- **[PASS]** X-Content-Type-Options is properly configured
- **[PASS]** X-Frame-Options is properly configured

- **[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.

*4 of 10 CSP checks passed*

- **[INFO]** Raw CSP policy
- **[PASS]** default-src directive is set

- **[PASS]** No wildcard in script source
- **[PASS]** object-src falls back to default-src
