## Security

### Security Headers (F — 30/100)

*4 of 10 headers properly configured*

- **[CRITICAL]** HSTS header is missing — Strict-Transport-Security forces browsers to use HTTPS, preventing downgrade attacks. Add the header with a max-age of at least 1 year.
- **[PASS]** X-Content-Type-Options is properly configured
- **[WARNING]** X-Frame-Options header is missing — This header prevents clickjacking by controlling who can embed your page in a frame. Set it to DENY or SAMEORIGIN.
- **[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, 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 86 days)
- **[PASS]** Certificate chain has 3 certificates
- **[PASS]** Certificate uses modern signature algorithm
- **[PASS]** Certificate covers 1 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 (A — 90/100)

*Cloudflare*

- **[PASS]** Cloudflare detected — Detected via: cf-ray: 9f989def5cc6db93-CDG

### 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 (C — 75/100)

*22 inline style attribute(s) detected*

- **[WARNING]** 22 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. 22 inline style(s) is moderate. Affected element types include: nav, div, ins, iframe. 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)

*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 (0/6 third-party resources)*

- **[WARNING]** SRI adoption: 0/6 third-party resources protected (0%) — Of 6 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):

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 — 90/100)

*1 CORS depth signal(s) detected*

- **[INFO]** CORS allows any origin (`Access-Control-Allow-Origin: *`) — Any website can fetch this URL via JavaScript and read the response body. Acceptable for genuinely public APIs (e.g. CDN-served static assets). Risky if the URL returns user-specific or session-derived data, since other origins can scrape it via the user's browser without needing credentials. Narrow Allow-Origin to a specific origin allow-list when the response is sensitive.

### 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 `strict-origin-when-cross-origin` (modern default -- full URL same-origin, origin-only cross-origin)*

- **[PASS]** Referrer-Policy: `strict-origin-when-cross-origin` -- modern default -- full URL same-origin, origin-only cross-origin — The modern browser default (Chrome 85+, Firefox 87+, Safari 15+). Full URL Referer on same-origin; origin only on cross-origin; no Referer on HTTPS-to-HTTP downgrade. Privacy-safe and breaks no analytics. The recommended explicit value.

### 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 (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 6 external resources have SRI*

- **[WARNING]** External script from pagead2.googlesyndication.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from www.googletagmanager.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from pagead2.googlesyndication.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from fundingchoicesmessages.google.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from fundingchoicesmessages.google.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from static.cloudflareinsights.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 (F — 0/100)

*no DMARC, no SPF*

- **[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]** No SPF record found — Without SPF (Sender Policy Framework), receivers can't tell which servers are authorized to send mail for your domain. Add a TXT record at the apex starting with v=spf1, ending in -all.
- **[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 (C — 60/100)

*Origin: **

- **[INFO]** Access-Control-Allow-Origin: * — unrestricted — Any website can read this resource's response. Appropriate for public APIs but not for user-specific content.
- **[INFO]** Origin reflection not testable with a single request — Some servers reflect the request Origin header. This requires manual testing with a crafted Origin header.

- **[PASS]** No images on this page

### JS Execution Cost (C — 60/100)

*1040ms total JS execution*

- **[WARNING]** https://pennycalc.com/: 256ms CPU time
- **[INFO]** https://www.googletagmanager.com/gtag/js?id=G-8DBK...: 214ms CPU time
- **[INFO]** https://fundingchoicesmessages.google.com/i/ca-pub...: 158ms CPU time
- **[INFO]** https://pagead2.googlesyndication.com/pagead/manag...: 138ms CPU time
- **[INFO]** Unattributable: 124ms CPU time
- **[WARNING]** Third-party scripts: 785ms (75% of total)

### Font Loading (A+ — 100/100)

*No web fonts (system fonts)*

- **[PASS]** No web fonts loaded — system fonts are fastest

### JS Bundles (C — 60/100)

*8 scripts, 278 KB unused*

- **[WARNING]** https://pagead2.googlesyndication.com/pagead/manag...: 148 KB unused (83%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://www.googletagmanager.com/gtag/js?id=G-8DBK...: 66 KB unused (42%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://fundingchoicesmessages.google.com/i/ca-pub...: 36 KB unused (53%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://pagead2.googlesyndication.com/pagead/js/ad...: 29 KB unused (53%) — Consider code splitting or tree shaking to reduce unused code.
- **[INFO]** Total unused JavaScript: 278 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) (A+ — 100/100)

*HTTP/3 advertised via Alt-Svc*

- **[PASS]** HTTP/3 (QUIC) is supported — First-load mobile users on cellular networks see meaningful latency improvements with HTTP/3. The QUIC transport collapses TLS + TCP handshakes into one and recovers faster from packet loss.

### 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 (A+ — 100/100)

*Main HTML max-age=0 (≤ 5min) is appropriate*

- **[PASS]** Main HTML max-age=0 (≤ 5min) is appropriate

### 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 (B — 80/100)

*20 resources · 530 KB · 278 KB savings available*

- **[PASS]** Within 1MB page-weight target
- **[INFO]** ~278 KB of savings available
- **[WARNING]** 15 third-party resources (93% 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]** 1 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 — 95/100)

*158 links checked, 157 healthy, 1 broken*

- **[WARNING]** 157 of 158 links are healthy
- **[WARNING]** Broken link: about:blank — Found in <iframe src>. Get "about:blank": unsupported protocol scheme "about"

### Mixed Content (A+ — 100/100)

*No mixed content detected — all resources use HTTPS.*

- **[PASS]** No mixed content detected — all resources use HTTPS

### Open Graph (A+ — 100/100)

*Open Graph tags are well configured for social sharing.*


### 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)

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

- **[INFO]** Missing recommended property "sameAs" for Organization — Adding "sameAs" can improve how search engines display your content.
- **[INFO]** Missing recommended property "potentialAction" for WebSite — Adding "potentialAction" can improve how search engines display your content.
- **[PASS]** 3 JSON-LD blocks found

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

*3 JSON-LD block(s) declaring 3 schema type(s)*

- **[PASS]** 3 rich-result schema type(s) declared — Inventory of structured-data types on the page (each may unlock a different SERP feature):

FAQPage, Organization, 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 (A+ — 100/100)

*No images to analyze*


### Autoplay Media (A+ — 100/100)

*No autoplay media on the page*

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

## Infrastructure

### DNS Records (A+ — 95/100)

*2 A records, 39 ms lookup*

- **[PASS]** Resolves to 2 IPv4 address(es)
- **[PASS]** Has 2 IPv6 (AAAA) record(s)
- **[PASS]** 2 nameserver(s) configured
- **[INFO]** No MX records — email not configured via DNS
- **[INFO]** No SPF record found in TXT records — SPF helps prevent email spoofing. Add a TXT record starting with 'v=spf1'.
- **[PASS]** DNS resolution time: 39 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 (C — 60/100)

*0/4 IPs match cert SAN*

- **[INFO]** PTR lookup failed for 172.67.159.243: lookup 172.67.159.243: 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.
- **[INFO]** PTR lookup failed for 104.21.41.43: lookup 104.21.41.43: 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.
- **[INFO]** PTR lookup failed for 2606:4700:3033::ac43:9ff3: lookup 2606:4700:3033::ac43:9ff3: 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.
- **[INFO]** PTR lookup failed for 2606:4700:3037::6815:292b: lookup 2606:4700:3037::6815:292b: 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+ — 100/100)

*Mean 39ms across 3 resolvers (spread 36ms)*

- **[PASS]** Cloudflare: 25ms
- **[PASS]** Google: 31ms
- **[PASS]** Quad9: 61ms

### Redirect Chain (A+ — 100/100)

*No redirects — direct access*

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

### IPv6 Readiness (A+ — 100/100)

*IPv6 reachable (17 ms)*

- **[PASS]** IPv6 is configured and reachable at 2606:4700:3033::ac43:9ff3, 2606:4700:3037::6815:292b

### Crawlability (A+ — 100/100)

*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
- **[PASS]** robots.txt references 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)

*Pennycalc.com — via Cloudflare, Inc., 2 months old*

- **[PASS]** Domain registered until Mar 8, 2027 (10 months remaining)
- **[INFO]** Domain is only 2 months old — Newly registered domains may face SEO trust challenges. Search engines generally give more authority to older domains. This is informational — not a problem to fix.
- **[INFO]** DNSSEC is not enabled — DNSSEC protects against DNS spoofing attacks. While not required, enabling DNSSEC adds an additional layer of security. Contact your DNS provider to enable it.
- **[PASS]** Registrar: Cloudflare, Inc.
- **[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.
