## Security

### Security Headers (B — 75/100)

*7 of 10 headers properly configured*

- **[PASS]** Strict-Transport-Security is properly configured (consider adding preload)
- **[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

### Content Security Policy (D — 50/100)

*5 of 10 CSP checks passed*

- **[INFO]** Raw CSP policy
- **[PASS]** default-src directive is set
- **[CRITICAL]** 'unsafe-inline' found in script source — 'unsafe-inline' allows inline <script> tags, defeating CSP against XSS. Remove it and use nonces or hashes instead.
- **[CRITICAL]** 'unsafe-eval' found in script source — 'unsafe-eval' allows eval() and similar functions, enabling code injection. Remove it.
- **[PASS]** No wildcard in script source
- **[WARNING]** object-src allows plugin content — Set object-src to 'none' to prevent Flash/Java plugin exploits.
- **[WARNING]** base-uri directive is missing — Without base-uri, attackers can inject a <base> tag to hijack relative URLs. Set it to 'self' or 'none'.
- **[PASS]** frame-ancestors directive is set
- **[PASS]** form-action directive is set
- **[PASS]** upgrade-insecure-requests is enabled

### 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.
- **[PASS]** Certificate is valid (expires in 135 days)
- **[PASS]** Certificate chain has 4 certificates
- **[PASS]** Certificate uses modern signature algorithm
- **[PASS]** Certificate covers 6 domain(s)
- **[PASS]** Certificate is issued by a trusted CA

### Cookie Security (A+ — 95/100)

*1 cookies analyzed, 2 checks passed*

- **[PASS]** Cookie 'device_env' has the Secure flag
- **[WARNING]** Cookie 'device_env' is missing the HttpOnly flag — Without HttpOnly, this cookie can be accessed by JavaScript, making it vulnerable to XSS-based theft.
- **[PASS]** Cookie 'device_env' has SameSite=None
