host use brotli*

- **[PASS]** app.tolkie.nl serves assets with brotli (assets: 3)

### 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 (A+ — 100/100)

*Main HTML uses no-store -- correct for sensitive/dynamic content*

- **[PASS]** Main HTML uses no-store -- correct for sensitive/dynamic content

### 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 (C — 55/100)

*71 resources · 2.8 MB · 374 KB savings available*

- **[WARNING]** Page weight 2.8 MB exceeds 1 MB target by 1.8 MB
- **[INFO]** ~374 KB of savings available
- **[INFO]** 22 third-party resources (24% of weight)
- **[INFO]** 7 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 (B — 80/100)

*1 JS blocking issue(s) detected*

- **[WARNING]** 5 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)

*78 links checked, 78 healthy, 0 broken*

- **[PASS]** 78 of 78 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)

*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 (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 (D — 60/100)

*4 issues found across 32 images*

- **[WARNING]** 6 images missing explicit width/height — Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
- **[INFO]** 30 below-fold images missing loading="lazy" — Lazy loading defers below-fold images, reducing initial page weight.
- **[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.
- **[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://www.asten.nl/fileadmin/_processed_/c/0/csm_Raadzaal_foto_22fede9a0d.png.

### Autoplay Media (A+ — 100/100)

*No autoplay media on the page*

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

---

## Infrastructure

### DNS Records (A — 85/100)

*1 A records, 92 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)
- **[WARNING]** CNAME record at zone apex — A CNAME at the zone apex can break MX and NS records. Use ALIAS/ANAME or A records instead.
- **[PASS]** 4 nameserver(s) configured
- **[PASS]** 1 mail exchanger(s) configured
- **[PASS]** SPF record present in TXT
- **[PASS]** DNS resolution time: 92 ms

### Subdomain Takeover (A+ — 100/100)

*No subdomain takeover risk detected*

- **[PASS]** CNAME does not point at a known takeover-able service

### DNSSEC (A+ — 100/100)

*Signed and validating*

- **[PASS]** DNSSEC fully signed and chain validates (ECDSAP256SHA256)

### 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 90.145.213.25 does not match any cert SAN: 90-145-213-25.bbserv.nl — 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 lookup failed for 2a02:120:380:1::1:124: lookup 2a02:120:380:1::1:124: no such host — No reverse DNS record set for this IP. Common on bare cloud-VM IPs without provider-side PTR; not a security issue.

### Multi-Resolver DNS Speed (A — 90/100)

*Mean 54ms across 3 resolvers (spread 66ms)*

- **[PASS]** Google: 20ms
- **[PASS]** Cloudflare: 58ms
- **[PASS]** Quad9: 86ms

### Redirect Chain (A+ — 100/100)

*No redirects — direct access*

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

### IPv6 Readiness (A+ — 100/100)

*IPv6 reachable (34 ms)*

- **[PASS]** IPv6 is configured and reachable at 2a02:120:380:1::1:124

### Crawlability (A+ — 95/100)

*robots.txt present, sitemap with 1 URLs*

- **[PASS]** robots.txt is present
- **[PASS]** sitemap.xml is present
- **[PASS]** sitemap.xml is valid XML
- **[PASS]** sitemap.xml contains 1 entries
- **[PASS]** Sitemap index with 1 child sitemaps
- **[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 — 90/100)

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

- **[PASS]** www/non-www redirect configured correctly (preferred: www)
- **[WARNING]** HTTP→HTTPS redirect is not permanent

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

*asten.nl — via Systemec B.V., 29 years old*

- **[PASS]** DNSSEC is enabled
- **[PASS]** Registrar: Systemec B.V.
- **[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.

### 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.

### GDPR Article 13 Disclosures (D — 50/100)

*0 / 8 Art. 13 categories matched in homepage body*

- **[INFO]** GDPR Article 13 disclosures not assessed (policy language: nl) — The privacy policy appears to be written in "nl", which this check has no disclosure patterns for (currently English, French, German and Spanish).

### Copyright Notice (C — 55/100)

*No copyright notice detected*

- **[INFO]** No copyright notice detected — No copyright notice detected in the page content. While not legally required in most jurisdictions (copyright exists automatically), a notice is standard practice and signals site ownership.

### Regulatory Indicators

*1 regulatory indicator(s) detected*

- **[INFO]** This is a technical scan, not a legal assessment — BeaverCheck detects technical indicators that may suggest regulatory relevance. This is not a compliance audit and should not be relied upon for legal decisions. Consult qualified legal counsel for compliance assessments.
- **[INFO]** GDPR indicators detected (strong confidence) — Indicators suggesting GDPR may be relevant: European language detected: nl-NL; European TLD detected: .nl; Privacy policy page found. EU General Data Protection Regulation — governs collection and processing of personal data of EU residents.

### Third-Party Data Sharing

*0 third-party service(s) detected*

- **[INFO]** Data inventory for transparency purposes — This inventory identifies third-party services that receive data from your site visitors. Under regulations like GDPR (Article 30), maintaining records of data processing activities is commonly considered a best practice. This automated scan provides a starting point — it may not capture all data flows.
- **[INFO]** No recognized third-party data-sharing services detected — This page does not appear to load external tracking, analytics, or advertising scripts.

## Availability

### CDN & Delivery (C — 65/100)

*Assets on AWS CloudFront (host app.tolkie.nl, 3 assets); document served directly from origin*

- **[WARNING]** Document not behind existing CDN (AWS CloudFront serves the assets) — The page's subresources are delivered by AWS CloudFront (app.tolkie.nl, 3 assets), but the HTML document itself comes straight from the origin. Routing the document through the CDN already in use is the cheapest latency win available here -- the provider relationship, the certificate and the config already exist. A short edge TTL with stale-while-revalidate suits HTML that changes often; if the response is genuinely per-user, edge TLS termination alone still removes a full round trip from every visitor's first byte.
- **[PASS]** Assets on AWS CloudFront: app.tolkie.nl (assets: 3), cache Hit from cloudfront

### HTTP Caching (D — 40/100)

*no-store (uncacheable)*

- **[INFO]** Cache-Control: no-store prevents all caching — Intentional for dynamic content, but increases server load for every page view.
- **[INFO]** No ETag or Last-Modified header — Conditional requests (304 Not Modified) are not possible without validators.

### 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.

## Accessibility

### Landmark Structure (B — 75/100)

*5 landmarks*

- **[PASS]** <main> landmark present
- **[PASS]** 2 <nav> landmark(s) found
- **[WARNING]** 1 of 2 <nav> elements are unlabeled — Multiple navigations need aria-label to distinguish them for screen readers.
- **[WARNING]** Skip navigation link is missing (WCAG 2.4.1) — Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.

### Heading Hierarchy (A+ — 100/100)

*26 headings*

- **[PASS]** Single H1 present

### Heading Text Quality (A+ — 100/100)

*All 26 heading(s) have substantive, well-formed text*

- **[PASS]** Heading text quality is clean -- no placeholder, length, or styling issues

*All tap targets meet WCAG 2.5.5/2.5.8 sizing*

- **[PASS]** All tap targets meet WCAG 2.5.5 (44x44px) sizing

### Mobile-Readable Font Sizes (B — 90/100)

*98% of visible text renders at >= 12 CSS px (1 below threshold)*

- **[INFO]** 1 text node(s) render below 12 CSS pixels on mobile — Mobile browsers default the root font-size to 16 px; text below ~ 12 px (75% of root) is hard to read without zooming. WCAG 1.4.4 (Resize Text) requires the page to support 200% zoom without loss of functionality -- which most layouts handle, but small base text still costs readability and conversion. Audit which selectors set sizes below 12 px (often footers, fine print, table cells) and bump them to 14-16 px or use rem units that scale with user preferences. Examples: <span> 10.0px ("Menu").

- **[PASS]** SVG favicon detected — scales perfectly to any size

### Web Manifest (D — 40/100)

*Not found*

- **[INFO]** No web manifest found — No manifest at standard paths (/manifest.json, /site.webmanifest). A manifest is optional but enables PWA features like home screen installation and standalone display.

### PWA Depth (A+ — 100/100)

*No PWA depth issues detected*

- **[PASS]** No PWA depth issues detected

### Dark Mode Support (D — 40/100)

- **[INFO]** No dark mode signals detected — Consider adding CSS with @media (prefers-color-scheme: dark) and <meta name='color-scheme' content='light dark'>.
- **[INFO]** Detection limited to meta tags and inline styles — External CSS files may contain prefers-color-scheme rules not visible to this scan.

### Print Stylesheet (D — 40/100)

*No print styles*

- **[INFO]** No print-specific styles detected — When users print this page, they get the screen layout including navigation and non-essential elements. Add @media print rules to hide navigation and optimize layout for paper.

### Navigation UX (F — 15/100)

*No navigation patterns*

- **[PASS]** 2 navigation landmark(s) detected
- **[INFO]** No breadcrumbs, search, or skip link detected — These navigation aids help users orient themselves and find content efficiently, especially on large sites.

## Sustainability

### CO2 Per Page Load (B — 70/100)

*0.79g CO2 per view*

- **[INFO]** 0.79g CO2 per page view — This page transfers 2.8 MB, producing an estimated 0.79g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 0.15g, network 0.14g, end-user device 0.51g.
- **[INFO]** At 10,000 monthly views: 94.4 kg CO2/year — With 10,000 page views per month, this page would generate approximately 94.4 kg of CO2 annually — equivalent to charging 11805 smartphones.

### Green Hosting (D — 40/100)

*Not green*

- **[INFO]** No confirmed renewable energy commitment detected — Consider providers like Cloudflare, Google Cloud, or Vercel that match 100% of their energy use with renewables.
- **[INFO]** Green hosting status based on known provider commitments — Green hosting detection uses a curated database of provider renewable energy commitments. This is not a real-time verification. For authoritative checks, visit thegreenwebfoundation.org.

### Repeat Visit Weight (A+ — 100/100)

*100% cached*

- **[PASS]** 100% reduction on repeat visits — Returning visitors download only 9 KB (vs 2845 KB first visit). 69 of 71 resources are served from browser cache, saving 0.78g CO2 per repeat visit.
- **[INFO]** Repeat visit: 0.00g CO2 (first visit: 0.79g)

### Carbon Budget (D — 50/100)

*55th percentile*

- **[WARNING]** 0.79g CO2 — above the median website (0.60g) — Heavier than an estimated 45% of websites. Reducing page weight, optimizing images, and removing unused JavaScript would lower the carbon footprint. See the Performance tab.
- **[INFO]** Estimated 55th percentile — Compared to: top 10% = 0.20g, target = 0.50g, median = 0.60g per page view.

### Transfer Efficiency (B — 80/100)

*87% efficient*

- **[INFO]** Transfer efficiency: 87% — An estimated 373 KB (13%) could be eliminated: 0 KB via better compression, 0 KB via modern image formats, 373 KB of unused JavaScript. This wasted data produces 0.10g of unnecessary CO2 per page view.

### Web Font Weight Variants (B — 90/100)

*No detectable Google Fonts weights*

- **[INFO]** No detectable Google Fonts weights — The analyzer detects font weights via Google Fonts URL parameters (~70% of font-using sites). Self-hosted fonts and non-Google CDN fonts aren't visible to URL-based detection. If you self-host fonts, manually audit how many @font-face weights you ship -- 2-3 weights per family is typically enough; 5+ is usually unused payload.
