## Security

### Security Headers (F — 5/100)

*1 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.
- **[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.
- **[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
- **[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 (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 1.2, 7 checks passed*

- **[PASS]** TLS 1.2 is used
- **[INFO]** TLS 1.3 is not negotiated — TLS 1.3 offers improved performance and security. Consider enabling it.
- **[PASS]** Strong cipher suite is used
- **[INFO]** HTTP/2 is not negotiated — HTTP/2 provides multiplexing and header compression for better performance.
- **[PASS]** Certificate is valid (expires in 322 days)
- **[PASS]** Certificate chain has 3 certificates
- **[PASS]** Certificate uses modern signature algorithm
- **[PASS]** Certificate covers 21 domain(s)
- **[PASS]** Certificate is issued by a trusted CA

### Cookie Security (A+ — 100/100)

*No cookies set — no cookie security risks*
