## Security

### Security Headers (F — 30/100)

*1 of 10 headers properly configured*

- **[WARNING]** HSTS is missing includeSubDomains — Without includeSubDomains, subdomains can still be accessed over HTTP.
- **[WARNING]** X-Content-Type-Options header is missing — This header prevents MIME-type sniffing, which can lead to XSS attacks. Set it to 'nosniff'.
- **[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.
- **[WARNING]** Referrer-Policy header is missing — Controls how much referrer information is sent with requests. Set to 'strict-origin-when-cross-origin' or stricter.
- **[WARNING]** Permissions-Policy header is missing — Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features.
- **[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.
- **[WARNING]** X-Powered-By header reveals technology stack — This header discloses server technology (e.g. Express, PHP), helping attackers target known vulnerabilities. Remove it.
- **[WARNING]** Server header reveals version information — The Server header discloses the software version, aiding attackers in targeting known vulnerabilities. Remove the version number.

### Content Security Policy (B — 70/100)

*2 of 10 CSP checks passed*

### Carbon Budget (F — 30/100)

*85th percentile*

- **[WARNING]** 1.85g CO2 — above the median website (0.60g) — Heavier than an estimated 15% of websites. Reducing page weight, optimizing images, and removing unused JavaScript would lower the carbon footprint. See the Performance tab.
- **[INFO]** Estimated 85th percentile — Compared to: top 10% = 0.20g, target = 0.50g, median = 0.60g per page view.
